How is the door closer adjusted? Adjustment of the "finishing" of the door leaf. Ways to install a door closer

Adjusting the door closer is a fairly simple procedure.

It is necessary when you are not satisfied with the pace of closing the doors - too fast or too slow.

Every person capable of performing at home minor repairs, will surely do the job.

All that is needed for this the first time is an instruction manual and a screwdriver. Fans of visual materials will surely find a lot on the Internet. detailed videos on this topic.

Basic information about door closers

Entrance door closer English language called door closer, literally - a door closer. With this mechanical device, you only need to open the doors - the door closer will close them itself.

The device not only makes it easier to close the doors, the main purpose of the mechanism is to reduce the load on the hinges and fittings, which wear out much less.

In addition, if in public places the doors do not always close tightly without it, which causes drafts and heat loss, then a simple mechanism successfully solves this problem.

Closers provide access control to the room, so their presence is mandatory on fire doors and emergency exits.

Today, these mechanisms are used not only at the entrance, but also on the internal passages in public spaces and even in private housing.

They close the door quietly, smoothly and tightly. You can adjust the force required to open the door.

The device can be located above the doorway, below in the door frame or in the door itself.

Closers mounted at the top are mechanisms open type, all others are hidden from view.

The choice of a particular model depends on two main parameters - the weight and width of the door. The higher these values, the more powerful the door closer mechanism should be.

Each manufacturer develops strict recommendations for installing devices, and if these instructions are not followed exactly, then the mechanism may soon need to be repaired.

Besides, various models designed for various conditions operation, such as temperature range.

Even if you have a thermostable model, by adjusting the closing speed according to the season, you can extend the life of the mechanism.

Often people, entering the room in the cold, unconsciously try to quickly close the door behind them if the closer is too slow. This damages the seals and the mechanism may soon need to be repaired.

There are special thermal dampers for closers. When the temperature environment rises, the oil becomes thinner and flows faster inside the device.

To avoid this, the thermal damper expands to compensate for the lack of oil thickness. When the outside temperature drops, the thermal damper will act in reverse.

When choosing a specific model, pay attention to compliance with international standards.

The requirements of the EN 1154 standard adopted in Europe exceed the rather lenient GOST of the Russian Federation, so many closers that meet the requirements of GOST do not comply with EN 1154.

Additional functions

Many models of closers perform various functions and, accordingly, they have elements of their adjustment. Below is information about some of them.

The wind brake or opening damper allows you to set the maximum door opening speed.

This feature is useful for room transitions to avoid damage to walls and doors if they are thrown open too quickly.

Adjustment schemes:

For entrance doors, this function is simply necessary, because it does not allow drafts and gusts of wind to control the opening process.

The hold-open closing stop function must not be used on fire exits where electromagnetic or electromechanical impulse actuated latches are used.

For fire and smoke barriers, the function of coordinating the closing of the leaves is necessary, it is also installed on double-leaf doors.

This is a lever design that is installed on the door frame in addition to the door closer.

The delayed closing is necessary to make it easier for people with disabilities to enter the premises. handicapped, with baby carriages so that several people can pass at a time.

Typically, the delay is set to about 30 seconds. The delayed closing function should not be used in places where there is a large flow of people - this can lead to injury and breakage of the closing mechanism.

Another useful feature is the throttle adjustment. With its help, you can speed up the closing of the doors at the last stage.

When the sash is in the range of 0 - 15 ° until it is completely closed, the person has already managed to move away from the entrance, the closing process can be accelerated. The function makes it easier to click the lock and, again, avoids heat loss.

Closer adjustment process

Do-it-yourself door closer adjustment is a fairly simple process even for people who do not have special engineering abilities, which cannot be said about repairing the mechanism, which is not always possible.

On this topic, you can watch the video in the article, use the manufacturer's instructions or recommendations from this article, but you should not adjust the mechanism intuitively.

If, as a result of your manipulations, oil begins to drip from the door closer, then its repair is no longer possible - the device will have to be replaced.

So, how to adjust the door closer? Remove the cover from the mechanism and look for the control valve. To do this, check the diagram in the instructions.

By turning the control valve counterclockwise, you can slow down the closing, in order to speed up the process, you need to turn it clockwise. More expensive models closers have two or even three such valves.

They divide the closing process into two or three stages, and in each range the speed can be adjusted separately.

Important point! Do not turn the control valve more than two turns from the zero position.

The opening forces can be set by adjusting the door closer.

Turning the adjusting nut counterclockwise makes the process easier, while turning it clockwise will require more force to enter.

Adjustment of the closer must be used for routine inspection of the mechanism - whether oil is leaking somewhere.

Leaks occur more often in winter due to damage to the hull, which led to its depressurization.

Such a breakdown turns the closer into an ordinary spring - it ceases to perform its functions and only slams the doors loudly.

If damage is detected on the body in time, then repairs can be made and sealed to prolong the life of the door closer.

But if the moment is lost and the hole is too big, then there are no other options but to buy a new device.

When adjusting the door closer, you can set both the closing delay function and the full stop function. The delay is provided by tight tightening of the latch designed for this.

You need to tighten it by opening the door by 90 - 100 degrees - the position in which the closing delay will be performed.

As a rule, if one person passes, then he does not need to open the doors so wide, and the function will not work unnecessarily.

The hold-open function keeps the door open until you make a closing motion that releases the lock.

In the same way as with the opening delay, the function will not work if the door is not opened wide enough.

If the adjustment is performed twice a year (at the entrance from the street four times), then this will extend the life of the mechanism.

Is it possible to manage Everyday life without door closers?

Of course you can. It's not hard at all to open and close behind you.

True, if the hands are busy, then it already delivers some inconvenience. And if there is a spring, then it’s quite a disaster.

Sometimes, a passing push in the back is comparable to the acceleration of free fall.

Therefore, setting up a door closer, even a spring one, is a rather relevant thing.

Of course, setting up this very closer will not be difficult.

The task of these devices is to close behind incoming and outgoing people.

Moreover, to do this according to a certain algorithm:

Do not interfere with easy and free opening
Do not close, at a certain opening angle
Close at an adjusted, comfortable speed
At the end of your movement - slowly, without knocking, clap, with a certain effort

A similar algorithm should be performed for doors of any design and purpose. There are a lot of designs and operating conditions of doors:

outdoor
Internal
Interroom
Swing
metal
Rights
Left

Each door has its own weight

When choosing a specific model of the closing mechanism, all of the above options must be considered. This is especially true for weight. door leaf and temperature conditions.

In addition, the closers themselves are available in several modifications:

With slide cam type mechanism.
It has a smooth glide, but is used only for light canvases.
With gear-lever mechanism. In this case, the movement of the door leaf is transmitted by a system of levers and a rack and pinion mechanism. The gear rack, performing reciprocating movements, plays the role of a rod distilling oil through adjustable jets.
Outdoor execution. A similar mechanism is built into the floor when it is laid. Not widely used.
Concealed installation. The working mechanism is built into the body of the door leaf.
Overhead type. The most widely used type of door closer. It is used for canvases of various weights. When temperature conditions change, it needs to be adjusted.

When choosing a door closer for a particular door, it is necessary to strictly compare its weight and performance with the technical capabilities of the device.

Why is adjustment needed?

It is easy to imagine the work of a poorly adjusted closing mechanism.

If we take 2 extreme cases of poor adjustment, we get the following.

In the first of them, the closer will work like a strongly tightened spring.

People will have a hard time getting past it.

To top it off, the door leaf will knock with force on its box.

In order to correct the situation without adjusting the device, it will be necessary to hold it.

In the second case, it simply will not close or close only partially.

This is how the Diplomat door closer is configured. Its adjusting screws are located on the end surface of the device. Adjusting this screw changes the speed of the web in the range of 15 0 - 180 0 .

Such adjustments must be made with extreme caution. A fully turned out adjusting screw will inevitably cause system depressurization and oil leakage. The closer will be completely disabled.

Dohlop installation

Adjusting the door closing speed must be carried out regularly - at least 2 times a year. This is also necessary for purely preventive purposes, as well as in connection with a possible change in the physico-chemical oils.

At low temperatures it becomes sticky. At high values- becomes too liquid. In the first case, the door does not close well. The second is too fast.

The same arguments are relevant for such a function of closers as a close. This is especially important for doors with soft seals, magnetic or combination locks.

For such doors, the last moment of closing is very important. This range is in the range from 0 0 to 15 0 . In this range, the leaf must close slowly and securely.

Situations with increased dynamics or incomplete closure are unacceptable.

To adjust the door closer "Bulat" or close to it in design - "Diplomat", for these purposes a screw for adjusting the catch is provided.

Due to its rotation, the characteristics of movement will change in the range from 15 0 .

The screws for adjusting the speed and rebound are located side by side on the end panel of the device.

This butt is directed towards the door hinges.

As in the case of the speed adjustment screw, the rebound screw requires the same care when manipulating it.

Adjustment of the catch-up should be carried out only after the debugging of the speed characteristics is completed. Turning the adjusting screw clockwise decreases the speed.

Turning against it - makes the speed more. To avoid technical problems, do not make more than 2 turns in this direction.

Operating rules

These rules are simple and very clear. Devices designed to close doors are of low cost and are not equipped with various anti-vandal devices.

In this regard, they must be handled with care and rather delicately. Having chosen a closer, you need to make sure that its characteristics correspond to the conditions where they want to put it:

Since closers are divided into classes from small - EN1 to large - EN7, then it is worth choosing them in accordance with them. It should be noted that these classes are associated not simply with mass, but with inertial mass. In other words, not only weight matters, but also the dimensions (shoulder) of the canvas. An appliance rated at 40 kg (EN1) cannot close a metal door weighing 120 kg (EN7).
Don't help him with his work.
It is not necessary to keep the sash open if the mechanism does not have such a function.
There is no need to thoughtlessly turn the valve adjusting screws.
Coordinate with the seller of the equipment the issue of setting it up with the left or right opening.

A beautiful door, a functional door closer, a bit of luck in adjusting it, and a bit of luck in life. Here is the working formula happy person. This article is one of the components of this formula. And luck is always there.

The video shows the installation of a door closer:

Today's technologies make life much easier. For example, a device such as a door closer eliminates the need to constantly check whether the front door of the entrance is closed. Today, manufacturers produce several types of such a device, which are installed on entrance doors or interior doors. Pretty handy, easy to set up and adjust.

In order to choose the necessary model of auto-closers for yourself, it is worth considering what types there are, and for which doors they are intended. The closer model should be selected taking into account the parameters of the door, namely the width and weight of the door leaf. You should also consider the temperature range at which the door closer will have to work.

The main types of automatic closer mechanisms:

Top overhead closers are mounted on the wall and firmly held on top. They provide smooth closing of the door. Mechanisms with a gear drive or a sliding rod are produced. The cost of such a mechanism is relatively low. Such closers are very easy to install.
Floor closers are much more expensive than the first type and require special installation conditions. Most often, they are used for a door that opens in both directions. Also, such a mechanism is very convenient to install on glass and intercom doors.
Hidden closers are designed for installation directly into the door leaf and frame. To install this type of closer, you will need a door with a thickness of at least 40 mm. They are almost invisible. Installation of this type of door closer is quite complicated and requires special knowledge and skills.

The street closer is equipped with a mechanism that is lubricated with a special liquid to increase the resistance to high temperatures. In other words, if you install a closure designed for use during indoor areas on the access door, its performance will deteriorate significantly, and the service life will be greatly reduced.

What is a door closer and how does it work?

In its work, the door closer is similar to the spring mechanism, which was previously installed on doors and gates. But the disadvantage of such a device was that the door slammed very loudly and closed abruptly. With the advent of modern devices for automatically closing the door, the problem with the formation of noise has gone into oblivion.

The principle of operation of a door closer is very simple.

The main working part of this device is a spring and an oil shock absorber, which is responsible for the smooth closing of the door. Through a special valve system, the oily liquid, depending on the direction, flows from one chamber to another during operation.

Peculiarities:

The movement of oil is hydraulic system regulated channels.
The oil in the mechanism has a rather viscous consistency, due to which the opening and closing process runs smoothly and silently.
The force and speed with which the mechanism works depends on the type of device.

Parameters are easily adjusted using special adjusting screws. The tighter the screws are clamped, the slower the fluid flows through the channels. You can remove and adjust the door closer with your own hands, having carefully studied the principle of operation of the mechanism.

Installation and adjustment of the door closer

Basically, door closers are designed for installation on front doors. During installation, the body of the closer is positioned so that it is in the room, it is impossible to remove it from the outside. This arrangement of the case provides additional protection of the mechanism from moisture, dust and dirt.

To install a door closer, you will need:

Drill;
Ruler;
Simple soft pencil;
Screwdriver.

Mounting materials are included with the mechanism. For ease of installation, most manufacturers complete the device with installation templates that show all parts of the closer in life size. Also on these templates you can see the places where it is necessary to make holes for fasteners. Using a template, holes are made in the intended mounting location of the closer. Then proceed to the installation of the device itself. The body is attached first, which subsequently must be connected to the thrust lever. If you follow the instructions, the installation of the door closer will not take much time.

As a rule, closers have different design and the location of the adjustment screws. Adjustment of the closer is carried out according to the same scheme, regardless of the design of the device - by turning the screws clockwise, the speed and strength of the closer increases, or by turning the screw counterclockwise, it means slow closing of the door.

Most often, to tighten the screw, it is enough to make a quarter turn. If you upset the balance and strongly tighten or unscrew the screw, you can completely upset the operation of the mechanism, which is then difficult to restore. Incorrect adjustment may damage the device.

Instructions: how to adjust the door closer after installation

After installing the door closer, its adjustment is necessary for the optimal rate of closing the front or street door. It is necessary to adjust the door opening speed with the help of screws, which are located on the front side of the case under a special protective cover.

This function is especially useful when installing the door closer on interior door.

Slow closing will avoid damage to the walls. There are several additional functions that help to set the optimal closing and opening of the door.

Locks with electromagnetic or electromechanical action:

Are established on entrance doors;
Where is the intercom located?
On the door, which restricts the access of strangers to the entrance.

Such a mechanism closes the door to the end and opens only with a special key. Closers with a delay function are needed in public places to facilitate access to the premises for people with disabilities. Most often, the delay is set to 30-40 seconds. Adjustment of the argument is applied when closing the door at the last stage. This function makes it easier to click the lock and helps to avoid the rapid escape of heat from the room.

Adjustment of the door closer during operation

If it becomes necessary to personally adjust the pace of closing and opening the door, you need to pay attention to the basic rules and nuances of the process. Each device comes with detailed instructions which will help to carry out this process correctly.

Basic adjustment steps:

The first screw must be turned half a turn counterclockwise to adjust the reach;
The second quarter-turn screw clockwise speeds up the opening;
The third screw, which is located on the side of the case, regulates the force of movement.

It is very important to remember that in order to weaken or increase the pace, the screws must not be unscrewed more than 2 turns. This action will cause oil to leak out. It is impossible to repair the door closer at home. For this reason, adjustments must be made carefully, following all directions in the manufacturer's instructions.

Quite often, the closer needs additional adjustment. If the closer works hard, and when you open the door, you need to make an effort - then you need to loosen the screws, and the door will work softly. Sometimes it becomes necessary for the door to be constantly open, loosening the screw completely will help with this.

The screw keeps the door open for as long as necessary.

The screws can be located on the side or on the front side, it all depends on the mechanism. You can find out the location of the screws by looking at the instructions, where the manufacturer indicates the location of all parts and parts of the closer. To date, several models of closers are in great demand, which are easy to operate, install and adjust.

Experts have created a list of the most popular models:

Dorma– closers are suitable for installation on metal doors outdoor and indoor use.
Bulat frost-resistant, made of durable metal alloy.
Diplomat It is made of high-strength steel, which allows it to withstand sudden temperature changes.
Apecs have an additional function of permanent fixation.

All of these models have a lot of advantages, thanks to which they are becoming more and more popular every day. Most manufacturers, in the manufacture of closers, use only high-quality materials that increase the life of the product even under the heaviest loads.

Do-it-yourself door closer adjustment (video)

Summing up, we can safely say that closers are useful and convenient fixture. They are easy to install and operate. All models are equipped with special bolts, which regulate the speed and force of retraction or closing of the door. Additional functions of the door closer allow you to keep the doors in the open or closed position. It is necessary to purchase closers from official representatives who can sell according to OKVED.

The closer is a device for returning the door to its original position in the automatic operation mode. This device silently and softly covers the opened sash. If necessary, it holds the door leaf open. Many doors are equipped with a modern practical device. However, like any technique, the door closer needs maintenance, adjustment and troubleshooting.

Types of mechanisms and their device

To better understand the principle of the functioning of the mechanism, you need to analyze its basic varieties, so it will be easier to figure out how to correctly debug the door closer.

For the most part, these two types of this device are practiced:

cam slide - performs soft sliding, practiced for canvases with low weight;

gear lever - the most common type of mechanism, the movement of the spring is realized through gears, it can be used even for massive door panels.

According to the method of mounting, fixtures can be divided into three main types:

Overhead structures (overhead)- these are the most uncomplicated devices to use, their functions can be adjusted using a few screws or valves located on the case panel. They are mounted at the top of the sash, which is extremely convenient for installation. For entrance street doors, specialized oil-filled devices are manufactured, adapted for operation in hot or cold climates.

Floor. Floor-mounted systems are also relatively easy to set up. They have shown themselves excellently in banking institutions, offices, shopping and entertainment complexes and where to appearance door high requests. These devices are integrated into the floor and are almost invisible to visitors. Sliding type regulator mechanisms are used, designed for doors weighing no more than 100 kilograms.

Devices hidden type it is quite problematic to adjust it yourself, since they are removed inside the door leaf or on the floor, which complicates access to them. Devices are in demand where a thorough cosmetic finish and an ideal main facade are needed.

According to the principle of operation of the device are as follows:

hydraulic;
pneumatic;
electrical.

fixture structure

In the structure of this device the following parts and mechanisms are included:

die-cast aluminum body;
spring;
piston;
adjusting screws (valve);

gears;
needle bearing;
rubber seals;
fixture.

The principle of operation of the closer

The basic component of the design is a spring system, which, when the door is opened, is compressed and accumulates the energy required to close the door. The compression process is carried out by transferring the force of the traction device to the spring. Toothed gears and racks move the piston, while the oil internal channels flows into the free part of the body. During the reverse stroke of the door, the spring straightens and provides a soft closing.

In what cases is the procedure necessary?

Correcting the operation of a door closer is a fairly simple matter. Setup can be done without problems with my own hands. It is worth understanding in what situations it may be necessary to adjust the parameters of this mechanism. The first thing to remember is that the duration of the uninterrupted functioning of any mechanism is directly based on the quality of its maintenance throughout the entire period of operation. As a result, 1-2 times a year, it is required to inspect the door closer and eliminate minor malfunctions. This is especially important during the transitional change of seasons.

In summer and winter, the climate conditions are enormously different. Most of the closers are filled with oil, and as you know, any liquid changes its state when the ambient temperature changes. In particular, in winter, the oil becomes thicker and the door leaf moves more slowly. In summer, everything turns out the opposite, so you need to prepare the door closer to the required level. Adjustment of the device is also needed if you notice any malfunctions or you simply do not like the settings you have set. If the device starts to slow down or the closing of the door leaf is too hard and fast, in jumps, long time is not attracted, all this can be tried to correct. Things get a little more complicated when the device is out of order, since a simple setup will no longer be effective and repair work will need to be done.

Instructions for setting up a door closer with your own hands

To adjust the device, it is not necessary to invite the master. It is enough to have a minimum set of tools and certain skills. The whole procedure will take a minimum amount of time and will make it possible to achieve the desired result by adhering to the steps listed below.

Before proceeding with the procedure itself, remember that the main thing is not to overdo it with the control valves (screws). It is acceptable to make only 2 turns, then difficulties may arise. The oil in the pressurized reservoir may spill out and the hydraulic system of the closer will eventually lose its functionality.
To adjust the closing speed of the door leaf, it is necessary to learn only one trend - by turning the valve clockwise, it will gradually decrease. If the action is performed in the opposite direction, the closing speed will increase.

There is a solution to the problem of only one person being able to get through. Since there is a third valve, the adjustment of which can keep the door in a fixed position for a certain time. Therefore, even a group of people will be able to freely enter the room.
Such a problem as a lack of effort to completely close the door leaf is eliminated by adjusting the valves responsible for closing speed.

Finding the perfect solution can be a key problem when adjusting a door closer. The main task is to close the door to the end so that there are no gaps. It is necessary to choose the right perfect time, which the door leaf can be in the open state. It is also required to make silent closing possible, hard impacts on door frame. This can cause damage to the canvas. BUT the worst option there may be a loss of efficiency of the mechanisms responsible for proper operation.

How to adjust the closing force so that the door does not slam?

For self-tuning, you will need a flat-end screwdriver or an Allen wrench. The door opens to the end, special valves are fixed, located at the end of the device. Full fixation is carried out with the door leaf closed. By changing the degree of tightening of the valves, you can adjust the door to an extremely comfortable closing. Valve number 1 is responsible for the closing force of the door.

If the fully open door closes too quickly at the beginning, the valve must be tightened, and if it is slow and it is necessary to increase the speed, on the contrary, unscrew it. Valve number 2 is responsible for the speed of complete closing of the door leaf (slam). Separate modifications have a third valve that adjusts all the efforts of the door closer. With proper adjustment, the door leaf moves smoothly, without jerking. result correct installation and a competent attitude of the door closer will become a long service life.

Important! You can not turn the control valves completely. Otherwise, they will stop exercising their functional purpose even after returning them to their place.

How to weaken the opening?

Quite often, the closer requires additional configuration. If the mechanism works hard, and in the process of opening the door it is necessary to make efforts - it is necessary to release the valves, the door will begin to function smoothly. Valves can be placed at the end or on the front side, it all depends on the modification of the device. You can find out the location of the valves by looking in the manual, where the manufacturer indicates the location of all the components and elements of the door closing mechanism.

Position open

At times there is a need for open door over a relatively long period of time. It is worth figuring out how to adjust the device so that the doors do not close, but stay open. In many modifications of door closers, there is an auxiliary hold open option for this. To set it up for this mode, you need to open the door approximately 90 degrees, and then tighten the specialized lock. After such simple actions, it will be possible to leave the door leaf open when opening it to the configured degree. A special latch will be activated in the device and will hold the door in this position for as long as necessary. If you need to close the door, you just need to pull it towards you, and it will be removed from the latch. If the door is not opened to the limit, it will move in the same way as always, without stopping.

significant violations of the speed of the door leaf, avoiding normal parameters eliminated by turning one of the adjustable screws in the required direction, which will vary from the speed of opening (closing) the door;
it is possible to increase (decrease) the speed of closing by turning the second valve clockwise or against it;
if you turn the adjustment nut in the required direction, you can make corrections to the force of the spring tension;
turning the adjustable nut will correct the valve responsible for the opening angle of the door, as a result of which it will open smoothly, it will be easier to swing open.

We can safely say that closers are practical and convenient devices. They are easy to install and operate. All modifications are equipped with specialized valves, through which you can adjust the force and speed of opening or closing the door leaf. Closer options make it possible to keep the doors open or closed. But remember - you need to buy these devices from distributors who have the right to sell in accordance with the all-Russian classifier of types of economic activity.

How to adjust the door closer with your own hands, see the following video.

With the development of technology, human life has become much easier. With such a simple device as a door closer, you will forget about the need to double-check if the doors are closed. Today, devices are available in several types and are represented by goods different manufacturers, differ in belonging to different price categories. We will figure out how to mount the door closer and adjust the door closer, how long this process will take and how difficult it is.

The main types of mechanisms and their internal structure

To choose a closer option for a door, you first need to understand the types of mechanisms and their intended purpose. The choice should be based on the parameters of the door, namely? width and weight of the structure. In addition, please note temperature regime the premises where the installation and operation of the element is planned.

The main options for auto-closers include:

Top overhead, which are mounted on the wall and firmly fixed on top of the door. The mechanism ensures smooth closing and a snug fit of the door. They produce two types of product models: with a gear drive or a sliding rod. The mechanisms of this category are distinguished by their low cost and belong to the category of affordable goods. In addition, they are easy and quick to install.
Floor closers. These products, in comparison with the previous considered option, are distinguished by a high cost. In addition, they require special installation conditions. Most often, such mechanisms are used for doors that open in both directions. It is convenient to install such a closer option for an intercom door or a glass structure.
Hidden closers. The products are intended for installation directly into the door leaf or frame. They are installed on doors with a thickness of at least 40 mm, becoming almost invisible. Installation is complex, requires special knowledge and skills.

Peculiarity street closer for the door - equipping with a special mechanism lubricated with a liquid that increases resistance to high temperatures. That is, if you install such a closer designed for interior doors or used in installation on entrance doors with inside, outside, then its performance will deteriorate significantly, and the service life will decrease.

The principle of operation of the door closer

This device is similar in its work to the spring mechanism, which was previously installed on gates and doors. The disadvantage of such a device was far from smooth closing, and sometimes pops of the closing structure. As soon as modern automated systems, providing a smooth door movement, the problem with the formation of noise was solved by itself.

The main working part of the closer is a spring and an oil shock absorber, which is responsible for a smooth ride. The oily liquid circulating inside special valves flows from one chamber to another.

Features of mechanisms

To the number distinctive characteristics closers include:

Oil circulation occurs through a hydraulic system, adjustable valves.
Smoothness and noiselessness at opening/closing of a door is provided thanks to a viscous consistence of oil.
Depending on the type of device, the strength and speed of the mechanism may vary.

It is easy to adjust the parameters of the closer with the help of special adjusting screws. The tighter they are clamped, the slower the fluid flows inside the cylinder. Having carefully read the principle of operation of the mechanism, it becomes clear that it is not so difficult to remove and adjust the door closer.

How to mount and configure the door closer yourself

The main purpose of closers is smooth closing front door. When installing, make sure that the body of the product is on the inside of the room, which makes it impossible to dismantle the product from the outside. It contributes additional protection mechanism from the penetration of moisture, dust, dirt.

Mounting tools

During the installation you will need:

Drill.
Ruler.
A simple pencil with a soft lead.
Screwdriver.

There is no need to buy fasteners separately, they are included in the delivery of the door closer.

What does the installation process look like?

Some of the manufacturers add installation templates to the product kit with life-size images of all parts of the mechanism and the intended locations of holes and fasteners.

Having studied the template and the details of the installation of the mechanism, they proceed directly to the process of installing the device. First, the body is fixed, which, at the second stage, is connected to the traction lever of the structure. Following the instructions, you will see that the installation technology is not difficult and takes very little time.

Please note that the closers are structurally different, the location of the adjusting screws also varies.

Features of adjusting the door closer

The adjustment is carried out according to the same scheme, regardless of the design of the closer. By turning the screws clockwise, the speed of the mechanism and its strength is increased or, by rotating the screw in reverse side, means slower closing of the door.

When working with this design, try to turn the screws slowly and carefully - this is one of the recommendations of experts.

To tighten the screw, it is enough to make a quarter turn. By knocking off the balance and strongly tightening or unscrewing the screw, you run the risk of completely upsetting the operation of the mechanism, which as a result will be problematic to restore.

Incorrect adjustment of the door closer leads to its breakdown. This is worth paying attention to.

How to properly adjust the door closer after installation

This procedure is carried out in order to obtain the optimal rate of closing the front or street door. Adjusting the opening speed, as mentioned above, is carried out using screws located on the front side of the case and hidden under a special protective cover, which is especially good when installing the mechanism on an interior door. So the design looks more aesthetically pleasing.
