The production of KLOP fire dampers is carried out by different manufacturers... The most famous company that creates fire-prevention technical structures of the named brand is WINGS-M. The company, which was founded only in 2002, quickly gained the confidence of the market consumer and today is one of the leading manufacturers of fire protection valves for industrial and residential buildings.
The first fire dampers in Russia were created at the WINGS-M enterprise. They were presented by anti-smoke ventilation mechanisms KDM 1. Later, the company established beneficial cooperation with the Swiss company BELIMO. Components from Switzerland were used for the production of the first models of KLOP 2 valves with a belimo actuator, enclosed in an explosion-proof housing.
Now the company WINGS-M is engaged in the production of technical equipment different types... The products of the domestic manufacturer are in demand among buyers. Most of all, customers are interested in fireproof valves of the following models:
- Bug;
- Treasure;
These varieties technical equipment differ from each other functionality, and are widely applied in various. This article will consider a KLOP brand valve, its specifications and the nuances of work.
How does a fire retardant valve work?
The KLOP 1 fire damper blocks the spread of fire through the air ventilation shafts in the event of a fire. The manufacturer manufactures this device in 2 modifications:
- with a round section, nipple;
- duct, equipped with 2 flanges.
Fire protection devices also differ in the type of drive. On sale, buyers will be able to find a fire-retardant valve with an electric drive KLOP 1 in the following varieties:
- electromagnetic (some of its models are equipped with a thermal lock);
- electromechanical (supplemented with thermal closing equipment).
There are models equipped with a case that well protects the internal mechanism from explosions. Such products are allowed to be used in accordance with GOST.
Fire-fighting products of the KLOP brand contribute to the rapid localization of the fire source, protecting people and property from the effects of smoke. Some of the models are equipped with special triggering devices, thanks to which the spread of fire through the rooms is restrained for 2 hours. KLOP fire-retardant valves are divided into 2 categories:
- open, which do not allow the fire to spread through the ventilation systems;
- closed (they are also called smoke).
The level of fire resistance of products varies, and depends on the expected operating conditions. The fire resistance limit for KLOP brand structures corresponds to the following values:
- EI 60, E60;
- EI 90, E 90.
Valves with these characteristics can operate in open or closed mode.
Fire dampers are located in a special housing, on the door of which is displayed useful information for the owner. Thanks to her, you can find out:
- Is there a constant power supply and voltage (50Hz / 220V) in the network?
- Fire door position (OZK closed, OZK open).
- About the "fire" signal.
In fact, the control panel is essential element the entire fire protection system. Structural components Fire-retardant equipment Bug are:
- a body having a rectangular cross-section;
- seals (located between the flaps and the body part);
- protective flaps;
- drive (with its help the leaves are rotated).
The valve is completed with 1 or 2 flaps. They are made of heat-resistant material, which is clad on top with sheets of durable steel. Flaps are installed in the inner part of the body. Their movement in the event of a fire is provided by sleeve bearings. The device works thanks to a thermal lock or an electric drive. The latter is reliably protected from damage by a removable casing. When voltage is applied to the equipment through the drive, the doors automatically close. If the product has a thermal lock, then its shutter is carried out due to the release of energy accumulated in the spring. This happens when the exposure temperature reaches 72 ºC.
Advantages of the KLOP valve. Product advantages
Fire-retardant valve KLOP 2 with belimo actuator and other designs similar type have their own classification. Equipment open type when a fire occurs in the building, it immediately slams shut, preventing fire and smoke from spreading beyond the localization site. Closed-type products function according to reverse principle... Initially, they are closed, and in the event of a fire, they open. 
Fire-fighting mechanisms of the KLOP brand are installed near ventilation systems in order to prevent the rapid spread of fire and smoke through them in the event of a fire. An interesting design modification is the explosion-proof product. Such a valve is installed in buildings where there is a high risk of explosions. By equipping the refractory ducts with flanges, their connection to ventilation ducts is quick and easy.
In order for the KLOP fire damper to work correctly and without interruption, it must be checked regularly. Diagnostic data of a fire-retardant structure must be entered into a special act.
The functioning of technical fire-fighting equipment is carried out by means of an electromagnetic drive. The manufacturer equips KLOP valve models with both electromechanical and spring drives. Below are the most popular modifications of the series.
- KLOP-1. The device is powered by an electromechanical or electromagnetic Belimo drive. Management is optional. The product is distinguished by its affordable price for middle-class buyers.
- KLOP-2. Fire dampers of this modification have several differences from the 1st model. They are characterized by the best aerodynamic performance, convenience and ease of installation.
- KLOP-3. This type of equipment is widely used in conditions where air is consumed at a high speed. Most often they are mounted in air ducts with large size section.
All types of KLOP fire protection dampers are lightweight and compact. They react in a timely manner to a fire that has arisen.
What do consumers think of a fire protection device?
Air ducts and ventilation systems permeate the entire building. If a fire occurs in the room, combustion products quickly spread through the ventilation channels. Buyers with dignity and with positive side appreciated a special damper device that closes the passage to fire and smoke. Everyone who has already seen the KLOP brand valve in action says that thanks to this tool, the fire resistance of the entire building is increased. The device can be easily installed with your own hands, but it is inexpensive. In addition, in specialized stores, you can pick up fire retardant devices for air ducts with a cross section different shapes(round, square, rectangular). They can be installed on the supply or exhaust ventilation system... The use of such structures makes it possible to minimize the damage caused by fire and to localize the source of combustion.
Features of installation of a fire-fighting device
Installation of a fire damper has its own nuances. They depend on what type of device is used for protection. If it is an open fire retardant valve, then it is installed regardless of the spatial orientation. True, then it is necessary to check the correctness of the installation and draw up an appropriate act. This work is performed by a representative of the fire inspection.
Installation of open-type fire-prevention dampers does not depend on the direction of the air flow in the ventilation system. The place for their installation is determined in advance, taking into account general rules technicians fire safety... An act of conformity of the device to the selected attachment site must be drawn up.
If the valve has closed type, then when installing it, the direction in which the combustion products are removed in the event of a fire is taken into account.
How is the cost of KLOP brand fire protection products formed?
Fire dampers Klop have several modifications that differ from each other not only appearance, but also by its functionality. The cost of the product depends on the model. The following aspects influence price formation:
- type of working drive;
- device dimensions;
- fire resistance level.
For example small valves fire protection cost 6-11 thousand rubles, and the price of the largest devices reaches 55 thousand rubles.
Fire dampers Bug have high resistance to high temperatures. They prove their effectiveness by reliably protecting premises from the rapid spread of fire.
