Manufacturing fire dampers CLOP is carried out by different manufacturers. The most famous company that creates fire protection technical designs the named brand is WINGS-M. The company, which was founded only in 2002, quickly gained the trust of market consumers 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 VINGS-M enterprise. They were represented by anti-smoke ventilation mechanisms KDM 1. Later, the company established profitable cooperation with the Swiss company BELIMO. Components from Switzerland were used to manufacture the first models of KLOP 2 valves with a belimo drive, enclosed in an explosion-proof housing.

Now the WINGS-M company is engaged in the production of technical equipment different types. Products domestic manufacturer is in demand among buyers. Customers are most interested in fireproof valves of the following models:

Bug;
Treasure;

These varieties technical equipment different from each other functionality, and are widely used in various. In this article we will consider a valve of the KLOP brand, its technical specifications and nuances of work.

How does a fire arresting valve work?

Fire damper KLOP 1 blocks the spread of fire through air ventilation shafts during a fire. The manufacturer produces this device in 2 modifications:

with round section, nipple;
channel, equipped with 2 flanges.

Fire protection devices also differ in the type of drive. On sale, buyers will be able to find a fire-retarding 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 housing 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 source of fire, 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 protection valves are divided into 2 categories:

open, which do not allow fire to spread through ventilation systems;
closed (they are also called smoke).

The level of fire resistance of products varies and depends on the intended operating conditions. The fire resistance limit of 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 it you can find out:

Is there constant power and voltage in the network (50Hz/220V)?
Position of the fire-retarding door (OZK closed, OZK open).
About the fire signal.

Essentially, the control panel is the most important element all fire protection system. The structural components of the fire-retarding equipment Klop are:

a body having a rectangular cross-section;
seals (located between the doors and the body part);
protective flaps;
drive (with its help the shutters are rotated).

The valve is equipped with 1 or 2 valves. They are made of heat-resistant material, which is lined with sheets of durable steel on top. The doors are installed in the inner part of the body. Their movement in the event of a fire is ensured by plain bearings. The device operates thanks to a thermal lock or electric drive. The latter is reliably protected from damage by a removable casing. When voltage is supplied to the equipment through the drive, the shutters automatically close. If the product has a thermal lock, then its shutter is carried out by releasing the energy accumulated in the spring. This happens when the exposure temperature reaches 72 ºC.

Advantages of the KLOP valve. Product benefits

The KLOP 2 fire-retarding valve with a belimo drive and other structures of a similar type have their own classification. When a fire occurs in a building, open-type equipment immediately slams shut, preventing fire and smoke from spreading beyond the localization point. Closed type products operate according to the opposite principle. Initially they are closed, but 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 modification of the design is the product with explosion protection. Such a valve is installed in buildings where there is a high risk of explosions. By equipping fireproof air 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. The diagnostic data of the fire-retarding structure must be included in a special act.

The functioning of technical fire-fighting equipment is carried out due to an electromagnetic drive. The manufacturer equips the KLOP valve models with both electromechanical and spring actuators. Below are the most popular modifications of the series.

BUG-1. The device operates from an electromechanical or electromagnetic Belimo drive. Control is optional. The product is distinguished by an affordable price for middle-class buyers.
BUG-2. Fire dampers of this modification have several differences from the 1st model. They are characterized by better aerodynamic performance, convenience and ease of installation.
BUG-3. Equipment of this type is widely used in conditions where air is consumed at high speeds. Most often they are installed in air ducts with a large cross-sectional area.

All types of fire protection valves KLOP are lightweight and compact in size. They respond promptly to a fire.

What do consumers think about the 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 ducts. Buyers with dignity and positive side evaluated a special damper device that blocks the passage of fire and smoke. Everyone who has already seen a KLOP brand valve in action says that thanks to this product the fire resistance of the entire building increases. You can install the device yourself without any problems, and it is inexpensive. In addition, in specialized stores you can select fire protection devices for air ducts with a cross-section different shapes(round, square, rectangular). They can be installed on supply or exhaust ventilation system. The use of such structures makes it possible to minimize the damage caused by fire and localize the source of combustion.

Features of installation of fire protection devices

Installation of a fire damper has its own nuances. They depend on what type of device is used for protection. If it's open fireproof valve, then its installation is carried out regardless of spatial orientation. True, then it is necessary to check the correctness of installation and draw up a corresponding report. This work is performed by a representative of the fire inspectorate.

The installation of open fire dampers does not depend on the direction of the air flow in the ventilation system. The location for their installation is determined in advance, taking into account general rules fire safety equipment. A certificate of compliance of the device with the selected mounting area must be drawn up.

If the valve has closed type, then when installing it, take into account the direction in which combustion products are removed in the event of a fire.

How is the cost of fire protection products of the KLOP brand determined?

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.
