Fire bug valve 1. Fire bug valve: advantages, disadvantages, product control features. Valves for maritime and wet areas
Fire damper KLOP-1 in the market of domestic fire dampers is perhaps one of the most famous and eminent.
Its certification and development of mass production was carried out in 1999, and the KLOP-1 valve became the first domestic certified fire damper, and the name KLOP-1 became a registered trademark. For some time, the Klop-1 valve was the only fire damper domestic production. Well-organized manufacturer marketing and work with design organizations made the KLP valve popular, often found in project documentation. Probably, this contributed to the fact that the name KLP-1 has become a household name, you may encounter such situations when the customer, when applying for valves, says: "I need to buy KLP-1", although the specific name of the valve is not indicated in his documentation and the valve KLP-1 can be replaced by other fire dampers with similar parameters.
The fire damper KLOP-1 is installed in the channels of general ventilation and air conditioning with mechanical draft induction. Fire-retarding (normally open valves) prevent the spread of fire through these channels, and smoke (normally closed valves) prevent the spread or removal of smoke.
The fire damper KLOP-1 is produced in the form of two modifications:
Klop-1(60);
Klop-1(90);
The difference between them lies in the limits of fire resistance.
Klop-1 (60) has a fire resistance limit of 60 minutes (1 hour).
Klop-1 (90) has a fire resistance limit of 90 minutes (1.5 hours).
The KLOP-1 damper can perform the functions of both a fire damper (damper in the "normally open" position) and a smoke exhaust valve - (damper in the "normally closed" position).
The valve body can be made both round and rectangular (square) section.
Klop-1 is intended for installation only in the channel. The drive that transfers the damper flap from the initial state to the working state is located outside the damper. To control the position of the damper, a special inspection hatch is provided on the valve. It is used when an air duct is connected to the valve on both sides and it is not possible to look inside the already installed valve through the flow area.
The body of the KLOP-1 valve is made of carbon (black) steel, subsequently painted. This KLOP-1 differs from the valve KLOP-2, the body of which is made of galvanized steel.
The damper of rectangular (square) section is equipped on both sides with flanges through which it is attached to the ventilation duct.
The round section damper can be made both on flanges and for nipple mounting in the ventilation duct.
Fire damper KLOP-1 is completed the following types actuators for damper flap control:
Electromechanical actuator BELIMO type BF(24), BF(220) or BLF(24), BLF(220) with a return spring with a supply voltage of 24V or 220V;
Electromagnetic EM (220), EM (24) or EM (12) - electromagnetic drive with a supply voltage of 12V, 24V or 220V;
ТЗ - spring drive with thermal lock;
ТЗ(М) - spring drive with thermal lock and microswitches;
When choosing an actuator for fire dampers, consider that:
Part 2 Art. 138 federal law No. 123-FZ prohibits the use of TZ and TZ(M) type actuators on NO fire dampers in Russian Federation.
The use of MV type actuators for NC and smoke dampers in the Russian Federation is contrary to clause 7.18 of SP 7.13130.2009.
The price of fire dampers KLOP-1, KLOP-2, KLOP-3, KOM-1, KDM-2 and KLAD-2 are given below.
The price of a fire damper with dimensions other than those indicated in the table is determined by the larger side. For example, the price of a KLOP-1 valve with dimensions of 400x200 is determined as the price of a 400x400 valve. The price of a KLOP-2 valve with dimensions of 600x350 is determined as the price of a valve with dimensions of 600x600, etc.

Valve options KLP 1
All KLOP-1 valves have channel type development. They are equipped with two flanges and external actuators. different types. > KLOP-1 valves with a round section can have nipple joints. Such valves are called nipple.
Normally open (NO) valves KLOP-1 are presented in several types of modifications. They can be equipped with an electromagnetic drive with a thermal lock capable of withstanding temperatures up to 72 ° C, or an electromagnetic drive without a thermal lock. Also, KLP valves can be equipped with BELIMO electromechanical actuators with thermal locking devices designed for temperatures up to 72 °C, or electromechanical actuators without such devices, and spring actuators with thermal locks that can withstand temperatures either up to 72 °С or up to 141 °С . In addition, KLOP-1 valves can be equipped with microswitches.
Normally closed (NC) and smoke dampers KLOP-1(90) and KLOP-1(60) are not equipped with thermal locks. Valves of this type, having small and medium dimensions, are equipped with an electromagnetic actuator. Large dampers KLOP-1(90) and KLOP-1(60) have BELIMO reversing actuators of the BLE or BE type or BELIMO electromechanical actuators equipped with BF or BLF return springs without TRU.
Installation of valves KLP 1
KLOP-1 valves retain their full performance when installed in any position. The design and further installation of such valves are made in accordance with calculations based on the availability of the valve for operation and accessibility to all devices that are located inside it.
KLP dampers are designed for installation indoors, where the air temperature ranges from -30 °C to +40 °C. They are installed in such a way that direct contact with natural precipitation or the formation of condensate on the valve flaps are completely excluded. If the environment surrounding the KLP valves contains aggressive vapors or gases, their concentration should not be too high. Otherwise, the aggressive environment will have a destructive effect on the metal from which the KLOP valves are made, and on the electrical insulation.
KLOP-3 dampers are designed mainly for air ducts of large cross section.
