What kind of environment is the fire damper normally used?

What kind of environment is the fire damper normally used?

Air supply, including ventilation, such as fresh air and exhaust, is a very wide range of custom tailored multi leaf regulating valves, such as factory floor and production site air. Due to harmful gas generation, it is necessary to discharge outdoor air and to transport outdoor air into the room. At this time, we need to use large and low pressure air conveying pipes. The spiral fire damper is very suitable. In general, galvanized iron pipes are used, corrosive stainless steel pipes are used in special damp places.

Send a cold wind. The most common is the central air conditioning pipeline, this piping needs to add the heat preservation material. The spiral fireproof valve can be attached with thermal insulation material and looks beautiful.

The smoke exhaust fire damper is mainly used for ventilation pipes and air conditioning systems, and is usually in a "normally open" state. The performance of the fire control valve at low cost is stable, and when the air temperature reaches 70 degrees, the valve is automatically closed by the fuse action inside the valve.

The smoke outlets and exhaust valves are mainly installed on the pipes of the exhaust system or installed at the suction outlets of the fire smoke exhaust fans, and are usually closed.



Main functions of smoke exhaust fire damper

There are two items of 3C fire damper product testing items: close reliability. In the ten closing operation, the 3C fire damper should be able to be shut off from the opening and closing operation in a flexible and reliable manner. All parts and components should have no obvious deformation, wear and other damage affecting the sealing performance. When the fire is shut down reliability, use alcohol lamp or other fire source to melt the 3C fire damper temperature sensor. After the action of thermo sensor, the 3C fire valve should be automatically shut down and reliable shut down, including: the 3C fire damper automatically closes; the 3C fire valve automatically closes; the gap between the blades or between the blade and the baffle is not more than 2 millimeters.

The smoke exhaust fire damper is not an independent smoke prevention and fire product in the actual project, but has its unique linkage logic relationship in the whole fire linkage control system. Therefore, in order to ensure its function in the fire fighting system, the system must be adjusted according to the linkage requirements before the system is checked and accepted, so that ventilation, air conditioning and smoke control systems meet the standard requirements. After acceptance, there should be a dedicated person to carry out planned daily maintenance and management so as to ensure that the valve body is in normal condition and play its role in preventing smoke and fire.

In the air supply system, the wind sent by the blower must be distributed through the main pipe to the branch pipe. In the smoke extraction system, the flue gas is discharged from the branch pipe to the main pipe and then enters the smoke exhausting fan. When fire occurs in buildings and in ventilation and air conditioning systems, in order to prevent the fire from spreading through the air supply system, when the gas temperature in the air supply system reaches 70, the long-term supply of 280 degree fire damper is cheap, and the fuse on the fire damper mechanism acts, and the valve also rapidly closes the valve, cutting off the passage of the flue gas and the fire spreading along the wind pipe. Similarly, in the smoke exhaust system, when the fire occurs, the smoke valve opens, and the smoke is discharged. In order to cut off the flow of the high temperature flue gas in the exhaust pipe line and prevent the fire from spreading to another fire compartment, when the exhaust gas temperature reaches 280, the valve of the fireproof valve and the fume on the smoke outlet of the Yibin fire damper must be automatically closed to stop the smoke exhaust. It can be seen that the fire prevention valve and smoke exhaust valve have achieved the general principle, which is the function of smoke isolation and fire suppression.






The smoke exhaust fire damper is a fire-fighting component installed on the pipe of the mechanical exhaust system. Its main material is carbon steel, galvanized sheet and stainless steel. The function of smoke exhaust fire valve is actually closed when the temperature reaches 70 degrees, and it can meet the requirements of smoke leakage and fire integrity in a certain period of time. In daily life, it is also important to maintain and maintain smoke exhaust valves.



Fire damper is installed on the ventilation and air conditioning system of the delivery and return air pipe, usually open state, when the fire gas temperature when the pipe reaches 70oC, automatically shut down, in a certain period of time to meet the requirements of fire stability and fire integrity, smoke blocking fire role.
