Fire Damper Blade

The important role of fire damper blades and exhaust valves in ventilation, air conditioning and smoke control systems


Fire damper blades include gravity fire damper blades, fire control valves, fire vents, pneumatic fire damper blades, smoke dampers, electronic self-control smoke and fire damper blades, etc.; smoke exhaust valves include smoke venting valves, panel exhaust vents (ceiling Use), shaft exhaust outlets and other products. fire damper blades and exhaust valves are important components in ventilation, air conditioning and smoke control systems. The main functions played in the system are as follows:


In the air supply system, the wind sent by the blower must be distributed to the branch pipe through the main pipe; in the exhaust system, the flue gas is discharged from the branch pipe to the main pipe and then enters the exhaust fan. When a fire occurs in a building, in the ventilation and air conditioning system, in order to prevent the fire from spreading through the air supply system, when the gas temperature in the air supply system reaches 70 ° C, the fuse on the fire damper blade mechanism acts, and the valve also closes the valve quickly. Cut off the passage of smoke and fire along the duct. 


Similarly, in the smoke exhaust system, when a fire occurs, the exhaust valve is opened to exhaust smoke, in order to cut off the high temperature flue gas flowing in the exhaust pipe, preventing the fire valve from spreading to another fire zone, when the exhaust gas is discharged When the temperature reaches 280 °C, the smoke damper and the fuse on the exhaust vents act, and the valve must be automatically closed to prevent smoke exhaust. It can be seen that the fire damper blade and the exhaust venting valve have achieved the general pass, and the broken fire escapes the fire.
