3C smoke exhaust fire damper achieves the effect of fire blocking and smoke exhaust!

   3C smoke exhaust fire damper consists of a casing, blades and a rotating shaft. The rotating shaft is installed on the casing, and an expanding sealing block is fixed on the rotating shaft. The expanding sealing block consists of a sealing block, a spring pressure plate and a top block. Through the expanding sealing block, while ensuring the expansion allowance of the blade when heated, the sealing performance when the 3C smoke exhaust fire damper manufacturer closes is ensured. It should be installed in the duct section close to the wall or floor slab. The fire damper on both sides of the fire compartment partition wall should not be greater than 200mm from the wall surface, and the pipes and their insulation materials within 2.0m on both sides of the fire damper should be made of non-combustible materials.

   The 3C smoke exhaust fire damper should be provided with independent supports and hangers to avoid pipeline deformation affecting its performance during a fire. The fusible link of the Shandong 3C smoke exhaust fire damper should be installed on the side facing the greater fire risk. The operation side of the 3C smoke exhaust fire damper valve should have a clear space of not less than 200mm for maintenance. Before installing the valve, it is necessary to check whether the valve's operating mechanism is intact and whether the action is flexible and effective. The 3C smoke exhaust fire damper achieves the effect of fire blocking and smoke exhaust. When the fire causes the air duct to reach a certain temperature, the fusible piece melts, and the valve plate originally connected by the fusible piece is immediately disengaged from the fusible piece and closed to block the airflow.

    To ensure the actual effect of the application of the 3C smoke exhaust fire damper, waterproof and rainproof measures should be taken during the application of the smoke exhaust fire damper, and the dirt and dust inside the smoke exhaust fire damper should be frequently removed during normal times. The valve body of the 3C smoke exhaust fire damper is composed of a casing, flange, blades and blade linkage mechanism, while its actuator is composed of a casing, blade adjustment mechanism, clutch, temperature fuse, etc.
