Product Description

Fire damper: installed in the ventilation, air conditioning systems to send, the road back to the wind, usually was turned on, fire when the pipeline reaches 70 ℃, gas temperature, fusible film fuse, the torsion spring force the valve to automatically shut down in a certain period of time to meet the fire resistance stability and fire integrity requirements, the role of the fire fight from the valve. Valve is closed, the output off signal.

Installed central air-conditioning duct system, the working principle is the temperature of the fusible alloy membership control, the use of gravity and the role of spring mechanism to close the valve. When a fire occurs, the flame duct invasion, high temperature so that the valve on the fusible alloy melting, or deformation of the shape memory alloy produced automatically close the valve for the air duct and the fire district through the occasion.
