Fire dampers, normally open, close at 70 ° C or 280 ° C, are generally installed at the locations where air ducts pass through firewalls and structural deformation joints to control fires. They can be set to output electrical signals, and when the temperature exceeds 70 ° C or 280 ° C, the valve will close, and the linked supply (supplement) fan will close.
The fire damper is installed in the central air conditioning duct system, and its working principle is to use the temperature control of the fusible alloy installed on the valve. With the action of gravity and spring mechanism, when a fire occurs, the flame invades the duct, and the high temperature melts the fusible alloy on the valve, or causes the memory alloy to deform and automatically close the valve. It is used in situations where the duct passes through the fire compartment.
