Categories; dampers installed in the ventilation, air conditioning system, the return air duct on the road, usually was turned on, the gas pipeline inside when the temperature reaches 70 ℃, fire dampers brand, fusible film fuse how to use fire dampers, valves torsion force automatically shut down in a certain period of time to meet the fire resistance stability and fire integrity requirements, since the role of smoke fire retardant effect of the valve. When the valve is closed, the output off signal. Smoke fire control valve, normally open, 70 degrees closed, with 1, but more an electrical signal input, remote control can eliminate the control room is closed, generally used for peacetime air, fire up a common air duct system can be controlled fire Close unneeded makeup air rooms; damper is used to block the smoke and flames from the fire zone by, and within a certain period of time to meet the fire resistance stability and fire integrity requirements of the valve. When the building is on fire, the fire spread rapidly along the pipeline ventilation, air conditioning systems fire dampers introduced, resulting in significant loss of the case are many. In order to reduce the losses caused by the fire to a minimum, we must take effective fire prevention, smoke control measures to control the spread of fire, and a reasonable set of dampers in ventilation, air conditioning and smoke control system, then played an important effect. However damper, in many design projects, dampers selection error, set the position irrational common occurrences.
