When the valve is closed, the output sent off signal fire control valve dampers installed in ventilation and air conditioning system, the return air duct on the road, usually was turned on, when a fire in the pipeline when the gas temperature reaches 70 ℃, fusible film fuse, valve torsion force automatically shut down in a certain period of time to meet the fire resistance stability and fire integrity requirements, from the effects of smoke fire retardant across the valve. When the valve is closed, the output signal is turned off. Smoke damper: exhaust system installed in the pipeline, the general was usually closed, manual or electric opened fire, smoke from the fire blower role htfc | Anhui Blower | Chizhou Fire fan from Shandong GREAT fan air conditioning equipment.
