Smoke damper means mounted on the exhaust system pipe, usually was turned on, when the gas pipeline fire when the temperature reaches 280oC automatically shut down in a certain period of time to meet the fire resistance stability and fire integrity requirements. Role play the role of smoke fire retardant fire damper valve air exhaust system of a complex, intricate piping. In the air supply system, the blower wind sent to the main channel must be assigned to each branch through the tube; in ventilation or exhaust system, wind or smoke pooled by the branch after the main channel into the exhaust fan discharge. So, whether it is air system or exhaust system, if there is no barrier, then, Wuhan fire dampers, air supply and smoke can not control, no air or exhaust parts of a large number of air supply, exhaust situation, and need air or exhaust air is not part of, or just a small amount of exhaust air, exhaust. In order to not require air, exhaust parts of the pipeline cut Wuhan damper, which requires the valve means. Ventilation and air conditioning system, damper settings and the choice of (1) at the duct through the fire zone; (2) through the ventilation, air conditioning and major engine room fire hazard or a large wall and floor of the room (3) vertical wind pipe and each level of the horizontal pipe junction duct damper should be located, but each fire district multi-story building its ventilation and air conditioning systems are set up independently, then the horizontal and vertical duct manifold junction of the fire sub-region not to set fire damper professional Wuhan damper, Wuhan Han Wei Li Yuen (online consultation), Wuhan Wuhan Han Wei Li Yuen damper is provided by heating Equipment Co.
