There are some buildings in fire protection engineering projects to reuse these devices circumstances. Such as Chongqing Tobacco Building is an example. Automatic tobacco smoke damper Chongqing mainly office and commercial buildings, walkways long damper, set the mechanical exhaust system, each floor is only a smoke partition. Smoke on each floor electric charge of the design of a normally closed damper, each of each exhaust port has designed an electric normally closed exhaust valves, exhaust fan inlet of the fire has designed a normally closed electric smoke damper. Obviously Wuhan fire control valve, the existence of this design feature Wuhan smoke damper wholesale waste, but also modules, valves, construction costs of waste. Damper sub 70 degrees and 70 degrees is 280 degrees Wuhan damper automatically closes when the temperature reaches 70 degrees procurement, then the input module when the temperature reaches 280 degrees is 280 degrees off automatically connect input and output modules, to be coordinated shutdown. Wuhan price smoke damper, damper, Wuhan Han Wei Wei Li Yuen provided by Wuhan Han Liyuan heating equipment Limited. Wuhan Han Wei Li Yuen-being of Equipment Co., Ltd.
