Fire damper is installed in the ventilation, 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, Wuhan exhaust valve automatically closes under torsion force Wholesale dampers, within 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 damper wholesale Wuhan quality output off signal. Companies with good management, perfectly elegant working environment, gathered a group of high-quality marketing and R & D personnel. Faced with the growing market of high-tech smoke damper Wuhan price for the company to better development and survival, the company will continue to discover and develop new products. Now the company has with Germany Ke resistant Vladimir (okonoff) company, Prairie Hill (PRESSURE) Corporation, Shanghai Seahawks Machinery Factory signed a cooperation agreement damper, and became the distributor of the three companies in Hubei Province. 1. The construction and installation of fire dampers with fan, exhaust fan interlock. 2. The operation of the valve mechanism side should be not less than 200mm of headroom to facilitate maintenance. 3. The valve must be checked before installation of the valve operating mechanism is intact, the action is flexible and effective. The damper should be installed in the duct segments close to the wall or floor, the fire dampers on both sides of the partition wall from the wall surface should not exceed 200mm, dampers and pipe insulation material on both sides of each 2.0m wide should be non-combustible material. 5. The damper should set up a separate hanger to prevent pipe deformation affecting its performance in case of fire. 6. damper fuse should be installed in a large piece of the side facing the fire risk.
