 Smoke damper: exhaust system installed in the pipeline, the general was usually closed, manual or electric fire smoke damper open manually, from the smoke in the exhaust pipe when the role of the flue gas temperature reaches 280 ℃ closed. Its electric exhaust opening function is usually caused by the control center or simply smoke detection devices to command their movements. Simply put: fire control valve is normally open under normal conditions, the wind pipe temperature exceeds set to close the valve to prevent the spread of fire; smoke damper important role in ventilation, air conditioning and smoke control systems in the air supply system, the blower wind sent through the main pipe must be allocated to the branch pipe; in the exhaust system, the flue gas from the manifold to the main pipe, into the exhaust fan discharge. When a fire broke out in the building, ventilation, and air conditioning systems rectangular smoke damper, in order to prevent the fire from spreading through the air supply system, gas supply system when the temperature reaches 70 ℃, the damper mechanism fuse action, the valve also quick off valve, cut off the duct smoke and fire spread along the pathways. Similarly, in the exhaust system, the case of fire, smoke exhaust valve opens remote smoke damper, smoke smoke damper conduct, in order to cut off the flow of high temperature gas in the exhaust pipe to prevent the fire from spreading to another fire partition, when the exhaust flue gas temperature reaches 280 ℃, smoke damper on the exhaust port fuse action, the valve must be automatically shut down to prevent smoke. Thus, fire dampers, exhaust valves so that the general rule pass, which is broken off smoke fire retardant effect.
