Galvanized fire dampers, fire dampers, ventilation plant in Texas

Electric damper material is divided into: carbon steel, galvanized sheet. Electric fire damper is installed in the ventilation and air conditioning systems, the return air duct, usually was turned fire control valve, fire shut the pipeline when the flue gas temperature reaches 70 degrees, and in a certain amount of time to meet the leakage of smoke and fire integrity requirements, since the role of smoke fire retardant. (1) usually in a normally open valve galvanized damper, when the airflow temperature reaches 70 ℃, [1] heat detectors action, the valve is closed; (2) allows the valve is closed by DC24V power; (3) manually shut down or manual reset; (4) within the range of 0 ° ~ 90 ° manually adjustable vane opening degree (regulated); (5) the output signal of the valve is closed, can interlock with other fire-fighting equipment. The structural characteristics of electric smoke damper electric smoke damper usually normally closed damper, mainly installed in the duct exhaust system, in use in Texas l damper manufacturer, if a fire, then the control center through DC24V Telecommunications number to the solenoid valve, the valve opens quickly. After the body frame of the device with 2 mm galvanized sheet cold roll forming, with carbon dioxide gas welding or welding by ordinary Q235 plate processing; blades with 1 mm cold rolled galvanized sheet for corrugated, spot welding two pieces of synthetic interpolating axes, or 2 mm G235 steel cold forming, punching chip interpolating axes or welding circular shaft.
