Smoke dampers, fire protection components, typically installed in the pipe mechanical exhaust system, usually was turned centrifugal wind chassis, fire when the internal temperature reaches close the flue gas exhaust pipe 280 degrees, and at a certain time to meet leakage smoke and fire integrity requirements of low noise cabinet centrifugal wind chassis, from smoke fire retardant effect. Main material: carbon steel, galvanized steel, stainless steel. 1. Purpose (1) usually in a normally closed valve, either manually or automatically open fire, when the airflow temperature reaches 280 ℃, the temperature sensor action, the valve is closed; (2) allows the valve is closed by DC24V power; (electric type smoke damper) (3) or manual reset manually shut down; (4) closed DC24V electric reset; (automatic type smoke damper is suitable for manual operation inconvenient places) (4) signal output valve closed, with Other fire safety interlock device. Advantages: 1, low air leakage, airtight performance 2, the electric current consumption of small Pacific open exhaust valve exhaust valves ★ Product description applies generally installed on the exhaust duct system, usually normally closed, when the fire. smoke detector alarm signals issued by the control center to turn on electrical solenoid valve opens the valve quickly, you can manually open the valve quickly exhaust.
