Smoke exhaust fire damper is a fire-fighting component, which will be opened to exhaust smoke in case of fire. It is made of galvanized sheet, carbon steel or stainless steel, and its corrosion resistance is relatively strong, so it can be used for a long time. Smoke exhaust valves with decorative openings and decorated ones are smoke exhaust openings. So what are the differences between smoke exhaust valve and smoke exhaust fire valve?

1. Different installation positions: the fire damper is installed on the pipeline of ventilation and air conditioning system, which is usually open, and closed when the flue gas temperature in the ventilation pipeline reaches 70℃ in case of fire, and can meet the requirements of smoke leakage and fire integrity within a certain period of time, thus playing the role of smoke isolation and fire resistance. Generally, it consists of valve body, blade, actuator and temperature sensor. Smoke exhaust fire damper is installed on the pipeline of mechanical smoke exhaust system, which is usually open, and closed when the smoke temperature in the smoke exhaust pipeline reaches 280℃ in case of fire, and it can meet the requirements of smoke leakage and fire integrity within a certain period of time, and plays a role in smoke isolation and fire resistance. Generally, it consists of valve body, blade, actuator and temperature sensor.

2. The protection objects are different: the fire damper protects the people in the room where there is no fire, and the smoke exhaust fire damper protects the people in the room where there is fire. The fire damper is always open on the pipeline, or it is always open for a long time. When it is ventilated, it will automatically close when it catches fire. When the smoke in the normally closed room reaches a certain concentration, it will automatically open.

3. The smoke exhaust fan belongs to the smoke control system in the fire protection system, which is generally linked with the fire alarm host. The smoke exhaust fire damper is normally open, and it is also open in case of fire. However, when the smoke temperature reaches 280℃, the smoke exhaust fire damper will automatically close, and the fan that has been opened will stop running.
