Fire dampers can be divided into various structures according to their functions, such as smoke exhaust valves, smoke exhaust fire dampers, fire control valves, smoke and fire control valves, etc.

a, Smoke exhaust valve

Smoke exhaust valves are installed on the pipelines of smoke exhaust systems in high-rise and underground buildings. Their basic functions include: temperature sensing (smoke) electrical signal linkage, and simultaneous operation of smoke exhaust fans; Manually open the valve and start the smoke exhaust fan simultaneously; Output valve opening signal.

b, Smoke exhaust fire damper

The smoke exhaust fire damper is installed on the smoke exhaust system pipeline that meets the requirements of smoke exhaust and fire prevention (located on the pipeline at the suction inlet of the smoke exhaust fan). Its basic function is not only to function as a smoke exhaust damper, but also to fuse when the smoke exhaust temperature exceeds 280 ℃, causing the valve to close and the smoke exhaust fan to stop at the same time.

c, Fire control valve

The fire control valve is installed on the ventilation and air conditioning system pipeline with fire prevention requirements (to prevent the spread of fire along the air duct). Its functions include: the temperature fuse melts at 70 ℃, causing the valve to close; Output valve closing signal, causing the ventilation and air conditioning system fan to shut down; Stepless adjustment of air volume.

d, Smoke and fire control regulating valve

The smoke and fire prevention regulating valve is installed on the ventilation and air conditioning system pipeline with smoke and fire prevention requirements (to prevent the spread of smoke and fire). Its functions include: the linkage of smoke (temperature) electrical signals to close the valve and stop the ventilation and air conditioning system fan; Manually close the valve and stop the fan; The temperature fuse melts at 70 ℃ to close the valve; Output valve closing signal; Adjust the air volume in stages of 90 ° five equal parts
