I believe everyone is familiar with the smoke exhaust fire damper. Its appearance has been favored by a wide range of people. Do you know what applications it has in life?

Whether the smoke exhaust fire damper is normally open or normally closed should be determined according to the form of smoke exhaust port. When a normally closed smoke exhaust port is set, the smoke exhaust branch pipe is provided with a normally open smoke exhaust fire damper. When a normal open tuyere is set, a normally closed smoke exhaust fire damper should be set on the smoke exhaust branch pipe. When a normally closed fire-proof smoke outlet is provided, the smoke exhaust branch pipe should not be provided with a smoke exhaust fire valve. In the basement with mechanical smoke exhaust, air intake facilities should be considered. When mechanical air intake system is adopted, a 70℃ fused fire damper should be set on the fan inlet pipeline. For the mechanical pressurized air supply system, a 70℃ fused fire damper can be set on the inlet pipe of the pressurized air blower to prevent the fresh air inlet from being threatened by fire and smoke and transport the smoke to the floor.

Smoke exhaust fire dampers are widely used in fire sprinkler systems. Customers should pay attention to some matters in the process of application. If this kind of situation is ignored, it will cause unnecessary inconvenience to the operation of smoke exhaust fire damper in the second half of the year. Smoke exhaust fire damper has the characteristics and application scope of the transported gas.

The exhaust fan shall ensure continuous operation for 30 minutes at 280℃. It should be noted that the smoke exhaust fire damper should be set in front of and behind the smoke exhaust fan, which should be determined flexibly according to the specific situation. Take the smoke exhaust system in the basement as an example. When the basement is only one floor, and the smoke is discharged to the outside through the vertical duct, the smoke exhaust fire damper should be set on the main pipe at the entrance of the smoke exhaust fan. When the basement floors are on the second floor and above, and each floor shares a smoke exhaust shaft, the smoke exhaust fire damper on each floor should be set above the outlet manifold of the smoke exhaust fan, that is, close to the side of the smoke exhaust shaft. Whether it is a vertically arranged walkway smoke exhaust system or a horizontally arranged room smoke exhaust system, a smoke exhaust fire valve that can automatically close at 280℃ should be set at the joint between the smoke exhaust branch pipe and the vertical air duct.
