Manufacturers explain the normally open smoke exhaust valve function!

Smoke fire dampers are generally installed on the pipes of the mechanical smoke exhaust system and are normally closed. When a fire occurs, the smoke is opened. When the flue gas temperature in the flue gas duct reaches 280 degrees, it is closed, and the amount of smoke leakage is met within a certain period of time. And fire integrity requirements, from the role of smoke and fire. Today, manufacturers will explain to you about the function of the normally open smoke exhaust fire damper. I hope to bring you help. Here's what we can learn about:

1. It is normally open at normal times. When a fire occurs, the valve automatically shuts off when the control center outputs DC24V power.

2. When the temperature of the pipeline reaches 280°C, the fuse operates and the valve closes automatically.

3, output valve closing signal, interlock smoke exhaust fan to stop.

4, manually closed, manually open.
