② Tobacco fire prevention valve.The parts and blades of the installation are the same as the smoke discharge valve. The difference is that it has the fire prevention function. When the temperature of the flue gas reaches 280 ° C, the leaves can be turned off by the temperature sensor or manually to cut off the gas source.
③ The remote control smoke discharge valve.It is installed on the duct or smoke exhaust mouth of the smoke exhaust system, which is usually closed.The fire alarm signal was issued during the fire, and the control center was powered on the electromagnets of the remote controller, causing the smoke exhaust valve to open, or manually open and reset the valve.
