Anonymous users2024-01-23The check valve for the kitchen flue is only opened when the flue is ventilated, and closed when the air is not discharged.
Now the flue check valve basically does not need to be disassembled and cleaned, there is a wind plate with a certain inclination angle that rotates very flexibly in the check valve, and there is a silicone sealing ring on the side of the wind plate, and the sealing performance is very good. The fan plate is closed when the range hood is not in use, and the wind plate is turned on when the range hood is open when there is wind pressure.
It cannot be demolished, but the top and bottom floors can be demolished, subject to the consent of the property.
Plastic aluminum is generally used.
It is estimated that it is used for natural gas water heaters, and now few people use flues, all of which are directly punched in the wall, and high-rise houses are not estimated to be punched?
1. The exhaust outlet of the exhaust fan in all kitchens is drilled two meters high, which will not be short, and it is completely okay.
