What is the function of the ventilator's check valve?
When the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
The utility model relates to a flue check valve, which belongs to an automatic valve, and the main function of the utility model is to prevent the backflow of oil smoke, and only to flow in one direction, and to block gasFlow in reverse direction. When the soot exhauster starts to work, the air flow with the oil smoke pushes the one-way smoke valve through the air inlet and the flow guiding curved surface, and the soot is discharged into the public smokeWhen the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
The flue check valve refers to the automatic opening and closing valve plate, which is used to prevent the backflow of soot through the thermal flow of the range hood. It is also called the smoke back valve, the smoke prevention treasure and the flue isolator.
