The role of this type of backdraft damper is to only allow the air to flow in one direction and prevent the flow in the opposite direction. Usually, this kind of valve works automatically. Under the action of the fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the self-coincident valve flap of the fluid pressure and the valve flap acts on the valve seat, thereby cutting off the flow.
