流弁。 A ring-shaped valve part provided at the opening at the downstream end of the water flow iron pipe, a conical valve body that is movable in the axial direction and moves toward and away from the valve part, and the valve part and the valve body. A discharge valve is constituted by a cylindrical hood that covers the water flow iron pipe, and the water flowing in from the water flow iron pipe is guided to the outer peripheral wall surface of the valve body together with the outside air taken in from the air supply port provided at the upstream end of the cylindrical hood. In the hooded discharge valve, the jet flow becomes a jet flow while flowing through the cylindrical hood, and is then discharged to the outside. The contact angle between the inner surface of this conical hood and the back surface of the jet stream is set to be around 10 degrees, and the inner periphery of the opening at the tip of the conical hood and the outer periphery of the water flow iron pipe passing through this opening are made to be approximately 10 degrees. A hooded discharge valve characterized by forming a gap as an air supply port.
