Abstract
PURPOSE:To reduce the impact pressure at the time when cavitation bubbles break by constituting a valve so that the inside of the valve body is formed so as to narrow the stream to the direction of flow, and that the valve seat is formed so as to be opened to the direction of flow. CONSTITUTION:A cylindrical wall 10 is projected from the end surface periphery on the valve seat 3 side of a valve body 1 so that the inner circumferential part 10a thereof is formed by a taper surface with a bell shape toward the valve seat 3, and a cylindrical wall 11 is projected from the periphery of the passage hole 4 on the valve body side 1 of the valve seat 3 so that the outer circumferential part 11a thereof is formed by a taper surface with a bell shape toward the valve body side. Thus, compared with the conventional structure, the rethrottled part (b) where the pressure drop is maximum can be kept apart from the throttle part (a) being narrow in dimensions by the streamline (c) from above which, passing through the inside of a trapezoidal recessed part, flows into the throttle part (a), enabling the differential pressure at the throttle part (a) to be reduced.
