Abstract

PURPOSE: To reduce noise generated by opening and closing of a valve as well as lessen the flow resistance by opening and closing the valve opening with valve element made of elastic material, in compliance with the pressure of fluid.
CONSTITUTION: A valve seat 4 is constructed by such a procedure as surrounding the periphery of the base 1 having a flat face, with a circumferential wall 2 having an end, at the opposite side to the base 1, aslant with respect to said flat face 10 of the base 1 and forms thereby a ring-shaped valve opening 3 between the base 1 and circumferential wall 2. A valve element 5 is fixed with its central part to said flat face 10 of the base 1 so that its periphery makes elastic contact with said slant end surface 12 of the circumferential wall 2 and that the valve opening 3 is thereby covered with possibility of easy opening. When the rate of flow in the valve opening 3 is small, the valve element 5 opens only at Point B and, with increase of the rate of flow, it open at Point A, D one after another to lead to the maximum opening when it opens at Point C. Thus, the opening degree of valve opening 3 is controlled in accordance with the rate of flow, and stabilized flow with minimized flow loss can be obtained.
