Swing type check valve

Abstract

Abstract PURPOSE:To cause rapid seating of a valve body to a valve seat and to improve response by a method wherein the valve body of a swing type check valve body is supported in a position deviated from a center of gravity to the downstream side. CONSTITUTION:A valve body 1 of a swing type check valve is mounted in a valve box 8 in a manner to be slightly inclined at an angle of beta with a direction extending at right angles with an axis line M. The valve body 1 is rotatably supported in a position deviated to the downstream side from a center of gravity by means of valve body support axles 4 and 5 having an inclination angle beta. This constitution exerts a couple in a valve closing direction on the valve body 1 and in positions around the valve body support axles 4 and 5.
