Abstract

PURPOSE:To improve the water sealing effect by fitting a buffer ring onto the inner peripheral groove bottom surface of a sheet metal and allowing the center of the sheet metal of a valve box and the center of the sheet metal of a valve body to coincide with each other. CONSTITUTION:A sheet metal 3 whose inner peripheral surface 3a is inclined by theta in the axis center direction of a valve box B, keeping a certain lateral width, is installed in the inner periphery of the valve box B which forms the outer peripheral surface side of a valve body A. A pressing plate 8 is fixedly installed onto the edge surface side periphery of the valve body A which forms the part corresponding to the sheet metal 3, and a sheet metal 2 having a curved outer peripheral surface 2a is fitted in shiftable ways into the peripheral groove 1. A buffer ring 5 which has a nearly C-shaped section having a slit is fitted onto the outer peripheral surface. When a fluid pressure is applied, the center 01 in the lateral width direction of the sheet metal 3 and the center 02 in the lateral width direction of the sheet metal 2 coincide, and sure sealing performance can be secured.
