Embodiment Construction

[0006] Referring to the accompanying drawings, the piston-shaped valve disc body 4 is connected with the diversion cap 1 through the connecting bolt 5, and the piston-shaped valve disc body 4 is embedded with a gasket 3 to form a seal with the fixed sleeve. Wherein, the middle part of the piston-shaped valve disc body 4 is provided with a "Y"-shaped sealing ring 2, which effectively reduces the friction force, thereby causing the valve disc to open sensitively.

Abstract

A piston shaped valve clack with Y form seal washer is composed of piston shaped valve clacks body and flow guide cap. It features that Y form seal washer is set at middle part of piston shaped valve clack body to form sealing with fixed bush, Y form seal washer is applied to decrease frictional force effectively so as to increase service ¿C life of seal washer.

Description

Technical field: [0001] The present invention relates to a valve, in particular to a disc of a valve. Background technique: [0002] In the existing piston-shaped valve clack, the middle part of the piston-shaped valve clack body is provided with an "O"-shaped sealing ring. "O"-shaped sealing ring, in the working process, has the defects of high friction and not wear-resistant, which leads to insensitive opening of the valve disc and short service life of the sealing ring. Invention content: [0003] The technical problem to be solved by the present invention is to provide a piston-shaped valve clack provided with a "Y"-shaped sealing ring, which can effectively overcome the above defects, has low power loss and long service life. The technical solution adopted by the present invention to solve the technical problem is that a piston-shaped valve disc with a "Y"-shaped sealing ring is mainly composed of a piston-shaped valve disc body and a diversion cap, and its character...
