Embodiment Construction

[0006] Referring to the accompanying drawings, the valve seat 5 is threadedly connected to the valve body 1, and the valve body 1 is provided with "Y"-shaped sealing rings 2 and 3, and a piston-shaped valve disc 4 is arranged inside the "Y"-shaped sealing ring. Due to the use of "Y" shaped sealing ring, the friction force is effectively reduced and the wear resistance of the sealing ring is improved, so that the valve disc can be opened sensitively and the sealing ring has a long service life.

Abstract

A pressure release valve of proportion type is composed of valve body, seal washer, piston shaped valve clack and valve base. It features that some internal bushes of valve body are set to be Y shaped seal washer to decrease frictional force effectively and to increase service life of said valve effectively.

Description

Technical field: [0001] The present invention relates to a valve, in particular to a pressure reducing valve. Background technique: [0002] In the existing proportional pressure reducing valve, the valve body and the disc adopt "O"-shaped sealing rings. "O"-shaped sealing ring, in the working process, has the defects of high friction, not wear-resistant, and short service life, which leads to insensitive opening of the valve disc and short service life. Invention content: [0003] The technical problem to be solved by the present invention is to provide a proportional pressure reducing valve which can effectively overcome the above-mentioned defects, has sensitive action and long service life. The technical solution adopted by the present invention to solve the technical problem is a proportional pressure reducing valve, which is mainly composed of a valve body, a sealing ring, a piston-shaped valve disc and a valve seat. Y" shaped seal. Due to the adoption of the abov...
