Embodiment Construction

[0008] A manufacturing process of a proportional pressure reducing valve mainly includes the following steps: a "Y" sealing ring is provided in the valve body. The structure of the proportional pressure reducing valve produced by the present invention will be further described in detail below in conjunction with the accompanying drawings. 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, which leads to the sensitive opening of the valve clack and the long service life of the sealing ring.

Abstract

The invention discloses a preparing craft of proportion type pressure reducing valve, which comprises the following steps: providing a 'Y' shaped seal ring in valve body; getting the product. This invention possesses reasonable craft and long durability, which can length the age of the seal ring.

Description

Technical field: [0001] The invention relates to a manufacturing technology of a valve, in particular to a manufacturing process of 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. The "O"-shaped sealing ring has the defects of high friction, no wear resistance and short service life during the working process, 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 manufacturing process of a proportional pressure reducing valve that can effectively overcome the above-mentioned defects, has a sensitive action and a long service life. [0004] The technical solution adopted by the present invention to solve the technical problem is a manufacturing process of a proportional pressure reducing valve, which mainly includes the follow...
