Embodiment Construction

[0008] A sensitive opening technology of a piston-shaped valve clack mainly includes the following steps: a "Y"-shaped sealing ring is provided in the middle of the piston-shaped valve clack body. The structure of the piston-shaped valve clack produced by the present invention will be further described in detail below in conjunction with the accompanying drawings. 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, which effectively reduces the friction force, thereby causing the valve disc to open sensitively.

Abstract

The invention discloses a keen opening technique of piston shaped valve clap, which comprises the following steps: providing a 'Y' shape seal ring in middle of the piston shaped valve clap; getting the product. This invention possesses reasonable craft and good idea, which can length the age of the seal ring.

Description

Technical field: [0001] The invention relates to a valve manufacturing technology, in particular to a sensitive opening technology of a valve 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 sensitive opening technology of a piston-shaped valve clack which can effectively overcome the above defects, has small power loss and long service life. [0004] The technical solution adopted by the present invention to solve the technical problem is a sensitive opening technology of a piston-shaped valve flap, which mainly includes the follow...
