Pressure plate flexible connection type self-cleaning valve clack

Abstract

The invention discloses a pressure plate flexible connection type self-cleaning valve clack. The pressure plate flexible connection type self-cleaning valve clack comprises a valve clack head and a valve rod, wherein the valve rod has a structure which is used for motion guide and is connected with a driving part, and comprises a first rod section and a second rod section; the first rod section is integrally formed on the valve clack head; the second rod section is used for motion guide and is connected with the driving part; the first rod section is hinged to the second rod section through a spherical hinge connector structure; optimally, the spherical hinge connector structure comprises a first half ball socket, a ball head and a half ball cap with a second half ball socket; the first half ball socket is formed on the first rod section; the ball head is formed at the front end of the second rod section through a ball head shaft neck; the half ball cap is arranged inside a thread cap; the thread cap is mounted on the ball head shaft neck in a sleeving manner; the thread cap is screwed on the first rod section; and the half ball cap comprises at least two halves which are equally divided circumferentially. The pressure plate flexible connection type self-cleaning valve clack has the beneficial effects that a valve with the valve clack has a self-cleaning function, the structure is simple, the processing is convenient, the reliability is good, the service life is long, and the maintenance is convenient.

Description

technical field [0001] The patent of the present invention relates to a valve component, in particular to a pressure plate union type self-cleaning valve disc. Background technique [0002] In the cut-off valve or pressure regulating valve, the disc is used to block the valve port of the gas circuit, and the front end of the disc is provided with a gasket, which is usually sealed by the gasket on the end face. In order to ensure the sealing effect, the end face of the valve port and the surface of the sealing gasket are required to have a high degree of cleanliness. Before the valve is installed, cleaning is usually required to ensure its cleanliness. However, during the working process, because the dust in the gas is easy to accumulate on the sealing surface, especially some electrostatically charged dust is more likely to accumulate on the soft non-metallic gasket, which affects the sealing effect. In order to ensure the stable sealing effect of the valve for long-term us...
