Abstract

The utility model discloses an anti-abrasion plate for an eccentric semispherical valve. The anti-abrasion plate comprises a ring body, wherein a step matched with a valve body is arranged at one end of the ring body, and a circular bearing plate matched with a spherical valve clack is arranged at the other end of the ring body. The anti-abrasion plate is simple in structure, convenient to mount and use and high in working efficiency; moreover, the service life is prolonged, and the economical benefit is improved; and therefore, the type of valve can be widely applied.

Description

A kind of eccentric half-ball valve wearing plate
Technical field
The utility model relates generally to pipe control valve field, relates in particular to a kind of eccentric half-ball valve wearing plate.
Background technique
In pipeline, work the ball valve kind of blocking medium a lot, hard sealed eccentric ball valve and soft seal eccentric half-ball valve are arranged, the sealing of hard seal eccentric semi ball valve is metal to metal, phase-contact surface meeting phase mutual friction after long-time the use, make and be sealed with certain leakage, the sealing of soft seal eccentric half-ball valve is metal pair rubber, phase-contact surface can the phase mutual friction after long-time the use, sealing can reach zero leakage, although existing soft sealing structure reaches the effect of zero sealing in use in the market, but its complex structure, installation and maintenance are inconvenient, particularly slightly use in the environment in the evil that fouling easily occurs, have influence on the freely unlatching of valve because of the generation of scale formation, reduced working efficiency, affected working life and economic benefit.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of eccentric half-ball valve wearing plate to be provided, and solved the problem of complex structure, installation and maintenance inconvenience, and the current water outlet is stablized smooth and easy more, guaranteed that long-term use needn't change.
The utility model is achieved through the following technical solutions:
A kind of eccentric half-ball valve wearing plate includes circle body, and an end of circle body has the step that is complementary with valve body, and the other end has the bearing plate of the circular arc that matches with globe disk.
The material of described circle body is wear-resistant material.
Working principle of the present utility model is to make valve unimpeded or inaccessible by rotary spool, simultaneously between upper and lower semiaxis and the bearing support and adopt respectively soft sealing structure between hemisphere spool and valve flowing channel one side, so that ball valve switch is light, sealing is reliable, sealing surface and the sphere closed state of being everlasting is difficult for by the medium erosion; And the connection between its each parts is simple, sealing, firm, can be because not using for a long time the freely unlatching of breaking down or having influence on valve because of the generation of scale formation.
Advantage of the present utility model is as follows:
The utility model is simple in structure, easy to install, high working efficiency, has improved simultaneously working life and economic benefit, so that the application area of this type of valve is more extensive, the current water outlet is stablized smooth and easy more, has guaranteed that long-term use needn't change.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of eccentric half-ball valve wearing plate includes circle body 1, and an end of circle body 1 has the step 2 that is complementary with valve body, and the other end has the bearing plate 3 of the circular arc that matches with globe disk, and the material of circle body 1 is wear-resistant material.

Claims (2)

1. an eccentric half-ball valve wearing plate includes circle body, it is characterized in that: an end of circle body has the step that is complementary with valve body, and the other end has the bearing plate of the circular arc that matches with globe disk.
2. eccentric half-ball valve wearing plate according to claim 1, it is characterized in that: the material of described circle body is wear-resistant material.
