Abstract
The utility model discloses an abrasion resistant eccentric hemisphere valve, which comprises a valve body and a hemispherical valve core. An inflow port and an outflow port are formed on two sides of the valve body respectively, an upper half shaft is rotationally mounted on the top of the valve body, a lower half shaft is fixedly and internally mounted inside the bottom of the valve body, the lower end of the upper half shaft is fixedly connected with the hemispherical valve core, and the upper end of the lower half shaft is fixedly connected with the hemispherical valve core. The abrasion resistant eccentric hemisphere valve has the advantages of simple structure, convenience in mounting and use and high operating efficiency, meanwhile prolongs the service life and improves the economic benefit, and therefore has a wider range of application.
Description
Technical field
The utility model relates generally to pipeline control valve door field, relates in particular to a kind of wear-resisting type eccentric half-ball valve.
Background technique
It is a lot of to work the ball valve kind of blocking medium in pipeline, hard seal eccentric ball valve and soft seal wear-resisting type eccentric half-ball valve are arranged, the sealing of hard sealing wear-resisting type eccentric half-ball valve is a 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 wear-resisting type eccentric half-ball valve is a metal pair rubber, the long-time back phase-contact surface that uses can the phase mutual friction, sealing can reach zero leakage, though existing in the market soft sealing structure reaches the effect of zero sealing in use, but its complex structure, the installation and maintenance inconvenience, particularly slightly use in the environment in the evil that fouling takes place easily, because of the generation of scale formation has influence on the unlatching freely of valve, reduced working efficiency, influenced 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 wear-resisting type eccentric half-ball valve is provided, complex structure, installation and maintenance inconvenience have been solved, have influence on the unlatching freely of valve because of the generation of scale formation, inefficiency, influence the problem of working life and economic benefit, dwindled the application area of valve.
The utility model is achieved through the following technical solutions:
A kind of wear-resisting type eccentric half-ball valve, include spherical valve body, hemisphere spool, the both sides of described valve body are respectively equipped with inflow port, go out head piece, it is characterized in that: described valve body top is rotatablely equipped with semiaxis, described valve body is rotatablely equipped with down semiaxis in the bottom, last semiaxis, following semiaxis are fixedlyed connected with the hemisphere spool respectively, and spool and inflow port fitting surface are provided with wearing layer.
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 soft sealing structure respectively between hemisphere spool and valve flowing channel one side, make that the 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 of not using the unlatching freely of breaking down or having influence on valve because of the generation of scale formation for a long time.
Advantage of the present utility model is as follows:
The utility model is simple in structure, easy to install, high working efficiency, has improved working life and economic benefit simultaneously, makes that the application area of this type of valve is more extensive.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of wear-resisting type eccentric half-ball valve, include spherical valve body 1, hemisphere spool 2, the both sides of valve body are respectively equipped with inflow port 3, go out head piece 4, the valve body top is rotatablely equipped with semiaxis 5, valve body is rotatablely equipped with down semiaxis 6 in the bottom, and last semiaxis, following semiaxis are fixedlyed connected with the hemisphere spool respectively, and spool and inflow port 3 fitting surfaces are provided with wearing layer 7.
