Abstract
The invention discloses an eccentric semi-spherical valve, which comprises a valve body and semi-spherical valve cores, wherein the lateral surface of the valve body is provided with a flow inlet and a flow outlet; the top part and the bottom part of the valve body are provided with a bearing block respectively; an upper shaft sleeve is fixedly arranged in the bearing block on the top part of the valve body; an upper half shaft is rotatablely arranged in the upper shaft sleeve; a lower half shaft is fixedly arranged in the bearing block on the bottom part of the valve body; one end of the lower half shaft extends into the valve body, and an extended end is rotatablely provided with a lower shaft sleeve; the upper half shaft and the lower half shaft are in sealed matching with the bearing blocks, and corresponding ends of the upper half shaft and the lower shaft sleeve are fixedly provided with a semi-spherical valve core respectively; and the semi-spherical valve cores are positioned on a flow passage between the flow inlet and the flow outlet of the valve body, and are in sealed matching with one side of the flow passage of the valve body. The eccentric semi-spherical valve has a simple structure, is convenient to mount and use, has high working efficiency, and simultaneously prolongs the service life and improves economic benefits, so the type of the valve has a wider application range.
Description
Technical field
The present invention relates generally to pipeline control valve door field, relates in particular to a kind of 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 eccentric half-ball valve are arranged, the sealing of hard seal eccentric semi 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 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.
Summary of the invention
The objective of the invention is in order to remedy the deficiency of prior art, a kind of 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 present invention is achieved through the following technical solutions:
A kind of eccentric half-ball valve, include valve body and hemisphere spool, described side of valve body is provided with inflow port, go out head piece, the top and the bottom of described valve body are respectively equipped with bearing support, the bearing support internal fixation at described valve body top is equipped with Upper shaft sleeve, be rotatablely equipped with semiaxis in the described Upper shaft sleeve, the bearing support internal fixation of described valve body bottom is equipped with down semiaxis, a described end of semiaxis down stretches in the valve body, and external part is rotatablely equipped with Lower shaft sleeve, on described, be sealed and matched between following semiaxis and the bearing support, the described semiaxis of going up, the corresponding end of Lower shaft sleeve is installed with the hemisphere spool respectively, described hemisphere spool is positioned at the valve body inflow port, go out on the runner between the head piece, and cooperate with valve flowing channel one side sealing.
Adopt O type circle or seal ring sealing between described bearing and the bearing support, described hemisphere spool and valve flowing channel one side adopt seal ring, sealed pressing sleeve sealing.
Its working principle 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 not break down or holds shoulder freely because of what the generation of scale formation had influence on valve because of long-term the use.
Advantage of the present invention is:
The present invention 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
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
