Abstract

The utility model discloses an eccentric semi-ball valve, which comprises a valve body and a semispherical valve spool. A flow inlet and a flow outlet are respectively arranged on two sides of the valve body, an upper half shaft is rotatably installed on the top of the valve body, a lower half shaft is fixedly installed at the inner bottom of the valve body, the lower end of the upper half shaft is fixedly connected with the semispherical valve spool, and the upper end of the lower half shaft is fixedly connected with the semispherical valve spool. The eccentric semi-ball valve is simple in structure, convenient in installation and use and high in working efficiency, prolongs service life, increases economic benefits, and more widens application range of similar valves.

Description

Eccentric half-ball valve
Technical field
The utility model 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.
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 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 eccentric half-ball valve, include valve body and 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 bottom internal fixation is equipped with down semiaxis, fixedlying connected with the hemisphere spool in the lower end of last semiaxis, fixedlys connected with the hemisphere spool in the upper end of following semiaxis.
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
Accompanying drawing 1 is the utility model structural representation.
Embodiment
A kind of eccentric half-ball valve, include valve body 1 and hemisphere spool 2, the side of described valve body 1 is provided with inflow port, go out head piece, the top of described valve body 1 and bottom are respectively equipped with bearing support 3, bearing support 3 internal fixation at described valve body 1 top are equipped with Upper shaft sleeve 4, be rotatablely equipped with semiaxis 5 in the described Upper shaft sleeve 4, bearing support 3 internal fixation of described valve body 1 bottom are equipped with down semiaxis 6, a described end of semiaxis 6 down stretches in the valve body 1, and external part is rotatablely equipped with Lower shaft sleeve 7, on described, following semiaxis 5,6 and bearing support 3 between adopt O type circle 8 to be sealed and matched, the described semiaxis 5 of going up, the corresponding end of Lower shaft sleeve 7 is installed with hemisphere spool 2 respectively, described hemisphere spool 2 is positioned at the valve body inflow port, go out on the runner between the head piece, and adopt seal ring with valve body 1 runner one side, sealed pressing sleeve is sealed and matched.
