Abstract
The utility model discloses an eccentric hemispherical valve comprising a spherical valve body and a hemispherical valve spool, wherein both sides of the valve body are respectively provided with a flow inlet and a flow outlet, a valve rod is fixed in the valve body, the upper end of the valve rod penetrates through the valve body, and the lower end of the valve rod is installed in the valve body in a rotating way. The utility model has simple structure and high working efficiency and is convenient to install and use. Meanwhile, the service life and the economic benefit are enhanced, so that the application range of this class of valves is more extensive.
Description
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 includes spherical valve body, hemisphere spool, and the both sides of described valve body are respectively equipped with inflow port, go out head piece, described valve body internal fixation has valve rod, valve body is passed in the upper end of valve rod, and the lower end of valve rod is rotated and is installed in the valve body, is connected with connecting rod between valve body and the valve rod.
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.
