Abstract
The utility model discloses an eccentric half-ball valve, comprising a valve body, wherein a valve seat body is fixedly installed at one end of the valve body; an inlet end is disposed outside the valve seat body; an outlet end is disposed at the other end of the valve body; a hemispherical valve core is disposed in the valve body; an upper half shaft and a lower half shaft are installed at the upper end and the lower end of the valve core respectively; a sealing press sleeve is disposed in the inlet end; a sealing valve core is fixedly disposed outside the valve core; and a sealing ring body is pressed between the sealing valve core and the sealing press sleeve. The valve body of the eccentric half-ball valve disclosed by the utility model is designed in a combined manner as well as is convenient and fast in installation and detachment; and a sealing plate is added, so that the sealing for the valve body is enhanced in effect and easy to independently perform by operating personnel.
Description
Technical field
The utility model relates to the eccentric half-ball valve field.
Background technique
It is a lot of in pipeline, to work the ball valve kind of blocking medium, and hard seal eccentric ball valve and soft seal eccentric half-ball valve are arranged, and the sealing of hard seal eccentric semi ball valve is a metal to metal; The mutual friction of phase-contact surface meeting phase makes to be sealed with certain leakage after long-time the use, and 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, its complex structure, installation and maintenance convenience in use; 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 the utility model provides a kind of eccentric half-ball valve, and valve body modular design and easy installation and removal are quick, sets up a shrouding simultaneously, has improved the sealing effect of valve body, and the easy operating personnel carry out separately.
The technological scheme of the utility model is following:
Eccentric half-ball valve includes valve body, and valve body one end is installed with the valve seat body; The valve seat body outside is provided with entrance point, and the other end of valve body is provided with outlet end, is provided with hemispheric spool in the valve body; The upper end of spool, lower end are separately installed with semiaxis, following semiaxis; Be provided with sealed pressing sleeve in the entrance point, the spool outside is fixed with sealed valve core, presses between sealed valve core and the sealed pressing sleeve to be equipped with the sealing circle body.
Said going up between semiaxis and the valve body is provided with Upper shaft sleeve, is provided with Lower shaft sleeve between described semiaxis down and the spool.
Be provided with the shrouding of annular between described spool and the valve body.
The valve body modular design and the easy installation and removal of the utility model are quick, set up a shrouding simultaneously, have improved the sealing effect of valve body, and the easy operating personnel carry out separately.
