Abstract
The utility model discloses a buffer type eccentric semispherical valve which comprises a valve body, wherein a valve seat body is fixedly arranged at one end of the valve body; an inlet end is arranged at the outer side of the valve seat body; the other end of the valve body is an outlet end; a semispherical valve core is arranged in the valve body; an upper half shaft and a lower half shaft are respectively arranged at the upper end and the lower end of the valve core; a sealing pressing sleeve is arranged in the inlet end; a sealing valve core is fixedly arranged at the outer side of the valve core; a sealing ring body is pressed between the sealing valve core and the sealing pressing sleeve; and a bellows is connected onto the outlet end. According to the buffer type eccentric semispherical valve disclosed by the utility model, due to the adoption of the valve body combined design, the buffer type eccentric semispherical valve is convenient and quick in mounting and dismounting; and meanwhile, the bellows is additionally arranged, so that the buffer effect of the valve body is improved and independent operation of an operator is easily realized.
Description
Technical field
The utility model relates to buffering type 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 buffering type eccentric half-ball valve are arranged, and the sealing that seals the buffering type eccentric half-ball valve firmly 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 buffering 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, 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 buffering type eccentric half-ball valve, and valve body modular design and easy installation and removal are quick, sets up bellows simultaneously, has improved the stablizing effect of the water outlet of valve body, and the easy operating personnel carry out separately.
The technological scheme of the utility model is following:
The buffering type 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, are provided with sealed pressing sleeve in the entrance point, and the spool outside is fixed with sealed valve core; Press between sealed valve core and the sealed pressing sleeve and be equipped with the sealing circle body, be connected with bellows on the described outlet end.
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 material of described bellows is a plastic material.
The valve body modular design and the easy installation and removal of the utility model are quick, set up bellows simultaneously, and bellows has the shape of wave, and be effective to the water flow impact pressure of buffering outlet end, improved the sealing effect of valve body, and the easy operating personnel carry out separately.
Description of drawings
Fig. 1 is the structural representation of the utility model.
