Abstract
The utility model discloses a valve core of a reinforced wear-resistant eccentric half ball valve. The valve core comprises a spherical body, a valve rod penetrating the spherical body, and a valve plate body arranged on the front end of the spherical body, wherein a notch is formed on both ends of the valve plate body respectively; a wear-resistant layer is arranged on the inner wall of the notch; an antirust layer is arranged on two side walls of the valve plate body; and a reinforcing rod is connected with the valve rod and the inner side wall of the valve plate body. The valve core provided by the utility model solves problems existing in the prior art, such as complicated structure, inconvenience in mounting and maintenance, adverse influence on the smooth opening of the valve caused by scaling, and low work efficiency, and is resistant to rust and corrosion and is not easy to be damaged after long-term use.
Description
Technical field
The utility model relates to the ball valve field, specifically belongs to the spool of reinforced wear-resisting eccentric half-ball valve.
Background technique
It is a lot of in pipeline, to work the ball valve kind of blocking medium, and the spool of hard seal eccentric ball valve and the reinforced wear-resisting eccentric half-ball valve of soft seal is arranged, and the sealing that seals the spool of reinforced wear-resisting 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 the spool of the reinforced wear-resisting eccentric half-ball valve of soft seal 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 is in order to remedy the deficiency of prior art, a kind of spool of reinforced wear-resisting eccentric half-ball valve to be provided, and has solved the problem of complex structure, installation and maintenance convenience, has antirust corrosion resistant effect, long-term use not fragile.
The utility model is realized through following technological scheme:
The spool of reinforced wear-resisting eccentric half-ball valve; Include spheroid, pass valve rod on the spheroid, the front end of spheroid is the valve plate body; The two ends of valve plate body have breach; The inwall of breach is provided with wearing layer, is resin layer on the two side of valve plate body, is connected with reinforcing bar on valve rod and the valve plate body madial wall.
The front-end face of described spheroid has groove.
Be fixed with stabilier on the outlet end inwall of the utility model valve body, solved complex structure, installation and maintenance convenience, have antirust corrosion resistant effect, long-term use is not fragile.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, the spool of reinforced wear-resisting eccentric half-ball valve includes spheroid 1; Pass valve rod 7 on the spheroid 1, the front end of spheroid is a valve plate body 2, and the two ends of valve plate body 2 have breach 3; The inwall of breach 3 is provided with wearing layer 4; Be resin layer 5 on the two side of valve plate body, be connected with reinforcing bar 8 on valve rod 7 and valve plate body 2 madial walls, the front-end face of spheroid has groove 6.
