Abstract
The utility model discloses an eccentric semispherical valve, which comprises a spherical valve body. Two ends of the valve body are respectively an inlet end and an outlet end. A spherical valve core is rotatably installed in the valve body, the upper end and the lower end of the valve core are fixedly connected with a rotating shaft, an abrasion resistant layer is arranged on the valve core at the position corresponding to the inlet end, a ladder-shaped groove is arranged in the abrasion resistant layer, an abrasion resistant sleeve is sleeved in the inlet end of the valve body, and a protruding ring matched with the groove is arranged at the rear end of the abrasion resistant sleeve. The eccentric semispherical valve resolves the problem that the valve is complex in structure and inconvenient to install and maintain, free opening of the valve is affected caused by scaling and working efficiency is low, so that sealing performance further improves.
Description
Technical field
The utility model relates to the ball valve field, specifically belongs to eccentric half-ball valve.
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 is in order to remedy the deficiency of prior art; A kind of eccentric half-ball valve is provided, has solved complex structure, installation and maintenance convenience, had influence on the unlatching freely of valve because of the generation of scale formation; Inefficiency, sealability further improves.
The utility model is realized through following technological scheme:
Eccentric half-ball valve includes spherical valve body, and the valve body two ends are respectively entrance point, outlet end; Be rotatablely equipped with spherical spool in the said valve body; The upper and lower end of spool is fixedly connected with rotating shaft respectively, and spool and entrance point corresponding position are provided with wearing layer, have trapezoidal groove in the wearing layer; Be set with wear-resistant sleeve in the entrance point of valve body, the rear end of wear-resistant sleeve has the protruding circle that matches with groove.
Described wearing layer is the hemizonid shape.
The utility model has adopted the protruding circle and the wear-resistant sleeve that cooperatively interact to be sealed and matched, and has solved complex structure, installation and maintenance convenience, because of the generation of scale formation has influence on the unlatching freely of valve, and inefficiency, sealability further improves.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, eccentric half-ball valve includes spherical valve body 1; Valve body 1 two ends are respectively entrance point 2, outlet end 3, are rotatablely equipped with spherical spool 4 in the valve body 1, and the upper and lower end of spool 4 is fixedly connected with rotating shaft 5 respectively; Spool 4 is provided with wearing layer 6 with the entrance point corresponding position, and wearing layer 6 is the hemizonid shape, has trapezoidal groove 7 in the wearing layer; Be set with wear-resistant sleeve 8 in the entrance point of valve body 1, the rear end of wear-resistant sleeve 8 has the protruding circle 9 that matches with groove.
Claims (2)
1. eccentric half-ball valve includes spherical valve body, and the valve body two ends are respectively entrance point, outlet end; It is characterized in that: be rotatablely equipped with spherical spool in the said valve body; The upper and lower end of spool is fixedly connected with rotating shaft respectively, and spool and entrance point corresponding position are provided with wearing layer, have trapezoidal groove in the wearing layer; Be set with wear-resistant sleeve in the entrance point of valve body, the rear end of wear-resistant sleeve has the protruding circle that matches with groove.
2. eccentric half-ball valve according to claim 1 is characterized in that: described wearing layer is the hemizonid shape.
