Abstract
The utility model discloses a valve body of an eccentric half-ball valve. The valve body of the eccentric half-ball valve comprises a valve seat body, wherein a valve body is clamped on the valve seat body, a semicircular sealing plate is clamped between the valve body and the valve seat body, and the sealing plate is provided with an arc-shaped clamping groove which is matched with a spherical surface of the valve core. The valve body provided by the utility model has a combined design and is convenient and fast to assemble and disassemble, and meanwhile the sealing plate is added, thus the sealing effect of the valve body is improved, and an operator can easily operate independently.
Description
Technical field
The utility model relates to the eccentric half-ball valve field, specifically belongs to the valve body of 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 provides a kind of valve body 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:
The valve body of eccentric half-ball valve includes the valve seat body, and engaging has valve body on the described valve seat body, and clamping has semiorbicular shrouding between valve body and the valve seat body, and shrouding has the arc-shaped slot that matches with the sphere of spool.
Be provided with sealing gasket between described valve seat body 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
