Abstract
The utility model discloses a valve core for a pressure release type ball valve. The valve core comprises a hemispherical body. A plane-shaped valve plate is positioned on an outer end face of the hemispherical body, a pressure release channel is arranged in the middle of the valve plate, a conical hole is positioned in the pressure release channel, a sealing ball is matched in the conical hole, and a spring is pressed on the outer side of the sealing ball. The valve core uses a one-way valve to release overhigh pressure at a valve port, can bear impact of high-pressure water flow, prevents the ball valve from being damaged by overhigh pressure, and is convenient and quick to install and dismount and easy to operate for operator individually.
Description
Technical field
The utility model relates to the eccentric half-ball valve field, specifically belongs to the spool of pressure-relief type semispherical 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 spool of pressure-relief type semispherical valve; Adopt one-way valve unloader valve port excess pressure, can bear the water impact of high pressure, guaranteed that ball valve can not damage because of overpressure; And easy installation and removal is quick, and the easy operating personnel carry out separately.
The technological scheme of the utility model is following:
The spool of pressure-relief type semispherical valve includes hemisphere, and said hemisphere outside end face is provided with plane valve plate, and the middle part of valve plate has pressure release passage, and pressure release passage has conical bore, is combined with ball sealer in the conical bore, and the outer side pressure of ball sealer is equipped with spring.
The described valve plate outside is provided with boss.
The utility model adopts one-way valve unloader valve port excess pressure, can bear the water impact of high pressure, guaranteed that ball valve can not damage because of overpressure, and easy installation and removal is quick, and the easy operating personnel carry out separately.
