Description
Technical field
The utility model relates to a kind of valve, and in particular, it relates to a kind of ball valve had from pressure release sealing configuration.
Background technique
At present, valve is used for break-make gas pipeline or fluid pipeline, but deliver into pipeline owing to passing into after gas in pipeline or liquid mostly are pressurization, make in use valve process, owing to being trapped in the rising of the endoceliac gas of valve or liquid medium Yin Wendu, in the valve body that produces, cavity pressure is abnormal raises, valve body may be caused because of the excessive damage of pressure, make to cause other or leak of liquid.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can releasing pressure automatically, guarantee the ball valve had from pressure release sealing configuration of valve body safety.
For achieving the above object, the utility model provides following technological scheme: a kind of ball valve had from pressure release sealing configuration, comprise valve body, be arranged on the spheroid in valve body, and be arranged on valve rod spheroid stretching out valve body, described valve body is provided with the seal ring of contact spheroid, via openings one end of described seal ring contact spheroid, the one side of described seal ring spheroid is dorsad provided with bracing ring, described bracing ring and valve body slides are tightly connected, described bracing ring is provided with groove away from a side end face of seal ring, elastic component is provided with in described groove, one end that described elastic component stretches out groove is fixed on valve body.
The utility model is set to further: one end that described seal ring contacts with spheroid is that concave circular arcs is arranged.
The utility model is set to further: described valve rod and valve body contact place are provided with chuck, and described valve body corresponds to chuck place and is provided with the annular groove coordinated with chuck.
The utility model is set to further: the side of described chuck is provided with draw-in groove, is provided with spring in described draw-in groove, and one end that described spring is positioned at the opening of draw-in groove is fixed with steel ball, and the diapire of described annular groove is provided with the restraining groove coordinating steel ball.
The utility model has following advantage: by arrange on valve body with the use of bracing ring, elastic component and seal ring, when making that between valve body and spheroid, cavity pressure is excessive, medium in lumen can rely on the pressure of itself to promote seal ring and move towards bracing ring direction, seal ring is separated with spheroid, make the medium in lumen can obtain pressure release process, avoid and occur that valve body internal pressure is excessive, valve body is caused to damage, the situation of whole valve leak, by arranging seal ring and spheroid contact jaw is concave circular arcs, the area of contact of seal ring and spheroid can be improved, improve the sealing of valve body, avoid causing valve body to occur leakage situation in off position, by arranging annular groove chuck and valve body being arranged and matches on valve rod, valve rod and valve body can be avoided to come off, whole valve is caused to damage, by arranging spring in draw-in groove and draw-in groove and steel ball, and the restraining groove coordinated with steel ball is set, when valve rod can be made to rotate on valve body, can be conflicted by restraining groove and steel ball, make in the situation not using valve rod, valve rod there will not be the situation of rotation on valve body, make the stability that improve equipment.
