The support to match with the arc surface of spheroid is provided between the gap of spheroid, support is provided with wear-resisting close to the side of spherome surface
Rubber strip；The end face of the abrasive rubber bar is in contact with the surface of spheroid；Equal movable sleeve is provided with the valve rod and fixing axle
Axle sleeve；The both ends of the support are fixedly connected with axle sleeve respectively；The bonnet upper end opens up fluted, and sealing dress is provided with groove
Put；The sealing device includes the cylinder being fixed on bonnet, is provided with sealing ring in cylinder, and sealing ring contacts with valve stem seal
Coordinate；The sealing ring outer surface is up-small and down-big taper surface；Throw-out collar, the periphery and cylinder of throw-out collar are provided with the cylinder
Inner headed face be engaged, the inner surface of throw-out collar is the conical surface being engaged with the taper surface of sealing ring；The cylinder internal upper part is set
There is screw thread, cylinder top is provided with the lid coordinated with its screw thread；Spring is provided between the external lid of the valve rod and throw-out collar.
Further, the spring one end is connected with lid, and the other end is connected with throw-out collar.
Further, described fixing axle one end is fixedly connected with valve seat, and the other end is rotated with spheroid and set.
Further, the axle sleeve is rotatably connected with valve rod and fixing axle respectively.
Had the following advantages that using the utility model：
First, throw-out collar is promoted by spring, due to throw-out collar and sealing ring cone match, turned so that upper sealing ring compresses
Axle, automatic compensation sealing can be achieved, avoid the medium in valve seat from being revealed along upper valve rod direction.In addition, lid is matched somebody with somebody with cylinder screw thread
Close connection, when the bounce effect of spring is bad, lid can be rotated, move down lid, shorten lid and throw-out collar it
Between distance, so as to further compression spring, increase the bounce of spring.
2nd, rotated in valve rod and drive when needing to close ball valve of spheroid, the through hole of spheroid is slowly transferred to valve body
Sealing surface, now fluid is with the rotation of spheroid, and in the gap for gradually flowing into spheroid and valve body, fluid has certain flow velocity,
Because axle sleeve and valve rod or fixing axle activity coordinate, support will be made to drive abrasive rubber bar to be rotated on the surface of spheroid,
So as to strike off the attachment impurity of spherome surface, the service life of valve is improved.
Brief description of the drawings
Fig. 1 is a kind of structural representation of ball valve provided by the utility model；
Fig. 2 is the cooperation schematic diagram of abrasive rubber bar and spheroid.
Embodiment
