Put the mode of valve body in vivo, eliminate because of the leakage hidden danger of valve body junction, valve can be kept to be used safely, extend valve and use the longevity
Life, assembly operation is simple simultaneously, saves the time, and cost lowers.
This utility model be employed technical scheme comprise that：A kind of ball valve, including valve body, be provided with described valve body by
Valve rod drives the spheroid of rotation, and described spheroid both sides are provided with the valve seat with ball seal cooperation, and described spheroid includes valve body I He
It is placed in the valve body II in valve body I, valve body I about is provided with flange, described valve body I and valve body II are respectively provided with valve seat, and valve body I
And valve body II diameter of bore is identical with the internal diameter of spheroid, outside described valve body I, it is provided with reinforcement, described valve body I upper end is provided with limit
Position end, equipped with filler above described positive stop end, positive stop end lowermost limit arranges the boss on valve rod, prevents valve rod from flying out, and eliminates
Potential safety hazard, described valve body I lower section reinforcement is connected with projection.
Described valve body I is set to step with valve body II junction and is connected, and is provided with sealing ring at step.
Described valve body I is same plane away from spheroid side and valve body II away from spheroid side.This side flange of valve body I connects
During pipeline, valve body II upper valve base 4 and the middle sealing of spheroid 3 are ensured by the extruding between pipeline and flange.
Described reinforcement and valve body I are integral type structure setting.
The beneficial effects of the utility model are：Due to taking technique scheme, effectively improve the valve of existing ball valve
The unstable problem of body junction sealing, this ball valve reasonable in design is simple, and good seal performance is built-in by valve body
The mode of valve body, eliminates because of the leakage hidden danger of valve body junction, valve can be kept to be used safely, extend valve service life, with
When assembly operation simple, save the time, cost lower.
