In said structure, pressed seat is set in the installation cavity of valve body to be compressed positioning action to the Sealing being tightly connected with spherical crown on valve seat and prevents that hemisphere spool from extruding valve seat by Sealing under impacting being subject to pressure medium, guarantee the connectivity robustness of Sealing, damping spring sheathed on valve rod can be to having good cushioning effect between semispherical valve core and valve interior wall, avoid hemisphere spool being subject to collision frequently under medium impact and between valve interior wall, especially valve body is near the inwall at place, valve road.
As further setting of the present utility model, described Sealing comprises and the domatic hemisphere Sealing connecting of spherical crown, the end of hemisphere Sealing is connected with frustum link, and the domatic tangent end face of described valve seat and spherical crown offers the groove that is embedded with frustum link adaptation.
In said structure, Sealing passes through its hemisphere Sealing and the domatic tangent butt of spherical crown, and is arranged on valve seat by its frustum link, and this frustum link is connected more firmly and is difficult for deviating from valve seat.
As further setting of the present utility model, on described spherical crown is domatic, be coated with rubber pad, rubber pad and described Sealing connect.
This spherical crown in said structure, on spherical crown is domatic, covers rubber pad, with Sealing butt, increases both sealing surface scopes, even if also can guarantee that along with hemisphere spool has certain displacement sealing surface is effective.
As further setting of the present utility model, described pressed seat is provided with Z-shaped step surface towards the end face of valve seat, described valve seat has towards the end face of pressed seat the bearing surface coordinating with Z-shaped step surface, and the end face relative set that is connected with Z-shaped step surface on described pressed seat becomes the ramp structure being connected smoothly towards the end face of spherical crown with valve seat.
In said structure, pressed seat coordinates with the bearing surface of valve seat by Z-shaped step surface and plays positioning action and avoid it to be subject to external impacts occurring that upper and lower displacement causes pressed seat to lose efficacy to the compression of Sealing.
As further setting of the present utility model, described rubber pad comprises the rubber pad body with the domatic laminating of spherical crown, and one end of rubber pad body is provided with and the most advanced and sophisticated adaptive flanging of spherical crown.
In said structure, the flanging of rubber pad body can strengthen the stability of rubber pad, avoids it to be subject to External Force Acting and is offset.
Adopt such scheme, the utlity model has structural stability, good seal performance, there is good shock-absorbing capacity.
Below in conjunction with accompanying drawing, the utility model is further described.
