Said valve rod is connected with the upper end of valve gap through lining near the part of handle, flexibly connects through screw thread between valve rod and the lining, and lining is fixedly connected with valve gap;
The lower end of said valve gap and valve body upper surface are tightly connected; The valve gap center is provided with stuffing hole, and the intermediate portion of valve rod passes stuffing hole, is filled with stuffing box packing between the hole wall of valve rod and stuffing hole; Be provided with gland above the said stuffing hole, gland is connected with valve gap through screw and fixes.
Optimal technical scheme as the utility model; Said valve rod is parallel to the axis of said valve body import, and the end of valve rod is provided with guide rod, and valve body import inner chamber is provided with guiding rib; The guiding rib center is provided with pilot hole, said guide rod stretch in the pilot hole and relatively pilot hole move up and down.
As the optimal technical scheme of the utility model, constitute flexible connection through screw thread between said guide rod and the pilot hole.
As the optimal technical scheme of the utility model, have a plurality of through holes on the said guiding rib.
As the optimal technical scheme of the utility model, the axis normal of said valve body import is in the axis of valve outlet.
As the optimal technical scheme of the utility model, the import of said valve body and outlet are respectively equipped with the flange fillet.
As the optimal technical scheme of the utility model, be made as flexible connection between said valve rod and the sealing cover.
As the optimal technical scheme of the utility model, said valve gap is connected with valve body through bolt, is provided with seal ring between valve gap and the valve body.
The beneficial effect of the utility model is: with respect to existing technology; The utility model is provided with guiding rib at valve body import inner chamber; The guiding rib center is provided with pilot hole; Guide rod plays guiding and the firmly effect of sealing cover through pilot hole, and sealing cover is connected with the sealing surface formation rigid seal of transitional pore.The utility model sealing is reliable, easy to operate, is particularly useful for the major diameter kingston valve.
