Wherein, the bottom of lower valve rod is designed to sphere, and the tip designs of valve base is the conical surface, forms the sealing of sphere and the conical surface.
Rotate by the handle positive and negative direction, drive the upper valve rod rotation, upper valve rod drives the lifting of lower valve rod straight line by coupling, valve opening or close.
The utlity model has following advantage:
1, the valve base plug-in type is installed in the import stomidium of valve body, by two road O RunddichtringOs on the valve base cylindrical and the sealing of valve body inner round wall, sphere is combined with the entrance point conical surface of valve body and is formed the conical surface and ball face sealing bottom valve base again, and double seal guarantees valve base and valve seal effect.
2, the bottom of lower valve rod is designed to sphere, and the tip designs of valve base is the conical surface, forms the sealing of sphere and the conical surface, has improved sealing effect.
3, the lower valve rod bottom is designed to sphere, has alleviated the scouring force of medium to sealing surface, improved using effect and the life cycle of product.
4, the material of movable valve base can require to select according to process engineering, improve abrasion resistance, wear resistance and the corrosion resistant performance of product, strengthen sealing effect and the life cycle of valve, reduce production costs, maintenance of valve is very convenient, particularly only need during large bore valves maintenance valve base seal face valve base is extracted out just can keep in repair, service failure as long-term in the valve base warp, only need to change valve base or keep in repair to get final product, whole deck valve door still can continue to use, greatly reduce user cost, improve the recycling rate of product.
