SUMMERY OF THE UTILITY MODEL
The utility model aims at solving among the prior art "the through-hole is seted up to the foundry goods itself more, very much to the great and thinner with through-hole junction pore wall thickness of foundry goods ball cavity volume for the foundry goods receives the defect that adds the easy crackle that produces in man-hour at the later stage, thereby provides an ultra-low temperature ball valve body foundry goods.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an ultra-low temperature ball valve body foundry goods, includes the valve body, the ball die cavity has been seted up on the valve body, ball die cavity upside is equipped with first through-hole, ball die cavity bottom side is equipped with second through-hole and third through-hole, first through-hole, second through-hole, third through-hole centre of a circle and ball die cavity central point are located the same axis, the ball die cavity is equipped with supporting mechanism, the valve rod through-hole has been seted up to valve body bilateral symmetry, valve body bilateral symmetry is provided with the ring flange, a plurality of screw holes have evenly been seted up on the ring flange, a plurality of bosses of fixedly connected with on the second through-hole inner wall, supporting mechanism includes the bracing piece, the bracing piece is the cross setting, fixedly connected with damping gasket on the bracing piece, damping gasket tightly.
Preferably, a plurality of the reinforcing blocks are distributed in an annular uniform array, and a transverse reinforcing rib is arranged between every two reinforcing blocks.
Preferably, the diameter of the second through hole is larger than that of the third through hole.
Preferably, the two sides of the flange are symmetrically provided with positioning bulges, and the positioning bulges and the valve body are integrally formed.
Preferably, each reinforcing block is provided with a buffer inclined plane.
Compared with the prior art, the beneficial effects of the utility model are that: when the valve body is further subjected to surface machining, the supporting rod and the damping gasket are matched to elastically support the spherical cavity, so that the impact strength of the valve body is improved, the deformation of the spherical cavity is prevented, and meanwhile, the supporting rod and the damping gasket can be directly taken out from the spherical cavity after the machining is finished in order not to influence the subsequent use of the valve body. Increase the intensity that second through-hole department corresponds the valve body through the cooperation of boss and horizontal strengthening rib, avoid adding man-hour production crackle, simultaneously because the boss distributes for the annular also can not lead to corresponding valve body department thickness too thick, the buffering inclined plane can lead to and cushioning effect to the fluid that the ball die cavity flows through the second through-hole to reduce the valve and open the direct impact effect of back fluid pressure difference to the valve body suddenly, guarantee the life of valve.
