A profiled
abrasive grain flow clamp for inner hole finishing
processing of a tee valve is characterized by comprising a large upper cover, a support ring, a bottom large cover plate, a bottom small cover plate, a large end core mold, a small end core mold, a bottom core mold, an L-shaped column and a side plate. By placing the core mold in the valve flow channel, an
abrasive flow channel following the inner wall surface of the valve body is formed, so that the
abrasive flowing through the inner wall surface of the valve body has a faster flow rate and a larger pressure, thereby improving the
material removal rate. By installing the core mold with a profiled structure, the uniformity of the abrasive
processing of the inner wall surface of the valve body can be improved, thereby obtaining better inner wall surface quality. The abrasive is repeatedly circulated in the valve body, thereby removing
casting defects, increasing the
surface finish and also obtaining a relatively low valve body inner wall
surface roughness. The present application effectively improves the
processing efficiency and precision of the abrasive grain flow on the valve body inner cavity, and provides a new method for valve finishing.
