Description

Technical Field

[0001] This application relates to the field of valve processing equipment, and in particular to a valve seat processing equipment. Background Technology

[0002] Currently, valves are control components in fluid transport systems. When machining valve seats, in addition to machining the valve stem hole, flange holes also need to be machined on the valve flange surface. Current techniques for machining valve seats require first drilling the valve stem hole using a valve stem hole machining machine. After machining, the valve seat is removed from the valve stem hole machining machine and then installed on a flange hole machining machine to drill the flange hole. Finally, it is mounted on a grinding machine to grind the flange surface. This entire process is time-consuming, labor-intensive, and inefficient. Furthermore, positioning errors may occur when installing the valve seat on different machines, affecting the quality of the finished product. Utility Model Content
