Abstract

The invention relates to the field of valve machining, in particular to vertical ball core double-valve-seat grinding equipment. The equipment comprises flexible valve seat clamping mechanisms used for clamping a valve seat, a ball core rotating mechanism used for driving a ball core to rotate and a vertical lathe bed, the flexible valve seat clamping mechanisms and the ball core rotating mechanism are located on the vertical lathe bed and are of a vertical crossed structure, the number of the flexible valve seat clamping mechanisms is two, and the flexible valve seat clamping mechanisms are located on the upper side and the lower side of the ball core rotating mechanism respectively. According to the vertical ball core double-valve-seat grinding equipment, the problem that when a large-size or heavy valve seat in horizontal grinding equipment is clamped on the valve seat clamping mechanisms, due to the action of gravity, the installed valve seat naturally inclines, so that the pre-pressure is insufficient in the grinding process, and the grinding effect is affected is solved.

Description

technical field [0001] The invention relates to the field of valve processing, in particular to vertical spherical core double valve seat grinding equipment. Background technique [0002] The ball core and valve seat are the most critical parts that play a sealing role in the ball valve, so the machining accuracy, shape tolerance and roughness of the ball core and valve seat determine the quality of the sealing performance. Therefore, after the processing of general hard-sealed ball valves, the ball core and the valve seat need to be paired and ground to ensure the sealing surface of the ball core and the valve seat. In the existing grinding process, grinding is mainly performed by grinding equipment. [0003] For grinding equipment, it is mainly divided into two types: single-seat ball core matching grinding equipment and horizontal ball core double-valve seat grinding equipment. Among them, for single-seat ball core matching and grinding equipment, the valve seat is pres...
