[0002] The valve body is widely used in many fields and is an indispensable component in fluid control systems. In these fields, the valve body plays a variety of roles, such as controlling flow, regulating pressure, cutting off channels, preventing reverse flow, and reducing noise and vibration. It is of irreplaceable importance to ensure the normal operation of equipment and the smooth progress of production. When processing the valve core ball on the valve body, it is often necessary to use a clamping tool to fix it for easy processing.
