Description

Technical Field

[0001] The utility model relates to the technical field of adjusting valve body hole processing, and particularly relates to a coated fixture for a drilling machine for processing adjusting valve body holes. Background Technique

[0002] The adjusting valve body mainly consists of a valve body, a valve seat, a valve core, an actuator and accessories. The adjusting valve body is a crucial component in an industrial automation control system. It is mainly used to control parameters such as the flow rate, pressure, and temperature of fluids to meet the requirements of the process. The adjusting valve body receives signals from the control system and automatically adjusts the opening of the valve, thereby achieving precise control of the medium flow rate;

[0003] After the drilling process of the adjusting valve body is completed, in order to ensure that its surface is properly protected, a coating is usually applied. However, the fixture design widely used in current coating operations tends to directly clamp on the outer surface of the adjusting valve body. This inevitably causes the problem of coating loss in the clamping area, which in turn has an adverse impact on the uniformity and aesthetics of the overall coating of the adjusting valve body, greatly reducing the coating effect and failing to fully exert its due protection function.

[0004] Therefore, a coated fixture for a drilling machine for processing adjusting valve body holes is proposed. Content of the Utility Model
