Description

Technical Field

[0001] This utility model relates to the field of air valve manufacturing technology, and in particular to a positioning tooling for air valve manufacturing and processing. Background Technology

[0002] Gas valves are key components for controlling gas flow. They mainly consist of a valve body, valve seat, valve disc (valve core), valve stem, spring, and seals. They achieve unidirectional flow control by opening and closing channels or adjusting flow / pressure, and are widely used in industrial pipelines, dust removal systems, and silo unloading.

[0003] When the air valve needs to be drilled or processed, a positioning fixture is required to position and fix the air valve body. However, most of the existing positioning fixtures can only perform simple fixing work on the air valve. Since air valves usually have inclined surfaces, when it is necessary to process the inclined surfaces, the positioning fixture cannot adjust the fixing inclination according to the processing requirements, which greatly reduces the flexibility of the positioning fixture.

The inner wall of the threaded sleeve is threadedly connected to the surface of the bidirectional threaded rod, and the threaded sleeve is fixedly connected to the bottom surface of the limiting slider.
