Technical Field

[0001] The utility model belongs to the technical field of globe valve processing, and particularly relates to a globe valve leak detection tooling. Background Technique

[0002] A globe valve, also known as a stop valve, belongs to a forced-sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. After the globe valve is produced, it is necessary to detect the leak of the globe valve.

[0003] The traditional globe valve leak detection method is to use a submersion test, that is, submerge the globe valve in water and then inject high-pressure gas. By observing whether bubbles are generated in the water, the sealing performance of the globe valve is judged. For example, the leak detection method mentioned in the utility model patent with the publication (announcement) number CN216309344U. Such a method is easy to operate and has high efficiency, but has the following deficiencies:

[0004] 1. When the leaked bubbles are small or the leakage is slow, it is not convenient for manual observation:

[0005] 2. The submersion test generally can only know whether the globe valve leaks air, but cannot know the specific leakage position, which is not convenient for returning to the factory for repair. Content of the Utility Model
