Description

Technical Field

[0001] The present application relates to the technical field of valve nozzle detection, and in particular to a valve nozzle defect detection device. Background Art

[0002] During the automated production of valves, for the sake of production quality, the valves are tested for leaks. To improve efficiency, multiple valves are placed in a certain order on a testing jig for testing. During testing, how to transport the testing jig into the testing device and then transport the testing jig out after the test is completed is a technical problem that needs to be solved by those skilled in the art. However, existing valves are usually unable to detect the external dimensions, and the testing method is relatively single.

[0003] The structure of the product can refer to the valve nozzle multi-performance detection integrated assembly equipment disclosed in the Chinese patent document publication number: CN215677519U, which includes several conveying lines equipped with conveying carriers for loading aluminum nozzles, a first ventilation detection mechanism arranged on the side of the conveying carrier for detecting the ventilation condition of the through cavity, a second ventilation detection mechanism for detecting the ventilation condition of the side through hole, a valve core carrier for valve core loading and located below the conveying carrier to cooperate, a knob assembly arranged in sequence on the valve core carrier for inserting the knob valve core from the bottom of the through cavity, a first sensor assembly extending from bottom to top into the through cavity for detecting the concentricity of the valve core installed, a second sensor assembly extending from bottom to top into the through cavity for detecting the height of the valve core installed, and a sealing ring loading mechanism for rotating the sealing ring into the outer wall of the aluminum nozzle.

[0004] In the above structure, since only a single ventilation test can be performed, the test method is single and the effect is poor.

[0005] Therefore, a valve defect detection device with multi-process detection is needed. Utility Model Content
