Description

Technical Field

[0001] This utility model relates to the field of penetrant testing technology, specifically a PT penetrant testing reagent spraying device. Background Technology

[0002] Penetrant testing is one of the testing procedures that needs to be completed after aluminum alloy welding. Penetrant testing is a non-destructive testing method with many advantages such as not damaging the aluminum alloy, high accuracy, and high efficiency.

[0003] A search revealed that the Chinese patent with publication number CN218423489U discloses a penetrant testing reagent spraying device. Its key technical point is that it solves the problem of placing the penetrant testing reagent in a pressure bottle, requiring manual shaking of the bottle during use to prevent sedimentation and uneven application, which severely affects the spraying quality. Furthermore, current methods of spraying penetrant testing reagents involve manually applying the pressure bottle to the aluminum alloy, which is not only time-consuming and labor-intensive but also significantly reduces spraying efficiency, making it unsuitable for batch testing.

[0004] However, it was found that the above solution, with the nozzle pointing directly downwards, cannot guarantee that the surface of the test piece can be completely coated when spraying the reagent directly from top to bottom for some irregularly shaped test pieces. Furthermore, the spraying method, which does not allow for adjustment of the nozzle angle, affects the uniformity of the coating. In addition, the above solution does not have a structure to collect excess reagent, which falls directly to the ground, resulting in reagent waste.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
