AI Technical Summary
Existing technologies are insufficient for effectively detecting internal and surface defects in nuclear power plant lip-welded valves, especially in complex environments, where there are issues of missed or false detections. Furthermore, manual inspection poses risks of radiation and is inefficient.
An automatic eddy current inspection device for nuclear power plant lip weld valves was designed, including a fixing component, a drive assembly, a bracket, an eddy current sensor, and an elastic component. The device achieves radial and axial detection of the valve by rotating the eddy current sensor, and is suitable for valves of different diameters, avoiding manual inspection.
It enables efficient and stable testing of lip-welded valves in nuclear power plants, avoids the risk of artificial radiation, and improves testing effectiveness and efficiency.
