Problems solved by technology

[0002] Originally, our PRV pressure regulating valve has been assembled during the production process. After the pressure setting process is completed, the product valve leakage test will be carried out to test whether our pressure regulating valve products leak. During the normal production process, there will be a certain proportion. Leakage, for these leaked products, rework will be carried out. The method is to flush with CH20 oil. This rework method has the defect that effective rework cannot be carried out. The main reasons are:
[0003] 1. During the process of flushing the sealing surface with CH20 oil, the valve core is not fully opened, only one side is opened, and a small half of the surface is not opened, so the sealing surface is not 100% flushed, and there are still foreign objects Sticking to the sealing surface, which continues to cause leakage
[0004] 2. For the foreign matter on the sealing surface, only flushing with CH20 oil cannot effectively remove it, and foreign matter still adheres to the sealing surface
