It is necessary to provide an environmentally friendly, portable and easy-to-operate cleaning method to solve the problem that the inner cavity oil channel of the hydraulic valve body is affected by unclean cleaning, etc.

[0003] There are some shortcomings in the traditional sand cleaning methods commonly used to clean the oil passages in the inner cavity of hydraulic valve body castings: (1) Electrochemical sand cleaning is highly polluting and not environmentally friendly, and its use is restricted by the state; (2) Shot peening sand cleaning is limited by the structure of the oil passages in the castings and cannot completely clean the sand in the oil passages, which may cause quality risks to product performance or even quality problems; (3) Air flow vibration sand cleaning may cause the weak connection parts of the castings to crack or break and become scrapped. The above methods all require a relatively large device or system, which is relatively fixed in position, cannot be used portable, and has a relatively high cost. The utility model can effectively solve the above shortcomings and problems. Utility Model Content
