Abstract

The invention relates to the technical field of battery management systems, and discloses a cleaning method for a long-service-life high-reliability universal valve for a spacecraft. Cleaning is conducted through a cleaning box, the cleaning box comprises a water tank and an upper cover, the interior of the water tank is of a stepped structure and used for containing products of different lengths, and a water inlet hole is formed in the upper end of the side face of the water tank; the lower end of the other side face is provided with a water outlet hole which is in a flowing state in the cleaning process. The cleaning box is made of plastic, the proportion of the cleaning solution is suitable for cleaning different propelling product materials, and the cleaning problem of different materials is solved. The device is simple in structure and convenient in clamping process, saves solution consumption through an internal stepped structure, is suitable for cleaning products with different lengths, and improves production efficiency. After the cleaning process is adopted, the cleaned inner hole part does not contain redundant materials, and the internal and external quality is improved.

Description

technical field [0001] The invention relates to the technical field of spacecraft propulsion, in particular to a long-life and high-reliability general valve cleaning method for spacecraft. Background technique [0002] Spacecraft products such as electric explosion valves, add and exhaust valves, filters, pressure reducers, self-locking valves, check valves, gas test interfaces, etc. have high requirements on the internal and external quality of the products. Before connecting, they need to be cleaned to remove excess In order to prevent the existence of excess objects from scratching the sealing surface and other structures, resulting in product failure Art is completed. [0003] If the welding method is used, it is also necessary to ensure that the cleaning position is free of oxides, the pickling amount of the outer diameter size should be consistent, and the coaxiality should be good, so as to ensure that the appearance quality of the weld after welding is smooth, and ...
