Structure Design and Analysis of Reservoir Fill Selector Valve in Civil Aircraft

The hydraulic system of modern airliners may leak out of the system. So it is necessary to regularly refill and maintain the hydraulic system on the ground. The operation is complicated and inefficient. In this paper, the structure design and analysis of the reservoir fill selector valve in the integration filling system are carried out. Study the structure characteristics, advantages and disadvantages of foreign valves. The comparative analysis is made from the aspects of weight, size, cost, life and leakage. The structure is optimized based on the E-type valve. The leakage of the new valve structure is calculated and verified to meet the system requirements, which can be used as the structural model of the domestic aircraft integration filling system reservoir fill selector valve.
