The servo mechanism adopts an energy selection valve to realize hydraulic energy redundancy, and the energy selection valve adopts two-position three-way valves. Two oil sources enter the energy selection valve at the same time. Under the normal working state, two oil sources respectively supply oil to the two servo mechanisms. When one path of oil source breaks down, the oil pressure is reduced, and the pressure difference between two ends of the energy selection valve is greater than the designed switching pressure difference, the energy selection valve starts to switch, and the oil source with normal pressure replaces the fault oil source to supply oil to the servo mechanism.
