Aviation hydraulic valve

The invention discloses an aviation hydraulic valve which comprises a valve body, an upper connecting block, a lower connecting block, a screw and a valve plate. The bottom face of the valve body communicates with a liquid inlet pipe, the outer side face of the valve body communicates with a liquid discharging pipe, and a flow control assembly is installed on the liquid discharging pipe. The flowcontrol assembly comprises a ball body, rotating rods are fixed to the top face and the bottom end of the ball body, and self-lubricating rotating assemblies are arranged at the joints of the rotatingrods and the inner wall of the liquid discharging pipe. According to the aviation hydraulic valve, an auxiliary assembly has the elastic effect, the stability of the hydraulic valve in the working state can be guaranteed, and the problem that liquid leaks due to unstable closing caused by large liquid pressure is solved; and the arrangement of the flow control assembly can be used for adjusting the flow of discharged liqu
