英文摘要	The invention belongs to the field of electrohydraulic control engineering and particularly relates to an underwater hydraulic servo valve pressure compensation structure. A filter compensator which keeps inside and outside pressures of a servo valve shell consistent is mounted on a servo valve and provided with a pressure compensation hole. A screen which filters fluid flowing into the servo valve shell is fitted in the pressure compensation hole. The filter compensator comprises a screen cover plate, a screen and a screen base. One end of the screen base is fitted into a mounting hole arranged in a seal end cap of the servo valve, and the other end of the screen base is connected with the screen cover plate. The screen is compressed onto an inner step of the screen base through the screen cover plate. The screen cover plate and the screen base are both provided with pressure compensation holes. Through the use of the underwater hydraulic servo valve pressure compensation structure, the problem that the current electrohydraulic servo valve is unable to operate in the deep-sea high pressure environment is solved; the underwater hydraulic servo valve pressure compensation structure has the advantages of compact structure, reliable performance, low failure rate, low cost, ease of implementation and the like.
