The invention discloses a jet pipe servo valve capable of adjusting axis position of a nozzle. The jet pipe servo valve comprises a valve body, a jet nozzle which is arranged on the upper part of the valve body is controlled through a torque motor, adjustment end covers which are arranged on two ends of the valve body, a pressure detection device, a valve bush arranged in the valve body, a valve core arranged in the valve bush and a receiving base which is embedded in the valve core and is used for receiving a flow beam of nozzle jet flow, wherein two jet flow receiving holes are formed in the jet flow receiving base; the two jet flow receiving holes separately communicate with cavities at two ends of the valve core in the valve bush through receiving slot holes formed in the wall of the valve bush; the pressure detection device comprises two pressure detection holes formed in the jet flow receiving base and first pressure sensors arranged on the end covers; and the two pressure detection holes are separately connected with the pressure sensors through detection slot holes formed in the wall of the valve bush. Compared with the prior art, the jet pipe servo valve has the advantages that the axis position of the nozzle can be adjusted; the nozzle is arranged with the axis being centered front and back, so that a leakage rate in the jet pipe servo valve is lowered; and the like.
