The pressure reducing valve with the air tightness monitoring function comprises a pressure reducing valve body, one side of the pressure reducing valve body is communicated and connected with a water conveying pipe, the water conveying pipe is provided with a differential pressure sensor, the inner wall of the water conveying pipe is rotationally connected with a rotating rod, and the rotating rod is in threaded connection with a filter screen. And the top of the rotating rod is fixedly connected with a fan-shaped side plate. Through cooperation of the differential pressure sensors and the pressure reducing valve body, the whole pressure reducing valve does not need to be disassembled, the pressure difference between the front end and the rear end of the pressure reducing valve body is monitored through the two differential pressure sensors, the problem that pipeline leakage possibly occurs when the pressure reducing valve is disassembled for detection is avoided, and the monitoring steps are reduced; the bo
