The utility model relates to the technical field of high-pressure reducing valve adjustment, and discloses a high-pressure reducing valve adjusting device which comprises a valve body, a water inlet
pipe is fixedly connected to one side of the valve body, a water outlet
pipe is fixedly connected to the other side of the valve body, a connecting rod is rotationally connected to the interior of the valve body, and a gate plate is fixedly connected to the outer wall of the connecting rod. A fixing plate is fixedly connected to the interior of the valve body, and a buffer
assembly is arranged in the fixing plate; the buffering
assembly comprises a hollow frame and a sliding frame, the outer wall of the hollow frame is fixedly connected to the outer wall of the fixing plate, and the sliding frame is slidably connected to the interior of the hollow frame. According to the pressure reducing valve,
water flow flows into the valve body from the water inlet
pipe and then is discharged through the water outlet pipe, so that the effect of buffering and pressure reducing on the
water flow passing through the valve body is achieved, the problem that the
water flow directly impacts the gate plate in the valve body for a long time, and consequently the valve plate moves or inclines is solved, and the service life of the pressure reducing valve is prolonged.
