Multi-stage pressure reducing valve

The invention discloses a multi-stage pressure reducing valve, and relates to the technical field of valves. The valve comprises a valve body, a water inlet pipe and a water outlet pipe are arranged at the bottom and one side of the valve body correspondingly, a through valve rod is inserted into the top of the valve body, a middle frame is fixedly connected to the bottom of the valve rod, a plurality of plugs with conical bottoms are fixed to the periphery of the middle frame, and cavities are formed in the plugs; the periphery of the cavity is provided with two sets of first-stage water outlets and second-stage water outlets which are through, the first-stage water outlets are located below the second-stage water outlets, and the number of the first-stage water outlets is larger than that of the second-stage water outlets. According to the multi-stage pressure reducing valve, multi-stage pressure reduction can be conducted in the valve body, then the valve body is closed, the closing difficulty is lowered,
