The invention relates to an oxygen pressure reducer for an underwater respirator. The oxygen pressure reducer comprises a pressure reducing valve body. A high-pressure air input assembly is connectedto the pressure reducing valve body. A pressure reducing assembly is arranged in the pressure reducing valve body. A pressure reducing base is arranged at one end of the pressure reducing assembly. The pressure reducing base is movably connected with the pressure reducing valve body. An adjusting assembly is arranged at the other end of the pressure reducing assembly. The adjusting assembly is movably connected with the pressure reducing valve body. A high-pressure chamber is arranged at the position, where the pressure reducing assembly is located, of the pressure reducing valve body. A low-pressure chamber defined by the adjusting assembly and the pressure reducing valve body is arranged on the outer side of the pressure reducing assembly. A valve port is formed between the high-pressurechamber and the low-pressure chamber. One or more low-pressure connectors are further formed in the pressure reducing valve body. A pressure safety valve is arranged on one low-pressure connector. The oxygen pressure reducer for the underwater respirator has the advantages of being convenient to adjust, good in sealing performance, reliable in breathing air source and the like.
