The utility model discloses a high-pressure gas pressure reducing device. It comprises a valve body, an air inlet and an air outlet, pressure gauge interface, the diaphragm assembly and its adjusting device, thimble device, which is characterized in that the thimble device located in the body below is a connecting thimble device, the spring is arranged on the extended socket sleeve, the sleeve is arranged on the lower end of a heat radiator used. Because the thimble device is connected with the outer part of the thimble and is provided with a heat conducting piece, the working condition is improved, and the influence of frosting and cooling is overcome. When the inlet temperature is 0 centigrade, high and low voltage single-stage regulator can be directly from 20 ~ 0.8MPa to 0.3 ~ 25MPa between the normal work of decompression conversion, gas chamber temperature of - 40 ~ - 60 C. The utility model is suitable for use in the gas decompression equipment of various pipelines, cylinders and confluence groups.
