The invention relates to an anti-icing water pressure type gas storage cabinet. The gas storage cabinet comprises a water storage chamber and a gas storage chamber on the lower part and an upper waterpressure chamber isolated through a vault, wherein the water storage chamber and the gas storage chamber are integrated. The water pressure chamber is connected with the water storage chamber throughan oblique communicating pipe. The water storage chamber is internally provided with a gas inlet pipe and a gas outlet pipe which extend outwards from the bottom. The top end of the gas inlet pipe and the top end of the gas outlet pipe communicate with the gas storage chamber. A pressure limiting pipe penetrates through the vault and the water pressure chamber to extend out of the cabinet top, and the bottom end of the pressure limiting pipe extends into water in the water storage chamber. The cabinet top is provided with a manhole. The inner wall of a cabinet body is sequentially provided with a heat preservation interlayer, a heating plate and a waterproof protection layer. According to the anti-icing water pressure type gas storage cabinet, it does not need to consume power, energy sources are saved, the running cost is low, pressure is stable, icing does not occur in the low-temperature weather, and the use ratio is increased.
