Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, and in particular to a water-gas common nozzle used in the energy storage field. Background Art

[0002] Energy storage mainly refers to the storage of energy, and its main function is to store electrical energy in various forms and release it when needed, so as to realize energy transfer in the time dimension. At present, most of the water-gas common nozzles used in the field of energy storage on the market are equipped with springs and cylindrical pistons inside the nozzles. When low-pressure perfluorohexanone gas needs to be sprayed, the low-pressure perfluorohexanone gas will not push the cylindrical piston in the nozzle, so that the perfluorohexanone gas can be sprayed out through the nozzle on the nozzle. When high-pressure water mist needs to be sprayed, the high-pressure water will push the cylindrical piston in the nozzle downward, so that the high-pressure water mist can be sprayed out through the nozzle on the nozzle. The nozzle can spray perfluorohexanone gas and high-pressure water mist from two different nozzles. For example, a dual-medium nozzle for energy storage power stations disclosed in Chinese Patent Announcement No. CN216439873U, but because the spring and the cylindrical piston are both inside the nozzle, and the spring and the cylindrical piston can only be replaced after the nozzle needs to be removed from the pipeline, which makes the spring and the cylindrical piston more troublesome to replace. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: at present, most of the water-gas common nozzles used in the field of energy storage on the market are provided with a spring and a tubular piston inside the nozzle. When low-pressure perfluorohexanone gas needs to be sprayed, the low-pressure perfluorohexanone gas will not push the tubular piston in the nozzle, so that the perfluorohexanone gas can be sprayed out through the nozzle on the nozzle. When high-pressure water mist needs to be sprayed, the high-pressure water will push the tubular piston in the nozzle downward, so that the high-pressure water mist can be sprayed out through the nozzle on the nozzle, so that the perfluorohexanone gas and the high-pressure water mist can be sprayed from two different nozzles. Since the spring and the tubular piston are both in the nozzle, and the spring and the tubular piston can only be replaced after the nozzle needs to be disassembled from the pipeline, which makes the spring and the tubular piston more troublesome to replace. A water-gas common nozzle for energy storage is proposed.
