Abstract

The invention relates to the technical field of pressure containers and energy storage, in particular to a constant-pressure type gas storage which comprises an air pipeline and a boss, a constant-pressure body capable of moving up and down is arranged above the boss, a groove is formed in the bottom of the constant-pressure body, and the constant-pressure body is meshed with the boss downwards through the groove. A gap is formed between the inner wall of the groove and the outer wall of the boss, a flexible film is arranged on the gap in a sealed mode, sealing liquid is loaded on the flexible film, and the air pipeline communicates with the groove from the outside. According to the constant-pressure type gas storage, the problems of pressure fluctuation and low volume efficiency of a gas storage in the prior art can be solved, the problem that the gas storage is prone to gas leakage in the high-pressure state can be effectively solved, and it is ensured that the gas storage can store gas at the constant pressure in the high-pressure state.

Description

technical field [0001] The invention relates to the technical field of pressure vessels and energy storage, in particular to a constant-pressure gas storage. Background technique [0002] The storage of compressed gas is of great significance to both industrial production and daily life, such as natural gas for thermal power plants, medical oxygen, compressed air energy storage, etc. In most cases, users of compressed gas have certain requirements for the quality of the gas supply, especially for the stability of the gas supply pressure. Therefore, the outlet pressure of the gas supply device must at least be guaranteed not to be lower than the pressure required by the user. When the gas in the gas supply device is discharged to a pressure lower than the pressure required by the user, the external gas supply has to be stopped, and the remaining low-pressure gas remains in the supply. On the other hand, in some cases, such as compressed air energy storage systems, due to the...
