Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant tanks, in particular to a fire retardant tank for a low-inlet and high-exhaust hydrogen-oxygen machine. Background Art

[0002] The fire arrester tank for oxyhydrogen machine is also called oxyhydrogen flame arrester. Its main function is to prevent combustion accidents of oxyhydrogen machine. By controlling the combustion process of the oxyhydrogen machine, the combustion speed can be slowed down, thereby effectively preventing the ejection of flames. When a combustion accident occurs in the oxyhydrogen machine, the flame arrester will automatically cut off the hydrogen and oxygen supply to avoid further expansion of the fire, thereby ensuring the safety of the machine.

[0003] The existing low-inlet and high-exhaust fire arrester tanks for hydrogen-oxygen machines are generally installed in pipelines for conveying flammable gases during use to prevent the spread of flammable gas flames. However, impurities and residues will accumulate in the fire arrester tanks during use. When the staff cleans the fire arrester tanks, since the fire arrester tanks are assembled by matching nuts and screws, and the screws and nuts are arranged in a circular shape on the mounting ring, the nuts at both ends of the screws need to be removed in turn when the fire arrester tanks are disassembled, which causes inconvenience to the staff in disassembling the fire arrester tanks and cleaning impurities. Therefore, a new type of low-inlet and high-exhaust fire arrester tank for hydrogen-oxygen machines is urgently needed to solve these problems. Utility Model Content
