Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application claims the benefit of Chinese Patent Application Nos. 202410431849.8 and 202420739270.3 filed on Apr. 10, 2024.

BACKGROUND In the existing filling technology, in order to ensure the safety of the steel cylinder in the process of filling and using, please refer to a steel cylinder for filling gases of Grant Publication No. CN207716079U, disclosed on Aug. 10, 2018. Generally, a safety needle valve (or safety valve) is additionally mounted on the existing cylinder, so that the gas inside the cylinder is discharged through the safety needle valve to balance the air pressure inside and outside the cylinder in case the pressure inside the cylinder is excessively high, so as to avoid the risk of blowing up of the existing cylinder. However, it is inevitable that existing cylinders are filled with air during refilling. In addition, it is inevitable that unused gas remains in the existing cylinders, so that it is likely to lead to the problem of impurity of the fuel due to the mixing of other gases if the air and the residual gas in the existing cylinders are not eliminated when new fuel is added to an interior of the existing cylinders. The safety needle valve of the existing cylinder is only used to ensure the safety of the existing cylinder. When the gas inside the existing cylinder is discharged to the outside under excessive pressure, the discharged gas contains a large amount of freshly filled fuel, which not only causes serious pollution to the environment, but also poses a safety hazard.
