Abstract
In the modern industrial society, gas cylinders are widely used as a mobile pressure vessel, they also have close relationship with people in the social production and social life. Cylinder technology has become the research hot spots around the world. There still exist many problems in the design of the gas cylinder domestically, such as less study on its mechanism, less standardization on design process and so on. It will have a great theoretical and practical value to do research in the field. In this paper, the existing structure of the gas cylinder is study, and the overall structure of a double-cylinder is designed by taking into account domestic and foreign literature. The solid model of the product is completed. It will be useful for the design standardization of the gas cylinder.
