[0002] Acetylene is an organic compound with the chemical formula C2H2, commonly known as wind coal or calcium carbide gas. It is the smallest member of the alkyne compounds. It is a colorless gas at room temperature and pressure. It is slightly soluble in water, soluble in ethanol, acetone, chloroform, benzene, and miscible in ether. It is one of the important raw materials for organic synthesis and a monomer for synthetic rubber, synthetic fibers and plastics. It can also be used for oxyacetylene welding and cutting.

[0003] In the prior art, in the production process of acetylene gas, acetylene gas needs to be stored through a storage device. Conventional acetylene gas storage devices are mostly single gas storage tanks. During use, the lower surface of the storage tank is often bumped and easily damaged. Compared with last year, the lower surface of the storage tank lacks mobility. In some work, the acetylene gas storage tank needs to be moved frequently, and manual transportation can only be adopted, which is time-consuming and labor-intensive. The control valve on the acetylene gas storage tank lacks protection function, and during the loading process, there is a lack of lifting structure, which is not convenient for lifting. At the same time, the control valve has the problem of air leakage. Utility Model Content
