[0002] A pressure vessel is a closed container that can withstand pressure. Pressure vessels are widely used. They play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most used are in the chemical industry and petrochemical industry, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used for heat transfer, mass transfer, reaction and other process processes, as well as storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industrial and civil fields, such as air compressors. Various types of special compressors and auxiliary machines of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are all pressure vessels, but pressure vessels are generally large pressure vessels. When welding, the pressure vessel barrel is heavy, the starting resistance is large, the rotation is difficult, and it is inconvenient to operate manually. Therefore, those skilled in the art provide a pressure vessel welding positioning device to solve the problems raised in the above background technology. Utility Model Content
