Description

TECHNICAL FIELD

[0002] The pressure vessel is a closed equipment for containing gas or liquid and bearing pressure.

[0003] The pressure vessel is a closed container capable of bearing pressure. The pressure vessel has a very wide range of uses and plays an important role and function in many departments such as industry, civil use, military industry and many fields of scientific research. Among them, the pressure vessel is used most in the chemical industry and the petrochemical industry, and the pressure vessels used in the petrochemical industry account for about 50% of the total number of pressure vessels.

[0004] The pressure vessel is mainly used for heat transfer, mass transfer, reaction and other process in the field of chemical industry and petrochemical industry, and is used for storing and transporting gas or liquefied gas under pressure. The pressure vessel is also widely used in other industrial and civil fields, such as air compressor. Various special compressors and auxiliary machines (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) of refrigeration compressors belong to pressure vessels.

[0005] The sealing cover is particularly important to be fixed because the pressure vessel bears a certain pressure. The existing equipment is partially fixed by screwing a plurality of bolts at the corners of the sealing cover. However, it is troublesome to disassemble and screw a plurality of bolts each time. With the progress of pressure vessel materials, a thread is gradually formed on the outside of the pressure vessel, and a thread is also formed on the inner wall of the sealing cover. The two are connected by screwing, and a sealing gasket or other sealing structure is added at the connection to ensure sealing, so as to achieve the purpose of convenient disassembly.

[0006] However, due to the threaded connection, the thread is inevitably worn during long-term use. Therefore, it is necessary to add an anti-loosening structure. The existing anti-loosening structure is mostly a secondary reinforcement structure such as a bolt or a buckle, which makes disassembly more complicated.

[0007] Therefore, an anti-loosening structure capable of convenient disassembly and good fixing effect is needed. UTILITY MODEL CONTENT
