Description

Technical Field

[0001] The utility model relates to the technical field of gas compressors, in particular to a compression chamber built-in valve structure of a gas compressor. Background Art

[0002] A gas compressor is a mechanical device used to compress a gas into a smaller volume and higher pressure. It works by increasing the distance between gas molecules and reducing the space they have free to move around. This results in an increase in the gas's pressure. Compressors are commonly used in industrial processes such as refrigeration, air compression, and chemical production. There are different types of gas compressors, including reciprocating, rotary screw, and centrifugal compressors. The choice of gas compressor depends on the specific requirements of the application. When selecting a gas compressor, it is important to consider the type of gas to be compressed, the desired output pressure and flow rate, and any specific environmental or safety requirements.

[0003] Although traditional gas compressors are very common and widely used, they still have some shortcomings. For example, their intake valves are mostly external, which not only takes up a large equipment space, but also is easily damaged by bumps and collisions due to its large amount of exposure, thus affecting its normal use. In addition, the structure of the intake valve is relatively fixed, so it is difficult to disassemble and assemble it during maintenance, which causes inconvenience in use. Therefore, in view of the above problems, a gas compressor compression chamber built-in valve structure is proposed. Utility Model Content

The built-in air intake valve not only saves a large amount of equipment space, but also is not easily damaged by bumps and collisions due to its small exposed portion, thereby ensuring its normal use. In addition, the structure of the air intake valve is relatively flexible, so it is convenient to disassemble and assemble it during maintenance, thereby not causing any inconvenience during use, thereby solving the problems raised in the above-mentioned background technology.
