Technical Field

[0001] The utility model relates to the technical field of oil and gas barrel pressure relief, in particular to an oil and gas barrel internal pressure relief device. Background Art

[0002] The air compressor oil-gas barrel (also called oil-gas separation barrel or oil-gas tank) is an important component in the compressed air system. Its main function is to separate the oil mist in the oil-gas mixture generated by the air compressor during operation.

During the actual use of this type of oil and gas barrel, the working pressure of the air compressor oil and gas barrel is usually high. During the operation of the compressor, pressure fluctuations may occur in the oil and gas barrel. When the pressure in the oil and gas barrel is too high, it may cause damage to the structure of the oil and gas barrel, and even cause the oil and gas barrel to leak or burst. Therefore, it is necessary to release the high pressure in the oil and gas barrel; therefore, an oil and gas barrel internal pressure relief device is proposed to solve the above problem.
