Description

Technical Field

[0001] The utility model relates to the technical field of oil filter elements, in particular to a quick-detachable gas compressor oil filter element. Background Art

[0002] The filter is an indispensable device on the pipeline that conveys the medium. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, water level valve, and other equipment of the filter. The filter consists of a cylinder, a stainless steel filter screen, a sewage discharge part, a transmission device, and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, just remove the detachable filter cartridge, treat it, and reinstall it. Therefore, it is extremely convenient to use and maintain. In the existing technology, the filter of the gas compressor often passes through the oil and needs to be removed regularly for cleaning.

[0003] However, in order to facilitate the replacement of the filter element during use, a quick-release method is designed to install the filter element in the filter cartridge. Now, the filter element is basically fixed in the filter cartridge by threads. However, since it is filtering the engine oil, the engine oil can easily enter the threaded connection between the filter element and the filter cartridge. In the long run, this affects the stability of the connection of the filter element. In order to solve the above problem, we designed a quick-release gas compressor oil filter element.
