Description

Technical Field

[0001] The utility model relates to the technical field of precision filtering, in particular to a precision filter. Background Art

[0002] The filter is a vital device in the fluid delivery system. Its main function is to remove impurities from the medium and ensure the normal operation of valves and related equipment in a pure medium environment. When the fluid passes through the filter cartridge equipped with a filter screen of a specific specification, the impurities will be effectively intercepted, while the pure filtrate or gas will pass through the filter smoothly and be discharged from the outlet. In order to maintain the performance of the filter, once cleaning is required, the user only needs to simply remove the detachable filter cartridge, perform necessary treatment, and then install it again.

[0003] However, in the existing technology, some filters have problems of insufficient filtering accuracy and relatively small filtering area, which to a certain extent limits their filtering efficiency and cannot meet the growing demand for high-quality fluid filtration. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the present case. Utility Model Content
