[0044] The structure of this filter station is suitable for high-pressure liquid filtration. Under normal working conditions, the liquid flows into the filter cartridge 401 through the liquid inlet of the liquid inlet collecting block 1, the first ball valve 2, the liquid outlet of the liquid inlet collecting block 1, and the liquid inlet of the base 403. A filter element is installed in the filter cartridge 401 to filter the liquid. The filtered liquid flows out from the liquid outlet of the filter cartridge 401 and the liquid outlet of the base 403.
