Description

Technical Field

[0001] The utility model relates to the technical field of double filters, in particular to a double filter which is easy to assemble and disassemble. Background Art

[0002] The duplex filter is mainly used to filter impurities in the lubricating oil. The duplex filter includes two filters and a switching valve. The two filters are connected in parallel. The switching valve is installed between the two filters. The lubricating oil enters from the inlet of the switching valve, flows to the two filters for filtration, and then flows to the switching valve and flows out from the outlet of the switching valve, thereby completing the filtration of the lubricating oil.

[0003] During the use of the duplex filter, the filter element in the filter needs to be cleaned regularly to prevent clogging. Especially when the equipment is in a relatively harsh working condition, the deterioration of the lubricating oil will be accelerated (the impurities in the lubricating oil will increase). At this time, it is necessary to shorten the cleaning cycle of the filter element and increase the cleaning frequency.

[0004] At present, during the operation of the duplex filter, the sealing cover needs to be removed before the filter element is disassembled and cleaned, which reduces the disassembly efficiency. Therefore, it is necessary to propose a duplex filter that is easy to disassemble to solve the above problems. Utility Model Content
