Description

technical field [0001] The invention relates to the technical field of pipeline filters, in particular to a pipeline filter for recoil cleaning. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to eliminate impurities in the medium to protect the normal operation of the valve and equipment. In use, when the fluid enters the filter cartridge with a filter screen of a certain specification, the impurities in the filter are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, take out the detachable filter cartridge and reinstall it. Yes, but the filter needs to be cleaned regularly, so as not to filter out too much impurities or plug the filter screen, and repeatedly disassemble and assemble to waste manpower and financial resources.
