[0002] Filters play an important role in the petrochemical industry, often used to remove solid particles, impurities, and other contaminants from liquids or gases to protect equipment, improve product quality, and extend equipment life. Filters are an indispensable device on pipelines conveying media, typically installed on pressure reducing valves, pressure relief valves, and constant water level valves to facilitate the inlet of other filter equipment. A filter consists of a cylinder, a stainless steel filter screen, a sewage discharge section, a transmission device, and an electrical control section. A filter that is easily disassembled and assembled typically features simplified disassembly and maintenance, facilitating quick cleaning, replacement of filter elements, and other maintenance operations. Easily disassembled filters make maintenance more efficient and convenient, improving the operational reliability and service life of the equipment.

[0003] The existing filter that is easy to disassemble and assemble is not convenient for disassembling and assembling the filter cover in actual use.
