Description

Technical Field

[0001] This utility model is a quick-opening corrosion-resistant filter, belonging to the field of corrosion-resistant filter technology. Background Technology

[0002] Carbon steel filters are an indispensable device in pipelines transporting media. They are usually installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to remove impurities from the media and protect the valves and equipment. When fluid enters the filter cartridge containing a filter screen of a certain size, impurities are blocked, while clean filtrate is discharged from the filter outlet. When cleaning is required, simply remove the detachable filter cartridge, clean it, and reinstall it. Therefore, it is extremely convenient to use and maintain.

[0003] Chinese patent CN216395541U discloses a carbon steel corrosion-resistant filter with a quick-connect head. By using a positioning block and a positioning groove at the connection end, the carbon steel corrosion-resistant filter and the connecting pipe can be quickly aligned and positioned, reducing the difficulty of docking. Furthermore, the fixing sleeves and connecting accessories fixed at the connecting flanges at both ends of the carbon steel filter body enable quick and secure connection. The operation is simple, stable, and improves installation efficiency. However, during use, manual holding of the filter and connecting flange is still required before bolting; otherwise, it is prone to detachment, leading to lower installation efficiency. There is an urgent need for a quick-opening corrosion-resistant filter to solve these problems. Utility Model Content
