Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a gas filter. Background Technique

[0002] Gas filters are widely used in gas-using fields such as metallurgy, chemical industry, petroleum, paper-making, medicine, food, mining, power, cities, and families. A gas filter is an indispensable device on the pipeline for conveying the medium. It is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a positioning valve or other equipment to remove impurities in the medium to protect the normal use of valves and equipment and reduce equipment maintenance costs.

[0003] For existing gas filters, it is difficult to remove or install them. Then, when performing daily maintenance or replacing the filter element, more time and energy will be consumed. Frequent disassembly and installation of the sealing cover, especially in cases where the operation is inconvenient, may damage its original sealing performance. The decline in sealing performance will increase the risk of gas leakage, which will in turn affect the operation efficiency and safety of the equipment. This not only increases the difficulty and complexity of maintenance work, but also may affect the normal operation time of the equipment, reducing the overall maintenance efficiency. At the same time, attention needs to be paid to the protection of pipeline connections. Content of the Utility Model
