[0002] Gas filters are usually installed at the inlet end of pressure reducing valves, pressure relief valves, positioning valves or other equipment. A filter element is arranged inside, which can be used to remove impurities in the medium to protect the normal use of valves and equipment. After the filter element is used for a certain period of time, due to impurity blockage, it needs to be replaced. The existing gas filters have the following deficiencies when in use:

[0003] 1. The surface of the filter element cannot be cleaned, impurities are likely to block the filter element, increasing the replacement frequency of the filter element. Assembly and disassembly are likely to cause damage to the filter, thereby reducing the service life of the filter.

[0004] 2. The assembly and disassembly of the filter are relatively inconvenient, which is not conducive to replacing the filter element.

[0005] Therefore, we propose a gas filter capable of improving the service life. Content of the Utility Model
