Problems solved by technology

[0004] The gas filters in the prior art are all aimed at pipeline gas and impurities in the gas, rather than bottled gas; because the cleanliness of bottled gas is relatively high, it is generally liquefied when bottled, and during use, Non-vaporized liquid will also enter the filter, which will cause the filter to be clogged and the gas output will be greatly reduced, and once there are impurities, it will easily cause the filter to be blocked, which will affect the normal use of the cooktop. The gas filter in the prior art has poor stability in use

Abstract

A gas filter comprises a shell (1). An outlet (3) is formed in the upper end of the shell (1). An inlet (4) is formed in the lower end of the shell (1). The communication position of the inlet (4) and the communication position of the outlet (3) in a filter cavity are provided with a first annular protrusion (5) and a second annular protrusion (6) respectively. The inlet (4) is communicated with the filter cavity (2) through the first annular protrusion (5). The outlet (3) is communicated with the filter cavity (2) through the second annular protrusion (6). A partition piece (7) is arranged between the first annular protrusion (5) and the second annular protrusion (6). At least two first protrusions (8) are arranged at the lower end of the partition piece (7). At least two second protrusions (9) are arranged at the upper end of the partition piece (7). The free end of the first annular protrusion (5) and the free end of the second annular protrusion (6) are each provided with a radial through groove (10). Compared with the prior art, the gas filter has the advantages of aiming at bottled gas and being not prone to blockage and high in use stability.

Description

technical field [0001] The invention relates to a filter, in particular to a gas filter for bottled gas. Background technique [0002] At present, gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, cities, households and other gas fields. Gas filter is an indispensable device on the medium pipeline, usually installed at the inlet end of pressure reducing valve, pressure relief valve, positioning valve or other equipment to eliminate impurities in the medium to protect the normal operation of valves and equipment Use, reduce equipment maintenance costs. [0003] When the fluid enters the filter with the filter element, its impurities are blocked by the filter element, and the clean filter air is discharged from the filter outlet. When cleaning is required, just disassemble the filter cartridge, take out the filter element, and reinstall it after cleaning. Therefore, the gas filter is extremely conven...
