Description
Technical Field
The utility model belongs to the technical field of the filter technique and specifically relates to a gas filter convenient to dismantle and decontaminate.
Background
Gas filters are important devices in gas distribution systems. In the process of gas distribution, in order to ensure the normal operation and protect the gas distribution equipment and instruments such as pressure regulators, valves, flow meters, pressure meters and the like from being damaged, solid impurities in the gas must be removed, and a filter with satisfactory filtering precision must be installed in front of the solid impurities, so that the filter with periodic pollution discharge is developed and produced for the requirements.
The gas filter is widely applied to: metering of city pipeline (network) gas, metering of industrial gas, metering of gas pressure regulating station, energy management and other metering matching devices of various non-corrosive gases.
If the blowdown structure of the gas filter is not good, the service life of the filter can be greatly reduced, the use effect is achieved, if solid impurities in a filter cavity cannot be effectively cleaned, long-term siltation can cause the filtering function of the filter, and chain reaction can be caused to cause other problems of a pipeline system.
In the past, the gas filter is entirely disassembled to clean solid impurities in a pipeline, so that the disassembly is troublesome, for example, the gas filter with large caliber such as 80, 100 and 150 can be disassembled by cooperation of a plurality of persons, and secondly, the assembly environment is complex in many times, and if the whole gas filter is disassembled to discharge the sewage, the subsequent assembly is inconvenient.
Disclosure of Invention
The utility model provides a gas filter which is convenient to disassemble and clean, and overcomes the defects of the prior art, and is additionally provided with a filter element pressing plate, a spring and a structure of an inner hexagonal cylinder head screw plug; therefore, the filter not only plays a role in filtering and fixing impurities, but also is convenient for the filter to be detached and cleaned.
In order to realize above-mentioned purpose, design a gas filter convenient to dismantle and decontaminate, including filter pipeline, chimney filter, its characterized in that: one side of the filter pipeline is connected with a filter tube, a filter element assembly is arranged in the filter tube, one end of the filter element assembly is abutted against the bottom in the filter tube, and the other end of the filter element assembly is connected with a filter element pressing plate; the end part of the filter tube is connected with the filter cover through a hexagon bolt, a spring washer and a flat washer, an inner hexagon cylinder plug screw and an O-shaped ring are arranged in the center of the filter cover, and the inner hexagon cylinder plug screw is connected with the filter element pressing plate through a spring.
The filter element pressing plate is of a disc-shaped structure, and a cylindrical protruding structure is arranged in the center of the filter element pressing plate.
One end of the spring is sleeved on the cylindrical protruding structure at the center of the filter element pressing plate, and the other end of the spring is abutted to the bottom of the inner hexagonal cylinder plug screw.
And a lead sealing line and a lead seal are arranged on the filter cover.
And another O-shaped ring is arranged between the filter tube and the filter cover.
Compared with the prior art, the utility model provides a gas filter convenient for disassembly and decontamination, which is added with a filter element pressing plate, a spring and a structure of an inner hexagonal cylinder head screw plug; therefore, the filter not only plays a role in filtering and fixing impurities, but also is convenient for the filter to be detached and cleaned.
