When the flame arrester assembly inside the flame arrester body 100 needs to be maintained, it is only necessary to remove the nuts on the threaded rods from the side to remove the cover plate 200. When the cover plate 200 is removed, the partition plate B201 is separated from the cover plate 200 synchronously, and at this time, the flame arrester rack 300 is freed from the limit, so that the flame arrester rack 300 is removed to perform maintenance operations on the internal structure.

[0044] Furthermore, both ends of the flame arrester body 100 are provided with welded and fixed flanges 101 , and the flanges 101 are provided with a plurality of through holes, so that the flame arrester body 100 can be connected to other pipelines through the flanges 101 .

[0045] Working principle:

[0046] When in use, the fire-blocking disc body 400 is inserted into the interior of the fire-blocking disc frame 300, and the pressing piece A500 is embedded in the interior of the fire-blocking disc frame 300. The two card slots on the fire-blocking disc frame 300 and the pressing piece A500 are buckled and wrapped around the two ends of the fire-blocking disc body 400, so as to limit the fire-blocking disc body 400. The fire-blocking disc body 400 is blocked by the pressure strip 501, which can effectively prevent the internal structure of the fire-blocking disc body 400 from falling apart. The outer side of the pressing piece B502 is in contact with the inner wall of the fire-blocking disc frame 300. The spring sheet 503 is made of elastic steel, and the pressing piece B502 is in an arc shape. The spring sheet 503 and the pressing piece B502 are in an arc shape. The sheet B502 is welded and fixed, and a gasket 504 is provided inside the fire-blocking disc frame 300. The pressing sheet B502 is pressed on the spring sheet 503 to compress the spring sheet 503. After the spring sheet 503 is squeezed, the arc shape expands, thereby pushing the pressing sheet B502 and the pressing sheet A500 to press on the fire-blocking disc body 400 to limit the fire-blocking disc body 400, which can effectively prevent the fire-blocking disc body 400 from shaking. The sealing cover 505 and the pressing plate 506 are an integrated structure, and the pressing plate 506 is pressed on the gasket 504, so that the pressure strip 501 continuously squeezes the spring sheet 503 to limit the fire-blocking disc body 400.

[0047] Furthermore, after the internal structure of the fire-blocking disc rack 300 is assembled, it is inserted into the interior of the flame arrester body 100, and the two partitions A103 are respectively wrapped on one side of the clamping ring A301 and the clamping ring C507, and the two partitions B201 are respectively wrapped on the other side of the clamping ring A301 and the clamping ring C507, so as to clamp and limit the fire-blocking disc rack 300, thereby completing the installation. When disassembling, it is only necessary to remove the nut on the threaded rod from the side to remove the cover plate 200. When the cover plate 200 is removed, the partition B201 and the cover plate 200 are separated synchronously. At this time, the fire-blocking disc rack 300 is freed from the limit, so that the fire-blocking disc rack 300 is removed to perform maintenance operations on the internal structure.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
