The pipeline flame arrester consists of a connecting flange and a fire-blocking core structure inside it. The fire-blocking core has multiple layers of narrow channels. When the flame passes through the channel, a large amount of heat exchange occurs. After the heat exchange, the temperature drops below the ignition point, thereby achieving the purpose of fire blocking.

[0010] As a preferred technical solution of the utility model, blocks are fixedly arranged in the first cover shell and the second cover shell, and a fire-blocking core is arranged in the first cover shell and the second cover shell and between the two blocks.

[0011] As a preferred technical solution of the utility model, the ends of the first cover shell and the second cover shell that are away from each other are both connected with flanges, and a plurality of screw holes are arranged at equal distances on the surface of the flanges.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] The movement and adjustment of the moving block is achieved through the cooperation of the threaded rod and the adjusting button.
