[0026] When using an explosion-proof flame arrester of the utility model, the upper shell 101 and the lower shell 102 are both hemispherical, so as to increase the impact resistance. The upper shell 101 and the lower shell 102 are first connected to the pipeline, and then the fire-blocking net 104 is slidably installed inside the mounting shell 106. The limiting ring 105 limits the position of the mounting of the fire-blocking net 104, and then the first flange 108 and the second flange 109 on the mounting shell 106 are connected and installed, so as to fix the mounting shell 106 between the upper shell 101 and the lower shell 102.
