At the same time, the gas can easily flow from the air hole 12. At this time, the baffle 8 is overturned by the airflow. When flame combustion occurs and explosion suppression is carried out, the temperature in the pipeline body 1 rises sharply. At this time, the thermosensitive glass ball 18 is broken by heat, and the spring 6 rebounds and resets to make the slide 7 pull the baffle frame 9 to move outward, and the baffle frame 9 is engaged with the fixed plate 5, so that the fixed plate 5 and the baffle frame 9 are supported by the thermosensitive glass ball 18 and the airflow channel is closed.

[0023] In the utility model, the cooling assembly includes a plurality of water channels 14, and the plurality of water channels 14 are respectively opened inside the fixed plate 5 and the baffle frame 9.

By starting the electric ball valve 4, external cooling water enters the fixed plate 5 from the water inlet pipe 3, and then circulates the cooling water in the fixed plate 5 and the baffle frame 9 through the water channel 14 and flows out from the water outlet pipe 10, so that the fixed plate 5 and the baffle frame 9 are cooled.

At the same time, the electric ball valve 4 is started to allow external cooling water to enter the fixed plate 5 from the water inlet pipe 3, and then the cooling water circulates in the fixed plate 5 and the baffle frame 9 through the water channel 14, and flows out from the water outlet pipe 10, so that the fixed plate 5 and the baffle frame 9 are cooled.
