Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of alarm type flame arrester for pipe, including back-fire relief Supervisor 7, one end of the back-fire relief supervisor 7 are fixedly connected with the one end of transitional pipe segment 5 by reducing connecting leg 6, the transitional pipe segment 5 Middle part is connected with observation window 12, and the other end of the transitional pipe segment 5 is fixedly connected with connecting tube 3, the company by second flange 4 Adapter 3 is fixedly connected with air inlet pipe 1 and escape pipe 16 by first flange 2, and the back-fire relief supervisor's 7 is internally provided with the first resistance The fiery fire-retardant core 14 of core 9 and second, the crevice place of the fire-retardant core 14 of the first fire-retardant core 9 and second are provided with cavity 13, and described The outside of one fire-retardant core 9 and the second fire-retardant core 14 is fixedly connected with explosion-proof ring 8, and the middle part of second fire-retardant core 14, which is run through, fire Flame detector 11, the top of the back-fire relief supervisor 7 are provided with alarm 10, and the top of the flame detector 11 is internally provided with Control mainboard 17, the bottom of the flame detector 11 are fixedly connected with detection silk 19, and the middle part of the flame detector 11 is set It is equipped with metal connecting leg 18.
