Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1~2 are please referred to, the utility model provides a kind of technical solution: a kind of fire prevention emergency shutoff device, including valve body
1, the valve body 1 is interior to be equipped with valve chamber 7, and the side of the valve body 1 is equipped with the import 8 being connected with valve chamber 7, the bottom of the valve body 1
Portion is equipped with the outlet 9 being connected with valve chamber 7, and the top of the valve body 1 is fixedly connected with meltable pin limit lid 6, described meltable
The inside top of pin limit lid 6 is fixedly connected with one end of the first spring 5, the other end and the body of rod 16 of first spring 5
Top be fixedly connected, the top of the valve body 1 is equipped with the guide ring 13 for being socketed in 16 outside of the body of rod, and the body of rod 16 is through leading
It is inserted in valve chamber 7 to ring 13, the effect of guide ring 13 is exactly that guiding role is provided to the body of rod 16, and the bottom of the body of rod 16 is solid
