Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1~5 are please referred to, the present invention provides a kind of technical solution: the fire prevention quick action emergency valve of meltable formula, including rotary opening valve
10 and control mechanism 19, the rotary opening valve 10 includes valve body 11, shaft 20, valve deck 13 and valve plate 12, the two sides of the valve body 11
It has been respectively communicated with outlet 1 and import 2, has been rotatably connected to shaft 20 in the valve body 11, the side of the shaft 20 is fixed with valve
Plate 12, the valve plate 12 are located at one end of outlet 1, and the control mechanism 19 includes shift fork cabinet 15, the shift fork cabinet 15
Side is connected with the second cylinder 8, and the other side of the shift fork cabinet 15 is connected with the first cylinder 7, the shaft 20 it is another
In side insertion shift fork cabinet 15 and it is fixedly connected with shift fork 16, the side of the shift fork 16 is equipped with card slot 5, second cylinder
The piston rod 17 for extending through shift fork cabinet 15 and the first cylinder 7 is equipped in 8, the left side of the piston rod 17 is fixed with limit and lives
