Brief description of the drawings
Fig. 1 is a kind of sectional view of gas emergency cut-off magnetic valve described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of gas emergency cut-off magnetic valve of the utility model, including valve body 1, bonnet 2, shut-off mechanism and
Electromagnetic Control mechanism, bonnet 2 are fixedly connected with valve body 1, and the valve port 7 of valve body 1 is set straight up, and bonnet 2 is located at the upper of valve body 1
Side, shut-off mechanism are fixedly installed on the top of bonnet 2 and are fixedly connected with bonnet 2, and Electromagnetic Control mechanism is fixed with shut-off mechanism
Connection；Shut-off mechanism includes cut-out shell 3, pulling shaft 5, fixed disk 6 and spring 11, and cut-out shell 3 is fixed on the upper of bonnet 2 vertically
Side, pulling shaft 5 are vertically arranged in cut-out shell 3, and can be slided up and down along cut-out shell 3, and fixed disk 6 is arranged in valve body 1,
And it is fixedly connected positioned at the top of valve port 7, the upper side of fixed disk 6 by circular cylinder elastic cotter 10 with the lower end of pulling shaft 5, spring 11
It is fixedly installed between the upper side of fixed disk 6 and the downside of bonnet 2, the sidepiece of pulling shaft 5 is provided with cut-out bayonet socket and path
Bayonet socket, path bayonet socket is positioned at the lower section of cut-out bayonet socket；Electromagnetic Control mechanism includes sealing shell 4, inductance coil 13 and movable iron
Core 12, the inner of sealing shell 4 are fixedly connected with cut-out shell 3, and movable core 12 is horizontally disposed, and the inner of movable core 12
It is resisted against in cut-out bayonet socket/path bayonet socket, inductance coil 13 is fixedly installed on the outside of movable core 12, and is located at sealing shell
In 4, sealing gasket 8 is provided with the downside of fixed disk 6, the distance between fixed disk 6 and valve port 7 block with path bayonet socket and cut-out
