[description of drawings]
Fig. 1 is the longitudinal profile schematic diagram of the utility model gas emergency cut-off valve.
[embodiment]
Below in conjunction with accompanying drawing, by embodiment of the present utility model is described in further detail, make the technical solution of the utility model and beneficial effect thereof clearer, clear and definite.
Shown in accompanying drawing 1, the present embodiment, it comprises valve body 1 and is positioned at the valve gap 2 that valve body 1 top is spirally connected, valve gap 2 tops are provided with base 3, base 3 and the shell 4 formation cavity volume that is spirally connected, the coil 6 that the built-in and outside electric control element 5 of cavity volume is electrically connected to, astragal 6 is wound in the outer surface of guard grating 7, central rotating shaft 8 lower ends are positioned at the outlet chamber of valve body 1, the upper end extension exposes to shell 4 and handle ball 9 bolts, is disposed with movable part 10, electromagnetism battery core 11, little spring 12, pearl cutting ferrule 13, spring 14 and Sealing 15 on central rotating shaft 8.
In the present embodiment, described handle ball 9 is outside equipped with dust cover 16.
In the present embodiment, the built-in pearl 17 of described pearl cutting ferrule 13.
In the present embodiment, described electromagnetism battery core 11 is positioned at guard grating 7 epimere inner chambers.
In the present embodiment, described valve gap 2 is positioned at valve body 1 central position.
In the present embodiment, described shell 4 is provided with line hole 41, and the connecting line of coil 6 is worn cable-through hole 41 and connected described electric control elements 5.
In the present embodiment, described electric control element 5 is provided with arbitrary device of flameproof apparatus, gas-detecting device and viberation detector or their combination.
