Apical axis upper surface is provided with teeth groove, and tooth bar apical axis engages each other with reset switch.
Preferably, described reset switch stretches out the part of valve body and is provided with bar-shaped trough.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model simple in construction, reasonable in design, with low cost, can automatically cut off combustion gas and supply when earthquake occurs
Should, prevent gas pipeline from destroying and cause leakage and the generation of secondary disaster.
2, use electric magnet that iron ball is carried out son's wife, regulating magnet pair can be carried out by size of current is adjusted
The suction of iron ball, and then regulate the sensitivity of this product sensing earthquake, it is adaptable to multiple different occasions, advantageously general in promoting
And.
3, when earthquake occurs, iron ball is rolled into gas outlet pressure contact switch, and signal communicating circuit is connected, and now combustion gas is public
Control centre of department receives signal, reminds staff to cut off gas supply, further increases combustion gas peace during coming earthquake
The person of Quan Xing, effectively the protection people and property safety.
4, by arranging reset switch and tooth bar apical axis, when needing to connect combustion gas after earthquake, only need to rotate with instrument
Reset switch makes tooth bar apical axis push iron ball, makes iron ball again adsorb on electric magnet, can reclose combustion gas.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of intelligent fuel gas for earthquake disaster closes valve, and being specially one can be certainly when earthquake
The dynamic valving closing gas pipeline, including valve body 3, is provided with cavity in valve body 3, the top of valve body 3 cavity be provided with connect into
The air inlet 1 of feed channel, the bottom of valve body 3 cavity is provided with the gas outlet 2 connecting outlet pipe.Valve body 3 cavity inside gas outlet 2
Both sides be provided with inclined-plane 5, gas outlet 2 is positioned at low-lying place, and the cavity inner wall of side, gas outlet 2 is provided with electric magnet 6, electric magnet 6
Being adsorbed with iron ball 4, the diameter of iron ball 4 is more than the internal diameter of gas outlet 2.
When there is earthquake, ground and building shake, when the inertia force acted on iron ball 4 is more than electric magnet 6
During to the suction of iron ball 4, iron ball 4 i.e. departs from electric magnet 6, and rolls down along inclined-plane 5 under gravity and blocked gas outlet 2,
Combustion gas is the most cut-off.Use electric magnet 6, the regulating magnet 6 suction to iron ball 4 can be carried out by size of current is adjusted
