Combination of each component configured as described above is as shown in FIG.

Hereinafter, the operation of the present invention will be described with reference to the drawings.

First, when the power supply is cut off, that is, when the power supply is not supplied, as shown in FIG. 6, the electromagnetic force is not generated in the coil body 300 and the second magnetic body 310. And since the outflow does not pass through the conduit of the connector 600, the gas supply is blocked.

In this case, when the power supply is cut off, that is, when there is a power failure or a safety accident occurs, in case of a safety accident, the supply of gas must be cut off naturally. Since the supply must be possible, first, the supply of the gas will be described.

FIG. 5 illustrates a case where power is supplied. FIG. 5 will be described as an example.

That is, when the power is cut off due to a power failure or the like, when the user presses the pressure bar 100, the lifting housing 200 is lowered, and the lowering of the lifting housing 200 is a component of the lifting housing 200. The cylinder 210, that is, the first inner cylinder 211 and the second inner cylinder 212 is to be lowered along the outer cylinder 220.

In this case, the first magnetic body 230 is naturally lowered and at the same time, the third magnetic body 510 seated on the upper end of the pressure rod 500 provided in the fixed cylinder 400 having the opposite pole is the first magnetic body ( 230 is lowered together with the end to enable the lowering of the pressure rod 500.

As such, the lowering of the pressing rod 5000 lowers the opening / closing member 710 of the opening and closing means 700, which eventually closes the gap between the sealing protrusion 650 and the opening and closing member 710 as shown in FIG. 5. To generate gas.

Next, the following describes the supply of gas automatically by supplying power.

First, when power is supplied, an electromagnetic force is generated between the second magnetic body 310 and the coil body 300 to automatically lower the lifting housing 200, and the lowering of the lifting housing 200 is the lifting housing 200. The inner cylinder 210 which is a component of the first inner cylinder 211 and the second inner cylinder 212 is lowered along the outer cylinder 220 and consequently the lowering of the pressure bar 100 is made.

In this case, the first magnetic body 230 is naturally lowered and at the same time, the third magnetic body 510 seated on the upper end of the pressure rod 500 provided in the fixed cylinder 400 having the opposite pole is the first magnetic body ( 230 is lowered together with the end to enable the lowering of the pressure rod 500.

As such, the lowering of the pressing rod 5000 lowers the opening / closing member 710 of the opening and closing means 700, which eventually closes the gap between the sealing protrusion 650 and the opening and closing member 710 as shown in FIG. 5. To generate gas.

At this time, when the power supply is cut off, the opening and closing member 710 may be naturally lifted by the elastic force, that is, the restoring force of the elastic member 730, and the rise of the opening and closing member 710 may be in contact with the sealing protrusion 650. In this case, the supply of gas is blocked as shown in FIG. 6.

As described above, the present invention has a structure that is simpler than the conventional prior art and its operation is also simple, so that the compactness of the product is possible, and the valve is completely shut off when the power supply is cut off by completely blocking the leakage of gas or fluid. The response speed is further improved to minimize safety accidents, and the sealability, durability, automatic shutoff force, noise, etc. are greatly improved by completely preventing the leakage of gas, and the damage rate of components due to structural simplification is significantly lowered to extend the life. To make it possible.
