BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-contact type safety valve box having a handle portion that is easy to attach and detach, and more particularly, And more particularly to a noncontact opening and closing type safety valve box provided with a handle that can be easily opened and closed to open and close a passage of a pipe in which a passageway through which a fluid passes manually by an operator outside the valve box is formed.

Generally, a valve is used as movable furniture in which a passage through which a fluid passes is formed so that the passage can be opened and closed to pass, block or control the fluid.

That is, the valve stem contacts the valve seat to block the flow passage, or the valve stem contacts the valve seat to open the flow passage, thereby opening and closing the passage through which the fluid flows in the pipe.

In order to make the valve stem contact with or separate from the valve seat, a driving device for moving the valve stem is provided, and an automatic valve in which the valve stem is driven by electricity, hydraulic pressure, pneumatic pressure or the like is mainly used.

Such an automatic valve typically requires a motor and a driving device such as a motor. In order to operate the motor, there is a problem in that an electric wire, a hydraulic pipe, and a pneumatic pipe are additionally connected.

In the case of a solenoid valve which is mainly used as a small valve, in order to drive the valve stem in a direction opposite to the elastic force of the spring, a magnetic field is continuously applied to the coil surrounding the electromagnet There is a problem in that electric power must be supplied in the same manner as the above-mentioned automatic type valve.

As described above, in the case of the conventional valve, it is basically necessary to supply electric power from the driving source, and there is also a problem that when it is used in a flammable environment due to a heat generation problem, it is directly exposed to a safety accident such as an image or fire.

In order to solve such a problem, Korean Utility Model No. 20-0428959 discloses a method of forming a valve box by using concrete, while keeping the airtightness by using a circular cover which is usually used, There is disclosed a valve box in which at least two support flanges are formed on at least two of the four sides of the lower region of the box and at least a plurality of lid supporting members are provided so as to protrude upward from the outside of the opening at predetermined intervals .

This valve box has the effect of preventing the valve box, the pipes and the valves from being broken and preventing the cover from being separated from the openings by preventing the valve box from tilting to one side in accordance with the change of the earth pressure and the ground layer in the underground. However, There is a possibility that a safety accident in which the operator is exposed to the leaked gas in the opened state may occur, and the leaked gas may be diffused to the outside in the state where the valve box is opened.

The valve 20 is installed at the middle or the end of the pipe 10 in order to block the flow of the fluid flowing through the pipe 10 or adjust the flow rate and pressure. The valve structure is the same / similar. However, in the embodiment of the present invention, the valve 20 has a structure for opening and closing the passage of the pipe 10 by the rotation action of the valve rod 21. [

The valve box 100 is a means for sealing the valve 20 and preferably has a hexahedron shape and hollow inside. The valve box 100 penetrates one side and the other side of the valve box 100, In this case, a valve 20 connected to the piping is positioned inside the valve box 100.

It is preferable that a packing member is provided at a joint between the one side and the other side of the valve box 100 through which the piping 10 penetrates to maintain airtightness so that the fluid inside does not leak out.

A recessed depressed groove is formed on an outer upper surface of the valve box 100 so as to surround the second rotating body 300 so that the second rotating body 300 can be seated.

It is preferable that the valve stem 21 of the valve 20 located inside the valve box 100 is provided in a direction perpendicular to the center of the seating groove formed on the upper surface of the valve stem 100 Do.

The first rotating body 200 is connected to an end of the valve rod 21 and rotates in conjunction with self rotation to rotate the valve rod 21. The first rotating body 200 has a circumference corresponding to the circumference of the seating groove And has a disk shape.

The first rotating body 200 is rotatably connected to an end of the valve stem 21, and a plurality of depressed depressions are formed in an inward direction along a periphery of the upper surface of the valve body, Respectively.

In particular, one of the magnets fixed to one of the plurality of grooves recessed along the periphery of the upper surface of the first rotating body 200 is disposed in the circumferential direction of the upper surface of the first rotating body 200, And is arranged to have a polarity different from that of the magnet fixedly installed in the groove adjacent in the direction opposite to the circumferential direction of the top surface of the one rotating body 200. [

The first rotating body 200 is disposed horizontally with the upper surface of the valve box 100 inside the valve box 100.

The second rotatable body 300 is a means for rotating the first rotatable body 200 by interlocking with the self-rotation of the first rotatable body 200, And is disposed horizontally with respect to the first rotating body 200 with reference to the upper surface of the valve box 100. [

Particularly, one of the magnets fixed to any one of the plurality of grooves recessed along the bottom edge of the second rotating body 300 is disposed in the circumferential direction of the lower surface of the second rotating body 300, Are arranged so as to have polarities different from those of a magnet fixedly installed in a groove formed at a position close to the lower edge of the lower rotating body 300 in a direction opposite to the circumferential direction.

Accordingly, the magnets fixed to the second rotating body 300 and the magnets fixed to the first rotating body 200 have polarities different from each other, and one pair of magnets, to which attraction force acts, The magnets fixed to the second rotating body 300 rotate integrally as the second rotating body 300 rotates by an external force in a state where the first rotating body 200 And the magnet having the other polarity are opposed to each other, so that the repulsive force acts to rotate the first rotating body 200.

The handle portion 400 is a means for rotating the second rotating body 300 interlocked with the first rotating body by manually rotating the handle portion 400. The handle portion 400 is fixedly installed through the center of the upper surface of the second rotating body 300 And a lever 420 connected to the rotating shaft 410 and configured to rotate the rotating shaft manually by being held by an operator.

The rotation shaft 410 is a circumferential long and large shaft fixedly installed through the center of the upper surface of the second rotating body 300, and the lever 420 is fixed to the upper end thereof.

The operator grips and rotates the lever 420, so that the rotation shaft 410, to which the lever 420 is fixed, rotates and rotates.

When a magnetic field is externally applied, Examples of typical paramagnetic materials include aluminum, chromium, chromium chloride, manganese oxide, molybdenum, titanium, zirconium and the like.

Semi-magnetism is nonpermanent and has a very weak form of magnetism, which is formed only during the application of a magnetic field from the outside. It is induced by changing the orbital motion of electrons by an externally applied magnetic field. Representative semiconductors include aluminum oxide, copper, Gold, mercury, silicon, silver, sodium chloride, and zinc.

These paramagnetic and semi-magnetic bodies are classified as nonmagnetic because their linear flux density is almost the same as in vacuum and they are magnetized only when an external magnetic field is applied.

The non-contact type safety valve box of the present invention includes a valve box 100 that seals a valve 20 installed in a pipe 10 so that even if a gas leaks through the valve 20, It is possible to open and close the passage of the pipe 10 in which the passageway through which the fluid passes manually by the operator outside the valve box 100 can be prevented, A sensor 500 for sensing a fluid leaking inside the valve box 100 and transmitting a sensed signal so that an operator can detect that the gas leaks to the outside of the valve box 100, And a leakage display unit 600 installed.

The detection sensor 500 is installed inside the valve box 100 to generate an electric signal relating to leakage information of the fluid and transmits the generated electric signal to the leakage display unit 600.
