Hereinafter, the structure of the magnetic circuit breaker 10 will be described with reference to the left side of FIG. 1 as an upper side and the lower side of FIG. 1 as a lower side for convenience of explanation. And the cylindrical fixing portion 14 is provided on the lower side of the magnet 11 at regular intervals. The support 12 is a structure protruding upward from the fixing portion 14 so as to support the magnet 11 so as not to be detached but a plurality of protrusions are formed on the upper portion of the fixing portion 14. [

The magnet support plate 13 is provided to support the magnet 11 on the lower side of the magnet 11. The magnet support plate 13 is disposed on the upper surface of the magnet 11 and inserted from the lower side of the fixing portion 14, (12) protruding from the fixing portion (14) so as to be engaged and fixed. At this time, the end of the supporter 12 is bent inward so as to be positioned inside the outer diameter of the magnet 11, and the magnet is caught and fixed so as not to be released to the outside.

The magnet support plate 13 may further include a guide 16 projecting from a side surface of the magnet support plate 13 and extending upward. The guide 16 serves to guide the position of the magnet 11 so that the magnet 11 is positioned at the center without moving left and right when the magnet is placed on the magnet support plate 13.

The shield plate 15 is a plate made of a metallic material and is positioned below the magnet support plate 13 and attached to the bottom surface of the magnet support plate 13 by the magnetic force of the magnet 11. The size of the blocking plate 15 is not limited to the size and shape as long as the inside of the plurality of supports 12 can be freely moved up and down. 2, since the shield plate 15 must be able to receive a resistance according to the flow of the fluid, it is preferable that the shield plate 15 is larger than the size of the magnet 11, Any size can be used as long as it can be reciprocated from the inside, and its shape is also not limited.

1 and 2, the magnet support plate 13 has a triangular shape, but the shape of the magnet support plate 13 is not particularly limited. In this embodiment as shown in the figure, as described later, the fluid is applied to the magnet 11 and the magnet support plate 13 so that the fluid can come into direct contact with the shield plate 15 positioned next to the magnet support plate 13, The support plate 13 is configured in a triangular shape so that the inflow fluid is directly applied to the area of the blocking plate 15 indicated by purple color as shown in FIG.

Of course, although not shown, the magnet 11 may be fixed to the plurality of supports 12 without the magnet supporting plate 13, and the blocking plate 15 may be positioned immediately below the magnet Of course it is. At this time, it is also preferable to form a protrusion at a position corresponding to the lower side of the magnet on the inner side of the plurality of supports 12 so that the blocking plate 15 is positioned at a predetermined distance without directly touching the magnet 11 Do.

3, the ball valve body 20 includes a ball 31 at the center, a spindle 33 connected to the upper portion of the ball 31, and a handle 32 connected to the spindle An inlet 21 through which the fluid flows into the both sides of the ball 31 and an outlet 22 through which the fluid flows out are connected to the inlet 21 and the outlet 22, A fixing groove 24, an inner rim portion 25 and a distal end portion 26 are further provided on the inner diameter portion on the side of the inflow opening 21 in a normal ball valve body having a flow path 23 . Since the conventional ball valve is well known in the related art, a detailed description thereof will be omitted.

As shown in FIG. 3, the fixing groove 24 is formed along the inner diameter portion on the inner diameter side of the inlet 21 side and formed in a direction parallel to the flow direction of the fluid. The magnetic circuit breaker 10 is fixedly coupled to the inner surface of the ball valve body 20 by inserting the fixing portion 14 of the magnetic circuit breaker 10 into the fixing groove 24. [ 4, the magnetic circuit breaker 10 is coupled to the inner surface of the ball valve body 20.

The inner rim portion 25 has a rim structure provided inside the fixing groove 24 when the fixing groove 24 is formed. The distal end portion 26 is a portion formed flat on the distal end of the inner rim portion 25 on the side of the inlet 21.

4 shows a state where the fixing portion 14 of the magnetic circuit breaker 10 is fitted and fixed to the fixing groove 24. As shown in FIG. At this time, the blocking plate 15 is attached to the magnet side, that is, toward the magnet supporting plate 13, by the magnetic force of the magnet 11.

In this state, as shown in FIG. 5, when the fluid flows at a normal conveying pressure, the fluid is introduced into the space between the blocking plate 15 and the fixing portion 14, which is visible in FIGS. 1 and 2 Flows through the flow path (23), and flows to the outlet (22). In this case, the fluid is also applied to the area of the blocking plate 15 indicated by the purple color area in FIG. 2, so that the blocking plate 15 does not fall off to the pressure of the fluid in the case of a normal transfer pressure. If necessary, select a magnet with a magnetic force of an appropriate size so that it can be used.

However, if there is a breakage of the piping, a defect caused by an impact at the joint portion between the pipe and the piping, or a fluid leakage accident such as a gas leakage accident caused by intentional leakage, the fluid suddenly flows out to the pipe, The speed of the fluid increases. That is, the pressure of the fluid flowing in the ball valve is increased. In this case, the fluid presses the area of the blocking plate 15 indicated by the purple color area of FIG. 2, because a large pressure is applied due to the leakage of the fluid, not the usual fluid transfer pressure. The blocking plate 15 is pushed and brought into close contact with the distal end portion 26 of the inner rim portion 25 as shown in Fig. 6, exceeding the magnitude of the magnetic force of the magnet 11. That is, the blocking plate 15 blocks the flow of the fluid by blocking the flow path 23.

Therefore, in order to prevent the flow path 23 from exceeding the magnetic force of the magnet 11 in response to an increase in pressure in the event of a gas leakage accident as described above, Select a magnet to use.

As shown in FIG. 2, a portion of the purple-colored portion, which flows from the inlet 21 side, directly applies pressure to the blocking plate 15. In order to appropriately form the area of the blocking plate 15, It is preferable that the shape of the magnet support plate 13 is formed into a triangular shape as shown in the figure. However, the shape is not limited thereto, and the shape and size are not particularly limited as long as the portion where the fluid directly applies pressure to the blocking plate 15 is suitably ensured and the object of the present invention can be achieved.

As described above, when the blocking plate 15 is in close contact with the distal end portion 26 to block the fluid by blocking the fluid channel 23, the fluid leakage is restored and normalized The blocking plate 15 that is in close contact with the distal end portion 26 due to the pressure of the fluid may be applied to the magnetic force of the magnet 11 by the pressure of the fluid, To be returned to the original position shown in Fig. 4 or Fig.

Due to the above-mentioned function of the present invention, even if a gas leakage accident occurs in a building in the event of a disaster such as an earthquake, the gas is automatically shut off in the ball valve according to the present invention, thereby preventing dangerous accidents such as an explosion accident have.

3 and 4, the distal end portion 26 may be stepped so that the outer diameter portion has a lower height than the inner diameter portion. In this case, the inner diameter portion of the distal end portion 26, that is, the inner upper portion is a portion to which the blocking plate 15 is closely attached, and the outer diameter portion is a portion where the lower end portion of the support base 12 is seated . The support base 12 is seated on the outer stepped portion of the distal end portion 26 so that the magnetic circuit breaker 10 can be more firmly fixed to the ball valve body 20.
