ものである。 The gas tank of the present invention includes a rotary valve 3 that opens and closes a gas passage 2 in the gas passage 2 of the gas tank body 1, and a rotary valve that is housed in a recess 46 that serves as a gas flow path in the rotary valve 3 so as to be able to move up and down. a second valve means A for opening and closing the side gas outlet 50 of the rotary valve 3; and a second magnet 17 provided on the upper part of the second valve means A and located at the axis of the rotary valve 3.
and a first magnet 14 which is provided above the rotary valve 3 in the Kotuku body 1 and is rotatable together with the rotary valve and is slidable in a direction perpendicular to the axis of the rotary valve 3; A first pressing part is provided in the Kotoku main body 1 and pushes the first magnet 14 in one direction when the rotary valve 3 is fully opened or almost fully opened to position one half of the first magnet 14 at the axis of the Kotoku main body 1. 54, and when the first magnet 14 is pressed by the first pressing part 54, the first magnet 14 and the second magnet 17 are attracted or repelled, and the rotary valve 3 is closed by the second valve means A. The side gas outlet 50 is set to be open. The present invention will be explained in detail below with reference to Examples. A rotary valve 3 having a concave portion 46 opening laterally and downwardly is rotatably fitted into the main body 1, and a cylinder body 48 is attached to a lower opening 47 of the concave portion 46 of the rotary valve 3. An inner flange 49 for a valve receiver is provided around the upper end of the body 48 facing inward. Recess 4
A second valve means A is installed inside the valve 6 so as to be movable up and down. The second valve means A includes a second valve 4 made of a ball;
The second valve 4 is configured with a side opening case 16 in which the second valve 4 is freely housed, and the second valve 4 loosely fitted in the case 16 allows the side gas outlet 50 of the rotary valve 3 to be opened.
A valve port 19 made of an elastic material provided in the valve opening 19 is opened and closed. A second magnet 17 is disposed at the top of the case 16, and a spring material 18 urges the case 16 downward so that the lower end of the case 16 hits the inner flange 49 and prevents it from falling any further. There is. When the case 16 is in contact with the lower inner flange 49, the second valve 4 corresponds to the valve port 19 provided at the side gas outlet 50 of the rotary valve 3, and closes the valve port 19 by gas pressure. It's becoming like that. Therefore, even if the gas outlet 50 of the rotary valve 3 and the gas outlet 58 of the cock body 1 are in communication, gas will not flow if the second valve 4 closes the valve port 19. Two parallel protrusions 51 are protruded from the upper surface of the rotary valve 3 to face each other, and a first magnet 14 is placed between the protrusions 51 along the protrusions 51 as shown in FIG. It is placed so that it can be moved freely. In other words, the first magnet 14 has parallel protrusions 51
Although the rotary valve 3 rotates together with the rotary valve 3 under the control of the rotary valve 3, it is slidable along the protrusion 51 in a direction perpendicular to the axis of the rotary valve 3. 52 in the figure is the first
This is an outer cover body for the outside of the magnet 14. A C-shaped spring 53 is attached to the inner wall of the Kotuku body 1.
One free end of the letter-shaped spring 53 protrudes inward to become a first pressing part 54, and the other free end also projects inward to become a second pressing part 55. Here, the second magnet 17 is arranged so that its upper and lower parts have different polarities, and the first magnet 14 is arranged so that one half in the left and right direction and the other half have different polarities. be. Therefore, when the rotary valve 3 is in a closed state or a half-open state, the first magnet 14 is pressed by the second pressing portion 55 of the C-shaped spring 53, and the first magnet 14 is located on the axis of the rotary valve 3. Only one half of 14 (i.e., either the N pole or the S pole) is located, and the other half (i.e., the other of the N pole or the S pole) is located eccentrically from the axis. I will do it. Therefore, if the upper pole of the second magnet 17 is set to the N pole, the N pole of the first magnet 14 should be set to be on the axis of the rotary valve 3 in the closed and half-open states. The first magnet 14 and the second magnet 17 repel each other, and the second magnet 17 is pushed downward by the spring force of the spring material 18, so that the second valve 4
The valve port 19 closes accordingly. Here, when the rotary valve 3 is rotated to a fully open or almost fully open state, the first pressing part 54 pushes the first magnet 14 and slides the first magnet 14.
The other pole of the magnet 14 (S pole in the embodiment) is the rotary valve 3
The second magnet 17 is pulled upward against the spring force of the spring member 18 by being attracted to the upper pole (the N pole in the embodiment) of the second magnet 17;
The second valve 4 opens the valve port 19. Therefore, the case 16 moves upward and the second valve 4 opens only when the rotary valve 3 is fully open or almost fully open. For this reason, even if the rotary valve 3 is turned, in the half-open state, the side gas outlet 50 and the gas outlet 5 are connected as shown in FIG.
8, but the valve port 19 of the side gas outlet 50 is closed by the second valve 4. The rotary valve 3 is rotated via a pin 9 by pushing and turning a knob 10. A shut-off valve ball 24 is freely movable inside the cylinder 48, and the shut-off valve ball 24 can be used to prevent the rubber hose connected to the plug 20 from coming off, or when gas is spewing out without being ignited. When gas flows under load or in a high flow rate state, the gas pressure rises and presses against the lower surface of the valve receiver inner flange 49 to close the upper opening of the cylinder body 48. Therefore, the cylindrical body 48 containing the shutoff valve ball 24 serves as the emergency shutoff mechanism 21. When resetting, the rotary valve 3 is closed, the case 16 is lowered, and the cutoff valve ball 2 is moved by the protrusion 56 on the lower surface of the case 16.
4 to fall downward, and the cutoff valve ball 24 dropped downward is received by a stopper pin 36 provided at the bottom of the cylindrical body 48 to prevent it from falling any further. By the way, the emergency shutoff valve mechanism 21 operates only when gas pressure above a certain level is received and closes the gas passage 2, so it will not work if the gas hose is disconnected or the gas does not ignite only when the rotary valve 3 is fully open or almost fully open. It will be activated when gas is released. Therefore, the emergency shutoff mechanism 21 does not operate when the rotary valve 3 is between fully closed and fully open (that is, in a half-open state). However, in the case of the present invention, the second valve means A opens the gas passage 2 only when the rotary valve 3 is fully open or almost fully open, so gas does not flow in the half-open state. Therefore, gas will not flow in the half-open state,
Even when the gas hose is fully open or almost fully open, if the gas hose is disconnected or gas is released without igniting, the emergency shutoff mechanism 21 closes. The gas will not leak out under any circumstances (except when
It is particularly effective in preventing gas suicide, etc. In the above embodiment, the second valve means A is opened by the attraction between the first magnet 14 and the second magnet 17, but the second valve means A is opened by the repulsion between the first magnet 14 and the second magnet 17. The second valve means A may be opened.

クト化できるものである。 In the case of the present invention, as described above, there is a rotary valve that opens and closes the gas passage in the middle of the gas passage in the main body of the rotary valve, and a rotary valve that is housed in a recess that becomes the gas flow path inside the rotary valve so as to be able to move up and down. Since the second valve means for opening and closing the side gas outlet is provided, the gas passage of the Kotuku main body is closed and closed by a double valve, which is highly safe, and the second valve means A second magnet is provided at the top of the rotary valve and located at the axis of the rotary valve; A first magnet that is slidable in orthogonal directions, and a first magnet that is provided inside the Kotuku main body and pushes the first magnet in one direction when the rotary valve is fully opened or almost fully opened, and one half of the first magnet is attached to the shaft of the Kotuku main body. and a first pressing part for positioning the first magnet at the center, and when the first pressing part presses the first magnet, the first magnet and the second magnet attract or repel, and the second magnet
Since the side gas outlet of the rotary valve which has been closed by the valve means is set to be opened, simply by rotating the rotary valve, when the rotary valve is fully opened or almost fully opened, the second gas outlet is opened.
The valve means can be opened and can be easily operated, and gas does not flow from the Kotuku body when the rotary valve is half open, but only when it is fully open or almost fully open. It is safe, and since the second valve means can be opened and closed by a magnet, an airtight structure can be created between the second valve means and the first magnet, which is the means for moving the second valve means, thereby preventing gas leakage. There is no risk of
Since the valve means is provided and the first magnet is provided on the upper surface of the rotary shaft, the second valve means and its opening/closing mechanism can be arranged on the rotary valve in the vertical direction of the rotary valve, and the whole can be made compact. .
