The water theft prevention cover 1 of the prior art is to cover the water faucet 2 with the water theft prevention cover 1, put the chain 3 into the key loop 4 attached to the water theft prevention cover 1, and lock it with the key 5. However, if the water theft prevention cover 1 and the chain 3 were destroyed, the water flow could be easily changed. Therefore, it was necessary to further improve the security aspect.

An object of the present invention is to prevent an outsider from rotating a valve body without permission to change the flow of the fluid, contrary to the intention of a user who receives a fluid such as water, in fluid management. It is an object of the present invention to provide a cylinder lock type fluid valve device capable of improving security.

In order to achieve the above object, the present invention has a valve case provided with an inflow port into which a fluid flows in and an outflow port into which the fluid flows out, and is rotatable about a predetermined axis in the valve case. It is housed in a valve body provided and capable of interrupting the flow of the fluid by rotation, a rotor case fixed to the valve case and provided with a substantially cylindrical rotor storage hole, and the rotor storage hole of the rotor case. The rotor has a rotor that can rotate around the axis integrally with the valve body, and the rotor has a key insertion hole extending in the axis direction and a key insertion hole that communicates with the key insertion hole in the radial direction. The rotor case includes a plurality of formed tumbler storage holes and a plurality of tumblers that are accommodated in a radial direction with respect to the plurality of tumbler storage holes. A key composite that is provided with a plurality of tumbler storage recesses that communicate with each other in the radial direction and is inserted into and removed from a keyhole that communicates with the keyhole provided at one end of the rotor in the axial direction. At least two of the tumbler storage holes are arranged in a row along a direction parallel to the axis to form a tumbler storage hole row, and a plurality of tumbler storage hole rows are arranged at equal angular intervals in the circumferential direction. A plurality of keys are arranged at a plurality of locations in the circumferential direction, and the key complex is provided with the same number of keys as the plurality of tumbler storage hole rows at the same angle spacing as the angle spacing of the plurality of tumbler storage hole rows . When the key complex is inserted into the keyhole, the concave-convex shape provided in each of the plurality of key portions has a portion, and the concave-convex shape provided in each of the plurality of key portions is formed in the plurality of tumbler storage holes of the corresponding tumbler storage hole row . A cylinder lock type in which the key composite inserted in the keyhole can be rotated together with the rotor by substantially matching the positions of the free ends of the plurality of housed tumblers with the outer peripheral surface of the rotor. In a fluid valve device, when the key complex is removed from the keyhole, each of the plurality of key portions is housed in the plurality of tumbler storage holes of the corresponding tumbler storage hole row. By making the position of the free end portion of the tumbler inconsistent with the outer peripheral surface of the rotor, the rotor cannot be rotated, and the tumbler storage hole row corresponding to the number of the plurality of tumbler storage hole rows is arranged. The angular interval is set to 60 °, 45 °, or 30 ° corresponding to the target adjustment interval of the flow amount of the fluid adjusted by the rotation of the valve body, and the uneven shape provided in each of the plurality of keyholes. Correspondingly, in each of the plurality of tumbler storage hole rows, the free end of the plurality of tumblers housed in the plurality of tumbler storage holes provided in each tumbler storage hole row. By making the positions of the portions identical to each other, after inserting the key complex into the keyhole, 360 ° is divided by the number of tumbler storage hole rows, and the angle is equal to the angle interval. It is characterized in that the key complex can be pulled out from the keyhole by rotating it by a certain 60 °, 45 °, or 30 ° .

In the fluid valve device of the present invention, a valve body is provided in a valve case provided with an inlet and an outlet. The valve body can rotate around a predetermined axis, and the rotation can interrupt the flow of a fluid such as water or gas that flows in from the inlet and flows out from the outlet.

In the fluid valve device of the present invention, the mechanism for rotating the valve body is configured as a so-called cylinder lock type. That is, the rotor case is fixed to the valve case, and the rotor that can rotate integrally with the valve body is housed in the rotor storage hole provided in the rotor case.

Correspondingly, the key complex inserted into the key insertion hole of the rotor includes a plurality of key portions. These plurality of key portions are provided at the same angle interval as the above-mentioned angle interval, and are provided in the same number as the number of the above-mentioned plurality of tumbler storage hole rows .

In the fluid valve device of the present invention, according to the above configuration, when the key composite is inserted into the keyhole, the uneven shape of each key portion changes the position of the free end portion of each corresponding tumbler to the outer peripheral surface of the rotor. By substantially matching, a so-called cylinder lock is formed that allows both the key complex and the rotor to rotate.

This makes it impossible to rotate the rotor and valve body unless the key complex is inserted into the keyhole of the rotor. As a result, it is possible to prevent other outsiders from rotating the valve body and changing the flow of the fluid without permission, contrary to the intention of the user (or a person concerned with the fluid) who receives the fluid. , It is possible to improve the security in fluid management.

However, in order to finely adjust the distribution amount, the angle interval A is 45 °, 30 °, or the like. It doesn't matter if there is one. The angle interval A is more preferably 30 °. In that case, the key complex 2 can be inserted and removed every time the key complex 2 is rotated by 30 °.

<Effect of embodiment>
In the cylinder lock type fluid valve device 1 of the present embodiment, the valve body 8 is provided in the valve case 7 provided with the inflow port 5 and the outflow port 6. The valve body 8 can rotate around a predetermined axis, and the rotation can interrupt the flow of a fluid such as water or gas that flows in from the inflow port 5 and flows out from the outflow port 6.

In the cylinder lock type fluid valve device 1 of the present embodiment, the mechanism for rotating the valve body 8 is configured as a so-called cylinder lock type. That is, the rotor case 9 is fixed to the valve case 7, and the rotor 11 that can rotate integrally with the valve body 8 is housed in the rotor storage hole 10 provided in the rotor case 9. Inside the rotor 11, there are a key insertion hole 12 extending in the axial direction, a plurality of tumbler storage holes 13 extending in the radial direction, and a tumbler 14 arranged in each tumbler storage hole 13 so as to be able to advance and retreat in the radial direction. The rotor case 9 is provided with a plurality of tumbler storage recesses 15 that communicate with each tumbler storage hole 13 in the radial direction.

At this time, in the rotor 11, at least two tumbler storage holes 13 are arranged in a row along the direction parallel to the axis to form a tumbler storage hole row 17, and the tumbler storage hole rows 17 are provided in a plurality of rows. ing. The plurality of tumbler storage hole rows 17 are arranged at equal intervals in the circumferential direction with a predetermined angular interval A. Correspondingly, the key complex 2 inserted into the key insertion hole 12 of the rotor 11 includes a plurality of key portions 3. These plurality of key units 3 are provided at the same angle interval as the angle interval A, and are provided in the same number as the number of the plurality of tumbler storage hole rows 17.

Then, in the cylinder lock type fluid valve device 1 of the present embodiment, according to the above configuration, when the key composite 2 is inserted into the keyhole 16, the uneven shape D of each key portion 3 is free of the corresponding tumbler 14. A so-called cylinder lock is formed in which the position of the end portion 18 is substantially aligned with the outer peripheral surface 19 of the rotor 11 so that both the key complex 2 and the rotor 11 can rotate.

As a result, the rotor 11 and the valve body 8 cannot be rotated unless the key complex 2 is inserted into the keyhole 16 of the rotor 11. As a result, it is possible to prevent other outsiders from rotating the valve body 8 without permission to change the flow of the fluid, contrary to the intention of the user (or a person concerned with the fluid) who receives the fluid. It is possible to improve the security in fluid management.

Further, in the cylinder lock type fluid valve device 1 of the present embodiment, in particular, due to the above-mentioned cylinder lock configuration, after the key composite 2 is removed from the keyhole 16, the uneven shape D of each key portion 3 disappears. As a result of the position of the free end 18 of each corresponding tumbler 14 not matching the outer peripheral surface of the rotor 11, the rotor 11 can be made non-rotatable.

When 2 is inserted into the keyhole 16 to rotate the rotor 11 and the valve body 8, at least 360 ° can be stored in the number of key portions 3a to 3 (or tumbler storage) even if the rotor 11 and the valve body 8 are not rotated once by 360 ° in the circumferential direction. The number of the hole rows 17; hereinafter, appropriately referred to as “the number of the key portions 3 and the like”) can be rotated by an angle, and then the key complex 2 can be extracted from the keyhole 16. That is, for example, if the number of key portions 3 and the like is 4, the key complex 2 can be inserted into the keyhole 16 and then turned 90 ° (= 360 ° / 4), and then the key complex 2 can be removed from the keyhole 16. can. Similarly, if the number of the key portions 3 and the like is 6, it is 60 °, if it is 8, it is 45 °, and if it is 12, it is turned by 30 °, and then the key complex 2 can be extracted from the keyhole 16. ..

As described above, the minimum angle required for inserting the key complex 2 into the keyhole 16 and extracting the rotor 11 and the valve body 8 after rotating them is determined by the number of the key portions 3 and the like. Therefore, in the present embodiment, in particular, the angle interval A between the key portion 3 and the tumbler storage hole row 17, in other words, the number of the key portion 3 and the tumbler storage hole row 17, is adjusted to the target adjustment interval of the fluid flow rate. It is determined corresponding to. As a result, for example, if it is sufficient to adjust the distribution amount relatively roughly, the number of the key portion 3 and the tumbler storage hole row 17 is set small, and if the distribution amount is to be finely adjusted, the key portion 3 and the tumbler are set to a small number. The number of storage hole rows 17 may be set to be large. That is, it is possible to flexibly respond to the needs of the user (or a person concerned with the fluid) who receives the fluid.
