Description

[Detailed description of the invention] [Field of application and overview of the invention] The present invention relates to a box droplet, particularly a bottle droplet that can open and close a flow path within the bottle body by rotating a plug provided in the bottle body. This is intended to prevent the inconvenience of excessive external force being applied to the sealing part of the rotary valve during opening and closing operations by arranging the rotating part of the plug to surround and engage the lock body that accommodates the closure.

[Prior art and its problems] A gas bottle is housed in a box, and a plug provided in the bottle body is rotated to project into the opening of the box, thereby opening and closing a flow path in the bottle body. As such, it has already been disclosed in the official gazette of Utility Model Publication No. 48-3149. In this conventional type, as shown in Fig. 6, a closing member 1 is fixed to a box and paired around a rotating cylinder portion 21 provided at the upstream end of a plug 2. The flow path inside the gas tank can be opened and closed by the movement. In addition, by setting this rotation range to a predetermined value, the state in which the plug is pushed down into the box becomes the "closed" state, and conversely, the state in which the plug is rotated toward the opening of the box becomes the "open" state. This eliminates the inconvenience of the plug protruding from the wall when the gas is not in use.

However, in this conventional device, when the plug is repeatedly opened and closed by operating the plug, leakage is likely to occur in the seal between the closure 1 and the rotary cylinder portion 21. This means that when the plug 2 is rotated, the rotating cylinder portion 2
1 is subjected to an eccentric load, the pressure on the contact surface between the closing member 1 and the rotating cylinder portion 21 is not constant, and the wear on the sliding surface is not uniform. That is, the sealing failure occurs due to uneven wear of the sliding surfaces of the closing member 1 and the rotary cylinder portion 21, which serve as the sealing portions.

[Technical Problem] The present invention has a gas tank equipped with a rotary valve 10 such as a closure inside the box B, and by rotating a plug 2 provided in the gas tank, the valve can be rotated. In order to prevent leakage from occurring in the sealing part even if the plug 2 is repeatedly operated in a gas tank tank in which the flow path in the gas tank is opened and closed by rotating the valve train 10,
The technical problem is to prevent the operating force applied to the plug 2 from acting as an eccentric load on the seal portion of the rotary valve.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned technical problem is as follows. The closed cylindrical part 22 is fitted around the cylinder part 22 in a mating state, and an airtight means is provided between the open end of this cylindrical part 22 and the outer periphery of the pot body 3, and the rotary valve 10 and the cylindrical part 22 are integrated. The plug 2 is connected to the cylindrical portion 22 for rotation, and when the rotary valve 10 is rotated to the open position, the gas outlet through-hole 33 of the Kotuku body 3 communicates with the inside of the plug 2. The cylindrical portion 22 is provided with a communication hole 2a that allows the

[Operation] The above technical means of the present invention operates as follows.

The plug 2 is connected to a cylindrical portion 22, and this cylindrical portion is engaged with the rotary valve 10 so as to rotate together, so when the plug 2 is rotated, the rotary valve 10 is rotated. The flow path in the gas tank is opened and closed depending on the relationship between the gas tank main body 3 and the rotary valve 10. Further, when the rotary valve 10 is rotated to the open position, the plug 2 and the through hole 33 of the gas tank main body 3 are connected to each other by the communication hole 2a of the cylindrical portion 22 that fits externally into the downstream end cylindrical portion of the gas tank main body 3. is in communication and gas can be taken out from plug 2. Here, since the cylindrical portion 22 is rotated in a rotating relationship with the cylindrical body 3, the eccentric load generated by the rotating torque applied from the plug 2 to the cylindrical portion 22 is received by the cylindrical body 3. It will be. Therefore, when the rotary valve 10 is rotated by the rotation of the plug 2 to open and close the flow path, no eccentric load acts on the sliding surface of the rotary valve 10.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

On the rotating sliding surface which is the seal part of the rotary valve 10,
Since the eccentric load generated when operating the plug 2 is not applied, even if this operation is repeated over a long period of time, leakage is unlikely to occur in the seal portion of the rotary valve 10.

Moreover, since the external force applied to the plug 2 is received by the cock body 3 through the cylindrical part 22, even if an impact force is applied to the plug 2, there is no fear of damage to the rotary valve part.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

In this embodiment, as shown in Figs.
It is composed of a cylindrical part having a gas inlet 31 and a cylindrical main part 32 that is perpendicular to the cylindrical part and houses the rotary valve 10. It houses the valve train 10,
A through hole 11 is formed in the body on the upstream end side of the rotary valve 10, and this through hole 11 and the gas inlet 3 of the cock body 3 are connected to each other.
1, and furthermore, a rotary cylinder 12 with one end closed, which communicates with the opening at the downstream end of the rotary valve 10 and whose outer periphery is kept airtight by the main body 32, is attached to the rotary valve 10.
They are interlocking.

This rotating cylinder 12 is located at the end of the main body 32,
A cylindrical portion 22 connected to the plug 2 is rotatably fitted onto the end of the main body portion 32 so as to be coaxial with the rotary tube 12, and the cylindrical portion 22 and the rotary tube 12 are They are engaged with each other at the open end of the main body part 32, and when the plug 2 provided in the cylindrical part 22 is rotated, the cylindrical part 22 rotates integrally with the rotary valve 10 via the rotary cylinder 12. .

Further, the arrangement position of the through hole 11 formed in the rotary valve 10 is set in advance, and when the plug 2 is pushed into the box B, the through hole 11 is placed in the cylindrical portion 22.
When the plug 2 is rotated through a certain angle from this state to protrude from the box B, the through hole 11 and the gas inlet 31 are in communication with each other.

On the other hand, the hole 13 provided in the rotating cylinder 12 and the plug 2
The relationship between the through hole 33 provided in the main body portion 32 and
3 and the inside of the plug 2 are provided in the cylindrical portion 22 through a communication hole 2a.
Conversely, when the plug 2 is pushed into the box B, the hole 13 and the inside of the plug 2 are blocked by the wall surface of the main body 32 as shown in FIG. It's getting old. Therefore, in this device, when the plug 2 is rotated so as to protrude from the box B, the flow path in the gas tank becomes "open", and when the plug 2 is pushed in, this flow path is "closed". In order to realize the engagement between the cylinder part 22 and the rotating cylinder 12, in this embodiment, as shown in FIG.
The concave groove 14 provided on the end surface of the rotating cylinder 12 and the cylinder part 22
A protruding piece 23 provided on the end face of the plate is fitted into the protruding piece 23.

Next, in this embodiment, as shown in FIG. 5, the box B is closed with a cover plate 5, and an opening 51 is opened in the cover plate 5, and the plate-shaped operation knob 4 is exposed from this opening 51. I'm letting you do it. This operating knob 4 has one end fixed to the cylindrical portion 22 and is set almost parallel to the plug 2. In order to connect the socket 6 to the plug 2, the operating knob 4 is connected to the plug 2 as shown in FIG. The distance from the knob 4 is set sufficiently. Furthermore, a knob portion 41 is provided at the tip of the operating knob 4.

Therefore, when the gas tank is in the "closed" state, the operating knob 4 is in a state where the opening 51 is just closed.
The knob portion 41 is in a state of protruding from the upper surface of the lid plate 5. From this state, when the knob 41 is pinched and rotated as shown in FIG. 2, the flow path in the gas tank opens as described above.
Then, the plug 2 protrudes from the cover plate 5. In addition,
As shown in the figure, this plug 2 is equipped with a valve body 24 that opens when the socket 6 is connected, so that the gas circuit is not yet opened in this state. When the socket 6 is connected to the plug 2 in this state, the shaft 61 of the socket 6 pushes the valve body 24 to open the valve, thereby putting the downstream appliance connected to the socket 6 into the gas usage state. becomes.

In this embodiment, when the gas tank is "closed", not only the plug 2 is housed in the box B, but also the opening 51 of the lid plate 5 is closed by the operating knob 4, so that the plug 2 is housed in the box B. There is no need to worry about dirt or foreign matter getting into the unit.

In this embodiment, the rotary valve 10 is a cylindrical valve, but it may be a closure similar to the conventional example.
