[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 to 3, the gas stopper 1 includes a main body 10. Inside the main body 10, an inflow path 11 opening at one end face (the left end face in FIG. 1) and an outflow path 12 opening at the other end face are formed. A plug housing hole 13 is formed between them.

A connection device 20 is provided at the opening of the inflow channel 11. Since the connecting device 20 is a known device, its description is omitted, but a flexible gas pipe (not shown) connected to a main plug (not shown) is connected to the connecting device 20.
Is connected to the inflow path 11. Therefore, gas flows into the inflow passage 11 from the flexible gas pipe. Instead of the connection device 20, a tapered female screw portion may be formed on the inner peripheral surface of the opening of the inflow passage 11, and a tapered male screw portion of an iron gas pipe may be screwed into the tapered female screw portion. Alternatively, instead of the connection device 20, a joint member similar to the joint member 30 described below may be provided.

A joint member 30 is rotatably provided on the outer periphery of the right end of the main body 10 where the outflow passage 12 opens. The joint member 30 has a tapered female screw portion 31 communicating with the outflow channel 12. By screwing the connecting portion G of the gas appliance into the tapered female screw portion 31, the outflow channel 12 and the inflow channel of the gas appliance are connected. Ga communicates through the joint member 30. As for the joint member 30, a connection device similar to the connection device 20 may be used instead. Alternatively, a tapered male screw portion may be formed on the outer peripheral surface of the joint member 30, while a tapered female screw portion may be formed in the inflow passage Ga, and these may be screwed together.

An inspection hole 14 is formed in one side of the main body 10 (the upper side in FIG. 1). This inspection hole 1
Reference numeral 4 is for checking whether there is gas leakage between the main cock (not shown) and the gas appliance, and between the gas cock 1 and the gas appliance, and the mechanism is well known. The detailed description is omitted because it is the same as the above. The inspection hole 14 is closed by the stopper 40 except during the inspection.

A stopper 50 is accommodated in the stopper accommodating hole 13. The stopper 50 is rotatable between a closed position shown in FIG. 1 and an open position rotated by approximately 90 ° from the closed position. The inflow path 11 and the outflow path 12 are shut off by the plug 50. When the plug 50 is turned to the open position, the inflow channel 11 and the outflow channel 12 communicate with each other through the through hole 51 of the plug 50.

A branch hole 15 is formed in a side portion (lower side portion in FIG. 1) of the main body 10 which faces in a direction orthogonal to the rotation axis of the plug 50. The branch hole 15 is used when adding a new gas appliance, and one end of the branch hole 15 is opened on the inner peripheral surface of the inflow passage 11. Therefore,
Gas always flows into the branch hole 15 irrespective of the rotational position of the plug 50, that is, regardless of whether the gas plug 1 is open or closed. The other end of the branch hole 15 opens to the side surface of the main body 10.

A mounting portion 60 is provided on the side of the main body 10 where the branch hole 15 opens. This mounting part 60 is
When a new gas appliance is added, the joint 80 or 90 described later is attached to the main body 10. The attachment plane 61 is orthogonal to the rotation axis of the plug 50, and is formed on the attachment plane 61. And a screw hole 62.

The branch hole 15 is closed by a lid 70. The lid 70 has a flat plate shape, and a protrusion 72 is formed on one end surface 71 thereof. Then, the lid 70 is attached to and detached from the mounting portion 60 with the bolt B screwed into the screw hole 62 with the one end surface 71 abutting against the mounting plane 61 and the protruding portion 72 fitted in the branch hole 15. Mounted as possible. An O-ring R for preventing gas leakage is provided between the lid 70 and the branch hole 15.
And packing P are attached.

FIG. 4 shows an example in which a new gas appliance is added by using the gas plug 1 having the above-described structure. The lid 70 is removed from the mounting portion 60 and the joint 80 is connected to the lid 7.
Similarly to the case 0, it is detachably attached to the attachment section 60. The joint 80 has a tapered female thread portion 81,
The tapered female screw portion 81 communicates with the branch hole 15.
Therefore, a gas pipe (not shown) is attached to the tapered female screw portion 81.
By screwing the gas pipes and connecting a new gas appliance to the gas pipe, the gas appliances can be added.

FIG. 5 shows another example in which a gas appliance is added using the gas stopper 1. A joint 90 is detachably attached to the mounting portion 60 in the same manner as the lid 70. I have. The joint 90 has a plug portion 91 of a quick joint at the tip end thereof, which is defined by Japanese Industrial Standards (JIS). When a socket (not shown) is connected to the plug portion 91, the valve element 93 and the sub-valve 94 provided in the gas passage 92 of the quick joint 90 are opened. Then, the gas in the inflow path 11 is supplied to a new gas appliance via the branch hole 15, the gas passage 92, the socket, and the gas pipe (not shown) connected to the socket.

As described above, the gas stopper 1 has the inflow path 11
Is provided with the mounting hole 60 to which the joints 80 and 90 are detachably attached, so that the gas appliances can be easily added by attaching the joints 80 and 90 to the mounting portion. it can. Moreover, there is no need to remove or reattach the gas pipe on the main plug side from the gas plug 1. Therefore, the labor required for the extension can be greatly reduced. In particular, when the joint 90 is used, it is only necessary to extrapolate the socket to the plug portion 91, so that the labor required for additional installation can be further reduced.

When it is not necessary to add a new gas appliance, since the branch hole 15 is closed by the lid 70, there is no possibility that gas leaks from the branch hole 15.
If gas leakage from the branch hole 15 is simply prevented,
The joint 90 provided with the valve element 92 and the sub-valve 93 may be attached to the gas plug 1 in advance, but in such a case, the price of the gas plug 1 rises because the joint 90 is expensive. In this regard, since the lid 70 is merely a flat plate, it is inexpensive, and the price of the gas stopper 1 can be kept low.

Further, since the mounting portion 60 is formed on the side of the main body 10 which is oriented in a direction perpendicular to the rotation axis of the plug 50, the joints 80 and 90 mounted on the mounting portion 60 allow the handle H to rotate. There is no hindrance to dynamic operation. Moreover,
The gas stopper 1 is often arranged along a wall surface and a floor surface. In such a case, the joints 80 and 90 can be easily attached.

It should be noted that the present invention is not limited to the above embodiment, but can be changed as appropriate. For example, in the above embodiment, the present invention is applied to the gas stopper 1 in which the inflow path 11 and the outflow path 12 are arranged in a straight line, but in the present invention, the inflow path 11 and the outflow path 12 are orthogonal. The present invention is also applicable to a gas stopper formed so as to perform the above operation. Further, in the above embodiment, one branch hole 15 and one mounting portion 60 are formed, but two or more branch holes 15 and two mounting portions may be formed. Further, although the joints 80 and 90 are fixed by the bolts B, a female screw portion may be formed in the opening outside the branch hole 15, and the joint may be screwed and fixed to the female screw portion.

As described above, according to the first aspect of the present invention, an effect that a new gas appliance can be easily added can be obtained. According to the second and third aspects of the present invention, a new gas appliance can be further easily added, and the joint attached to the mounting portion is prevented from obstructing the turning operation of the handle of the gas cock. The effect is obtained. According to the invention according to claim 4, it is possible to prevent the gas from leaking from the branch hole, and to obtain the effect of reducing the cost of the gas stopper. According to the invention according to claim 5, an effect is obtained that a new gas appliance can be more easily added.
