BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas plug suitable for use in installing a new gas appliance in addition to an existing gas appliance.

[0002]

2. Description of the Related Art In general, a gas tap communicates with an inlet port to which a gas pipe on the main cock side is connected, an outlet port to which a gas pipe on the gas equipment side is connected, and the inlet port and the outlet port. Gas passage, and a plug that opens and closes the gas passage,
It is installed near the gas equipment to be connected. For example, in a high-rise apartment house, when gas equipment is on a veranda or the like, it is installed on a wall facing the veranda.

[0003]

In the above multi-dwelling house, when gas equipment is added, a new gas equipment is often installed on the veranda adjacent to the existing gas equipment. In such a case, it is convenient if a new gas device can be connected to a gas tap to which an existing gas device is connected. However, conventional gas taps do not have a preliminary connection. Therefore, new gas equipment cannot be connected to the existing gas tap. For this reason, in the case of adding gas equipment, the number of gas taps must be installed for the number of gas equipment to be added, and gas piping work must also be performed for gas plugs. was there.

The present invention has been made to solve the above-mentioned problem. When a new gas device is added, both the new and old gas devices can be connected at the same time, so that piping work and the like become unnecessary. It is an object of the present invention to provide a gas stopper which can be used.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a gas stopper body in which a gas passage for communicating a gas inlet and a gas outlet is formed. In a gas plug provided in a plug main body and provided with a plug for opening and closing the gas passage and a handle for opening and closing the plug, a portion of the outer peripheral portion of the gas plug main body which is different from the handle in the circumferential direction. In the, provided a quick joint type connection portion having an outflow passage communicating with the gas passage located between the inflow portion and the plug body, in the outflow passage,
When the socket of the gas pipe is connected to the connection portion, the outflow path is opened, and when the socket is removed from the connection portion, a valve body that closes the outflow path is provided. The connecting portion is provided so as to be rotatable, and the distal end of the connecting portion is bent relative to the base end in a direction intersecting the rotation axis.

[0006]

When one gas appliance is used, the gas appliance is connected to the outlet. At this time, since the outflow path of the connection portion is closed by the valve, no gas flows out of the outflow path. When installing a new gas appliance in addition to the gas appliance connected to the outlet, the new gas appliance is connected to the connection unit. In this case, a quick joint type socket is attached to a gas pipe for connecting a new gas device. Then, when this socket is connected to the connection portion, the valve element opens the outflow passage. Therefore, gas is also supplied to the new gas equipment.

[0007] In the state where the gas equipment is connected to the outlet and the connection part, for example, when repairing the gas equipment connected to the outlet, the plug of the gas tap must be closed. Since it communicates with the gas passage upstream of the body, gas flows into the outflow passage even when the plug is closed. Therefore, the gas equipment connected to the connection part can be used independently irrespective of the open / close position of the plug.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 to 4 show a gas stopper according to the present invention. FIG. 1 is an enlarged sectional view taken along the line AA of FIG. 3, FIG. 2 is a longitudinal sectional view, FIG. Is an enlarged sectional view of a main part.

In the drawings, reference numeral 1 denotes a gas stopper main body. An inlet 1a is formed at one end of the gas stopper body 1,
An outlet 1b is formed at the other end. The inflow port 1a and the outflow port 1b are communicated with each other by a gas passage 1c formed inside the gas stopper main body 1.

A nut 2 is screwed into the inlet 1a, and an engaging member 3 is inserted therein. A nut (not shown) is formed by the nut 2 and the engaging member 3.
A flexible gas pipe (not shown) is connected to the inflow port 1a.

On the other hand, a joint 4 is rotatably and airtightly provided at the outlet 1b. And the gas equipment (not shown) is directly connected to the outlet part 1b by the joint 4,
Alternatively, they are connected via a gas pipe (not shown).

In a middle portion of the gas passage 1c, a through hole 5 is provided.
The plug 5 having a is rotatably arranged. Plug 5
Is for opening and closing the gas passage 1c. In the state shown in FIG. 1, the gas passage 1c is closed. When the stopper 5 is rotated by approximately 90 ° by the handle H from this state,
The upstream side (inlet 1a side) and the downstream side (outlet 1b) of the gas passage 1c communicate with each other through the through hole 5a, and the gas passage 1c is opened.

The connection structure of the gas pipes at the inlet 1a and the outlet 1b and the opening / closing structure of the gas passage 1c by the plug 2 are well known and are not related to the gist of the present invention. A detailed description thereof will be omitted.

The gas plug main body 1 has a projection 1d formed on an outer surface located between the inlet port 1a and the plug body 5. The protruding portion 1d is arranged at a position substantially 90 ° apart from the handle H in the circumferential direction of the gas plug main body 1, and is formed so as to protrude in a direction orthogonal to the rotation axis of the handle H. The protruding portion 1d is formed with a mounting hole 1e extending from the distal end surface to the gas passage 1c. A connection base (connection portion) 6 is rotatably attached to the mounting hole 1e.

As shown in FIG. 4, the connection base 6 has a tubular shape bent at a right angle at the center, and has a fitting portion 6a on the base end side and a direction orthogonal to the fitting portion 6a. And a cylindrical portion 6b extending to the end. The fitting portion 6a
The stop ring 7 is rotatably fitted in the mounting hole 1e.
Has been prevented by. O-rings 8 and 9 seal the space between the outer peripheral surface of the fitting portion 6a and the inner peripheral surface of the mounting tubular portion 6b. On the other hand, a plug portion 6c is formed on the outer peripheral surface of the distal end portion of the connection tube portion 6b. This plug part 6
c has the same shape as the plug of the quick coupling specified in Japanese Industrial Standard S-2120 or S-2135,
The socket attached to the gas pipe on the gas appliance side is connected. At the time of connection, the orientation of the plug portion 6c can be changed to an arbitrary direction of 360 ° by rotating the fitting portion 6a.

Here, the connection base 6 is arranged at a position which is distant from the handle H in the circumferential direction of the gas stopper main body 1, and is arranged in this manner for the following reason. If the connection base 6 is arranged at the same position in the circumferential direction of the handle H and the gas stopper main body 1, the connection base 6 is
Or when the handle H is rotated, the connection base H becomes an obstacle. In particular, when the connection base 6 is rotatable and its tip is bent, FIG.
As can be seen from FIG. 5, not only does the connection base 6 interfere, but when the plug portion 6c of the connection base 6 is turned toward the handle H, the handle H can hinder the connection of the socket to the plug portion 6c. Can not. The socket can be connected to the plug 6c only at the maximum.
It is only in the range of approximately 180 ° that c faces away from the handle H. Of course, if the connection base 6c is arranged away from the handle H in the axial direction of the gas stopper main body 1, such a problem does not occur.
The distance from the handle H increases the length of the gas plug main body 1 on the side of the inlet port 1a, which causes a problem that the gas plug main body 1 becomes large. In this regard, in the gas stopper, the connection base 6 is arranged in the circumferential direction of the gas stopper main body 1 with respect to the handle H, so that even if the connection base 6 is arranged close to the handle H, the connection base 6 is disposed. Does not interfere with the handle H or hinder the operation of the handle H. Therefore, the length of the gas plug main body 1 in the axial direction can be shortened, and the size of the gas plug main body 1 can be reduced accordingly. Moreover, even if the plug 6c is oriented in any direction of 360 °, the socket can be connected to the plug 6c without the handle H becoming an obstacle.

An outflow passage 6 d is formed inside the connection base 6. The outflow passage 6d is provided with an overflow prevention valve housing hole 6 extending from the end surface of the fitting portion 6a toward the connection cylinder portion 6b.
e, an opening / closing valve storage hole 6f penetrating the cylindrical portion 6b in the axial direction thereof, and a communication hole 6g for communicating the two storage holes 6e and 6f. The storage hole 6e is the mounting hole 1
Through e, it communicates with a gas passage 1c located between the inlet 1a and the plug 5. The rear end of the storage hole 6f is closed by the lid 10. A valve seat 6h having a tapered hole shape is formed on the inner peripheral surface of the distal end portion of the storage hole 6f.

The opening / closing valve 11 is housed in the housing hole 6f. The on-off valve 11 has a main valve (valve element) 11a and an auxiliary valve (valve element) 11b. The main valve 11a has a cylindrical shape, and its outer periphery is slidably and air-tightly fitted to the inner periphery of the storage hole 6f. The main valve 11a has a slit 11c extending in the axial direction. Then, a part of the ball 12 is fitted into the slit 11c and is prevented from rotating. A spring receiver 11d is fitted and fixed to the inner periphery of the main valve 11a, and the main valve 11a is held by a first spring 11e.
It is urged to the tip side via d.

When the main valve 11a is not used and the socket is not connected to the plug portion 6c, the outer peripheral surface of the main valve 11a has the communication hole 6c.
g, so as to close the outflow path 6d. On the other hand, when the socket is connected to the plug portion 6c, the main valve 11a is connected to the sub valve 11 by the rod R of the socket.
b to the rear end side, and moves to the position shown by the creation line in FIG. 4 to open the communication hole 6g, and thus the outflow path 6
Open d. The main valve 11a initially moves toward the rear end only against the urging force of the first spring 11e. However, the main valve 11a abuts on the second spring 11f during the movement, and thereafter the first and second springs 11f. Move against the urging force of the springs 11e and 11f.

The sub-valve 11b is for opening and closing the storage hole 6f by being seated and separated from the valve seat 6h, and for opening and closing the outflow passage 6d. The rear end of the sub-valve 11b is the tip of the main valve 11a. Part. Accordingly, the sub-valve 11b is pushed toward the distal end by the urging force of the first spring 11e, and thereby is seated on the valve seat 6h.

A spring 11g for urging the sub-valve 11b toward the distal end is provided between the sub-valve 11b and the spring receiver 11d. By the spring 11g, the auxiliary valve 11b is seated on the valve seat 6h regardless of the position of the main valve 11a when the socket is not connected to the plug portion 6c when not in use. That is, if the spring 11g is not installed, the main valve 11a is removed despite the socket being removed.
Is stopped in the open state for some reason,
Of the spring 11e does not act on the auxiliary valve 11b.
For this reason, the sub-valve 11b also remains open, and the outflow path 6
Gas flows out of d. In this regard, in this gas plug provided with the spring 11g, the auxiliary valve 11b is always seated on the valve seat 6h by the urging force of the spring 11g, and the outflow passage 6d is closed to prevent the outflow of gas. Note that the urging force of the spring 11g is set to be weaker than the urging force of the first spring 11e.

An overflow prevention valve 13 and a reset mechanism 14 are provided in the storage hole 6e. Incidentally, these are known ones (for example, Japanese Utility Model Laid-Open No. 2-77371).
JP-A-2-77367), the configuration will be briefly described.

The overflow prevention valve 13 includes a valve seat member 13a, a valve body 13b, a guide member 13c, and a spring 13d. The valve seat member 13a has a cylindrical shape,
It is screwed and fixed to the storage hole 6e. A valve seat 13e is formed on the inner peripheral surface of the valve seat member 11a, and a guide member 13c is fitted and fixed. The valve body 13b is supported by a guide member 13c so as to be movable in the axial direction of the storage hole 6e, and is urged by a spring 13d in a direction away from the valve seat 13e. In this configuration, when the flow rate of the gas flowing through the storage hole 6e (outflow path 6d) becomes larger than a predetermined flow rate, the valve body 13b moves against the urging force of the spring 13d due to the gas pressure, and is moved to the valve seat 13e. To sit down. This prevents an overflow condition.

On the other hand, the reset mechanism 14 is provided for removing the valve 13b from the valve seat 13e when the valve 13b bites into the valve seat 13e and cannot be separated.
And a spring 14b. The reset body 14a is slidably fitted in the storage hole 6e, and a projection 14c formed at the tip is slidably fitted in the communication hole 6g, and is attached to the storage hole 6f by a spring 14b. It is being rushed. Note that gaps (not shown) are formed between the outer peripheral surface of the reset body 14a and the inner peripheral surface of the storage hole 6e, and between the outer peripheral surface of the projection 14c and the inner peripheral surface of the communication hole 6g. Gas flows through each gap.

The reset mechanism 14 operates as follows.
That is, when the main valve 11a moves to a position where the communication hole 6g is opened, the tip of the projection 14c enters the storage hole 6f. From this state, the main valve 11a is switched to the first and second springs 1.
When the main valve 11a moves toward the distal end by the urging forces of 1e and 11f, the main valve 11a hits the projection 14c and the reset body 14a
Is moved toward the overflow prevention valve 13 against the urging force of the spring 14b. At this time, when the valve body 13b of the overflow prevention valve 13 is seated on the valve seat 13e, the reset body 14a abuts on the tip of the valve body 13b, and separates the valve body 13 from the valve seat 13e. Note that the valve body 13 separated from the valve seat 13e
b is returned to the original position by the spring 13d.

When one gas device is used in the gas plug having the above-described structure, the gas device or a gas pipe connected to the gas device is connected to the outlet port 1b by the joint 4. At this time, no gas pipe is connected to the connection base 6,
The outflow passage 6d is connected to the main valve 11a and the sub-valve 1 of the on-off valve 11.
Since it is closed by 1b, no gas flows out of the outflow passage 6d. Therefore, this gas stopper can be used in the same manner as a conventional gas stopper having only one portion to which a gas device is to be connected.

When installing a new gas appliance in addition to the gas appliance connected to the outlet 1b, a socket of a quick joint is attached to the gas pipe of the gas appliance, and the socket is connected to the plug 6c of the connection base 6. Connect to At this time, since the base end of the connection base 6 is rotatable, the direction of the plug portion 6c can be changed to any direction of 360 °. For example, when a new gas appliance is installed on the inlet 1a side, the plug 6c is directed toward the inlet 1a, and when installed on the outlet 1b, the plug 6c is connected to the outlet. It can face to the part 1b side. Therefore, in any case, the socket can be easily connected to the plug portion 6c. In particular, new gas appliances should be
When the socket is arranged on the side b, the connection base 6 is arranged at a distance from the handle H in the circumferential direction of the gas stopper main body 1, so that when the socket is connected to the plug portion 6c, the handle H hinders the connection. And the gas pipe does not hang on the handle H. Therefore, the socket can be more easily connected to the plug portion 6c. When the socket is connected to the plug portion 6c, the main valve 11a and the sub-valve 11b of the on-off valve 11 are opened by the rod R of the socket. Therefore, gas is supplied to the new gas appliance.

In a state where gas equipment is connected to the outlet 1b and the connection base 6, respectively, the outlet 1b
When removing the gas equipment connected to the device for repair or the like, the plug 5 of the gas plug is closed. At this time, since the outflow passage 6d of the connection base 6 communicates with the gas passage on the upstream side of the plug 5, gas flows into the outflow passage 6d even if the plug 5 is closed. Therefore, the new gas equipment connected to the connection base 6 can be used independently of the open / close position of the plug 5.

The present invention is not limited to the above-described embodiment, but can be appropriately changed without departing from the scope of the invention. For example, in the above embodiment,
The flexible gas pipe is connected to the inlet port 1a by the nut 2 and the engaging member 3, but a taper screw or the like is formed on the inner peripheral surface of the inlet port 1a so that the gas pipe is screwed and fixed. You may. This is the same for the outlet 1b.

[0030]

Further, in the above-described embodiment, two valves, the main valve 11a and the sub-valve 11b, are provided as valve bodies for opening and closing the outflow passage 6d, but only one of them is provided. You may do so.

[0032]

As described above, according to the gas plug of the present invention, a quick-coupling-type connecting portion having an outflow passage communicating with the gas passage is provided on the gas plug body upstream of the plug. At the same time, the connecting portion is provided with a valve body that opens and closes the outflow path according to the attachment and detachment of the socket to and from the connecting portion. Therefore, when only one gas appliance is used, it is similar to a conventional gas stopper. Can be used. Further, by connecting a gas pipe to the connection portion, a new gas appliance can be used in addition to the existing gas appliance. Therefore, if the gas plug of the present invention is installed in place of the conventional gas plug, gas appliances can be added without performing piping work or the like. In addition, since the outflow passage communicates with the gas passage upstream of the plug, a new gas appliance connected to the connection portion can be used independently of the opening and closing of the plug. In addition, since the connecting portion is provided rotatably on the gas stopper main body and separated from the handle in the circumferential direction of the gas plug main body, the gas plug main body can be downsized, and the connecting portion can be formed at 360 °. It can be oriented in any direction, and even when oriented in either direction, the effect is obtained that the socket can be connected to the connection portion without the handle becoming an obstacle.
