[Prior Art] Conventionally, when connecting a gas pipe installed in the interior space of a wall to a gas appliance installed on the indoor side of the wall, the connection was performed as shown in Fig. 4. Ta. That is, an air venting joint C is connected to the gas pipe B installed in the internal space of the wall A, and the air venting joint C is connected to the gas pipe B for removing the air present in the pipe after the piping is completed, and the flow direction of the gas is connected to the joint C in a direction perpendicular to the wall surface. A right-angled elbow D that changes the direction along the wall is connected, and an opening/closing handle E is connected to this elbow D. And gas appliances such as instant water heaters F to Kotsuku E.
This is to connect the gas pipe G.

[Problem to be solved by the invention] Since the joint D, the elbow E, and the joint F are connected in sequence between the gas pipe B and the gas appliance F, the gas pipe B and the gas appliance F are There was a problem that it took a long time to connect. Furthermore, since there are many parts for connection, there is a problem of increased costs.

[Purpose of the invention] This invention was made in consideration of the above-mentioned circumstances, and it is possible to quickly connect gas pipes and gas appliances installed in an internal space such as a wall or floor, and it also uses connecting parts. It is an object of the present invention to provide a gas tank that can reduce the cost by reducing the number of points.

[Structure of the device] In order to achieve the above object, this device includes an inflow path and an outflow path that extend in directions crossing each other, and a plug insertion portion between the inflow path and the outflow path. The body of the kotuku formed by
A stopper is rotatably inserted into the stopper insertion portion of the main body, and one end is opened on the outer surface facing the rotation axis direction, and one end of the stopper is open to the outside of the stopper, and one end of the stopper is open to the outside of the stopper, and one end of the stopper is open to the outside facing the rotation axis direction. The plug is connected to one end, and the other end is opened on an outer surface facing in a direction intersecting the rotational axis, and the inflow channel and the inflow channel can be in a communicating state and a blocked state by rotation of the plug body. a gas passage which can be switched to the gas passage is formed, and an outflow hole is formed in the plug body, one end opening to the wall surface of the gas passage and the other end opening to the outer surface facing in a direction intersecting the rotation axis,
One end of the cock body is opened to the wall surface of the plug insertion part, and the other end is opened to the outside surface, and the one end opening in the wall surface of the plug insertion part is in a state where a gas passage is in communication with the rotation of the plug body. An air vent hole is formed that communicates with the outflow hole when the gas passage is in the closed state and is blocked from the outflow hole when the gas passage is in the blocked state. It is characterized by a removably attached opening/closing valve.

[Embodiment] An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 to 3, the reference numeral 1 in the drawings indicates the main body of the kettle. Inside this Kotuku body 1,
An inflow path 11 and an outflow path 12 are formed that extend in directions perpendicular to each other. The inflow passage 11 opens on the outer surface of the pot body 1 facing downward in FIG. 1, and extends upward from the opening. On the other hand, the outflow passage 12 opens on the outer surface of the pot body 1 facing right in FIG. 1, and extends from the opening toward the left. A shaft plug is placed between the inflow path 11 and the outflow path 12.
Plug insertion hole (plug insertion part) 13 aligned with the axis of 1
is formed. The plug insertion hole 13 has a tapered hole shape whose diameter gradually becomes larger as the distance from the plug insertion hole 13 increases, and the inner end of the inflow passage 11 opens at the bottom, and the outflow flows from the peripheral wall surface. The inner end of channel 12 is open.

Incidentally, each opening of the inflow passage 11 and the outflow passage 12 is formed with a tapered internal pipe thread portion 11a, 12a, respectively, for connecting a gas pipe. Further, a flange 14 is formed at the end of the pot body 1 where the inflow passage 11 is formed.

A correspondingly tapered plug body 2 is rotatably inserted into the plug insertion hole 13. A gas passage 21 is formed inside this stopper. One end of the gas passage 21 opens to the small-diameter end surface of the plug body 2, and the other end opens to the outer circumferential surface of the plug body 2. Therefore, the gas passage 21 is always in communication with the inflow path 11, but is switched between the communication state and the cutoff state with the rotation of the stopper 2 with respect to the outflow path 12. It is now possible to open and close the gas kottok. Note that the stopper 2 is rotated by a handle 3, and the rotation angle from the fully open state to the fully closed state is approximately 90°.

In addition, this gas tank is configured as follows in order to vent air from inside the piping. That is, the main body 1 located on the axis of the outflow passage 12
A protrusion 15 is formed on the outer surface of. This protruding part 15 is for inserting a gas pipe such as a rubber pipe connected to a test instrument such as a gas pressure tester into its outer periphery. An air vent hole 16 is formed to coincide with the air vent hole 16. The inner end of the air vent hole 16 opens into the wall surface of the plug insertion hole 13. Also,
A shutoff plug 4 is screwed and fixed to the outer end of the air vent hole 16. This opening/closing stopper 4 is for opening and closing the air vent hole 16 by attaching and detaching the opening/closing stopper 4, and a gasket 5 and an O-ring 6 are installed between the opening/closing stopper 4 and the cock body 1, respectively.

On the other hand, the plug body 2 is formed with an outflow hole 22 whose one end opens to the outer peripheral surface and the other end opens to the wall surface of the gas passage 21 . As shown in FIG. 2, the outflow hole 22 is positioned so as to communicate with the air vent hole 16 when fully opened, and to be blocked from the air vent hole 16 when fully closed.

However, in the gas tank with the above configuration,
Since the axes of the inflow passage 11 and the outflow passage 12 are perpendicular to each other, the gas cock itself functions as an elbow for changing the direction of gas flow. Moreover,
If the air vent hole 16 and the outflow hole 22 are opened and communicated with each other, air can be vented from the air vent hole 16. In other words, this gas tank also has the function of an air vent joint. Therefore, according to this gas tank, the elbow and air vent joint in the prior art described above are unnecessary.
The work time required for piping can be reduced accordingly. In addition, although the gas socket itself is slightly more expensive than the conventional one that simply switches between opening and closing, the cost is significantly reduced compared to using a switching gas socket, an elbow, and an air vent joint. be able to.

Furthermore, when air is removed, the safety of the work can be ensured. That is, when venting air, it is necessary to open the gas cock, but if the stopcock 4 is opened and removed from the air vent hole 16, gas and air will suddenly blow out from the air vent hole 16, which is dangerous. . In this respect, in this gas tank, if the gas tank is kept in the closed state, gas will not blow out even if the stopcock 4 is removed from the air vent hole 16. Therefore, work safety can be ensured.

Note that after removing the stopcock 4 and confirming that there is no fire, air can be vented by opening the gas tank.

In addition, in the above embodiment, the plug insertion hole 13
The axis of the inflow path 11 is made to coincide with the axis of the inflow path 11, but
It may be made to coincide with the axis of the outflow path 12. In that case, the air vent hole 16 should be
It will be formed at a position opposite to.

Further, although the plug body 2 is formed into a tapered shape, it may be formed into a cylindrical shape or a spherical shape. In that case, it goes without saying that the plug insertion hole 13 should also be formed into a straight hole shape or a spherical shape corresponding to the plug body 2.

[Effects of the invention] As explained above, according to the gas tank of this invention, since the inflow channel and the outflow channel are formed to extend in directions that intersect with each other, the gas flow can be changed by the gas tank itself. can. Moreover,
By forming the outflow hole and the air vent hole, air can be vented from them. Therefore, the elbows and air vent joints that were conventionally required are no longer necessary, and the connection work time can be shortened by the time required to connect them. Furthermore, whereas conventionally three parts were required: a gas socket for opening/closing, an elbow, and an air vent joint, one gas socket is sufficient, so the cost required for connection can be significantly reduced. Furthermore, since the air vent hole and the outflow hole are blocked when the gas tank is in the closed state, the safety of the air venting operation can be ensured.
