DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas plug attached to a gas conduit or a gas appliance for use.

[0002]

2. Description of the Related Art Conventional gas stoppers include those having a straight gas passage formed in a gas stopper body and those having a right-angled (L-shaped) gas passage formed. When the gas flow path is straight, it is attached to the gas plug body in a direction perpendicular to the gas flow path, and when the gas flow path is right, it is installed on one of the extension lines that intersect at right angles.

FIG. 4 shows an example of an L-shaped gas stopper (gas stopper) in which gas passages are formed at right angles, in which 20 is a gas stopper main body, 21 is a gas passage formed at a right angle, and 22 is a gas passage. Input side connection port, 23 is output side connection port, 24 is a closure incorporated on an extension of the input side connection port 22, 25 is a handle, 26 is a gas conduit, 27 is an elbow, 28 is a straight pipe, and 29 is a gas meter. Three
Reference numeral 0 is a connector (cap nut) that connects the inlet side connection port 22 of the gas stopper 1 and the inlet side base 30 of the gas meter 29.

As described above, the conventional L
In the case of a type gas plug, since the handle 25 (closer 24) is attached to one extension line of the gas flow path 21 that intersects at a right angle, when it is attached to a pipe, it usually faces the horizontal direction or the vertical direction. Will end up. Therefore, there is a drawback in that it is difficult to operate the handle 25 depending on the position of the gas plug.

Conventionally, in order to eliminate such drawbacks,
For example, if you want to turn the handle 25 at an angle of 45 °,
The gas conduit itself is routed so that the handle 25 is inclined at 45 °. However, if such a method is adopted, there is a drawback that a large piping space is required, the apparatus becomes large in size, and the piping material is increased to increase the cost.

[0006]

DISCLOSURE OF THE INVENTION The object of the present invention is to propose a gas stopper constructed so that the handle can be oriented at an angle of 45 ° without increasing the piping and increasing the amount of piping material. , Its structure is as follows. 1. A gas flow path connecting the inlet side connection port and the outlet side connection port formed in the gas stopper body is formed in an arc shape, and an on-off valve is installed in the middle of this, and a handle for operating this on-off valve is installed in the middle of the gas stopper body. There is a gas plug attached outside the arc. 2. 2. The gas plug according to 1 above, wherein the gas flow path is curved by a polygon. 3. The above-mentioned 1 in which the arc of the gas flow path is 30 ° to 120 °
Alternatively, the gas plug according to item 2. 4. The gas flow path is 90
By connecting the gas plug formed at 90 ° using a bend pipe or elbow at 90 °, the outlet side connection port of the gas stopper is formed downward, and the downward side formed outlet side connection port of the gas meter 3. The gas plug according to 1 or 2 above, which is formed by connecting bases directly or using a connecting pipe. 5. 5. The gas plug according to 1 or 2 or 3 or 4, wherein the opening / closing valve is a closure having a tapered sealing surface, a ball valve, or a butterfly valve.

[0007]

When the gas pipe body is attached to a portion where the gas pipe is bent at a right angle, for example, the handle is tilted upward by 45 °. As a result, it is very easy to operate in some places.

[0008]

1 is a front view of a gas plug according to the present invention, FIG.
1 is a cross-sectional view taken along the line AA ′, 1 is a gas plug body, 2 is a 90 ° arc gas passage formed in the gas plug body 1, 3
Is an inlet connection port of the gas flow path 4, 4 is an outlet connection port, 5 is a closure incorporated in the center of the gas plug body 1, and 6 is a handle for opening and closing the closure 5. Although the gas flow path 2 of the above-mentioned embodiment is formed in a circular arc shape by concentric circles, as shown by a chain line P in FIG. 2, a straight line is formed between the inlet side connection port 3 and the outlet side connection port 4. It may be a polygonal arc to connect.

FIG. 3 shows an example of use in which the above-mentioned gas plug is installed as a main plug on the inlet side of a gas meter. 7 is a gas conduit which is vertically raised, and 8 is connected to the tip of this gas conduit 7. ° Bending pipe with bending. Gas stopper body 1
The inlet side connection port 3 of the bend tube 8 is a horizontally changed tip 8 of the bend pipe 8.
The position of the handle 6 is changed to 45 by being connected to a.
° Upward. Reference numeral 9 is a straight pipe connected to the outlet side connection port 4 of the gas stopper body 1. A cap nut 10 is attached to a lower end 9a of the straight pipe 9, and a cap 12 on the inlet side of the gas meter 11 is It is connected to the straight pipe 9 by a cap nut 10.

In the above embodiment, the gas plug has a structure in which the gas passage 2 is shut off by the closing member 5 having a tapered surface. However, instead of the closing member 5, a ball valve or a butterfly valve may be used. May be. Further, the arc of the gas flow path 2 can be arbitrarily formed within the range of 30 ° to 120 ° depending on the use of the gas plug.

[0011]

As described above, the gas plug according to the present invention has the following effect because the gas passage is formed in an arc shape and the handle is located outside the arc. a. Since the gas plug itself is curved, the handle can be turned upward, for example, by 45 ° without having to circulate the pipe. Therefore, when it is desired to turn the handle upward by 45 °, the piping space is minimal, and the handle can be installed in a narrow place or incorporated in a small gas appliance for use. b. The handle can be mounted not only at an angle of 45 ° diagonally upward, but also at an angle of 45 ° diagonally downward. c. When the handle is attached at an angle of 45 °, for example, no special piping material is required, so that no special piping cost is required. In particular, when the inlet side and outlet side connection ports of the gas plug are oriented in a right angle direction, the gas plug can also serve as a bend pipe or an elbow. As a result, when installing the gas meter, by using the gas stopper as the main stopper and the elbow or the bend pipe, one elbow or the bend pipe becomes unnecessary.
