DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to the installation how general household gas meter.

[0002]

2. Description of the Related Art FIG. 4 shows an installation state of a conventional gas meter.
Reference numeral 3 denotes a meter outlet pipe, 4 denotes a gas tap (main plug) mounted in the middle of the meter inlet pipe 2, 5 denotes an inlet-side horizontal elbow, 6 denotes an inlet-side downward elbow, 7 denotes an outlet-side horizontal elbow, and 8 denotes an outlet side. Downward elbow, 9 is the union, 10 is the union,
Reference numeral 11 denotes an inlet base, and 12 denotes an outlet base.

In this conventional example, when the gas meter 1 is installed, the gas plug 4 is rotated and screwed to the meter inlet pipe 2 raised from the ground as shown in FIG. A horizontal elbow 5.7 is connected to the upper end of the meter outlet pipe 3 and a downward elbow 6.8 is further connected to the elbow 5.7 using a connecting pipe 13.14. By connecting the inlet union 9 and the outlet union 10 to the inlet cap 11 and the outlet cap 12, the gas meter 1 is attached to the meter inlet pipe 2 and the outlet pipe 3 so as to be hung.

[0004]

Therefore, when the conventional gas meter 1 is installed, there are the following disadvantages. a. 5 As is clear from, the gas plug 4 meter pipe 2
When the gas stopper 4 is mounted, it is necessary to rotate the gas stopper 4. For this reason, since the gas meter 1 is usually installed along the outer wall a of the house, the positions of the meter inlet pipe 2 and the meter outlet pipe 3 are as follows.
It is necessary to provide a space (interval) sufficient to rotate the gas stopper 4 between the outer wall a and the gas meter 1, and the position of the gas meter 1 projects forward away from the outer wall a.

B. Since the gas meter 1 protrudes from the outer wall a, an object is easily hit and the gas meter 1 is easily damaged. c. When the gas meter 1 protrudes from the outer wall a, the appearance is poor. d. The position of the gas meter 1 is increased by the amount of attaching the gas stopper 4 to the meter inlet pipe 2 side.

E. It takes time and effort to work because the gas stopper 4 is attached to the meter inlet tube 2. f. When installing the gas meter 1, use a horizontal elbow 5
The cost is high because a total of four elbows, 7 and downward elbows 6.8, are used. g. As a means for solving the drawback described in the above f, a method of using a gas stopper combined with an elbow equipped with an upward handle at the upper end of the meter inlet pipe 2 (Japanese Patent Application No. 5-19320).
No. 3), but also in this method, it is necessary to rotate the gas plug in order to attach it, and therefore, a space for a rotating space is required between the gas stopper and the outer wall. In addition to the drawbacks described above, since the handle is upward, if there is, for example, a bay window above the gas meter, the handle is difficult to rotate, which is inconvenient in an emergency. An object of the present invention is to solve the above-mentioned problems a to g.

[0007]

Means for Solving the Problems To achieve the above object,
Therefore, in the present invention as set forth in claim 1, when installing the gas meter, an elbow or a vent pipe is attached to the upper ends of the meter inlet pipe and the meter outlet pipe in a horizontal direction, and then the elbow or the vent pipe on the meter inlet pipe side is attached to the gas inlet. , it is attached to the opening and closing handle on the front, the forming a connections inlet for meter pipe side of the elbow or bent pipe rearward, fitted with a gas valve forming a connection outlet downward, further
The further mounting an elbow or bent-pipe down to the meter output pipe side of the elbow or bent pipe, connect the input side cap moth <br/> Sumeta thereon to connect the outlet of the gas valve,
The exit side base is obtained so as to connect to the meter output pipe side of the elbow or bent pipe.

[0008]

[Action] gas enters into the gas meter from the meter pipe via the gas valve for the main valve which also serves as a horizontal orientation elbow or bent pipe and a downward elbow or bent pipe, horizontally oriented elbow from the weighing after downward elbow or bent pipe or It passes through the vent pipe through the meter outlet pipe and through the indoor pipe to the gas appliance. Gas valve for the main valve, by opening and closing operation by gripping the handle from the front side, can or stopping flow of gas, which is a function of the known <br/> original plugs.

[0009]

Detailing the installation how the gas meter according to the present invention on the basis of EXAMPLES 1 to 3. FIG. 1 is a perspective view of a state where a gas meter 1 is installed, 2 is a meter inlet pipe, 3 is a meter outlet pipe, 5 and 7 are horizontal elbows, 8 is a downward elbow,
10 is an outlet union, 11 is an inlet cap, 12 is an outlet cap, and 13 and 14 are connection pipes.

Reference numeral 15 denotes a gas stopper for the main stopper which also serves as a downward elbow on the entrance side. The detailed structure of the gas stopper 15 is shown in FIG.
It will be described based on. 15a is a gas stopper body, 16 is a connection inlet provided behind the gas stopper body 15a, and 17 is a gas inlet.
In the plug body 15a, a connection outlet provided downward, and the connection outlet 17 and the connection inlet 16 are communicated by an inverted L-shaped gas flow path 18.

Reference numeral 19 denotes a plug (closer) which is incorporated horizontally with respect to the gas flow path 18, and an L-shaped opening / closing flow path 20 is formed in the plug 19. 21 is the stopper 19
The handle 21 is attached to the front side of the gas stopper body 15a.

An inlet union 22 is attached to the connection outlet 17 so as to be able to escape upward. The inlet union 22 connects the gas stopper 15 to the inlet cap 11 of the gas meter 1. I have. Gas stopper 1
Reference numeral 5 is attached to the horizontal elbow 5 by using a connection pipe 13, serves also as a downward elbow, and can be opened and closed using a handle 21 from the front side.

[0013]

As described above, according to the present invention, instead of the downward elbow or vent pipe on the inlet side, a gas plug is used by using a main stopper gas stopper which also serves as the downward elbow or vent pipe.
The following effects are achieved by attaching the data.

A. Gas tap is not installed in the middle of the meter inlet tube. As a result, the rotating space when the gas meter is mounted is not required between the outer wall and the meter, so that the meter inlet pipe and the outlet pipe can be brought as close as possible to the outer wall. b. Due to the effect of a, the projection of the gas meter is reduced, so that the chance of hitting and damaging the object is halved. c. The appearance is better because there is less protrusion.

D. Because there is no gas stopper in the middle of the meter inlet,
The position of the gas meter can be kept low. e. Since the gas stopper also serves as a downward elbow or a vent pipe on the entrance side, the labor and time required for mounting one component can be saved, and the construction cost can be reduced. f. Because the handle is facing the front, operability is good,
Even if there is an obstacle such as a bay window above, it can be closed immediately in an emergency or the like.
