Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas meter having a gas meter protective cover that also serves as a pipe holder.

[0002]

[Prior art]

 Generally, a gas meter has an input port and an output port.The input port is connected to the input pipe from the main pipe through the main plug, and the output port is connected to the output pipe, which is used for gas bath, gas stove, and other gas. The equipment is supplied with gas. This type of gas meter is usually exposed outdoors.

Further, the input pipe and the output pipe of the gas meter are made of metal (carbon steel or the like). On the other hand, since there is a potential difference depending on the position of each pipe, an electric circuit is generated through the input / output pipe. Since there is a risk that current will flow, corrode the pipe, and cause gas leakage, conventionally, for example, an insulating member for electrically insulating the input side and the output side was provided in the proper place of the input pipe. Some are equipped with a pipe joint.

[0004]

[Problems to be solved by the device]

 In the conventional gas meter described above, the meter body is exposed to the outside, so rain drops and snow directly hit it, and the temperature inside the meter changes due to direct sunlight, which causes malfunctions and deterioration of internal electronic components. There is a problem in that the life of the meter is shortened due to such problems as being caused, and the position of the input / output pipe is changed due to a fallen object, etc., and the meter is damaged.

Further, the gas meter has an input port and an output port on the upper side, and the gas meter is usually in a mode of being suspended from the input pipe and the output pipe. Since the gas meter has a comparatively heavy weight, a load is applied to the input / output section, or external force is applied to the input / output pipe, which damages the meter over a long period of use, which may cause gas leakage depending on the type of damage. was there.

The present invention has been made in view of the above problems, and aims at providing a gas meter having a long life by protecting the meter body from raindrops, snowfall, falling objects, sunlight, and the like. There is.

[0007]

[Means and Actions for Solving the Problems]

 The gas meter of the present invention has a pair of holes for penetrating the input pipe and the output pipe, and is equipped with a gas meter protective cover that covers the upper part of the gas meter main body. The input pipe and the output pipe are held at a fixed distance by penetrating the output pipe through the hole.

In this gas meter, since the gas meter protective cover is provided above the meter body, raindrops, snowfall, and falling objects can be prevented from hitting the meter body directly, and direct sunlight is also reduced. Moreover, since the input pipe and the output pipe are held at a certain distance by the hole of the gas meter protective cover, the possibility that the meter is damaged by external force or load is reduced.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to examples. FIG. 1 is a front view of a gas meter showing an embodiment of the present invention, and FIG. 2 is a side view of the gas meter of the embodiment. In the embodiment, an input port 2 and an output port 3 for gas are provided on the upper part of the gas meter main body 1, an input pipe 4 is connected to the input port 2 and an output pipe 5 is connected to the output port 3. Has been done. Each of the input pipe 4 and the output pipe 5 is provided with an elbow 6, a pipe joint 7 and a cap nut 8 at the tip thereof, and is connected to the gas meter body 1 by these. Further, the input pipe 4 and the output pipe 5 are held at a constant distance from each other by a holder 9 that also serves as a gas meter protective cover of the gas meter body 1.

Next, the structure of the holder / gas meter protective cover 9 and the method of mounting the same will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, the gas meter protection cover 9 has a substantially rectangular shape in a plan view, is formed of a metal plate, a resin plate, or the like, and has an area large enough to cover the upper portion of the gas meter 1. A pair of holes 11 for penetrating the input pipe 4 and the output pipe 5 are provided, and cylindrical bobbin-shaped insulating rubbers 13 having upper and lower flanges 12a are fitted in the holes 11, respectively. .

When the gas meter protective cover 9 also serving as a pipe holder is attached to the output pipe 5, the cap nut 8, the hexagon nut 13, and the hole 11 of the gas meter protective cover 9 are first attached to the output pipe 5 from below the elbow 6. Fasten the threaded pipe joint 7 with screws and fix the gas meter protective cover 9 to the lower end of the elbow 6 with the hexagon nut 13. After that, the inner cylinder of the pipe joint 7 is hexagonal. Rotate 7 to connect with elbow 6. After that, the cap nut 8 is rotated and fastened to the output port 3 of the gas meter body 1. The case of fixing the gas meter protective cover 9 to the input pipe 4 is the same as the case of fixing to the output pipe 5 described above, and therefore the description thereof is omitted. FIG. 4 shows a side view of the gas meter protective cover 9 shown in FIG.

In this embodiment, since the gas meter protection cover 9, the elbow 6 and the pipe joint 7 are separated by the insulating rubber material (rubber, resin, etc.) 12, the input pipe 4 side and the output pipe 5 side are electrically connected. Electrically isolated. In the above-mentioned embodiment, the inner cylinder of the pipe joint 7 is hexagonal, but of course, it may be a conventional circular one.

[Effect of device]

 According to this invention, since the gas meter protective cover is provided above the gas meter main body, the meter can be protected from raindrops, snowfall, and falling objects, and direct sunlight can be reduced, so that the temperature of the meter rises. It is possible to prevent malfunction and deterioration of electronic parts, deformation of interlocking parts, and aging due to. Moreover, since the input / output pipe is held at a constant distance by the hole of the gas meter protective cover, it is possible to prevent damage to the gas meter body due to external force, load subsidence, or the like. Further, even if the gas meter protective cover is a metal plate, holding the input / output pipe through the insulating member provides electrical insulation between the input and output, and prevents corrosion of the metal gas pipe due to potential difference. Therefore, a gas leak accident can be prevented.
