Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure for a water meter casing to prevent freezing and destruction of the water meter.

[Conventional technology]

Some conventional cold-resistant water meter cases have insulation material on the back side of the lid and side walls, but if cold air enters through the gap in the lid or stays at low temperatures for a long period of time, it may leak through the insulation material. The heat inside the case will be absorbed and the temperature inside the case will drop below 0℃. Also, to prevent this,
Some have a heat insulating board that divides the inside of the case into a top and bottom to prevent cold air from entering from above, and some have a peephole in the heat insulating board and an inner cover.These have excellent heat retention effects, but they are difficult to read when reading the meter. There is a problem in that the heat insulating board and the inner cover must be removed one by one during the process, which is time-consuming.

[Problem that the invention attempts to solve]

In view of the above-mentioned problems, the present invention attempts to make it possible to easily read the meter without removing the heat insulating board, even though the meter is partitioned into upper and lower parts by a heat insulating board.

[Means for solving problems]

The present invention includes a water meter housing that houses a water meter, a heat insulating plate that vertically partitions this housing, and a long hole formed in the heat insulating plate facing above the water meter.
The casing consists of a peep pipe that is vertically and slidably inserted into the elongated hole, and a support plate that is movably placed on the heat insulating plate, into which the peep pipe is closely fitted and covers the elongated hole. The inside of the body is partitioned vertically by a heat insulating board, and the elongated holes in the heat insulating board, except for the peep pipe, are closed by support plates to prevent cold air from entering through the gap in the lid plate from entering the water meter side below the heat insulating board. In addition, the viewing pipe inserted vertically into the long hole of the insulation board can be adjusted in the long hole so that it is positioned directly above the water meter so that the top surface of the water meter can be peered into. This eliminates the need to remove the heat insulating plates one by one when reading the meter.

[Effect]

This invention divides the inside of the water meter housing into an upper and lower part with a heat insulating board to insulate the lower chamber where the water meter is housed from the outside air, and moves the sight pipe inside the long hole of the heat insulating board directly above the water meter. The support plate supports the sight pipe and closes the gap between the long hole and the sight pipe to prevent outside air and dirt from entering the lower chamber partitioned by the heat insulating board. It is.

〔Example〕

Embodiments of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a water meter housing, which is composed of a surrounding frame 3 with a heat insulating material 2 interposed therebetween, a lid plate 5 lined with a heat insulating material 4, and a bottom plate 6.

The housing 1 is divided into upper and lower parts by a heat insulating plate 7.
The water meter 8 is housed in the lower chamber partitioned by the water meter 8, and the water pipes 9, 9 of the water meter 8 are connected to the water pipe through holes 10, 10 of the surrounding frame 3.
It is derived from Further, a stop valve 11 is provided in the middle of the water pipe 9 approaching the water meter 8.

A long hole 12 is formed at a position above the water meter 8 on the heat insulating plate 7 so that the scale plate on the top surface of the water meter can be seen through, the long diameter direction of which is parallel to the axial direction of the water tube 9. A transparent sight pipe 13 is slidably inserted vertically into the elongated hole 12. The sight pipe 13 is closely fitted and supported by a supporting plate 14 movably placed on the heat insulating plate 7 covering the elongated hole 12, and its lower end is opened close to the scale plate of the water meter 8. The top end is placed close to the lid plate 5 of the housing 1, and two transparent lids 15, 1 made of acrylic resin plates are placed near the top end.
5 are glued and fixed vertically at intervals, and the space 16 is fixed.
In some cases, the pressure may be reduced.

Next, the operation of this embodiment will be explained.

It is partitioned into an upper and lower part by a heat insulating plate 7 and further has a long hole 12.
Since the gap with the peek pipe 13 is covered with the support plate 14, the water meter 8 housed in the lower chamber of the casing 1 partitioned by the heat insulating plate 7 can be inserted into the gap between the casing 1 and the cover plate 5. This prevents the cold air from entering from the outside and prevents the connection.

When reading the meter of the water meter 8, the transparent lid 15,
The scale plate of the water meter 8 located below can be read through the pipe 15, and since the sight pipe 13 is transparent, the surrounding light is not blocked. It doesn't make it darker. Furthermore, when the transparent cover 15 above the peep pipe 13 comes into contact with cold air on the ground, the insulating effect of the space 16 prevents the transparent cover 15 from fogging up due to the temperature difference between the outside air and the inside of the peep pipe 13 . is transparent lid 1
5, the cold air that has entered the upper chamber of the housing 1 is prevented from entering the peek pipe 13. Furthermore, even if dirt particles or other debris get into the housing 1 when the cover plate 5 is opened or closed, the gap between the elongated hole 12 opened in the heat insulating plate 7 and the peep pipe 13 is covered with the support plate 14. There is no possibility of water falling from the hole 12 onto the water meter 8. Also peep pipe 13
By bringing the upper end closer to the lid plate 5 and the lower end closer to the scale plate of the water meter 8, it is possible to prevent dust and the like from falling onto the transparent lid 15 and the scale plate.

Furthermore, when installing the water meter 8, leave a space between the water pipes 9, 9 at the position where the water meter 8 and the water stop valve 11 are inserted, and hold the housing 1 with a retaining material. Then, the water meter 8 and water stop valve 11 are inserted between the water pipes 9 and 9 to connect them. In this case, the position of the water meter 8 may move slightly to the left or right in the figure in the axial direction of the faucet 9, so move the sight pipe 13 in the long hole 12 to match the position of the water meter 8. The support plate 14 is slid on the heat insulating plate 7. Furthermore, since the axial direction of the water pipe 9 and the axial direction of the long diameter side of the long hole 12 can be aligned on the short diameter side of the long hole 12 when installing the housing 1, it is necessary to move the sight pipe 13 on the short diameter side. There isn't.

Further, in the above embodiment, the heat insulating plate 7 and the support plate 14
Although only one stage is provided, if the casing 1 is deep, two or more stages may be provided.

[Effect of idea]

According to the present invention, there is provided a water meter housing that houses a water meter, a heat insulating plate that vertically partitions this housing, and a long hole formed in the heat insulating plate facing above the water meter. , consisting of a peep pipe that is vertically and slidably inserted into the elongated hole, and a support plate that is movably placed on the heat insulating plate, into which the peep pipe is closely fitted and covers the elongated hole, The water meter housing has a heat insulating plate that separates the lid plate side at the top end from the side where the water meter is stored, preventing cold air from entering the water meter side through the gap between the housing and the lid. This can prevent the water meter from freezing. In addition, a long hole was formed in the heat insulating plate facing above the water meter, and a peep pipe was inserted upright into this long hole, so the scale plate of the water meter could be peered through the peep pipe. This saves you the trouble of removing the insulation board one by one. Furthermore, the sight pipe is slidably inserted into the elongated hole and is supported by a support plate placed on the heat insulating plate, so it can be slid inside the elongated hole to align the scale plate of the water meter. The support plate supports the sight pipe and closes the gap between the sight pipe and the elongated hole, preventing cold air from entering the bottom of the casing, which is partitioned by a heat insulating board, and dust from entering. It can prevent it from falling.
