Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a heat-insulating cover for water meters installed in mid-to-high-rise buildings.

(Conventional technology) Currently, many of the water meters installed in mid-to-high-rise buildings such as condominiums are not insulated, so many of them freeze and break during abnormally cold waves.
The industry is strongly requesting measures to prevent water meters from freezing, as they require a large amount of repair and other expenses.

As a meter cover of this type, the applicant covers a plurality of divided insulation materials for housing a water meter and a water supply pipe with a thin cover and a bottom plate, and fastens the cover and the bottom plate with screws. Developed a structure. A structure similar to this is known from Japanese Utility Model Application Publication No. 116452/1983.

(Problem that the invention aims to solve) In these conventional meter covers, the thin plastic cover and bottom plate tighten and integrate the divided insulation materials, so there are parts without insulation material. Moreover, the thin hard plastic on the outside could not be expected to have a great insulation effect, resulting in insufficient heat retention. Secondly, the cover/bottom plate made of hard plastic has a complicated shape and is expensive to manufacture. Furthermore, because it takes time to disassemble and assemble the plastic cover and bottom plate, it is difficult to quickly read and inspect the meter of the water meter.

(Means for Solving the Problems) The present invention aims to solve these problems and provide a practical water meter insulation cover for mid-to-high-rise buildings that is inexpensive, has good heat retention, and allows for quick and easy meter reading and inspection. Its gist is that it has a stepped rectangular parallelepiped shape that has a housing fitting part for the water meter and the water stop valve, has an open scale part of the water meter, and is divided into two parts perpendicularly to the longitudinal direction. It consists of an inner protective cover and a box-shaped outer protective cover that is inserted from the outside and fitted with the cover to tighten and integrate the inner protective cover, and the upper surface of the outer protective cover has an area of at least half of the upper surface. A viewing window is opened, and a window of 1
A water meter heat-insulating cover for medium-to-high-rise buildings, characterized in that two lid plugs are detachably attached, and the inner protective cover, the outer protective cover, and the lid plug are all made of thick-walled foamed plastic. be.

(Function) In this invention, the inner protective cover made of foamed plastic is covered with the outer protective cover made of foamed plastic of the same thickness and the lid plug made of thickened foamed plastic, so the heat retention is high and the structure is rectangular parallelepiped. Not only is it box-shaped, it is simple, and the entire structure is made of foamed plastic, which greatly reduces costs.Furthermore, reading the meter of the water meter is as simple as lifting the lid, and even if there are water drops or cloudiness on the dial, you can easily read it by hand. However, it can be removed immediately and the meter can be read accurately. Inspection and replacement of water stop valves and water meters can be quickly disassembled by simply pulling up the outer protective cover.

(Example) Examples will be described below based on the drawings.

FIG. 1 shows a perspective partial cross-sectional view of the present invention, in which 1 is an outer protective cover and 2 is a lid plug. It is inserted into a contact fit to ensure sufficient confidentiality. Reference numerals 3 and 3' denote inner protective covers, which are divided into two parts perpendicularly to the longitudinal direction. Inside the inner protective covers 3 and 3', there are water meter storage parts 4 and 4' for storing a water meter, a water stop valve storage part 5 for storing a water stop valve, and pipe storage parts 6 and 6', respectively. It is being formed.

Figure 2 shows the water meter cover for medium and high-rise buildings of the present invention, which includes a water meter 7, a water stop valve 8, and a water pipe 9.
It is a perspective view showing an example of an assembly method for attaching the water meter 7 to the water meter 7, in which the inner protective covers 3, 3' are joined from both sides of the water meter 7, the water meter 7 is stored in the storage parts 4, 4', and the water meter 7 is stopped at the same time. After storing the faucet 8 in another stop valve housing 5 and closing the above-mentioned inner protective covers 3 and 3', the outer protective cover 1 is replaced with the inner protective cover 3,
3' from above and cover and fit the inner protective covers 3, 3' together.

(Effects of the invention) As described above, according to the invention, (1) Water meters and water stop valves in mid-to-high-rise buildings have high heat retention properties, so freezing damage can be effectively prevented.

(2) Since the cap can be easily attached and removed, the water meter can be read quickly, and even if there are water drops or cloudiness on the dial, you can easily remove them by hand and read the meter accurately.

(3) The entire unit can be disassembled and reassembled simply by pulling up or pushing down the outer protective cover, allowing quick inspection and repair of water stop valves and water meters.

There is an effect.
