Description

Technical Field

[0001] The utility model belongs to the field of thermal insulation water meters, and in particular relates to a water meter with thermal insulation functions. Background Art

[0002] As the pace of urbanization continues to accelerate and cities continue to develop, tap water is connected to every household, water convenience is improved, and people's living standards are also improved. However, with the popularization of tap water, water meters are found in daily use that when the winter cold wave comes, due to the drop in temperature, the water meters shipped from the factory have no insulation measures. At the same time, the water meter is a metal component with strong thermal conductivity, and the water in the water meter will freeze and damage the water meter. After the water meter is damaged, due to water pressure, a large amount of water will be lost, causing economic losses to the company. If the water meter is indoors, it may cause the home to be soaked, causing significant economic losses to the family. How to ensure the insulation of the water meter is particularly important. At present, the insulation of the water meter is mainly carried out by secondary binding of insulation cotton after the water meter is installed. There is a gap between the water meter and the insulation effect is poor. At the same time, the insulation material used is a flexible material similar to a sponge, and it is easy to be damaged without basic protection measures. For indoor water meters, users basically have no awareness of insulation when replacing water meters. Utility Model Content

[0006] As a supplement to the present invention, the heat-insulating shell is a rectangular parallelepiped structure.

[0007] As a supplement to the present invention, the thermal insulation cotton and the thermal insulation shell are connected by using waterproof glass glue.

[0008] As a supplement to the present invention, the upper cover is connected to the heat-insulating shell on one side by a hinge, and a buckle that cooperates with each other is provided on the other side.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0019] As shown in the figure, a water meter with thermal insulation function described in the utility model includes a water meter body 1, thermal insulation cotton 2, a thermal insulation shell 3, and an upper cover 4. The thermal insulation cotton 2 is arranged in the thermal insulation shell 3 (the top of the thermal insulation shell 3 is open), and the interior of the thermal insulation cotton 2 is a cavity 5 in the shape of a water meter. The water meter body 1 is arranged in the cavity 5, and the connecting heads 6 on both sides of the water meter body extend out of the thermal insulation shell 3. The upper cover 4 is movably arranged above the thermal insulation shell 3, and an observation hole 7 is provided on the upper surface of the thermal insulation cotton 2. The back of the upper cover 4 is provided with an insulation layer 8 corresponding to the observation hole 7.

[0020] The utility model discloses a water meter with heat insulation function, the water meter is an ordinary mechanical water meter (no cover is required, and the reading can be directly read), the connectors 6 on both sides of the water meter are connected to the pipeline through threads, and the outer side of the water meter body 1 is a heat insulation cotton 2, such as Figure 2 As shown, the overall shape is a rectangular parallelepiped. In order to better fit the water meter, the internal shaping of the thermal insulation cotton adopts a mold in the shape of a water meter to form a cavity 5 in the shape of a water meter. When the thermal insulation cotton is combined with the side of the water meter, it can fit tightly. The thermal insulation cotton is divided into left and right parts, which are matched together by the convex rod 10 and the groove 11. Figure 3 As shown, it can be opened for maintenance.

[0021] The insulation shell 3 is made of hard plastic and has a rectangular shape. The hollow insulation cotton 2 inside can be embedded in the shell. In order to ensure that the insulation cotton is firmly connected to the insulation protective shell, waterproof glass glue is used. In order to facilitate the viewing of the water meter reading, an observation hole 7 is provided on the upper surface of the insulation shell 3. In order to prevent the observation hole 7 from not being insulated, an openable upper cover 4 is installed on the insulation shell 3. An insulation layer 8 is provided on the back of the upper cover 4. After the upper cover 4 is closed, the insulation layer 8 covers the observation hole 7. The upper cover 4 is connected to one side of the insulation shell 3 by a hinge, and the other side is provided with a matching buckle 9. For easy maintenance, the insulation shell 3 can be opened from the middle to match the insulation cotton, and the bottom is connected by a hinge.

[0022] The observation hole 7 of the utility model is a round hole, which is slightly larger than the reading window of the water meter, and it is convenient to read the water meter by opening the upper cover.

[0023] When the water meter leaves the factory, it is already attached with thermal insulation cotton, and a protective shell is used for the thermal insulation cotton, and waterproof glass glue is used to connect it, which not only improves the thermal insulation of the water meter and avoids the secondary construction of the thermal insulation cotton on site, but also improves the durability of the thermal insulation cotton. At the same time, the thermal insulation cotton and the thermal insulation protective shell can also be opened from the middle to facilitate the maintenance of the water meter.

[0024] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
