Description

Technical Field

[0001] The utility model belongs to the field of water meters, in particular to an antifreeze type water meter. Background Art

[0002] Water is used everywhere in life, and water resources are a precious resource, so people have been implementing water-saving awareness, and the application of water meters has a certain driving effect on water conservation.

[0003] A water meter is an instrument that monitors water volume. Water meters are used in a variety of scenarios, such as homes, factories, supermarkets, municipalities, etc. If you want the water meter to play its due role, it must be guaranteed to work normally and be able to adapt to harsh conditions such as low temperatures. However, the common water meters in life do not have antifreeze functions. For example, in homes, if you want to ensure the normal operation of the water meter and prevent it from being frozen in low temperature weather, you will wrap it to increase the temperature inside the water meter, or use hot water for irrigation. However, these cannot truly prevent the water meter from freezing, which will cause the water meter to monitor the water volume inaccurately or damage the water meter.

[0004] To prevent freezing of water meters, heating or thermal insulation materials need to be added. For example, the heating or thermal insulation materials are integrated with the water meter. However, the service life of the heating or thermal insulation materials is shorter than that of other parts of the water meter. When the heating or thermal insulation materials of the integrated structure fail, the antifreeze effect will fail. Therefore, a new structure is proposed to solve the above technical problems.

[0005] In some places in life, water meters are not used during certain periods of time. For example, when family members are away for a long time, some water will still remain in the water meter after the main valve is closed. When low temperature weather suddenly arrives, the water in the water meter will cause the temperature inside the water meter to be too low, and the freezing of water will also damage the internal components of the water meter. Therefore, a new structure is proposed to solve the above technical problems. Utility Model Content
