Description

Technical Field

[0001] The utility model belongs to the technical field of anti-freezing water meters and relates to a water meter for preventing ice formation. Background Technique

[0002] A water meter, as an instrument for measuring water flow, is an important and indispensable device in modern society. It is widely used in various fields such as households, commercial buildings, public facilities, and industrial production, and plays a crucial role in monitoring and managing the use of water resources. In areas with relatively low winter temperatures, if the water meter cannot provide self-heating protection for its interior, a series of problems will occur. These problems not only affect the normal use of the water meter but may also pose potential safety hazards to the entire water supply system.

[0003] An anti-freezing water meter lacking self-heating protection is prone to freezing in a low-temperature environment. When the external temperature drops below the freezing point, the water inside the water meter will freeze, causing the mechanical components and pipes inside the water meter to be covered by ice layers and unable to work properly. This not only makes the water meter unable to accurately measure the water consumption but may also damage the structure of the water meter due to the expansion of the ice layer. Therefore, there is an urgent need for a water meter for preventing ice formation to solve the above problems. Summary of the Utility Model

It is possible to prevent external water bodies from entering the inside of the upper shell 100 by using the anti-ice covers 120 and the sealing gaskets 130.

[0026] The model of the electronic water meter is LSY-DN15. A set of connecting pipes 160 for exporting water is provided on the right side of the electronic water meter.

[0029] The upper shell 100 and the lower shell 140 are interlocked and fixedly connected by bolts, and the upper shell 100 and the lower shell 140 are sealed by a sealant layer. The upper shell 100 and the lower shell 140 are both provided with an insulating inner layer.

[0032] See also Figures 1-4As the first embodiment of the utility model: In order to solve the problem that the antifreeze water meter lacking self-heating protection is prone to freezing in a low temperature environment, when the outside temperature drops below the freezing point, the water inside the water meter will freeze, causing the mechanical parts and pipes inside the water meter to be covered with ice and unable to work normally. First, when the external temperature is as low as the freezing point, the staff heats the heating coil 19c inside the heating ring sleeve 190 and transfers the temperature to the inside of the water pipe through the inner thermal conductive sleeve 19d, which can effectively prevent the water from freezing while increasing the temperature between the upper shell 100 and the lower shell 140. Since the upper shell 100 and the lower shell 140 are interlocked with each other and fixedly connected by bolts, and the upper shell 100 and the lower shell 140 are sealed by a sealant layer, the upper shell 100 and the lower shell 140 are both provided with an insulating inner layer, and the insulating inner layer can effectively prevent heat dissipation to ensure that the water meter can be used stably in a low temperature environment.
