Problems solved by technology

However, this kind of technology will increase the overall volume of the water meter, increase the complexity of the water meter structure, increase the probability of water meter failure, and the manufacturing and use costs are high
At present, there is no technical solution to prevent freezing and cracking through the change of the watch case itself. Therefore, a water meter anti-freezing method and system are proposed.

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below.

[0026] The embodiment of the water meter that avoids freezing and cracking of the present invention, its schematic diagram is as figure 1 As shown, it is characterized by:

[0027] The water meter case contains an inwardly curved portion that extends outward when squeezed by ice.

[0028] In a preferred embodiment, the position of the inwardly curved part in the water meter is one or more of the central area of ​​the bottom of the case and / or the bottom edge of the case and / or the area between the bottom edge of the case and the center of the bottom of the case. Location.

[0029] In a preferred embodiment, the position of the inwardly curved part in the water meter is symmetrical.

[0030] In a preferred embodiment, the curved shape of the inwardly curved portion is any one or more of a concave arc, a concave square, a concave fold, and a concave irregular shape. Such as figur...

Abstract

The invention discloses a water meter capable of avoiding freezing cracking. The water meter is characterized in that the water meter shell comprises an inward bent part, and the inward bent part extends outwards when being frozen and extruded. According to the method and the system, the technical problem of how to prevent freezing and cracking through the change of the water meter shell is solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent water meters, in particular to a water meter which can avoid freezing and cracking. Background technique [0002] The current intelligent antifreeze water meters are mainly antifreeze by adding insulation jackets or integrated heating devices or emptying the water in the water meters or adding buffer layers or magnetic stirring or ultrasonic vibration. For example, the Chinese patent "An Explosion-proof Water Meter Structure" with the publication number CN101532860B proposes that the bottom surface and the side surface inside the watch case base are provided with an elastic layer, so as to realize all-round protection for the watch case base. The Chinese patent "An Antifreeze Water Meter" with the publication number CN106052786A proposes that the cavity of the water meter is connected with a cavity, and the cavity has a closed space that can be compressed. When the water in the water meter fre...
