[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national invention-invented patent—an antifreeze antifreeze smart water meter. The patent was applied by Jiangsu Tianzige New Material Technology Co., Ltd. and was authorized to be announced on March 23, 2018.
Content Description
The invention relates to the technical field of water meters, in particular to an antifreeze antifreeze smart water meter.
Background of the invention
Meters for measuring water flow in water meters are mostly cumulative flows of water. They are generally divided into two types: volumetric water meters and speed water meters. Meter used to record the water consumption of tap water is installed on the water pipe. When the user discharges water, the pointer or wheel rotates on the watch to indicate the amount of water passing through.
With the progress of society, more and more intelligent products have entered our lives. Intelligent water meters have also appeared more and more in our lives, bringing great convenience to the management and reading of water meters. .
In daily life, water meters are mostly installed outdoors. In cold weather in winter, water freezes easily, causing the water meter to work effectively, and the water in the water meter may become large after freezing, which may cause The broken glass on the dial has caused troubles for people's daily life. Especially at the end of 2015, the cold blast air suddenly cooled. The temperature in the whole country, especially in the south, reached minus 10 degrees, and the water consumption of the residents' lives was under minus 10 degrees. Most of the phenomena of frost cracking and freezing damaged the flow of water overnight, causing great trouble to the people's lives and their ability to use normal water. For the installation environment and use characteristics of the water meter, the glass part of the water meter has always been tempered glass, transparent and easy to read, now need to design and develop antifreeze water meter glass instead of tempered glass, can guarantee the water meter is not broken, no leakage under the temperature of minus 30 °C. , does not affect the normal life of residents.
Summary of the Invention
To solve the existing problems, the present invention provides an antifreeze antifreeze smart water meter, which can enhance the antifreeze performance of the water meter by changing the shape and material of the antifreeze glass of the water meter.
The figure is a schematic structural view of the invention
In order to solve the technical problems in the background, the present invention provides an antifreeze antifreeze smart water meter which includes a water meter housing, a water meter movement, a water meter glass and a copper cover. The water meter movement is arranged in the water meter housing, and the copper cover is fixed on the water meter. Above the housing, the water meter glass is embedded in the copper cover. The water meter glass includes a first round table and a second round table. The diameter of the first round table is larger than the diameter of the second round table, and the second round table is arranged on the first round table.
The upper surface of the copper cover is provided with a circular opening, and the circular opening is not smaller than the second round table. The second circular table protrudes from the circular opening, and the upper surface of the first circular table is attached to the inner surface of the upper surface of the copper cover; the side of the first circular table is attached to the inner surface of the copper cover; and the second circular table protrudes from the circular opening. And the side wall of the second circular table is attached to the wall of the hole of the circular opening. The second circular table is concentrically arranged with the first circular table, and the diameter ratio of the second circular table to the first circular table is in the range of 7:10-9:10. The thickness of the second frustum is equal to the thickness of the upper surface of the copper cover, and the upper surface of the water meter glass is flush with the upper surface of the copper cover. It also includes a water meter cover, which is pivotally mounted on a copper cover. The water meter glass is disposable injection molded from PA12. The water meter movement is a smart meter movement.
The beneficial effects of the present invention are: the antifreeze antifreeze smart water meter of the present invention replaces the original tempered glass with a convex water meter antifreeze glass made of transparent nylon, so that the antifreeze performance of the water meter is better without affecting the reading of the water meter. , It can resist zero-under 30 °C environment to ensure that the water meter does not break, no leakage, does not affect the normal life of residents.

Welding Rope
Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
