There is no limit to creativity, and the instrument is invented. Today we introduce a national invention patent for authorization - an antifreeze and antifreeze type smart water meter . The patent was applied by Jiangsu Guoneng Instrument Technology Co., Ltd. and was authorized to be announced on May 17, 2017.
Description
The utility model relates to the technical field of water meters, in particular to an anti-freeze and anti-freeze type smart water meter.
Background of the invention
Meters for measuring water flow by water meters are mostly measured by cumulative flow of water. They are generally classified into two types: volumetric water meters and speed water meters. The meter used to record the water consumption of tap water is installed on the water pipe. When the user releases the water, the pointer or the word wheel on the watch indicates the amount of water passing through.
With the advancement of society, more and more intelligent products have entered our lives, and intelligent water meters have appeared more and more in our lives, bringing great convenience to the management and reading of water meters. .
In life, the water meter is mostly installed outdoors. In the case of cold weather in winter, it is easy for the water meter to freeze, which causes the water meter to be unable to work effectively, and the water in the water meter becomes large after freezing, which may result in The broken glass on the dial caused trouble for people's daily life. Especially at the end of 2015, the cold air suddenly cooled down. The temperature in the country, especially in the south, reached minus 10 degrees. The residential water meter occurred in the environment of minus 10 degrees. Most of the phenomenon of freezing cracks and freezing is caused by the water flow overnight, which brings great trouble to the people 's life and cannot be used normally. According to the installation environment and use characteristics of the water meter, the water meter glass part has always been tempered glass, transparent and convenient for reading. It is necessary to design and develop anti-freeze water meter glass instead of tempered glass, which can prevent the water meter from cracking and no leakage under the environment of 30°C under zero. Does not affect the residents' normal living water.
Summary of the invention
In order to overcome the deficiencies of the prior art, the utility model provides an anti-freeze and anti-freeze type smart water meter, which enhances the frost resistance of the water meter by changing the shape and material of the anti-freeze glass of the water meter.
The figure is a schematic diagram of the structure of the antifreeze and antifreeze type smart water meter of the utility model
In order to solve the technical problems in the background art, the utility model provides an anti-freeze and anti-freeze type smart water meter, which comprises a water meter shell, a water meter movement, a water meter glass and a copper cover, wherein the water meter movement is arranged in the water meter housing. The copper cover is fixed above the water meter housing, the water meter glass is embedded in the copper cover, the water meter glass includes a first circular table and a second circular table, and the diameter of the first circular table is larger than the diameter of the second circular table. The second circular table is disposed on the first circular table.
Further, the upper surface of the copper cover is provided with a circular opening, and the circular opening is not smaller than the second circular table. The second circular table protrudes from the circular opening, and an upper surface of the first circular table is fitted to an inner surface of an upper surface of the copper cover, and a side surface of the first circular table and an inner side of the copper cover The second circular table protrudes from the circular opening, and the side wall of the second circular table is attached to the hole wall 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 ranges from 7:10 to 9:10. The thickness of the second truncated cone 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.
Further, a water meter upper cover is further included, and the water meter upper cover is pivoted on the copper cover. The water meter glass is injection molded by PA12 at one time. The water meter movement is a smart water meter movement.
The utility model has the beneficial effects that the anti-freeze and anti-freeze type smart water meter of the utility model replaces the original tempered glass by using a convex water-type antifreeze glass made of transparent nylon, and the anti-freezing performance of the water meter is achieved without affecting the reading of the water meter. Better, it can prevent the water meter from rupturing and no leakage under the environment of 30°C under zero temperature, and does not affect the normal living water of residents.
