Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of domestic water, and in particular to a domestic water system using intelligent water meters, automatic water inlet valves and buffer tanks. BACKGROUND

[0002] The normal accuracy range of domestic water meters is usually ±2%. Taking a water meter as an example, according to the national standard, the accuracy of a water meter is generally required to be within ±2%, which means that the deviation of the meter reading from the actual water consumption should be within ±2%. In addition, the accuracy requirements of domestic intelligent water meters under different flow conditions are also specified:

[0003] Minimum flow (Qmin): the cumulative indication error should not exceed ±5%;

[0004] Threshold flow (Qt): the cumulative indication error should not exceed ±2%;

[0005] Normal flow (Qn): the cumulative indication error should not exceed ±2%;

[0006] Maximum flow (Qmax): the cumulative indication error should not exceed ±2%.

[0007] Factors affecting the accuracy of water meters include manufacturing quality, design structure, installation conditions, use environment and maintenance, etc. High-quality materials and precise processing technology can improve the accuracy of water meters, while the choice of installation location, water quality conditions, temperature changes and regular calibration and cleaning and maintenance will also affect its accuracy. In order to ensure the accuracy of water metering, users should choose reliable water meter brands and models, and regularly check and maintain them. Generally, the measurement error of a measuring instrument is the smallest at one-half to two-thirds of the range. The higher the accuracy, the more complex the instrument manufacturing, and the more difficult the maintenance.

[0008] The disadvantages of traditional old water meters compared with intelligent water meters mainly include the following points:

[0009] 1. Low efficiency of manual meter reading: old water meters need to be read manually at regular intervals, which is a large workload and prone to meter reading errors. This method is low in efficiency and is greatly affected by objective factors. Meter readers cannot read the meter at the specified time, and the meter reading date is often advanced or postponed;

[0010] 2. Lack of real-time feedback: old water meters cannot provide real-time water consumption data, and users need to wait for the meter reader to read the meter to know the water consumption, which makes users unable to know their water consumption in a timely manner and manage water use reasonably;

[0011] 3. High maintenance cost: Old water meters are more prone to wear and tear due to their mechanical nature, which not only causes water pollution but also damages the meter itself, leading to measurement errors and high maintenance costs;

[0012] 4. Easy to be used to escape fees: Old water meters do not move when dripping, and some users may take advantage of this to escape fees;

[0013] 5. Technological backwardness: With the development of technology, people's demand for accuracy and convenience of measurement is increasing, and old water meters cannot meet these needs. Smart water meters, through the intelligent meter reading platform, will realize remote meter reading to households, real-time monitoring of pipe networks, intelligent analysis of business operations, and improve meter reading efficiency;

[0014] 6. Unable to achieve intelligent management: Old water meters cannot achieve data remote transmission, including collection, storage, transmission and other steps, and cannot completely get rid of the problems of traditional water meters.

[0015] In summary, old water meters have obvious disadvantages in efficiency, accuracy, real-time, maintenance cost and intelligent management, while smart water meters have significant advantages in these aspects. Therefore, it is inevitable trend to replace old water meters with smart water meters, and the data analysis function of smart water meters has the following advantages:

[0016] 1. Water behavior characteristics and habits: By analyzing the data collected by smart water meters, users' water behavior characteristics and habits can be obtained, and users' water usage patterns and preferences can be understood;

[0017] 2. Water measurement: Smart water meters can provide accurate water measurement to help water companies and users understand the specific water usage;

[0018] 3. Detection of abnormal water behavior: Data analysis can help detect abnormal water behavior, such as water leakage or water stealing, and timely maintenance and management;

[0019] 4. Water resource conservation: By analyzing users' water data, water companies can find users' water waste behavior and take targeted measures to remind users to save water;

[0020] 5. Improve service quality: Data analysis of smart water meters can help water companies improve service quality by analyzing water data to predict users' water demand and take appropriate measures to ensure water supply;

[0021] 6. Water demand prediction: Smart water meters predict users' water demand by analyzing users' historical water data and water habits, combined with algorithm models, to help water companies adjust water supply plans;

[0022] 7. Water optimization: Analysis and mining of smart water meter data can be used for water optimization, helping users and water companies to use water resources more reasonably;

[0023] 8. Water saving reminder: When the user's water consumption exceeds a certain threshold, the smart water meter can issue a reminder to guide the user to save water;

[0024] 9. Data reporting: Smart water meters can regularly send users reports on water consumption and water usage frequency, allowing users to be aware of their water usage behavior and providing suggestions to help users reduce water consumption.

[0025] These data analysis functions make smart water meters not just a metering tool, but a smart system that can provide in-depth water insights and optimization suggestions.

[0026] However, there are some problems in the use of smart water meters that need to be paid enough attention to:

[0027] 1. Smart water meter design problem: When the flow is small, the smart water meter is too sensitive, and slight pressure fluctuations in the water flow can cause the meter to read and count. Using mechanical transmission such as wave power generation principle, it is possible to design a smart water meter that can make the meter rotate for counting regardless of positive and negative fluctuations, thus inevitably causing false reading problems, increasing the user's water cost, and technical measures must be taken to eliminate the inaccuracy of small flow from the source. Even if there is a false reading problem in the smart water meter, technical measures can be used to reduce or even eliminate it;

[0028] 2. Household water user usage problem: Users have randomness, temporality, uncertainty, etc. when using water. The start and stop of water facilities will cause water pressure fluctuations and water volume changes, which will cause the smart water meter to be inaccurate.

[0029] In addition, when the water supply pipeline is repaired, it will be stopped in a certain area and time period, and it is necessary to store water for use in the family in time to avoid affecting normal life.

[0030] In view of the above problems, how to solve the stability of the household water system, the accuracy of water metering, and the inconvenience of life and fire emergency caused by water stoppage in the water system through technical means is worth further studying. SUMMARY

[0031] The purpose of the present application is to solve the above problems, and provide a household water system, which adopts smart water meter, automatic water replenishment valve and buffer tank water storage technology, effectively improves the measurement accuracy and stability of the smart water meter of the household water system, and achieves the purposes of saving water resources, saving social public resources, improving people's life quality and life satisfaction.

[0032] A domestic water system characterized in that,

[0033] The domestic water system is provided with a total water supply pipe intelligent water meter 30, a first user intelligent water meter 40, a first user automatic water replenishment valve 41, a first user buffer water tank 43, a second user intelligent water meter 50, a second user automatic water replenishment valve 51, a second user buffer water tank 53, an Nth user intelligent water meter 60, an Nth user automatic water replenishment valve 61, and an Nth user buffer water tank 63, wherein N≥3,

[0034] Domestic water enters the first user intelligent water meter 40, the first user automatic water replenishment valve 41, the first user buffer water tank 43, the first water facility 45, the second user intelligent water meter 50, the second user automatic water replenishment valve 51, the second user buffer water tank 53, the second water facility 55, or the Nth user intelligent water meter 60, the Nth user automatic water replenishment valve 61, the Nth user buffer water tank 63, and the Nth water facility 65 through the total water supply pipe 29 and the total water supply pipe intelligent water meter 30,

[0035] When the first water facility 45 is put into use, water is supplied to the first water facility 45 through the first user buffer water tank 43,

[0036] When the second water facility 55 is put into use, water is supplied to the second water facility 55 through the second user buffer water tank 53,

[0037] When the Nth water facility 65 is put into use, water is supplied to the Nth water facility 65 through the Nth user buffer water tank 63,

[0038] When the water level in the first user buffer water tank 43 is at a set low water level, the first user automatic water replenishment valve 41 is opened to allow water to enter, and when the water level in the first user buffer water tank 43 reaches a set high water level, the first user automatic water replenishment valve 41 is closed to stop water replenishment,

[0039] When the water level in the second user buffer water tank 53 is at a set low water level, the second user automatic water replenishment valve 51 is opened to allow water to enter, and when the water level in the second user buffer water tank 53 reaches a set high water level, the second user automatic water replenishment valve 51 is closed to stop water replenishment,

[0040] When the water level in the Nth user buffer water tank 63 is at a set low water level, the Nth user automatic water replenishment valve 61 is opened to allow water to enter, and when the water level in the Nth user buffer water tank 63 reaches a set high water level, the Nth user automatic water replenishment valve 61 is closed to stop water replenishment,

[0041] The automatic water supplement valve can automatically and stably supplement water to the buffer water tank when the buffer water tank is at a low water level, and the automatic water supplement valve is closed when the water level in the buffer water tank reaches a set high water level, so that the whole water supplement process is continuous and stable, thereby ensuring the stable and accurate measurement of the intelligent water meter; when the water supply facilities are put into use, the water pressure and water volume of domestic water fluctuate, but the buffer water tank can supply water, and the measurement of the intelligent water meter of the first user, the second user or the Nth user is not affected, thereby eliminating the influence of the water pressure and water volume of the traditional water supply facilities on the measurement accuracy of the intelligent water meter and eliminating the influence of the water supply facilities on the water supply system.

[0042] The total water supply pipe automatic water supplement valve 31 and the buffer tank 33 are arranged.

[0043] The domestic water enters the buffer tank 33 through the total water supply pipe 29, the total water supply pipe intelligent water meter 30, the total water supply pipe automatic water supplement valve 31 and the total water inlet pipe 32, and then enters the first user, the second user or the Nth user.

[0044] The first water supply facility 45, the second water supply facility 55 or the Nth water supply facility 65 includes a faucet, a hot and cold faucet, a shower, a washing machine, a dishwasher, a water heater and the like.

[0045] The water heater includes a gas water heater, an electric water heater or a solar water heater.

[0046] The total water supply pipe 29, the first user water inlet pipe 42, the second user water inlet pipe 52, the Nth user water inlet pipe 62 and the water supply pipe between the corresponding buffer water tank and the water supply facility include pipes, pipe fittings and their supports.

[0047] The pipe fittings include elbows, tees, crosses, reducers, pipe caps, plugs and the like.

[0048] The connection between the pipes, the connection between the pipes and the pipe fittings, and the connection between the pipe fittings are achieved by welding, hot melting connection, expansion connection, buckle connection or threaded connection.

[0049] The unexplained facilities in the domestic water supply system refer to or are matched according to the reliable and mature technology in the known water supply pipe.

[0050] Compared with the prior art, the present application has the following advantages:

[0051] 1. Compared with the existing domestic water supply system, the automatic water supplement valve and the buffer water tank arranged in the present application are conventional and mature facilities in industrial applications, but when applied to the domestic water supply system, unexpected technical effects can be achieved:

[0052] (1) Because the automatic water supplement valve can automatically and smoothly supplement water to the buffer tank when the buffer tank is at a low water level, and the automatic water supplement valve is closed when the water level in the buffer tank reaches the set high water level, the entire water supplement process is continuous and smooth, thus ensuring that the intelligent water meter is in an optimal measurement range and guaranteeing stable and accurate measurement of the intelligent water meter. The substantial breakthrough of the present application is that the traditional water use and measurement are synchronized, and are changed into non-synchronous and cumulative intermittent measurement of large flow, so that the measurement of the water meter is in an optimal range;

[0053] (2) When the domestic water facility is put into use, water pressure fluctuation and water quantity change may occur, but because the buffer tank is used for water supply, the measurement of the intelligent water meter is not affected, thus eliminating the influence of water pressure and water quantity change on the measurement accuracy of the water meter when the traditional water facility is put into use, and eliminating the influence of the traditional water facility on the water supply system. The inaccuracy of the user-end water meter measurement and the increase of the user's water cost caused by the pressure fluctuation and water quantity fluctuation of the domestic water are not trivial, and the technical solution of the present application eliminates these disadvantages in a virtual manner.

[0054] (3) Because the buffer tank has the water storage function, when the water supply department carries out pipeline maintenance, and the water is stopped in a certain region and time period, the stored water in the buffer tank can provide the required water for life, and the normal supply of domestic water is not affected.

[0055] (4) The buffer tank has the water storage capacity, and can effectively provide emergency rescue materials in the case of fire caused by water stoppage;

[0056] (5) Because the total water supply pipe intelligent water meter and the user-end intelligent water meter can accurately measure and have very small measurement error, through comparison of the total water supply pipe intelligent water meter and the user-end intelligent water meter, the leakage point or abnormal water use such as water stealing can be easily found, thus providing reliable technical support for the maintenance and operation management of the domestic water system.

[0057] 2. Compared with the prior art, the technical solution of the present application can be applied to a newly-built domestic water system, and can also be applied to the modification of a traditional domestic water system, can fully play the advantages of the intelligent water meter, effectively reduce or even eliminate the disadvantages, has strong universality, low modification cost, and is beneficial to the water company and the user.

[0058] 3. Compared with the existing safety technical specification for the construction of the domestic water supply industry, the technical solution of the present application, if it becomes the general technical specification of the industry, has no doubt and has great social and economic significance.

When the water level in the N-number user buffer water tank 63 reaches the set high water level, the N-number user automatic water supplement valve 61 is closed to stop water supplement,

[0071] Because the automatic water supplement valve can automatically and smoothly supplement water to the buffer water tank when the corresponding buffer water tank is at the low water level, and the automatic water supplement valve is closed when the water level in the buffer water tank reaches the set high water level, the entire water supplement process is continuous and smooth, thus ensuring the stable and accurate measurement of the intelligent water meter. Because the water pressure and water volume of the domestic water fluctuate when the water facility is put into use, but the buffer water tank is used for water supply, the measurement of the first user, second user, or N-number user intelligent water meter is not affected, thus eliminating the influence of the water pressure and water volume changes of the traditional water facility on the measurement accuracy of the intelligent water meter and eliminating the influence of the water facility on the water supply system.
