Description

Technical Field

[0001] This utility model relates to the technical field of water supply network systems, and more specifically, to a pressure equalization regulating valve group for intelligent water supply networks in high-density communities. Background Technology

[0002] With the acceleration of urbanization, the number of high-density communities (such as high-rise residential communities and apartment clusters) has increased significantly. The water supply networks of these communities are characterized by complex pipelines, numerous water points, and drastic fluctuations in water load, with water consumption surging during morning and evening peak hours and sharply decreasing during off-peak hours. Traditional water supply network pressure regulation methods are no longer sufficient to meet the demand, and the main problems are as follows: Poor pressure balance: Traditional water supply networks mostly use fixed pressure water supply or single-point pressure regulation, which cannot dynamically adjust the pressure according to the water demand of different buildings and floors. For example, high-rise residents often experience water outages and reduced water flow due to insufficient pressure at the end of the network, while low-rise residents experience increased leakage rate due to excessive pressure, which can easily lead to damage to water-using equipment such as faucets and water heaters. Slow response: Existing pressure regulation relies heavily on manual inspection or timed adjustment, which cannot detect changes in water load in real time. During peak water usage periods, when the pipeline pressure drops, it needs to be detected manually and valves need to be adjusted manually, resulting in a long response time and a poor user experience. During off-peak periods, the problem of excessive pressure cannot be alleviated in time, resulting in energy waste. Insufficient adaptability: Traditional regulating valve assemblies are mostly single-path designs, which cannot match the complex pipe network structure of high-density communities with multiple branch pipelines, affecting the performance. In view of this, we propose a pressure balancing regulating valve assembly for intelligent water supply networks in high-density communities. Utility Model Content

[0003] The purpose of this invention is to provide a pressure equalization regulating valve group for high-density community intelligent water supply network to solve the defects mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A pressure balancing regulating valve assembly for a high-density community intelligent water supply network includes a main pipeline. A main valve is connected to the end flange of the main pipeline. A guide pipe is connected to the outlet flange of the main valve. A secondary valve is connected to the end flange of the guide pipe. A delivery pipe is connected to the end flange of the secondary valve. Multiple branch pipes are connected to the delivery pipe via flanges, and branch pipe valves are installed on the branch pipes. Ultrasonic flow meters are detachably installed on both the guide pipe and the branch pipes. High-precision pressure sensors are detachably installed on the guide pipe, the inlet pipe of the delivery pipe, and the branch pipes. An intelligent control module with a remote communication module is installed externally on the main pipeline.

[0005] Preferably, a pressure relief pipe is fixedly installed at the end of the conveying pipe, and a pressure relief valve is fixedly installed on the pressure relief pipe; This setting enables pressure relief protection when the internal pressure of the pipeline is too high and pressure needs to be released.

[0006] Preferably, the inner diameter of the pressure relief pipe is smaller than the inner diameter of the delivery pipe, and the main valve, the auxiliary valve, the branch pipe valve, and the pressure relief valve are all electric valves.

[0007] Preferably, threaded cylinders are integrally formed at corresponding positions on the guide pipe, the delivery pipe and the branch pipe, and the ultrasonic flow meter and the high-precision pressure sensor are inserted into the corresponding threaded cylinders. Preferably, both the ultrasonic flow meter and the high-precision pressure sensor have threaded posts fixedly installed on their tops, and the threaded posts are threadedly connected to the threaded cylinder. The above two settings facilitate the installation and removal of ultrasonic flow meters and high-precision pressure sensors.

[0008] Preferably, a sealing cover plate is fixedly installed at the top of the threaded column, and the outer diameter of the sealing cover plate is larger than the outer diameter of the threaded cylinder; Preferably, a sealing gasket is fitted onto the threaded column, and the sealing cover plate presses the sealing gasket tightly against the top surface of the threaded cylinder; The above two settings can improve the sealing effect and reduce leakage.

[0009] Preferably, a knob is fixedly installed at the center of the top surface of the sealing cover, and the knob has a hexagonal cross-section.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes high-precision pressure sensors and ultrasonic flow meters installed on the main pipe, delivery pipe, and branch pipes, combined with an intelligent control module, to achieve real-time monitoring of pressure and flow in different areas of a high-density community water supply network. The intelligent control module dynamically adjusts the opening and closing degrees of the main valve, auxiliary valve, and branch pipe valves based on the monitoring data, precisely adjusting the pressure according to the water demand of different buildings and floors. This effectively solves the problems of insufficient pressure in high-rise buildings and excessive pressure in low-rise buildings caused by traditional fixed-pressure water supply, achieving the effects of balancing network pressure, reducing leakage rates, and protecting water-using equipment.

[0011] 2. This utility model, through the collaboration of an intelligent control module and a remote communication module, combined with electrically operated main and auxiliary valves and other components, achieves automatic adjustment and remote control of water supply network pressure. Without the need for manual inspection or periodic adjustments, the system can sense changes in water load in real time, rapidly increasing network pressure during peak hours to ensure water supply, and promptly reducing pressure during off-peak hours to avoid energy waste. This solves the problem of lag in response of traditional adjustment methods, achieving the effects of improved adjustment efficiency, optimized user water experience, and energy conservation.

[0012] 3. This utility model, through its multi-path design including a main pipe, a connecting pipe, a delivery pipe, and multiple branch pipes, coupled with independent valves and monitoring components on each pipe, achieves adaptation to the complex pipe network structure of high-density communities. Each branch pipe can be independently adjusted according to the water usage of its corresponding area, while the installation of pressure relief pipes and valves can promptly relieve pressure and provide protection when the pipe pressure is too high.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

An intelligent control module 3 is installed on the outside of the main pipeline 1. The intelligent control module 3 is equipped with a remote communication module 30, which enables the high-precision pressure sensor 20 to monitor the pressure of each pipeline in real time, and the ultrasonic flow meter 2 to monitor the flow. After the data is transmitted to the intelligent control module 3, the opening and closing degree of each electric valve can be automatically adjusted.

The inner diameter of the pressure relief pipe 14 is smaller than the inner diameter of the conveying pipe 13. The main valve 10, the auxiliary valve 12, the branch pipe valve 16, and the pressure relief valve 141 are all electric valves, so that when the internal pressure of the conveying pipe 13 is too high, the pressure relief valve 141 can be automatically opened to discharge the excess pressure through the pressure relief pipe 14, thus preventing the pipeline from being damaged due to excessive pressure. At the same time, the main valve 10, the auxiliary valve 12, etc. are all electric valves, which can quickly respond to the instructions of the intelligent control module 3, further ensuring the stability of the pipeline pressure and reducing safety risks.

The threaded posts 21 are threadedly connected to the threaded cylinders 17, allowing the ultrasonic flow meter 2 and the high-precision pressure sensor 20 to be detachably installed through the threaded connection between the threaded posts 21 and the threaded cylinders 17. This allows for installation and removal without disassembling the pipeline, facilitating subsequent maintenance, calibration, or replacement of the monitoring equipment and improving maintenance convenience.

[0018] like Figure 3As shown, a sealing cover plate 22 is fixedly installed at the top of the threaded column 21. The outer diameter of the sealing cover plate 22 is larger than the outer diameter of the threaded cylinder 17. A sealing gasket 24 is fitted on the threaded column 21. The sealing cover plate 22 presses the sealing gasket 24 tightly onto the top surface of the threaded cylinder 17, effectively enhancing the sealing performance of the connection between the threaded column 21 and the threaded cylinder 17, preventing water in the pipeline from leaking from the connection gap, ensuring the efficiency of water transmission in the pipeline network, and reducing water waste.

The operator can use tools or directly hold the knob 23 to rotate the sealing cover plate 22, thereby driving the threaded column 21 to rotate, easily completing the installation or removal of the ultrasonic flow meter 2 and the high-precision pressure sensor 20, reducing the difficulty of operation and improving the installation efficiency.

[0020] It is worth noting that the high-precision pressure sensor 20, ultrasonic flow meter 2, main valve 10, auxiliary valve 12, branch pipe valve 16, and pressure relief valve 141 are electrically connected to the intelligent control module 3, and the remote communication module 30 communicates bidirectionally with the intelligent control module 3; the high-precision pressure sensor 20 is used to collect real-time pressure data of the water supply network and transmit it to the intelligent control module 3; the ultrasonic flow meter 2 is used to collect the total inflow of water into the network and the flow data of each branch pipe and transmit it to the intelligent control module 3; the main valve 10, auxiliary valve 12, branch pipe valve 16, and pressure relief valve 141 are used for...

At the same time, it uploads the pipeline operation data to the cloud monitoring platform through the remote communication module 30 and receives the control parameters sent by the platform. The remote communication module 30 supports 5G / LoRa / NB-IoT communication protocols to realize data interaction between the intelligent control module 3 and the cloud monitoring platform.

[0021] It is worth noting that the high-precision pressure sensor 20 has a measurement range of 0-1.6 MPa, a measurement accuracy of ±0.2%FS, and a sampling frequency of ≥1 Hz; the ultrasonic flow meter 2 has a measurement range of 0-500 m³ / h. 3 / h, measurement accuracy ±1.0%, supports cumulative flow and instantaneous flow acquisition; the ultrasonic flow meter 2 communicates with the intelligent control module 3 via an RS485 interface, with a data transmission cycle ≤10s; the intelligent control module 3 includes a microprocessor, a storage unit, and a power supply unit; the microprocessor adopts an ARM Cortex-M4 architecture with a main frequency ≥168MHz, supporting parallel data processing of multiple modules; the storage unit is used to store pressure balancing algorithms, historical operation data storage duration ≥30 days, and user water load models; the power supply unit adopts a dual power supply of 220V AC mains power + lithium battery backup, with a lithium battery life of ≥48h, ensuring the normal operation of the valve group's basic functions during power outages.
