Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to a tap water pressurization and stabilization device. Background Technology

[0002] A water supply system is a pipeline system that transports water from a water source (such as a reservoir, well, or water treatment plant) to user terminals (households, industrial facilities, or commercial facilities). Its design, material selection, and maintenance directly affect water supply efficiency, water quality safety, and system lifespan. In a water supply system, the collector collects water from the source, which is then boosted by a variable frequency pump and distributed to each point of use by the distributor. During the boosting process, unstable water pressure can easily occur, and eddy currents can be generated after the booster pump delivers the water, which can easily damage the water pipes and affect their service life.

[0003] Patent application CN201220356103.8 discloses a novel intelligent dual-source constant pressure water supply device, comprising an inlet pipe, a water tank, a suction pipe, a distributor, a water pump, a water collector, a pressure stabilizing tank, a remote pressure gauge, and an intelligent control device. The water tank and suction pipe are each connected to the inlet pipe; the water tank is connected to the distributor via an outlet pipe and a suction pipe. The intelligent control device uses a large-panel operating interface, a dual-core, multi-signal control system, and utilizes the residual pressure of tap water for pressurized water supply. When the water pressure is insufficient, it automatically draws water from the tank for supply. The dual-core, multi-signal control system and large-panel operating interface enable direct communication with... This invention relates to a municipal water supply system with a series connection to a negative pressure-free system. It utilizes residual pressure for energy-saving water supply, automatically ensuring water demand. The system operates stably and offers significant energy savings. It solves the problems of high-rise buildings where negative pressure generated by pumps prevents pressurization equipment from utilizing residual pressure, leading to energy waste. Furthermore, it addresses the issues of small storage tank capacity, high cost, and the need to shut off water supply when the supply is less than the pumping volume. While the device includes a pressure-stabilizing tank at the collector terminal for pressure stabilization, the water distributor and collector in the pipeline operate in a unidirectional manner. Sudden pressure changes during water transport cause water eddies, increasing pipe pressure and potentially leading to pipe rupture. Therefore, this invention discloses a tap water pressurization and stabilization device to address these problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] As described in the background section, in a water supply system, a water collector collects water, which is then pressurized by a frequency converter and distributed to each point of use via a distributor. During the pressurization process, unstable water pressure can easily occur, and eddies can form after the water is pumped, potentially damaging the water pipes and affecting their lifespan. While a pressure stabilizing tank is installed at the end of the water collector to stabilize the pressure, the distributor and collector in this water pipeline operate in a unidirectional manner. During water delivery, sudden changes in water pressure can occur, generating water eddies, increasing pipe pressure, and potentially causing pipe rupture.

[0025] To solve this technical problem, this utility model provides a tap water pressurization and stabilization device, which is applied in the field of water supply equipment.

[0026] For details, please refer to Figure 1-3 The tap water pressurization and stabilization device specifically includes a water collector 1, a water distributor 2, and a pressure stabilizing tank 3. The inlet of the water collector 1 is connected to a water source 5, and the outlet of the water collector 1 is connected to the inlet of the water distributor 2 through a water supply pipeline 7 with a booster pump 6. The outlet of the water distributor 2 is connected to multiple distribution branches 8. The water distributor 2 is connected to the pressure stabilizing tank 3. A constant pressure pipe 9 is connected between the water collector 1 and the water distributor 2. A constant pressure device 10 is provided on the constant pressure pipe 9, and a pressure sensor 11 is provided on the water distributor 2. The intelligent control system 4 has a human-machine interface panel 12. The intelligent control system 4 controls and adjusts the start, stop, and speed of the booster pump 6 according to the signal from the pressure sensor 11 to maintain the target pressure value of the water.

[0027] The water pressurization and stabilization device provided by this utility model pressurizes and delivers water source 5 from water collector 1 to water distributor 2 through booster pump 6, and then distributes it to various distribution branches 8 through water distributor 2, thereby supplying water to each water source 5 usage point. At the same time, pressure sensor 11 monitors the outlet water pressure in real time and transmits the data to intelligent control system 4. Intelligent control system 4 adjusts and controls booster pump 6 to form closed-loop control and adopts fully automatic control, reducing the need for manual intervention and improving system reliability. The pressure stabilizing tank 3 can absorb instantaneous pressure fluctuations to ensure stable water pressure output. At the same time, a constant pressure device 10 is set between water collector 1 and water distributor 2 to keep the pressure constant in water collector 1 and water distributor 2, buffering water pressure changes, ensuring water pressure stability, suppressing water eddy phenomenon, protecting water pipes from impact damage, and extending the service life of water pipes.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1

[0032] Please refer to Figure 1 , 3A water pressurization and stabilization device is provided, comprising a water collector 1, a water distributor 2, a pressure stabilizing tank 3, and an intelligent control system 4. The inlet of the water collector 1 is connected to a water source 5, which is tap water. The water collector 1 is used to collect the tap water intake, increasing the inlet pipe diameter of the pump and acting as a buffer for the tap water. The outlet of the water collector 1 is connected to the inlet of the water distributor 2 through a water supply pipeline 7 equipped with a booster pump 6. The outlet of the water distributor 2 is connected to multiple distribution branches 8. The booster pump 6 pressurizes the water source 5 and outputs it to the water distributor 2, which then delivers it to each distribution branch 8. The distribution branches 8 are connected to water points, thereby supplying water to the water points. The water distributor 2 is connected to the pressure stabilizing tank 3, and the water is collected from the water source 5. A constant pressure pipe 9 connects the water heater 1 and the water distributor 2. A constant pressure device 10 is installed on the constant pressure pipe 9. The constant pressure device 10 is a mechanical constant pressure valve. The mechanical constant pressure valve adopts an existing finished structure. Because the water usage point of the distribution branch 8 is too large at any moment, the valve is closed instantly after the water usage point is finished. The pressure stabilization method of the booster pump 6 cannot reduce the system pressure in a very short time, resulting in excessively high system pressure. The mechanical constant pressure valve can release pressure and play a stabilizing role. In addition, the mechanical constant pressure valve buffers sudden water pressure changes and suppresses water eddy phenomenon through the spring preload and fluid dynamic balance principle. Together with the pressure stabilizing tank 3, it can effectively reduce the water hammer effect and extend the service life of the booster pump 6, various valves in the pipeline and pipeline.

[0033] A pressure sensor 11 is installed on the water distributor 2. The intelligent control system 4 has a human-machine interface panel 12, equipped with a touch screen to display pressure data, pump status, and fault information in real time. It supports manual / automatic mode switching. Based on the signal from the pressure sensor 11, the intelligent control system 4 controls and adjusts the start, stop, and speed of the booster pump 6 to maintain the target water pressure value, which is 0.3~0.5MPa in this example. The intelligent control system 4 is a PLC control system. It achieves precise constant pressure through the linkage between the pressure sensor 11 and the intelligent control system 4. Through the synergistic effect of the constant pressure device 10 and the closed-loop control system, water pressure fluctuations and water eddies are eliminated, the pipeline is protected from impact damage, and the water pressure stability is significantly improved.

[0034] The water supply pipeline 7 is made of DN100 stainless steel. The inner wall of the stainless steel pipeline is smooth to reduce frictional resistance and improve the delivery efficiency. The water supply pipeline 7 is equipped with two booster pumps 6, which are connected to the same delivery pipeline on the water distributor 2, so that one is on standby and the other is in use. This ensures the water pressure from the water distributor 2 to each distribution branch 8. The booster pumps 6 are variable frequency booster pumps and the pump speed is controlled by an ABB frequency converter. The ABB frequency converter is electrically connected to the intelligent control system 4. The intelligent control system 4 automatically controls the variable frequency booster pumps 6 through the transmission signal of the pressure sensor 11. It can adjust the power according to the real-time demand, avoid ineffective energy consumption, and achieve a comprehensive power saving rate of 20%~30%, saving costs.

[0035] The connection nodes between the water supply pipeline 7 and the water collector 1, the booster pump 6 and the water distributor 2 are all equipped with corrugated pipes. The corrugated pipes can reduce the impact vibration of water flow and improve the service life of the pipeline, pump and valve.

[0036] This tap water pressurization and stabilization device is mainly used in:

[0037] 1. Secondary water supply for high-rise buildings: solves the problem of insufficient or fluctuating water pressure caused by differences in floor height, and ensures stable water supply for top-floor users.

[0038] 2. Industrial circulating water system: Applied to scenarios such as production line cooling water and boiler water supply, ensuring continuous and stable operation of equipment.

[0039] 3. Intelligent irrigation in agriculture: Uniform sprinkler irrigation is achieved through constant pressure control, thereby improving water resource utilization.

[0040] 4. Municipal pipeline renovation: Optimize the pressure distribution of old pipelines and reduce the risk of pipe bursts.

[0041] Example 2

[0042] The tap water pressurization and stabilization device provided in Embodiment 1 is further optimized, specifically, as follows: Figure 2 As shown, a one-way valve 13 is installed on the connecting pipeline between the pressure stabilizing tank 3 and the water distributor 2. A pressure reducing valve 14 is installed on the pressure stabilizing tank 3. The water distributor 2 is connected to the pressure stabilizing tank 3 through a stainless steel pipe. The one-way valve 13 is installed on the stainless steel pipe. The pressure inside the pressure stabilizing tank 3 is lower than the water pressure in the water distributor 2. The pressure inside the pressure stabilizing tank 3 is controlled by the pressure reducing valve 14. At the same time, the pressure reducing valve 14 can be a solenoid valve. Through electrical connection with the intelligent control system 4, automatic control is realized. When the water pressure in the water distributor 2 suddenly rises, the pressure stabilizing tank 3, as an auxiliary energy storage unit, can absorb the instantaneous pressure fluctuation, ensure stable water pressure output, and at the same time, prevent the excessive pressure in the pressure stabilizing tank 3 from affecting the water pressure in the water distributor 2.

[0043] Example 3

[0044] The tap water pressurization and stabilization device provided in Embodiment 2 is further optimized, specifically, as follows: Figure 1 , 3As shown, the intelligent control system 4 is equipped with a pressure threshold protection function and is connected to an alarm 15, which can be a buzzer or an alarm light. When the pressure in the water distributor 2 exceeds the preset pressure threshold, the alarm 15 sounds an alarm to alert the staff. At the same time, the intelligent control system 4 controls the booster pump 6 to stop to prevent pipeline damage. Furthermore, it is equipped with a communication module 16, which is installed on the human-machine interface panel 12. The communication module 16 is connected to a remote monitoring device 17. The communication module 16 can be a wired communication module, such as an Ethernet module or a serial communication module, or a wireless communication module, such as a cellular network module or a short-range wireless module (Wi-Fi, Bluetooth, ZigBee, etc.). The remote monitoring device 17 can be a mobile device or a PC, used for real-time monitoring of the water source 5 to achieve remote monitoring.

[0045] Of course, the tap water pressurization and stabilization device also includes some switching valves, power supply, etc., which are existing conventional technologies and will not be described in detail here.

[0046] The working principle of the tap water pressurization and stabilization device provided by this utility model is as follows: the water source 5 in the water collector 1 is pressurized and transported to the water distributor 2 by the booster pump 6, and then distributed to each distribution branch 8 by the water distributor 2, thereby supplying water to each water source 5 usage point. At the same time, the pressure sensor 11 monitors the outlet water pressure in real time and transmits the data to the intelligent control system 4. The intelligent control system 4 adjusts and controls the booster pump 6 to form a closed-loop control, and adopts fully automatic control, reducing the need for manual intervention and improving system reliability. The pressure stabilizing tank 3 can absorb instantaneous pressure fluctuations to ensure stable water pressure output. At the same time, a constant pressure device 10 is set between the water collector 1 and the water distributor 2 to keep the water collector 1 and the water distributor 2 at constant pressure, buffering sudden water pressure changes, ensuring water pressure stability, suppressing water eddy current phenomenon, protecting water pipes from impact damage, and extending the service life of water pipes.
