[0002] With economic development, secondary water supply systems have become an indispensable part of high-quality domestic water use for residents. At the same time, this has increased the pressure on municipal water supply networks. The question is how to alleviate the competition for water from municipal pipelines, especially during peak periods when municipal water supply is being used simultaneously. Meanwhile, there are frequent cases of damage to water outlet pipelines due to excessive system pressurization. How to reasonably and automatically release pressure from excessively high pressure to protect water outlet pipelines in unattended situations has become an urgent technical problem to be solved. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a peak-shaving and storage-based pipeline superimposed pressure (no negative pressure) water supply system. This system can set off-peak and peak states according to different time periods. During off-peak periods, the water storage device replenishes and stores water, while during peak periods, the municipal pipeline water supply is shut off, thereby reducing the pressure on the municipal pipeline water supply and ensuring residents' domestic water use.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] A peak-shaving and pressure-regulating (negative pressure-free) water supply system includes a box-type pressure-regulating (negative pressure-free) water supply system and a pressure-regulating (negative pressure-free) water supply system. The box-type pressure-regulating (negative pressure-free) water supply system includes a water replenishment device, a water storage device, a disinfection device, and a booster device. The pressure-regulating (negative pressure-free) water supply system includes a municipal water replenishment device, a booster pump set, and a pressure relief device. This water supply system mainly replenishes the system by activating different water supply modes according to peak and off-peak periods, thereby effectively avoiding insufficient municipal pressure caused by water rush during peak periods. The peak or off-peak periods can be set in the control system, providing flexible selection. The following is a detailed description of each device:

[0032] Water replenishment device: The unit replenishes water according to the peak and off-peak time settings of the system. This water replenishment device is generally used during the off-peak period. It closes the No. 2 municipal water inlet butterfly valve 107 and opens the water tank inlet electric valve 106. When the water tank reaches the valve closing level, it closes the water tank inlet electric valve 106.

[0033] Water storage device: Ladder 201 is welded to water tank 204. When water tank 204 needs to be inspected or cleaned, the inside of the tank can be entered through manhole 202 for inspection and cleaning. Remote control float valve 203 is installed at the upper part of water tank 204. It mainly closes the valve of the inlet pipe when the liquid level is high to prevent the replenishment of municipal fluid. When the water tank needs to be cleaned, the drain valve 205 is opened to discharge the stored water and the polluted water from the cleaning to the outside of the tank. When the municipal water replenishment reaches an extremely high level and the water tank inlet electric valve 106 and remote control float valve 203 fail, the excess water can be discharged to the outside of the tank through overflow pipe 206 in a timely manner.

[0034] Disinfection device: During peak periods, water tank 204 is replenished with water. After passing through outlet butterfly valve 301, the fluid enters manual butterfly valve 302 and manual butterfly valve 304 respectively. Manual butterfly valve 302 is always closed. When the sterilizer needs to be replaced, it is manually opened, and manual butterfly valve 304 of the other circuit is closed. After passing through manual butterfly valve 304, the fluid enters sterilizer 305 for disinfection and sterilization. The sterilizer control box 306 can be set to local and remote, manual and automatic states according to actual needs. When replacing sterilizer 305, outlet butterfly valve 301, manual butterfly valve 302, manual butterfly valve 304, and maintenance valve 307 are closed, and outlet drain valve 303 is opened.

[0035] Boosting device: One end of the inlet flexible connector 402 is connected to the No. 2 outlet butterfly valve 401, and the other end is connected to the booster pump 403. The booster pump 403 determines whether to start based on the downstream outlet pressure and controls its frequency and speed. The outlet flexible connector 404 is connected to the check valve 405, and the other end of the check valve is fixed to the No. 3 outlet butterfly valve 406. The pressurized fluid enters the flow stabilization tank 501, thereby achieving the staggered operation of municipal water supply during peak hours and effectively alleviating the situation of insufficient water supply pressure caused by water competition in the municipal pipe network.

[0036] Municipal water supply device: The municipal pipeline 101 and the flange of the Y-type filter 103 are connected by bolts, and the No. 1 municipal water inlet butterfly valve 102 is clamped between them. The flange of the Y-type filter 103 is connected to the backflow preventer 104. After passing through the No. 2 municipal water inlet butterfly valve 107, the fluid enters the flow stabilizing tank 501 along the pipeline 503 for fluid supply. When the pipeline 503 needs to drain, the drain butterfly valve 105 is opened to drain the water.

[0037] Booster Pump Set: Pump set 511 is installed on base 502 and combined with other accessories through main inlet pipe 505 and outlet main pipe 506 to form a booster pump set; the outlet main pipe 506 is connected to the outlet pipe flange and fixed by support 514, with a clamp valve 509 embedded in the middle; after passing through the flow stabilizer tank 501, the fluid flows through butterfly valve 504 into the main inlet pipe 505; according to the configuration of the pump set, it passes through each branch pipe butterfly valve 508 and flexible joint 510 before entering the pump set 511, and the pressurized fluid of the pump set 511 is output to the outlet main pipe 506; at the same time, the pressurized fluid will be supplied to the pressure tank 507 through metal hose 512 for differential pressure supply; when the outlet pressure sensor 513 detects that the outlet pressure is insufficient, it feeds back the pressure signal to the control system, and drives the pump set 511 to perform booster supply after judging and comparing the feedback value and the set value inside the system.

[0038] Pressure relief device: The pressurized fluid is input into pressure relief manual butterfly valve 1 (601) and pressure relief manual butterfly valve 2 (602). Manual butterfly valve 1 (601) is in the closed state for a long time. When the pressure relief device needs to be repaired, it is opened on site to relieve pressure. The fluid after passing through manual butterfly valve 2 (602) enters pressure relief valve 603. When the pressure exceeds a certain value, the valve is opened to relieve pressure. The pressure relief under different conditions finally flows through drain pipe 604 for discharge.

[0039] In summary, this utility model provides a staggered peak water supply system with pressure regulation (no negative pressure), including a box-type pressure regulation (no negative pressure) water supply system and a pipeline pressure regulation (no negative pressure) water supply system. When municipal water supply is at its peak, the pipeline pressure regulation (no negative pressure) water supply system is shut down, and the box-type pressure regulation (no negative pressure) water supply system is turned on to supply water. When municipal water supply is at its low peak, the box-type pressure regulation (no negative pressure) water supply system is shut down, and the pipeline pressure regulation (no negative pressure) water supply system is turned on. By setting different time periods, the system achieves its staggered peak water supply function, thereby reducing the water supply pressure on the municipal pipeline network and avoiding the actual situation of water rush during peak periods.
