Description

Technical Field

[0001] This invention relates to the field of building water supply technology, and more particularly to a building pipe network water supply system. Background Technology

[0002] In the past, when urban water plants lacked sufficient capacity, the water supply network was inadequate, and urban water pressure was generally low, rooftop water tanks were installed to supplement water storage at night using residual pressure in the network. Water was then released during peak water usage periods when network pressure dropped, alleviating the problem of insufficient water supply and effectively resolving the supply-demand imbalance, thus stabilizing water pressure. However, with the increasing number and height of buildings, the rooftop water tank solution is no longer sufficient to meet the water supply needs of modern high-rise buildings. The current common practice is to add a parallel pressure tank after the variable frequency water pump, using the pressure tank to supplement the water supply network, thus replacing the rooftop water tank solution.

[0003] However, with the increasing number of high-rise buildings in cities, their accumulated waste energy consumption has reached an alarming amount. Moreover, with the increase in high-rise and even super high-rise buildings, the pressure on water supply networks has further intensified. Therefore, it is no longer sufficient to meet the needs of the entire network system to install only one pressure tank.

[0004] Therefore, there is an urgent need for a building water supply system to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a building pipe network water supply system that reduces pump head, reduces pump flow, saves energy and reduces emissions, enhances water replenishment effect, and improves water replenishment efficiency.

[0056] In order to reduce the pump head, reduce the pump flow rate, save energy and reduce emissions, enhance the water supply effect, and improve the water supply efficiency, this embodiment provides a building pipe network water supply system.

[0057] Example 1

[0058] like Figures 1 to 11As shown, the building's water supply system includes a high-rise water supply network 1, a non-high-rise water supply network 2, a water pump 3, and an auxiliary flow regulating device 4. The high-rise water supply network 1 includes a high-rise water supply pipeline 11 and a high-rise flow regulating device 12. The high-rise flow regulating device 12 is connected in parallel with the high-rise water supply pipeline 11. The high-rise water supply pipeline 11 supplies water to multiple high-rise water outlets 13. The non-high-rise water supply network 2 is connected in parallel with the high-rise water supply network 1. The non-high-rise water supply network 2 includes a non-high-rise water supply pipeline 21 and a non-high-rise flow regulating device 22. The non-high-rise flow regulating device 22 is connected in parallel with the non-high-rise water supply pipeline 21. Water supply pipeline 21 is used to supply water to multiple low-zone water terminals 23. Water supply pump 3 is used to supply water to high-zone water supply pipeline 11 and non-high-zone water supply pipeline 21. Auxiliary flow regulating device 4 includes flow regulating box 41 and flow regulating pipe 42. One of flow regulating box 41 or flow regulating pipe 42 is connected in series in high-zone water supply pipeline 11. Alternatively, both flow regulating box 41 and flow regulating pipe 42 can be connected in series in high-zone water supply pipeline 11. One of flow regulating box 41 or flow regulating pipe 42 is connected in series in non-high-zone water supply pipeline 21. Alternatively, both flow regulating box 41 and flow regulating pipe 42 can be connected in series in non-high-zone water supply pipeline 21.

[0059] By connecting a high-zone flow regulating device 12 in parallel in the high-zone water supply network 1 and a non-high-zone flow regulating device 22 in parallel in the non-high-zone water supply network 2, the high-zone water supply network 1 and the non-high-zone water supply network 2 can be managed separately, allowing for more precise water replenishment. Furthermore, by connecting one of the flow regulating boxes 41 or flow regulating pipes 42 in the auxiliary flow regulating device 4 in series in the high-zone water supply pipeline 11 and the non-high-zone water supply pipeline 21, or by connecting both in series, the water replenishment efficiency in the building network can be further improved, enhancing the water replenishment effect and thus meeting the increasingly severe water supply pressure. By alleviating the water supply pressure, the lifespan of pipes, pumps, and valves in the water supply network is extended. Moreover, the auxiliary flow regulating device 4 not only reduces the pump head but also reduces energy consumption, allowing a single water supply pump 3 to meet the water supply demand, thus saving costs.

[0060] In this embodiment, as Figure 12 As shown, the non-high-altitude water supply network 21 also includes a non-high-altitude municipal water supply pipeline 8. The non-high-altitude municipal water supply pipeline 8 is connected in parallel with the non-high-altitude water supply pipeline 21 and the high-altitude water supply pipeline 11. Unlike the non-high-altitude water supply pipeline 21, the non-high-altitude municipal water supply pipeline 8 does not have a water supply pump 3. It can directly supply water to the low-altitude water supply end 23 through the municipal water supply system, thereby cooperating with the non-high-altitude water supply pipeline 21 to further reduce the energy consumption of the water supply pump 3. In order for the non-high-altitude municipal water supply pipeline 8 to better supply water to the low-altitude water supply end 23, a municipal diversion device 9 is also provided in the non-high-altitude municipal water supply pipeline 8, as well as one of the diversion box 41 or diversion pipe 42 connected in series. Alternatively, both the diversion box 41 and the diversion pipe 42 can be connected in series.

[0061] like Figures 1 to 3 As shown, in this embodiment, the water supply pump 3 is a power frequency pump. Compared with traditional high-rise building water supply technology such as residential variable frequency water supply technology, the power frequency pump used in this embodiment can eliminate the power loss of the frequency converter. Of course, a variable frequency pump can also be used in this embodiment. In this case, the specifications of the variable frequency pump can be reduced, the loss caused by power fluctuation can be reduced, and it is more energy-efficient. The water supply pump 3 is controlled to start and stop by the pressure switch 5. In addition, in order to prevent water backflow, a first check valve 6 is provided between the water supply pump 3 and the high-zone flow regulating device 12, and a second check valve 7 is provided between the water supply pump 3 and the non-high-zone flow regulating device 22. In this embodiment, both the high-zone flow regulating device 12 and the non-high-zone flow regulating device 22 are pressure tanks with water replenishment and pressure regulation functions.

[0062] Optionally, such as Figure 1 As shown, the non-high-zone water supply network 2 includes multiple low-zone water supply networks. Each low-zone water supply network supplies water to its respective multiple low-zone water terminals 23. The non-high-zone water supply pipeline 21 includes a main non-high-zone water supply pipeline 211 and multiple parallel non-high-zone water supply secondary pipelines 212. Each of the multiple non-high-zone water supply secondary pipelines 212 is connected in series with either a flow regulating box 41 or a flow regulating pipe 42. Alternatively, both the flow regulating box 41 and the flow regulating pipe 42 can be connected in series in multiple non-high-zone water supply secondary pipelines 212. The non-high-zone water supply secondary pipelines 212 are used to supply water to the corresponding low-zone water terminals 23. By further subdividing the non-high-zone water supply network 2 and connecting the flow regulating pipe 42 or the flow regulating box 41 in series in each non-high-zone water supply secondary pipeline 212, water replenishment to each low-zone water supply network can be performed more accurately and efficiently.

[0063] Optionally, such as Figures 4 to 8 As shown, the regulating pipe 42 includes an inlet pipe 421, an outlet pipe 422, and a replenishment pipe 423. The two ends of the replenishment pipe 423 are connected to the inlet pipe 421 and the outlet pipe 422, respectively. The inner diameter of the replenishment pipe 423 is larger than the inner diameters of both the inlet pipe 421 and the outlet pipe 422. A pressure regulating port for balancing the internal air pressure of the replenishment pipe 423 is also provided. By setting a replenishment pipe 423 with an inner diameter larger than both the inlet pipe 421 and the outlet pipe 422 between them, a certain amount of water can be stored in the replenishment pipe 423. When the water consumption is relatively low, the water temporarily stored in the replenishment pipe 423 is used to supply water to the low-area water consumption end 23 and the high-area water consumption end 13. This eliminates the need for the water supply pump 3 to start when water consumption is low, thus avoiding frequent start-stop cycles, reducing energy consumption, and extending the service life of the water supply pump 3. Furthermore, when water consumption is high, the water supply pump 3, the water supply pipe 423, and the high-zone flow regulating device 12 or the low-zone flow regulating device supply water together, reducing the flow rate of the water supply pump 3 during peak water consumption. This allows for the selection of a smaller power water supply pump 3, thereby saving costs and reducing construction costs.

[0064] In this embodiment, the diversion pipe 42 includes multiple inlet pipes 421. Under the condition of meeting the water supply demand, multiple low-zone water supply networks can be connected to the same water supply pipe 423 through multiple inlet pipes 421. Water supply and diversion can be carried out for multiple low-zone water supply networks through the same water supply pipe 423, thereby saving manufacturing costs. The length of the water supply pipe 423 can be long or short, and the shape of the water supply pipe 423 can be a circular structure, a square structure, a straight structure, or a curved structure with a hollow interior. Furthermore, the water supply pipe 423 can be installed vertically, at an angle, or horizontally. In summary, the length, shape, and installation method of the water supply pipe 423 are not limited as long as they meet the functions of this application, and can be modified according to the site requirements. Further details are omitted here.

[0065] Furthermore, such as Figures 5 to 8 As shown, the flow regulating pipe 42 also includes a pressure regulating pipe valve 424. The pressure regulating pipe valve 424 includes an exhaust pipe 4241 and an intake pipe 4242. One end of the intake pipe 4242 is connected to the exhaust pipe 4241, and the other end of the intake pipe 4242 is connected to the outside. One end of the exhaust pipe 4241 is connected to the pressure regulating port, and the other end of the exhaust pipe 4241 is connected to the outside. An exhaust valve 4243 is provided inside the exhaust pipe 4241. The exhaust valve 4243 is used to control the connection between the exhaust pipe 4241 and the outside. An intake valve 4244 is provided inside the intake pipe 4242. The intake valve 4244 is used to control the connection between the intake pipe 4242 and the outside. By designing a pressure regulating valve 424, the air pressure inside the flow regulating pipe 42 can be balanced by automatically opening or closing the air regulating valve 4243 and the air intake valve 4244 when water enters or exits. Furthermore, by setting the flow regulating valve 424, external dust and impurities can be prevented from entering the pipe network system.

[0066] Optionally, such as Figure 5 , Figure 7As shown, a water-stop valve 4245 is also provided inside the exhaust pipe 4241. A first annular baffle 42411 is provided at the water-stop valve 4245. The water-stop valve 4245 includes a water-stop upper cover 42451, a water-stop lower cover 42452, a water-stop connecting rod 42453, a first elastic element 42454, and a float 42455. The water-stop upper cover 42451 and the water-stop lower cover 42452 are respectively connected to the two ends of the water-stop connecting rod 42453 and are respectively located on both sides of the first annular baffle 42411. The water-stop connecting rod 42453 is slidably inserted in the first annular baffle 42411. The float 42455 is connected to the side of the water-stop lower cover 42452 away from the water-stop upper cover 42451. The first elastic element 42454 is sandwiched between the water-stop upper cover 42451 and the first annular baffle 42411. By setting a water stop valve 4245, when water is injected into the flow regulating pipe 42, as the water level rises, the water gradually enters the vent pipe 4241. At this time, the buoyancy of the water will drive the float 42455 to gradually rise, so that the water stop cover 42452 abuts against the first annular baffle 42411, thereby sealing the vent pipe 4241 and preventing water from flowing out of the vent pipe 4241.

[0067] In this embodiment, the float 42455 and the lower waterproof cover 42452 are connected together by a rigid rod. To ensure that the buoyancy of the float 42455 can drive the upper waterproof cover 42451, the lower waterproof cover 42452, and the waterproof connecting rod 42453 to float upward as a whole, the upper waterproof cover 42451, the lower waterproof cover 42452, and the waterproof connecting rod 42453 are all made of lightweight materials. For example, the first elastic element 42454 is a spring.

[0068] Optionally, such as Figure 5 , Figure 6 As shown, the exhaust pipe 4241 is provided with a second annular baffle 42412 at the exhaust valve 4243. The exhaust valve 4243 includes an exhaust upper cover 42431, an exhaust lower cover 42432 and an exhaust connecting rod 42433. The exhaust upper cover 42431 and the exhaust lower cover 42432 are respectively connected to the two ends of the exhaust connecting rod 42433 and are respectively located on both sides of the second annular baffle 42412. The exhaust connecting rod 42433 is slidably inserted into the second annular baffle 42412. By using an exhaust top cover 42431 and an exhaust bottom cover 42432 connected to both ends of an exhaust connecting rod 42433 as an exhaust valve 4243, during non-exhaust operation, the structure consisting of the exhaust top cover 42431, the exhaust bottom cover 42432, and the exhaust connecting rod 42433 falls onto the second annular baffle 42412 under the action of gravity. The exhaust top cover 42431 abuts against the second annular baffle 42412, thereby sealing the exhaust pipe 4241 when the exhaust top cover 42431 is not in the exhaust operation state.

[0069] In this embodiment, the exhaust upper cover 42431, exhaust lower cover 42432 and exhaust connecting rod 42433 that make up the exhaust valve 4243 are all made of lightweight materials, thereby ensuring that when exhausting, the discharged gas can push the exhaust lower cover 42432, so that the exhaust upper cover 42431 separates from the second annular baffle 42412, so that the gas can be discharged smoothly.

[0070] Optionally, such as Figure 5 , Figure 8 As shown, the suction pipe 4242 is provided with a third annular baffle 42421 at the suction valve 4244. The suction valve 4244 includes an upper suction cover 42441, a lower suction cover 42442, and a suction connecting rod 42443. The upper suction cover 42441 and the lower suction cover 42442 are respectively connected to the two ends of the suction connecting rod 42443 and are respectively located on both sides of the third annular baffle 42421. The suction connecting rod 42443 is slidably inserted in the third annular baffle 42421. By using an upper suction cover 42441 and a lower suction cover 42442 connected to both ends of a suction connecting rod 42443 as suction valves 4244, during non-suction operation, the structure consisting of the upper suction cover 42441, the lower suction cover 42442, and the suction connecting rod 42443 falls onto the third annular baffle 42421 under the action of gravity. The upper suction cover 42441 abuts against the third annular baffle 42421, thereby sealing the suction pipe 4242 when the upper suction cover 42441 is not in the suction operation state.

[0071] In this embodiment, the upper suction cover 42441, the lower suction cover 42442, and the suction connecting rod 42443 that make up the suction valve 4244 are all made of lightweight materials, thereby ensuring that when suction is performed, the external gas can push the lower suction cover 42442, causing the upper suction cover 42441 to separate from the third annular baffle 42421, so that the gas can smoothly enter the intake pipe.

[0072] Optionally, such as Figures 9 to 11As shown, the flow regulating box 41 includes a main box 411 and a secondary water storage box 412 connected to the main box 411. The main box 411 is connected in series in the high-zone water supply pipeline 11 or the non-high-zone secondary water supply pipeline 212. The secondary water storage box 412 is equipped with a flexible water storage structure. By setting the flow regulating box 41, a certain amount of water is stored in the flexible water storage structure in the secondary water storage box 412. When the water consumption is relatively small, water is supplied to the low-zone water end 23 and the high-zone water end 13 by utilizing the water temporarily stored in the flexible water storage structure. This eliminates the need for the water supply pump 3 to start when the water consumption is small, thereby avoiding frequent start-stop of the water supply pump 3, reducing energy consumption, and increasing the service life of the water supply pump 3. Furthermore, since the water supply pump 3, the secondary water storage box 412, and the high-zone flow regulating device 12 or the non-high-zone flow regulating device 22 supply water together when the water consumption is large, the flow rate of the water supply pump 3 during peak water consumption is reduced. This allows for the selection of a smaller power water supply pump 3, thereby saving costs and reducing construction costs.

[0073] In this embodiment, the connection between the main tank 411 and the secondary water storage tank 412 can be a box structure or a cylindrical tank structure, etc., and the volume of the connection between the main tank 411 and the secondary water storage tank 412 can be designed according to requirements. In summary, the shape and volume of the connection between the main tank 411 and the secondary water storage tank 412 are not limited as long as they meet the functions of this application, and can be modified according to the site requirements. Further details will not be provided here.

[0074] Optionally, such as Figure 9 As shown, the elastic water storage structure includes a base plate 4121, a second elastic element 4122, and an elastic membrane 4123. The second elastic element 4122 is sandwiched between the base plate 4121 and the bottom of the secondary water storage tank 412. One end of the elastic membrane 4123 is connected to the base plate 4121, and the other end is connected to the junction of the main tank 411 and the secondary water storage tank 412. The water storage cavity formed by the elastic membrane 4123 and the base plate 4121 is connected to the main tank 411. By utilizing the elasticity of the elastic membrane 4123, the elastic membrane 4123 expands under pressure when storing water, while the second elastic element 4122 is compressed. When water needs to be replenished using the elastic water storage structure, the water in the elastic water storage structure is discharged under the elastic force of the second elastic element 4122 and the elastic membrane 4123, thereby realizing water replenishment using the elastic water storage structure.

[0075] In this embodiment, the second elastic element 4122 is a spring. When the elastic water storage structure stores water, the spring is compressed. When the elastic water storage structure is replenished with water, the spring pushes the bottom plate 4121 to discharge the water through its own elastic force. The elastic membrane 4123 can be made of any elastic material. For example, rubber can be used to make the elastic membrane 4123. The elastic membrane 4123 can be connected to the bottom plate 4121 through structural connections, or it can be connected to the bottom plate 4121 by means of adhesion, etc. The specific connection method is a conventional method and will not be described in detail here. Furthermore, due to the function of the second elastic element 4122, the internal volume of the elastic water storage structure can also be changed. Therefore, the elastic membrane 4123 can also be made of a flexible material. Its shape and size can be made according to actual needs and will not be described in detail here.

[0076] Optionally, such as Figure 10 As shown, the flow regulating box 41 includes multiple secondary water storage tanks 412, distributed circumferentially along the connection to the main box 411. By adding multiple secondary water storage tanks 412, the water storage capacity of the flow regulating box 41 is increased, thereby better realizing the water replenishment function. In this embodiment, four secondary water storage tanks 412 are evenly distributed at 90° along the axial direction connecting to the main box 411. In other embodiments, the number and arrangement angle of the secondary water storage tanks 412 can be modified according to actual needs, and are not limited to the above-mentioned number, distribution angle, or whether they are evenly distributed.

[0077] In actual operation, water from the municipal water supply system is first pumped by water pump 3 to the high-altitude water supply network 1 and the non-high-altitude water supply network 2. Water in the high-altitude water supply network 1 flows along the high-altitude water supply pipeline 11 to multiple high-altitude water outlets 13 for supply. A portion of this water is stored in the high-altitude flow regulating device 12 (i.e., a pressure tank) and the auxiliary flow regulating device 4 (i.e., a flow regulating pipe 42 or a flow regulating box 41). When water consumption is low, water pump 3 will not start, and the high-altitude flow regulating device 12 will supply water to the high-altitude water outlets 13. Due to the unpredictable nature of water consumption, it may suddenly increase; in this case, water pump 3... In cases where water supply cannot be provided in a timely manner, the auxiliary flow regulating device 4 in the high-zone water supply pipeline 11 connected in series will assist the high-zone flow regulating device 12 in supplying water. In this embodiment, the auxiliary flow regulating device 4 connected in series in the high-zone water supply pipeline 11 is a flow regulating box 41. When the flow regulating box 41 is needed for auxiliary water supply, since the pressure fed back from the main flow regulating box to the secondary water storage box 412 is less than the elastic force of the second elastic element 4122 and the elastic membrane 4123, the second elastic element 4122 and the elastic membrane 4123 begin to return to their original shape and squeeze the water in the secondary water storage box 412 into the main flow regulating box, and supply water to the high-zone water terminal 13.

[0078] Water delivered to the non-high-zone water supply network 2 flows along the main non-high-zone water supply pipeline 211 to multiple parallel non-high-zone secondary water supply pipelines 212, supplying water to multiple low-zone water-using terminals 23 in the multiple low-zone water supply networks. A portion of this water is stored in the non-high-zone flow regulating device 22 (i.e., a pressure tank) connected in parallel with the main non-high-zone water supply pipeline 211, while another portion flows into the auxiliary flow regulating device 4 (i.e., the flow regulating pipe 42 or the flow regulating box 41) for storage. When water consumption is low, the water supply pump 3 will not start, and the non-high-zone flow regulating device 22 will supply water to the low-zone water-using terminals 23. Due to the unpredictability of water consumption, it may suddenly increase; in this case, the water supply... If pump 3 is unable to supply water in a timely manner, the auxiliary flow regulating device 4 in the non-high zone water supply secondary pipeline 212 connected in series will assist the non-high zone flow regulating device 22 in supplying water. In this embodiment, the auxiliary flow regulating device 4 connected in series in the non-high zone water supply secondary pipeline 212 is a flow regulating pipe 42. Since the inner diameter of the water supply pipe 423 of the flow regulating pipe 42 is larger than the inner diameter of the inlet pipe 421 and the inner diameter of the outlet pipe 422, a certain amount of water is stored in the water supply pipe 423. When the flow regulating pipe 42 is needed to assist in water supply, the water stored in the water supply pipe 423 will supply water to the low zone water end 23 together with the non-high zone flow regulating device 22 to meet the water demand of the low zone water end 23.

[0079] The flow regulating pipe 42 valve, which is connected to the pressure regulating port of the water supply pipe 423, has four working states: initial state, first stage exhaust state, second stage exhaust state, and intake state.

[0080] Initial state: The stop valve 4245 is normally open. At this time, the first elastic element 42454 of the stop valve 4245 is in a compressed state under the action of the gravity of the upper stop cover 42451, the lower stop cover 42452, the stop connecting rod 42453 and the float 42455. The exhaust valve 4243 is closed and the intake valve 4244 is closed.

[0081] First stage of venting: When water is injected, in order to ensure air pressure balance, it is necessary to vent outward. At this time, the gas passes through the water stop valve 4245, which lifts the lower vent cover 42432, causing the upper vent cover 42431 to separate from the first annular baffle 42411, so that the gas can pass through and venting is achieved. At this time, the air intake valve 4244 is closed.

[0082] Second stage of venting: After water has been injected for a period of time, water enters through the vent pipe 4241. At this time, the float 42455 moves upward under the action of water buoyancy. At this time, the gravity of the water-stopping upper cover 42451, water-stopping lower cover 42452, water-stopping connecting rod 42453 and float 42455 is eliminated. The first elastic element 42454 resets and assists the float 42455 in moving the water-stopping lower cover 42452 closer to the first circular baffle 42411 until the water-stopping lower cover 42452 closes the first circular baffle 42411, thereby sealing the drain pipe and preventing water from flowing out of the vent pipe 4241. At this time, the gas is no longer discharged. The venting lower cover 42432 of the vent valve 4243 loses the gas propulsion and falls under the action of gravity. At this time, the venting upper cover 42431 closes the second circular baffle 42412, the vent valve 4243 is closed, and the suction valve 4244 is closed.

[0083] During the air intake phase: When supplying water, in order to ensure air pressure balance, it is necessary to draw in external air. At this time, the float 42455 loses the buoyancy of the water. Under the weight of the upper water stop cover 42451, the lower water stop cover 42452, the water stop connecting rod 42453, and the float 42455, the first elastic element 42454 is compressed, so that the elastic force of the first elastic element 42454 is equal to the weight of the upper water stop cover 42451, the lower water stop cover 42452, the water stop connecting rod 42453, and the float 42455 and the contraction stops. The water stop valve 4245 opens. At this time, the upper part of the air intake cover 42441 is in a negative pressure state. The external air pushes the lower air intake cover 42442, causing the upper air intake cover 42441 to separate from the third annular baffle 42421. The external air enters the air intake pipe 4242, thereby balancing the air pressure in the water supply pipe 423.

[0084] Example 2

[0085] Unlike Embodiment 1, in Embodiment 1, the high-zone water supply pipeline 11 and the non-high-zone water supply pipeline 21 are two parallel pipelines, and the water supply pump 3 is located at the connection of the two pipelines. In this embodiment, the high-zone water supply pipeline 11 and the non-high-zone water supply pipeline 21 can also be different branches on a main water supply pipeline 100, and the water supply pump 3 only needs to supply water to the main water supply pipeline 100.

[0086] In this embodiment, as Figure 13As shown, the pipeline system includes a main water supply pipeline 100, a high-zone branch pipeline 200, and multiple non-high-zone branch pipelines 300. The high-zone branch pipeline 200 and the multiple non-high-zone branch pipelines 300 are connected in parallel to each other in the main water supply pipeline 100. A water supply pump 3 is used to supply water to the main water supply pipeline 100. A high-zone water replenishment branch pipeline 400 and a non-high-zone water replenishment branch pipeline 500 are also provided on the main water supply pipeline 100. A high-zone flow regulating device 12 for replenishing water to the high-zone branch pipeline 200 is installed in the high-zone water replenishment branch pipeline 400. In the non-high-zone water replenishment branch pipeline... The pipeline 500 is equipped with a non-high zone flow regulating device 22 for replenishing water to the non-high zone branch pipeline 300, and a one-way valve 600 is installed in the high zone water replenishment branch pipeline 400, so as to ensure that the high zone flow regulating device 12 is only responsible for replenishing water to the high zone branch pipeline 200. One of the flow regulating box 41 or flow regulating pipe 42 is connected in series in the main water supply pipeline 100, the high zone branch pipeline 200 and the non-high zone branch pipeline 300. Alternatively, both the flow regulating box 41 and the flow regulating pipe 42 can be connected in series to cooperate with the high zone flow regulating device 12 and the non-high zone flow regulating device 22 for water supply.

[0087] Similar to Embodiment 1, in this embodiment, the water supply pump 3 is also controlled by the pressure switch 5, and a non-high-zone municipal water supply pipeline 8 is also provided in parallel with the main water supply pipeline 100. Unlike the main water supply pipeline 100, the non-high-zone municipal water supply pipeline 8 does not have a water supply pump 3. It can directly supply water to the low-zone water end 23 through the municipal water supply system, thereby cooperating with the non-high-zone branch pipeline 300 to further reduce the energy consumption of the water supply pump 3. In order for the non-high-zone municipal water supply pipeline 8 to better supply water to the low-zone water end 23, one of the flow regulating box 41 or the flow regulating pipe 42 is connected in series in the non-high-zone municipal water supply pipeline 8. Alternatively, both the flow regulating box 41 and the flow regulating pipe 42 can be connected in series.
