[0001] This utility model relates to the field of water pipe pressure regulation technology, specifically a pressure regulating device for tap water pipe networks. Background Technology

[0002] In modern urban water supply systems, the stable operation of the water supply network is crucial. Due to factors such as the wide distribution of users, diverse water demands, and complex network layout, water pressure fluctuations occur frequently. Excessively high water pressure can easily lead to pipe rupture and damage, while excessively low water pressure cannot meet the normal water demand of users. Therefore, we need to propose a water supply network pressure regulating device. Utility Model Content

[0003] The purpose of this utility model is to provide a water supply network pressure regulating device that can provide water pressure adjustment function, and can prevent the pipe from breaking due to excessively high water pressure or failing to meet the normal water demand of users when water pressure fluctuates, so as to solve the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A water supply network pressure regulating device includes a bottom 1, a bracket 6 fixedly installed on the top of the bottom 1, a main conveying pipe 7 fixedly installed on the bracket 6, a plurality of conveying branch pipes 12 connected to the main conveying pipe 7, and a water pressure sensor 13 for pressure detection installed on each of the plurality of conveying branch pipes 12.

[0023] Each of the multiple sets of conveying branch pipes 12 is connected to a first pressure relief pipe 15 for pressure relief, and a second pressure relief valve 16 for controlling the flow rate of the pressure relief water is installed on the first pressure relief pipe 15;

[0024] Both ends of the main conveying pipe 7 are connected to connecting pipes 19, and the connecting pipes 19 are connected to energy storage tanks 17 for stabilizing the pressure inside the conveying branch pipes 12.

[0025] It should be noted that the delivery branch pipe 12 is used to connect to the water pipes in the user's home and deliver water to the user's home. The water pressure sensor 13 can detect the pressure inside the delivery branch pipe 12 to prevent the delivery branch pipe 12 from breaking due to excessive pressure, while ensuring normal water use for high-rise users.

[0026] Once the pressure inside the delivery branch pipe 12 exceeds the threshold, a feedback signal is immediately sent to open the second pressure relief valve 16, realizing automatic overpressure diversion, releasing excessive water pressure in time, greatly reducing the risk of pipe rupture and bursting due to excessive pressure, extending the service life of the pipeline network, and reducing maintenance costs and the frequency of water outage repairs.

[0027] When delivering water to users, some tap water can enter the storage tank 17 through the connecting pipe 19 for storage. The water stored in the storage tank 17 can be transported to the delivery branch pipe 12 through the connecting pipe 19 and the main delivery pipe 7 when users on lower floors use a small amount of water. This stabilizes the pressure in the delivery branch pipe 12, meets the normal water demand of users, reduces the frequent start and stop of the water pump, reduces motor wear, extends equipment life, and reduces energy consumption.

[0028] In an optional embodiment: a water storage tank 2, a pressureless water tank 3 and a first water pump 4 are fixedly installed on the top of the bottom 1. The first water pump 4 is located between the water storage tank 2 and the pressureless water tank 3. The inlet and outlet of the first water pump 4 are both connected to a first extraction pipe 5. The first extraction pipe 5 at the inlet of the first water pump 4 is connected to the water storage tank 2, and the first extraction pipe 5 at the outlet of the first water pump 4 is connected to the pressureless water tank 3.

[0029] It should be noted that the storage tank 2 is used for municipal tap water storage. With the first water pump 4 and the first extraction pipe 5, tap water can be drawn from the storage tank 2 and transported to the unpressurized water tank 3 when the water level in the unpressurized water tank 3 is low.

[0030] In an optional embodiment: a second water pump 8 is fixedly installed on the top of the bottom 1. The inlet and outlet of the second water pump 8 are both connected to a second extraction pipe 9. The second extraction pipe 9 at the inlet of the second water pump 8 is connected to the pressureless water tank 3. The second extraction pipe 9 at the outlet of the second water pump 8 is connected to the main delivery pipe 7. A first solenoid valve 10 and a filter 11 are provided on the second extraction pipe 9 at the outlet of the second water pump 8.

[0031] It should be noted that, through the second water pump 8 and the second extraction pipe 9, water in the unpressurized water tank 3 can be extracted and transported to the main delivery pipe 7. The pressure of the tap water delivered to the main delivery pipe 7 can be controlled by the first solenoid valve 10 to prevent the pressure in the main delivery pipe 7 from being too high and to achieve automatic adjustment. When the pressure is detected to be too high, the solenoid valve will be automatically reduced or closed to avoid pressure fluctuations in the pipeline network. The filter 11 can filter and remove impurities from the user's water.

[0032] A check valve is also installed on the second extraction pipe 9 to prevent high-pressure water from flowing back into the unpressurized water tank 3.

[0033] In an optional embodiment: a drain pipe 27 is connected to the storage tank 2, and the other end of the drain pipe 27 is connected to the unpressurized water tank 3. A fourth solenoid valve 28 is provided on the unpressurized water tank 3. A water injection pipe 23 for water injection is connected to the storage tank 2. A third solenoid valve 24 is provided on the water injection pipe 23. A second water level sensor 25 is installed on the storage tank 2, and a third water level sensor 26 is installed on the unpressurized water tank 3.

[0034] It should be noted that the water level in the storage tank 2 or the unpressurized water tank 3 can be detected by the second water level sensor 25 and the third water level sensor 26. When water is injected into the storage tank 2 through the water injection pipe 23, if the water level in the unpressurized water tank 3 is not full, the fourth solenoid valve 28 is activated, so that the tap water in the storage tank 2 can flow directly to the unpressurized water tank 3 through the drain pipe 27. This eliminates the need to frequently start and stop the first water pump 4, reduces motor wear, extends equipment life, and reduces energy consumption.

[0035] In an optional embodiment: a water supply pipe 20 is connected to the unpressurized water tank 3, one end of the water supply pipe 20 is connected to a connecting pipe 21, the connecting pipe 21 is connected to two sets of energy storage tanks 17, a second solenoid valve 22 is provided on the water supply pipe 20, and a first water level sensor 18 is installed in the energy storage tank 17.

[0036] It should be noted that, through the setting of the water supply pipe 20, the first water level sensor 18 can detect the water level in the energy storage tank 17. When water is injected into the unpressurized water tank 3, if the water level in the energy storage tank 17 is too low and no replenishment is made, the second solenoid valve 22 is opened, so that the tap water in the unpressurized water tank 3 can be transported to the unpressurized water tank 3 through the water supply pipe 20 to replenish the tap water in the unpressurized water tank 3.

[0037] In an optional embodiment: the bottom of the unpressurized water tank 3 is connected to a second pressure relief pipe 29 for pressure relief, and a first pressure relief valve 14 is installed on the second pressure relief pipe 29.

[0038] It should be noted that, through the cooperation of the first pressure relief valve 14 and the second pressure relief pipe 29, the first pressure relief valve 14 can be opened when the water level in the unpressurized water tank 3 is too high, so that the water in the unpressurized water tank 3 can be discharged through the second pressure relief pipe 29. The first water pump 4, the second water pump 8, the first solenoid valve 10, the water pressure sensor 13, the first pressure relief valve 14, the second pressure relief valve 16, the first water level sensor 18, the second solenoid valve 22, the third solenoid valve 24, the second water level sensor 25, the third water level sensor 26, and the fourth solenoid valve 28 are all electrically connected to the control system. The control system can be set as a frequency conversion intelligent control cabinet. Its control circuit and connection are common knowledge in the field. Furthermore, this application document is mainly used to protect the structure and shape and their combination, so this application document will not explain the control method and circuit connection in detail.

[0039] The usage process of this utility model is as follows: The water pressure sensor 13 monitors the pressure inside the delivery branch pipe 12 in real time. When the lower-level users use a small amount of water, there is no need to start the second water pump 8. When the water pressure in the delivery branch pipe 12 is insufficient, the storage tank 17 releases the stored water to replenish it. The water in the storage tank 17 can be delivered to the delivery branch pipe 12 in real time through the connecting pipe 19 and the main delivery pipe 7, stabilizing the pressure inside the delivery branch pipe 12, so that the water pressure in the pipeline network is always maintained within a reasonable range, ensuring stable water use for users, meeting the normal water use needs of users, reducing the frequent start and stop of the water pump, reducing motor wear, extending equipment life, and reducing energy consumption.

[0040] If users on both high-rise and low-rise floors use water simultaneously, the water pressure sensor 13 monitors the pressure in the delivery branch pipe 12 in real time. The storage tank 17 releases stored water to replenish the main delivery pipe 7 and the delivery branch pipe 12 in real time, stabilizing the pressure in the delivery branch pipe 12. When the water pressure in the delivery branch pipe 12 is insufficient, the water pressure sensor 13 sends the water pressure reading to the control system, which starts the second water pump 8. The second water pump 8 draws water from the unpressurized water tank 3 through the second extraction pipe 9 and delivers it to the main delivery pipe 7. The water delivered to the main delivery pipe 7 can then be transported through the delivery branch pipes. Water is supplied to users' homes via pipe 12. Water pressure sensor 13 monitors the pressure inside pipe 12 in real time. If the pressure inside pipe 12 is too high, the second pressure relief valve 16 is opened, allowing water in pipe 12 to be diverted and relieved through the first pressure relief pipe 15. This achieves automatic overpressure diversion, preventing the lower-level pipe 12 from rupturing due to excessive pressure, while ensuring normal water supply for upper-level users. By controlling the opening range of the second pressure relief valve 16, the pressure in the lower-level pipe 12 is controlled, preventing the pressure inside pipe 12 from being too low or too high.
