Technical Field

[0001] This utility model relates to the technical field of constant pressure water supply devices, specifically a constant pressure water supply device with adaptive pressure adjustment. Background Technology

[0002] A constant-pressure water supply device is an automated device used to maintain stable pressure in a water circulation system. It is widely used in closed-loop systems such as HVAC, heating, and industrial cooling. According to existing technology, such as the constant-pressure water supply device with pressure regulation described in Chinese patent document CN216195086U, the disclosed technical solution, by adding an electrically heated constant-temperature water tank, PLC control, and an outdoor temperature sensor to the existing constant-pressure water supply device, and by improving the structure of the pressure tank, effectively overcomes the defect of pressure drop caused by air cooling in the pressure tank due to decreased ambient temperature. It avoids the influence of environmental factors on the constant-pressure water supply operation, ensuring stable and reliable constant-pressure water supply operation. Furthermore, the entire operation is fully automated, making it highly efficient and convenient.

[0003] According to its publicly available technical solutions, the existing constant pressure water supply device uses a pressure module to detect the water pressure inside the pipeline system. However, in order to continuously detect and automatically replenish water, the water pump needs to be in operation for a long time, resulting in a shortened service life and a short maintenance cycle. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pressure-adaptive, constant-pressure water supply device to solve the problems mentioned in the background section. This invention features a water supply tank on one side of the water pump, which, combined with a one-way valve structure, isolates the pump. Therefore, when the pipeline system requiring constant-pressure water supply is in normal operation, the pump is isolated from the water source and its interior is not filled with water, thus reducing the pump's failure rate and extending its service life. The water flow pressure triggers the pump's on / off state, automatically achieving the purpose of water supply.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a constant pressure water supply device with adaptive pressure regulation, comprising a constant pressure water supply device body, the constant pressure water supply device body comprising a water supply tank, an adaptive regulation component, a pipeline system and a sealing sleeve, a water pump installed at one end of the water supply tank, a pipeline system connected at the other end of the water pump, and a one-way valve installed between the water pump and the pipeline system, an adaptive regulation component built inside the water supply tank, a diversion pipe connected to the surface of the pipeline system, and a water supply pipe and a drainage pipe connected to the side of the water supply tank.

[0006] Furthermore, a solenoid valve is installed on the surface of the drainage pipe, the sealing sleeve is installed at the end of the water supply pipe, a telescopic column is inserted at the end of the diversion pipe, and the adaptive adjustment component 10 is connected to the water pump 2 via an electrical signal to trigger the water pump to start or stop according to the water level or pressure change in the water supply tank 1.

[0007] Furthermore, a sealing membrane is connected to one end of the telescopic column, and a first spring is installed on the inner side of the sealing membrane. The two ends of the first spring are fixedly connected to the inner wall of the diversion pipe and the end of the telescopic column, respectively. A sealing column is integrally formed at the other end of the telescopic column.

[0008] Furthermore, the end of the sealing column is used to be embedded inside the sealing sleeve, and the other end of the sealing membrane is attached to the inner wall of the diversion pipe. The pressure inside the diversion pipe is the same as the overall pressure inside the pipeline system.

[0009] Furthermore, the adaptive adjustment component includes a support plate, a guide plate, a floating plate, and a top plate. A rotating base is inserted into the inner wall of the water replenishment tank. The surface of the rotating base is connected to the guide plate. An end plate is integrally formed at the end of the guide plate, and a drainage hole is provided at the bottom of the end plate.

[0010] Furthermore, a first conductive sheet is installed on the top and bottom of the end plate, water-blocking strips are attached to both sides of the guide plate, and a second spring is installed on the surface of the support plate.

[0011] Furthermore, the top end of the second spring is welded to the bottom surface of the guide plate, a second conductive sheet is attached to the bottom of the top plate, a lower hanging rod is provided on the side of the guide plate, and the top end of the lower hanging rod is connected to the side of the guide plate by a shaft.

[0012] Furthermore, a floating plate is provided at the bottom of the lower hanging rod, and a third conductive sheet is provided at the end of the support plate. The first conductive sheet is used to make contact with the second or third conductive sheet.

[0013] The beneficial effects of this utility model are:

[0014] 1. The pressure adaptive constant pressure water supply device has a water supply tank on one side of the water pump, and with the help of a one-way valve structure, it can isolate the water pump. Therefore, when the pipeline system that needs constant pressure water supply is in normal operation, the water pump is completely idle and will not be filled with water. This reduces the failure rate of the water pump and extends its service life.

[0015] 2. The pressure adaptive regulating constant pressure water replenishment device is equipped with an adaptive regulating component inside the water replenishment tank. When the pressure in the pipeline system drops, the adaptive regulating component can automatically open the top sealing sleeve, allowing water to flow into the water replenishment tank. The water flow pressure then triggers the water pump to switch on and off, automatically achieving the purpose of water replenishment.

[0016] 3. When a slight leak occurs in the sealing sleeve of this pressure adaptive constant pressure water replenishment device, a small amount of water may enter the water replenishment chamber. At this time, the drain hole can directly discharge this small amount of water into the bottom of the water replenishment chamber without directly triggering the water pump to start. At the same time, in conjunction with the float plate, the solenoid valve can be opened to allow the leaking water to be discharged directly, avoiding soaking the water pump.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4This utility model provides the following technical solution: a constant pressure water supply device with adaptive pressure regulation, comprising a constant pressure water supply device body, the constant pressure water supply device body including a water supply tank 1, an adaptive adjustment component 10, a pipeline system 4, and a sealing sleeve 7. A water pump 2 is installed at one end of the water supply tank 1, and the other end of the water pump 2 is connected to the pipeline system 4, with a one-way valve 3 installed between the water pump 2 and the pipeline system 4. The adaptive adjustment component 10 is built inside the water supply tank 1, and a diversion pipe 5 is connected to the surface of the pipeline system 4. A water supply pipe 6 and a drainage pipe 8 are connected to the side of the water supply tank 1. This constant pressure water supply device is used to adaptively regulate the water pressure in the pipeline system 4.

[0024] In use, this invention features a water replenishment chamber 1 on one side of the water pump 2, which, along with a one-way valve 3, isolates the water pump 2. Therefore, when the pipeline system 4 requiring constant pressure water replenishment is in normal operation, the water pump 2 is completely idle and not filled with water, thus reducing the failure rate of the water pump 2 and extending its service life. Specifically, when the pressure at the bottom of the pipeline system 4 decreases, the seal inside the sealing sleeve 7 is automatically released, allowing water from the top of the replenishment pipe 6 to enter the water replenishment chamber 1. This triggers the connection between the first conductive plate 19 and the third conductive plate 23 in the adaptive adjustment component 10, generating an electrical signal that ultimately activates the water pump 2. The water flowing into the water replenishment chamber 1 is then pumped into the pipeline system 4 for pressurization. This design also prevents the water pump 2 from being triggered in the event of leakage inside the sealing sleeve 7.

[0025] In this embodiment, a solenoid valve 9 is installed on the surface of the drainage pipe 8, a sealing sleeve 7 is installed at the end of the water supply pipe 6, and a telescopic column 14 is inserted into the end of the diversion pipe 5. A sealing membrane 13 is connected to one end of the telescopic column 14, and a first spring 12 is installed inside the sealing membrane 13. Both ends of the first spring 12 are fixedly connected to the inner wall of the diversion pipe 5 and the end of the telescopic column 14, respectively. A sealing column 15 is integrally formed at the other end of the telescopic column 14. The end of the sealing column 15 is used to embed into the interior of the sealing sleeve 7, and the other end of the sealing membrane 13 is attached to the inner wall of the diversion pipe 5. The pressure inside the diversion pipe 5 is the same as the overall pressure inside the pipeline system 4. In this embodiment, the stiffness of the first spring 12 is in the range of 5-15 N / mm. When the pressure in the diversion pipe 5 drops by 0.1 MPa, the sealing column 15 is triggered to disengage. An adaptive adjustment component 10 is installed inside the water replenishment tank 1. When the pressure of the pipeline system 4 drops, the adaptive adjustment component 10 automatically opens the top sealing sleeve 7, allowing water to flow into the water replenishment tank 1. The water pressure triggers the switch of the water pump 2, automatically achieving the purpose of water replenishment.

[0026] Specifically, the internal pressure of the diversion pipe 5 is consistent with that of the pipeline system 4. Therefore, when the water pressure inside the pipeline system 4 decreases, the pressure inside the diversion pipe 5 will also decrease. As a result, under the action of the first spring 12, the telescopic column 14 is pulled into the interior of the diversion pipe 5. At this time, the sealing column 15 separates from the interior of the sealing sleeve 7, and the water source at the top of the water supply pipe 6 flows through the sealing column 15 and the sealing sleeve 7 into the water supply chamber 1 at the bottom.

[0027] In this embodiment, the adaptive adjustment component 10 includes a support plate 22, a guide plate 17, a floating plate 26, and a top plate 11. A rotating base 16 is inserted into the inner wall of the water replenishment tank 1. The guide plate 17 is connected to the surface of the rotating base 16. An end plate 18 is integrally formed at the end of the guide plate 17, and a drainage hole 20 is provided at the bottom of the end plate 18. First conductive sheets 19 are installed at the top and bottom of the end plate 18. Water-blocking strips 27 are attached to both sides of the guide plate 17. A second spring 24 is installed on the surface of the support plate 22. The top end of the second spring 24 is welded to the bottom surface of the guide plate 17. A second conductive sheet 21 is attached to the bottom of the top plate 11. A lower hanging rod 25 is provided on the side of the guide plate 17, and the top end of the lower hanging rod 25 is connected to the side of the guide plate 17 by a shaft. A floating plate 26 is provided at the bottom of the lower hanging rod 25, and a third conductive plate 23 is provided at the end of the support plate 22. The first conductive plate 19 at the top of the end plate 18 is used to trigger the opening of the solenoid valve 9 after contacting the second conductive plate 21. The first conductive plate 19 at the bottom of the end plate 18, or the third conductive plate 23, is used to trigger the opening of the water pump 2 after contacting the third conductive plate 23. When a slight leak occurs in the sealing sleeve 7, a small amount of water will enter the interior of the water replenishment tank 1. At this time, the small amount of water can be directly discharged into the bottom of the water replenishment tank 1 through the drainage hole 20, without directly triggering the opening of the water pump 2. At the same time, the floating plate can also be used to control the opening of the solenoid valve 9 to allow the water generated by the leak to be discharged directly, avoiding the soaking effect on the water pump 2.

[0028] Specifically, when the incoming water impacts the bottom guide plate 17, it causes the guide plate 17 to press downwards, compressing the second spring 24. This causes the first conductive sheet 19 and the third conductive sheet 23 to come into contact and generate an electrical signal, which in turn controls the water pump 2 to start. When the sealing performance of the sealing sleeve 7 decreases, water will leak downwards from inside the sealing sleeve 7. At this time, the water flow is weak and cannot press the guide plate 17 downwards until the first conductive sheet 19 and the third conductive sheet 23 come into contact and come into contact. The water will also flow out from the tiny drain hole 20 towards the bottom. As time accumulates, the liquid level gradually rises, eventually lifting the float plate. At this time, the first conductive sheet 19 and the second conductive sheet 21 come into contact and come into contact, generating an electrical signal to control the solenoid valve 9 to open for a period of time, thus draining the water inside the water replenishment tank 1. At the same time, when the sealing sleeve 7 only leaks a small amount, water is drained only through the drain hole 20. Only when the water level exceeds the threshold can the float plate 26 be triggered to move upwards.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
