Description

Technical Field

[0001] This utility model relates to the field of water supply device technology, specifically to an automatic pressure-stabilizing centralized water supply device. Background Technology

[0002] In modern building water supply, industrial production water and residential water use, centralized water supply systems are the core facilities for ensuring the stable delivery of water resources. Their operational stability and reliability are directly related to water safety and efficiency. With the acceleration of urbanization and the expansion of industrial production scale, users have put forward higher requirements for the pressure stability, water supply continuity and energy consumption control of water supply systems. Traditional centralized water supply devices have gradually exposed many technical shortcomings and are unable to meet the needs of the current complex water use scenarios.

[0003] Traditional centralized water supply systems often employ a single pump for direct water supply or a simple tank-pump combination. These systems commonly suffer from significant pressure fluctuations during operation. During peak water usage periods, when user demand surges, the system's supply cannot keep up, leading to a sharp drop in network pressure, reduced flow, and water outages for high-rise residents. Conversely, during off-peak periods, when water consumption decreases drastically, network pressure rises abnormally, causing additional wear and tear on pipes and valves, shortening equipment lifespan, and potentially leading to pipe ruptures and leaks. Furthermore, some older systems lack effective pressure regulation mechanisms. Even when equipped with simple pressure control elements, manual adjustment is often necessary, resulting in low precision, slow response, and difficulty in achieving real-time dynamic pressure stabilization, further exacerbating the instability of the water supply pressure.

[0004] Therefore, this utility model proposes an automatic pressure-stabilizing centralized water supply device to solve the above-mentioned problems. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is: An automatic pressure-stabilizing centralized water supply device includes a support base on which a pressure-stabilizing tank is connected. A pump mounting bracket is provided on one side of the upper surface of the support base, and a pressure-stabilizing pump is fixedly connected to the pump mounting bracket by bolts.

A piston is installed inside the cylinder of the drive motor, and a drive rod is installed on the piston's piston surface. A feeding rod extending into the cavity of the feeding cylinder is installed at the telescopic end of the drive rod, and a discharging rod extending into the cavity of the discharging cylinder is installed at the telescopic end of the feeding rod. An inlet and an outlet are respectively connected to the side wall of the discharging cylinder. The inlet of the pressure-stabilizing pump is connected to an external water source through a first pipe, and the outlet of the pressure-stabilizing pump is connected to the bottom of the pressure-stabilizing tank through a second pipe. A third pipe is connected to the top of the pressure-stabilizing tank. A flow regulating component is provided on the first pipe, and a pressure buffer component is provided on the third pipe.

[0007] Furthermore, a bypass pipe is connected in parallel to the second pipe, and a bypass valve is connected in series on the bypass pipe. The diameter of the bypass pipe is smaller than the diameter of the second pipe, and a reinforcing joint is provided at the connection between the bypass pipe and the second pipe.

The inner wall of the sealing cap is provided with a rubber sealing layer.

[0009] Furthermore, the flow regulating assembly includes a regulating valve body, a regulating valve core, and a regulating rod. The regulating valve body is connected in series with the first pipe.

[0010] Furthermore, pressure gauges are installed on the first pipe, the second pipe, the third pipe, and the bypass pipe, and a manual regulating valve is connected in parallel on the second pipe.

[0011] Furthermore, the first, second, third, and bypass pipes are all connected by flanges.

[0012] Furthermore, the outer wall of the pressure stabilizing tank is wrapped with an insulation layer, which is made of polyurethane foam. The outer wall of the insulation layer is wrapped with a protective shell, which is made of stainless steel and has an anti-rust coating on its outer wall.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves stable water pressure by coordinating the drive motor of the pressure stabilizing pump, the feeding cylinder, and the discharging cylinder. Combined with the water storage and buffering function of the pressure stabilizing tank, it can dynamically balance the pressure inside the pipe.

[0021] Furthermore, a pump mounting bracket 6 is provided on one side of the upper surface of the support base 1. A pressure stabilizing pump is fixedly connected to the pump mounting bracket 6 by bolts. The pressure stabilizing pump includes a drive motor 7, a feeding cylinder 8, and a discharging cylinder 9. The feeding cylinder 8 is installed at the bottom of the drive motor 7, and the discharging cylinder 9 is installed at the bottom of the feeding cylinder 8. A piston 10 is installed inside the cylinder of the drive motor 7. A drive rod 11 is installed on the piston 10. A feeding rod 12 extending into the cavity of the feeding cylinder 8 is installed at the telescopic end of the drive rod 11. A discharging rod 13 extending into the cavity of the discharging cylinder 9 is installed at the telescopic end of the feeding rod 12. A water inlet and a water outlet are connected to the side wall of the discharging cylinder 9, respectively. The water inlet of the pressure stabilizing pump is connected to an external water source through a first pipe 14. The water outlet of the pressure stabilizing pump is connected to the bottom of the pressure stabilizing tank 2 through a second pipe 15. A third pipe 16 is connected to the top of the pressure stabilizing tank 2. A flow regulating component is provided on the first pipe 14, and a pressure buffer component 21 is provided on the third pipe 16. The flow regulation assembly includes a regulating valve body 17, a regulating valve core 18, and a regulating rod 19. The regulating valve body 17 is connected in series with the first pipe 14. The regulating valve core 18 is rotatably connected inside the regulating valve body 17. One end of the regulating rod 19 is fixedly connected to the regulating valve core 18, and the other end extends to the outside of the regulating valve body 17 and is connected to an regulating handle 20. A sealing ring is provided at the connection between the regulating valve body 17 and the first pipe 14.

[0022] Furthermore, a bypass pipe 22 is connected in parallel to the second pipe 15, and a bypass valve 23 is connected in series to the bypass pipe 22. The diameter of the bypass pipe 22 is smaller than the diameter of the second pipe 15, and a reinforcing joint 24 is provided at the connection between the bypass pipe 22 and the second pipe 15. Pressure gauges 25 are installed on the first pipe 14, the second pipe 15, the third pipe 16, and the bypass pipe 22. A manual regulating valve 26 is also connected in parallel to the second pipe 15. The first pipe 14, the second pipe 15, the third pipe 16, and the bypass pipe 22 are all connected by flanges 27.

[0023] Furthermore, the pressure stabilizing tank 2 is provided with an air replenishment component at the top. The air replenishment component includes an air replenishment connector 28, a one-way valve 29, and a sealing cap 30. The air replenishment connector 28 is connected to the top of the pressure stabilizing tank 2. The one-way valve 29 is located inside the air replenishment connector 28. The sealing cap 30 is threaded to the outside of the air replenishment connector 28. A rubber sealing layer is provided on the inner wall of the sealing cap 30.

[0024] The working process of this utility model is as follows: First, turn the adjusting handle 20 to drive the adjusting rod 19 and the adjusting valve core 18 to rotate synchronously. By changing the flow cross-sectional area between the valve core and the valve body, the flow rate of the water entering the pressure stabilizing pump is adjusted. The sealing ring at the connection between the adjusting valve body 17 and the first pipe 14 can effectively prevent water leakage and ensure that the water source is efficiently delivered to the inlet of the pressure stabilizing pump.

[0025] After the water source enters the pressure stabilizing pump, the drive motor 7 starts and drives the piston 10 inside the cylinder to reciprocate. The piston 10 drives the feeding rod 12 to extend and retract in the feeding cylinder 8 through the drive rod 11. The feeding rod 12 further pushes the unloading rod 13 to move synchronously in the unloading cylinder 9. The volume change of the unloading cylinder 9 generates stable pressure, pressurizing the water source from the inlet and pushing it to the outlet. The pressurized water flows through the second pipe 15 to the bottom of the pressure stabilizing tank 2. During this process, the pressure gauge 25 on the second pipe 15 monitors the pressure value in the pipe in real time. If the pressure is within the normal range, the water flows directly into the pressure stabilizing tank 2 through the second pipe 15. If the pressure in the second pipe 15 is abnormal due to a sudden change in water demand, it can be assisted by the parallel manual regulating valve 26. The valve opening is manually turned to balance the pressure in the pipe and ensure stable water delivery.

[0026] The pressure stabilizing tank 2 maintains stable internal pressure through the top air replenishment component. If the internal pressure increases due to increased water volume, excess gas can be temporarily stored in the air replenishment component cavity through the one-way valve 29 in the air replenishment connector 28. After the pressure stabilizes, the one-way valve 29 automatically closes. If the internal pressure decreases due to water consumption, the sealing cap 30 can be opened, and the required gas can be replenished into the tank through the air replenishment connector 28. The one-way valve 29 ensures that the gas enters the tank in only one direction, preventing backflow of water. After replenishment, the sealing cap 30 is tightened, and its inner rubber sealing layer further enhances the sealing performance and prevents gas leakage.

[0027] Meanwhile, the polyurethane foam insulation layer 3 on the outside of the pressure stabilizing tank 2 can effectively isolate the influence of external temperature and prevent the water in the tank from freezing in low temperature environment or deteriorating in high temperature environment; the outer stainless steel protective shell 4 and anti-rust coating 5 protect the insulation layer 3 and the pressure stabilizing tank 2 from external corrosion and collision damage, and extend the service life of the equipment.

[0028] Water in the pressure stabilizing tank 2 is delivered to the user's pipeline through the top third pipe 16. The pressure buffer component 21 on the third pipe 16 can respond to pressure fluctuations in real time, alleviate pressure shocks in the pipe, and ensure that the water supply pressure is always stable within the design range.

[0029] If the water flow is obstructed due to a malfunction in the second pipeline 15, the bypass valve 23 on the bypass pipeline 22 can be opened in an emergency. The bypass pipeline 22 has a smaller diameter than the second pipeline 15 and can maintain the basic water supply of the pressure tank 2 through a small flow rate, thus preventing water outages for users. The reinforced joint 24 at the connection between the bypass pipeline 22 and the second pipeline 15 enhances the connection strength and prevents leakage or breakage of the joint due to the impact of high-pressure water flow.
