Description

Technical Field

[0001] This utility model relates to the field of water supply equipment, and in particular to a residual pressure recovery mechanism for secondary water supply equipment. Background Technology

[0002] To address the issue of insufficient pressure in municipal water supply networks, high-rise buildings often need to be equipped with secondary water supply systems. These systems increase water pressure by storing tap water and boosting its pressure, thereby meeting users' water demands during peak periods.

[0003] In existing technologies, secondary water supply equipment requires frequent startup of booster pumps to meet the water storage needs of elevated water tanks and the water demand of multiple users. Especially during off-peak water usage periods, even small water demands from users can trigger the booster pumps, thereby increasing energy consumption and affecting the service life of the booster pumps. Improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a residual pressure recovery mechanism for secondary water supply equipment, which recovers residual pressure from tap water supply pipes and booster pumps to reduce energy consumption.

[0005] To achieve this objective, the present invention adopts the following technical solution: A residual pressure recovery mechanism for a secondary water supply system includes: a tap water supply pipe, a flow stabilizing tank, a control cabinet, a booster pump, an elevated water tank, and a residual pressure recovery component. The tap water supply pipe is connected to the inlet of the flow stabilizing tank. A first water pipe is provided between the outlet of the flow stabilizing tank and the inlet of the booster pump. The residual pressure recovery component includes a steel cylinder and a plunger. An inlet pipe connector is provided on the upper part of one side of the elevated water tank. The steel cylinder is vertically arranged on one side of the inlet pipe connector. A valve hole communicating with the inlet pipe connector is provided on the side of the steel cylinder. The plunger is vertically and movably arranged in the steel cylinder. A second water pipe is provided between the outlet of the booster pump and the bottom of the steel cylinder. Water pipes are spaced apart on the side of the second water pipe. A third water pipe connected to the second water pipe is provided at the bottom of the elevated water tank. An electric valve is provided on the third water pipe. The control cabinet is connected to the booster pump and the electric valve for operation control.

[0006] The upper and lower parts of the outer wall of the plunger are respectively provided with sealing rings that contact the inner wall of the steel cylinder.

[0007] The flow stabilizing tank is equipped with a pressure sensor, which is connected to the control cabinet to transmit signals.

[0008] The flow stabilizing tank is equipped with a vacuum suppressor.

[0009] The plunger is made of stainless steel.

[0010] The steel cylinder is equipped with a crossbeam at the top, and a distance sensor pointing downwards towards the plunger is installed in the crossbeam. The distance sensor is connected to the control cabinet to transmit signals.

[0011] The high-level water tank is equipped with a liquid level sensor, which is connected to the control cabinet to send signals.

[0012] The beneficial effects of this utility model are as follows: A residual pressure recovery mechanism for a secondary water supply device, during normal water use, pressurizes the water supply through the cooperation of the tap water supply pipe and the booster pump to meet the user's water demand. The residual pressure is used to lift the plunger, allowing tap water to enter the high-level water tank through the valve hole for storage. A portion of the tap water is stored in the steel cylinder to recover residual pressure. During peak water usage periods, the electric valve can be opened to replenish water from the high-level water tank. During off-peak water usage periods, the booster pump can be turned off, and the tap water in the steel cylinder can be used to temporarily supply water to users. The plunger's own weight can also be used to increase the pressure, ensuring the water supply pressure. Attached Figure Description

[0014] The following is combined with Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] like Figure 1 The residual pressure recovery mechanism of the secondary water supply equipment shown includes: a tap water supply pipe 8, a flow stabilizing tank 7, a control cabinet 10, a booster pump 5, a high-level water tank 12, and a residual pressure recovery component. The tap water supply pipe 8 is connected to the inlet of the flow stabilizing tank 7 to deliver tap water into the flow stabilizing tank 7.

[0016] A vacuum suppressor is installed on the flow stabilizing tank 7 to detect and manage vacuum, effectively suppressing negative pressure at the inlet of the flow stabilizing tank 7. A pressure sensor 9 is installed on the flow stabilizing tank 7, and the pressure sensor 9 is connected to the control cabinet 10 to send signals, ensuring that the control cabinet 10 receives the water pressure value of the flow stabilizing tank 7.

[0017] In this embodiment, the residual pressure recovery assembly includes a steel cylinder 1 and a plunger 2. An inlet pipe joint 13 is provided on the upper part of one side of the high-level water tank 12. The steel cylinder 1 is vertically arranged on one side of the inlet pipe joint 13 and can be connected and fixed by a flange, which is convenient for assembly.

[0018] The steel cylinder 1 has a valve hole 14 on its side that communicates with the water inlet pipe connector 13. The plunger 2 is vertically and flexibly installed in the steel cylinder 1. Figure 1 As shown, the plunger 2 closes the valve orifice 14 when it descends. In this embodiment, the upper and lower parts of the outer wall of the plunger 2 are respectively provided with sealing rings 17 that contact the inner wall of the steel cylinder 1 to avoid leakage. The plunger 2 is made of stainless steel, which is heavy and has good corrosion resistance.

[0019] A first water pipe 6 is installed between the outlet of the flow stabilizing tank 7 and the inlet of the booster pump 5. A second water pipe 3 is installed between the outlet of the booster pump 5 and the bottom of the steel cylinder 1. Water pipes 18 are installed at intervals on the side of the second water pipe 3 to meet the water needs of users on different floors. Through the cooperation of the tap water supply pipe 8 and the booster pump 5, pressurized water supply is provided to meet the users' water needs, and residual pressure is used to lift the plunger 2. Figure 2 As shown, after the plunger 2 rises, its bottom is higher than the bottom of the valve hole 14, opening the valve hole 14 so that tap water enters the high-level water tank 12 through the valve hole 14 for water storage, and stores some tap water through the steel cylinder 1 to achieve residual pressure recovery.

[0020] A third water pipe 4, connected to the second water pipe 3, is provided at the bottom of the high-level water tank 12. An electric valve 11 is provided on the third water pipe 4. The control cabinet 10 is connected to the booster pump 5 and the electric valve 11 for operation control, thereby improving the level of automation. During peak water usage periods, when the water pressure in the flow stabilizing tank 7 drops, the electric valve 11 can be opened to replenish water from the high-level water tank 12, thus meeting the water supply requirements of the water pipe 18 for users.

[0021] A liquid level sensor 16 is installed on the high-level water tank 12. The liquid level sensor 16 is connected to the control cabinet 10 to send signals and realize the liquid level monitoring of the high-level water tank 12. After the water level of the high-level water tank 12 reaches the standard, the booster pump 5 can be temporarily shut down to reduce energy consumption.

[0022] like Figure 1 As shown, a crossbeam 19 is provided at the top of the steel cylinder 1, and a distance sensor 15 pointing downwards towards the plunger 2 is installed in the crossbeam 19. The distance sensor 15 is connected to the control cabinet 10 to send signals and realize the position and height detection of the plunger 2, which is beneficial to the control of the booster pump 5. The plunger 2 is located at... Figure 2 When the water level is high, the booster pump 5 is temporarily shut down to further reduce energy consumption. During periods of low water usage, after the plunger 2 rises, the booster pump 5 is shut down, and the tap water below the plunger 2 in the steel cylinder 1 temporarily supplies water to the second water pipe 3 to meet the occasional water supply needs of users. The pressure is increased by the weight of the plunger 2 to ensure the water supply pressure. This helps to extend the downtime of the booster pump 5, reduce the starting frequency of the booster pump 5, reduce energy consumption, and extend the service life of the booster pump 5.

[0023] Piston 2 descends to Figure 1 When the pressure is low, the booster pump 5 is turned on to supply water to the second water pipe 3, while the plunger 2 is lifted and water is stored, thus realizing the utilization of residual pressure.
