Description

TECHNICAL FIELD

[0001] The utility model belongs to water supply system technical field, concretely relates to a kind of different water level automatic pressure-boosting water supply system. BACKGROUND

[0002] Traditional water supply system usually relies on reservoir to store water. The water in these reservoirs is usually supplied by pressurized tap water. So-called "pressurized water" refers to the water directly delivered from the water supply network, which itself has a certain water pressure.

[0003] When pressurized water enters the reservoir, the water pressure will disappear. This is because the water enters the reservoir and is no longer in the delivery process, the water pressure is released and cannot be used continuously. Therefore, the loss of this water pressure means that the energy consumed in the delivery process is not fully utilized, resulting in energy waste.

[0004] In order to deliver the water in the reservoir again, a booster or water pump is usually needed to boost the water pressure. If the water supply demand is unstable, the booster may need to be started frequently or in a low-efficiency running state for a long time, which will increase the idle time of the equipment. Long-time idling or low-efficiency running will cause the equipment to wear out, shorten its service life, increase maintenance and replacement costs. And this kind of water supply mode has low degree of automation, needs special person to monitor the equipment running state, increases the labor cost and management difficulty. It can be seen that the traditional water supply mode relying on reservoir has the problems of energy waste, fast equipment wear and tear, low running efficiency and high management cost. SUMMARY

[0005] In view of the problems existing in the prior art, the utility model provides a different water level automatic pressure-boosting water supply system, which aims to replace the work of water pump with automatic exhaust and double-control water level controller to avoid idling, and use the pressure of municipal pipe network to realize energy-saving and efficient water supply function, while ensuring that the water tower is naturally unobstructed when the water pressure is high. The structure is simple, the land area is small, and the installation and maintenance are convenient and fast.

[0008] Further, the float valve is installed at the water outlet of the booster pump, and the float valve is higher than the stop water level probe two of the water supply type water level controller.

[0009] Further, the distance between the float valve and the stop water level probe two of the water supply type water level controller is 10cm-15cm.

[0010] Further, the distance between the bottom of the water tower and the exhaust valve is 1m-8m.

[0011] Further, the distance between the exhaust valve and the water inlet pipe is 2.8m-18m.

[0015] 2. High automation degree: through the automatic control of the water level controller, the system can automatically adjust the water supply state according to the water level change, without manual intervention, the labor cost and management difficulty are reduced.

[0023] The present application will be further explained and described below with reference to the accompanying drawings and specific embodiments. It should be noted that the specific embodiments are not intended to limit the scope of the present invention.

[0024] like Figure 1As shown, the automatic booster water supply system with different water levels provided in this specific embodiment includes an exhaust pipe 16, a tee 17, a sealing cover 6, an automatic exhaust valve 5, a booster pump 8, a check valve 7, a water supply type water level controller 13, a drainage type water level controller 11, a water tower 15, and a float valve 9.

[0025] The exhaust pipe 16 is a six-point water pipe. The exhaust pipe 16 is connected to the water inlet pipe 1 of the municipal pipe network and the main pipe interface of the tee 17. The sealing cover 6 and the automatic exhaust valve 5 are respectively installed on the branch pipe interface of the tee 17. The automatic exhaust valve 5 is an A11 model Alcys brand micro-inlet and exhaust valve purchased from Taobao.

[0026] The vent pipe 16, connecting the inlet pipe 1 and the automatic vent valve 5, serves three main functions: First, it guides air out, providing a passage for air within the pipe to pass smoothly through the automatic vent valve 5 and be discharged from the system. This is crucial for eliminating air resistance and improving water flow. Second, the vent pipe 16 ensures timely removal of air from the pipe, reducing air obstruction to water flow and allowing the booster pump 8 to operate more efficiently. Third, in conjunction with the automatic vent valve 5, the vent pipe 16 continuously discharges air from the pipe, preventing water pressure instability and water supply interruptions caused by air accumulation.

[0027] The automatic air vent valve 5 serves four main purposes: First, it expels air from the pipeline to prevent airlock caused by air accumulation. Airlock affects water flow, reduces water supply efficiency, and can even lead to abnormal operation of the booster pump 8. Second, it prevents water hammer. When the water flow in the pipeline changes suddenly, the presence of air can trigger water hammer, causing impact and damage to the pipeline and equipment. The automatic air vent valve 5 reduces water hammer by promptly venting air, protecting the pipeline system and equipment. Third, it ensures the normal operation of the water supply system. When the water supply system starts up, the automatic air vent valve 5 quickly expels air from the pipeline, filling it with water and ensuring the booster pump 8 can operate normally, improving the system's operating efficiency and stability. Fourth, it prevents backflow. The automatic air vent valve 5 works in conjunction with the check valve 7 to prevent water backflow when the pump stops, avoiding damage to the booster pump 8 due to backflow during dry running.

[0028] The inlet of booster pump 8 is connected to the outlet of inlet pipe 1, and the outlet of booster pump 8 is connected to the top of water tower 15. The functions of booster pump 8 are: 1) to pressurize the water in inlet pipe 1 and deliver it to water tower 15; 2) to automatically adjust the water supply pressure based on signals from drainage-type water level controller 11. When the water level in water tower 15 drops to the set start-up water level, booster pump 8 starts, increasing the water pressure; when the water level in water tower 15 reaches the set stop-pump water level, booster pump 8 stops working, ensuring stable water pressure in the water supply system; 3) through cooperation with the water level controller, booster pump 8 only operates when necessary, avoiding unnecessary idling and inefficient operation, reducing energy consumption, and improving system operating efficiency; 4) the start and stop of booster pump 8 are automatically controlled by drainage-type water level controller 11, preventing equipment damage due to insufficient or excessive water levels. Meanwhile, the cooperation between the check valve 7 and the automatic exhaust valve 5 can also prevent the booster pump 8 from running dry due to backflow, thus extending the service life of the equipment.

[0029] The check valve 7 is installed between the exhaust pipe 16 and the booster pump 8. The function of the automatic exhaust valve 5 and the check valve 7 is to prevent the booster pump 8 from running dry after the water flows back when the pump stops, so as to achieve the effect of energy saving and avoid damage to the booster pump 8 due to the dry running caused by the water flow reversal.

[0030] Both the water supply level controller 13 and the drainage level controller 11 are CX-37 model fully automatic water tower level controllers, purchased from Taobao. The pump stop and start level probes of the water supply level controller 13 and the drainage level controller 11 are installed in reverse order. Specifically, the drainage level controller 11 controls the booster pump 8 via electrical connection. The sealing cover 6 has an opening. The pump stop level probe 2 and the start level probe 3 of the drainage level controller 11 are respectively suspended inside the vent pipe 16 through the opening of the sealing cover 6. Sealant is poured into the opening to prevent air from escaping from the vent pipe 16. The start level probe 3 is located above the pump stop level probe 2; that is, the position of the start level probe 3 of the drainage level controller 11 is the start level line set inside the vent pipe 16, and the position of the pump stop level probe 2 of the drainage level controller 11 is the pump stop level line set inside the vent pipe 16. The water supply level controller 13 is electrically connected to the drainage level controller 11. The pump stop level probe 18 and the start level probe 19 of the water supply level controller 13 are respectively suspended inside the water tower 15, and the pump stop level probe 18 is higher than the start level probe 19. That is, the position of the start level probe 18 of the water supply level controller 13 is the start level line set inside the water tower 15, and the position of the pump stop level probe 19 of the water supply level controller 13 is the pump stop level line set inside the water tower 15.

[0031] To prevent a sudden increase in water pressure in the municipal water supply network, or other pressure fluctuations in the system that could cause a temporary rise in the water level in the water tower, or a malfunction in the water level controller or booster pump, a float valve 9 is installed at the outlet of the booster pump 8 to prevent water from overflowing from the water tower 15, serving as a last line of defense. ， Furthermore, the float valve 9 is positioned higher than the second pump-stop water level probe 18 of the water supply level controller 13, and the distance 10 between the float valve 9 and the second pump-stop water level probe 18 of the water supply level controller 13 is 10cm to 15cm. This ensures that before the float valve 9 closes, the second pump-stop water level probe 18 has accurately detected that the water level has reached the pump-stop height, thus stopping the booster pump 8 in time and preventing overflow due to excessively high water levels in the water tower 15. The water level in the water tower 15 may fluctuate briefly due to changes in water demand or fluctuations in water supply pressure. If the distance between the float valve 9 and the second pump-stop water level probe 18 is too small, both the float valve 9 and the second pump-stop water level probe 18 may be triggered simultaneously during water level fluctuations, leading to malfunctions (such as frequent start-stop of the booster pump). By setting a distance of 10cm to 15cm, a certain buffer space can be provided for water level fluctuations, avoiding system malfunctions caused by brief water level fluctuations and improving system stability.

[0032] The function of the float valve 9 is to automatically adjust the opening and closing of the valve according to the water level in the water tower 15. When the water level in the water tower 15 rises, the float rises, causing the valve to close and preventing the tap water in the water tower 15 from overflowing; when the water level in the water tower 15 drops, the float falls, the valve opens, and tap water is added to the water tower 15.

[0033] The drainage-type water level controller 11 controls the start and stop of the booster pump 8 based on the water level in the exhaust pipe 16, ensuring that the system can automatically adjust the water supply status according to changes in the water level in the exhaust pipe 16. When the start-up water level probe 3 of the drainage-type water level controller 11 detects that the water level in the exhaust pipe 16 has reached the set start-up water level, the drainage-type water level controller 11 automatically connects the power supply to the booster pump 8, causing the booster pump 8 to start working and transport water from the inlet pipe 1 to the water tower 15. When the stop-pump water level probe 2 of the drainage-type water level controller 11 detects that the water level in the exhaust pipe 16 has dropped to the set stop-pump water level, the drainage-type water level controller 11 automatically cuts off the power supply to the booster pump 8, causing the booster pump 8 to stop working, thereby avoiding unnecessary energy consumption and equipment wear. By precisely controlling the start and stop of the booster pump 8, the booster pump 8 is prevented from running dry due to insufficient water level, extending the service life of the equipment and improving the operating efficiency of the system.

[0034] The function of the water supply level controller 13 is to monitor the water level changes in the water tower 15 and work in conjunction with the drainage level controller 11 to ensure that the water level in the water tower 15 is always maintained within a reasonable range. When the start-up level probe 19 of the water supply level controller 13 detects that the water level in the water tower 15 has dropped to the set start-up level, the drainage level controller 11 sends a signal to control the booster pump 8 to start and replenish water to the water tower 15. When the stop-pump level probe 18 of the water supply level controller 13 detects that the water level in the water tower 15 has risen to the set stop-pump level, the drainage level controller 11 cuts off the power to the booster pump 8, stops the water supply, and prevents water from overflowing from the water tower 15. Through cooperation with the drainage level controller 11, the water supply level controller 13 can adjust the water supply status in a timely manner according to the water level changes in the water tower 15, ensuring stable water pressure in the water tower 15 and meeting the user's water demand.

[0035] The bottom of the water tower 15 is higher than the automatic air vent valve 5, and the distance 14 between the bottom of the water tower 15 and the automatic air vent valve 5 is 1m to 8m. This serves two purposes: First, it effectively prevents backflow. When the booster pump 8 stops working, the check valve 7 closes, preventing water in the water tower 15 from flowing back into the inlet pipe 1. If the distance between the bottom of the water tower 15 and the automatic air vent valve 5 is too small, water in the water tower 15 may flow back to the position of the automatic air vent valve 5, or even enter the inlet pipe 1, due to pressure fluctuations or check valve failure, potentially causing system malfunctions or reducing system reliability. Second, the distance between the bottom of the water tower 15 and the automatic air vent valve 5 ensures that air in the vent pipe 16 can be discharged smoothly, while preventing water in the water tower 15 from entering the vent pipe 16 due to pressure fluctuations, thus interfering with the normal operation of the automatic air vent valve 5. Appropriate spacing ensures the efficiency and stability of the venting process. Third, this spacing reduces energy loss during system operation, improves water supply efficiency, and ensures that water can smoothly enter the water tower 15 from the inlet pipe 1 through the check valve 7 when the booster pump 8 is working. Simultaneously, when the pump stops, the check valve 7 and the automatic air vent 5 work together to prevent backflow and air accumulation. Fourth, the spacing between the bottom of the water tower 15 and the automatic air vent 5 is also related to water level control within the water tower 15. When the water level in the water tower 15 rises, the float valve 9 closes to prevent water from overflowing. If the spacing is too small, water in the water tower 15 may overflow during pressure fluctuations or affect the normal operation of the float valve 9. Therefore, an appropriate spacing ensures that the float valve 9 can accurately control the water level in the water tower 15, preventing overflow. The distance 4 between the automatic air vent valve 5 and the water inlet pipe 1 is 2.8m to 18m. This distance ensures sufficient space and path for air to be expelled from the pipe, preventing air accumulation. This distance also reduces air obstruction to water flow, making it smoother. When water flows through the water inlet pipe 1 into the air vent pipe 16, air can be smoothly expelled through the automatic air vent valve 5, reducing water flow resistance and improving the efficiency of the water supply system. When the water flow changes suddenly (such as when the booster pump 8 starts or stops), the water flow velocity in the pipe changes drastically, potentially causing water hammer. Water hammer can impact pipes and equipment, causing damage. Setting the distance between the automatic air vent valve 5 and the water inlet pipe 1 provides a buffer space for the water flow, reducing drastic changes in flow velocity. Simultaneously, the automatic air vent valve 5 can promptly expel air from the pipe, reducing air accumulation and thus lowering the probability of water hammer, protecting pipes and equipment. The distance between the automatic air vent valve 5 and the water inlet pipe 1 ensures that water in the pipe will not flow back to the booster pump 8 when the pump stops, thus preventing the booster pump 8 from running dry due to backflow. Dry running will lead to accelerated wear of the booster pump 8 and shorten its service life.

[0036] Working principle:

[0037] 1. Water level monitoring:

[0038] In use, the water level in the exhaust pipe 16 is monitored by the start-up water level probe 3 and the stop-pump water level probe 2 of the drainage type water level controller 11, and the water level in the water tower 15 is monitored by the start-up water level probe 18 and the stop-pump water level probe 19 of the water supply type water level controller 13.

[0039] 2. Water flow control:

[0040] Tap water enters the exhaust pipe 16 from the inlet pipe 1. When the start water level probe 3 of the drain-type water level controller 11 does not detect that the tap water in the exhaust pipe 16 has reached the set start water level, the check valve 7 is closed.

[0041] When the start-up water level probe 3 of the drainage-type water level controller 11 detects that the water level in the vent pipe 16 has reached the set start-up water level line, the drainage-type water level controller 11 controls the booster pump 8 to start, and the check valve 7 automatically opens to allow water flow. Tap water enters the water tower 15 through the check valve 7 and the booster pump 8, and the air in the inlet pipe 1 is discharged through the vent pipe 16 and the automatic air vent valve 5, ensuring that the pipe is full of water. When the stop-pump water level probe 2 of the water-type water level controller detects that the water level in the water tower 15 has risen to the stop-pump water level line, the drainage-type water level controller 11 controls the booster pump 8 to stop working. At this time, because the booster pump 8 stops running, the water pressure drops, and the check valve 7 automatically closes to prevent water in the water tower 15 from flowing back to the booster pump 8. If the water level in the water tower 15 rises to the position of the float valve 9, the float rises and drives the valve to close.

[0042] When the water level sensor 2 of the water-type water level controller detects that the water level in the water tower 15 has reached the set starting water level line in the water tower 15, the drainage-type water level controller 11 controls the booster pump 8 to start, replenishing water into the water tower 15. At this time, the float valve 9 automatically adjusts its opening and closing according to the water level in the water tower 15 to ensure the stability of the water level in the water tower 15.

[0043] When the pump stop water level probe 2 of the drainage type water level controller 11 detects that the water in the exhaust pipe 16 has dropped to the pump stop water level line, and the pump stop water level probe 2 of the water supply type water level controller 13 detects that the water level in the water tower 15 has reached the pump stop water level line, the drainage type water level controller 11 controls the booster pump 8 to stop working.

[0044] When the pump stop water level probe 2 of the water supply type water level controller 13 does not reach the set pump stop water level line in the water tower 15, and the start water level probe 3 of the drainage type water level controller 11 detects that the water level in the exhaust pipe 16 has risen to the start water level line, the drainage type water level controller 11 controls the power supply of the booster pump 8 to turn on.

[0045] 3. Handling Abnormal Situations:

[0046] If an abnormal water pressure occurs in the inlet pipe 1, the drainage-type water level controller 11 repeatedly controls the booster pump 8 to start or stop working based on whether the water level has reached the start-up water level line in the drainage pipe, until the water level in the water tower 15 reaches the stop-pump water level line, at which point the drainage-type water level controller 11 controls the booster pump 8 to stop working. Even if there is no water in the inlet pipe 1, it can ensure that there is water in the pipe between the check valve 7 and the water tower 15, thereby preventing water from flowing back into the booster pump 8 when the pump stops, and avoiding damage to the booster pump 8 due to reverse rotation.

[0047] 4. Water-based operation:

[0048] When water is needed, simply open the water supply port 12 of water tower 15.
