Description

Technical Field

[0001] The present invention relates to the technical field of water distribution devices, and more particularly, to a flow water distribution device with anti-backflow function. Background Art

[0002] Flow water distribution devices are widely used in many fields, such as industrial production, agricultural irrigation, and building water supply and drainage. Their main function is to accurately distribute the water flow according to requirements to meet the water use requirements in different scenarios. However, many deficiencies have emerged in the actual use of existing flow water distribution devices, making it difficult to achieve an ideal water distribution effect.

[0003] A modular flow water distribution device proposed in Chinese Patent Application No. CN202311312322.5; includes a housing, an inlet, an outlet, a pipe body, and a flow control mechanism; the two ends of the pipe body are set as the inlet and the outlet, the housing is perpendicular to the pipe body and internally connected; the flow control mechanism is installed inside the housing and extends into the pipe body. The flow control mechanism adjusts the rotation intensity of the impeller in the flow resistance component through the intermittent clamping and fixing of the clamping wheel, thereby changing the water flow velocity in the current pipe body; the present invention adjusts the flow resistance component by controlling the rotation intensity of the impeller, so as to be able to change the water flow velocity in the pipe body in real time and accurately to adapt to different working conditions and requirements, not only ensuring the uniformity of water flow distribution, but also reducing the pressure in the pipeline and extending the service life of the pipeline.

[0004] In terms of flow regulation and control, most existing flow water distribution devices lack an effective closed-loop feedback regulation mechanism. These devices often only adjust the flow rate based on the initially set parameters and cannot continuously monitor the pressure changes inside the flow regulation mechanism and update the flow rate data in real time during the water distribution process. Once there are situations such as pipeline resistance changes or pump performance fluctuations in the water distribution system, the device cannot obtain these dynamic information in a timely manner and make corresponding adjustments. This results in the flow rate being difficult to always remain stable within the preset range, greatly reducing the accuracy and stability of water distribution, and may affect the normal progress of subsequent production or use links.

[0005] Regarding the anti - reflux function, the existing flow distribution devices generally have deficiencies. Many devices do not have a reliable anti - reflux mechanism, or the anti - reflux structures adopted are simple and ineffective. When water flow shows a reflux situation, it is unable to quickly and effectively prevent the reverse flow of water. Water flow reflux will not only cause water quality pollution problems, such as pouring the already used water that may contain impurities or pollutants back into the clean water source; it will also damage the equipment. The reverse pressure generated by the reflux may impact the pipelines and equipment, loosen the pipeline joints, exacerbate the wear of equipment components, and increase the probability of system failures. Moreover, the excessive pressure fluctuations in the pipeline caused by frequent reflux will further accelerate the aging and damage of the equipment, shorten the service life of the equipment, and increase the maintenance and replacement costs. Therefore, we propose a flow distribution device with anti - reflux function. Summary of the Invention

[0016] A water distribution method for an anti-backflow flow distribution device includes the following steps:

[0017] Step 1: Device startup and initial data acquisition;

[0018] Step 11. Turn on the execution power module to provide power for the execution electromagnetic push rod, the execution solenoid valve and the water distribution tapping electromagnetic start connector, so that the execution mechanism is in a standby state;

[0019] Step 12. Power on and start the flow distribution control table, and the flow distribution control system starts to work; the data acquisition module starts to collect relevant data, the device set flowmeter measures the water flow in the flow distribution pipe in real time, and transmits the flow data to the flow distribution control table through the connecting wire;

[0020] Step 13. The pressure sensor in the pressure monitoring system starts to work, collects the pressure data inside the flow regulating mechanism and the magnetic anti-backflow mechanism, and transmits the data to the flow distribution control table;

[0021] Step 2: Data processing and analysis;

[0022] Step 21. The data processing module of the flow distribution control system receives the flow data from the device set flowmeter and the pressure data from the pressure monitoring system;

[0023] Step 22. According to the preset water distribution flow target value, the data processing module compares and analyzes the collected actual flow data, calculates the flow deviation value; at the same time, analyzes the pressure data to judge whether the system pressure is within the normal range;

[0024] Step 3: Flow regulation operation;

[0025] Step 31. If there is a deviation between the actual flow rate and the preset target flow rate, the control module generates a control instruction based on the flow deviation value and sends the instruction to the actuator and the flow regulation mechanism;

[0026] Step 32. After receiving the control instruction, the actuator makes the electromagnetic push rod start to act; the electromagnetic push rod pushes the actuating contact rod, triggering the actuating solenoid valve and the water distribution tapping electromagnetic starting connector to control the on-off and distribution of water flow;

[0027] Step 33. The flow regulation valve body of the flow regulation mechanism responds to the control instruction, and the valve stem drives the regulating valve core to move, changing the cooperation between the regulating valve core and the valve flap, thereby changing the flow area of the flow regulation valve body to achieve the regulation of the water flow rate;

[0028] Step 4: Backflow prevention protection;

[0029] Step 41. During the water distribution process, the magnetic backflow prevention mechanism continuously functions; when the water flow is normal, the magnetic push rod pushes the magnetic flap cone away from the check valve sealing ring under the action of the water flow pressure, and the water can smoothly pass through the magnetic check valve body;

[0030] Step 42. If there is a situation of water flow backflow, the magnetic flap cone quickly fits tightly with the check valve sealing ring under the action of the reverse water flow pressure and the magnetic force of the magnetic adsorption block, preventing the water flow from flowing back and ensuring the unidirectionality of the water distribution process;

[0031] Step 5: Real-time monitoring and feedback adjustment;

[0032] Step 51. The pressure monitoring system continuously monitors the pressure changes inside the flow regulation mechanism and the magnetic backflow prevention mechanism, and feeds back the real-time pressure data to the flow distribution control table;

[0033] Step 52. The device integrated flowmeter also continuously updates the flow data; the data processing module of the flow distribution control system analyzes the new data again to determine whether the flow regulation has achieved the expected effect;

[0034] Step 53. If the flow rate still does not reach the preset target value or the pressure is abnormal, the control module will adjust the control instruction again and repeat step three to further regulate the flow rate until the actual flow rate matches the preset target flow rate and the system pressure is within the normal range;

[0035] Step 6: Data display and recording;

[0036] Step 61. The flow distribution display on the flow distribution control table continuously displays the current flow rate and pressure data, facilitating the operator to intuitively understand the operation status of the water distribution device;

[0037] Step 62. The data processing module of the flow water distribution control system records the collected flow rate, pressure data, and relevant information during the adjustment process for subsequent data analysis and system maintenance;

[0038] Step 7: The device is shut down;

[0039] Step 71. After the water distribution task is completed, the execution power module is shut down, and the operation of the execution electromagnetic push rod, execution solenoid valve, and water distribution tapping electromagnetic starting connector is stopped;

[0040] Step 72. The flow water distribution control table stops working, and the entire anti-backflow flow water distribution device stops operating.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] The flowmeter of the device of the present invention can accurately measure the water flow rate in the flow water distribution pipeline in real time and transmit the data to the flow water distribution control table. The data processing module of the flow water distribution control system compares and analyzes the actual flow rate with the preset target flow rate, and calculates the flow deviation value. The control module generates a control instruction based on the deviation value, and drives the actuator and the flow regulation mechanism to act. The flow regulation valve body drives the regulating valve core to move through the valve stem, changes the flow area, and realizes the precise regulation of the water flow rate, ensuring that the water distribution flow rate can accurately reach the preset target and meet the water distribution requirements in different scenarios.

[0043] The pressure monitoring system of the present invention continuously monitors the pressure changes inside the flow regulation mechanism and the magnetic anti-backflow mechanism, and the flowmeter of the device also continuously updates the flow rate data. The data processing module analyzes again according to the new data. If the flow rate does not reach the target or the pressure is abnormal, the control module will timely adjust the control instruction and repeat the flow regulation operation, forming a closed-loop feedback regulation mechanism, ensuring that the flow rate is always stable within the preset range during the water distribution process, and improving the accuracy and stability of water distribution.

[0044] The magnetic anti-backflow mechanism of the present invention plays an important role in the water distribution process. When the water flows normally, the magnetic push rod pushes the magnetic flap cone away from the check valve sealing ring under the action of the water flow pressure, ensuring the smooth passage of water; if there is a water flow backflow situation, the magnetic flap cone quickly fits tightly with the check valve sealing ring under the action of the reverse water flow pressure and the magnetic force of the magnetic adsorption block, preventing the water flow from flowing back, ensuring the unidirectionality of the water distribution process, and avoiding problems such as water quality pollution and equipment damage caused by backflow.

[0045] The realization of the anti-backflow function of the present invention helps to protect the safe and stable operation of the entire water distribution system. Preventing backflow can avoid excessive pressure fluctuations in the pipeline, reduce the impact on the pipeline and equipment, reduce the probability of system failures, extend the service life of the equipment, and reduce the maintenance and replacement costs.

[0046] The flow distribution display on the flow distribution control table of the present invention can display the current flow rate and pressure data in real time, enabling the operator to intuitively understand the operating status of the water distribution device. This facilitates the operator to promptly detect problems and take corresponding measures, improving the convenience and timeliness of operation.

[0047] The data processing module of the flow distribution control system of the present invention records the collected flow rate, pressure data, and relevant information during the adjustment process. These recorded data can be used for subsequent data analysis to help technicians summarize the rules and problems in the water distribution process, optimize the water distribution plan and system parameters, and provide a strong basis for the maintenance and upgrade of the system.

[0048] Each part of the device of the present invention adopts a modular design. For example, the flow regulating valve body and the magnetic check valve body are connected through a valve body flange and fixed with bolts; the flow distribution pipeline is connected to the flow regulating valve body through a connecting flange and tightly connected with fastening bolts. This design makes the installation, disassembly, and maintenance of the device more convenient, improves work efficiency, and reduces maintenance costs. Brief Description of the Drawings

It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0065] Embodiment 1: A flow water distribution device with anti - reflux function, including a device set flowmeter 1. The device set flowmeter 1 is connected to a flow water distribution pipeline 2. The device set flowmeter 1 is connected to a flow water distribution control table 4 through a connecting wire 3. A flow water distribution control system is provided in the flow water distribution control table 4. The flow water distribution control table 4 is connected to an actuator 5 and a flow regulating mechanism 6. The actuator 5 and the flow regulating mechanism 6 are electrically connected to a pressure monitoring system. The flow regulating mechanism 6 is connected to a magnetic anti - reflux mechanism 7. The actuator 5 is connected to an actuating electromagnetic push rod 51. The actuating electromagnetic push rod 51 is connected to an actuating contact rod 52. The actuating electromagnetic push rod 51 is connected to an actuating power supply module 53 in a circuit. The actuating power supply module 53 is connected to an actuating solenoid valve 54 and a water distribution tap electromagnetic starting connector 55.

[0066] The flow rate regulating mechanism 6 is provided with a flow rate regulating valve body 61. The flow rate regulating valve body 61 is provided with a valve stem 63. The valve stem 63 is connected to a regulating valve core 64. The regulating valve core 64 cooperates with a valve flap 62. The upper end of the flow rate regulating valve body 61 is provided with a valve cover 65.

[0067] The magnetic anti - backflow mechanism 7 is provided with a magnetic check valve body 71. Inside the magnetic check valve body 71, there is a magnetic guide sleeve 72. Inside the magnetic guide sleeve 72, there is a magnetic push rod 73. At the end of the magnetic push rod 73, there is a magnetic flap cone 74. The magnetic flap cone 74 cooperates with a check valve sealing ring 75. The upper end of the magnetic flap cone 74 is provided with a magnetic adsorption block 76. The flow rate regulating valve body 61 and the magnetic check valve body 71 are connected through a valve body flange and fixedly connected by bolts.

[0068] At the end of the flow distribution pipe 2, there is a connecting flange 8. On the connecting flange 8, there are fastening bolts 9. At the connection of the connecting flange 8, there is a sealing gasket 10. On the flow distribution control meter 4, there is a flow distribution display 11. The pressure monitoring system is provided with a pressure sensor 12. The pressure sensor 12 is arranged inside the flow rate regulating mechanism 6 and the magnetic anti - backflow mechanism 7. The flow distribution pipe 2 is connected to the flow rate regulating valve body 61 through the connecting flange 8 and fixedly connected by the fastening bolts 9. The flow distribution control system is provided with a control module, a data processing module, a data acquisition module, and a control display module.

[0069] The working principle of the anti - backflow flow distribution device: The device - integrated flow meter 1 is installed on the flow distribution pipe 2, and its function is to measure the water flow rate through the pipe in real - time. The measured flow rate data will be transmitted to the flow distribution control meter 4 through the connecting wire 3. The data acquisition module in the flow distribution control meter 4 receives these data, providing a basic basis for subsequent control and regulation.

[0070] The data processing module of the flow distribution control system analyzes the collected flow rate data. The operator can preset the target distribution flow rate in the system in advance. The data processing module compares the actually measured flow rate with the target flow rate and calculates the deviation between the two. At the same time, the pressure sensor 12 of the pressure monitoring system is arranged inside the flow rate regulating mechanism 6 and the magnetic anti - backflow mechanism 7, collecting the pressure data in the system in real - time and transmitting it to the data processing module. The control module generates corresponding control instructions according to the flow rate deviation and pressure data based on the preset control algorithm.

[0071] The flow distribution control table 4 sends control instructions to the actuator 5. The actuator power module 53 in the actuator 5 provides power support for the entire actuator part. When receiving the control instructions, the actuating electromagnetic push rod 51 starts to act, which pushes the actuating contact rod 52, and then triggers the actuating solenoid valve 54 and the water distribution tap electromagnetic starting connector 55. The actuating solenoid valve 54 controls the on-off of the water flow, and the water distribution tap electromagnetic starting connector 55 can realize the distribution of the water flow, thereby initially adjusting the water flow condition entering the flow regulating mechanism 6.

[0072] The flow regulating valve body 61 of the flow regulating mechanism 6 is the key component to achieve precise flow regulation. On the basis of the initial regulation of the actuator 5, the flow regulating valve body 61 further adjusts the flow according to the control instructions. The control instructions cause the valve stem 63 to act, and the valve stem 63 drives the regulating valve core 64 to move. The regulating valve core 64 cooperates with the valve flap 62, and by changing the relative position between the two, the flow area of the flow regulating valve body 61 is adjusted. The change of the flow area directly affects the water flow through volume, thereby realizing the precise regulation of the flow rate, and making the actual flow rate gradually approach the preset target flow rate.

[0073] The magnetic anti-backflow mechanism 7 plays an important role in preventing water flow back during the entire water distribution process. Under the condition of the normal water flow direction, the pressure of the water flow pushes the magnetic push rod 73 to move within the magnetic guide sleeve 72, and the magnetic flap cone block 74 at the end of the magnetic push rod 73 leaves the check valve sealing ring 75, and the water can pass through the magnetic check valve body 71 smoothly. When the water flow reverses, on the one hand, the pressure generated by the reverse water flow will push the magnetic flap cone block 74 towards the check valve sealing ring 75; on the other hand, the magnetic adsorption block 76 will generate a magnetic force to attract the magnetic flap cone block 74, so that the magnetic flap cone block 74 quickly fits tightly with the check valve sealing ring 75 to form a seal, thereby preventing the water flow from flowing back and ensuring the unidirectionality and stability of the water distribution process.

[0074] The pressure monitoring system works continuously and constantly feeds back the pressure data in the system to the flow distribution control table 4. The device integrated flowmeter 1 also continuously updates the flow data. The data processing module will analyze again according to the new data to judge whether the flow regulation reaches the expected effect. If there is still a deviation between the actual flow rate and the target flow rate or the system pressure is abnormal, the control module will readjust the control instructions and drive the actuator 5 and the flow regulating mechanism 6 to perform corresponding actions again, forming a closed-loop feedback regulation system to ensure the stable and precise operation of the water distribution device.

[0075] The flow distribution display 11 on the flow distribution control table 4 displays the important data of the current flow rate and pressure in real time, which is convenient for the operator to intuitively understand the operation state of the water distribution device. The operator can interact with the flow distribution control system through the control display module, set the target flow rate, view the historical data, and realize the effective monitoring and management of the water distribution process.

[0076] Embodiment 2: A water distribution method for a backflow prevention flow water distribution device, comprising the following steps:

[0077] Step 1: Device startup and initial data collection;

[0078] Step 11. Turn on the execution power module 53 to provide power for the execution electromagnetic push rod 51, the execution solenoid valve 54, and the water distribution tap electromagnetic start connector 55, so that the actuator 5 is in a standby state;

[0079] Step 12. Power on and start the flow water distribution control table 4, and the flow water distribution control system starts to work; the data collection module starts to collect relevant data, the device set flowmeter 1 measures the water flow in the flow water distribution pipeline 2 in real time, and transmits the flow data to the flow water distribution control table 4 through the connecting wire 3;

[0080] Step 13. The pressure sensor 12 in the pressure monitoring system starts to work, collects the pressure data inside the flow regulation mechanism 6 and the magnetic backflow prevention mechanism 7, and transmits the data to the flow water distribution control table 4;

[0081] Step 2: Data processing and analysis;

[0082] Step 21. The data processing module of the flow water distribution control system receives the flow data from the device set flowmeter 1 and the pressure data from the pressure monitoring system;

[0083] Step 22. According to the preset water distribution flow target value, the data processing module compares and analyzes the collected actual flow data, and calculates the flow deviation value; at the same time, analyzes the pressure data to determine whether the system pressure is within the normal range;

[0084] Step 3: Flow regulation operation;

[0085] Step 31. If there is a deviation between the actual flow and the preset target flow, the control module generates a control instruction according to the flow deviation value and sends the instruction to the actuator 5 and the flow regulation mechanism 6;

[0086] Step 32. After receiving the control instruction, the execution electromagnetic push rod 51 of the actuator 5 starts to act; the execution electromagnetic push rod 51 pushes the execution contact rod 52, triggers the execution solenoid valve 54 and the water distribution tap electromagnetic start connector 55, and controls the on-off and distribution of water flow;

[0087] Step 33. The flow regulation valve body 61 of the flow regulation mechanism 6 responds to the control instruction, the valve stem 63 drives the regulating valve core 64 to move, and the cooperation between the regulating valve core 64 and the valve flap 62 changes, thereby changing the flow area of the flow regulation valve body 61 to achieve the regulation of the water flow;

[0088] Step 4: Anti-backflow protection;

[0089] Step 41. During the water distribution process, the magnetic anti-backflow mechanism 7 continuously functions. When the water flows normally, the magnetic push rod 73 pushes the magnetic flap cone block 74 away from the check valve sealing ring 75 under the action of the water flow pressure, and the water can smoothly pass through the magnetic check valve body 71.

[0090] Step 42. If the water flow backflows, the magnetic flap cone block 74 quickly fits tightly with the check valve sealing ring 75 under the action of the reverse water flow pressure and the magnetic force of the magnetic adsorption block 76, preventing the water flow from flowing back and ensuring the unidirectionality of the water distribution process.

[0091] Step 5: Real-time monitoring and feedback adjustment;

[0092] Step 51. The pressure monitoring system continuously monitors the pressure changes inside the flow regulation mechanism 6 and the magnetic anti-backflow mechanism 7, and feeds the real-time pressure data back to the flow distribution control table 4.

[0093] Step 52. The device set flowmeter 1 also continuously updates the flow data. The data processing module of the flow distribution control system analyzes the new data again to determine whether the flow regulation has achieved the expected effect.

[0094] Step 53. If the flow still does not reach the preset target value or the pressure is abnormal, the control module will adjust the control instruction again, repeat step three, further adjust the flow until the actual flow matches the preset target flow and the system pressure is within the normal range.

[0095] Step 6: Data display and recording;

[0096] Step 61. The flow distribution display 11 on the flow distribution control table 4 real-time displays the current flow and pressure data, facilitating the operator to intuitively understand the operating status of the water distribution device.

[0097] Step 62. The data processing module of the flow distribution control system records the collected flow, pressure data and relevant information during the adjustment process for subsequent data analysis and system maintenance.

[0098] Step 7: Device shutdown;

[0099] Step 71. When the water distribution task is completed, turn off the execution power module 53 to stop the operation of the execution electromagnetic push rod 51, the execution solenoid valve 54 and the water distribution tap electromagnetic start connector 55.

[0100] Step 72. The flow distribution control table 4 stops working, and the entire anti-backflow flow distribution device stops operating.

[0101] Water distribution method working process of the anti - backflow flow water distribution device: Startup and data acquisition stage:

[0102] This stage is the preparation stage for the entire water distribution process, ensuring that all parts of the device work properly and obtaining initial data. The actuator 5 is on standby: Turn on the actuator power module 53 to supply power to the actuator electromagnetic push rod 51, the actuator solenoid valve 54, and the water distribution branch electromagnetic start connector 55, so that the actuator 5 is in a standby state ready to act at any time, providing a power basis for subsequent flow regulation operations.

[0103] System startup and flow data acquisition: The flow water distribution control table 4 is powered on and starts, and the flow water distribution control system starts to run. The device set flowmeter 1 starts to measure the water flow in the flow water distribution pipeline 2 in real - time, and transmits the measured flow data to the flow water distribution control table 4 through the connecting wire 3, providing a basis for subsequent flow analysis and regulation. Pressure data acquisition: The pressure sensor 12 in the pressure monitoring system starts to work, collects the pressure inside the flow regulation mechanism 6 and the magnetic anti - backflow mechanism 7 in real - time, and transmits the pressure data to the flow water distribution control table 4, which is used to monitor the system pressure condition to ensure that the water distribution process is carried out within a safe pressure range.

[0104] Data processing and analysis stage: This stage processes and analyzes the collected data to provide a decision - making basis for flow regulation. Data reception: The data processing module of the flow water distribution control system receives the flow data from the device set flowmeter 1 and the pressure data from the pressure monitoring system.

[0105] Comparison and analysis: The data processing module compares the actually measured flow data with the preset water distribution flow target value, calculates the flow deviation value. At the same time, analyzes the pressure data to determine whether the system pressure is within the normal range to decide whether to adjust the flow or the system.

[0106] Flow regulation operation stage: According to the results of data processing and analysis, adjust the flow to make the actual flow approach the preset target flow. Instruction generation and sending: If there is a deviation between the actual flow and the preset target flow, the control module generates corresponding control instructions according to the flow deviation value and sends the instructions to the actuator 5 and the flow regulation mechanism 6.

[0107] The actuator 5 acts: After the actuator 5 receives the control instruction, the actuator electromagnetic push rod 51 starts to act, pushes the actuator contact rod 52, triggers the actuator solenoid valve 54 and the water distribution branch electromagnetic start connector 55, thereby controlling the on - off and distribution of water flow and realizing the preliminary regulation of the flow.

[0108] Flow regulating valve body 61 adjustment: The flow regulating valve body 61 of the flow regulating mechanism 6 responds to the control instruction, and the valve stem 63 drives the regulating valve core 64 to move, changing the mating state between the regulating valve core 64 and the valve flap 62, thereby changing the flow area of the flow regulating valve body 61 and achieving precise adjustment of the water flow.

[0109] Backflow prevention protection stage: During the water distribution process, the magnetic backflow prevention mechanism 7 continuously functions to ensure the unidirectionality of the water flow. Normal water flow condition: When the water flows normally, the magnetic push rod 73 pushes the magnetic flap cone 74 away from the check valve sealing ring 75 under the action of the water flow pressure, enabling the water to pass through the magnetic check valve body 71 smoothly and ensuring the normal progress of the water distribution process.

[0110] Treatment of backflow situation: If a backflow of water occurs, the magnetic flap cone 74 quickly fits tightly with the check valve sealing ring 75 under the action of the reverse water flow pressure and the magnetic force of the magnetic adsorption block 76 to form a seal, preventing the backflow of water and ensuring the safety and stability of the water distribution process.

[0111] Real-time monitoring and feedback adjustment stage: This stage ensures the accuracy and stability of the water distribution process through continuous monitoring and feedback. Data feedback: The pressure monitoring system continuously monitors the pressure changes inside the flow regulating mechanism 6 and the magnetic backflow prevention mechanism 7 and feeds the real-time pressure data back to the flow distribution control table 4. At the same time, the device integrated flowmeter 1 continuously updates the flow data.

[0112] Re-analysis and adjustment: The data processing module of the flow distribution control system analyzes the new data again to determine whether the flow regulation has achieved the expected effect. If the flow still does not reach the preset target value or the pressure is abnormal, the control module will adjust the control instruction again, repeat the flow regulation operation steps, and further adjust the flow until the actual flow matches the preset target flow and the system pressure is within the normal range.

[0113] Data display and recording stage: Provide support for real-time data display for operators and subsequent data analysis. Real-time data display: The flow distribution display 11 on the flow distribution control table 4 real-time displays the current flow and pressure data, facilitating the operators to intuitively understand the operation status of the water distribution device so as to promptly discover problems and handle them.

[0114] Data recording: The data processing module of the flow distribution control system records the collected flow, pressure data and relevant information during the adjustment process, providing historical data support for subsequent data analysis and system maintenance, which helps to optimize the water distribution process and improve the performance of the device.

[0115] Device shutdown phase: When the water distribution task is completed, stop the operation of the device to ensure the safety and energy conservation of the device. The actuator 5 stops working: Turn off the actuator power module 53, stop the operation of the actuator electromagnetic push rod 51, the actuator solenoid valve 54 and the water distribution tapping electromagnetic starting connector 55, and cut off the power supply to the actuator 5. The system stops running: The flow water distribution control table 4 stops working, and the entire anti-backflow flow water distribution device stops running, ending the current water distribution process.
