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 during 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 situations such as pipeline resistance changes or pump performance fluctuations occur 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 - backflow function, existing flow distribution devices generally have deficiencies. Many devices do not have a reliable anti - backflow mechanism, or the anti - backflow structures adopted are simple and ineffective. When water flow has a backflow situation, it is unable to quickly and effectively prevent the reverse flow of water. Water backflow not only causes water quality pollution problems, such as pouring the already used water that may contain impurities or pollutants back into the clean water source; it also causes damage to equipment. The reverse pressure generated by the backflow may impact 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 backflows will further accelerate the aging and damage of equipment, shorten the service life of equipment, and increase the maintenance and replacement costs. Therefore, we propose an anti - backflow flow distribution device. Summary of the Invention

[0016] A water distribution method for a flow distribution device with anti-backflow includes the following steps: Step 1: Device startup and initial data acquisition; 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; Step 12. Power on and start the flow distribution control meter, and the flow distribution control system starts to work; the data acquisition module starts to collect relevant data, the device set flow meter measures the water flow in the flow distribution pipeline in real time, and transmits the flow data to the flow distribution control meter through the connecting wire; 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 meter; Step 2: Data processing and analysis; Step 21. The data processing module of the flow distribution control system receives the flow data from the device set flow meter and the pressure data from the pressure monitoring system; 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; Step 3: Flow regulation operation; 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 execution mechanism and the flow regulating mechanism; Step 32. After the actuator receives the control instruction, the electromagnetic push rod starts to act; the electromagnetic push rod pushes the actuating contact rod, triggering the actuating solenoid valve and the water distribution tap electromagnetic starting connector to control the on / off and distribution of water flow. Step 33. The flow regulating valve body of the flow regulating mechanism responds to the control instruction, and the valve stem drives the regulating valve core to move, and the cooperation between the regulating valve core and the valve flap changes, thereby changing the flow area of the flow regulating valve body to achieve the regulation of water flow. Step 4: Backflow prevention protection. Step 41. During the water distribution process, the magnetic backflow prevention mechanism continuously functions; when the water flows normally, the magnetic push rod pushes the magnetic flap cone away from the check seal ring under the action of water pressure, and the water can pass through the magnetic check valve body smoothly. Step 42. If there is a situation of water flow backflow, the magnetic flap cone quickly fits tightly with the check seal ring under the action of the reverse water 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. Step 5: Real-time monitoring and feedback adjustment. Step 51. The pressure monitoring system continuously monitors the pressure changes inside the flow regulating mechanism and the magnetic backflow prevention mechanism, and feeds the real-time pressure data back to the flow distribution control table. Step 52. The device integrated flow meter also continuously updates the flow data; the data processing module of the flow distribution control system analyzes again based on the new data to judge whether the flow regulation reaches the expected effect. 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 to further regulate the flow until the actual flow matches the preset target flow and the system pressure is within the normal range. Step 6: Data display and recording. Step 61. The flow distribution display on the flow distribution control table real-time displays the current flow and pressure data, which is convenient for the operator to intuitively understand the operation status of the water distribution device. 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. Step 7: Device shutdown. Step 71. When the water distribution task is completed, turn off the execution power module to stop the operation of the electromagnetic push rod, the actuating solenoid valve and the water distribution tap electromagnetic starting connector. Step 72. The flow distribution control table stops working, and the entire backflow prevention flow distribution device stops running.

[0017] Compared with the prior art, the beneficial effects of the present invention: The flowmeter of the device of the present invention can accurately measure the water flow in the flow distribution pipeline in real time and transmit the data to the flow distribution control table. The data processing module of the flow 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 command based on the deviation value, driving the actuator and the flow regulating mechanism to act. The flow regulating valve body drives the regulating valve core to move through the valve stem, changing the flow area, realizing the precise regulation of the water flow, ensuring that the water distribution flow can accurately reach the preset target, and meeting the water distribution requirements in different scenarios.

[0018] The pressure monitoring system of the present invention continuously monitors the pressure changes inside the flow regulating mechanism and the magnetic anti-backflow mechanism, and the flowmeter of the device also continuously updates the flow 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 command 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.

[0019] 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.

[0020] 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 pipelines and equipment, reduce the probability of system failures, extend the service life of equipment, and reduce maintenance and replacement costs.

[0021] 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, and the operator can intuitively understand the operating status of the water distribution device. This facilitates the operator to discover problems in a timely manner and take corresponding measures, improving the convenience and timeliness of operation.

[0022] 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, helping technicians summarize the laws and problems in the water distribution process, optimizing the water distribution plan and system parameters, and providing a strong basis for the maintenance and upgrade of the system.

[0023] 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 by bolts; the flow distribution pipeline is connected to the flow regulating valve body through a connecting flange and tightly connected by fastening bolts. This design makes the installation, disassembly and maintenance of the device more convenient, improves work efficiency and reduces maintenance costs.

It should be noted that similar reference numerals and letters denote 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.

[0030] The flow regulating mechanism 6 is provided with a flow regulating valve body 61, the flow regulating valve body 61 is provided with a valve rod 63, the valve rod 63 is connected to a regulating valve core 64, the regulating valve core 64 is matched with a valve flap 62, and a valve cover 65 is arranged at the upper end of the flow regulating valve body 61.

[0031] The magnetic anti-backflow mechanism 7 is provided with a magnetic check valve body 71, a magnetic guide sleeve 72 is arranged in the magnetic check valve body 71, a magnetic push rod 73 is arranged in the magnetic guide sleeve 72, a magnetic flap cone block 74 is arranged at the end of the magnetic push rod 73, the magnetic flap cone block 74 is matched with a check valve sealing ring 75, and a magnetic adsorption block 76 is arranged at the upper end of the magnetic flap cone block 74. The flow regulating valve body 61 and the magnetic check valve body 71 are connected by a valve body flange and fixedly connected by bolts.

[0032] The end of the flow distribution pipe 2 is provided with a connecting flange 8, on which fastening bolts 9 are arranged, and a sealing gasket 10 is arranged at the connection of the connecting flange 8. A flow distribution display 11 is arranged on the flow distribution control table 4. The pressure monitoring system is provided with a pressure sensor 12, which is arranged inside the flow regulating mechanism 6 and the magnetic anti-backflow mechanism 7. The flow distribution pipe 2 is connected to the flow regulating valve body 61 through the connecting flange 8 and is tightly connected through 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.

[0033] The working principle of the anti-backflow flow distribution device: The device-integrated flowmeter 1 is installed on the flow distribution pipe 2, and its function is to measure the water flow through the pipe in real time. The measured flow data will be transmitted to the flow distribution control table 4 through the connecting wire 3. The data acquisition module in the flow distribution control table 4 receives these data, providing a basic basis for subsequent control and adjustment.

[0034] The data processing module of the flow distribution control system analyzes the collected flow data. The operator can preset the target distribution flow in the system in advance. The data processing module compares the actual measured flow with the target flow 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 regulating mechanism 6 and the magnetic anti-backflow mechanism 7, and it collects the pressure data in the system in real time and transmits it to the data processing module. The control module generates corresponding control instructions according to the flow deviation and pressure data based on the preset control algorithm.

[0035] The flow distribution control table 4 sends the 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, it pushes the actuating contact rod 52, and then triggers the actuating solenoid valve 54 and the water distribution tapping electromagnetic starting connector 55. The actuating solenoid valve 54 controls the on-off of the water flow, and the water distribution tapping electromagnetic starting connector 55 can realize the distribution of the water flow, thus initially adjusting the water flow condition entering the flow regulating mechanism 6.

[0036] 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 adjustment 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, thus realizing the precise regulation of the flow and making the actual flow gradually approach the preset target flow.

[0037] The magnetic anti - reflux mechanism 7 plays an important role in preventing water flow from flowing back during the entire water distribution process. In the case 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 moves away from the check valve sealing ring 75, allowing water to 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, making the magnetic flap cone block 74 quickly and tightly fit 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.

[0038] The pressure monitoring system works continuously, constantly feeding back the pressure data within the system to the flow water distribution control table 4. The device - integrated flowmeter 1 also continuously updates the flow data. The data processing module will analyze again based on the new data to determine whether the flow regulation has achieved the expected effect. If there is still a deviation between the actual flow and the target flow or the system pressure is abnormal, the control module will readjust the control instruction and drive the actuator 5 and the flow regulation 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.

[0039] The flow water distribution display 11 on the flow water distribution control table 4 real - time displays important data such as the current flow and pressure, facilitating the operator to intuitively understand the operating state of the water distribution device. The operator can interact with the flow water distribution control system through the control display module to set the target flow, view historical data, and achieve effective monitoring and management of the water distribution process. Embodiment 2: A water distribution method for an anti - reflux flow water distribution device, including the following steps: Step 1: Device startup and initial data acquisition; 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; 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 acquisition module starts to collect relevant data. The device - integrated 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; 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 anti - reflux mechanism 7, and transmits the data to the flow water distribution control table 4; Step 2: Data processing and analysis; 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; Step 22. According to the preset water distribution flow target value, the data processing module conducts a comparative analysis on the collected actual flow data to calculate the flow deviation value; meanwhile, it analyzes the pressure data to determine whether the system pressure is within the normal range; Step 3: Flow regulation operation; Step 31. If there is a deviation between the actual flow and the preset target flow, the control module generates a control instruction based on the flow deviation value and sends the instruction to the actuator 5 and the flow regulation mechanism 6; Step 32. After receiving the control instruction, the actuator 5 makes the electromagnetic push rod 51 start to act; the electromagnetic push rod 51 pushes the actuating rod 52 to trigger the actuating solenoid valve 54 and the water distribution tap electromagnetic starting connector 55 to control the on-off and distribution of water flow; Step 33. The flow regulating valve body 61 of the flow regulation mechanism 6 responds to the control instruction, and 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 regulating valve body 61 to achieve the regulation of the water flow; Step 4: Anti-backflow protection; Step 41. During the water distribution process, the magnetic anti-backflow mechanism 7 continuously functions; when the water flow is flowing normally, the magnetic push rod 73 pushes the magnetic flap cone block 74 away from the check sealing ring 75 under the action of the water flow pressure, and the water can pass through the magnetic check valve body 71 smoothly; Step 42. If there is a situation of water flow backflow, the magnetic flap cone block 74 quickly fits tightly with the check sealing ring 75 under the action of the reverse water flow pressure and the magnetic force of the magnetic adsorption block 76 to prevent the water flow from backflowing and ensure the unidirectionality of the water distribution process; Step 5: Real-time monitoring and feedback adjustment; 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 water distribution control table 4; Step 52. The device set flowmeter 1 also continuously updates the flow data; the data processing module of the flow water distribution control system analyzes again based on the new data to determine whether the flow regulation has achieved the expected effect; Step 53. If the flow still does not reach the preset target value or the pressure appears abnormal, the control module will adjust the control instruction again, repeat step three, and further regulate the flow until the actual flow is consistent with the preset target flow and the system pressure is within the normal range; Step 6: Data display and recording; Step 61. The flow distribution display 11 on the flow distribution control table 4 displays the current flow rate and pressure data in real time, facilitating the operator to intuitively understand the operating status of the water distribution device; Step 62. The data processing module of the flow distribution control system records the collected flow rate, pressure data, and relevant information during the adjustment process for subsequent data analysis and system maintenance; Step 7: Device shutdown; Step 71. After the water distribution task is completed, the execution power module 53 is turned off, and the operation of the execution electromagnetic push rod 51, the execution solenoid valve 54, and the water distribution tapping electromagnetic starting connector 55 is stopped; Step 72. The flow distribution control table 4 stops working, and the entire anti-backflow flow distribution device stops operating.

[0040] Working process of the water distribution method of the anti-backflow flow distribution device: Startup and data acquisition stage: 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: The execution power module 53 is turned on to supply power to the execution electromagnetic push rod 51, the execution solenoid valve 54, and the water distribution tapping electromagnetic starting connector 55, making the actuator 5 in a standby state ready to act at any time, providing a power basis for subsequent flow rate adjustment operations.

[0041] System startup and flow rate data acquisition: The flow distribution control table 4 is powered on and starts up, and the flow distribution control system starts running. The device set flowmeter 1 starts to measure the water flow rate in the water distribution pipeline 2 in real time, and transmits the measured flow rate data to the flow distribution control table 4 through the connecting wire 3, providing a basis for subsequent flow rate analysis and adjustment. Pressure data acquisition: The pressure sensor 12 in the pressure monitoring system starts to work, collects the pressure inside the flow rate adjustment mechanism 6 and the magnetic anti-backflow mechanism 7 in real time, and transmits the pressure data to the flow distribution control table 4 to monitor the system pressure condition and ensure that the water distribution process is carried out within a safe pressure range.

[0042] Data processing and analysis stage: This stage processes and analyzes the collected data to provide a decision-making basis for flow rate adjustment. Data reception: The data processing module of the flow distribution control system receives the flow rate data from the device set flowmeter 1 and the pressure data from the pressure monitoring system.

[0043] Comparison and analysis: The data processing module compares the collected actual flow rate data with the preset water distribution flow rate target value, calculates the flow rate 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 rate or the system.

[0044] Flow regulation operation stage: According to the results of data processing and analysis, the flow rate is adjusted to make the actual flow rate approach the preset target flow rate. Instruction generation and transmission: If there is a deviation between the actual flow rate and the preset target flow rate, the control module generates corresponding control instructions based on the flow deviation value and sends the instructions to the actuator 5 and the flow regulation mechanism 6.

[0045] Actuation of actuator 5: After receiving the control instruction, the electromagnetic push rod 51 of the actuator 5 starts to act, pushing the actuating rod 52, triggering the actuating solenoid valve 54 and the water distribution tapping electromagnetic starting connector 55, thereby controlling the on / off and distribution of water flow and achieving preliminary regulation of the flow rate.

[0046] Regulation of the flow regulation valve body 61: The flow regulation valve body 61 of the flow regulation mechanism 6 responds to the control instruction, and the valve stem 63 drives the regulating valve core 64 to move, changing the cooperation state between the regulating valve core 64 and the valve flap 62, and further changing the flow area of the flow regulation valve body 61 to achieve precise regulation of the water flow rate.

[0047] 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.

[0048] Treatment of backflow situation: If there is a backflow of water, 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.

[0049] Real-time monitoring and feedback adjustment stage: In this stage, through continuous monitoring and feedback, the accuracy and stability of the water distribution process are ensured. Data feedback: The pressure monitoring system continuously monitors the pressure changes inside the flow regulation 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 rate data.

[0050] Re-analysis and adjustment: The data processing module of the flow distribution control system analyzes again based on the new data to determine whether the flow regulation has achieved the expected effect.

10. A water distribution method of a flow water distribution device with backflow prevention, characterized in that: The following steps are involved: Step 1: Device startup and initial data collection; Step 11. Turn on the execution power module (53) to provide power to the execution electromagnetic push rod (51), the execution electromagnetic valve (54) and the water distribution junction electromagnetic start connector (55), so that the actuator (5) is in a standby state; Step 12. The flow distribution control table (4) is powered on and started, and the flow distribution control system starts to work; the data acquisition module starts to collect relevant data, and the device flow meter (1) measures the water flow in the flow distribution pipe (2) in real time, and transmits the flow data to the flow distribution control table (4) through the connecting wire (3); Step 13. The pressure sensor (12) in the pressure monitoring system starts to work, collects pressure data inside the flow regulating mechanism (6) and the magnetic backflow prevention mechanism (7), and transmits the data to the flow distribution control table (4); Step 2: Data processing and analysis; Step 21. The data processing module of the flow distribution control system receives the flow data from the device flow meter (1) and the pressure data from the pressure monitoring system; 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; Step 3: flow regulation operation; 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 according to the flow rate deviation value, and sends the instruction to the actuator (5) and the flow regulating mechanism (6); Step 32. After the actuator (5) receives the control command, the electromagnetic push rod (51) starts to move; the electromagnetic push rod (51) pushes the actuator touch rod (52), triggering the actuator electromagnetic valve (54) and the water distribution junction electromagnetic start connector (55), thereby controlling the on / off and distribution of the water flow; Step 33. The flow regulating valve body (61) of the flow regulating mechanism (6) responds to the control command, and the valve stem (63) drives the regulating valve core (64) to move, so that the coordination between the regulating valve core (64) and the valve flap (62) changes, thereby changing the flow area of ​​the flow regulating valve body (61) to achieve water flow regulation; Step 4: Anti-backflow protection; Step 41. During the water distribution process, the magnetic backflow prevention mechanism (7) continues to function; when the water flows normally, the magnetic push rod (73) pushes the magnetic flap cone block (74) away from the check seal ring (75) under the action of the water flow pressure, and the water can smoothly pass through the magnetic check valve body (71); Step 42. If water backflow occurs, the magnetic flap cone block (74) quickly fits tightly with the check ring (75) under the reverse pressure of the water flow and the magnetic force of the magnetic adsorption block (76), thereby preventing water backflow and ensuring the unidirectionality of the water distribution process; Step 5: Real-time monitoring and feedback adjustment; Step 51. The pressure monitoring system continuously monitors the pressure changes inside the flow regulating mechanism (6) and the magnetic backflow prevention mechanism (7), and feeds back the real-time pressure data to the flow distribution control table (4); Step 52. The flow meter (1) of the device 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 achieves the expected effect; 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 command again and repeat step 3 to further adjust the flow rate until the actual flow rate matches the preset target flow rate and the system pressure is within the normal range; Step 6: Data display and recording; Step 61. The flow distribution display (11) on the flow distribution control table (4) displays the current flow and pressure data in real time, so that the operator can intuitively understand the operating status of the water distribution device; Step 62. The data processing module of the flow distribution control system records the collected flow and pressure data and related information during the regulation process for subsequent data analysis and system maintenance; Step 7: The device is turned off; Step 71. When the water distribution task is completed, the execution power module (53) is turned off, and the execution electromagnetic push rod (51), the execution electromagnetic valve (54) and the water distribution junction electromagnetic start connector (55) are stopped; Step 72: The flow distribution control table (4) stops working, and the entire anti-backflow flow distribution device stops operating.
