Description

Technical Field

[0001] This invention relates to the field of three-way ball valve technology, and more specifically, to a square three-way threaded ball valve. Background Technology

[0002] Most conventional three-way threaded ball valves on the market currently adopt a circular integral structure and a circular water passage chamber design. This results in a simplistic overall structure and poor compatibility between the internal cavity and various sealing and water passage fittings. The sealing structure of traditional three-way ball valves is mostly a fixed assembly design, where the contact force between the sealing components and the valve core remains constant, failing to adjust according to changes in the valve's on / off state and pipeline water flow conditions. During long-term water flow operations and frequent opening and closing operations, the fixed sealing structure is prone to gaps and localized leaks, leading to a continuous decline in sealing stability. This makes it difficult to adapt to complex and variable pipeline water flow scenarios, significantly limiting the equipment's usability.

[0003] Traditional three-way threaded ball valves generally lack intelligent monitoring and adaptive control systems. Core data such as water flow rate, cavity water pressure, sealing condition, and mechanism operating status during operation cannot be collected and fed back autonomously. Troubleshooting and operational monitoring rely entirely on regular manual inspections. This manual maintenance model is not only inefficient and costly, but also suffers from delayed fault detection and the inability to promptly identify minor issues. Furthermore, the constant sealing pressure causes continuous high-intensity friction on the sealing components throughout the valve's opening and closing process, leading to rapid wear and aging, significantly shortening service life. It also cannot adapt to the sealing requirements of different operating conditions such as high pressure, low pressure, large flow, and small flow, easily resulting in high-pressure leakage and excessive wear under low pressure, leading to insufficient overall operational reliability and practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a square three-way threaded ball valve to solve the problems mentioned in the background art.

[0005] A square three-way threaded ball valve includes a ball valve body. A bottom inlet fixing plate is fixedly installed at the bottom of the ball valve body. Side sealing plates are fixedly installed on both outer sides of the ball valve body. Outlet fixing plates are fixedly installed on the other two outer sides of the ball valve body. A connecting threaded cylinder is fixedly installed on the side of each outlet fixing plate away from the ball valve body. The ball valve body, the side sealing plates, the bottom inlet fixing plate, and the outlet fixing plate are connected in a square shape, and a square cavity is formed inside. A fixing seat is fixedly installed on the top of the ball valve body. A connecting shaft is rotatably installed inside the fixing seat. A control wrench is fixedly connected to the top of the connecting shaft on the top of the fixing seat. The bottom of the connecting shaft extends into the ball valve. Inside the main body, extending into the square cavity, a sealing ball seat is rotatably mounted inside the square cavity. The top of the sealing ball seat is fixedly connected to the bottom of the connecting shaft for sealing the two side sealing plates. An intelligent monitoring system is mounted on the top of the ball valve body. Sealing mechanisms are provided between the two side sealing plates inside the ball valve body and the sealing ball seat. An adjustment mechanism is provided at the bottom of the connecting shaft inside and on the top of the sealing ball seat. A ball seat outlet is opened at the bottom of the sealing ball seat and is connected to the bottom water inlet fixing plate. A ball seat inlet is opened on one side of the sealing ball seat and is connected to the ball seat outlet, and is used to connect the two water outlet fixing plates.

[0006] Preferably, the sealing mechanism includes a sealing ring that engages with the inner side of the water outlet fixing plate. One side of the sealing ring is tightly fitted with the sealing ball seat. The sealing ring is used to seal the connection surface when the water inlet of the ball seat is connected to the connecting threaded cylinder to prevent water leakage, and to prevent water from entering the interior of the water outlet fixing plate when the water inlet of the ball seat is not connected to the connecting threaded cylinder.

[0007] Preferably, a connecting ring is slidably disposed inside the connecting threaded cylinder. One side of the connecting ring is fixedly connected to the sealing ring. Multiple compression springs are fixedly disposed on the side of the connecting ring away from the sealing ring, and a compression plate is fixedly connected to the multiple compression springs. The compression plate is slidably disposed inside the water outlet fixed plate and is used to compress the sealing ring into contact with the sealing ball seat to increase the sealing force. A connecting plate is fixedly disposed on the top of the compression plate. The connecting plate is slidably disposed on the top inner side of the water outlet fixed plate and is connected to the adjusting mechanism to control the compression force of the compression plate on the sealing ring during the rotation of the connecting shaft, thereby reducing the friction between the sealing ring and the sealing ball seat while ensuring a seal.

[0008] Preferably, the adjusting mechanism includes an adjusting plate fixedly sleeved on the outside of the connecting shaft. The adjusting plate is located inside the top side of the ball valve body and at the top of the connecting shaft. A symmetrical concave quadrilateral groove is formed on the top outer side of the adjusting plate. A rotating seat is slidably arranged inside the concave quadrilateral groove. A transmission plate is fixedly arranged on the top of the rotating seat. One side of the transmission plate is fixedly connected to the connecting plate and is used to drive the adjusting plate to rotate on the connecting shaft. The rotating seat repeatedly slides along the arc inside the concave quadrilateral groove, pulling the connecting plate and the extrusion plate to compress the sealing ring. The extrusion force is greatest when the ball seat inlet is connected to the connecting threaded cylinder, and decreases otherwise.

[0009] Preferably, two fixing brackets are fixedly installed on one side of the water outlet fixing plate, and a sliding rod is fixedly connected between one side of the two fixing brackets and the water outlet fixing plate. A sliding block is fixedly installed on the top of the transmission plate, and the sliding block is movably sleeved on the outside of the two sliding rods to limit the movement of the transmission plate.

[0010] Preferably, the intelligent monitoring system includes a flow monitoring module, a pressure monitoring module, a data processing module, and a wireless transmission module. The intelligent monitoring system is fixedly mounted on the top of the ball valve body and wrapped around the outside of the fixed base. The intelligent monitoring system establishes electrical connections with the water flow path, sealing mechanism, and regulating mechanism inside the ball valve body, respectively, for comprehensive real-time monitoring of the water flow conditions inside the square chamber, the sealing status of the sealing ring, and the operating conditions of the regulating mechanism.

[0011] Preferably, the flow monitoring module is fixedly installed inside the water inlet passage of the bottom water inlet fixing plate. The flow monitoring module is set at the water inlet connection position corresponding to the water outlet of the ball seat, and is used to collect the water flow data flowing into the sealed ball seat through the bottom water inlet fixing plate in real time, and transmit the collected flow data to the data processing module in real time for summary analysis.

[0012] Preferably, the pressure monitoring module is symmetrically installed on the inner cavity wall of the two water outlet fixing plates. The pressure monitoring module is arranged close to the sealing area between the sealing ring and the sealing ball seat. It is used to detect the water pressure value of the internal cavity of the water outlet fixing plate in real time. By the fluctuation of the real-time water pressure value, it can determine whether there is a water leakage fault between the sealing ring and the sealing ball seat. At the same time, the collected water pressure data is transmitted to the data processing module in real time.

[0013] Preferably, the intelligent monitoring system further includes an audible and visual early warning module, which is fixedly installed on the top outer side of the mounting base and located on the side of the control wrench. The audible and visual early warning module is electrically connected to the data processing module. When the data processing module detects that the flow rate data or water pressure data exceeds the preset normal value range, it triggers the audible and visual early warning module to activate the audible and visual early warning prompt, thereby reminding the equipment operator that the ball valve has malfunctions such as abnormal water flow or sealing leakage.

[0014] Preferably, the data processing module has a built-in data storage unit and a working condition linkage control unit. The data storage unit is used to continuously store all working condition data collected by the flow monitoring module and the pressure monitoring module. The working condition linkage control unit is electrically connected to the adjustment mechanism and is used to match and adjust the rotation amplitude of the adjustment plate according to the real-time monitored water flow rate and chamber water pressure data, so as to accurately assist in adjusting the squeezing force of the squeezing plate on the sealing ring and adapt to the sealing operation requirements under different water flow conditions.

[0015] Compared with the prior art, the advantages of this invention are:

[0016] By adopting a square integrated cavity structure, coupled with a dynamically adaptive sealing mechanism, a linkage transmission adjustment structure, and a full-coverage intelligent monitoring and control system, this device thoroughly solves many technical defects of traditional three-way ball valves, such as fixed sealing force, severe component wear, unstable sealing performance, lack of autonomous monitoring capabilities, delayed fault handling, and poor adaptability to operating conditions, from multiple dimensions including structural optimization, friction reduction, operating condition monitoring, fault early warning, and intelligent linkage control. This equipment achieves integrated operation effects of dynamic adjustment of sealing force according to operating conditions, real-time monitoring of equipment operating conditions, proactive fault early warning, and intelligent linkage control of operating status. It significantly improves the operational stability, sealing reliability, and service life of three-way ball valves, while also enhancing the intelligent operation level of the equipment. It can be widely adapted to various complex pipeline water flow operation scenarios, significantly improving its versatility and practical value.

[0017] The equipment features a linked adaptive sealing structure that precisely balances sealing performance with component friction loss, fundamentally addressing the traditional ball valve's inability to simultaneously achieve both sealing and energy saving. This structure, relying on the elastic fit of the sealing ring, compression spring, and compression plate, combined with the linkage control of the adjustment mechanism, automatically increases the sealing pressure between the sealing ring and the sealing ball seat during water flow operations. This comprehensively seals any gaps in the water flow connection, completely eliminating high-pressure water leakage and seepage from gaps, ensuring the sealing performance during water flow operations. Conversely, when the ball valve is closed to cut off water, it actively reduces the sealing pressure, lowering the hard contact friction between sealing components. This prevents continuous high-intensity wear of sealing components during frequent opening and closing of the ball valve, effectively slowing down the aging and wear rate of core vulnerable components such as the sealing ring and sealing ball seat. This significantly extends the service life of the sealing components, reduces the probability of equipment sealing failures, and lowers the cost of subsequent component replacement and equipment maintenance.

[0018] The dedicated limit-guide transmission structure effectively ensures the accuracy and stability of the equipment's adjustment transmission system, avoiding the drawbacks of traditional ball valve transmission misalignment and adjustment jamming. By mounting a fixing bracket and sliding rod on the outside of the outlet fixing plate, and cooperating with the sliding block on the top of the transmission plate to form an integrated limit-guide component, the reciprocating movement trajectory of the transmission plate, connecting plate, and pressing plate can be precisely constrained, ensuring that the entire transmission adjustment process remains stable and regular, completely avoiding abnormal situations such as misalignment, shaking, displacement, and jamming during transmission. The stable transmission structure ensures that the sealing force adjustment accuracy is always within the standard range, eliminating faults such as uneven sealing force, local sealing failure, and adjustment malfunction caused by transmission misalignment, significantly improving the reliability of the equipment's mechanical transmission system, allowing the ball valve to adapt to long-term, high-frequency opening and closing operations, and effectively extending the overall service life of the equipment.

[0019] The integrated, fully-covered intelligent monitoring system enables 24 / 7 autonomous monitoring of ball valve operation, completely eliminating the shortcomings of traditional ball valve maintenance that relies on manual inspections. The system's flow monitoring and pressure monitoring modules have clearly defined roles and work in synergy. The flow monitoring module collects real-time water flow data at the inlet, accurately controlling the water flow status, while the pressure monitoring module focuses on the core sealing area, detecting real-time fluctuations in cavity water pressure and accurately capturing pressure changes caused by minor leaks in the sealing gaps. All collected operating data is transmitted in real-time to the data processing module for aggregation, analysis, and processing. This eliminates the need for frequent manual checks of equipment operation, allowing for precise 24 / 7 monitoring of ball valve water flow conditions, sealing status, and operational details. It enables timely detection of minor anomalies and potential sealing problems, preventing pipeline water flow failures at the source and significantly improving equipment maintenance efficiency and the safety and stability of pipeline water flow operations.

[0020] The intelligent audible and visual early warning and operating condition linkage control functions realize intelligent and adaptive control of equipment operation, greatly expanding the applicable operating conditions range of the equipment. The audible and visual early warning module can quickly trigger audible and visual early warning signals when the flow rate and water pressure data exceed the preset standard range, intuitively and promptly reminding operators of equipment malfunctions such as abnormal water flow and seal leakage, significantly shortening the time for fault detection and handling, and reducing the risk of water loss and equipment damage caused by faults. At the same time, the operating condition linkage control unit built into the data processing module can intelligently match and adjust the sealing compression force based on real-time monitored flow rate and water pressure data. It adaptively adjusts the sealing state for different operating conditions such as high pressure and high flow rate, and low pressure and low flow rate, which not only solves the leakage problem caused by insufficient sealing force under high pressure conditions, but also avoids component wear and resource waste caused by excessive sealing under low pressure conditions. This allows the ball valve to adapt to various complex and ever-changing pipeline water flow scenarios, significantly improving the equipment's versatility and intelligence level.

Detailed Implementation

[0031] Example: Please refer to Figures 1-9 A square three-way threaded ball valve includes a ball valve body 1. A bottom inlet fixing plate 11 is fixedly installed at the bottom of the ball valve body 1. Side sealing plates 10 are fixedly installed on both sides of the outer side of the ball valve body 1. Outlet fixing plates 3 are fixedly installed on the other two sides of the outer side of the ball valve body 1. A connecting threaded cylinder 30 is fixedly installed on the side of each outlet fixing plate 3 away from the ball valve body 1. The ball valve body 1 is connected to the side sealing plates 10, the bottom inlet fixing plate 11, and the outlet fixing plates 3 in a square shape, and a square cavity is formed inside. A fixing seat 2 is fixedly installed on the top of the ball valve body 1. A connecting shaft 21 is rotatably installed inside the fixing seat 2. A control wrench 20 is fixedly connected to the top of the connecting shaft 21 on the top of the fixing seat 2. The ball valve body 1 extends into the square chamber, where a sealing ball seat 22 is rotatably mounted. The top of the sealing ball seat 22 is fixedly connected to the bottom of the connecting shaft 21 to seal the two side sealing plates 10. An intelligent monitoring system is installed on the top of the ball valve body 1. Sealing mechanisms are provided between the two side sealing plates 10 and the sealing ball seat 22 inside the ball valve body 1. An adjustment mechanism is provided at the bottom of the connecting shaft 21 inside and at the top of the sealing ball seat 22. A ball seat outlet 24 is opened at the bottom of the sealing ball seat 22 and is connected to the bottom water inlet fixing plate 11. A ball seat inlet 23 is opened on one side of the sealing ball seat 22 and is connected to the ball seat outlet 24, and is used to connect the two water outlet fixing plates 3.

[0032] During use, the operator rotates the control wrench 20 to rotate the connecting shaft 21. The connecting shaft 21 synchronously drives the sealing ball seat 22 inside the square chamber to rotate synchronously. By switching the positions of the ball seat inlet 23 and the ball seat outlet 24, the water flow control between the bottom inlet fixing plate 11 and the two side outlet fixing plates 3 is achieved. At the same time, the built-in sealing mechanism ensures the sealing performance, and the sealing force is adjusted by the adjustment mechanism. Combined with the top intelligent monitoring system, full-condition monitoring is completed. Through the square integrated main structure design, the fit of each assembly component and the overall structure are improved. It integrates multiple functions such as water flow control, sealing protection, force adjustment, and intelligent monitoring. The equipment has a compact structure and strong stability, effectively solving the problems of loose structure, single function, and poor adaptability of traditional ball valves, and greatly improving the overall operational reliability of the equipment.

[0033] Specifically, the sealing mechanism includes a sealing ring 4 that is engaged with the inner side of the water outlet fixing plate 3. One side of the sealing ring 4 is tightly fitted with the sealing ball seat 22. It is used to seal the connection surface when the ball seat inlet 23 is connected to the connecting threaded cylinder 30 to prevent water leakage, and to prevent water from entering the interior of the water outlet fixing plate 3 when the ball seat inlet 23 is not connected to the connecting threaded cylinder 30.

[0034] During use, when the sealing ball seat 22 rotates to the water-connecting position, the ball seat inlet 23 and the connecting threaded cylinder 30 are interconnected, and the sealing ring 4 tightly fits the connecting gap, preventing water leakage. When the ball valve switches to the closed water-stopping position, the sealing ring 4 continuously prevents water from entering the interior of the outlet fixing plate 3, avoiding water accumulation and seepage problems. Through the targeted and fitted sealing ring structure, the sealing protection requirements of the ball valve in both water-connecting and water-stopping working states are fully covered, accurately sealing water leakage channels, effectively improving the overall sealing performance of the ball valve, eliminating leaks and water accumulation, and ensuring the standardization and stability of pipeline water supply operations.

[0035] Specifically, a connecting ring 45 is slidably disposed inside the connecting threaded cylinder 30. One side of the connecting ring 45 is fixedly connected to the sealing ring 4. Multiple compression springs 44 are fixedly disposed on the side of the connecting ring 45 away from the sealing ring 4, and a compression plate 43 is fixedly connected to the multiple compression springs 44. The compression plate 43 is slidably disposed inside the water outlet fixed plate 3 and is used to compress the sealing ring 4 into contact with the sealing ball seat 22 to increase the sealing force. A connecting plate 42 is fixedly disposed on the top of the compression plate 43. The connecting plate 42 is slidably disposed on the top inner side of the water outlet fixed plate 3 and is connected to the adjustment mechanism to control the compression force of the compression plate 43 on the sealing ring 4 when the connecting shaft 21 rotates, thereby reducing the friction between the sealing ring 4 and the sealing ball seat 22 while ensuring a seal.

[0036] During use, the adjusting mechanism drives the connecting plate 42 to slide, which in turn drives the squeezing plate 43 to slide inside the outlet fixing plate 3. Combined with the elastic deformation characteristics of the squeezing spring 44, this drives the connecting ring 45 to push and pull the sealing ring 4, dynamically adjusting the squeezing force between the sealing ring 4 and the sealing ball seat 22. Under water flow conditions, the squeezing force is increased to enhance the sealing effect, while under water cut-off conditions, the squeezing force is reduced to decrease component friction. Through this elastic linkage adjustment structure, the limitations of the fixed sealing force of traditional ball valves are broken, enabling dynamic adjustment of the sealing force. While fully ensuring the sealing effect, it minimizes ineffective frictional wear of the sealing components, effectively extending the service life of the sealing assembly and reducing equipment maintenance costs.

[0037] Specifically, the adjustment mechanism includes an adjustment plate 25 fixedly sleeved on the outside of the connecting shaft 21. The adjustment plate 25 is located on the top side inside the ball valve body 1 and at the top of the connecting shaft 21. A symmetrical concave quadrilateral groove 26 is opened on the outer side of the top of the adjustment plate 25. A rotating seat 46 is slidably arranged inside the concave quadrilateral groove 26. A transmission plate 41 is fixedly arranged on the top of the rotating seat 46. One side of the transmission plate 41 is fixedly connected to the connecting plate 42. It is used to drive the adjustment plate 25 to rotate when the connecting shaft 21 drives it. The rotating seat 46 repeatedly slides along the arc inside the concave quadrilateral groove 26, pulling the connecting plate 42 and the extrusion plate 43 to extrude the sealing ring 4. The extrusion force is greatest when the ball seat inlet 23 is connected to the connecting threaded cylinder 30, and decreases otherwise.

[0038] In use, the connecting shaft 21 rotates synchronously with the control wrench 20, driving the outer adjusting plate 25 to rotate. The concave quadrilateral groove 26 on the top of the adjusting plate 25 rotates synchronously, causing the rotating seat 46 inside the groove to slide back and forth along an arc trajectory. This, in turn, drives the transmission plate 41 and the connecting plate 42 to move in linkage, precisely controlling the extrusion stroke of the extrusion plate 43, and achieving adaptive adjustment for pressurization and sealing in the water-connected state and pressure reduction and energy saving in the water-disconnected state. Through the linkage structure of the arc sliding transmission, the on / off state of the ball valve and the sealing force are precisely matched. The adjustment response is fast and the control accuracy is high. Adaptive regulation can be completed without manual intervention, greatly improving the automation and intelligent operation level of the equipment.

[0039] Specifically, two fixing brackets 31 are fixedly installed on one side of the water outlet fixing plate 3. A sliding rod 32 is fixedly connected between one side of the two fixing brackets 31 and the water outlet fixing plate 3. A sliding block 40 is fixedly installed on the top of the transmission plate 41. The sliding block 40 is movably sleeved on the outside of the two sliding rods 32 to limit the movement of the transmission plate 41.

[0040] During use, when the transmission plate 41 is adjusted by reciprocating, the top sliding block 40 can slide smoothly along the outside of the slide rod 32. Relying on the limiting track formed by the fixed frame 31 and the slide rod 32, the movement trajectory and range of motion of the transmission plate 41 are strictly constrained, avoiding problems such as deviation, shaking, and misalignment during transmission. Through the constraint and protection of the limiting guide structure, the entire transmission and adjustment process is ensured to be smooth and regular, effectively improving the accuracy and stability of the sealing force adjustment, eliminating faults such as sealing failure and adjustment jamming caused by abnormal transmission, and ensuring long-term high-frequency stable operation of the equipment.

[0041] Specifically, the intelligent monitoring system includes a flow monitoring module, a pressure monitoring module, a data processing module, and a wireless transmission module. The intelligent monitoring system is fixedly mounted on the top of the ball valve body 1 and wrapped around the outside of the fixed seat 2. The intelligent monitoring system establishes electrical connections with the water flow path, sealing mechanism, and regulating mechanism inside the ball valve body 1, respectively, to monitor the water flow conditions inside the square chamber, the sealing status of the sealing ring 4, and the operating conditions of the regulating mechanism in all directions in real time.

[0042] During operation, the various functional modules of the intelligent monitoring system work collaboratively. The flow and pressure modules collect water flow and pressure data respectively, simultaneously monitoring the operating status of the sealing and regulating mechanisms. All collected data is transmitted to the data processing module for integration and analysis, while the wireless transmission module enables remote data transmission and storage. Through this multi-module integrated, comprehensive monitoring system, the system achieves full coverage monitoring of the ball valve's water flow conditions, sealing status, and mechanical operating status, completely overcoming the shortcomings of traditional ball valves that lack autonomous monitoring capabilities. It can capture various potential faults in real time, significantly improving the safety and controllability of equipment operation.

[0043] Specifically, the flow monitoring module is fixedly installed inside the water inlet passage of the bottom water inlet fixing plate 11. The flow monitoring module is set at the water inlet connection position corresponding to the ball seat outlet 24. It is used to collect the water flow data flowing into the sealed ball seat 22 through the bottom water inlet fixing plate 11 in real time, and transmit the collected flow data to the data processing module in real time to complete the summary analysis.

[0044] During operation, as water flows from the bottom inlet fixing plate 11 into the sealing ball seat 22, the flow monitoring module captures the dynamic changes in the inlet flow rate in real time, continuously collecting accurate flow data and simultaneously transmitting it to the data processing module for statistics, aggregation, and analysis. By deploying monitoring modules at key inlet points, the actual flow conditions at the ball valve inlet can be accurately obtained, providing precise data support for equipment condition judgment, fault identification, and intelligent linkage control. It can quickly identify abnormal problems such as flow interruption and sudden increases or decreases in flow, thus improving the dimensions of equipment condition monitoring.

[0045] Specifically, the pressure monitoring module is symmetrically installed on the inner wall of the two outlet fixing plates 3. The pressure monitoring module is arranged close to the sealing area between the sealing ring 4 and the sealing ball seat 22. It is used to detect the water pressure value of the internal cavity of the outlet fixing plate 3 in real time. By the fluctuation of the real-time water pressure value, it is determined whether there is a water leakage fault between the sealing ring 4 and the sealing ball seat 22. At the same time, the collected water pressure data is transmitted to the data processing module in real time.

[0046] During operation, the pressure monitoring module continuously collects water pressure data from the surrounding chambers of the sealing area, monitoring minute fluctuations in water pressure in real time. If an anomaly in water pressure occurs due to leakage from the sealing gap, the module can quickly detect it and upload the data to the data processing module. By deploying monitoring points close to the core sealing area, the accuracy of identifying sealing leakage faults is significantly improved. This allows for early detection of minor leaks, preventing small issues from escalating into large-scale leaks, and enabling early detection and warning of sealing faults, effectively enhancing the stability of the equipment's sealing operation.

[0047] Specifically, the intelligent monitoring system also includes an audible and visual early warning module. The audible and visual early warning module is fixedly installed on the top outer side of the fixed base 2 and located on the side of the control wrench 20. The audible and visual early warning module is electrically connected to the data processing module. When the data processing module detects that the flow data and water pressure data exceed the preset normal value range, it triggers the audible and visual early warning module to start the audible and visual early warning prompt, thereby reminding the equipment operator that there are faults such as abnormal water flow or sealing leakage in the ball valve.

[0048] During operation, the data processing module compares and analyzes the collected flow and water pressure data with preset standard values ​​in real time. When the data exceeds the normal range and a fault is detected in the equipment, the audible and visual warning module is immediately triggered, issuing a warning through both light and sound signals. This visual and audible proactive warning function solves the problem of traditional ball valve faults being hidden and difficult to detect. It can immediately alert operators to troubleshoot the fault, significantly shortening the fault handling time and reducing equipment wear and water supply losses caused by continuous operation during faulty operation.

[0049] Specifically, the data processing module has a built-in data storage unit and a working condition linkage control unit. The data storage unit is used to continuously store all working condition data collected by the flow monitoring module and the pressure monitoring module. The working condition linkage control unit is electrically connected to the regulating mechanism and is used to match the rotation amplitude of the regulating plate 25 according to the real-time monitored water flow rate and chamber water pressure data, so as to accurately assist in adjusting the squeezing force of the squeezing plate 43 on the sealing ring 4 and adapt to the sealing operation requirements under different water flow conditions.

[0050] During use, the data storage unit continuously retains all operating condition monitoring data, enabling long-term data archiving and traceability. The operating condition linkage control unit intelligently analyzes the sealing requirements of the current operating condition based on real-time flow and water pressure data, and dynamically adjusts the compression force of the sealing ring 4 according to the rotation amplitude of the regulating plate 25. Through data storage and intelligent linkage control functions, not only is the traceability of equipment operation and maintenance data achieved, facilitating subsequent equipment maintenance and operating condition review, but also the adaptive matching of sealing force and operating conditions is completed, allowing the ball valve to adapt to various differentiated water flow conditions. This completely solves the problem of poor operating condition adaptability of traditional ball valves, and comprehensively improves the intelligent control capability and versatility of the equipment.
