Description

Technical Field

[0001] This invention relates to the field of ball valve technology, specifically to a multifunctional ball valve suitable for complex fluid media. Background Technology

[0002] In traditional fluid transport operations, the operation and management of ball valves has long remained at a rather rudimentary stage. When operators use control equipment to perform ball valve opening and closing tasks, they rely entirely on established standard operating procedures. After the operation is completed, they simply assume that the ball valve has completed the expected action. This approach completely ignores the complex impact of differences in fluid properties under actual working conditions. With the development of industry, more and more production scenarios involve the transport of high-viscosity fluids, such as crude oil extraction and transportation, high-viscosity material processing in fine chemicals, and the processing of high-concentration sauces in the food industry. Due to their unique physical properties, high-viscosity fluids can cause many problems when flowing through ball valves. The strong cohesive forces between their molecules lead to a great deal of friction between the ball, valve stem, and sealing surface inside the ball valve, which translates into additional torque requirements for the motor and its transmission mechanism.

[0003] Under current technological conditions, there are serious loopholes in the monitoring of ball valve operation. After operators complete the prescribed actions of closing or opening the ball valve on the control equipment, there is no corresponding means to confirm the actual status of the ball valve; it is impossible to monitor in real time whether the motor output torque exceeds the load due to the influence of high viscosity fluid, nor is it possible to know whether the ball valve has actually completed the corresponding action; for example, in a large crude oil pipeline network, the staff of the remote control center operate the ball valves in various places according to the routine procedures, but due to the lack of effective torque and valve status monitoring feedback, they are completely unaware whether the ball valves in the pipeline have failed to open or close normally due to the high viscosity of crude oil;

[0004] The lack of the aforementioned monitoring methods has led to a series of serious consequences for fluid transportation operations. If a ball valve fails to open properly, the fluid transportation channel is instantly blocked, forcing the entire production process to halt and severely impacting business operations. For example, in an oil refinery, if a ball valve on a feedstock pipeline cannot open due to high-viscosity crude oil, subsequent refining processes will be completely shut down due to a lack of raw materials, resulting in huge economic losses. If a ball valve fails to close properly, leakage of high-viscosity fluid not only wastes materials but also pollutes the surrounding environment. In the case of transporting flammable and explosive fluids, it can even trigger catastrophic safety accidents. Prolonged exposure to this abnormal state causes the ball valve and its actuator to withstand pressures far exceeding their design load, accelerating equipment wear, significantly shortening service life, and drastically increasing equipment maintenance costs, seriously threatening the long-term stable production of the enterprise.

[0005] Furthermore, in the field of industrial fluid transportation, ball valves are key control devices. However, under the existing technology system, there are significant technical bottlenecks in the monitoring methods for ball valve sealing failure. In terms of mechanical structure deformation, traditional monitoring relies solely on manual periodic inspections, which cannot capture in real time the microscopic changes in valve body bolt stress relaxation, ball elastic deformation, and valve stem bending. Ball valves that have been used for a certain number of years exhibit valve body bolt stress decay, but existing vibration sensors or pressure transmitters cannot accurately identify the correlation between bolt preload changes and sealing surface fit.

[0006] Meanwhile, dynamic wear monitoring also has technical blind spots. Although the current mainstream ultrasonic thickness gauges can detect valve body wall thickness, they lack effective means to monitor changes in the micro-roughness of the sealing surface and the formation process of annular indentations. In slurry conveying systems, the wear rate of ball valve sealing surfaces far exceeds expectations, and traditional monitoring cycle settings often lag behind the actual wear process, resulting in serious delays in preventive maintenance.

[0007] The impact of environmental factors further highlights the vulnerability of existing monitoring systems. For example, monitoring valve seat shrinkage and deformation under low-temperature conditions is crucial. In ball valves, failure to detect low-temperature seat shrinkage in time leads to significant radial clearance after a period of operation in extreme environments, ultimately causing media leakage accidents. Furthermore, the issue of material thermal expansion differences caused by alternating temperature cycles is addressed by existing thermal imagers, which can only detect surface temperature and cannot quantify changes in internal stress distribution.

[0008] Therefore, this invention proposes a multifunctional ball valve suitable for complex fluid media to solve the above problems. Summary of the Invention

[0009] In view of this, the technical problem to be solved by the present invention is to propose a multifunctional ball valve suitable for complex fluid media, so as to solve the problems existing in the prior art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional ball valve suitable for complex fluid media, comprising: a valve body, a ball valve, a flow port, a valve stem, a vertical cavity component, and a drive mechanism; and further comprising: an effective operation feedback component;

[0011] The effective operation feedback component includes a support ring fixedly connected to the inner cavity of the vertical cavity component. A rotating column is provided inside the vertical cavity component. A limiting groove A is formed on the rotating column. The rotating column is rotatably connected to the support ring through the limiting groove A.

[0012] The rotating column is provided with an arc-shaped groove, and the inner wall of the vertical cavity component is symmetrically and fixedly connected with guide rails. An upward moving component is slidably connected to the guide rails, and the upward moving component is sleeved on the rotating column.

[0013] A column rod is fixedly connected to the inner wall of the upper moving part, and the column rod is slidably disposed in the arc-shaped groove.

[0014] The top of the moving part is fixedly connected to a covering body, and a group of strain gauges A are fixedly connected at equal intervals on the covering body.

[0015] Preferably, the flow port is provided on the ball valve, and the ball valve is located in the valve body. The valve stem is fixedly connected to the top of the ball valve, the vertical cavity component is fixedly connected to the valve body, and the drive mechanism is located at the upper end of the vertical cavity component.

[0016] Preferably, it also includes a ball valve intelligent blind-spot monitoring component located below the effective operation feedback component;

[0017] The ball valve intelligent sensing blind-spot-free monitoring component includes a first auxiliary ring and a second auxiliary ring fixedly connected to the inner wall of the valve body; the first auxiliary ring and the second auxiliary ring are distributed on both sides of the ball valve.

[0018] Preferably, the valve body has a mounting groove, and a sealing gasket is attached to the mounting groove. The ball valve, the inner wall of the valve body, and the first and second auxiliary rings constitute a temporary liquid storage tank.

[0019] Preferably, the bottom of the vertical cavity component is symmetrically and fixedly connected with protruding guide posts.

[0020] Preferably, an I-beam is slidably connected in the placement groove, the bottom surface of the I-beam is symmetrically provided with a surging groove, and a limiting groove B is provided on the I-beam.

[0021] Preferably, strain gauges B are fixedly connected at equal intervals to the bottom surface of the rotating column.

[0022] Compared with the prior art, the present invention provides a multifunctional ball valve suitable for complex fluid media, which has the following advantages:

[0023] 1. The effective operation feedback component in this invention, by monitoring the rotation angle of the ball valve fixedly connected to the valve stem, can bring the following benefits to the overall operation:

[0024] Real-time status feedback ensures operational accuracy: Previously, after operators completed operations on the control equipment, they could not determine whether the ball valve had actually completed its action; this component can provide real-time feedback to the operator on whether the ball valve's rotation angle is in a normal state, allowing them to know the actual open or closed status of the ball valve immediately, avoiding a series of subsequent problems caused by misjudgment; for example, in complex chemical production pipeline networks, operators can quickly confirm whether the ball valve in the valve body has acted according to the instructions based on the feedback, ensuring the continuity of the production process;

[0025] Precise fault location: If the ball valve does not operate as expected, maintenance personnel can quickly determine the problem by using the rotation angle data. If the angle does not reach the set fully open or fully closed value, the fault can be accurately located in the ball valve itself, rather than blindly checking the entire conveying system, which greatly improves the efficiency of fault diagnosis.

[0026] 2. While monitoring the valve stem rotation angle through the effective operation feedback component, the rotating column, the upward-moving component, and the covering body of this invention also offer the following benefits:

[0027] Enhancing structural stability and resisting external deformation: During the transportation of complex fluid media, the valve stem is highly susceptible to impact forces, frictional forces, and abnormal torque caused by the characteristics of the medium. When the valve stem drives the ball valve to rotate to block the fluid, the rotation of the rotating column fixedly connected to the valve stem causes the upward moving part and the covering body to move vertically and be fitted onto the valve stem. This is equivalent to adding an extra support structure to the valve stem. Taking the transportation of high-viscosity fluids containing solid particles as an example, the frequent impact of the particles on the valve stem can cause the valve stem to bend and deform. At this time, the covering body is tightly fitted onto the valve stem, which can effectively disperse these impact forces, allowing the valve stem to maintain its original shape when facing strong external forces. This greatly enhances the structural stability of the valve stem and avoids the normal opening and closing and sealing performance of the ball valve due to deformation.

[0028] Reducing stress concentration: During operation, uneven stress distribution can cause stress concentration in certain parts of the valve stem, a common cause of valve stem damage. The upward-moving component and the covering in the effective operation feedback assembly function during valve stem rotation, reducing stress concentration points by altering the force distribution on the valve stem. For example, under high pressure differential conditions, the upward-moving component and the covering on the valve stem can evenly distribute stress, extending the valve stem's fatigue life, reducing the generation and propagation of cracks caused by stress concentration, and thus improving the overall reliability and durability of the valve stem.

[0029] Optimizing valve performance and ensuring precise rotation: Deformation of the valve stem directly affects the accuracy of ball valve rotation, thus impacting the valve's sealing effect on the fluid medium. This component enhances the strength of the valve stem, making it more stable during rotation and enabling precise rotation of the ball valve to the predetermined position. In chemical production, extremely high precision is required for fluid flow and shut-off control. Precise valve stem rotation ensures accurate opening and closing of the ball valve, achieving precise fluid control, avoiding inaccurate valve opening due to valve stem deformation, and guaranteeing the stability of the production process and the consistency of product quality.

[0030] 3. This invention, through the design of a ball valve intelligent sensing and blind-spot-free monitoring component, can bring the following benefits to the overall operation:

[0031] Preventing leaks caused by displacement and wear: By indirectly monitoring ball valve displacement and wear, the system can anticipate the risk of decreased ball valve sealing performance. Detecting a change in ball valve position indicates loose components or mechanical deformation, which can affect the fit between the ball valve and the first and second auxiliary rings, potentially leading to leaks. For example, in harsh conditions such as slurry transport, it can promptly detect changes in the micro-roughness of the sealing surface and the formation of annular indentations. Before wear becomes severe enough to cause leaks, it alerts the company to perform maintenance or replace components, effectively preventing leaks and ensuring the safe and stable operation of industrial production.

[0032] Overcoming the problem of delayed monitoring cycles in traditional methods: Traditional monitoring methods rely on manual periodic inspections and limited testing equipment, making it impossible to track the status of ball valves in real time. The monitoring cycle often lags behind the actual wear process. This monitoring component can monitor the displacement and wear of ball valves in real time, improving operational safety and timely detection of potential leaks. It can accurately grasp both microscopic changes in the sealing surfaces of the ball valve and the first and second auxiliary rings, as well as the displacement of the entire component, detecting whether there is fluid leakage in the valve in real time. Once a leak is detected, an early warning can be issued immediately through an external display device connected to strain gauge group B. For example, in petrochemical enterprises, where the transported crude oil and chemical raw materials are flammable, the component can detect leaks in the early stages of ball valve problems, allowing staff to take rapid measures, such as emergency shutdown of related equipment and emergency repairs, to prevent the leak from spreading and avoid catastrophic accidents such as fires and explosions. This ensures the safety of personnel and the surrounding environment at the production site, shifting from passive maintenance to proactive prevention, greatly improving the timeliness and effectiveness of equipment maintenance.

[0033] 4. The present invention, by adding a temporary liquid storage tank to the ball valve intelligent sensing blind-spot-free monitoring component, has the following advantages:

[0034] Preventing accidents caused by fluid leakage: When gaps appear on the sealing surface of the ball valve due to displacement or wear, the temporary reservoir can work with the second auxiliary ring to collect the leaked fluid medium in a timely manner, preventing it from continuing to flow and leak into the surrounding environment within the valve body. This is especially important when conveying flammable, explosive, toxic, harmful, or corrosive fluids, and can effectively prevent safety accidents such as fires, explosions, poisoning, and environmental pollution caused by fluid leakage, ensuring the safety of personnel and the normal operation of the enterprise.

[0035] Facilitates leak detection: The temporary storage tank collects leaked fluid, making leaks easier to detect. Even small leaks will accumulate in the temporary storage tank. By regularly inspecting the tank or installing appropriate level monitoring devices, staff can promptly detect leaks in ball valves. Compared to traditional methods, this allows for faster detection of seal failures, saving time for subsequent maintenance and repairs. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0053] Example

[0054] Please refer to Figures 1 to 5 , Figure 11 As shown:

[0055] To address the problems mentioned in the technical solutions, this application provides a multifunctional ball valve suitable for complex fluid media, comprising: a valve body 1, a ball valve 2, a flow port 201, a valve stem 3, a vertical cavity component 4, and a drive mechanism 5; the flow port 201 is opened through the ball valve 2, and the ball valve 2 is located in the valve body 1; the valve stem 3 is fixedly connected to the top of the ball valve 2; the vertical cavity component 4 is fixedly connected to the valve body 1; the drive mechanism 5 is disposed at the upper end of the vertical cavity component 4; and further comprising: an effective operation feedback component 6 and a ball valve intelligent sensing blind-spot-free monitoring component 7, the ball valve intelligent sensing blind-spot-free monitoring component 7 being located below the effective operation feedback component 6;

[0056] The effective operation feedback component 6 is used to prevent the valve body 1 from being incompletely opened and closed due to torque or friction on the valve stem 3 caused by fluid viscosity issues in the ball valve 2. The effective operation feedback component 6 includes a support ring 601 fixedly connected to the inner cavity of the vertical cavity component 4. A rotating column 602 is disposed within the vertical cavity component 4, and a limiting groove A603 is formed on the rotating column 602. The rotating column 602 is rotatably connected to the support ring 601 through the limiting groove A603. An arc-shaped groove 604 is provided on the column 602. A guide rail 605 is symmetrically fixedly connected to the inner wall of the vertical cavity component 4. An upward moving part 606 is slidably connected to the guide rail 605. The upward moving part 606 is sleeved on the rotating column 602. A column rod 607 is fixedly connected to the inner wall of the upward moving part 606. The column rod 607 is slidably disposed in the arc-shaped groove 604. A covering body 608 is fixedly connected to the top of the upward moving part 606. Strain gauge A group 609 is fixedly connected at equal intervals on the covering body 608.

[0057] in:

[0058] The flow port 201 is used for the flow of fluid medium through the inside of the valve body 1.

[0059] The drive mechanism 5 is used to control the rotation of the valve stem 3, thereby enabling the ball valve 2 to rotate within the valve body 1 and thus opening or closing the valve body 1.

[0060] The effective operation feedback component 6 is used to avoid the problem of incomplete opening and closing of the valve body 1 caused by torque or friction on the valve stem 3 due to fluid viscosity issues in the ball valve 2.

[0061] Two support rings 601 are symmetrically arranged to fit the limiting groove A603 on the rotating column 602, thereby providing rotation for the rotating column 602.

[0062] The upper moving part 606 has a lateral groove that is adapted to the guide rail 605.

[0063] The column rod 607 is slidably adapted to the limiting groove A603.

[0064] The covering body 608 can be used to guide the movement of the moving part 606, and can also help the rotating column 602 and the moving part 606 to be stably covered on the valve stem 3 to enhance their structural stability.

[0065] There are two sets of effective operation feedback components 6, which are symmetrically arranged on the valve stem 3. When the two symmetrical strain gauges A group 609 come into contact and have a certain squeezing action, the external display device that is electrically connected to them will feed back the stress values ​​of the two strain gauges A group 609. If the values ​​are consistent with the values ​​under normal working conditions where the ball valve 2 can completely seal the valve body 1, it can be indirectly indicated that the valve stem 3 rotates at this time to complete the expected work requirements, that is, the closing action of the ball valve 2 on the valve body 1 has been completed.

[0066] A further embodiment: Please refer to Figures 1 to 3 , Figures 6 to 10 As shown:

[0067] The ball valve intelligent sensing blind-spot-free monitoring component 7 is used to monitor in real time whether there is a fluid leakage gap between the ball valve 2 and the inner wall of the valve body 1 due to external installation, wear, and environmental temperature issues. This ensures effective fluid cutoff and avoids fluid leakage. The ball valve intelligent sensing blind-spot-free monitoring component 7 includes a first auxiliary ring 701 and a second auxiliary ring 702 fixedly connected to the inner wall of the valve body 1. The first auxiliary ring 701 and the second auxiliary ring 702 are distributed on both sides of the ball valve 2, and a mounting groove 70 is provided on the valve body 1. 3. A sealing gasket 704 is attached inside the placement groove 703. The ball valve 2, the inner wall of the valve body 1, and the first auxiliary ring 701 and the second auxiliary ring 702 form a temporary liquid storage groove 705. The bottom of the vertical cavity component 4 is symmetrically fixedly connected with an outwardly protruding guide post 706. An I-beam component 707 is slidably connected inside the placement groove 703. A surging groove 708 is symmetrically opened on the bottom surface of the I-beam component 707. A limit groove B709 is opened on the I-beam component 707. Strain gauges B group 710 are fixedly connected at equal intervals on the bottom surface of the rotating column 602.

[0068] in:

[0069] The ball valve intelligent sensing blind spot monitoring component 7 is used to monitor in real time the situation where the ball valve 2 has fluid leakage gaps between its own position and the inner wall of the valve body 1 due to external installation, wear and tear and environmental temperature issues, so as to ensure effective cut-off of fluid and avoid fluid leakage.

[0070] Because the first secondary ring 701 is located at the first point through which the fluid passes, the impact on the first secondary ring 701 is greater than the impact on the second secondary ring 702.

[0071] When ball valve 2 wears down or its position within valve body 1 changes, fluid can enter temporary reservoir 705 through the gap between the first auxiliary ring 701 and ball valve 2, indicating that there is a problem with the valve's operation.

[0072] The fluid medium flowing into the temporary storage tank 705 will push the I-beam 707 upward through the surging channel 708.

[0073] The limiting groove B709 is compatible with the outwardly protruding guide post 706.

[0074] When a problem occurs with ball valve 2 or the first auxiliary ring 701, i.e., there is a gap between ball valve 2 and the first auxiliary ring 701 causing poor sealing, the I-beam 707, pushed by the fluid medium, will move upward and eventually contact and compress the strain gauge group B 710. At this time, the external display device that is electrically connected to the strain gauge group B 710 will report the change in the strain gauge pressure value in the strain gauge group B 710, thereby informing relevant personnel that there is a sealing problem with the pipeline valve.

[0075] The working principle of all the content in the above embodiments is as follows:

[0076] In the initial state:

[0077] The flow port 201 on the ball valve 2 coincides with the fluid medium flow pipeline of the valve body 1, that is, the fluid medium in the valve body 1 can continue to flow in the valve body 1 through the flow port 201. The column rod 607 is located at the bottom of the arc groove 604. The two sets of strain gauges A group 609 arranged symmetrically do not contact each other. The I-beam 707 does not move upward in the placement groove 703. There is no fluid medium in the temporary liquid storage tank 705.

[0078] The following is the working process of the validity operation feedback component 6:

[0079] Since there are two sets of known validity operation feedback components 6, and the working process is the same, only one of them will be described below;

[0080] In use, when the operator controls the valve stem 3 to rotate the ball valve 2 via the drive mechanism 5, thereby sealing the valve body 1, during this process, the rotating column 602, which is fixedly connected to the valve stem 3, will rotate with the support ring 601 and the assistance of the limiting groove A603 on it. (See attached diagram.) Figure 4 During the rotation of the rotating column 602, the upper moving part 606 moves upward with the assistance of the upper column rod 607 and the arc-shaped groove 604 opened on the rotating column 602, guided by the guide rail 605. As the upper moving part 606 moves upward, the length of the assembly composed of the rotating column 602 and the upper moving part 606 will increase. During this process, the covering body 608 on the top of the upper moving part 606 will also move with the strain gauge A group 609 on it. Furthermore, since there are two sets of known effective operation feedback components 6, which are symmetrically arranged on the valve stem 3, when the two symmetrical strain gauge A groups 609 come into contact and have a certain squeezing action, the external display device that has an electrical connection with it will feed back the stress values ​​of the two strain gauge A groups 609. If the value is consistent with the value under the normal working condition where the ball valve 2 can completely seal the valve body 1, it can be indirectly indicated that the rotation angle of the valve stem 3 has completed the expected work requirements, that is, the closing action of the ball valve 2 on the valve body 1 has been completed. Otherwise, there is a problem with the device components at this time.

[0081] Furthermore, the effective operation feedback component 6 monitors the rotation angle of the ball valve 2, which is fixedly connected to the valve stem 3, providing real-time status feedback on the valve stem 3 to ensure operational accuracy. Previously, after completing operations on the control equipment, operators could not determine whether the ball valve 2 had actually performed its action. This component can provide real-time feedback to the operator regarding the normal rotation angle of the ball valve 2, allowing them to immediately know the actual open or closed state of the ball valve 2 and avoid subsequent problems caused by misjudgment. For example, in complex chemical production pipeline networks, operators can quickly confirm whether the ball valve 2 in the valve body 1 has acted according to instructions based on the feedback, ensuring the continuity of the production process.

[0082] Precise fault location: If ball valve 2 fails to operate as expected, maintenance personnel can quickly determine the problem by using the rotation angle data; if the angle does not reach the set fully open or fully closed value, the fault can be precisely located in ball valve 2 itself, rather than blindly checking the entire conveying system, which greatly improves the efficiency of fault diagnosis.

[0083] Furthermore, while monitoring the rotation angle of the valve stem 3 through the effective operation feedback component 6, the rotating column 602, the upward moving part 606, and the covering body 608 can also enhance structural stability and resist external deformation. During the transportation of complex fluid media, the valve stem 3 is easily subjected to impact forces, friction forces, and abnormal torque caused by the characteristics of the medium. When the valve stem 3 drives the ball valve 2 to rotate to block the fluid, the rotation of the rotating column 602, which is fixedly connected to the valve stem 3, can cause the upward moving part 606 and the covering body 608 to move vertically and be fitted onto the valve stem 3. This is equivalent to adding an extra support structure to the valve stem 3. Taking the transportation of high-viscosity fluid containing solid particles as an example, the frequent impact of the particles on the valve stem 3 will cause the valve stem 3 to bend and deform. At this time, the covering body 608 is tightly fitted onto the valve stem 3, which can effectively disperse these impact forces, so that the valve stem 3 can maintain its original shape when facing strong external forces, greatly enhancing the structural stability of the valve stem 3 and avoiding the normal opening and closing and sealing performance of the ball valve 2 due to deformation.

[0084] Reducing stress concentration: During operation, uneven stress distribution can cause stress concentration in certain parts of the valve stem 3, which is a common cause of valve stem 3 damage. The upward-moving component 606 and the covering body 608 in the effective operation feedback assembly 6 function during the rotation of the valve stem 3. By changing the force distribution of the valve stem 3, they reduce the stress value at stress concentration points. For example, under high pressure differential conditions, the upward-moving component 606 and the covering body 608 fitted on the valve stem 3 can evenly distribute the stress, extend the fatigue life of the valve stem 3, reduce the generation and propagation of cracks caused by stress concentration, and thus improve the overall reliability and durability of the valve stem 3.

[0085] Optimizing valve performance and ensuring precise rotation: Deformation of the valve stem 3 directly affects the accuracy of the ball valve 2's rotation, thus impacting the valve's sealing effect on the fluid medium. This component enhances the strength of the valve stem 3, making it more stable during rotation and enabling it to precisely rotate the ball valve 2 to the predetermined position. In chemical production, extremely high precision is required for fluid flow and shut-off control. The precise rotation of the valve stem 3 ensures that the ball valve 2 can open and close accurately, achieving precise fluid control and preventing inaccurate valve opening due to valve stem 3 deformation, thus guaranteeing the stability of the production process and the consistency of product quality.

[0086] Please refer to the above work process. Figures 1 to 5 , Figure 11 .

[0087] The following is the working process of the ball valve intelligent blind-spot-free monitoring component 7:

[0088] During use, if ball valve 2 becomes misaligned or wears down, a gap will appear at the contact surface between ball valve 2 and the first auxiliary ring 701. The fluid medium will then enter the temporary storage tank 705 through this gap. As the fluid medium continues to enter, it flows into the surging groove 708 at the bottom of the I-beam 707, thus lifting the I-beam 707 upwards. At this time, the sealing gasket 704 remains in normal sealing operation, but the I-beam 707 will move upwards in the placement groove 703, thereby compressing the strain gauge group B 710 at the bottom of the rotating column 602, further... As is known, when a problem occurs with ball valve 2 or the first auxiliary ring 701, i.e., when there is a gap between ball valve 2 and the first auxiliary ring 701 causing poor sealing, the I-beam 707, pushed by the fluid medium, will move upward and eventually contact and compress strain gauge group B 710. At this time, the external display device, which is electrically connected to strain gauge group B 710, will provide feedback on the change in the strain gauge pressure value in strain gauge group B 710, thereby informing relevant personnel that there is a sealing problem with the pipeline valve. Thus, relevant personnel will carry out corresponding maintenance work based on the feedback from the external display device.

[0089] Furthermore, the design of the ball valve intelligent blind-spot-free monitoring component 7 effectively prevents leakage caused by ball valve 2 displacement and wear. Through indirect monitoring of ball valve 2 displacement and wear, the component can predict the risk of decreased sealing performance of ball valve 2 in advance. When a change in the position of ball valve 2 is detected, it means that there are problems with loose parts or deformation of the mechanical structure, which may affect the fit between ball valve 2 and the sealing surfaces of the first auxiliary ring 701 and the second auxiliary ring 702, causing leakage. For example, in harsh working conditions such as slurry transportation, it can promptly detect changes in the micro-roughness of the sealing surface and the formation of annular indentations, reminding the company to perform maintenance or replace parts before the wear becomes severe enough to cause leakage, effectively preventing leakage accidents and ensuring the safe and stable operation of industrial production.

[0090] Overcoming the problem of delayed monitoring cycles in traditional methods: Traditional monitoring methods rely on manual periodic inspections and limited testing equipment, making it impossible to track the status of ball valve 2 in real time. The monitoring cycle often lags behind the actual wear process. This monitoring component can monitor the displacement and wear of ball valve 2 in real time, improving operational safety and timely detection of potential leaks. It can accurately grasp both the microscopic changes of the sealing surfaces of ball valve 2 with the first and second auxiliary rings 701 and 702, as well as the displacement of the entire component, and detect whether there is fluid leakage in the valve in real time. Once a leak is detected, an early warning can be issued immediately through an external display device connected to strain gauge group B 710. For example, in petrochemical enterprises, the crude oil and chemical raw materials being transported are flammable. The component can detect leaks in the early stages of problems with ball valve 2, allowing staff to take rapid measures, such as emergency shutdown of related equipment and emergency repairs, to prevent the leak from spreading and avoid catastrophic accidents such as fires and explosions. This ensures the safety of personnel and the surrounding environment at the production site, transforming passive maintenance into proactive prevention, and greatly improving the timeliness and effectiveness of equipment maintenance.

[0091] Furthermore, by adding a temporary liquid storage tank 705 to the ball valve intelligent blind-spot-free monitoring component 7, accidents caused by fluid leakage can be effectively prevented. When gaps appear on the sealing surface of the ball valve 2 due to displacement or wear, the temporary liquid storage tank 705 can work with the second auxiliary ring 702 to collect the leaked fluid medium in a timely manner, preventing it from continuing to flow and leak into the surrounding environment within the valve body 1. This is especially important when conveying flammable, explosive, toxic, harmful, or corrosive fluids, and can effectively prevent safety accidents such as fires, explosions, poisoning, and environmental pollution caused by fluid leakage, ensuring the safety of personnel and the normal operation of the enterprise.

[0092] Facilitates leak detection: The temporary reservoir 705 collects leaked fluid, making leaks easier to detect. Even small leaks will accumulate in the temporary reservoir 705. By regularly inspecting the temporary reservoir 705 or installing appropriate level monitoring devices, staff can promptly detect leaks in ball valve 2. Compared to traditional methods, this allows for faster detection of seal failures, saving time for subsequent maintenance and repairs.
