Description

Technical Field

[0001] The present invention relates to the field of valve technology, in particular to a temperature-controlled ball valve capable of self-adapting to temperature differences. Background Art

[0002] In industrial production and various pipeline systems, gate valves play a key role in fluid shutoff and are widely used to control the flow and blockage of fluids. However, after long-term use, the valve stem of the gate valve often deforms, which has a serious impact on its normal operation and service life.

[0003] Numerous factors can cause valve stem deformation in pipeline systems. For one thing, when the pressure in the pipeline exceeds the normal range, forcing the gate valve closed by the operator can subject the valve stem to significant axial force. The instantaneous, powerful impact force generated by water hammer can also act on the valve stem, causing deformation. Furthermore, poor material quality, insufficient strength and rigidity, internal defects, misalignment during installation, and mechanical damage can all increase the risk of stem deformation during operation. Furthermore, the vibration environment of the ball valve can cause the valve stem to experience alternating stress due to resonance. Furthermore, corrosion and wear of the valve stem can lead to a continuous decrease in strength and rigidity, all of which are significant contributors to stem deformation.

[0004] It's worth noting that, under current technological conditions, there are no effective monitoring measures for valve stem deformation. Currently, most rely on regular manual inspections to detect signs of valve stem deformation. However, this method suffers from significant lag and fails to effectively understand the actual condition of the valve stem. Furthermore, it's difficult for humans to detect the initial signs of valve stem deformation, and by the time they're discovered, significant damage has already occurred to the pipeline system.

[0005] Furthermore, the media flow pipes and ball valves of the valve body are prone to various impurities such as oil, dust, and metal shavings. These impurities can come from a variety of sources, including welding slag and metal debris left over from pipeline installation; impurities carried by the fluid medium itself; or external dust and oil that intrudes into the piping system under harsh working conditions. Once these impurities accumulate in the valve body's flow pipes and ball valves, they increase friction during ball valve rotation. The mixture of oil and metal shavings forms a sticky layer of dirt at the contact points between the ball and valve seat, and between the valve stem and stuffing box. This layer, like sandpaper, hinders the smooth rotation of the ball, significantly increases operating torque, and can damage the drive unit.

[0006] Therefore, how to effectively solve the impact of impurity accumulation in the valve body medium circulation pipeline and ball valve on the rotation of the ball valve, and establish a complete monitoring and early warning system, has become a key issue in the current pipeline system maintenance and optimization.

[0007] Therefore, the present invention proposes a temperature-controlled ball valve that is self-adaptive to temperature differences to solve the above problems. Summary of the Invention

[0019] Preferably, a cylindrical through hole runs through the middle of the electromagnet A.

[0020] Preferably, a water-based cleaning liquid is provided in the cleaning liquid bag.

[0021] Compared with the prior art, the present invention provides a temperature-controlled ball valve that is self-adaptive to temperature differences, which has the following beneficial effects:

[0022] 1. The present invention, through the design of the deformation detection component, can bring many beneficial effects to the valve body with valve stem deformation detection, which are mainly reflected in the following aspects:

[0023] Ensure safe and stable operation of the system and provide early warning of faults: It can monitor the deformation of the valve stem in real time and issue a warning as soon as the valve stem begins to deform slightly, allowing staff to take measures in advance to avoid further aggravation of the valve stem deformation, which may lead to serious problems such as the ball valve being unable to open and close normally and fluid leakage, thereby ensuring the safe and stable operation of the entire pipeline system;

[0024] Prevent chain reactions: In complex industrial piping systems, a valve failure can trigger a series of chain reactions. By detecting valve stem deformation, problems can be discovered and addressed in a timely manner, preventing valve failures caused by valve stem deformation from spreading to other equipment and pipelines, avoiding larger-scale production accidents and economic losses.

[0025] Improve production efficiency and reduce downtime: Traditional methods that rely on regular manual inspections are difficult to detect early valve stem deformation problems, and repairs are often delayed until the problem becomes serious, resulting in long downtime. This design's deformation detection allows maintenance personnel to repair or replace the valve at the appropriate time, scheduling maintenance work in a planned manner, significantly reducing unexpected downtime caused by sudden valve stem failures, improving production equipment utilization, and ensuring production continuity.

[0026] Extend equipment life: By promptly detecting and addressing valve stem deformation problems, additional wear and damage to other valve components and the pipeline system caused by excessive valve stem deformation is avoided, thereby extending the service life of the valve and the entire pipeline system, reducing the frequency of equipment updates and replacements, and saving equipment investment costs.

[0027] 2. The present invention uses gas as the driving source of the sliding column. When detecting a situation where the valve stem is cracked but not deformed due to torsional force caused by water impact, it has many advantages:

[0028] High-sensitivity detection: Gas molecules are widely spaced and highly fluid, enabling rapid response to minute changes. Even if the valve stem has tiny cracks caused by torsional forces, gas can quickly leak through them, allowing inspectors to detect abnormalities promptly through indirect feedback from electrical contacts A and B. Compared to other detection methods, this method is more sensitive to initial tiny cracks, significantly improving detection accuracy.

[0029] Non-destructive testing characteristics: The gas is mild in nature and will not cause additional wear or damage to the valve stem like some physical testing methods, such as mechanical contact testing, nor will it cause chemical reactions like chemical testing methods. This ensures that the original performance and structural integrity of the valve stem will not be affected during the testing process, maintaining the normal working state of the valve stem;

[0030] Multi-dimensional detection supplement: Gas detection can detect cracks in the valve stem but not deformation, which complements the traditional detection method that focuses on valve stem deformation. It evaluates the health of the valve stem from different angles, provides richer information for a comprehensive understanding of the valve stem status, improves the entire detection system, and makes the detection results more valuable for reference.

[0031] 3. The present invention can bring many beneficial effects to the overall work through the provision of the valve maintenance assembly, which are mainly reflected in the following aspects:

[0032] Maintenance convenience and efficiency, no need to disassemble the valve body: Traditional valve body cleaning and maintenance often requires disassembly of the valve seat and the valve body, which not only consumes a lot of time and manpower, but also may damage the valve body due to improper operation during the disassembly process. The valve maintenance kit can be cleaned without disassembling the valve body, greatly saving maintenance time and cost and improving maintenance efficiency;

[0033] Fast cleaning: It can quickly and effectively deliver water-based cleaning liquid to the valve body flow pipe wall and ball valve surface, quickly deal with oil, dust and metal chips impurities, reduce the accumulation of impurities inside the valve body, shorten the time of single maintenance, and enable the valve body to be restored to good working condition more quickly;

[0034] Extend the service life of the valve body and reduce friction loss: By using water-based cleaning fluid to clean and lubricate the valve body circulation pipe wall and the ball valve surface, the friction coefficient between the ball valve and the circulation pipe wall during rotation can be effectively reduced, friction loss can be reduced, and component wear and deformation caused by long-term friction can be avoided, thereby extending the service life of the valve body; prevent impurity corrosion, and promptly remove oil, dust and metal chips inside the valve body to avoid chemical reactions between these impurities and the valve body material, prevent corrosion, and protect the structural integrity and performance stability of the valve body.

[0035] 4. The present invention, by designing the valve stem into a hollow structure, can bring many beneficial effects to the overall work, which are mainly reflected in the following aspects:

[0036] Improve heat dissipation performance: In some environments with high operating temperatures, the internal space of the hollow valve stem is conducive to air circulation, thereby enhancing the heat dissipation capacity of the valve stem, helping to reduce the operating temperature of the valve stem, preventing material performance degradation and seal aging caused by overheating, and improving the reliability and stability of the valve;

[0037] Optimized spatial layout: The hollow valve stem provides a testing space for deformation detection, making the detection methods flexible and diverse, optimizing the layout of the detection system so that the detection components are no longer randomly distributed outside the valve body, reducing the hidden dangers of failure caused by aging and wear of the lines, and facilitating maintenance and management. In addition, it reduces the detection cost and eliminates the need to design a complex external structure for detection, saving additional detection equipment and installation costs, improving the economy of detection, and making deformation detection more feasible and practical.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0052] Example: Please refer to Figures 1 to 3 、 Figures 5 to 7 As shown:

[0053] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a temperature-controlled ball valve that adapts to temperature difference changes, including: a valve seat 1, a snap-fit ​​valve part 2, a cooperative part 3, and a valve stem 4; the valve seat 1 and the snap-fit ​​valve part 2 are fixedly connected by bolts, the valve seat 1 and the snap-fit ​​valve part 2 are snapped together to form a flow pipe 101, the cooperative part 3 is arranged above the snap-fit ​​valve part 2, and the valve stem 4 is vertically arranged in the valve seat 1 and the snap-fit ​​valve part 2; it also includes: a deformation detection component 7 and a valve maintenance component 8, the deformation detection component 7 and the valve maintenance component 8 are on the same vertical line; the bottom end of the valve stem 4 is fixedly connected to a connecting column 5, the bottom end of the connecting column 5 is fixedly connected to a ball valve 6, and the deformation detection component 7 is used to detect the valve stem 4 Perform deformation detection; the deformation detection component 7 includes an electric control drive component 701 arranged on the cooperative component 3, a detection pipe 702 is opened in the valve stem 4, an electromagnet A703 is fixedly connected to the top of the inner cavity of the detection pipe 702, a sliding column 704 is slidably connected in the detection pipe 702, an electromagnet B705 is fixedly connected in the sliding column 704, an electric contact A706 is fixedly connected to the bottom end of the sliding column 704, an electric contact B707 is fixedly connected to the bottom of the inner cavity wall of the detection pipe 702, a spring 708 is fixedly connected to the bottom of the inner cavity wall of the detection pipe 702, a ring 709 is fixedly connected to the bottom of the spring 708, and an air release channel 710 is commonly opened on the valve stem 4 and the connecting column 5.

[0054] in:

[0055] The deformation detection component 7 is used to perform deformation detection on the valve stem 4 .

[0056] The electric control driving component 701 is mainly used to control the valve stem 4 to rotate according to the instructions of the control system.

[0057] A cylindrical through hole is passed through the middle of the electromagnet A703, which is mainly used to provide a channel for the gas of the external air pump to flow through; the sliding column 704 is slidably adapted to the detection pipe 702.

[0058] There is an electrical connection between the electrical contact A706 and the electrical contact B707. When the electrical contact A706 can move from top to bottom in the detection pipe 702 and come into contact with the electrical contact B707, it means that the valve stem 4 is in a normal state and has not been deformed.

[0059] The sliding cylinder 704 can be used in conjunction with the ring 709. When the sliding cylinder 704 moves to the position of the ring 709 and contacts the ring 709, the sliding cylinder 704 will overlap with the ring 709. At this time, the electrical contact A706 at the bottom end of the sliding cylinder 704 can contact the electrical contact B707.

[0060] It should be noted that: the sliding column 704 and the sliding cavity in which it is located, that is, the detection pipe 702, under normal circumstances, the axis line of the sliding column 704 and the axis line of the detection pipe 702 will be on the same axis line. When the valve stem 4 is deformed, the axis line of the sliding column 704 and the axis line of the detection pipe 702 are no longer on the same axis line. Even if slight deformation occurs, the sliding column 704 still cannot slide in the detection pipe 702.

[0061] Further examples: Please refer to Figures 2 to 5 、 Figure 8 As shown:

[0062] The valve maintenance assembly 8 is used to handle oil, dust, metal chips and impurities between the ball valve 6 and the circulation pipe 101. The valve maintenance assembly 8 includes a support plate 801 fixedly connected to the inner cavity of the valve seat 1, and a return spring body 802 is fixedly connected to the upper surface of the support plate 801. The upper end of the return spring body 802 is fixedly connected to an extrusion piece 803. A cleaning liquid capsule 804 is fixedly connected to the middle of the upper surface of the support plate 801, and a one-way circulation pipe 805 is fixedly connected to the bottom end of the cleaning liquid capsule 804. The one-way circulation pipe 805 is arranged through the support plate 801, and arc-shaped channels 806 are equidistantly opened on the connecting column 5, and recessed auxiliary grooves 807 are equidistantly opened on the ball valve 6.

[0063] in:

[0064] The valve maintenance assembly 8 is used to handle oil, dust, metal chips and other impurities between the ball valve 6 and the flow pipe 101.

[0065] Cleaning liquid capsule 804 contains a water-based cleaning solution. This solution is water-based and contains various surfactants, corrosion inhibitors, and chelating agents. It has excellent cleaning capabilities, removing impurities such as oil, dust, and metal shavings. It is also less corrosive to valve materials, making it suitable for cleaning temperature-controlled ball valves 6 made of various materials.

[0066] The one-way flow tube 805 is used to transfer the water-based cleaning liquid in the cleaning liquid bag 804 to the arc-shaped channel 806 .

[0067] The recessed auxiliary groove 807 is mainly used to cooperate with the arc-shaped channel 806 to disperse the water-based cleaning agent to the ball valve 6 and the inner wall of the nearby flow pipe 101.

[0068] The principle of temperature control is this: a temperature sensor senses the temperature of the environment or medium, converts the temperature signal into an electrical signal, and transmits it to the control system. The control system compares the received temperature signal with a preset temperature value. If the actual temperature is higher than the preset value, the control system issues a command to drive the electric actuator to rotate valve stem 4, causing ball valve 6 to rotate, reducing the valve opening, thereby reducing fluid flow and lowering the temperature. If the actual temperature is lower than the preset value, the control system issues the opposite command, increasing the valve opening, allowing more fluid to pass through and raising the temperature. This cycle continues to maintain the temperature within the set range.

[0069] Everything in the above example works as follows:

[0070] It should be noted that the operations of the deformability detection component 7 and the valve component maintenance component 8 are both performed when the valve stops working.

[0071] In the initial state:

[0072] The electromagnet B705 in the sliding cylinder 704 is magnetically attracted by the electromagnet A703 fixedly connected to the top of the inner cavity of the detection pipe 702, the electrical contact A706 is not in contact with the electrical contact B707, the spring 708 is not compressed, the return spring body 802 is not compressed, and the extrusion piece 803 is not in contact with the cleaning liquid bag 804.

[0073] The following is the working process of the deformability detection component 7:

[0074] It should be noted that: when testing the valve stem 4, the valve stem 4 can be divided into three situations: no deformation; deformation; because the valve stem 4 is located in the vertical auxiliary groove opened on the valve seat 1 and the snap-fit ​​valve member 2, due to the limitation of the auxiliary groove, under the action of water flow impact and rotating valve stem 4, slight cracks will occur due to torsional force, but due to the limitation of the auxiliary groove, it will not break in the short term and can still be used normally.

[0075] The following will explain the detection of the above three situations one by one.

[0076] First: No deformation and no cracks: Slowly supply air, and the electrical contacts A706 and B707 can contact each other, which indicates that the valve stem 4 is in a normal state.

[0077] During operation, the air pump is used to slowly pump air into the detection pipe 702 opened in the valve stem 4. Under this operation, the sliding cylinder 704, which was originally magnetically attracted to the electromagnet A703 by the electromagnet B705, will move from the top to the tail end in the detection pipe 702. During the movement, the sliding cylinder 704 will gradually move the electrical contact A706 at the bottom end closer to the electrical contact B707. Furthermore, since the valve stem 4 has not been deformed, the detection pipe 702 is in a straight line. As the sliding cylinder 704 continues to move, the sliding cylinder 704 will move to the detection pipe 702. The bottom end comes into contact with the ring 709. Furthermore, when the sliding cylinder 704 is blocked by the ring 709, since there is no crack in the valve stem 4, the gas pumped into the detection pipe 702 will not leak but will continue to increase. At this time, the sliding cylinder 704 will push the ring 709 to continue moving. At this time, the spring 708 is compressed, and finally the electrical contact A706 will come into contact with the electrical contact B707 at the bottom end of the detection pipe 702. At this time, the external display device that is electrically connected to the electrical contacts A706 and B707 will show that the valve stem 4 is in a normal, undeformed state.

[0078] Second: Deformation: Slowly supply air, and the electrical contacts A706 and B707 cannot contact each other, which means that the valve stem 4 is in an abnormal deformation state.

[0079] During operation, the air pump is used to slowly pump air into the detection pipe 702 opened in the valve stem 4. Under this operation, the sliding cylinder 704, which was originally magnetically attracted to the electromagnet A703 by the electromagnet B705, will move from the top to the tail end in the detection pipe 702. During the movement, the sliding cylinder 704 will gradually move the electrical contact A706 at the bottom closer to the electrical contact B707. However, due to the deformation of the valve stem 4, the sliding cylinder 704 cannot continue to move forward with the electrical contact A706, and eventually comes into contact with the electrical contact B707. At this time, the inspector can only reversely pump air through the air pump to suck the sliding cylinder 704 back to its initial state.

[0080] Third: No deformation occurs, but a gap appears due to external force: slowly supply air, because there is a crack and air will leak, so the electrical contacts A706 and B707 cannot make contact; perform a second inspection, supply air quickly, the electrical contacts A706 and B707 can make contact, then it is confirmed that at this time the valve stem 4 has a slight crack, but no deformation.

[0081] During operation, the air pump is used to slowly pump air into the detection pipe 702 opened in the valve stem 4. Under this operation, the sliding cylinder 704, which was originally magnetically attracted to the electromagnet A703 by the electromagnet B705, will move from the top to the tail end in the detection pipe 702. During the movement, the sliding cylinder 704 will gradually bring the electrical contact A706 at the bottom end closer to the electrical contact B707. Furthermore, since the valve stem 4 has not been deformed, the detection pipe 702 is in a straight line. As the sliding cylinder 704 continues to move, the sliding cylinder 704 will move to the bottom end of the detection pipe 702 and contact the ring 709. Furthermore, when the sliding cylinder 704 is blocked by the ring 709, the valve stem 4 will crack at this time. Therefore, the gas pumped into the detection pipe 702 will leak from the gap, that is, the electrical contact A706 will not contact the electrical contact B707 at the bottom end of the detection pipe 702 at this time.

[0082] Furthermore, the design of the deformation detection component 7 can bring the benefits of ensuring the safe and stable operation of the system and early warning of faults for the valve body with deformation detection of the valve stem 4. It can monitor the deformation of the valve stem 4 in real time and issue a warning in time when the valve stem 4 begins to deform slightly, so that the staff can take measures in advance to avoid further aggravation of the deformation of the valve stem 4, which may lead to serious problems such as the inability of the ball valve 6 to open and close normally and fluid leakage, thereby ensuring the safe and stable operation of the entire pipeline system.

[0083] Prevent chain reactions: In complex industrial piping systems, a valve failure can trigger a series of chain reactions. By detecting the deformation of the valve stem 4, problems can be discovered and addressed in a timely manner, preventing valve failures caused by valve stem 4 deformation from spreading to other equipment and pipelines, avoiding larger-scale production accidents and economic losses.

[0084] Improve production efficiency and reduce downtime: Traditional manual inspections are difficult to detect early deformation of the valve stem 4, and repairs are often delayed until the problem becomes serious, resulting in long downtime. This design's deformation detection allows maintenance personnel to perform repairs or replacements at the appropriate time, allowing for planned maintenance work. This significantly reduces unexpected downtime caused by sudden valve stem 4 failures, improves production equipment utilization, and ensures production continuity.

[0085] Extending equipment life: By promptly discovering and addressing the deformation problem of the valve stem 4, additional wear and damage to other valve components and the pipeline system caused by excessive deformation of the valve stem 4 is avoided, thereby extending the service life of the valve and the entire pipeline system, reducing the frequency of equipment updates and replacements, and saving equipment investment costs.

[0086] Furthermore, by using gas as the driving force for the sliding cylinder 704, high-sensitivity detection is achieved even when the valve stem 4 is cracked but not deformed due to torsional force caused by water flow impact. The large spacing between gas molecules and their high fluidity allow for rapid response to even small changes. When tiny cracks are present in the valve stem 4 due to torsional force, even the smallest cracks can be rapidly leaked through by gas, allowing inspectors to promptly detect abnormalities through indirect feedback from electrical contacts A 706 and B 707. Compared to other detection methods, this method is more sensitive to detecting these initial tiny cracks, significantly improving detection accuracy.

[0087] Non-destructive testing characteristics: The gas is mild in nature and will not cause additional wear or damage to the valve stem 4 like some physical testing methods, such as mechanical contact testing, nor will it cause chemical reactions like chemical testing methods. This ensures that the original performance and structural integrity of the valve stem 4 will not be affected during the testing process, maintaining the normal working state of the valve stem 4;

[0088] Multi-dimensional detection supplement: Gas detection can detect cracks in the valve stem 4 but no deformation, which complements the traditional detection method that focuses on the deformation of the valve stem 4. It evaluates the health status of the valve stem 4 from different angles, provides richer information for a comprehensive understanding of the status of the valve stem 4, improves the entire detection system, and makes the detection results more valuable for reference.

[0089] Please refer to the above working process Figures 1 to 3 、 Figures 5 to 7 .

[0090] The following is the working process of the valve maintenance component 8:

[0091] When using,

[0092] Furthermore, the valve maintenance assembly 8 improves overall maintenance convenience and efficiency, eliminating the need to disassemble the valve body. Conventional valve cleaning and maintenance often requires disassembling the valve seat 1 and the valve member 2, which is time-consuming and labor-intensive, and can also damage the valve body due to improper handling during disassembly. The valve maintenance assembly 8, however, allows for cleaning without disassembling the valve body, significantly saving maintenance time and costs and improving efficiency.

[0093] Fast cleaning: It can quickly and effectively deliver water-based cleaning liquid to the wall of the valve body circulation pipe 101 and the surface of the ball valve 6, quickly dealing with oil, dust and metal chips impurities, reducing the accumulation of impurities inside the valve body, shortening the time of a single maintenance, and allowing the valve body to be restored to a good working condition more quickly;

[0094] Extend the service life of the valve body and reduce friction loss: By using a water-based cleaning fluid to clean and lubricate the wall of the valve body circulation pipe 101 and the surface of the ball valve 6, the friction coefficient between the ball valve 6 and the wall of the circulation pipe 101 when it rotates can be effectively reduced, friction loss can be reduced, and problems such as component wear and deformation caused by long-term friction can be avoided, thereby extending the service life of the valve body; prevent corrosion by impurities, and promptly remove oil, dust and metal chips inside the valve body to avoid chemical reactions between these impurities and the valve body material, prevent corrosion, and protect the structural integrity and performance stability of the valve body.

[0095] Furthermore, by designing the valve stem 4 into a hollow structure, the heat dissipation performance of the overall operation can be improved: in some environments with high operating temperatures, the internal space of the hollow valve stem 4 is conducive to air circulation, thereby enhancing the heat dissipation capacity of the valve stem 4, helping to reduce the operating temperature of the valve stem 4, preventing the degradation of material properties and aging of seals caused by overheating, and improving the reliability and stability of the valve;

[0096] Optimized spatial layout: The hollow valve stem 4 provides a detection space for deformation detection, making the detection method flexible and diverse, optimizing the detection system layout, so that the detection components are no longer randomly distributed outside the valve body, reducing the hidden dangers of failure caused by aging and wear of the lines, and facilitating maintenance and management; in addition, it reduces the detection cost, eliminates the need to design a complex external structure for detection, saves additional detection equipment and installation costs, improves the economy of detection, and makes deformation detection more feasible and practical.
