Description

Technical Field

[0001] This invention relates to the field of power equipment maintenance technology, and in particular to a method, equipment, medium, and product for determining the optimization scheme of a main combination valve. Background Technology

[0002] The main combination valve is an integrated valve in a steam turbine or gas turbine system, serving as a control and protection device on the main steam passage of the thermal system. The guide sleeve and bushing in the main combination valve are key sliding fit components ensuring the accuracy of valve stem movement and the reliability of the seal. In long-term high-temperature operating environments, the guide sleeve in the main combination valve may partially detach from the valve stem bushing and fail to return to its original position. This means that the main combination valve often experiences jamming, incomplete closure, and other abnormalities in long-term high-temperature operation, affecting the performance of supercritical and ultra-supercritical generator units and even posing serious safety hazards.

[0003] For main control valves exhibiting abnormalities such as jamming or incomplete closure, the common approach is to request the equipment manufacturer to re-manufacture a new main control valve component according to its original structural dimensions. This new component then replaces the faulty valve structure for electrical operation. However, simply customizing the main control valve component does not improve its performance. Contacting the equipment manufacturer, their manufacturing process, and the transportation and installation of the new valve all require time. Component replacement is costly, and delayed replacement can disrupt the power system's operation. Summary of the Invention

[0018] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the method for determining the optimization scheme of the main combined valve in any embodiment of the present invention.

[0019] According to another aspect of the present invention, a computer program product is provided, the computer program product including a computer program, which, when executed by a processor, implements the method for determining the optimization scheme of the main combined valve according to any embodiment of the present invention.

[0020] The method for determining the optimization scheme of the main combined valve of the present invention includes: obtaining the device parameters of the target main combined valve, and constructing a three-dimensional model sample of the target main combined valve according to a pre-set component design scheme and the device parameters of the target main combined valve; obtaining the test requirements of the target main combined valve, and performing simulation tests on the three-dimensional model sample using the test requirements of the target main combined valve to obtain the simulation pull-out force test results of the target main combined valve; determining a backup three-dimensional model sample from the three-dimensional model sample based on the simulation pull-out force test results, and constructing a test sample of the target main combined valve based on the sample parameters of the backup three-dimensional model sample; performing performance tests on the test sample using the test requirements of the target main combined valve to obtain the test pull-out force test results of the target main combined valve, and determining the optimization scheme of the target main combined valve based on the test pull-out force test results.

It eliminates the need to request the equipment manufacturer to re-process a new main combined valve according to the original structural dimensions of the abnormal main combined valve, reducing the impact of the main combined valve replacement task on the power system operation and improving the stability of the power system.

[0032] Figure 1This is a flowchart illustrating a method for determining an optimization scheme for a main combination valve provided by the present invention. This embodiment is applicable to determining the optimization scheme of a target main combination valve with high efficiency and low cost, improving the replacement efficiency of the main combination valve, and reducing the impact of the main combination valve replacement task on the operation of the power system. This method can be executed by the device for determining the optimization scheme of the main combination valve provided by the present invention. This device can be implemented in hardware and / or software. In a specific embodiment, this device can be integrated into an electronic device. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. Figure 1 The method specifically includes the following steps:

[0033] S101. Obtain the device parameters of the target main combined valve, and construct a three-dimensional model of the target main combined valve according to the pre-set component design scheme and the device parameters of the target main combined valve.

[0034] The target main combination valve can be understood as a main combination valve that requires backup in case of failure. For example, it could be a main combination valve with a long operating time (the difference between its operating time and the safe operating time of the component is less than 6 months, 1 year, or 2 years). This is to pre-determine and customize replaceable prototypes of the target main combination valve so that a backup prototype can be promptly replaced in case of an anomaly, maintaining the operation of the power system. The power system includes various types of main combination valves (different sizes, structural forms, manufacturers, and performance parameters). Different types of main combination valves possess different characteristic information. The device parameters of the target main combination valve can be understood as its characteristic information, including but not limited to size, structural form, manufacturer, and performance parameters, used to distinguish different types of main combination valves. Since the main combination valve is a large-scale device, the implementation difficulty and cost of prototype construction and performance testing are high. Therefore, this invention will transform the structure of the main combination valve according to certain rules, scaling it proportionally to facilitate prototype construction and performance testing. This also improves the efficiency of prototype construction and performance testing, saving costs. The pre-defined component design scheme can be understood as the structural transformation rules for the main combination valve, including the structural transformation method, dimensional scaling, material selection method, and tolerance adjustment method. The 3D model prototype of the target main combination valve can be understood as a 3D test model of the target main combination valve. The 3D test model can be used for simulation testing, and the simulation test results can present the performance of the main combination valve corresponding to the 3D test model, so as to select replacement prototypes for the target main combination valve.

[0035] Figure 2 This is a schematic diagram of the structure of a main combination valve provided by the present invention. Figure 2 As can be seen, the main combination valve includes a bushing and a guide sleeve, with the guide sleeve nested inside the bushing. Figure 2In the closed state of the guide sleeve and bushing, when the main combined valve is operating under high temperature and pressure, the valve stem applies a force to the guide sleeve during opening and closing. Combined with the deterioration of the bushing and guide sleeve materials, over time, the guide sleeve and bushing may detach or fail to close properly. A main combined valve with closure problems will cease operation, requiring component replacement, primarily of the guide sleeve, to ensure the main combined valve can continue operating the power system. This invention aims to determine a stable combination of bushing and guide sleeve, specifically a combination capable of withstanding high pull-out forces. Figure 3 This is a schematic diagram of a main combination valve prototype provided by the present invention. Proportional conversion of the same structure would result in an infinitely small guide sleeve size, which is not conducive to testing the pull-out force. The present invention constructs the actual main combination valve as follows: Figure 3 The structure shown was subjected to a pull-out force test. The structural conversion method can be understood as... Figure 2 The main combined valve structure shown is converted to Figure 3 The scalability of the main combined valve structure shown can be understood as a scaling factor (0.2x, 0.4x, etc.) of the main combined valve. The materials for the bushing and guide sleeve are subject to selection; materials suitable for power systems are generally high-alloy steel and cobalt-based superalloys. Due to the relatively large size of the bushing, the guide sleeve is replaced first when replacing components. Only when replacing the guide sleeve cannot meet the power system requirements will the bushing be replaced, or both the guide sleeve and bushing, be considered for replacement. Therefore, the material selection method of this invention is to determine the bushing material according to the material of the target main combined valve, and to determine the guide sleeve material as high-alloy steel or cobalt-based superalloy. From Figure 3 It can be seen that the guide sleeve and the bushing are nested together. The outer diameter of the guide sleeve tube nested inside the bushing is the maximum diameter of the guide sleeve. The outer circle of the guide sleeve near the end face of the bushing and the inner circle of the bushing are in clearance fit at room temperature. The tolerance adjustment method can be understood as the adjustment method of the outer circle diameter of the guide sleeve near the end face of the bushing, including the adjustment scale and adjustment range. Adjusting the outer circle diameter of the guide sleeve near the end face of the bushing is to increase the contact area between the guide sleeve and the bushing under high temperature conditions and increase the friction between the guide sleeve and the bushing. On the other hand, it is to make the guide sleeve and the bushing have interference nesting characteristics under the premise of reasonable installation, improve the stability of the main combined valve sample, and make the main combined valve sample have a higher pull-out force. This invention does not limit this.

[0036] It is worth noting that the method of the present invention is also applicable to main combination valves that have already malfunctioned. In this case, the target main combination valve is a malfunctioning main combination valve that has been inspected by maintenance personnel (mainly a main combination valve where the guide sleeve and bushing are not tightly closed).

[0037] In one specific implementation, a three-dimensional model prototype of the target main combined valve is constructed according to a pre-set component design scheme and the device parameters of the target main combined valve. This includes: determining the three-dimensional model structure of the target main combined valve based on the structural conversion method, size scaling scale, and device parameters of the target main combined valve. The three-dimensional model structure includes a guide sleeve and a bushing. The bushing material and guide sleeve material are determined according to the material selection method, and the guide sleeve interface diameter is determined according to the tolerance adjustment method. The three-dimensional model prototype is determined based on the combination of the three-dimensional model structure, bushing material, guide sleeve material, and guide sleeve interface diameter.

[0038] The three-dimensional model structure of the target main combined valve can be understood as a main combined valve prototype with defined dimensions, that is, a prototype with specific dimensions. Figure 3 The sample shown can be understood as follows: the guide sleeve interface diameter can be understood as the outer diameter of the guide sleeve near the bushing end face; the 3D model sample can be understood as a collection of samples with different combinations. The 3D model sample includes at least one sub-model sample, and the number of sub-model samples is the same as the number of combinations of the 3D model structure, bushing material, guide sleeve material, and guide sleeve interface diameter.

[0039] Specifically, assuming the bushing material is high-alloy steel, the guide sleeve material is high-alloy steel or cobalt-based superalloy, and the guide sleeve interface diameters are P1, R1, P2, and R2, then the three-dimensional model samples include sub-model sample 1 (guide sleeve material is cobalt-based superalloy, guide sleeve interface diameter is P1), sub-model sample 2 (guide sleeve material is cobalt-based superalloy, guide sleeve interface diameter is P2), sub-model sample 3 (guide sleeve material is cobalt-based superalloy, guide sleeve interface diameter is R1), sub-model sample 4 (guide sleeve material is cobalt-based superalloy, guide sleeve interface diameter is R2), sub-model sample 5 (guide sleeve material is high-alloy steel, guide sleeve interface diameter is P1), sub-model sample 6 (guide sleeve material is high-alloy steel, guide sleeve interface diameter is P2), sub-model sample 7 (guide sleeve material is high-alloy steel, guide sleeve interface diameter is R1), and sub-model sample 8 (guide sleeve material is high-alloy steel, guide sleeve interface diameter is R2).

[0040] The advantage of this setup is that it constructs model prototypes under all matching combinations, ensuring the comprehensiveness of the simulation results. This allows for the selection of combinations with superior performance for actual testing, thereby maximizing the performance of the main combined valve prototype.

[0041] S102. Obtain the test requirements of the target main combined valve, and use the test requirements of the target main combined valve to perform simulation tests on the three-dimensional model sample to obtain the simulation pull-out force test results of the target main combined valve.

[0042] To reduce the cost of prototype construction and testing, this invention first constructs model prototypes and simulates them. Based on the simulation results, it selects model prototypes with better pull-out resistance from the constructed model prototypes. Only the selected model prototypes with better pull-out resistance are used for actual prototype construction and testing, which can effectively save prototype testing resources and costs. The testing requirements of the target main control valve can be understood as the performance test points of the target main control valve. The test results of the target main control valve under the performance test points corresponding to the simulation task can represent the normal state performance of the target main control valve, which is used to screen out model prototypes with poor pull-out force, such as screening out prototypes with the bottom two pull-out forces, and screening out prototypes with pull-out forces lower than the application requirements of the main control valve. The testing requirements for the target main control valve include temperature testing requirements and model time testing requirements. The temperature testing requirement is the maximum operating temperature of the main control valve, which is generally 630 degrees Celsius. The model time testing requirement can be understood as the duration of high-temperature treatment of the model sample. The model time testing requirement is generally 500 hours, that is, the model sample is subjected to 500 hours of high-temperature treatment at 630 degrees Celsius before the pull-out force is tested. In special cases, it can also be 0 hours or 1000 hours.

[0043] The simulation test of the three-dimensional model sample using the test requirements of the target main combined valve can be understood as testing the pull-out force of the three-dimensional model sample after being treated at a high temperature of 630 degrees for 500 hours. The maximum pull-out force can be understood as the magnitude of the force that separates the bushing and the guide sleeve. The simulation pull-out force test result can be understood as the maximum pull-out force of the three-dimensional model sample after being treated at a high temperature of 630 degrees for 500 hours.

[0044] In one specific implementation, the three-dimensional model sample is simulated and tested according to the testing requirements of the target main combined valve to obtain the simulated pull-out force test results of the target main combined valve. This includes: determining the simulation test conditions of the target main combined valve based on the temperature test requirements and the model time test requirements (i.e., treating the sample at 630 degrees for 500 hours); under the simulation test conditions, testing the simulated high-temperature pull-out force of the three-dimensional model sample (i.e., placing the three-dimensional model sample treated at 630 degrees for 500 hours in a 630-degree high-temperature test environment for testing, and obtaining the pull-out force that can separate the bushing and the guide sleeve), and obtaining the simulated pull-out force test results (the maximum pull-out force of the three-dimensional model sample after high-temperature aging treatment at 630 degrees).

[0045] The simulation test of this invention has a corresponding simulation scheme. The parameters of the simulation scheme are adjusted and optimized in advance based on the simulation results and experimental results of the training sample. When the matching degree between the experimental results of the training sample and the simulation results obtained based on the simulation scheme is greater than 90%, the simulation scheme is determined to be applicable to the simulation pull-out force test task of the main combined valve. When the matching degree between the experimental results of the training sample and the simulation results obtained based on the simulation scheme is not greater than 90%, the simulation parameters of the simulation scheme need to be adjusted and the test needs to be repeated until the matching degree between the simulation results of the training sample and the experimental results is greater than 90%. Only then can the simulation scheme execute the simulation pull-out force test task of the main combined valve. It is worth noting that when training and optimizing the simulation parameters of the simulation scheme, only data within 1000 hours are tested. This setting is to reduce the impact of high-temperature deformation of the material on the accuracy of the simulation scheme. On the one hand, the present invention can use the simulation results and experimental results of samples that have undergone 0 hours or 500 hours of high-temperature aging treatment to train and optimize the simulation parameters of the simulation scheme, so as to improve the training efficiency and optimization efficiency of the simulation scheme. On the other hand, in order to ensure the accuracy and comprehensiveness of the simulation scheme, the present invention can also use the simulation results and experimental results of samples that have undergone 0 hours and 500 hours of high-temperature aging treatment to train and optimize the simulation parameters of the simulation scheme, and the present invention does not limit this.

[0046] S103. Based on the simulation pull-out force test results, determine the backup three-dimensional model sample from the three-dimensional model sample, and construct the test sample of the target main combined valve based on the sample parameters of the backup three-dimensional model sample.

[0047] The backup 3D model prototype can be understood as a relatively stable prototype selected from the 3D model prototypes (a prototype with a large pull-out force, for example, a prototype with a pull-out force ranking in the top X, where the pull-out force exceeds the application requirements of the main control valve, and X is related to the prototype construction and testing requirements). The prototype parameters of the backup 3D model prototype can be understood as the prototype dimensions, structure, material, and tolerances, etc., used to assist in constructing the test prototype of the target main control valve. The test prototype can be understood as a backup 3D model prototype that has been physically manufactured. The purpose of this setup is to determine the optimal backup main control valve for the target main control valve through simulation tests + physical tests. Generally, it is a prototype that can withstand a large pull-out force for a long time, which can greatly extend the service life of the replaced main control valve.

[0048] In one specific implementation, the process of determining backup 3D model samples from the 3D model samples based on the simulated pull-out force test results includes: identifying sub-model samples whose simulated high-temperature pull-out force is greater than a preset simulated high-temperature pull-out force threshold (the corresponding value of the maximum force value of the main combined valve during operation in the simulation environment; a value greater than this indicates that the sample can adapt to the operation of the main combined valve in the actual operating environment) as the first candidate 3D model samples, that is, selecting samples that can meet the force requirements of the main combined valve at any time; and performing simulation testing in descending order of pull-out force. The simulated high-temperature pull-out forces of the 3D model samples under simulated test conditions are ranked, and the sub-model samples whose simulated high-temperature pull-out force ranking results meet the preset simulation high-temperature pull-out force ranking conditions (ranked in the top 3, top 5, etc.) are determined as the second candidate 3D model samples. That is, samples with better stress performance or more stable performance in the simulation results are selected. The first and second candidate 3D model samples are then processed (i.e., sample deduplication is performed to avoid repeated processing of the same type of model sample, which wastes processing and testing resources) to obtain spare 3D model samples. The advantage of this setup is that samples with better stress performance or more stable stress performance in the simulation results can be selected and processed into test samples, reducing the number of samples in actual tests, saving test resources, improving test efficiency, and eliminating the need for meaningless sample tests.

[0049] S104. The performance of the test specimen is tested according to the test requirements of the target main combined valve. The test pull-out force test results of the target main combined valve are obtained, and the optimization scheme of the target main combined valve is determined based on the test pull-out force test results.

[0050] Specifically, conducting performance tests on the test specimens based on the testing requirements of the target main control valve can be understood as placing the test specimens under the test conditions indicated by the testing requirements of the target main control valve. The test pull-out force test results of the target main control valve can be understood as the maximum pull-out force data under each test condition. The optimization scheme for the target main control valve can be understood as the component replacement method of the target main control valve, that is, what material and tolerance guide sleeve to replace with the target main control valve.

[0051] Main control valves typically operate for extended periods in high-temperature environments; therefore, the stress on these valves during different high-temperature operations is of great concern. The testing requirements for the target main control valve include time-based testing and at least four high-temperature aging treatments. The high-temperature aging treatment requirements specify the duration of the test specimen's treatment in a high-temperature environment, with minimum requirements of 500 hours, 1500 hours, 2500 hours, and 3000 hours. Specifically, the test specimen is subjected to aging treatments at 630℃ for at least 500 hours, 1500 hours, 2500 hours, and 3000 hours, followed by a high-temperature (630℃) pull-out force test. Generally, to ensure sufficient and comprehensive test data, six aging treatment periods are performed: 500 hours, 1000 hours, 1500 hours, 2000 hours, 2500 hours, and 3000 hours.

[0052] Optionally, the performance of the test specimen is tested according to the test requirements of the target main combined valve to obtain the test pull-out force test results of the target main combined valve. This includes: determining at least four test conditions (i.e., at least four different high-temperature aging treatments) of the target main combined valve based on the temperature test requirements and at least four high-temperature aging treatment requirements, with each test condition and high-temperature aging treatment requirement corresponding one-to-one; testing the test high-temperature pull-out force of the test specimen under each of the at least four test conditions to obtain the test pull-out force test results, with at least two test specimens under each test condition.

[0053] The test conditions can be understood as a matched combination of temperature testing requirements and high-temperature aging treatment requirements, equivalent to the high-temperature aging treatment conditions of the test specimens, such as 500 hours at 630 degrees Celsius, 1000 hours at 630 degrees Celsius, 1500 hours at 630 degrees Celsius, 2000 hours at 630 degrees Celsius, 2500 hours at 630 degrees Celsius, and 3000 hours at 630 degrees Celsius. The test pull-out force results are the maximum pull-out force of the test specimen treated at 630 degrees Celsius for 500 hours, the maximum pull-out force of the test specimen treated at 630 degrees Celsius for 1000 hours, ..., the maximum pull-out force of the test specimen treated at 630 degrees Celsius for 3000 hours. Specifically, the performance testing of the test specimens based on the testing requirements of the target main control valve can be understood as testing the pull-out force of the test specimens after aging treatment at 630 degrees Celsius for 500 hours, 1000 hours, 1500 hours, 2000 hours, 2500 hours, and 3000 hours. The test pull-out force result is the maximum pull-out force (i.e., the magnitude of the force separating the bushing and guide sleeve) of the test specimens after aging treatment at 630 degrees Celsius for 500 hours, 1000 hours, 1500 hours, 2000 hours, 2500 hours, and 3000 hours.

[0054] It is worth noting that, to ensure the reliability of the test results, the same sample is placed under each test condition, and sub-test samples are placed under each test condition. Furthermore, two or three sub-test samples are placed under each test condition. The maximum pull-out force of this type of sub-test sample is the average of the maximum pull-out forces of sub-test samples of the same type. This avoids the impact of individual sample differences on the test results, preventing a certain type of sample from being disqualified as an alternative. The advantage of this setup is that it yields comprehensive test results, aiding in the optimization of the main control valve's performance.

[0055] In one specific implementation, the optimization scheme for the target main combined valve is determined based on the test pull-out force results. This includes: identifying sub-test samples whose high-temperature pull-out forces under each test condition are greater than a preset high-temperature pull-out force threshold (the maximum force value of the main combined valve during operation corresponding to the test conditions; a value greater than this indicates that the sample can adapt to the operation of the main combined valve in the actual operating environment) as the optimization scheme for the target main combined valve; and / or, ranking the high-temperature pull-out forces of the test samples under each test condition in descending order of pull-out force, and identifying sub-test samples whose high-temperature pull-out force ranking results under each test condition meet the preset high-temperature pull-out force ranking conditions (top 3, top 5, etc.) as the optimization scheme for the target main combined valve. The advantage of this setup is that it allows for the selection of samples (one or more) that exhibit good stress performance or stable stress characteristics from the test results, using them as the optimization scheme for the target main combined valve, and providing diverse component maintenance methods for maintenance personnel to choose from.

[0056] Figure 4 This is a schematic diagram of the high-temperature pull-out force test results provided by the present invention, showing four different types of samples. Figure 4 As can be seen, the high-temperature pull-out force is different for different parts. The test results can help in the selection of samples. Figure 4 For simulation results, sample 1 and sample 2 can be selected as backup 3D model samples. Test samples are fabricated and performance tests are conducted. Figure 4 Based on the test results, relevant parameters of sample 1 can be selected as the optimization scheme for the target main combined valve. For example, the guide sleeve material and tolerance data corresponding to sample 1 can be selected as the spare guide sleeve parameters for the target main combined valve, so as to process the spare guide sleeve of the target main combined valve and replace the parts when the target main combined valve malfunctions.

[0057] After determining the optimization scheme of the target main combined valve, the optimization scheme determination method of the present invention further includes: determining the associated main combined valve in the power system with the same device parameters as the target main combined valve, that is, the main combined valve of the same model as the target main combined valve, and determining the optimization scheme of the associated main combined valve based on the optimization scheme of the target main combined valve, that is, sharing the optimization scheme of the target main combined valve with the associated main combined valve so as to replace it in time when the associated main combined valve is abnormal, thereby improving the maintenance efficiency of the associated main combined valve and reducing the maintenance cost of the associated main combined valve.

[0058] Normally, the quality inspection interval for the main combined valve is once a year. When the target main combined valve is an abnormal main combined valve, the optimization scheme determination method of this invention further includes: adjusting the quality inspection interval of the associated main combined valve based on the running time of the target main combined valve and the running time of the associated main combined valve. That is, determining the time difference between the running time of the associated main combined valve and the running time of the target main combined valve. The smaller the time difference, the closer the associated main combined valve is to its stable operating period. The time interval between the associated main combined valves can be appropriately shortened. For example, the running time of the associated main combined valve and the running time of the target main combined valve... When the time difference is greater than 2 years, the quality inspection interval is determined to be 2 years. When the time difference between the running time of the associated main combined valve and the running time of the target main combined valve is less than 2 years, the quality inspection interval is determined to be 1 year. When the time difference between the running time of the associated main combined valve and the running time of the target main combined valve is less than 1 year, the quality inspection interval is determined to be 6 months, etc. The purpose of this setting is to ensure timely detection of abnormalities in the main combined valve, reduce its impact on the power system, and ensure the safety and stability of the power system. The specific time interval is related to the maintenance rules and usage of the equipment, and this invention does not limit it.

[0059] Furthermore, when it is urgent to determine the replacement method for a component of a certain type of main combination valve (candidate main combination valve), power workers can issue a simulation optimization instruction for that type of main combination valve (equivalent to an instruction to determine the optimization suggestion for that type of main combination valve based solely on the simulation results). At that time, the simulation scheme of the target main combination valve will be directly used to simulate and test the three-dimensional model sample of that type of main combination valve, and the optimization scheme of that type of main combination valve will be determined based on the simulation test results. That is, the sample construction method (including material selection and tolerance selection) corresponding to the model sample with the largest pull-out force in the simulation results will be determined as the optimization scheme of that type of main combination valve.

[0060] The technical solution of the above embodiment constructs a three-dimensional model of the target main combined valve based on its device parameters and component design scheme. Simulation tests are then performed on the three-dimensional model according to the testing requirements of the target main combined valve. A subset of these models are selected as backup three-dimensional model models. Test models are constructed based on the parameters of the backup three-dimensional model models. Performance tests are then conducted on the test models using the testing requirements of the target main combined valve. Based on the two test results, the component replacement scheme that best suits the target main combined valve is selected from the test models. For example, the model with the longest safe operating time, or the model that meets the safe operating requirements and has a lower cost, etc. This method can efficiently and cost-effectively determine the optimal scheme for the target main combined valve, improving the replacement efficiency of the main combined valve. It eliminates the need to request the equipment manufacturer to re-process a new main combined valve according to the original structural dimensions of the abnormal main combined valve, reducing the impact of the main combined valve replacement task on the power system operation and improving the stability of the power system.
