Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of natural gas wellhead equipment, in particular to a cage sleeve design method and device for a cage sleeve type throttle valve under extra-high pressure working conditions. BACKGROUND

[0002] The importance of natural gas in the global energy structure is self-evident. In the process of extra-high pressure natural gas transmission, cage sleeve type throttle valves are widely used, and the cage sleeve assembly inside is the key to determining the performance and service life of the throttle valve. Since the extra-high pressure working condition puts forward higher requirements for the precise control and efficient throttling of the throttle valve, the traditional cage sleeve structure often cannot meet these needs, which limits the overall performance of the cage sleeve type throttle valve in the extra-high pressure environment. Therefore, it is urgent to design a new type of cage sleeve structure to improve the performance of the throttle valve under extra-high pressure working conditions.

[0003] At present, although the design of the cage sleeve type throttle valve usually adopts a mechanical design method, this method of directly changing the shape or size of the traditional cage sleeve does not fully consider the complex factors under extra-high pressure working conditions. The lack of a design process combining theoretical calculation and simulation analysis makes it difficult to accurately predict and evaluate the performance and adaptability of the new cage sleeve structure under extra-high pressure complex working conditions. This may result in the new type of cage sleeve not achieving the expected throttling effect in actual extra-high pressure applications, and even may exist potential safety risks. SUMMARY

[0004] In view of the above problems, the present application provides a cage sleeve design method and device for a cage sleeve type throttle valve under extra-high pressure working conditions, the main purpose is to optimize the cage sleeve structure in a targeted manner combined with safety hazards, to ensure that the optimized cage sleeve structure applied in the throttle valve can achieve the expected effect.

[0005] To solve the above technical problems, the present application proposes the following solutions:

[0010] The internal flow field simulation model, the acoustic-vibration coupling simulation model and the erosion simulation model of the optimal cage structure corresponding to the optimal actual flow relationship curve are determined by using a simulation simulation method.

[0011] The internal flow field simulation of the optimal cage structure is performed by using the internal flow field simulation model, and internal flow field simulation results are obtained, which are used to represent the velocity distribution and pressure distribution of the fluid inside the cage type throttle valve.

[0014] The target cage structure is obtained by optimizing the optimal cage structure according to the internal flow field simulation results, the acoustic-vibration coupling simulation results and the erosion simulation results, wherein the optimization of the optimal cage structure includes optimizing the material and structure of the cage, and the structure includes the shape, size and layout of the throttle hole.

[0015] In a second aspect, the present application provides a cage design device for a cage type throttle valve under extra-high voltage working conditions, the device comprising:

[0019] A model determination unit is configured to determine an internal flow field simulation model, an acoustic-vibration coupling simulation model and an erosion simulation model of an optimal cage structure corresponding to the optimal actual flow relationship curve screened by the curve screening unit by using a simulation simulation method.

[0020] The first simulation unit is used to perform internal flow field simulation on the optimal cage structure using the internal flow field simulation model, and obtain the internal flow field simulation results. The internal flow field simulation results are used to characterize the velocity distribution and pressure distribution of the fluid inside the cage-type throttle valve.

[0021] The second simulation unit is used to perform acoustic-vibration coupling simulation on the optimal cage structure using the acoustic-vibration coupling simulation model, and obtain acoustic-vibration coupling simulation results. The acoustic-vibration coupling simulation results are used to characterize the sound waves and vibrations generated by the optimal cage structure during operation.

[0022] The third simulation unit is used to perform erosion simulation on the optimal cage structure using the erosion simulation model to obtain erosion simulation results.

It can obtain the cage structure corresponding to multiple target throttling flow rates using natural gas throttling theory calculation formulas, thereby establishing a close mathematical relationship between the cage structure design and the required throttling flow rate. This not only improves the accuracy of the design but also enhances its feasibility. Next, multiple sets of actual flow relationship curves for the cage structures can be plotted. These curves visually demonstrate the flow rate variation under each cage structure, providing a visual basis for subsequent optimization. Based on this, further optimization processing can be performed on the multiple sets of actual flow relationship curves to select the optimal actual flow relationship curve, thus obtaining the optimal cage structure corresponding to the optimal actual flow relationship curve. Finally, simulation methods can be used to determine the internal flow field simulation model, acoustic-vibration coupling simulation model, and erosion simulation model of the optimal cage structure. Then, the internal flow field simulation model is used to simulate the internal flow field of the optimal cage structure, and the simulation results are used to characterize the velocity and pressure distribution of the fluid inside the cage-type throttle valve. At the same time, the acoustic-vibration coupling simulation model is used to simulate the acoustic-vibration coupling of the optimal cage structure, and the simulation results are used to characterize the sound waves and vibrations generated by the optimal cage structure during operation. Additionally, the erosion simulation model is used to simulate the erosion of the optimal cage structure, and the simulation results are used to characterize the erosion of the optimal cage structure under different sand mass flow rates, different sand particle sizes, different fluid velocities, and different throttling pressure differences. Finally, the optimal cage structure can be optimized based on the simulation results of internal flow field, acoustic-vibration coupling, and erosion, resulting in the target cage structure. Optimization of the optimal cage structure includes optimizing the material and structure of the cage, specifically the shape, size, and layout of the throttling orifice. Simulation allows for a detailed understanding of the simulated operation of this optimal cage structure during the design phase, leading to a comprehensive performance evaluation. This not only helps in the early detection of potential safety hazards but also enables targeted optimization of the cage structure based on these hazards, ensuring the effective application of the optimized target cage structure in ultra-high pressure throttling valves and improving the overall safety and operational efficiency of the ultra-high pressure natural gas transmission system.

[0034] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0035] To address the problem that current mechanical design methods for cage-type throttling valves may fail to achieve the desired performance or pose potential safety hazards in practical applications, the inventors have developed a cage-type throttling valve design method specifically for ultra-high pressure (UHV) conditions. This method combines theoretical calculations to establish a close mathematical relationship between the cage-type structure design and the required throttling flow rate, significantly improving the accuracy and feasibility of the design. Furthermore, this method utilizes model simulation technology to gain a detailed understanding of the simulated operation of the cage-type structure during the design phase, obtaining comprehensive performance evaluation results. This not only helps to identify potential safety hazards in advance but also allows for targeted optimization of the cage-type structure to address these hazards, ensuring that the optimized target cage-type structure achieves the expected performance in the throttling valve. Additionally, the UHV conditions in this invention specifically refer to pressures of 130 MPa and above.

[0036] Next, combined Figure 1This invention describes a cage sleeve design method for a cage-type throttle valve under ultra-high voltage conditions, as proposed in an embodiment of the invention. The specific execution steps are as follows: Figure 1 As shown, it includes:

[0037] 101. Based on the calculation formula of natural gas throttling theory, determine the cage structure corresponding to multiple target throttling flow values.

[0038] In this embodiment, when designing the cage structure, multiple target throttling flow rates can be set according to the actual throttling requirements. By setting multiple target throttling flow rates, the design range of the cage structure can be expanded to meet the needs under different operating conditions.

[0039] After determining multiple target throttling flow rates, the cage structure corresponding to these target throttling flow rates can be deduced by combining the natural gas throttling theory calculation formula.

[0040] It should be noted that, in this embodiment, the application of the natural gas throttling theoretical calculation formula is not specifically limited, as long as the formula has the condition of back-deriving the corresponding cage structure based on the target throttling flow rate value.

[0041] For example, the formula may include parameters such as the throttling flow rate value, the flow coefficient (which is related to the shape of the cage's orifice, Reynolds number, etc.), the effective area of ​​the orifice, the density of natural gas under a certain average state, and the isentropic index of natural gas (approximately equal to the adiabatic index). Thus, once the throttling flow rate value and other parameters are determined, the formula can be solved inversely to estimate the effective area of ​​the cage's orifice corresponding to each target throttling flow rate value.

[0042] Based on the effective area of ​​the throttling orifice and combined with the actual structural characteristics of the cage-type throttling valve, including but not limited to factors such as material, structural strength and space constraints, the size, shape and layout of the cage-type throttling orifice corresponding to each of the multiple target throttling flow values ​​are initially set, thereby generating multiple sets of different cage-type structures.

[0043] Therefore, it is clear that designing the cage sleeve structure is actually designing the shape, size, and layout of the throttling orifice of the cage sleeve. Once these factors are determined, that is, the cage sleeve structure is designed, the valve body, valve seat, and valve core structure of the cage sleeve throttling valve are obtained accordingly.

[0044] 102. Draw the actual flow relationship curves of the cage structure corresponding to multiple target throttling flow values ​​according to the preset drawing method.

[0045] In this step, the actual flow rate of each cage structure under different throttle valve openings can be obtained through various methods. Specifically:

[0046] The actual flow rate of each cage structure under different throttle valve openings can be determined by experimental methods alone; or, these flow rates can be calculated by simulation methods alone; or, a combination of experimental and simulation methods can be used to determine the actual flow rate of each cage structure under different throttle valve openings by calculating the average of the two results.

[0047] The different throttle valve openings should cover a sufficiently wide range of throttle valve openings in order to fully reflect the relationship between flow rate and opening degree.

[0048] Subsequently, for each cage structure, actual flow rate relationship curves were plotted based on the actual flow rate values ​​corresponding to different throttle valve openings and the corresponding throttle valve openings. This yields multiple sets of actual flow rate relationship curves between the cage structure and different throttle valve openings. In the curves, the horizontal axis represents each opening point of the throttle valve, while the vertical axis represents the actual flow rate value at the corresponding opening.

[0049] It should be noted that the above simulation method can be a fluid dynamics (CFD) simulation model or other simulation models that can calculate actual flow data; no specific limitations are made here.

[0050] 103. Use the curve comparison method to select the optimal actual flow relationship curve from multiple actual flow relationship curves.

[0051] In this step, to determine a better cage structure, the actual flow rate curves corresponding to multiple cage structures can be optimized to select the one with the best performance. This process helps identify which cage structures can exhibit superior performance in practical applications, providing a strong basis for subsequent optimization design.

[0052] When selecting the optimal actual flow rate curve, a curve comparison method can be used. This method can involve comparing the performance of multiple actual flow rate curves to select the optimal one; or it can compare the actual flow rate curve corresponding to each cage structure with its corresponding standard flow rate curve to quantitatively evaluate the degree of fit between the two, i.e., the curve comparison accuracy. After comparative analysis, the group with the highest curve comparison accuracy can be selected, and its corresponding actual flow rate curve can be determined as the optimal actual flow rate curve. This operation can find the cage structure that is closest to the ideal state and has the best performance, providing a clear direction and basis for subsequent optimization design.

[0053] The standard flow rate curves are plotted by obtaining the standard flow rates of each cage structure at different throttle valve openings and plotting them based on these standard flow rates and their corresponding openings. These standard flow rates can be derived from existing industry standards or obtained through theoretical calculation models. When using theoretical calculation models to obtain standard flow rates, it is necessary to ensure that all parameters in the model are normalized to guarantee the accuracy and reliability of the calculation results.

[0054] When the curve comparison method is used to compare the performance of multiple actual flow relationship curves, the implementation steps can be as follows:

[0055] 1. Establish multi-dimensional performance metrics to quantify the merits of each actual traffic relationship curve.

[0056] For example: Flow stability: the range of flow fluctuations (standard deviation or variance) at different opening degrees. Pressure drop characteristics: the matching between the pressure drop (ΔP) and flow rate of the throttle valve at a specific opening degree. Linearity: the linearity of flow rate change with opening degree (measured by goodness of fit R²). Response sensitivity: the slope of flow rate change with opening degree (e.g., the difference in sensitivity between high and low opening degree regions).

[0057] 2. Construct a comprehensive scoring model and calculate a comprehensive score for each curve by combining the performance index values ​​of each actual flow relationship curve.

[0058] 3. Directly compare the comprehensive scores of different cage structures and select the curve with the highest score as the optimal actual flow relationship curve.

[0059] It should be noted that this method can be used to perform data analysis and index calculation using MATLAB or professional fluid simulation software.

[0060] For example, suppose that the actual flow rate curve of a cage structure A has high flow rate stability under high pressure drop, while the curve of structure B has better linearity under low pressure drop. By using a comprehensive scoring model (e.g., assigning higher weight to pressure drop in high-pressure scenarios), the optimal curve that adapts to different operating conditions can be dynamically selected.

[0061] 104. Use simulation methods to determine the internal flow field simulation model, acoustic-vibration coupling simulation model, and erosion simulation model of the optimal cage structure corresponding to the optimal actual flow relationship curve.

[0062] 105. The internal flow field simulation model is used to simulate the internal flow field of the optimal cage structure, and the simulation results are obtained.

[0063] 106. The optimal cage structure was simulated using an acoustic-vibration coupling simulation model, and the simulation results were obtained.

[0064] 107. Use the erosion simulation model to perform erosion simulation on the optimal cage structure and obtain the erosion simulation results.

[0065] 108. Based on the simulation results of the internal flow field, the acoustic-vibration coupling simulation results, and the erosion simulation results, the optimal cage structure is optimized to obtain the target cage structure.

[0066] In steps 105-108, the internal flow field simulation results are used to characterize the velocity and pressure distribution of the fluid inside the cage-type throttle valve; the acoustic-vibration coupling simulation results are used to characterize the sound waves and vibrations generated by the optimal cage structure during operation; and the erosion simulation results are used to characterize the erosion of the optimal cage structure under different sand mass flow rates, different sand particle sizes, different fluid flow velocities, and different throttling pressure differences.

[0067] Among them, optimizing the optimal cage structure includes optimizing the material and structure of the cage, including the shape, size and layout of the throttling orifice.

[0068] In steps 104-105 of this embodiment, an internal flow field simulation model, an acoustic-vibration coupling simulation model, and an erosion simulation model can be established for the optimal cage structure corresponding to the optimal actual flow rate relationship curve. Different aspects of the optimal cage structure can be simulated using these models: the internal flow field simulation model simulates the internal flow field of the optimal cage structure; the acoustic-vibration coupling simulation model simulates the acoustic-vibration coupling of the optimal cage structure; and the erosion simulation model simulates the erosion of the optimal cage structure. Based on the simulation results, the optimal cage structure can be adjusted accordingly to obtain the target cage structure.

[0069] The simulation model of the internal flow field of the optimal cage structure corresponding to the optimal actual flow rate relationship curve can be determined by the following steps:

[0070] 1. Geometric Modeling: Based on the design parameters of the cage structure, use 3D modeling software (such as SolidWorks, CATIA, etc.) to create a geometric model of the cage, ensuring that the model is consistent with the expected structure.

[0071] 2. Mesh generation: Use CFD (Computational Fluid Dynamics) software (such as COMSOL Multiphysics) to mesh the geometric model, ensuring that the mesh density in key areas (such as fluid inlet, outlet and narrow channels) is high enough to improve simulation accuracy.

[0072] 3. Boundary condition setting: Set the boundary conditions of the flow field according to the actual working conditions, including inlet velocity, outlet pressure, fluid properties (such as density, viscosity, etc.) and wall conditions (such as no slip condition).

[0073] 4. Solver settings: Select a suitable turbulence model (such as the k-ε model or the SST k-ω model) to perform flow field simulation, set the convergence criterion and run the simulation to obtain data such as velocity and pressure distribution in the flow field.

[0074] The following steps can be taken to determine the optimal acoustic-vibration coupled simulation model of the optimal cage structure corresponding to the optimal actual flow rate relationship curve using simulation methods:

[0075] 1. Structural modal analysis: Modal analysis of the cage structure is performed using finite element analysis software (such as ANSYS Mechanical, Abaqus, etc.) to obtain the natural frequencies and mode shapes of the structure.

[0076] 2. Sound field modeling: Establish a sound field model in acoustic simulation software (such as LMS Virtual.Lab, COMSOL Acoustics module, etc.), taking into account the interaction between fluid and structure.

[0077] 3. Coupling settings: Couple the flow field simulation results with the acoustic vibration model, set the acoustic vibration coupling boundary conditions, and simulate the structural vibration caused by fluid flow and the resulting sound field.

[0078] 4. Simulation Operation: Run the acoustic-vibration coupling simulation to obtain the vibration response and sound field distribution of the structure, and analyze parameters such as sound pressure level and sound power.

[0079] In acoustic-vibration coupled simulation models, it is important to note that because they are coupled with the flow field simulation results, the input parameters of the flow field simulation model directly affect the results of the acoustic-vibration coupled simulation model. In other words, the data input of the internal flow field simulation model has a significant impact on the accuracy of the acoustic-vibration coupled simulation model.

[0080] The erosion simulation model of the optimal cage structure corresponding to the optimal actual flow rate relationship curve can be determined by the following steps using simulation methods:

[0081] 1. Particle property settings: Set the properties of solid particles in the fluid in the CFD software, including particle diameter, density, concentration and velocity distribution.

[0082] 2. Selection of erosion model: Select an appropriate erosion model (such as Finnie model, Oka model, etc.) and define the interaction mechanism between particles and the wall.

[0083] 3. Simulation Operation: Run the erosion simulation to simulate the impact and wear process of particles on the cage wall and obtain the erosion rate and erosion distribution of the wall.

[0084] Based on the above Figure 1As can be seen from the implementation method, the cage design method for a cage-type throttling valve under ultra-high pressure conditions provided by this invention can obtain the cage structure corresponding to multiple target throttling flow rates through the natural gas throttling theory calculation formula, thereby establishing a close mathematical relationship between the cage structure design and the required throttling flow rate. This not only improves the accuracy of the design but also enhances its feasibility. Next, multiple sets of actual flow relationship curves of the cage structures can be plotted. These curves intuitively show the flow variation law under each cage structure, providing a visual basis for subsequent optimization. On this basis, further optimization processing can be performed on the multiple sets of actual flow relationship curves to select the optimal actual flow relationship curve, thereby obtaining the optimal cage structure corresponding to the optimal actual flow relationship curve. Finally, simulation methods can be used to determine the internal flow field simulation model, acoustic-vibration coupling simulation model, and erosion simulation model of the optimal cage structure. Then, the internal flow field simulation model is used to simulate the internal flow field of the optimal cage structure, and the simulation results are used to characterize the velocity and pressure distribution of the fluid inside the cage-type throttle valve. At the same time, the acoustic-vibration coupling simulation model is used to simulate the acoustic-vibration coupling of the optimal cage structure, and the simulation results are used to characterize the sound waves and vibrations generated by the optimal cage structure during operation. Additionally, the erosion simulation model is used to simulate the erosion of the optimal cage structure, and the simulation results are used to characterize the erosion of the optimal cage structure under different sand mass flow rates, different sand particle sizes, different fluid velocities, and different throttling pressure differences. Finally, the optimal cage structure can be optimized based on the simulation results of the internal flow field, acoustic-vibration coupling, and erosion. This optimization includes optimizing the cage's material and structure, specifically the shape, size, and layout of the throttling orifice. Simulation allows for a detailed understanding of the optimal cage structure's operation during the design phase, leading to a comprehensive performance evaluation. This not only helps identify potential safety hazards in advance but also enables targeted optimization of the cage structure based on these hazards, ensuring that the optimized target cage structure achieves the desired effect when applied to the throttling valve.

[0085] Furthermore, as a response to Figure 1 Further refinement and extension of the illustrated embodiment, this invention also provides another cage sleeve design method for cage sleeve throttle valves under ultra-high voltage operating conditions, such as... Figure 2 As shown, the specific steps are as follows:

[0086] 201. Based on the calculation formula of natural gas throttling theory, determine the cage structure corresponding to multiple target throttling flow values.

[0087] The implementation method of step 201 is the same as that of step 101, and can achieve the same technical effect and solve the same technical problem, so it will not be repeated here.

[0088] 202. Draw the actual flow relationship curves of the cage structure corresponding to the multiple target throttling flow values ​​according to the preset drawing method.

[0089] In this embodiment, it is preferable to rely solely on simulation methods to calculate the actual flow rate of each cage structure under different throttle valve openings, which can greatly improve efficiency.

[0090] Subsequently, for each cage structure, actual flow rate relationship curves were plotted based on the actual flow rate values ​​corresponding to different throttle valve openings and the corresponding throttle valve openings. This yields multiple sets of actual flow rate relationship curves between the cage structure and different throttle valve openings.

[0091] In the graph, the horizontal axis represents the various opening points of the throttle valve, while the vertical axis represents the actual flow rate at the corresponding opening.

[0092] 203. Use the curve comparison method to select the optimal actual flow relationship curve from multiple actual flow relationship curves.

[0093] In this embodiment, the standard flow rate of each cage structure under different throttle valve openings is first obtained. Then, based on these standard flow rates and their corresponding throttle valve openings, a standard flow rate relationship curve for each cage structure is plotted. Next, each actual flow rate relationship curve is compared with its corresponding standard flow rate relationship curve, and the curve comparison accuracy of each actual flow rate relationship curve is calculated. Finally, the actual flow rate relationship curve with the highest curve comparison accuracy is selected as the optimal actual flow rate relationship curve. This process not only ensures a high degree of agreement between the selected curve and the ideal state but also provides a clear direction and basis for subsequent optimization design.

[0094] In the standard flow relationship curve of each cage structure, the horizontal axis represents the opening point of the throttle valve, and the vertical axis represents the standard flow value of each cage structure at the corresponding opening.

[0095] 204. Use simulation methods to determine the internal flow field simulation model, acoustic-vibration coupling simulation model, and erosion simulation model of the optimal cage structure corresponding to the optimal actual flow relationship curve.

[0096] 205. The internal flow field simulation model is used to simulate the internal flow field of the optimal cage structure, and the simulation results are obtained.

[0097] 206. The optimal cage structure was simulated using an acoustic-vibration coupling simulation model, and the simulation results were obtained.

[0098] 207. Erosion simulation model was used to simulate the erosion of the optimal cage structure and the erosion simulation results were obtained.

[0099] 208. Based on the simulation results of the internal flow field, the simulation results of acoustic-vibration coupling, and the simulation results of erosion, the optimal cage structure is optimized to obtain the target cage structure.

[0100] In steps 204-208 of this embodiment, the internal flow field simulation model can be used to simulate the internal flow field of the optimal cage structure to obtain the internal flow field simulation results. The internal flow field simulation results are used to characterize the velocity distribution and pressure distribution of the fluid inside the cage-type throttle valve.

[0101] Simultaneously, the optimal cage structure is simulated using an acoustic-vibration coupling simulation model to obtain the acoustic-vibration coupling simulation results. These results are used to characterize the sound waves and vibrations generated by the optimal cage structure during operation.

[0102] The optimal cage structure was also simulated using an erosion simulation model. The erosion simulation results were used to characterize the erosion of the optimal cage structure under different sand mass flow rates, different sand particle sizes, different fluid flow velocities, and different throttling pressure differences.

[0103] Finally, the optimal cage structure was optimized based on the simulation results of the internal flow field, the acoustic-vibration coupling simulation results, and the erosion simulation results, and the target cage structure was obtained.

[0104] Specifically, based on the internal flow field simulation results, the throttling orifice layout of the optimal cage structure can be adjusted to optimize the velocity and pressure distribution of the fluid; based on the acoustic-vibration coupling simulation results, the shape and size of the throttling orifice of the optimal cage structure can be adjusted to reduce the generation of sound waves and vibrations; based on the erosion simulation results, the material of the optimal cage structure can be adjusted to improve erosion resistance; finally, the optimized throttling orifice layout, shape and size, and material can be integrated to form the target cage structure.

[0105] Example: 1. Adjust the throttle orifice layout based on the internal flow field simulation results:

[0106] Simulation results analysis: Through internal flow field simulation, it was found that the fluid velocity was too high in some areas inside the cage, resulting in large local pressure loss and the presence of vortex phenomena.

[0107] Optimization measures: The layout of the throttling orifices can be adjusted, for example, changing the orifice distribution from uniform to non-uniform, increasing the number of orifices or enlarging the orifice diameter in high-velocity regions, in order to balance the velocity and pressure distribution of the fluid.

[0108] For example, assuming the original design has throttling orifices uniformly distributed around the circumference of the cage, simulation results show that the fluid velocity is too high near the inlet. After optimization, the orifice density can be increased near the inlet while decreasing near the outlet, thereby improving the uniformity of the flow field.

[0109] 2. Adjust the shape and size of the throttling orifice based on the acoustic-vibration coupling simulation results:

[0110] Simulation results analysis: Acoustic-vibration coupling simulation shows that certain orifice shapes (such as circles) will generate strong sound waves and vibrations at specific flow velocities, resulting in noise levels exceeding the standard.

[0111] Optimization measures: Change the shape of the throttling orifice from circular to elliptical or streamlined, and adjust the size of the throttling orifice to reduce turbulence and vibration generated when the fluid passes through the throttling orifice.

[0112] For example, replacing a circular orifice with a diameter of 5mm with an elliptical orifice with a major axis of 6mm and a minor axis of 4mm resulted in a 15% reduction in noise levels and a significant decrease in vibration amplitude, according to simulation results.

[0113] 3. Adjust the cage material based on the erosion simulation results:

[0114] Simulation results analysis: Erosion simulation shows that certain areas of the cage sleeve (such as the edge of the throttling hole) are severely worn due to the impact of high-speed particles, resulting in a shortened service life.

[0115] Optimization measures: Select materials with higher hardness or better erosion resistance, such as replacing ordinary carbon steel with hard alloy or ceramic coating materials.

[0116] For example, changing the cage sleeve material from 45# steel to WC-Co cemented carbide resulted in a 50% reduction in erosion rate, significantly improving the service life of the cage sleeve.

[0117] 209. Further optimization of the simulation models of the target cage structure and internal flow field, acoustic-vibration coupling simulation model, and erosion simulation model.

[0118] In this embodiment of the invention, a field information feedback system may be introduced, which includes a data monitoring module, a data feedback module, and a data analysis module.

[0119] The data monitoring module is used to monitor the actual operating data of the cage-type throttle valves deployed in actual application scenarios in real time using monitoring equipment. The operating data includes the internal flow field, acoustic-vibration coupling, and erosion.

[0120] After monitoring, the data feedback module can be used to feed back the actual operational data and store it in the database. Furthermore, the data analysis module can analyze the actual operational data stored in the database to obtain the analysis results.

[0121] Meanwhile, the optimized cage structure obtained by the UHV natural gas cage-type throttle valve design method described in this embodiment of the invention will be continuously monitored by the field information feedback system after it is put into actual use.

[0122] Furthermore, to ensure accurate monitoring of each cage-type throttle valve, this field information feedback system can be deployed at each throttle valve location in the field. This distributed deployment method enables comprehensive coverage and real-time monitoring of the operating status of each throttle valve, ensuring timely detection and handling of potential problems and guaranteeing the safe and stable operation of the entire system.

[0123] To further improve the performance of the target cage structure, the execution subject of this invention, namely the cage design system, can interact with on-site information feedback to obtain actual operating data of the deployed cage-type throttle valves. This allows for more in-depth optimization by combining the feedback data with actual operating data. In other words, the optimization work is expanded from simple simulation and theoretical calculations to the collection and analysis of actual on-site operating data. This actual operating data is obtained through real-time monitoring of the cage-type throttle valve's operation via an on-site information feedback system, including key indicators such as internal flow field conditions, acoustic-vibration coupling, and erosion.

[0124] By thoroughly analyzing this actual operational data, the target cage structure can be further adjusted and optimized to obtain an optimized cage structure, ensuring that it better adapts to field conditions. This step not only enhances the practicality and reliability of the optimized cage structure but also provides strong support for its superior performance in practical applications.

[0125] It is important to note that prior to obtaining the target optimized cage structure, this embodiment of the invention has not yet involved specific physical applications. Therefore, the actual operating data of the cage-type throttle valve monitored by the field information feedback system does not originate from the target optimized cage structure ultimately determined in this embodiment. This data actually comes from cage-type throttle valves that have already been put into use. Nevertheless, this actual operating data still has valuable reference value. It can reflect some actual construction characteristics, operating environment, and potential problems on site, thus providing useful guidance and reference for obtaining the target optimized cage structure, ensuring that the final target optimized cage structure not only meets the theoretical design requirements but also better adapts to the actual on-site conditions.

[0126] It is worth noting that, because the on-site information feedback system can continuously collect actual operating data of the cage-type throttle valve, after initially determining the target optimized cage structure, the target optimized cage structure can be iteratively optimized again using subsequent feedback operating data. The aim is to gradually approach a more ideal cage structure through continuous optimization.

[0127] To prevent the optimization process from getting stuck in an endless iterative loop, an iteration termination principle can be set. Specifically, when the change in the cage structure becomes extremely small in several consecutive iterations, i.e., less than a preset reasonable threshold, the iteration can be considered terminated. The setting of this threshold can take into account factors such as actual engineering needs, computational accuracy, and computational cost, to ensure that resources are not wasted by excessively pursuing minor improvements, nor are better solutions missed by terminating the iteration too early.

[0128] Furthermore, embodiments of the present invention can also optimize the internal flow field simulation model by combining the internal flow field conditions in the actual on-site operating data. Specifically, for the cage-type throttle valve corresponding to the actual on-site operating data, the internal flow field simulation model can be used to perform detailed simulation calculations to obtain the internal flow field simulation results.

[0129] The simulation results of the internal flow field are compared with the internal flow field conditions in the actual field operation data to calculate the deviation between the two. The parameters of the internal flow field simulation model are then adjusted based on the deviation to obtain an optimized internal flow field simulation model.

[0130] Meanwhile, the acoustic-vibration coupling simulation model can be optimized by combining the acoustic-vibration coupling situation in the actual on-site operating data. Specifically, for the cage-type throttle valve corresponding to the actual on-site operating data, the acoustic-vibration coupling simulation model can be used to perform detailed simulation calculations to obtain the acoustic-vibration coupling simulation results.

[0131] The acoustic-vibration coupling simulation results are compared with the acoustic-vibration coupling situation in the actual field operation data to calculate the deviation between the two. The parameters of the acoustic-vibration coupling simulation model are adjusted based on the deviation to obtain an optimized acoustic-vibration coupling simulation model.

[0132] In addition, the erosion simulation model can be optimized by combining the erosion situation in the actual field operation data. Specifically, the erosion simulation model can be used to perform detailed simulation calculations on the cage-type throttle valve corresponding to the actual field operation data in order to obtain the erosion simulation results.

[0133] The erosion simulation results are compared with the erosion situation in the actual field operation data to calculate the deviation between the two. The parameters of the erosion simulation model are then adjusted based on the deviation to obtain an optimized erosion simulation model.

[0134] In conclusion, the design method for the UHV natural gas cage-type throttle valve presented in this application can be implemented within an integrated design system. This system encompasses all simulation algorithms and calculation formulas required in the design process, ensuring the consistency and efficiency of the design. When any step requires incorporating actual field operating data for optimization, the system can establish a communication connection with the field information feedback system via an interface to acquire real-time field operating data and integrate it into the optimization process. This design approach not only improves the accuracy and practicality of the design but also ensures a close integration of the design process with actual field conditions, providing strong support for the optimized design of UHV natural gas cage-type throttle valves.
