Description

Technical Field

[0001] The present invention relates to the technical field of integrated production control and management of industrial valves, and in particular to an integrated production control and management platform for industrial valves. Background Art

[0002] As key equipment in industrial production, industrial valves are widely used in petrochemical, electric power, metallurgy, water treatment and other fields, and undertake important functions such as medium transportation, flow control and system safety assurance. Due to the complex use environment, the production process of valves has high requirements, including material selection, casting processing, assembly testing and other links, and the precision and quality requirements are extremely strict. With the diversification of industrial needs, users have put forward more and more customized requirements for the size, performance and materials of valves, which makes the complexity of the production process continue to increase. In recent years, the application of technologies such as the Internet of Things (IoT), big data, and artificial intelligence (AI) in the manufacturing industry has gradually become popular, providing new ideas for the integration of valve production control. By collecting equipment operation data, process parameters and environmental information in real time, enterprises can build a data-driven management model to achieve full-process monitoring and optimization of the production process. In addition, data analysis based on machine learning algorithms can assist enterprises in predicting potential problems and improving product quality and the initiative of equipment maintenance. At the same time, the intelligent control platform can also connect production data with the supply chain and sales system, thereby realizing full life cycle management from order generation to product delivery.

[0003] However, although technological development has provided many opportunities for the valve industry, in actual applications, valve quality inspection is usually a post-inspection of a single link, lacking real-time monitoring and problem feedback mechanisms, resulting in the inability to trace quality problems and low rework efficiency. There is a lack of accurate assessment of the time of each link in the production cycle (such as casting, processing, assembly, etc.), resulting in inaccurate delivery cycle predictions, affecting customer satisfaction, and the data in the production process are mostly scattered in various links, making it impossible to form integrated transparent management and difficult to quickly respond to customer customization needs. Summary of the invention

[0004] The purpose of the present invention is to propose an integrated platform for industrial valve production management and control in order to solve the problems that valve quality inspection is usually a single-link post-inspection, lacks real-time monitoring and problem feedback mechanism, resulting in the inability to trace quality problems and low rework efficiency, lacks accurate assessment of the time of each link in the production cycle, resulting in inaccurate delivery cycle prediction, affecting customer satisfaction, and the data in the production process are mostly scattered in various links, unable to form integrated transparent management, and difficult to quickly respond to customer customization needs.

[0005] The object of the present invention can be achieved by the following technical solutions: An integrated platform for industrial valve production control, comprising: a demand acquisition analysis unit, an environment analysis unit and a demand detection unit;

[0006] The demand acquisition analysis unit is used to obtain the production and manufacturing standards of industrial valves. The production requirements of customers or users are obtained through the platform standard formulation program. The production requirements of industrial valves include valve type, material requirements, pressure level, flow characteristics, temperature range, connection method, sealing requirements, standards and certifications. The requirements are sorted and classified to ensure that each requirement item has a clear definition and marked with priority; then the production requirements of customers are obtained through the platform standard formulation program, and the corresponding industrial valves are selected according to the customer production requirements. The delivery cycle of the order is calculated to obtain the order delivery cycle T 总 ;

[0007] The environmental analysis unit is used to obtain production environment data and test environment data, and perform environmental analysis to obtain the environmental value HJZ; the demand detection unit is used to monitor the quality of industrial valves during the production process; specifically:

[0008] Detect and analyze the size of industrial valves to obtain the size value CCZ;

[0009] The sealing and airtightness strength of industrial valves are tested and analyzed to obtain the gas leakage Q1 and the valve stress σ1;

[0010] The functionality and thermal stress of industrial valves are tested and analyzed to obtain the flow coefficient Cv and thermal stress σr.

[0011] As a preferred embodiment of the present invention, it also includes a tracing unit;

[0012] The traceability unit is responsible for providing feedback and improvements on unqualified or deviating products. When the inspection unit finds that the valve does not meet the standards in terms of size, air tightness, functionality or thermal stress, the traceability unit marks the problem and feeds it back to the production line. The production line adjusts the parameters in the processing process based on the feedback to ensure that the valves produced subsequently meet the quality requirements.

[0013] As a preferred embodiment of the present invention, the order delivery cycle T is calculated. 总 The specific process is: the platform calls the program to call the unproduced quantity of the previous order and the corresponding industrial valve production standards, and calculates the production time for different industrial valve production standards:

[0014] The casting time of industrial valves with different production standards is calculated by the formula: Output casting time Tz, where Vz is the casting volume of the valve, Rz is the casting production capacity value; then calculate the processing time, through the formula: Output the processing time Tj, where Aj is the processing surface and Rj is the processing production capacity value of the factory; calculate the assembly time and output the assembly time Tp through the formula: Tp = p × Tb, where P is the valve complexity coefficient and Tb is the typical assembly time of a single preset standard valve; the valve complexity coefficient P is calculated according to the design complexity, number of components and valve size of the valve: obtain the number of components of the corresponding industrial valve and the type of industrial valve, and assign values ​​to different industrial valve types; then obtain the size of the corresponding industrial valve; output the valve complexity coefficient P through the formula: p = lbj × a1 + lxz × a2 + lc × a3, lbj is the number of components, lxz is the valve type value, lc is the valve size, and a1, a2 and a3 are the corresponding preset weights; then sum the calculated casting time Tz, processing time Tj and assembly time Tp to obtain the production time T of the corresponding industrial valve production standard; if there are n production standards, the production time of different industrial valve production standards is recorded as Ti;

[0015] Get the unproduced quantity w1 of the previous order and the number of unproduced types with different production standards z1; get the current order quantity w0 and the number of types zO within the order quantity; through the formula: Output order delivery cycle T 总 , w1 (i) ,w0 (i) Represents the quantity of each production standard in the respective order.

[0016] As a preferred embodiment of the present invention, the specific process of detecting and analyzing the industrial valve size to obtain the size value CCZ is as follows:

[0017] The dimensions of key parts are obtained through corresponding equipment, including valve outer diameter, inner diameter, aperture and roundness; through the established formula: Output dimension value CCZ, where e is a natural constant, Rw is the measured valve outer diameter, Rn is the measured valve inner diameter, yd is the measured valve roundness, and b1, b2 and b3 are their respective corresponding preset weight factors; then compare the calculated dimension value CCZ with the dimension range corresponding to the dimension in the required standard. If the dimension value CCZ exists in the corresponding dimension range, proceed to the next step of detection; if the dimension value CCZ does not exist in the corresponding dimension range and is less than the minimum value of the corresponding dimension range, the valve is re-cut and processed, and feedback is given to the production line to adjust the parameters in the processing process in time.

[0018] As a preferred embodiment of the present invention, the specific process of analyzing the sealing performance of industrial valves to obtain the gas leakage amount Q1 is as follows:

[0019] Install the valve to be tested on the air tightness test device, ensure that the inlet and outlet ports of the valve are sealed, and ensure that all valve interfaces and pipelines are tightly connected; use a highly sensitive gas leak detector to detect whether there is gas leakage on the valve surface, and conduct quantitative analysis of the leakage location; if gas leakage is detected, use the formula: Output gas leakage Q1, where V1 is the volume of the test device, ΔP1 is the change in gas pressure, and Δt1 is the time interval; compare the gas leakage Q1 with the gas leakage range corresponding to the size within the required standard. If the gas leakage Q1 does not belong to the corresponding gas leakage range, the valve is removed and marked as unqualified, and feedback is given to the production line to adjust the parameters in the processing process in time; conversely, if the gas leakage belongs to the corresponding gas leakage range, the airtight strength is tested to obtain the valve stress σ1.

[0020] As a preferred embodiment of the present invention, the specific process of testing the airtight strength to obtain the valve stress σ1 is as follows: testing is performed through the pressure resistance of the valve; the strength of the valve can be calculated through stress analysis; and the formula: Output valve stress σ1, P1 is the internal gas pressure, and h is the valve wall thickness.

[0021] As a preferred embodiment of the present invention, the specific process of obtaining the flow coefficient Cv by functional detection and analysis of the industrial valve is as follows:

[0022] According to the flow equation Output flow Q2, where ΔP2 is the pressure difference on both sides of the valve, and Cv is the flow coefficient of the valve; the flow coefficient is calculated based on the type and size of the valve: Cv = K2 × D2 2 Output flow coefficient Cv, K2 is a constant, D2 is the diameter of the valve; the flow coefficient Cv of the valve changes with the change of the opening; the relationship between the opening s and the flow is: Where Cv(s) is the flow coefficient at a certain opening; the flow coefficient Cv(s) is a function related to the opening s; in some cases, the flow coefficient Cv changes exponentially with the change of the opening s: Cv(s) = Cv max ×s α , where Cv max is the flow coefficient at maximum opening, α is an exponential factor, which varies according to the characteristics of the valve; the flow rates Q2 at different openings are compared with the standard range of opening flow rates obtained within the demand standard; if one or more opening flow rates Q2 do not fall within the standard range of opening flow rates, the traceability unit will feed back to the production line to adjust the parameters in the processing process in time; otherwise, the thermal stress is tested to obtain the thermal stress σr.

[0023] As a preferred embodiment of the present invention, the specific process of detecting the thermal stress to obtain the thermal stress σr is:

[0024] Measure the dimensional changes of valves at different temperatures; the linear thermal expansion coefficient β of valve materials and the elastic modulus E of the materials r Obtained through the demand standard, through the formula: σr=E r ×β×ΔT r Output thermal stress σr, ΔT r For temperature changes.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention realizes the full process management from customer demand acquisition, valve selection to order confirmation and production delivery cycle calculation through the synergy of demand acquisition analysis unit, environmental analysis unit, demand detection unit and traceability unit. Through standardized demand classification and priority labeling, the platform can accurately meet customer needs; at the same time, it uses formulaic calculation of casting, processing, assembly time, and evaluation of valve complexity coefficient to effectively improve the accuracy of production planning and order delivery efficiency. This systematic, data-driven management and control method not only improves production transparency, but also greatly enhances customer satisfaction and production flexibility.

[0027] 2. The environmental analysis unit acquires environmental indicator data in real time during the production and testing process, builds an environmental data portrait in combination with a polygonal radar chart, and compares and matches it with the preset standards, thus achieving accurate monitoring and dynamic control of the production and testing environments. Through standardized processing, image analysis, and formula calculation, it can quickly identify environmental anomalies and trigger automated control, effectively ensuring the stability and accuracy of the production and testing processes; at the same time, the control results are displayed in real time on the platform, providing transparent and efficient decision-making support for equipment operation and environmental management, further improving production quality and safety.

[0028] 3. The demand detection unit ensures that each valve meets the demand standards by accurately monitoring the key quality parameters of industrial valves such as size, sealing, airtightness, functionality and thermal stress. Using a variety of high-precision equipment and formulaic calculation methods, quality problems can be quickly identified and classified for processing: valves with unqualified dimensions are reprocessed or removed, valves with unqualified sealing and airtightness are adjusted through feedback mechanisms, and valves with abnormal functionality and thermal stress are optimized in design or improved in materials. Through dynamic monitoring and closed-loop feedback, the product qualification rate and stability of the production line are effectively improved, and the high performance and reliability of the valves are guaranteed.

[0034] See also Figure 1 As shown, an integrated platform for industrial valve production control includes: a demand acquisition analysis unit, an environment analysis unit, a demand detection unit and a traceability unit;

[0035] The demand acquisition and analysis unit is used to obtain the production and manufacturing standards of industrial valves. It obtains customer or user production requirements through the platform standard formulation program. The industrial valve production requirements include valve type, material requirements, pressure level, flow characteristics, temperature range, connection method, sealing requirements, standards and certifications, etc. The requirements are sorted and classified to ensure that each requirement item has a clear definition and marked with priorities (such as safety, stability, etc.);

[0036] The demand acquisition and analysis unit then selects the corresponding industrial valves according to the customer's production requirements and the user's production requirements; the industrial valves that meet the customer's production requirements or the user's production requirements are displayed on the platform display program, and the customer or user selects them; if the customer or user has selected the desired industrial valve, the order is confirmed, including the model, quantity, material, size and other detailed parameters of the selected valve; and the production standard and quantity of the corresponding industrial valve are obtained;

[0037] Calculate the order delivery cycle: The platform calls the program to retrieve the unproduced quantity of the previous order and the corresponding industrial valve production standards, and calculates the production time for different industrial valve production standards:

[0038] The casting (forging) time of industrial valves with different production standards is calculated by the formula: Output casting time Tz, where Vz is the casting volume of the valve, Rz is the casting production capacity, which is determined by the capacity of the casting (forging) factory; then calculate the processing (turning, milling, drilling, etc.) time, through the formula: Output the processing time Tj, where Aj is the processing surface, that is, the surface area that needs to be processed, and Rj is the processing production capacity of the factory; calculate the assembly time, and output the assembly time Tp through the formula: Tp = p × Tb, where P is the valve complexity coefficient, and Tb is the typical assembly time of a single preset standard valve; the valve complexity coefficient P is calculated based on the design complexity, number of components and valve size of the valve: obtain the number of components of the corresponding industrial valve and the type of industrial valve, and assign values ​​to different types of industrial valves; for example: such as gate valves, stop valves, etc., which are relatively simple and are assigned a value of 1, such as ball valves, regulating valves, butterfly valves, etc., which have relatively complex internal mechanisms. , then assign a value of 2; then obtain the size of the corresponding industrial valve. Large valves have more parts and are difficult to assemble; output the valve complexity coefficient P through the formula: p = lbj × a1 + lxz × a2 + lc × a3, lbj is the number of parts, lxz is the valve type value, lc is the valve size, a1, a2 and a3 are the corresponding preset weights; then sum the calculated casting time Tz, processing time Tj and assembly time Tp to obtain the production time T of the corresponding industrial valve production standard; if there are n production standards, and i = 1, 2, ..., n, then the production time of different industrial valve production standards is recorded as Ti

[0039] If the unproduced quantity of the previous order is w1 and the number of unproduced types with different production standards is recorded as z1; the current order quantity is w0 and the number of types within the order quantity is recorded as zO; through the formula:

[0040] Output order delivery cycle T 总 , w1 (i),w0 (i) Represents the quantity of each production standard in each order; the platform then calls the program to retrieve the order delivery cycle T 总 The environmental analysis unit is used to obtain production environment data and detection environment data for environmental analysis, and to compensate for the production and monitoring process. The specific process is as follows:

[0041] See also Figure 2 As shown, environmental indicator data in the production process are obtained, including but not limited to temperature data, humidity data, air pressure data, dust concentration and vibration data; similarly, environmental indicator data in the detection process are obtained, including but not limited to light data, noise data, dust concentration and air quality data; the obtained environmental data are then substituted into the polygonal radar map to obtain an environmental analysis map; the obtained data is first standardized and then substituted into the polygonal radar map, and each corner in the map is a different data type value, and the vertices of different data type values ​​​​substituted into the polygonal radar map are connected to obtain an environmental data portrait, which is compared with the preset environmental standard portrait, specifically:

[0042] Then obtain the area and angle value of each angle in the environmental data image map and the position of each angle in the environmental data image map; through the established formula: Output environment value HJZ, where JZ j is the angle value of the angle corresponding to j, and j = 1, 2, ..., M; WZ j is the position value of the angle corresponding to j in the environmental data image map, MJ is the area in the environmental data image map; WZ j By selecting the center point position origin in the environmental data portrait diagram and making an XZ coordinate system to obtain the position coordinate points of different positions; the corresponding angle position coordinate points in the environmental data portrait diagram are connected with the origin in the diagram to obtain the corresponding vectors, and the vectors of the corresponding angles are used as position values; then the obtained environmental value HJZ is matched with the standard interval corresponding to the preset environmental standard portrait, and the standard interval corresponding to the preset environmental standard portrait is recorded as the standard interval; if the environmental value HJZ does not belong to the environmental value HJZ, the corresponding equipment is controlled to be adjusted according to the standard area in the diagram; then the adjusted environmental value is calculated, and if the adjusted environmental value does not belong to the standard interval, the standard interval is inspected and displayed on the platform display program.

[0043] The demand detection unit is used to monitor the quality of industrial valves during the production process; specifically:

[0044] First, obtain the demand standards for industrial valves in production;

[0045] Detect the size of industrial valves: Use corresponding equipment (such as laser measuring instruments, projectors, profilometers, etc.) to obtain the size of key parts, including but not limited to the valve outer diameter (the diameter of the valve outside to ensure matching with the pipeline interface), inner diameter (the diameter of the valve cavity to ensure smooth flow of fluid channels), aperture and roundness (to ensure that the aperture and internal shape of the valve meet the design requirements to avoid affecting the valve sealing effect due to non-circular holes or size errors), etc.; through the established formula:

[0046] Output dimension value CCZ, where e is a natural constant, Rw is the measured valve outer diameter, Rn is the measured valve inner diameter, yd is the measured valve roundness, and b1, b2 and b3 are all corresponding preset weight factors; then compare the calculated dimension value CCZ with the dimension range corresponding to the dimension in the required standard. If the dimension value CCZ exists in the corresponding dimension range, the next step of detection is carried out; if the dimension value CCZ does not exist in the corresponding dimension range and is less than the minimum value of the corresponding dimension range, the valve is re-cut and fed back to the production line, and the parameters in the processing process (such as tool wear, cutting speed, coolant, etc.) are adjusted in time to ensure that the valve remains qualified in the next production cycle; if the dimension value CCZ does not exist in the corresponding dimension range and is greater than the maximum value of the corresponding dimension range, the valve is removed and marked as unqualified, and the traceability unit feeds back to the production line, and the parameters in the processing process are adjusted in time to ensure that the valve remains qualified in the next production cycle;

[0047] The sealing and airtightness strength test of industrial valves is as follows: install the valve to be tested on the airtightness test device, ensure that the inlet and outlet ports of the valve are sealed, and ensure that all valve interfaces and pipelines are tightly connected to avoid external air leakage; use a highly sensitive gas leak detector to detect whether there is gas leakage on the valve surface, and conduct quantitative analysis of the leakage position; if gas leakage is detected, use the formula: Output gas leakage Q1, where V1 is the volume of the test device, ΔP1 is the change in gas pressure, and Δt1 is the time interval; compare the gas leakage Q1 with the gas leakage range corresponding to the size within the required standard. If the gas leakage Q1 does not belong to the corresponding gas leakage range, the valve will be removed and marked as unqualified, and feedback will be given to the production line to adjust the parameters in the processing process in time to ensure that the valve remains qualified in the next production cycle; on the contrary, if the gas leakage belongs to the corresponding gas leakage range, the airtight strength will be tested: the pressure resistance of the valve will be tested; the strength of the valve can be calculated by stress analysis; through the formula: Output the valve stress σ1, where P1 is the internal gas pressure and h is the valve wall thickness. The calculated stress σ1 should be less than the yield strength σq of the corresponding valve material (similarly, obtained through the yield of the material in the required standard), and the safety factor ax should be considered; and σ1≤σq / ax should be satisfied. If σ1≤σq / ax is not satisfied, the valve will be removed and marked as unqualified, and the traceability unit will feed back to the production line to adjust the parameters in the processing process in time. Otherwise, if σ1≤σq / ax is satisfied, the next step of testing will be carried out.

[0048] The functionality and thermal stress of industrial valves are tested. Specifically, the functionality of industrial valves is mainly the relationship between flow rate and valve opening; it is described by the flow equation formula: Output flow Q2, where ΔP2 is the pressure difference on both sides of the valve, Cv is the flow coefficient of the valve, and the flow coefficient Cv is calculated based on the type and size of the valve:

[0049] Cv=K2×D2 2 Output flow coefficient Cv, K2 is a constant, depending on the valve type and the nature of the fluid, D2 is the diameter of the valve; it should be noted that the relationship between the valve opening and the flow rate can usually be approximated as a nonlinear relationship, especially at different positions in the control range; usually, the valve flow coefficient Cv will change with the change of the opening; the relationship between the opening s and the flow rate is: Where Cv(s) is the flow coefficient at a certain opening; the flow coefficient Cv(s) is a function related to the opening s; in some cases, the flow coefficient Cv will change exponentially with the change of the opening s: Cv(s) = Cv max ×s α , where Cv max is the flow coefficient at maximum opening, α is the exponential factor, usually between 0.5 and 2, and varies according to the characteristics of the valve; the flow rates Q2 of different openings are compared with the standard range of opening flow rates obtained within the required standard; if one or more opening flow rates Q2 do not fall within the standard range of opening flow rates, the traceability unit will feed back to the production line to adjust the parameters in the processing process in time; otherwise, the thermal stress is tested: the dimensional changes of the valve at different temperatures are measured; the linear thermal expansion coefficient β of the valve material and the elastic modulus E of the material r Obtained through the demand standard, through the formula: σr=E r ×β×ΔT r Output thermal stress σr, ΔT rThe valve is placed in a thermal cycle test chamber to perform periodic temperature changes (for example, from room temperature to high temperature, and then back to room temperature) to simulate the thermal stress fluctuations of the valve in the actual working environment and record them. If there is deformation or crack within the required standard, the traceability unit will feedback the problem and the designer will redesign or improve the material to improve its high-temperature stability.
