Description

Technical Field

[0001] The present application relates to technical fields such as dynamic flow balancing valve design, and in particular to a method, device, electronic equipment and medium for determining parameters of a dynamic flow balancing valve. Background Art

[0002] In the heating system, when the water flow of some users changes (closed or adjusted), the resistance distribution of the system will change, causing the flow of other users to change accordingly. This hydraulic imbalance is randomly changing and dynamic, which will cause abnormal phenomena such as overcooling or overheating in users at different distances from the heat source, affecting the heating quality. This imbalance can only be solved by a dynamic balancing valve.

[0003] In the related technology, the automatic system is used to adjust the balance dynamically to ensure the quality of heating and achieve the purpose of energy saving and consumption reduction. The dynamic flow balancing valve is also called the self-powered flow balancing valve. It is characterized by not requiring external power and being able to rely on its own mechanical structure to automatically adapt to the changes in the pressure difference between the two ends of the control valve within a certain range to keep the flow unchanged. Unlike the mechanical dynamic flow balancing valve, the electronic regulating valve needs to know the real-time pipeline flow. When the pipeline flow does not match the target flow, the valve position is adjusted to achieve flow balance. However, the adjustment accuracy of the electronic regulating valve is poor, and the electronic regulating valve with higher accuracy mostly uses a more expensive flow meter to monitor the flow change, and the adjustment accuracy is closely related to the accuracy of the flow meter, so the cost of the electronic regulating valve is relatively high. The application of dynamic flow balancing valve is more extensive, but the design process of the dynamic flow balancing valve is usually directly tested in the physical field after the design and manufacturing are completed, which requires continuous processing, manufacturing and debugging, which is complicated and inefficient.

[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] In some examples, the dynamic flow balancing valve is also called a self-powered flow balancing valve. It is characterized by the fact that it does not require external power and can rely on its own mechanical structure to automatically adapt to changes in the pressure difference between the two ends of the control valve within a certain range to keep the flow unchanged. Unlike a mechanical dynamic flow balancing valve, an electronic control valve needs to know the real-time pipeline flow. When the pipeline flow does not match the target flow, the valve position is adjusted to achieve flow balance. However, the adjustment accuracy of the electronic control valve is poor, and the electronic control valve with higher accuracy mostly uses a more expensive flow meter to monitor flow changes, and the adjustment accuracy is closely related to the accuracy of the flow meter, so the cost of the electronic control valve is relatively high. The application of dynamic flow balancing valves is more extensive, but the design process of dynamic flow balancing valves is usually directly tested physically after the design and manufacturing are completed, which requires continuous processing, manufacturing and debugging, which is complicated and inefficient.

[0034] Based on this, the present application proposes a method for determining the parameters of a dynamic flow balancing valve. By utilizing the principle of fluid calculation and measurement and using a numerical simulation model, the parameters of the dynamic flow balancing valve are measured and verified from different dimensions to obtain a more optimal internal flow channel size of the dynamic flow balancing valve. This reduces the steps of physically conducting tests and debugging after the dynamic flow balancing valve is manufactured to determine the internal flow channel size, reduces actual equipment losses, greatly shortens the R&D cycle, and improves R&D efficiency.

[0035] Figure 1 It is a flow chart of a method for determining parameters of a dynamic flow balancing valve according to an embodiment of the present application.

[0036] As an example, Figure 1 As shown, the method for determining the parameters of the dynamic flow balancing valve includes:

[0037] S101, obtaining the size of the dynamic flow balancing valve, and constructing a fluid domain model of the dynamic flow balancing valve based on the size of the dynamic flow balancing valve.

[0038] S102, updating the fluid domain model based on the regulating valve distance configuration information, and obtaining the balancing valve diaphragm pressure difference information based on the updated fluid domain model, wherein the balancing valve diaphragm pressure difference information corresponds to the regulating valve distance configuration information one by one.

[0039] S103, when the balancing valve diaphragm pressure difference information meets the first preset condition, numerical simulation is performed based on the balancing valve inlet and outlet pressure difference configuration information to obtain flow information corresponding to the balancing valve inlet and outlet pressure difference information.

[0040] S104: When the flow information satisfies a second preset condition, determining the dynamic flow balancing valve size as a target dynamic flow balancing valve size.

[0041] For example, the present application may first preset the size of the dynamic flow balancing valve, and construct a fluid domain model of the dynamic flow balancing valve based on the preset size of the dynamic flow balancing valve. The fluid domain model can be understood as a model in which only the fluid is in the dynamic flow balancing valve, that is, the fluid area is extracted, and the fluid domain model is not a complete mechanical domain model. Figure 2 FIG. 1 is a schematic diagram of a fluid domain model, wherein the fluid domain model includes a plurality of flow cavity regions to be tested, wherein the flow cavity regions to be tested are determined based on the surface that can be contacted by the water flow entering the dynamic flow balancing valve. Figure 2 As shown, the flow chamber area to be measured may include: a first chamber area 1 on one side of the dynamic flow balancing valve diaphragm, a second chamber area 2 on the other side of the dynamic flow balancing valve diaphragm, a dynamic flow balancing valve inlet section area 3 and a dynamic flow balancing valve outlet section area 4. It should be noted that Figure 2 In the example shown, the first chamber area 1 is located above the dynamic flow balancing valve diaphragm, and the second chamber area 2 is located below the dynamic flow balancing valve diaphragm. Due to the different placement positions of the diaphragms, of course, the area below the dynamic flow balancing valve diaphragm can also be used as the first chamber area 1, and the area above the dynamic flow balancing valve diaphragm can be used as the second chamber area 2. It can be understood that one side of the dynamic flow balancing valve diaphragm is the first chamber area 1, and the other side is the second chamber area 2. The specific positions of the first chamber area 1 and the second chamber area 2 are not limited.

[0042] The fluid domain model may be a three-dimensional model corresponding to the flow domain of the dynamic flow balancing valve, which is established by using a model of a drawing software such as workbench, solidwork, or proe.

[0043] Exemplarily, after the fluid domain model is established, the fluid domain model is updated based on the control valve distance configuration information, wherein the control valve distance d is as follows: Figure 2 As shown, the regulating valve distance configuration information can be obtained by user selection or input. The fluid domain model is updated based on the regulating valve distance configuration information. It can be understood that each time the regulating valve distance is adjusted, the fluid domain needs to be re-extracted to construct the fluid domain model. The dynamic flow balancing valve is characterized in that it does not require external power and can rely on its own mechanical structure to automatically adapt to changes in the pressure difference at both ends of the control valve within a certain range to keep the flow rate unchanged. The present application obtains the balancing valve diaphragm pressure difference information corresponding to the regulating valve distance by continuously adjusting the regulating valve distance to verify whether the dynamic flow balancing valve can automatically adapt to changes in the pressure difference at both ends of the control valve within a certain range and keep the flow rate unchanged under the preset dynamic flow balancing valve size, that is, to determine whether the balancing valve diaphragm pressure difference information meets the first preset condition.

[0044] Exemplarily, when the balancing valve diaphragm pressure differential information meets the first preset condition, numerical simulation is performed based on the balancing valve inlet and outlet pressure differential configuration information to obtain flow information corresponding to the balancing valve inlet and outlet pressure differential information. The balancing valve inlet and outlet pressure differential configuration information can be obtained by user selection or input. It can be understood that the balancing valve inlet and outlet pressure differential is set to a numerical value, such as 100kpa, and the numerical simulation model automatically adjusts according to the set balancing valve inlet and outlet pressure differential. Numerical simulation is performed based on the balancing valve inlet and outlet pressure differential configuration information to obtain flow information corresponding to the balancing valve inlet and outlet pressure differential information. If the flow information meets the second preset condition, it means that the preset dynamic flow balancing valve size is a better size, the dynamic flow balancing valve size is determined to be the target dynamic flow balancing valve size, and the dynamic flow balancing valve is manufactured according to the target dynamic flow balancing valve size.

[0045] It should be noted that the pressure difference between the inlet and outlet of the balancing valve is inconsistent with the pressure difference on both sides of the balancing valve diaphragm. Figure 2 The setting of the diversion holes shown in FIG. Figure 2 The guide hole shown in the figure directs the inlet pressure to one side of the diaphragm ( Figure 2 The upper side is shown, and it can also be introduced into the lower side). In this case, the measured pressure values ​​of the inlet section area 3 of the dynamic flow balancing valve and the first chamber area 1 on one side of the dynamic flow balancing valve diaphragm are both p1, the measured pressure value of the second chamber area 2 on the other side of the dynamic flow balancing valve diaphragm is p2, and the measured pressure value of the outlet section area 4 of the dynamic flow balancing valve is p3. At this time, the pressure difference on both sides of the balancing valve diaphragm is p1-p2, and the pressure difference between the inlet and outlet of the balancing valve is p1-p3.

[0046] The present application utilizes the principle of a dynamic flow balancing valve and uses a numerical simulation method to perform fluid calculations to obtain simulation results of flow information and pressure difference information on both sides of a diaphragm. Based on the simulation results of the flow information and pressure difference information on both sides of the diaphragm, it is determined whether the size of the dynamic flow balancing valve meets the requirements, so as to obtain a better size of the dynamic flow balancing valve. This reduces the steps of physically conducting test and debugging after the dynamic flow balancing valve is manufactured to determine the internal flow channel size, reduces actual equipment loss, greatly shortens the R&D cycle, and improves R&D efficiency.

[0047] As an example, fluid dynamics software such as ANSYS FLUENT can be used to perform model pre-processing meshing on the above fluid domain model, select a turbulence model for the fluid flow state, and then import the model based on the divided mesh to perform calculations based on the law of conservation of mass, the law of conservation of momentum, and the law of conservation of energy, and finally obtain simulation calculation results. The simulation calculation results include flow information and pressure difference information on both sides of the diaphragm.

[0048] The method for calculating the pressure-velocity coupling is to first assume the pressure field for the drawn grid model, solve the velocity field according to the momentum equation, and then use the continuity equation to correct the pressure field. The corrected pressure field then updates the velocity field, and finally obtains the pressure value of the calculation area. When dividing the volume grid, different grids can be set for different flow cavity areas. For example, for the first chamber area 1 and the second chamber area 2, the size is set to 3.5×10 -4 m; for the inlet section area 3 and the outlet section area 4, the size is set to 7×10 -4 Furthermore, the quality of the volume mesh can be controlled by checking the orthogonal parameters of the volume mesh finally generated based on the above-mentioned divided mesh.

[0049] As an example, Figure 3 As shown, before updating the fluid domain model based on the regulating valve distance configuration information, the method for determining parameters of the dynamic flow balancing valve further includes:

[0050] S301, determining a target flow value based on a fluid domain model.

[0051] S302: When the target flow value is a required flow value, a target pressure difference of the balancing valve diaphragm is obtained based on the target flow value.

[0052] The target pressure difference is associated with the first preset condition, and the target flow value is the balancing valve flow corresponding to the case where the dynamic flow balancing valve is in a fully open state and the balancing valve inlet and outlet pressure difference is the first preset pressure difference.

[0053] Exemplarily, before updating the fluid domain model based on the regulating valve distance configuration information, a quantitative calculation is performed based on the constructed fluid domain model to determine the target flow value of the dynamic flow balancing valve. It can be understood that the target flow value is the balancing valve flow corresponding to the dynamic flow balancing valve being in a fully open state and the pressure difference between the inlet and outlet of the balancing valve being a first preset pressure difference. The dynamic flow balancing valve can be fully opened in advance, that is, the fluid domain model can be constructed when the opening is 100%. Based on the fluid domain model, when determining the target flow value, the front and rear pressure difference of the numerical simulation model can be directly set to 100kpa, and the numerical simulation model will automatically perform simulation according to the set front and rear pressure difference to obtain the target flow value.

[0054] For example, the target flow value can also be understood as the index value required by the user. If the target flow value obtained by the above calculation does not meet the flow value required by the user, the size of the dynamic flow valve is readjusted and the step of constructing the fluid domain is returned. When the target flow value is the required flow value, the target pressure difference of the balancing valve diaphragm is obtained based on the target flow value.

[0055] For example, the target pressure difference of the balancing valve diaphragm can be calculated by the following formula:

[0056]

[0057] Among them, Q is the target flow value, k is the flow coefficient, which is only related to the opening, A is the opening cross-sectional area, and Δp is the target pressure difference of the balancing valve diaphragm. The target flow value Q is obtained through the above steps. k is only related to the opening. When the opening is 100%, k is known. The opening cross-sectional area is one of the parameters of the dynamic flow balancing valve and is a known quantity. The target pressure difference Δp of the balancing valve diaphragm is obtained through the above formula.

[0058] It should be noted that when the fluid medium is constant, k is only related to the opening. When the valve reaches a certain opening, the k value is approximately unchanged. To keep the flow rate Q unchanged, it is only necessary to ensure The product of remains unchanged.

[0059] After obtaining the target pressure difference Δp of the balancing valve diaphragm, the pressure difference △p1 on both sides of the diaphragm corresponding to the regulating valve distance d is calculated by adjusting the regulating valve distance d. Each time the regulating valve moves a distance, there is a corresponding pressure difference value △p1. For example, multiple pressure differences on both sides of the regulating valve diaphragm △p1, △p2, △p3, △p4, etc. are obtained. It should be noted that each time the regulating valve distance d is adjusted, the fluid domain needs to be updated according to the regulating valve distance d, and the pressure difference information of the balancing valve diaphragm is obtained based on the updated fluid domain model.

[0060] As an example, Figure 4 As shown, the fluid domain model includes multiple flow cavity areas to be measured, and the pressure difference information of the diaphragm of the balancing valve is obtained based on the updated fluid domain model, including:

[0061] S401, based on the updated fluid domain model, obtaining a pressure cloud map of the updated fluid domain model, wherein the pressure cloud map represents the pressure information of multiple flow cavity regions to be tested.

[0062] S402, obtaining the balancing valve diaphragm pressure difference information based on the pressure cloud map.

[0063] Exemplarily, the regulating valve distance is adjusted, the fluid domain model is updated, and the updated fluid domain model is subjected to model pre-processing meshing, fluid flow state selection, and other operations. The fluid flow state selection may select a turbulence model, set the inlet mass flow rate and outlet pressure conditions of the fluid domain model, and obtain a pressure cloud map of the updated fluid domain model. The pressure cloud map represents the pressure information of multiple flow cavity areas to be measured.

[0064] For example, the regulating valve distance d is selected as 2.5 mm as a demonstration, and the pressure cloud diagram obtained is as follows: Figure 5As shown in the figure, the areas with different grayscales represent different pressures, and the dark gray represents the low-pressure area. Thus, the pressure values ​​on both sides of the diaphragm can be obtained from the pressure cloud map, thereby determining the pressure difference △p1 on both sides of the diaphragm.

[0065] For example, the regulating valve distance d is adjusted, and the pressure difference on both sides of the diaphragm corresponding to each distance d is recorded. Each time the regulating valve is adjusted, the pressure difference on both sides of the diaphragm is recorded once, and the pressure differences on both sides of the diaphragm △p1, △p2, △p3, △p4, etc. can be obtained. The pressure p1 of the first chamber area 1 on one side of the dynamic flow balancing valve diaphragm and the pressure p2 of the second chamber area 2 on the other side of the dynamic flow balancing valve diaphragm can be obtained by subtracting them to obtain the pressure difference on both sides of the diaphragm.

[0066] As an example, Figure 6 As shown, the pressure difference information of the balancing valve diaphragm is obtained based on the pressure cloud diagram, including:

[0067] S601, obtaining first pressure information corresponding to the first chamber area and second pressure information corresponding to the second chamber area based on the pressure cloud map.

[0068] S602: Obtaining the balancing valve diaphragm pressure difference information based on the first pressure information and the second pressure information, wherein the balancing valve diaphragm pressure difference includes the difference between the first pressure and the second pressure.

[0069] Exemplarily, the plurality of flow chamber regions to be measured include a first chamber region on one side of the dynamic flow balancing valve diaphragm and a second chamber region on the other side of the dynamic flow balancing valve diaphragm. There are two ways to set the flow guide hole, such as Figure 2 A setting mode is shown, under this setting mode, the measured pressure values ​​of the inlet section area 3 of the dynamic flow balancing valve and the first chamber area 1 on one side of the dynamic flow balancing valve diaphragm are both p1, the measured pressure value of the second chamber area 2 on the other side of the dynamic flow balancing valve diaphragm is p2, and the measured pressure value of the outlet section area 4 of the dynamic flow balancing valve is p3. Based on the pressure cloud map, the first pressure information p1 corresponding to the first chamber area and the second pressure information p2 corresponding to the second chamber area are obtained. Based on the first pressure information and the second pressure information, the pressure difference information of the balancing valve diaphragm is obtained, and the pressure difference of the balancing valve diaphragm is p1-p2.

[0070] As an example, Figure 7 As shown, the pressure difference information of the balancing valve diaphragm is obtained based on the pressure cloud diagram, including:

[0071] S701, obtaining second pressure information corresponding to the second chamber area and third pressure information corresponding to the fourth chamber area based on the pressure cloud map.

[0072] S702, obtaining the balancing valve diaphragm pressure difference information based on the second pressure information and the third pressure information, wherein the balancing valve diaphragm pressure difference includes the difference between the second pressure and the third pressure.

[0073] Exemplarily, the multiple flow chamber areas to be measured include the second chamber area on one side of the dynamic flow balancing valve diaphragm, the fourth chamber area of ​​the outlet section of the dynamic flow balancing valve, and the flow guide hole or another setting method is adopted. When the flow guide hole is set to introduce the outlet section pressure into the other side of the diaphragm, the second pressure information p2 corresponding to the second chamber area and the third pressure information p3 corresponding to the fourth chamber area are obtained based on the pressure cloud map, and the pressure difference information of the balancing valve diaphragm is obtained based on the second pressure information and the third pressure information. At this time, the pressure difference of the balancing valve diaphragm is p2-p3. It can be understood that when the flow guide hole is set to introduce the outlet section pressure into either side of the diaphragm, the pressure on this side is the same as that on the fourth chamber area of ​​the outlet section of the dynamic flow balancing valve, both of which are p3, and the pressure on the other side of the dynamic flow balancing valve diaphragm that is not introduced is p2, so at this time, the pressure difference on both sides of the balancing valve diaphragm is p2-p3.

[0074] According to the above method, the regulating valve distance d is adjusted, and the pressure difference on both sides of the diaphragm corresponding to each distance d is recorded to obtain the pressure differences on both sides of the diaphragm △p1, △p2, △p3, △p4, etc. It is determined whether the pressure difference information of the balancing valve diaphragm meets the first preset condition.

[0075] As an example, the balancing valve diaphragm pressure difference information satisfies the first preset condition, including: when each pressure difference in the balancing valve diaphragm pressure difference information is equal to the target pressure difference, determining that the balancing valve diaphragm pressure difference information satisfies the first preset condition.

[0076] For example, the dynamic flow balancing valve is characterized by the fact that it does not require external power and can rely on its own mechanical structure to automatically adapt to changes in the pressure difference between the two ends of the control valve within a certain range to keep the flow constant. Among them, the following equation must be satisfied when the diaphragm is balanced:

[0077] k·ΔL=A m (p1-p2)

[0078] Where k is the spring stiffness, ΔL is the spring deformation, A m is the projected area of ​​the diaphragm surface.

[0079] It can be understood that the spring stiffness k and the diaphragm surface projection area Am in the above formula are both known quantities, and the spring automatically adjusts the spring deformation according to the pressure difference between p1 and p2. The dynamic flow balancing valve ensures that the flow rate remains unchanged within a certain pressure difference range, and the judgment standard is: △p=△p1.

[0080] Exemplarily, if the pressure differences Δp1, Δp2, Δp3, and Δp4 on both sides of the diaphragm are all equal to the target pressure difference Δp, it is determined that the pressure difference information of the diaphragm of the balancing valve meets the first preset condition.

[0081] When the balancing valve diaphragm pressure difference information meets the first preset condition, numerical simulation is performed based on the balancing valve inlet and outlet pressure difference configuration information to obtain flow information corresponding to the balancing valve inlet and outlet pressure difference information. For example, the balancing valve inlet and outlet pressure difference configuration information is adjusted, and the digital simulation model automatically performs numerical simulation according to the configured balancing valve inlet and outlet pressure difference to obtain flow information corresponding to the balancing valve inlet and outlet pressure difference information, wherein the flow at the balancing valve inlet can be directly extracted as the flow information corresponding to the balancing valve inlet and outlet pressure difference information, and it is determined whether the flow information meets the second preset condition.

[0082] As an example, Figure 8 As shown, determining whether the flow information meets the second preset condition includes:

[0083] S801, obtaining a flow-pressure difference curve based on the configuration information of the inlet and outlet pressure difference of the balancing valve and the flow information corresponding to the inlet and outlet pressure difference information of the balancing valve.

[0084] S802: Determine a starting pressure difference value and a reference flow value based on a flow-pressure difference curve.

[0085] S803: Determine whether the flow information meets a second preset condition based on the starting pressure difference value and the reference flow value.

[0086] Exemplarily, the flow-pressure differential curve is obtained based on the configuration information of the inlet and outlet pressure differential of the balancing valve and the flow information corresponding to the inlet and outlet pressure differential information of the balancing valve. Specific process: The inlet and outlet pressure differential of the balancing valve can be directly input into the software, and the numerical simulation model automatically performs numerical simulation to obtain the flow, and the input inlet and outlet pressure differential of the balancing valve is used as the horizontal coordinate, and the flow simulated by the model is used as the vertical coordinate to draw the curve. It should be noted that a curve is for a fixed opening value.

[0087] For example, Fig. 9 The flow-pressure differential curve shown in the figure shows that the flow-pressure differential that normally meets the characteristics of the dynamic balancing valve will tend to be stable, that is, no matter how the pressure differential between the inlet and outlet of the balancing valve changes, the flow remains within the preset error range. The starting pressure differential value and the reference flow value are determined according to the flow-pressure differential curve, where the starting pressure differential value is the pressure differential value at which the flow value on the flow-pressure differential curve can remain stable, for example, Fig. 9The flow-pressure differential curve corresponding to 100% opening is shown. At about 25Kpa, the flow-pressure differential curve begins to remain stable, and the starting pressure differential value is 25Kpa. Of course, this is just an example, and the software can directly obtain the starting pressure differential value. The reference flow value is the flow value corresponding to a pressure differential of 100kpa on the flow-pressure differential curve. Before drawing the flow-pressure differential curve, the pressure differential between the inlet and outlet of the balancing valve can be input as 100kpa to obtain the corresponding flow value. Of course, after obtaining the flow-pressure differential curve, the flow value corresponding to a pressure differential of 100kpa can be calculated using methods such as linear interpolation.

[0088] Exemplarily, after obtaining the startup pressure difference value and the reference flow value, it is determined whether the flow information meets the second preset condition based on the startup pressure difference value and the reference flow value.

[0089] As an example, judging whether the flow information meets the second preset condition based on the starting pressure difference value and the reference flow value includes: when the pressure difference is greater than or equal to the starting pressure difference value, if the error between the flow rate and the reference flow rate value is within a preset error range, determining that the flow information meets the second preset condition.

[0090] For example, the preset error range can be the national standard relative error of the dynamic flow balancing valve flow rate of 8%, the inlet and outlet pressure difference of the dynamic flow balancing valve is ΔP, and the starting pressure difference is ΔP 启动 , take the flow value of pressure 100Kpa as the reference flow value, record the reference flow value as Q 100Kpa , when the pressure difference is greater than or equal to the starting pressure difference value, that is, ΔP ≥ ΔP 启动 When the measured flow value Q 测 The following conditions are met:

[0091] (1-8%)·Q 100Kpa ≤Q 测 ≤(1+8%)·Q 100Kpa

[0092] This indicates that the obtained dynamic flow balancing valve size is the design parameter of the optimal dynamic flow balancing valve, and the dynamic flow balancing valve size is determined to be the target dynamic flow balancing valve size.

[0093] As an example, the method for determining parameters of a dynamic flow balancing valve further includes:

[0094] When the balancing valve diaphragm pressure difference information does not meet the first preset condition, and / or the flow information does not meet the second preset condition, and / or the target flow value is not the required flow value, adjust the size of the dynamic flow balancing valve and return to the step of constructing the fluid domain model of the dynamic flow balancing valve based on the dynamic flow balancing valve size.

[0095] Exemplarily, if the balancing valve diaphragm pressure difference information △p1, △p2, △p3, △p4, etc. is not equal to the target pressure difference △p, or if the flow information is not within the preset error range, or if the calculated target flow value is not the required flow value, the dynamic flow balancing valve size is readjusted and the step of constructing the fluid domain model of the dynamic flow balancing valve based on the dynamic flow balancing valve size is returned.

[0096] Exemplarily, the way to adjust the internal flow channel size may be to adjust the size of each component of the dynamic flow balancing valve, for example, by adjusting the opening cross-sectional area of ​​the valve core, the internal size of the valve body, the size of the regulating device, etc. After the adjustment, the numerical simulation calculation can be performed again according to the steps of returning to the steps of constructing the fluid domain model of the dynamic flow balancing valve, and re-measurement can be performed until the target flow value is the required flow value, the condition of △p=△p1 is satisfied, and the flow is within the preset flow error range.

[0097] As an example, after determining that the dynamic flow balancing valve size is the target dynamic flow balancing valve size, the parameter determination method of the dynamic flow balancing valve also includes: adjusting the opening of the dynamic flow balancing valve to a preset opening to verify whether the balancing valve diaphragm pressure difference information meets the first preset condition and whether the flow information meets the second preset condition when the target dynamic flow balancing valve size is at the preset opening.

[0098] For example, if the above conditions are met, after the target dynamic flow balancing valve size is obtained, the corresponding flow-pressure difference curve is calculated by rotating different openings, that is, the opening of the dynamic flow balancing valve is adjusted to a preset opening to verify whether the pressure difference information of the balancing valve diaphragm meets the first preset condition and the flow information meets the second preset condition when the target dynamic flow balancing valve size is at the preset opening. For example, the above experiment is conducted when the opening is 100%, and the preset opening can be 50%, 30%, 20%, etc., and other openings that are not 100%. Fig. 9 Taking the opening of 50% and 100% as examples, it can be seen that when the opening is 50% and 100%, the pressure difference at both ends of the dynamic flow balancing valve changes within a certain range, and the flow rate can be kept unchanged.

[0099] In this case, a flow error can be calculated for each rotation opening value, and by multiple measurements at different rotation opening values, it is determined that the flow error of the dynamic flow balancing valve in the working state is within a preset flow error range.

[0100] The present application establishes a fluid domain model to obtain calculation results, and obtains the target flow value and the pressure difference on both sides of the diaphragm based on the calculation results and the pressure cloud map, thereby adjusting the internal flow channel size of the dynamic flow balancing valve to ensure that the flow value of the dynamic flow balancing valve in the working state remains within the preset error range, thereby improving the control accuracy. Accordingly, the obtained internal flow channel size is the design parameter of the optimal dynamic flow balancing valve.

[0101] Fig.10 It is a flow chart of a dynamic flow balancing valve design and analysis method according to an embodiment of the present application.

[0102] like Fig.10 As shown, S1: determine the flow cavity area to be tested of the dynamic flow balancing valve, and establish a fluid domain model based on the flow cavity area to be tested. S2: perform quantitative calculation based on the fluid domain model to determine the target flow value (Kvs value) of the dynamic flow balancing valve. S3: calculate the pressure difference △p (target pressure difference) on both sides of the diaphragm of the dynamic flow balancing valve based on the determined target flow value. S4: calculate the pressure difference △p1 on both sides of the corresponding diaphragm by adjusting the distance of the regulating valve, and judge whether △p=△p1 is equal. If equal, execute S5. S5: draw the flow-pressure difference curve of the calculation result. If the flow value corresponding to the starting pressure difference value is greater than the preset error range, the flow channel size in this model can be determined to be the optimal value. If not, execute S6: if not, adjust the internal flow channel size, and update the fluid domain model based on the adjusted model, and return to the step of performing quantitative calculation based on the fluid domain model. S7: based on the optimal model, rotate different openings to calculate the corresponding flow-pressure difference curve, and return to the step of adjusting the distance of the regulating valve.

[0103] This application establishes a fluid domain model, utilizes the working principle of the incompressible fluid flow equation, and uses a numerical simulation method to perform fluid calculations to obtain simulation results of the target flow value and the pressure difference on both sides of the diaphragm. This reduces the steps of physically performing test and debugging after the dynamic flow balancing valve is manufactured to determine the internal flow channel dimensions, reduces actual equipment losses, and greatly shortens the research and development cycle.

[0104] The present application also proposes a parameter determination device for a dynamic flow balancing valve.

[0106] A construction module 1101 is used to obtain the size of a dynamic flow balancing valve and to construct a fluid domain model of the dynamic flow balancing valve based on the size of the dynamic flow balancing valve; a first obtaining module 1102 is used to update the fluid domain model based on the regulating valve distance configuration information, and to obtain the balancing valve diaphragm pressure difference information based on the updated fluid domain model, wherein the balancing valve diaphragm pressure difference information corresponds one-to-one to the regulating valve distance configuration information; a second obtaining module 1103 is used to perform numerical simulation based on the balancing valve inlet and outlet pressure difference configuration information when the balancing valve diaphragm pressure difference information satisfies a first preset condition, so as to obtain flow information corresponding to the balancing valve inlet and outlet pressure difference information; a determination module 1104 is used to determine that the dynamic flow balancing valve size is the target dynamic flow balancing valve size when the flow information satisfies a second preset condition.
