[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] like Figure 1-12 As shown, the present application relates to a multi-channel fluid valve and a control method thereof. Figure 2-4 As shown and Figure 8-10 As shown, the multi-channel fluid valve includes: a valve body 10; the valve body 10 is a key component in a fluid control system, used to control the flow of liquid, gas or other fluids. In the present application, it is used to control the circulation of liquid, and realize fluid control by opening and closing or adjusting the on-off of the flow channel.

[0024] At least one set of drive components 20 is relatively arranged on both sides of the valve body 10 along the first direction; the drive component 20 refers to a component that can provide a stable driving force, thereby ensuring a stable power output effect, and then ensuring the effect of driving other components to perform directional movement. By arranging the drive components 20 on both sides of the valve body 10, a good relative movement effect can be achieved, thereby providing a basis for good cooperation. Among them, the first direction refers to the horizontal direction.

[0025] At least one set of valve core components 30 are respectively connected to the output ends of the drive components 20, and the ends thereof are respectively arranged in the flow channel holes of the valve body 10; the valve core components 30 refer to components that match the valve body 10; by connecting the valve core components 30 to the drive components 20 and the valve body 10 respectively, a good matching effect can be achieved, thereby achieving a good valve body 10 control effect.

[0026] The driving assembly 20 drives the valve core assembly 30 to move in the first direction, and drives the end of the valve core assembly 30 to move away from or against the flow channel hole of the valve body 10, so that the hole position of the inner cavity of the valve body 10 is opened or closed. The valve core assembly 30 and the driving assembly 20 are arranged on both sides of the valve body 10, respectively, and the driving assembly 20 controls the valve core assembly 30 to cooperate with the valve body 10, thereby controlling the opening or closing of the hole position in the valve body 10, thereby realizing the opening and closing of the flow channel, and finally realizing the precise control effect of the inflow and outflow of the solvent.

[0027] This application can achieve independent control of multiple valves through CNC technology, improving the accuracy and flexibility of fluid control. CNC technology: realizes independent and precise control of multi-channel valves, overcoming the limitations of traditional manual or electromagnetic control. Screw propulsion: uses the screw propulsion mechanism to realize the opening and closing of the valve, providing a reliable mechanical operation method. Flexible configuration: The CNC system can be flexibly programmed to meet different fluid control needs.

[0028] From the above description, it can be seen that the present application achieves the following technical effects: In the embodiment of the present application, an independent driving method is adopted, and the valve core assembly 30 is driven to move in a directional manner along the first direction by the driving assembly 20, and the end of the valve core assembly 30 is driven to move away from or against the flow channel hole of the valve body 10, so that the hole position of the inner cavity of the valve body 10 is opened or closed, thereby achieving the purpose of distributed driving of the valve core 302, thereby achieving the technical effect of improving the driving accuracy and stability, and further solving the problem that the existing multi-channel fluid valve control usually relies on manual operation or a simple electromagnetic operation mechanism, and has many limitations: first, the manual control method is not only inconvenient to operate, but also prone to misoperation due to human factors, thereby affecting the safety and stability of the system; secondly, these control methods are insufficient in accuracy and flexibility, and it is difficult to cope with complex, multi-threaded fluid distribution and switch adjustment requirements, and cannot meet the requirements of modern industry for independent design and precision control; and, when facing multi-channel fluid valves, traditional electromagnetic control systems are difficult to achieve fast response and high-frequency normally open and normally closed operation, which limits the efficiency and applicability of the system. Technical problems.

[0029] Furthermore, it also includes: a main controller (not shown), the main controller is electrically connected to at least one of the drive components 20, and the main controller is used to send a control signal to control the action of the drive component 20. It can be understood that by providing a main controller, the control accuracy of the drive component 20 can be improved, thereby providing a guarantee for accurate electrical control.

[0030] Preferably, the main controller is MCU, SOC or PLC. It is understandable that a variety of main controller models can be selected, thereby achieving the effect of flexible use, and further achieving the effect of improving market competitiveness.

[0031] Furthermore, the driving assembly 20 comprises: a driving component 201 electrically connected to the main controller, and a first connecting member 202 connected to the valve core assembly 30 is arranged on the output shaft of the driving component 201; The main controller sends a control signal to control the driving component 201 to perform a preset action, and the driving component 201 controls the first connecting member 202 to move according to the control signal, and the first connecting member 202 synchronously drives the valve core assembly 30 to move. It can be understood that by driving the first connecting member 202 to move by the driving component 201, a good power transmission effect can be achieved, and a stable power transmission effect can be ensured.

[0032] Of course, the driving component 201 can be a motor, and the main controller controls the running state of the motor through the driver or directly. According to the output signal of the main controller, such as voltage, frequency, PWM signal, the motor performs corresponding actions, such as rotation, speed regulation, and positioning.

[0033] The first connecting member 202 may be a coupling, which is used to connect two shafts to transmit torque and rotational motion, and can achieve a good connection effect between components, thereby ensuring a good power transmission effect.

[0034] Further, a support assembly 40 connected to one end of the drive assembly 20 is disposed on the periphery of the valve core assembly 30 along the first direction, and the support assembly 40 includes: a connecting plate 401 connected to the output end of the drive assembly 20, a plurality of support members 402 are disposed on the connecting plate 401 away from the side of the drive assembly 20 and along the first direction, a plurality of the support members 402 are disposed around the connecting plate 401, and a plug plate 403 is disposed at the bottom of the plurality of the support frames; The connecting plate 401, the plurality of supporting members 402 and the plugging plate 403 are combined to form a support frame with four sides open. It is understandable that the connecting plate 401, the plurality of supporting members 402 and the plugging plate 403 are assembled to form a support frame with four sides open, thereby ensuring a good assembly effect of other subsequent components; at the same time, it can also ensure good structural strength.

[0035] Further, the valve core assembly 30 includes: a second connecting member 301 connected to the first connecting member 202 along the first direction, the second connecting member 301 is connected to the plugging plate 403, a valve core 302 penetrating the plugging plate 403 is arranged at one end of the second connecting member 301 away from the first connecting member 202, and a stopper 303 connected to the plugging plate 403 is arranged at the periphery of the second connecting member 301. It can be understood that a good assembly molding effect of the valve core 302 can be achieved.

[0036] like Figure 5-6 As shown and Figure 11-12 As shown, the valve body 10 is provided with a first flow channel 101 perpendicular to the first direction and located in the same plane, at least one set of second flow channels 102 are arranged opposite to each other along the first direction on both sides of the first flow channel 101, the valve core components 30 are arranged in the second flow channels 102 respectively, and the second flow channels 102 are provided with a third flow channel 103 perpendicular to the first direction. It can be understood that a good flow channel molding effect can be achieved, thereby providing a guarantee for the circulation of the solvent.

[0037] Specifically, the first flow channel 101 is the main solvent flow channel, which can achieve the effect of transporting the external solvent into the valve body 10; the second flow channel 102 cooperates with the valve core assembly 30 to achieve the opening and closing state of the flow channel, thereby achieving a good state control effect; the third flow channel 103 is the solvent output flow channel, which can achieve the effect of directional flow of the solvent.

[0038] Furthermore, the second flow channel 102 is provided with an annular limiting portion 104 on the side close to the first flow channel 101, and the diameter of the annular limiting portion 104 gradually decreases from the outside to the inside along the length direction of the second flow channel 102. It can be understood that by providing the annular limiting portion 104 in the second flow channel 102 and close to the side of the first flow channel 101, a good limiting effect can be achieved, thereby preventing the valve core 302 from over-travel, and finally achieving a good protection effect; at the same time, the shape of the annular limiting portion 104 is set to be gradually reduced from the outside to the inside along the length direction of the second flow channel 102, which can improve the sealing effect, thereby ensuring that when the valve core 302 is closed, the solvent will not leak, thereby affecting the solvent inlet and outlet effect of the valve body 10.

[0039] Preferably, the annular limiting portion 104 is in an oblique cone shape, which can achieve a good matching effect and a good sealing effect.

[0040] It should be noted that, in order to achieve a good matching effect, the top of the valve core 302 matches the annular limiting portion 104, thereby ensuring a good matching effect.

[0041] Further, the number of at least one group of valve core assemblies 30 is one group of valve core assemblies 30 or six groups of valve core assemblies 30; The number of the valve core assemblies 30 matches the number of the drive assemblies 20. It is understandable that by setting one or six groups of valve core assemblies 30, a flexible use effect can be achieved, thereby meeting the needs of various usage scenarios. Of course, it can also be set in two, three, four or more groups according to usage requirements, which is not limited in this application.

[0042] like Figure 1 As shown, when the number of the valve core components 30 is one group, the two valve core components 30 are respectively arranged on both sides of the valve body 10 along the first direction, and are respectively connected to the driving components 20; At least the periphery of the driving assembly 20 and the valve core assembly 30 is provided with a housing 50; The driving assembly 20 comprises: a driving component 201, a reducer 203 is arranged on the output shaft of the driving component 201, and the driving component 201 is electrically connected to the main controller; The main controller sends a control signal to control the driving component 201 to perform a preset action, and the driving component 201 controls the reducer 203 to act according to the control signal, and the reducer 203 drives the valve core assembly 30 to act synchronously. It can be understood that by adopting a structure of a set of valve core assemblies 30 and a set of driving assemblies 20, a large-caliber three-way valve can be assembled to achieve a good solvent inlet and outlet control effect.

[0043] It should be noted that in a servo motor or stepper motor system, the motor is usually equipped with an encoder or position sensor. The sensor signal is fed back to the controller, and the controller adjusts the motor's movement based on the feedback to achieve precise control.

[0044] The reducer 203 is installed on the output shaft of the motor to reduce the speed of the motor and increase the output torque. The reducer 203 is not directly connected to the controller. It is the mechanical transmission part of the motor and adjusts the output characteristics of the motor to meet the load requirements.

[0045] Through the reducer 203, the high speed of the motor can be converted into a low speed, high torque output suitable for practical applications, ensuring that the system can effectively drive the load.

[0046] Preferably, a protective member is also provided outside the housing 50, which can achieve good protection and connection with other components. The protective member can be an angle bracket.

[0047] like Figure 5 As shown, when the number of the valve core assemblies 30 is six, the valve core assemblies 30 are arranged in an array at intervals along the first direction on both sides of the valve body 10, and the valve core assemblies 30 are connected to the drive assemblies 20 respectively; A housing 50 is disposed around the valve body 10 , the drive assembly 20 and the valve core assembly 30 ; The housing 50 is provided with a through slot 60 located above the output end of the valve body 10; The output end of the valve body 10 is provided with a plurality of connectors 70, and the number of the connectors 70 matches the number of the valve core assemblies 30. It can be understood that by adopting the structural form of six sets of valve core assemblies 30 and six sets of drive assemblies 20, a six-way valve can be assembled to achieve a good multi-channel control effect.

[0048] The present application also relates to a multi-channel fluid valve control method, comprising the multi-channel fluid valve as described above; The following steps are also included: S101, obtaining preset parameter information of the driving component 20; wherein the parameter information includes: propulsion speed, position information and rotation angle; S102. Based on the parameter information and in accordance with a preset distributed control algorithm, control instructions are issued to control the drive components 20 to act separately. The drive components 20 drive the valve core components 30 to move away from or against each other in the valve body 10 according to preset requirements to control the opening or closing state of the corresponding flow channel.

[0049] Specifically, the preset parameter information of the driving component 20 is obtained; wherein the parameter information includes: propulsion speed, position information and rotation angle; The drive component is responsible for executing specific mechanical movements in the valve control system to achieve the positioning and movement of the valve core. The preset parameter information of the drive component includes: The propulsion speed indicates the speed at which the drive assembly moves. This parameter determines how fast the valve core moves, thus affecting the opening or closing speed of the flow channel. Precise control of the propulsion speed can ensure the stability and response speed of the fluid flow.

[0050] Position information is an accurate measurement of the current position of the drive component, usually obtained through a position sensor (such as a photoelectric encoder or a linear displacement sensor). Position information is used to monitor the position of the valve core in real time to ensure that it moves along the set trajectory within the valve body.

[0051] The rotation angle controls the rotation position of the valve core, thereby adjusting the opening of the flow channel and affecting the flow of the fluid.

[0052] Based on the parameter information and according to the preset distributed control algorithm, control instructions are issued to control the driving components to act separately, and the driving components respectively drive the valve core components to move away from or against each other in the valve body according to preset requirements to control the opening or closing state of the corresponding flow channel; Distributed control algorithm is a method of decomposing complex control tasks into multiple independent subtasks through decentralized computing and control. These subtasks are executed by multiple control units (usually embedded controllers or microprocessors) and coordinated through a network or bus system.

[0053] Preset distributed control algorithm: refers to the algorithm that has been defined in the system design stage, which calculates and issues control instructions in real time based on the preset parameter information of the drive components. The control instructions can independently control the action of each drive component to achieve precise positioning and movement of the valve core.

[0054] The control instructions are based on the propulsion speed, position information and rotation angle of the drive components. The distributed control algorithm generates control instructions to instruct each drive component to perform corresponding operations.

[0055] In the present application, the driving assembly is directly connected to the valve core assembly, and the valve core is controlled by controlling the action of the driving assembly.

[0056] Individual actions: Each drive assembly can independently perform a predetermined movement according to the instructions of the distributed control algorithm, allowing the system to flexibly control the movement of multiple valve core assemblies and ensure that each valve core assembly moves according to the set requirements within the valve body.

[0057] Under the action of the drive assembly, the valve core assembly can move away from or towards the valve seat in the valve body. When moving away, the flow channel is opened to allow fluid to pass; when the valve core assembly is against each other, the flow channel is closed to prevent the fluid from flowing. By precisely controlling these actions, the system can achieve precise control of the flow channel and achieve the purpose of regulating or completely closing the flow of fluid.

[0058] The drive assembly can change the state of the flow channel according to the needs of the fluid control system by precisely controlling the valve core.

[0059] When the drive assembly moves the valve core away from the valve seat, the flow passage is opened, allowing fluid to flow through. The flow rate in this state depends on the distance or rotation angle between the valve core and the valve seat.

[0060] Closed state: When the drive assembly presses the valve core against the valve seat, the flow channel is closed and the fluid is blocked from passing through. The sealing performance in the closed state is determined by the matching accuracy of the valve core and the valve seat.

[0061] According to an embodiment of the present invention, preferably, the control parameters are gradually adjusted through real-time collected data to adapt to different working conditions. For example, under different load or temperature conditions, the algorithm can automatically adjust the control strategy of propulsion speed and rotation angle.

[0062] Model Reference Adaptive Control (MRAC): Utilizes a reference model to define the desired system response and adjusts controller parameters in real time to make the system output close to the output of the reference model.

[0063] According to an embodiment of the present invention, preferably, redundant control unit: in a distributed control system, a redundant control unit is configured for each key component. Once a control unit fails, the redundant unit can immediately take over the task to ensure the continuity and reliability of the system.

[0064] Fault Detection and Isolation (FDI): Through real-time monitoring and diagnosis, the source of the fault in the system is quickly detected, and the faulty unit is automatically isolated to prevent it from affecting other parts. FDI technology can be achieved by analyzing abnormal sensor data and inconsistent actuator status.

[0065] Switching strategy: Design an intelligent switching strategy so that the system can automatically switch to a backup unit or take appropriate repair measures when a unit failure is detected. The switch should be as smooth as possible to avoid excessive impact on the normal operation of the system.

[0066] According to an embodiment of the present invention, preferably, model predictive control (MPC) predicts future states by using a mathematical model of the system and generates an optimal control strategy based on these predictions. The advantage of MPC is that it can handle multivariable control problems and can optimize control performance under the premise of satisfying constraints.

[0067] MPC continuously updates the prediction model through Receding Horizon Optimization to cope with the real-time changing system status. Each optimization will predict the system behavior over a period of time based on the latest status data and calculate a series of optimal control actions.

[0068] In MPC, physical constraints of the system (such as maximum thrust, minimum angle, etc.) can be added to ensure that the generated control strategy is feasible in actual operation. At the same time, MPC can take measures in advance when the system approaches the constraint conditions to prevent violation of the constraints.

[0069] According to an embodiment of the present invention, preferably, each control unit in a distributed control system usually operates independently of each other, and the optimization algorithm can introduce a collaborative control mechanism to enable each unit to share information and coordinate actions to achieve global optimization. For example, each drive component can coordinate movement through real-time communication to ensure synchronous operation of the valve core component.

[0070] Distributed Optimization decomposes the global optimization problem into multiple sub-problems, assigns them to different control units for independent solution, and then aggregates the results through the communication network to obtain the global optimal solution. Distributed optimization can effectively reduce the computing load and improve the response speed of the system.

[0071] Consensus algorithms are used to achieve global consistency in distributed control systems. For example, when multiple control units share the same state variable (such as valve opening), the consensus algorithm can ensure that each unit has the same estimate of the variable, avoiding asynchronous or contradictory control instructions.

[0072] According to an embodiment of the present invention, preferably, in a distributed control system, control tasks are usually executed by multiple units simultaneously, and by optimizing task scheduling, the efficiency of the system can be improved, and task conflicts and resource contention can be reduced. For example, critical tasks or emergency tasks can be scheduled first to ensure the real-time performance and reliability of the system.

[0073] Load balancing, by analyzing the load of each control unit and dynamically allocating tasks, makes the load of each unit more balanced and avoids overloading or idleness of some units. For example, the system can monitor the working status of each drive component in real time, reasonably allocate control tasks, and ensure the overall efficiency is optimal.

[0074] According to an embodiment of the present invention, preferably, in complex application scenarios, the system may need to switch control strategies according to different working modes (such as startup, normal operation, fault handling, etc.). The multi-mode control algorithm can automatically identify the current working state and switch to the most suitable control mode. For example, when a sudden load change is detected, the system can switch from normal mode to acceleration mode to quickly respond to demand changes.

[0075] Hybrid control strategy combines multiple control strategies (such as PID control, adaptive control, predictive control, etc.) to select the optimal strategy combination according to different control requirements. This hybrid strategy can flexibly respond to different working conditions and improve the adaptability and stability of the system.

[0076] According to an embodiment of the present invention, preferably, a hierarchical control architecture is used to divide the control system into multiple levels (such as a central control layer, a local control layer, and an execution layer), and control units at different levels are responsible for control tasks of different complexity. This hierarchical architecture can effectively reduce the computational load of the central control unit while ensuring the real-time performance of the system.

[0077] Edge computing: In a distributed control system, some computing tasks can be delegated to edge devices (such as embedded processors in drive components) for processing. This reduces the reliance on central servers and improves the system's response speed and reliability.

[0078] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
