[0033] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0034] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0035] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0036] Figure 1 This is a schematic diagram of the structure of an intelligent regulating valve provided by an embodiment of the present disclosure. Figure 1 The intelligent regulating valve includes a first power supply, a second power supply, a power supply selection module, a main control module and an opening detection module; the first input end of the power supply selection module is connected to the first power supply, the second input end of the power supply selection module is connected to the second power supply, the control end of the power supply selection module is connected to the main control module, the output end of the power supply selection module is used to connect to the power supply end of the valve, the amplitude of the first power supply is smaller than the amplitude of the second power supply; the opening detection module is connected to the main control module, and the opening detection module is used to detect the opening of the valve.

[0037] In this embodiment, the power selection module has two input terminals, connected to a first power supply and a second power supply respectively. The amplitude of the first power supply is smaller than the amplitude of the second power supply. The control terminal of the power selection module is connected to the main control module, and receives instructions from the main control module to select a power supply for the valve. The output terminal of the power selection module is connected to the power supply terminal of the valve, and is used to provide power to the valve.

[0038] When the valve needs to be opened, the main control module sends a control instruction to the power selection module, and the power selection module selects the second power supply to power the valve. Since the second power supply has a larger amplitude, it can provide enough power to ensure that the valve can be opened reliably.

[0039] The opening detection module is used to detect the opening of the valve and feed back the detected opening information to the main control module. The main control module determines whether the valve has reached the target opening based on this information. When the valve opening reaches the set value, it sends a command to the power selection module to switch the power supply of the valve from the second power supply to the first power supply.

[0040] After the valve reaches the set opening, the first power source continues to supply power to the valve to maintain the valve opening at the set state. Since the amplitude of the first power source is small, the power it provides is sufficient to maintain the valve opening, while reducing the power loss of the coil inside the valve, which helps to increase the service life of the valve.

[0041] The main control module communicates with the power selection module and the opening detection module to monitor the valve opening and power status in real time, and adjust the valve opening and power supply as needed.

[0042] From the above, it can be concluded that by introducing the first power supply and the second power supply, the high-amplitude second power supply can be used to provide sufficient power during the valve opening stage to ensure that the valve opens reliably and quickly, meeting the rapid response requirements of industrial automation. Secondly, after the valve reaches the set opening, the power supply is switched to the first power supply with a smaller amplitude through the intelligent switching of the power selection module. This not only effectively reduces power consumption and energy waste, but also reduces the power loss of the coil inside the valve, significantly extending the service life of the valve. In addition, the coordinated work of the main control module, the power selection module, and the opening detection module realizes real-time monitoring and intelligent adjustment of the valve opening and power supply status, improving the stability and reliability of the entire valve regulation.

[0043] like Figure 2 As shown, in one embodiment of the present disclosure, it also includes a temperature detection module and an alarm module; the temperature detection module is connected to the main control module, and the temperature detection module is used to detect the working temperature of the valve; the alarm module is connected to the main control module.

[0044] In this embodiment, the intelligent regulating valve is additionally provided with a temperature detection module and an alarm module.

[0045] The temperature detection module is connected to the main control module and is used to monitor the working temperature of the valve in real time. When the valve is working, the temperature detection module transmits the detected temperature information to the main control module in real time. The main control module makes a judgment based on the preset temperature threshold. If the working temperature of the valve exceeds the set upper limit, the alarm module is triggered. After receiving the instruction from the main control module, the alarm module will send an alarm signal to remind the operator to pay attention to the possible overheating risk of the valve.

[0046] By adding a temperature detection module and an alarm module, the intelligent control valve of this embodiment has an overheat protection function. It can detect temperature anomalies during valve operation in a timely manner and quickly notify the operator through the alarm module, thereby effectively preventing equipment damage or safety accidents caused by overheating. This not only improves the safety of the control valve, but also reduces maintenance costs.

[0047] like Figure 2 As shown, in one embodiment of the present disclosure, a wireless communication module is also included; the main control module is connected to the terminal through the wireless communication module.

[0048] In this embodiment, a wireless communication module is added to the intelligent regulating valve. This module enables the main control module to establish a communication connection with an external terminal (such as a smart phone, tablet computer, computer or a special monitoring system, etc.). Through the wireless communication module, the main control module can send key parameters such as valve opening information, temperature data, power supply status, etc. to the terminal in real time, and can also receive control instructions from the terminal, such as setting the valve opening, modifying working parameters, etc. This communication method does not require physical line connection, which greatly increases the flexibility and scalability of the system.

[0049] In this embodiment, by introducing the wireless communication module, the remote monitoring and control capabilities of the intelligent regulating valve are significantly improved. In this embodiment, the operating status of the valve can be viewed in real time through any terminal connected to the network, and key information such as the valve opening and temperature can be understood, so as to promptly discover and deal with possible problems. At the same time, in this embodiment, the opening and closing of the valve can also be remotely controlled through the terminal, and the working parameters can be adjusted to achieve more flexible and convenient operation. This not only improves work efficiency, but also reduces maintenance costs.

[0050] like Figure 3 As shown, in one embodiment of the present disclosure, a power module is also included; the power module includes a resistor R7, a voltage regulator tube D1, an operational amplifier U1, a resistor R6, a resistor R5, a switch tube Q1 and a variable resistor RP3; a first end of the resistor R7 is connected to the VCC power supply, a second end of the resistor R7 is connected to the cathode of the voltage regulator tube D1, an anode of the voltage regulator tube D1 is grounded, a cathode of the voltage regulator tube D1 is connected to the non-inverting input terminal of the operational amplifier U1, and an inverting input terminal of the operational amplifier U1 is grounded through the resistor R5; a first end of the variable resistor RP3 is connected to the VCC power supply, a second end of the variable resistor RP3 is connected to the first end of the switch tube Q1, a second end of the switch tube Q1 is grounded, a first end of the switch tube Q1 is connected to the inverting input terminal of the operational amplifier U1, an output terminal of the operational amplifier U1 is connected to the inverting input terminal of the operational amplifier U1 through the resistor R6, and an output terminal of the operational amplifier U1 is used to output a first power supply.

[0051] In this embodiment, the power module is used to generate and stabilize the first power supply. First, the VCC power supply provides voltage to the voltage regulator D1 through the resistor R7. D1 acts as a voltage reference to ensure that the in-phase input terminal of the operational amplifier U1 has a stable reference voltage. The inverting input terminal of the operational amplifier U1 serves as an adjustment terminal, and the operational amplifier U1 constitutes an amplifier circuit to amplify the input voltage.

[0052] The voltage output by the operational amplifier U1 is used to maintain the valve opening unchanged. The voltage output by the operational amplifier U1 is fed back to the control end of the switch tube Q1. The switch tube Q1 in this embodiment can be an N-channel enhanced field effect tube. When the voltage output by the operational amplifier U1 increases, the voltage at the control end of the switch tube Q1 increases, and the current flowing through the first end of the switch tube Q1 increases. Therefore, the voltage at the inverting input end of the operational amplifier increases, resulting in a decrease in the voltage output by the operational amplifier U1. When the voltage output by the operational amplifier U1 decreases, the voltage at the control end of the switch tube Q1 decreases, and the current flowing through the first end of the switch tube Q1 decreases. Therefore, the voltage at the inverting input end of the operational amplifier decreases, resulting in a decrease in the voltage output by the operational amplifier U1. The output end of the operational amplifier U1 is the output of the power module, which provides a stable first power supply. The voltage value of this first power supply can be changed by adjusting the variable resistor RP3.

[0053] In this embodiment, the design of the power module provides a stable and reliable first power supply for the intelligent control valve. Through the feedback loop formed by the operational amplifier U1 and the switch tube, it can be ensured that the output voltage of the first power supply remains stable when the valve maintenance voltage changes or the ambient temperature changes. At the same time, by adjusting the variable resistor RP3, the voltage value of the first power supply can be easily changed to adapt to different working requirements. This not only improves the performance and reliability of the intelligent control valve, but also provides more flexible operation options.

[0054] like Figure 3 As shown, in one embodiment of the present disclosure, the power module also includes an inductor L2, a diode D3, a switch tube Q4 and a capacitor C4; the first end of the inductor L2 is connected to the output end of the operational amplifier U1, the second end of the inductor L2 is connected to the first end of the switch tube Q4, the second end of the switch tube Q4 is grounded, and the control end of the switch tube Q4 is connected to the main control module; the first end of the switch tube Q4 is connected to the anode of the diode D3, the cathode of the diode D3 is grounded through the capacitor C4, and the cathode of the diode D3 is used to output the second power supply.

[0055] In this embodiment, the inductor L2, the diode D3, the switch tube Q4 and the capacitor C4 form a boost circuit for raising the voltage output by the operational amplifier U1, and the boosted voltage is used to quickly open the valve.

[0056] The working principle of the boost circuit is based on the energy storage characteristics of the inductor L2 and the filtering characteristics of the capacitor C4. When the valve is opened, the main control module sends a PWM control signal to the control end of the switch tube Q4. When the PWM control signal is high, the switch tube Q4 is in the on state, and the current flows through the loop of the inductor L2 and the switch tube Q4, and the inductor L2 begins to store energy. At this time, the diode D3 is reversely cut off, and the capacitor C4 maintains the previous charging state. When the PWM control signal becomes low, the switch tube Q4 is turned off, and the current in the inductor L2 cannot disappear immediately. It will try to maintain the current direction unchanged, generating a reverse electromotive force. This electromotive force causes the voltage at the second end of the inductor L2 (i.e., the first end of the switch tube Q4) to rise instantly, exceeding the output voltage of the op amp U1. The diode D3 is turned on at this high voltage, allowing the current in the inductor L2 to continue to flow and charge the capacitor C4 through the diode D3, so the voltage across the capacitor C4 (i.e., the second power supply) increases. As time goes by, capacitor C4 will gradually become fully charged, and the voltage across it will stabilize at a higher value, which is higher than the output voltage of op amp U1, thus achieving a boost function.

[0057] In this embodiment, the design of the boost circuit provides a higher power supply voltage for the intelligent control valve, so that the valve can work normally when a higher voltage is required. Through the precise control of the switch tube Q4 by the main control module, the output voltage of the boost circuit can be adjusted, thereby meeting the power supply requirements of the intelligent control valve under different working conditions.

[0058] like Figure 3 As shown, in one embodiment of the present disclosure, the power module further includes a resistor R3; a first end of the resistor R3 is connected to a first end of the switch tube Q1, and a second end of the resistor R3 is connected to a control end of the switch tube Q1.

[0059] In practical applications, the first end of the switch tube Q1 may generate distortion during operation, which affects the voltage regulation performance. Therefore, in this embodiment, a resistor R3 is added between the control end of the switch tube Q1 and the first end of the switch tube Q1 to form a local feedback, thereby achieving the purpose of reducing distortion and improving the overall stability of the circuit.

[0060] like Figure 3 As shown, in one embodiment of the present disclosure, the power selection module includes a switch tube Q2 and a relay K2; the control end of the switch tube Q2 is connected to the main control module, the first end of the switch tube Q2 is connected to the first input end of the relay K2, the second input end of the relay K2 is connected to the VCC power supply, and the second end of the switch tube Q2 is grounded; the normally open end of the relay K2 serves as the first input end of the power selection module, the normally closed end of the relay K2 serves as the second input end of the power selection module, the common end of the relay K2 is connected to the first power supply end of the valve, and the second power supply end of the valve is grounded.

[0061] In this embodiment, when the valve needs to be opened, the main control module sends a high-level signal to the control end of the switch tube Q2, the switch tube Q2 is turned on, and the relay K2 is energized and attracted. At this time, the common end of the relay K2 is connected to the normally open end of the relay K2, that is, the power supply end of the valve is connected to the second power supply. After the power is turned on, the valve can be opened quickly. When the opening of the valve reaches the specified opening, the main control module sends a low-level signal to the control end of the switch tube Q2, the switch tube Q2 is turned off, the relay K2 loses power, and the common end of the relay K2 is connected to the normally closed end of the relay K2. At this time, the valve is connected to the first power supply to maintain the current opening.

[0062] In this embodiment, the power selection module allows the intelligent regulating valve to switch between different power supplies as needed, thereby improving the flexibility and adaptability of this embodiment. By switching the relay K2, it can be ensured that the power supply to the valve will not be interrupted during the power switching process, thereby improving the stability of this embodiment.

[0063] like Figure 4 As shown, in one embodiment of the present disclosure, the opening detection module includes a rheostat RP2, a resistor R14, an operational amplifier U2, a Hall sensor U3, an operational amplifier U2, a resistor R15, a transistor Q5 and a resistor R12; a first end of the rheostat RP2 is connected to the VCC power supply, a second end of the rheostat RP2 is grounded through the resistor R14, a sliding end of the rheostat RP1 is connected to the in-phase input end of the operational amplifier U2, an inverting input end of the operational amplifier U2 is connected to the output end of the Hall sensor U3, a power supply end of the Hall sensor U3 is connected to the VCC power supply, a ground end of the Hall sensor U3 is grounded, an output end of the operational amplifier U2 is connected to the inverting input end of the operational amplifier U2 through the resistor R15, an output end of the operational amplifier U2 is connected to the base of the transistor Q5, a collector of the transistor Q5 is connected to the VCC power supply, an emitter of the transistor Q5 is grounded through the resistor R12, and an emitter of the transistor Q5 is connected to the main control module.

[0064] In this embodiment, the Hall sensor U3 is used to detect the opening of the valve. The Hall sensor U3 is used to convert the opening of the valve into a corresponding electrical signal output. In this embodiment, the larger the opening of the valve, the smaller the current output by the Hall sensor U3, and the smaller the opening of the valve, the larger the current output by the Hall sensor U3. The current output by the Hall sensor U3 is converted into a voltage signal through the resistor R13 and sent to the inverting input terminal of the operational amplifier U2. The variable resistor RP2 provides a reference voltage for the in-phase input terminal of the operational amplifier U2. The operational amplifier U2 constitutes an amplification circuit. Since the current output by the Hall sensor U3 is small, the main control module cannot directly identify it. Therefore, it needs to be amplified by the operational amplifier U2. The amplified voltage is added to the base of the transistor Q5. The larger the opening of the valve, the smaller the current applied to the transistor Q5 will be, and the smaller the current flowing through the resistor R12 will be, so the voltage on the resistor R12 will be smaller, and vice versa. The voltage on the resistor R12 will be larger, and the main control module can judge the opening of the valve through the voltage on the resistor R12.

[0065] In this embodiment, the opening change of the valve is monitored in real time by the Hall sensor U3, so that the movement state of the valve can be reflected in real time.

[0066] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
