Description

Technical Field

[0001] The invention relates to the field of electromagnetic control valves, and in particular to an electromagnetic automatic control valve device. Background Art

[0002] The electromagnetic automatic control valve is an automated device that uses electromagnetic force to control the opening and closing of valves. Such devices are widely used in industrial process control, fluid transmission systems, HVAC systems, automotive engineering, and other fields that require precise control of fluid flow. The core lies in the application of electromagnetic force. When current passes through the electromagnetic coil, a magnetic field is generated. This magnetic field attracts or repels a piston or iron core made of magnetic material, thereby driving the valve core inside the valve to move.

[0003] In the prior art, although electromagnetic automatic control valves can respond quickly, they usually only have simple opening and closing functions, which means that once the valve is activated, it will be fully open and will not close until it receives a closing command, and it is impossible to adjust the opening according to actual needs. In scenarios where precise control of the valve position is required, such devices may not meet the requirements.

[0004] In summary, how to solve the problem that the electromagnetic automatic control valve in the prior art only has the functions of opening and closing, resulting in the inability to adjust the opening according to actual needs has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose an electromagnetic automatic control valve device that can accurately control the valve position. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an electromagnetic automatic control valve device, which can achieve more precise and accurate operation and meet the control requirements of different valve opening degrees by accurately controlling the movement stroke of the moving iron core through the induction layer.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an electromagnetic automatic control valve device includes a base, the base has an input port and an output port that are interconnected; a valve component is provided inside the base for blocking the interconnection between the input port and the output port of the base.

[0007] The valve assembly includes a control system, an electromagnetic coil, a fixed iron core, a moving iron core and a spring. The electromagnetic coil is sleeved on the outside of the fixed iron core, and the control system is used to control the operation of the electromagnetic coil; the spring is fixedly connected to the bottom of the fixed iron core, and the end of the spring away from the fixed iron core is fixedly connected to the top of the moving iron core, and the moving iron core and the electromagnetic coil are vertically slidably matched; the end of the moving iron core away from the spring extends to the inside of the base and is fixedly connected to a baffle, and the bottom of the baffle is in contact with the connecting point between the input port and the output port of the base.

[0008] A rubber piston is fixedly connected to the top of the baffle, and the rubber piston is vertically slidably matched with the inner wall of the base; a limit assembly for limiting the movement range of the moving iron core is provided above the rubber piston; the limit assembly includes an induction layer controlled by electric energy, and the control system is used to control the input size of the current to the induction layer, and the bottom of the induction layer is fixedly connected to the top of the rubber piston.

[0009] The technical principles of the above scheme are as follows:

[0010] When the electromagnetic coil is energized, a magnetic field will be generated around it. The fixed iron core, as part of the magnetic field, provides a fixed point for the movement of the moving iron core. The moving iron core is connected to the fixed iron core through a spring. When the electromagnetic coil is energized to generate a magnetic field, the moving iron core will be affected by the magnetic force so that the moving iron core and the fixed iron core are attracted to each other. When attracted, the moving iron core will overcome the elastic force of the spring and move toward the direction of the fixed iron core. During the movement of the moving iron core, the baffle will move together. When the baffle is separated from the connection between the input port and the output port of the base, the input port and the output port of the base are connected. In this movement process, the movement stroke of the moving iron core is limited by the difference in the input current of the induction layer. This induction layer material has properties such as electrostrain, which can convert electrical energy into mechanical energy to achieve changes in its shape and size. When the electromagnetic coil is de-energized, the elastic force of the spring will reset the moving iron core, so that the baffle blocks the connection between the base, thereby achieving the closure of the input port and the output port of the base.

[0011] The above scheme has the following beneficial effects:

[0012] 1. This scheme uses the induction layer to precisely control the travel of the moving iron core. The induction layer material has properties such as electrostrain, that is, it can change its shape and size by changing the input current, and can control the travel of the moving iron core, thereby precisely controlling the degree of opening of the valve. The valve opening can be precisely controlled as needed to achieve precise regulation of the fluid flow. The bottom of the induction layer is fixedly connected to the top of the rubber piston; when the electromagnetic coil is energized, the magnetic field generated can act more effectively on the induction layer, thereby improving the response speed and sensitivity of the electromagnetic automatic control valve.

[0013] 2. This solution uses mechanical structures such as fixed iron core, moving iron core, spring and electromagnetic coil to ensure that the valve can be reliably reset when the power is off. After the electromagnetic coil is energized, the magnetic field is immediately generated, and the moving iron core moves quickly to drive the baffle to open the valve. It has a fast response speed and high opening and closing efficiency. The design of the vertical sliding cooperation between the moving iron core and the electromagnetic coil enables the moving iron core to move smoothly when it is acted upon by the electromagnetic force, without affecting the control accuracy due to looseness or offset of the structure.

[0014] 3. This solution uses rubber piston as a sealing barrier material, which has good sealing properties. In the electromagnetic automatic control valve device, the rubber piston can fit the valve seat tightly, effectively preventing medium leakage and ensuring the stability and safety of the system. In addition, the rubber piston can effectively reduce the gap changes caused by factors such as vibration or pressure fluctuations, thereby enhancing the sealing performance of the entire device.

[0015] Furthermore, the sensing layer is made of one or more materials selected from lead zirconate titanate, polyvinylidene fluoride, ion gel and dielectric elastomer.

[0016] Beneficial effects: The sensing layer uses electrostrain materials, which can achieve precise control of the valve opening, thereby accurately adjusting the fluid flow. These materials have fast response characteristics, allowing the valve to be adjusted quickly and improving the response speed of the device. These materials have good electrical or physical properties, and can accurately sense the opening and closing state of the valve or changes in parameters such as pressure and temperature of the fluid, thereby achieving more precise control.

[0017] Furthermore, the baffle is in an inverted convex shape, a pressure relief pipe is fixedly connected to the inner bottom wall of the base, and a pressure relief port is opened inside the pressure relief pipe; both ends of the pressure relief port are respectively connected to the output port and the input port of the base, and the bottom of the baffle is in contact with the top of the pressure relief port.

[0018] Beneficial effect: The inverted convex baffle allows the medium to contact the output port first through the pressure relief port at the input port during operation, thereby generating pressure relief, which can enable the subsequent baffle to be pushed open smoothly during the opening process, thereby connecting the two sides. Conversely, the pressure relief port can be blocked first by the inverted convex baffle, so that the subsequent medium follows the baffle to close the input port and the output port, thereby improving the operating efficiency of the device.

[0019] Furthermore, a top cover is fixedly connected to the top of the base, the moving iron core passes through the top cover and vertically slides with the top cover; the top of the induction layer is fixedly connected to the bottom of the top cover.

[0020] Beneficial effect: The chamber where the sensing layer is located is closed by the top cover, which can provide an additional sealing effect to prevent external pollutants from entering the control valve. It can also prevent internal fluid or gas leakage, ensure the normal operation and service life of the automatic control valve, and reduce maintenance costs and time.

[0021] Furthermore, a shell is provided on the outer side of the electromagnetic coil, and the bottom of the shell is fixedly connected to the top of the top cover.

[0022] Beneficial effect: The fixed connection between the outer shell and the top cover forms a closed space, which can effectively prevent external impurities such as dust and moisture from entering the control valve, thereby improving the protection level of the device.

[0023] Furthermore, the gap between the rubber piston and the electromagnetic coil forms a cavity, which is filled with a protective liquid. A channel is opened in the top cover, and the rubber piston and the cavity of the electromagnetic coil are connected up and down through the channel.

[0024] Beneficial effects: The protective fluid has a certain heat transfer effect. During the operation of the device, a certain amount of heat will be generated. The protective fluid can absorb and disperse this heat, help maintain the temperature stability of the environment around the electromagnetic coil and rubber piston, and prevent performance degradation or damage caused by overheating. The protective fluid can reduce the gap change and friction resistance between the rubber piston and the electromagnetic coil, making the electromagnetic automatic control valve respond to the control signal more quickly and accurately; this helps to improve the accuracy and response speed of the entire device and meet the control needs with higher precision requirements.

[0025] Furthermore, a temperature sensor and a pressure sensor are fixedly connected to the inner wall of the upper portion of the base, and the control system is used to receive signals from the temperature sensor and the pressure sensor.

[0026] Beneficial effect: Based on the precise data provided by the temperature sensor and the pressure sensor, the control system can more accurately determine the current operating status of the system and adjust the opening, flow rate and operating parameters of the device accordingly, thereby helping to improve the stability of the device operation.

[0027] Furthermore, a refrigeration system is fixedly connected to the outer wall of the upper portion of the base, and an output end of the refrigeration system is communicated with the interior of the cavity; and a control system is used to control the operation of the refrigeration system according to a signal from a temperature sensor.

[0028] Beneficial effects: In high temperature environments, the electronic components and mechanical parts inside the electromagnetic automatic control valve are easily damaged or their performance degraded due to overheating; the protective liquid inside the cavity is timely cooled by the refrigeration system, which can effectively prevent this from happening and improve the reliability and service life of the equipment.

[0029] Furthermore, a heating system is fixedly connected to the inner wall of the upper portion of the base, and the control system is used to control the operation of the heating system according to the signal of the temperature sensor.

[0030] Beneficial effect: Temperature has a certain influence on the response speed of the control valve. Too low temperature may cause the response speed of the electromagnetic coil and the moving iron core to decrease. Maintaining a suitable temperature through the heating system can further ensure that the control valve has the ability to respond quickly under low temperature conditions.

[0031] Furthermore, the control system includes the following modules:

[0032] An information acquisition module is used to collect real-time signals of the control valve, including current, voltage, temperature and pressure signals;

[0033] The information processing module is used to pre-process, filter and convert the collected real-time signals to extract control logic information, and analyze and calculate the control logic information through algorithms;

[0034] The logic execution module is used to select and adjust the opening degree and operating temperature of the control valve according to different application scenarios and requirements; and generate control instructions based on the control logic information to control the opening degree and operating time of the electrical components inside the control valve in real time;

[0035] The monitoring and early warning module is used to set the monitoring threshold according to the real-time signal, and trigger the alarm signal if the real-time signal is found to be out of the normal range.

[0036] Beneficial effects: Through the coordinated work of the entire control system, the electromagnetic automatic control valve device can maintain a stable operating state under complex and changeable working conditions. Through real-time monitoring, precise control and efficient early warning, the system failure rate and downtime are effectively reduced, and the stability and reliability of the system are improved. It can be selected and adjusted according to different application scenarios and needs to generate control instructions that meet the actual situation. Through the real-time control of the opening degree and running time of the device, the electromagnetic automatic control valve can be accurately controlled.

DETAILED DESCRIPTION

[0042] The following is further described in detail through specific implementation methods:

[0043] Embodiment 1:

[0044] As attached Figure 1 , Figure 2As shown: an electromagnetic automatic control valve device, including a base 1, the base 1 is provided with an input port and an output port that are interconnected; the outer side walls of the input port and the output port of the base 1 are both provided with threaded grooves, the design of the threaded grooves enables the device to be quickly assembled, and a valve component is provided inside the base 1 for blocking the input port and the output port of the base 1 from being connected to each other.

[0045] The valve assembly includes a control system, an electromagnetic coil 2, a fixed iron core 3, a moving iron core 4 and a spring 5. The electromagnetic coil 2 is sleeved on the outside of the fixed iron core 3, and the control system is used to control the operation of the electromagnetic coil 2; the spring 5 is bolted and fixedly connected to the bottom of the fixed iron core 3, and the end of the spring 5 away from the fixed iron core 3 is bolted and fixedly connected to the top of the moving iron core 4, and the moving iron core 4 is vertically slidably matched with the electromagnetic coil 2; the end of the moving iron core 4 away from the spring 5 extends to the inside of the base 1 and is bolted and fixedly connected with a baffle 6, and the bottom of the baffle 6 is in contact with the connecting point between the input port and the output port of the base 1; a rubber piston 7 is fixedly bonded to the top of the baffle 6, and the rubber piston 7 is vertically slidably matched with the inner wall of the base 1; a limit assembly for limiting the movement range of the moving iron core 4 is provided above the rubber piston 7.

[0046] The limit assembly includes a sensing layer 8 controlled by electric energy, and the sensing layer 8 is made of one or more materials selected from lead zirconate titanate, polyvinylidene fluoride, ion gel and dielectric elastomer; in this embodiment, the sensing layer 8 is made of lead zirconate titanate. As a typical piezoelectric material, lead zirconate titanate has a high piezoelectric coefficient and can produce a significant electrical response when subjected to external force. The control system is used to control the input size of the current of the sensing layer 8, and the bottom of the sensing layer 8 is fixedly bonded to the top of the rubber piston 7. When lead zirconate titanate is used as the sensing layer 8 in the electromagnetic automatic control valve, the opening and closing state of the valve or the pressure change of the fluid can be accurately sensed, thereby achieving more precise control.

[0047] The specific implementation process is as follows: first, the control valve is threadedly installed at the position where the medium needs to be controlled to flow; when the electromagnetic coil 2 is energized, a magnetic field will be generated around it, and the fixed iron core 3, as a part of the magnetic field, provides a fixed point for the movement of the moving iron core 4. The moving iron core 4 is connected to the fixed iron core 3 through the spring 5. When the electromagnetic coil 2 is energized to generate a magnetic field, the moving iron core 4 will be affected by the magnetic force so that the moving iron core 4 and the fixed iron core 3 are attracted to each other. When attracted, the moving iron core 4 will overcome the elastic force of the spring 5 and move in the direction of the fixed iron core 3. During the movement of the moving iron core 4, the baffle 6 is driven to move together. When the baffle 6 is separated from the connection between the input port and the output port of the base 1, the input port and the output port of the base 1 are connected to each other.

[0048] by Figure 2For example, when the electromagnetic coil 2 is energized, the moving iron core 4 and the fixed iron core 3 are attracted to each other, so that the moving iron core 4 compresses the spring 5 to drive the baffle 6 to move upward. When the baffle 6 moves to the point where it is disconnected from the base 1, the input port and the output port of the base 1 are connected to each other. In this movement process, the movement stroke of the moving iron core 4 is limited by the different input currents of the induction layer 8. The material of the induction layer 8 has properties such as electrostrain, which can convert electrical energy into mechanical energy to achieve changes in its shape and size. According to the preset parameters, the induction layer 8 is adjusted to the corresponding size, thereby achieving precise control of the opening of the baffle 6. In this way, the stroke of the moving iron core 4 is controlled, thereby accurately controlling the opening degree of the valve. The valve opening can be accurately controlled as needed to achieve precise regulation of the fluid flow. The bottom of the induction layer 8 is fixedly connected to the top of the rubber piston 7; when the electromagnetic coil 2 is energized, the magnetic field generated can act more effectively on the induction layer 8, thereby improving the response speed and sensitivity of the electromagnetic automatic control valve.

[0049] When the electromagnetic coil 2 is powered off, the elastic force of the spring 5 will reset the moving iron core 4, so that the baffle 6 blocks the connection of the base 1, thereby closing the input and output ports of the base 1. By using mechanical structures such as the fixed iron core 3, the moving iron core 4, the spring 5 and the electromagnetic coil 2, the response speed is fast and the opening and closing efficiency is high. The design of the vertical sliding fit between the moving iron core 4 and the electromagnetic coil 2 enables the moving iron core 4 to move smoothly when subjected to the electromagnetic force, without affecting the control accuracy due to structural looseness or offset. The rubber piston 7 is used as a sealing barrier material, which has good sealing properties. In the electromagnetic automatic control valve device, the rubber piston 7 can fit tightly to the valve seat, effectively preventing medium leakage and ensuring the stability and safety of the system. In addition, the rubber piston 7 can effectively reduce the gap changes caused by factors such as vibration or pressure fluctuations, thereby enhancing the sealing performance of the entire device.

[0050] Embodiment 2:

[0051] As attached Figure 2 As shown, the difference from the above embodiment is that the baffle 6 is inverted convex, the inner bottom wall of the base 1 is fixedly connected with a pressure relief pipe 9 by bolts, and a pressure relief port is opened inside the pressure relief pipe 9; the two ends of the pressure relief port are respectively connected with the output port and the input port of the base 1, and the bottom of the baffle 6 is in contact with the top of the pressure relief port.

[0052] The specific implementation process is as follows: the inverted convex baffle 6 allows the medium to contact the output port first through the pressure relief port at the input port during operation of the device, thereby generating pressure relief, which can enable the subsequent baffle 6 to be pushed open smoothly during the opening process, thereby connecting the two sides. Conversely, the pressure relief port can be blocked first by the inverted convex baffle 6, so that the subsequent medium follows the baffle 6 to close the input port and the output port, thereby improving the operating efficiency of the device.

[0053] Embodiment 3:

[0054] As attached Figure 1 , Figure 2 As shown, the difference from the above embodiment is that the top of the base 1 is fixedly connected to the top cover 10 by bolts, the moving iron core 4 passes through the top cover 10 and vertically slides with the top cover 10; the top of the induction layer 8 is fixedly connected to the bottom of the top cover 10 by bolts.

[0055] The specific implementation process is as follows: the chamber where the sensing layer 8 is located is sealed by the top cover 10, which can provide an additional sealing effect to prevent external pollutants from entering the interior of the control valve, and also prevent internal fluid or gas leakage, thereby ensuring the normal operation and service life of the automatic control valve and reducing maintenance costs and time.

[0056] Embodiment 4:

[0057] As attached Figure 1 , Figure 2 As shown, the difference from the above embodiment is that a shell 11 is sleeved on the outer side of the electromagnetic coil 2, and the bottom of the shell 11 is fixedly connected to the top of the top cover 10 by bolts.

[0058] The specific implementation process is as follows: a closed space is formed between the shell 11 and the top cover 10, which can effectively prevent external impurities such as dust and moisture from entering the control valve, thereby improving the protection level and service life of the device.

[0059] Embodiment 5:

[0060] As attached Figure 2 As shown, the difference from the above embodiment is that the gap between the rubber piston 7 and the electromagnetic coil 2 constitutes a cavity, the cavity is filled with protective liquid, a channel is opened in the top cover 10, and the rubber piston 7 and the cavity of the electromagnetic coil 2 are connected up and down through the channel.

[0061] The specific implementation process is as follows: the protective liquid has a certain heat transfer effect. During the operation of the device, a certain amount of heat will be generated. The protective liquid can absorb and disperse this heat, help maintain the temperature stability of the environment around the electromagnetic coil 2 and the rubber piston 7, and prevent performance degradation or damage due to overheating. The protective liquid can reduce the gap change and friction resistance between the rubber piston 7 and the electromagnetic coil 2, making the electromagnetic automatic control valve respond to the control signal more quickly and accurately; this helps to improve the accuracy and response speed of the entire device and meet the control requirements with higher precision.

[0062] Embodiment 6:

[0063] As attached Figure 2As shown, the difference from the above embodiment is that a temperature sensor and a pressure sensor are fixedly connected with bolts on the upper inner wall of the base 1, and the control system is used to receive signals from the temperature sensor and the pressure sensor.

[0064] The specific implementation process is as follows: Based on the precise data provided by the temperature sensor and the pressure sensor, the control system can more accurately determine the current operating status of the system and adjust the opening, flow rate and operating parameters of the device accordingly, thereby helping to improve the stability of the device operation.

[0065] Embodiment 7:

[0066] As attached Figure 2 As shown, the difference from the above embodiment is that the upper outer wall of the base 1 is bolted and fixedly connected with a refrigeration system. In this embodiment, the refrigeration system uses a refrigerator 12; the output end of the refrigerator 12 is connected to the inside of the cavity; the control system is used to control the operation of the refrigerator 12 according to the signal of the temperature sensor.

[0067] The specific implementation process is as follows: Under high temperature environment, the electronic components and mechanical parts inside the electromagnetic automatic control valve are easily damaged or their performance degraded due to overheating; the protective liquid inside the cavity is cooled in time by the refrigerator 12, which can effectively prevent this situation from happening and improve the reliability and service life of the equipment.

[0068] Embodiment 8:

[0069] As attached Figure 2 As shown, the difference from the above embodiment is that the upper inner wall of the base 1 is fixedly connected with a heating system by bolts. In this embodiment, the heating system uses a heating plate 13, and the control system is used to control the operation of the heating plate 13 according to the signal of the temperature sensor.

[0070] The specific implementation process is as follows: temperature has a certain influence on the response speed of the control valve. Too low temperature may cause the response speed of the electromagnetic coil 2 and the moving iron core 4 to decrease. Maintaining the appropriate temperature of the inner wall of the device by the heating plate 13 can further ensure that the control valve has the ability to respond quickly under low temperature conditions.

[0071] Embodiment 9:

[0072] As attached Figure 3 As shown, the difference from the above embodiment is that the control system includes the following modules:

[0073] The information acquisition module is used to collect real-time signals of the control valve, including current, voltage, temperature and pressure signals.

[0074] The information processing module is used to preprocess, filter and convert the collected real-time signals to extract control logic information, and analyze and calculate the control logic information through algorithms.

[0075] The logic execution module is used to select and adjust the opening degree and operating temperature of the control valve according to different application scenarios and requirements; and generate control instructions based on the control logic information to control the opening degree and operating time of the electrical components inside the control valve in real time.

[0076] The monitoring and early warning module is used to set the monitoring threshold according to the real-time signal. If the real-time signal is found to be out of the normal range, an alarm signal is triggered; the alarm signals in this example include abnormal current, abnormal voltage, temperature overload and abnormal pressure when the control valve is in operation.

[0077] The specific implementation process is as follows: Through the coordinated work of the entire control system, the electromagnetic automatic control valve device can maintain a stable operating state under complex and changeable working conditions. Through real-time monitoring, precise control and efficient early warning, the system failure rate and downtime are effectively reduced, and the stability and reliability of the system are improved. It can be selected and adjusted according to different application scenarios and needs to generate control instructions that meet the actual situation. Through the real-time control of the opening degree and running time of the device, the electromagnetic automatic control valve can be accurately controlled; unnecessary energy waste is avoided. At the same time, the efficient fault warning mechanism also helps to reduce energy loss and increased maintenance costs due to equipment failure.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
