Description

Technical Field

[0001] The utility model relates to the technical field of valve control, and particularly to an electric valve control device. Background Art

[0002] In the fields of modern industry and automation control, electric valve control devices are crucial equipment for precisely controlling the flow of fluids, such as liquids or gases, and are widely used in various industrial processes, including chemical industry, pharmaceuticals, food processing, water treatment, etc. The design and development of electric valve control devices aim to achieve remote control, precise positioning, and reliable operation of valves. However, existing valve control systems have unsolvable problems in some specific scenarios, especially when the valve needs to operate as the device rotates or moves.

[0003] In existing systems, cables or wires usually connect the valve and the control system through fixed joints or rails. When the triggering device needs to rotate or move, the cables may be twisted, stretched, or broken, resulting in unstable connections or unreliable transmission of electricity or signals. Especially in the case of high-frequency or long-term operation, existing cable connections may cause contact problems or breaks due to frequent movement, which will affect the real-time control and response ability of the valve. For example, in a control system on an automated assembly line, in this device, the triggering component is installed on the moving arm or robotic arm of the device, and these arms or robotic arms are responsible for moving on the assembly line. The electric valve control device is used to control the opening action of the valve to achieve various assembly operations. However, the triggering component is triggered by the rotation of the robotic arm. For example, when grasping or releasing parts at specific positions, the valve control device is triggered to ensure the correct execution of operations. Due to the limitations of existing cable connections, this rotation will cause the cables to be twisted or stretched, thus affecting the transmission of electrical signals and power supply in the control device, and further unable to stably control the opening and closing of the valve.

[0004] Therefore, designing an electric valve control device that can solve the above problems and work stably in a rotating or moving environment has become an important problem in the current technical field. Summary of the Utility Model

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection, a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] In the present utility model, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them.

[0031] Refer to Figures 1-3, an electric valve control device in an embodiment of the present utility model includes: a housing 1, with a switch assembly disposed inside the housing 1; a valve body 3, which is disposed on the outer wall of the housing 1, and one end of the valve body 3 is connected to the switch assembly inside the housing 1, and the opening and closing of the valve are realized through the drive of the switch assembly; a conductive slip ring 4, including an insulating base 41, a rolling bearing 42 and a conductive shaft 43, the insulating base 41 is disposed at one end of the outer wall of the housing 1 and away from the valve body 3, one end of the conductive shaft 43 penetrates the inside of the insulating base 41 and is connected to an electric cylinder 46, and the other end is connected to the rolling bearing 42, and a trigger member 45 is sleeved on the outer wall of the rolling bearing 42; a trigger shaft 5, one end of the trigger shaft 5 is connected to the switch assembly, and the other end penetrates the housing 1 and the insulating base 41 and is disposed corresponding to the electric cylinder 46, wherein the output shaft of the electric cylinder 46 can axially move along the direction of the trigger shaft 5 to contact or disengage from the trigger shaft 5.

[0032] In this embodiment, stable and reliable control of the valve is achieved in a rotating or moving environment, solving the problem that the cables of existing electric valve control devices are prone to twisting, stretching or breaking during dynamic operation, and greatly improving the durability and reliability of the system. Specifically, through the design of the conductive slip ring 4, stable transmission of power and signals is achieved during the rotation or movement of the valve control device. The insulating base 41 serves as the basic support of the conductive slip ring 4, ensuring electrical isolation between the conductive shaft 43 and the housing 1 and preventing the risk of short circuit or leakage. The rolling bearing 42 enables the conductive shaft 43 to rotate smoothly with the trigger member 45 while maintaining stable contact with the trigger member 45, effectively solving the problem that traditional cables are prone to twisting, stretching or breaking during rotation. The low-friction characteristic of the rolling bearing 42 also reduces energy loss and improves the operating efficiency of the entire device. The combination of the rolling bearing 42 and the conductive shaft 43 realizes an efficient electrical connection between the rotating part and the stationary part, not only ensuring the stability of power and signal transmission, but also avoiding physical wear caused by mechanical movement and extending the service life of the equipment. One end of the trigger shaft 5 is connected to the switch assembly, and the other end corresponds to the output shaft of the electric cylinder 46. When the electric cylinder 46 receives a control signal, its output shaft will axially move along the direction of the trigger shaft 5 to precisely contact or disengage from the trigger shaft 5, thereby realizing the control of the opening and closing of the valve. This design not only simplifies the control logic, but also greatly improves the control accuracy and response speed. In summary, the electric valve control device of the present utility model, when dealing with complex and changeable industrial environments, not only solves the instability and vulnerability problems of traditional cable connections during rotation or movement, but also further improves the overall performance and safety of the system.

[0033] In practical applications, the electric valve control device of the present utility model can be widely used in various scenarios where the valve needs to be operated as the equipment rotates or moves. For example, on an automated assembly line, the device can be installed on a moving arm or a robotic arm to precisely control the opening and closing of the valve as the robotic arm rotates and moves, realizing assembly operations such as part grasping and releasing. Due to the design of the conductive slip ring 4 and the trigger shaft 5, even in the case of high-frequency or long-term operation, stable transmission of power and signals can be ensured, avoiding problems such as unstable or easily damaged cable connections.

[0034] It should be noted that the switch assembly in this embodiment is electrically connected to the valve body 3. For example, the rotation or lifting of the valve body 3 can be directly driven by an electromagnetic driver or a motor to achieve the opening and closing of the valve, or directly connected to the internal circuit board through a wire to receive and analyze instructions from an external controller.

[0035] In one embodiment, the switch assembly includes two first fixing parts 23 and a second fixing part 24. The second fixing part 24 is arranged between the two first fixing parts 23. The trigger shaft 5 passes through one of the fixing parts and the second fixing part 24 and is connected to the other fixing part.

[0036] In this embodiment, the switch assembly is composed of two first fixing parts 23 and a second fixing part 24 located between them. Such a layout not only enhances the overall stability of the switch assembly but also improves its durability under complex working conditions. The trigger shaft 5 passes through one of the first fixing parts 23 and the second fixing part 24 and is tightly connected to the other first fixing part 23, making the movement of the trigger shaft 5 smoother, reducing the deviation caused by vibration or impact, and thus ensuring the accuracy of valve opening and closing.

[0037] In one embodiment, the switch assembly further includes a plurality of first contacts 21 and second contacts 22. The plurality of first contacts 21 are arranged on the side of the first fixing part 23 facing the second fixing part 24, and the second contacts 22 are arranged on the two sides of the second fixing part 24 facing the first fixing part 23 to form an electrical contact pair.

[0038] In this embodiment, a plurality of first contacts 21 and second contacts 22 are provided between the first fixing portion 23 and the second fixing portion 24, forming a plurality of electrical contact pairs, increasing the contact area of the contacts, improving the stability of power and signal transmission, and reducing the risk of single-point failure through redundant design. Even if some contacts fail due to wear or contamination, other contacts can still maintain normal operation, ensuring the stable operation of the valve control device. Specifically, when the electric cylinder 46 receives a control signal and drives its output shaft to move axially, the trigger shaft 5 will move accordingly, causing a change in the electrical connection state between the first contact 21 and the second contact 22. This change is converted into an electrical signal, which in turn controls the opening and closing of the valve body 3. Since multiple contacts participate in the work simultaneously, even if a certain contact has poor contact or fails, it will not have a serious impact on the entire system, thereby improving the fault tolerance and reliability of the system. In addition, during long-term use, the contacts may have poor contact due to wear, contamination, oxidation, or other reasons. At this time, simply disassembling and replacing the damaged contacts can restore the normal operation of the system, without the need for major repairs or replacement of the entire switch assembly, greatly reducing the maintenance cost and downtime. It should be noted that in order to ensure good contact of the contacts and reduce wear, the surface of the contacts can also be specially treated. For example, materials with excellent electrical conductivity and wear resistance such as gold plating and silver plating can be used for surface treatment; or a composite contact structure can be adopted, combining contacts of different materials together to utilize their respective advantages to improve the comprehensive performance of the contacts.

[0039] In one embodiment, it further includes a first elastic member 61. One end of a plurality of the first elastic members 61 is disposed on both sides of the second fixing portion 24, and the other end is connected to the second contact 22, for keeping the second contact 22 in a stable electrical isolation state from the first contact 21 when the trigger shaft 5 is not under the pressure of the output shaft of the electric cylinder 46.

[0040] In this embodiment, the first elastic member 61 is disposed on both sides of the second fixing portion 24 and is respectively connected to the second contact 22. When the trigger shaft 5 is not subjected to the pressure of the output shaft of the electric cylinder 46, the first elastic member 61 will utilize its elastic force to keep the second contact 22 and the first contact 21 in a stable electrical isolation state. This design effectively prevents unintended electrical contact caused by vibration, shock or misoperation, and further reduces the risk of short circuit or malfunction. During the actual working process, when the electric cylinder 46 receives a control signal and drives its output shaft to move towards the trigger shaft 5, the output shaft will apply a certain pressure to the trigger shaft 5, thereby overcoming the elastic force of the first elastic member 61, causing the second contact 22 and the first contact 21 to be in close contact to form an electrical path. At this time, power and signals are stably transmitted, and the valve body 3 performs corresponding opening and closing actions according to the received instructions. When the output shaft of the electric cylinder 46 moves in the reverse direction or stops working, the first elastic member 61 will quickly return to its original state, isolating the second contact 22 and the first contact 21 again to ensure the safety and stability of the system. In addition, the design of the first elastic member 61 also has a certain buffering effect. At the moment when the output shaft of the electric cylinder 46 contacts the trigger shaft 5, certain impact or vibration may be generated. The first elastic member 61 can absorb this part of the energy, reduce the impact on the internal structure of the switch assembly, thereby extending the service life of the device. At the same time, this buffering effect also helps to maintain the stability of the contact, avoiding poor contact or damage caused by the impact during the contact moment.

[0041] In one embodiment, a second elastic member 62 is further included. The second elastic member 62 is disposed directly between the first fixing portion 23 and the second fixing portion 24 and sleeved on the trigger shaft 5 for providing a pre-tightening force when the trigger shaft 5 is not subjected to the pressure of the output shaft of the electric cylinder 46.

[0042] In this embodiment, the second elastic member 62 is disposed between the first fixing portion 23 and the second fixing portion 24 and tightly sleeved on the trigger shaft 5. When the trigger shaft 5 is not subjected to the pressure of the output shaft of the electric cylinder 46, a moderate pre-tightening force is provided for the trigger shaft 5. This pre-tightening force not only ensures the stability of the trigger shaft 5 in the static state, reduces the small displacement caused by vibration or external factors, but also optimizes the response speed of the trigger shaft 5 when receiving the pressure of the output shaft of the electric cylinder 46. Specifically, when the output shaft of the electric cylinder 46 starts to apply pressure to the trigger shaft 5, since the second elastic member 62 has provided a certain pre-tightening force for the trigger shaft 5, the trigger shaft 5 can move to the position in contact with the first contact 21 more quickly and smoothly. This process reduces the delay or deviation caused by the unstable initial position of the trigger shaft 5, thereby improving the accuracy and response speed of the valve opening and closing operation. In addition, the presence of the second elastic member 62 also plays a certain role in shock absorption and buffering. During the process of the output shaft of the electric cylinder 46 contacting the trigger shaft 5 and transmitting force, certain impact and vibration may be generated. The second elastic member 62 can absorb this impact energy and convert it into its own elastic potential energy for storage, and then slow down the transmission of vibration during the release process, protecting the precision structure inside the switch assembly from damage.

[0043] In one embodiment, a plurality of rolling cylinders are provided inside the rolling bearing 42. The side surfaces of the rolling cylinders are in close contact with the inner wall of the rolling bearing 42, and one end of the rolling cylinder is connected to the central shaft inside the rolling bearing 42.

[0044] In this embodiment, a plurality of rolling cylinders are provided inside the rolling bearing 42. The cylinders are in close contact with the inner wall of the bearing with their side surfaces, realizing low-friction and high-efficiency rotational motion. One end of the cylinders is connected to the central shaft inside the bearing, forming a stable and efficient transmission system. The close contact between the rolling cylinders and the inner wall effectively reduces the friction loss during rotation, enabling the switch assembly to still maintain a highly efficient and stable operating state under high-frequency and long-time operations, extending the service life of the equipment, and significantly reducing the performance degradation and safety hazards caused by heat generation due to friction. Secondly, the connection between the rolling cylinders and the central shaft ensures the accurate transmission of the driving force. During the process of the output shaft of the electric cylinder 46 driving the trigger shaft 5 to move, through the precise conduction of the rolling bearing 42, the movement trajectory of the trigger shaft 5 is smoother and more precise, thereby further improving the accuracy and reliability of valve opening and closing. Even under complex and changeable working conditions, the accurate control of the valve can be ensured.

[0045] In one embodiment, the valve body 3 includes a valve flap and a seal. The valve flap is disposed in the internal passage of the valve body 3, and the seal is disposed between the valve flap and the inner wall of the valve body 3.

[0046] In this embodiment, the valve flap is arranged in the internal channel and can flexibly open or close the channel according to the control signal to achieve the on-off regulation of the fluid. To ensure that the valve flap can completely block the fluid in the closed state and can flow smoothly when opened, a seal is configured between the valve flap and the inner wall of the valve body 3. The seal can be made of materials with good wear resistance, corrosion resistance, and elasticity, such as rubber, fluororubber, or polytetrafluoroethylene, etc., and closely adheres to the contact surface between the valve flap and the inner wall of the valve body 3, forming a reliable sealing barrier to effectively prevent the leakage of fluid in the closed state. In practical applications, the valve body 3 may also need to face various complex working conditions, such as high temperature, high pressure, strong corrosion, etc. To address these challenges, the valve body 3 can also be specially treated or additional protection devices can be configured. For example, an insulation layer or a cooling device can be added to the outer wall of the valve body 3 to control the temperature; an anti-corrosion coating can be set around the seal or a double-seal structure can be adopted to improve the sealing performance; a pressure sensor or a temperature sensor can be installed at key positions to monitor the changes in the working conditions in real time, etc.

[0047] In one embodiment, the valve body 3 further includes a drive arm. One end of the drive arm is fixedly connected to the valve flap, and the other end is connected to the switch assembly in the housing 1, and is used to push the drive arm through the switch assembly, and then drive the valve flap to move in the internal channel of the valve body 3.

[0048] In this embodiment, one end of the drive arm is connected to the valve flap, ensuring the stability and reliability of the valve flap during movement. The other end is connected to the switch assembly in the housing 1, realizing the precise conversion from electrical signal to mechanical movement. When the switch assembly receives the control signal and drives the trigger shaft 5 to move, through a series of precise mechanical linkage devices, the power is finally transmitted to the drive arm. After receiving this power, the drive arm will respond quickly and smoothly, pushing the connected valve flap to perform linear or rotational movement in the internal channel of the valve body 3. In addition, the design of the drive arm also fully considers space utilization and dynamic balance. In the limited space inside the housing 1, the drive arm realizes an efficient transmission path and a compact installation method by optimizing the layout and reducing unnecessary structural parts. At the same time, the drive arm maintains dynamic balance during movement, reducing the impact and wear on the internal structure of the valve body 3 caused by vibration and shaking, and further improving the overall performance and service life of the valve body 3. In practical applications, the drive arm may also need to be customized or optimized according to specific working conditions. For example, in an environment with high temperature, high pressure, or strong corrosion, materials with high temperature, high pressure, and corrosion resistance need to be selected to manufacture the drive arm; in occasions where the position of the valve flap needs to be precisely controlled, high-precision transmission mechanisms and adjustment devices need to be adopted to ensure the movement accuracy and stability of the drive arm.

[0049] In one embodiment, the switch assembly further includes a bottom plate and a plurality of fixing members. Both the first fixing portion 23 and the second fixing portion 24 are disposed on the bottom plate, and the plurality of fixing members penetrate through the first fixing portion 23 and are fixedly connected to the bottom plate.

[0050] In this embodiment, the bottom plate is the basic support structure of the switch assembly. The first fixing portion 23 and the second fixing portion 24 are firmly installed on the bottom plate, ensuring the accuracy of their relative positions. The plurality of fixing members vertically penetrate the first fixing portion 23 to connect it to the bottom plate, forming a stable overall structure. This connection method not only improves the overall stability of the switch assembly but also enables the components to work together when subjected to external forces, jointly resisting external interference, and ensuring the accuracy and reliability of valve control.

[0051] In one embodiment, the electrical connection between the conductive shaft 43 and the electric cylinder 46 is achieved through a connector.

[0052] In this embodiment, a connector is used for the electrical connection between the conductive shaft 43 and the electric cylinder 46. This connector is designed with a reliable contact mechanism and a sealing structure to ensure stable electrical signal transmission even in harsh environments. For example, the connector uses gold-plated or silver-plated contact terminals inside. These materials not only have excellent electrical conductivity but also can effectively resist oxidation and corrosion, extending the service life. At the same time, the connector housing is made of high-strength and wear-resistant materials such as stainless steel or aluminum alloy, and is equipped with waterproof and dustproof sealing gaskets to ensure normal operation in humid and dusty industrial environments without being interfered by external factors. Or through a precise male-female head docking design to ensure the accuracy and reliability of the electrical connection between the conductive shaft 43 and the electric cylinder 46. During the connection process, clear indication marks and anti-misoperation mechanisms can also be set to effectively avoid connection errors or damages caused by misoperation. In addition, the insertion and extraction force of the connector is appropriate, which not only ensures the firmness of the connection but also facilitates subsequent maintenance and replacement work.

[0053] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
