Description

Technical Field

[0001] This application relates to the technical field of valve control, and in particular to an intelligent valve controller. Background Technology

[0002] Valves are commonly used in water pipes, gas pipes, and other similar applications. They are control components used to control fluid flow during fluid transmission. The operation method is usually manual adjustment of the valve to control the fluid flow rate. Using a valve controller makes valve adjustment more convenient and saves the time of turning the valve.

[0003] Traditional valve controllers mostly rely on the operator's skill to manually adjust the valve opening and closing degree, judging and further fine-tuning by observing the fluid flow. Visual judgment and actual state will deviate, and the whole process may require multiple cycles to reach the target value. This is not only time-consuming and labor-intensive, but also causes momentary instability in fluid transmission during the adjustment process, affecting the normal operation of downstream equipment. Utility Model Content

[0004] In order to precisely adjust the angle and direction of valve rotation, this application provides an intelligent valve controller.

[0005] This application provides an intelligent valve controller, which adopts the following technical solution:

[0006] An intelligent valve controller includes a housing, an input shaft, an output shaft, a first transmission assembly, a main control board, a magnet, a second transmission assembly, and a display assembly. The input shaft is rotatable and has a manual control unit at one end; the output shaft is rotatable and has a valve connection unit at one end; the first transmission assembly drives the output shaft to rotate when the input shaft rotates; the main control board is connected to a power source and has an encoder chip electrically connected to it; the magnet is rotatable, and the encoder chip receives the magnet's rotation information and transmits it to the main control board; the second transmission assembly drives the magnet to rotate when the output shaft rotates; and the display assembly is electrically connected to the main control board to display valve status information based on the magnet's rotation information.

[0007] By adopting the above technical solution, the intelligent valve controller is connected and installed with the valve. Manually rotating the input shaft transmits power to the first transmission component, which in turn drives the output shaft. When the output shaft rotates, the valve connection point located on the output shaft rotates coaxially, achieving valve control. The use of encoder chips and magnet encoding technology improves the accuracy of angle detection. When the output shaft rotates, it drives the second transmission component, which in turn drives the magnet. The encoder chip can then sense the magnet's transmission information through the Hall effect, convert and calculate the information, and transmit it to the main control board, further achieving precise valve sensing. The main control board converts and calculates the magnet's transmission information, transforming it into valve transmission information, which is then displayed on the screen.

[0008] Optionally, the intelligent valve controller also includes a drive assembly and a third transmission assembly. The drive assembly is electrically connected to the main control board and can drive the input shaft to rotate by driving the third transmission assembly.

[0009] By adopting the above technical solution, the valve can be automatically controlled using a drive component. The drive component is electrically connected to the main control board, and the electric drive component drives the input shaft to rotate, which is more labor-saving and more precise in controlling the valve rotation state. A third transmission component is inserted between the drive component and the input shaft. When the drive component is electrically driven, it drives the third component to drive, and the third transmission component then drives the input shaft to rotate, making the automatic and manual input paths independent. When the drive component fails or there is a power outage, the valve can be manually controlled.

[0010] Optionally, a first mating gear is coaxially fixed on the input shaft, and a second mating gear is coaxially fixed on the output shaft. The first transmission assembly includes a first gear set, which rotates by meshing with the first mating gear and the second mating gear.

[0011] By adopting the above technical solution, when the input shaft rotates, the first mating gear rotates, and through meshing with the first gear set, it drives the second mating gear to rotate, causing the output shaft fixed to the second mating gear to rotate. Through the transmission method of gear meshing, the stability and accuracy of power transmission from the input shaft to the output shaft are ensured, errors in the transmission process are reduced, and the reliability of the control valve is improved.

[0012] Optionally, the second transmission assembly includes a transmission shaft rotatably disposed within the housing, a first transmission gear coaxially fixed to the transmission shaft, a third mating gear coaxially fixed to the output shaft, the first transmission gear and the third mating gear meshing with each other, and a magnet disposed on the transmission shaft.

[0013] By adopting the above technical solution, in the second transmission assembly, when the output shaft rotates, the output shaft meshes with the first transmission gear on the transmission shaft through the third mating gear, driving the transmission shaft and the magnet on it to rotate. This structure enables the rotation of the output shaft to be stably and accurately transmitted to the magnet, ensuring that the encoder chip can accurately receive the magnet rotation information, thereby improving the accuracy of valve status detection.

[0014] Optionally, a fourth mating gear is coaxially fixed on the input shaft, the drive assembly includes a drive shaft and a fifth mating gear coaxially fixed on the drive shaft, and the third transmission assembly includes a second gear set, which transmits power by meshing with the fourth and fifth mating gears.

[0015] By adopting the above technical solution, the fourth mating gear of the input shaft, the fifth mating gear of the drive assembly, and the second gear set of the third transmission assembly mesh and transmit power. When the drive assembly is in motion, it drives the fifth mating gear mounted on the drive assembly to rotate. The fifth mating gear meshes and rotates with the third transmission assembly, which in turn drives the fourth mating gear meshing with the third transmission assembly to rotate, thus achieving the effect of the drive assembly driving the input shaft. This design ensures the stability and accuracy of power transmission from the drive assembly to the input shaft, making the automatic drive of the input shaft more reliable and improving the accuracy of automatic control. By changing the torque through the second gear set, excessive rotational force is avoided to prevent machine overload and damage.

[0016] Optionally, the magnet and the encoder chip interact with each other using non-contact magnetic signals, and the magnet is provided with a plastic part that partially covers the outer surface of the magnet.

[0017] By adopting the above technical solution, a space is left between the magnet and the encoder chip to achieve non-contact magnetic signal interaction. Non-contact interaction avoids wear caused by mechanical contact and ensures stable magnetic signal transmission. The plastic part wrapped around the outer surface of the magnet can ensure that the signal interaction between the magnet and the encoder chip is not interfered with, while not affecting the normal transmission of magnetic signals.

[0018] Optionally, the housing is equipped with an operating component that is electrically connected to the main control board and used to input control commands.

[0019] By adopting the above technical solution, and by providing operators with operating components, operators can input control commands, which are then transmitted to the main control board. After interpreting the commands, the main control board will provide feedback on the corresponding information and operations based on the input commands. When the drive component transmission information is input, the drive component can be controlled to perform transmission. By providing a convenient control command input method, operators can directly operate the valve to achieve control.

[0020] Optionally, the intelligent valve controller also includes a gearbox, which includes a housing and a support plate. The gearbox is fixed inside the housing and is used to house the first transmission component, the second transmission component, and the third transmission component.

[0021] By adopting the above technical solutions, the gearbox can effectively protect each transmission component from the influence of external dust and impurities, further ensuring stability, and also making the internal structure compact and reducing the overall size of the structure.

[0022] Optionally, the manual control unit has an internal hexagonal screw hole for accommodating the insertion of a hexagonal wrench to manually drive the input shaft to rotate; the internal hexagonal screw hole is located on the surface of the housing.

[0023] By adopting the above technical solution, it is convenient for staff to manually drive the input shaft to rotate using a common hex wrench, simplifying the manual operation process and improving the convenience and adaptability of manual control.

[0024] Optionally, the valve connection part is provided with an octagonal valve hole for multi-angle valve adaptation, and the valve connection part is provided with a mounting hole.

[0025] By adopting the above technical solution, the compatibility between the valve connection and the valve is improved, enabling valve installation at multiple angles; the mounting holes facilitate stable installation of the controller, ensuring the stability of the connection and making the installation process more convenient.

[0026] In summary, this application includes at least one of the following beneficial effects:

[0027] 1. This application has the function of accurately displaying the valve opening and closing status and precisely controlling the valve, and is suitable for industrial water pipes, gas pipes and other sites;

[0028] 2. This application has both manual and automatic valve adjustment methods. Automatic adjustment is more labor-saving and convenient, while manual adjustment can still be used in the event of power failure, thus avoiding potential problems later.

[0029] 3. This application sets a plastic part on the magnet to avoid interference from stray magnetic fields on the magnet and encoder chip, thereby further improving the detection accuracy of the encoder chip. Attached Figure Description
