[0026] A connecting shaft is fixedly connected to the front of the slider 8, and a mounting groove matched with the connecting shaft is provided on the back of the cover plate 7, and the mounting grooves are distributed around the circular opening of the cover plate 7. There are ten sliders 8, and ten sliding grooves matched with the sliders 8 are provided on the front of the inner block 2. The ten sliders 8 together constitute a valve core, and the valve core composed of the ten sliders 8 is connected to the circular opening of the cover plate 7.

[0027] In addition, the diameter of the device is a polygon.

[0028] Servo motors 3 play an important role in remote control. Servo motors are motors that can control angles, speeds, and positions. They are usually composed of motors, reducers, encoders, controllers, and drivers. By combining with sensors and controllers, servo motors can realize automation functions, including remote control. Specifically, the remote control function of servo motors is mainly reflected in the following aspects: Network control: Connect the servo motor to the Internet to achieve remote monitoring and control. By remotely adjusting the parameters of the motor, checking the status of the motor, etc., the device can be remotely controlled. This network control method allows users to operate the servo motor through the Internet at any location, improving the accessibility and convenience of the device. Human-computer interaction: Connect the servo motor to a touch screen or keyboard to achieve human-computer interaction. Users can set the parameters of the motor, monitor the status of the motor, etc. through the touch screen or keyboard to achieve direct control of the servo motor. This human-computer interaction method makes remote control more intuitive and easy to use.

[0029] In addition, the high precision and high stability of the servo motor make it highly reliable in remote control. Through precise control, the servo motor can ensure the accuracy and consistency of remote control. This makes the servo motor have broad application prospects in application scenarios that require remote control, such as industrial automation, robot control and other fields. In summary, the role of the servo motor in remote control is mainly reflected in the two aspects of network control and human-computer interaction. By realizing remote monitoring and control as well as an intuitive and easy-to-use operating interface, the convenience and reliability of remote control are improved, thus greatly beneficial to the operation of the valve device. In the actual use process of the servo motor 3 of the present technical solution, corresponding waterproof and anti-oil fume measures can be added to it, thereby improving the safety performance of the servo motor 3 during use, thereby ensuring the normal use of the valve.

[0030] The working principle of the above embodiment is:

[0031] When the servo motor 3 drives the driving gear 4 to rotate, the driving gear 4 then drives the driven gear 5 meshing therewith to rotate, the driven gear 5 then drives the adjusting gear 6 meshing therewith to rotate, the adjusting gear 6 then drives the cover plate 7 to rotate, the cover plate 7 then drives the slider 8 to move along the slide groove on the front side of the inner block. Since the ten sliders 8 are distributed in a circle, when they are driven by the cover plate 7 together, the valve core formed by the ten sliders 8 forms a variable hollow, that is, the through diameter of the valve device. The through diameter shape of the device is a polygon. When the edge of the polygon moves inward or outward (each edge moves in a straight line in a direction perpendicular to the edge), the area of ​​the polygon, that is, the through diameter, will change.
