Through the overlap of the sealing ring 14 and the adjusting ring 6, the control valve body 1 can be sealed to block the fluid backflow. A driving assembly is arranged on the surface of the control valve body 1, and the driving assembly consists of a servo motor 15, a transmission shaft 16, a worm 17 and a worm wheel 18. The servo motor 15 is fixedly connected to the surface of the control valve body 1, the transmission shaft 16 is fixedly connected to the output end of the servo motor 15, and the transmission shaft 16 is rotationally connected to the inner wall of the control valve body 1, the worm wheel 18 is fixedly connected to the surface of the threaded rod 4, and the worm wheel 18 is meshed with the worm 17, which is used to drive the adjusting ring 6 to move laterally, so as to control the flow rate by adjusting the fluid flow gap.
[0022] Specifically, the limiting mechanism is composed of a limiting groove 7 and a limiting slider 8. There are multiple limiting grooves 7, and the multiple limiting grooves 7 are all opened inside the control valve body 1, which are used to connect multiple limiting sliders 8, thereby improving the adjustment stability of the adjustment ring 6.
