Description

Technical Field

[0002] With the continuous improvement of the quality of life, some water treatment equipment (such as water purifiers, instant electric kettles, etc.) need to accurately adjust the water flow. However, current water treatment equipment generally adjusts the water flow by controlling the input power of the water pump, and the water flow regulation is not accurate enough. Ball valves, as a common valve, are generally used to cut off the fluid in the pipeline, but ball valves can also be used to adjust the flow. By changing the opening of the valve, the area of ​​the fluid passing through the valve is changed, thereby changing the flow rate.

[0003] Ordinary ball valves or V-type ball valves are generally divided into pneumatic and electric. Pneumatic valves are often used for fully open and fully closed types, and electric valves are generally used for regulating types. The existing electric ball valves on the market generally have the problem of insufficient regulation accuracy. In order to solve the shortcomings of the existing technology, we propose a high-precision flow regulation device. Utility Model Content

When flow regulation is required, the stepper motor 7 is started, and the stepper motor can drive the rotating shaft 9 at the bottom to rotate through the motor shaft 12. At the same time, the rotating shaft 9 can drive the ball valve core 13 inside the ball valve body 1 to rotate.
