A fine-tuning flow regulator

Abstract

The present invention discloses a fine-tuning flow regulator, including a turntable, a first plug-in ring fixedly arranged in the middle of the turntable, a rotating ring fixedly arranged on the inner wall of the first plug-in ring, a fixed tube movably plugged into the surface of the rotating ring, an adjustment ring fixedly arranged in the middle of the rotating ring, an adjustment cavity opened on the surface of the adjustment ring, and a second plug-in ring fixedly arranged on the top of the fixed tube corresponding to the position of the adjustment ring. The present invention drives the rotating ring to rotate by cooperating with the first plug-in ring of the turntable, and drives the adjusting cavity to rotate through the adjusting ring. Since the depth of the adjusting cavity gradually decreases from top to bottom, the adjusting cavity changes the depth of the position corresponding to the liquid inlet hole, thereby changing the flow speed of the liquid in the infusion tube in the adjusting cavity, and then changing the flow rate of the droplets. The flow rate of the liquid can be displayed by the scale line, which is more accurate than that of the ordinary infusion device, thereby achieving the purpose of facilitating the precise control of the droplet speed.
