A DEVICE FOR CONTROLLING LIQUID DRIPPING

摘要

A liquid dripping control device holds a flexible tube (4) between a stationary clamping jaw (7) and a movable clamping jaw (11), and adjusts the amount of throttling of the tube by the movable clamping jaw (11), and comprises means (6a, 6b) for detecting dripping of a liquid staying in a dropping tube (5) connected to said flexible tube (4); means (10, 12, 14) for moving at high speed the movable clamping jaw (11) to a direction of opening said flexible tube so as to rapidly start dripping of the liquid staying in the dripping tube; a means for, after detecting start of the liquid dripping, moving the movable clamping jaw (11) in a direction of throttling the flexible tube and stopping it; and a means for, after detecting subsequent dripping, moving the movable clamping jaw (11) at low speed so as to control said subsequent dripping at a predetermined speed.
