LIQUID FILLING VALVE AND DRIVE CONTROL METHOD OF LIQUID FILLING VALVE

摘要

PROBLEM TO BE SOLVED: To fully close a filling valve reliably while freely adjusting the opening of the filling valve.SOLUTION: A filling valve 20 comprises: a valve body 24 disposed in a flow channel 23 through which a liquid flows; a valve seat 21 on which the valve body 24 is seated in a flow direction of the liquid; a movable body 25 disposed outside the flow channel 23; and a driving device 30 for driving the movable body 25. The driving device 30 includes a motor 33 which outputs a driving force for driving the movable body 25 and variably controls at least a position among the position and speed. The valve body 24 follows the movement of the movable body 25 by a magnetic force acting between the valve body 24 and the movable body 25.SELECTED DRAWING: Figure 2
