ピンチバルブ、機器
Document Type and Number:
Japanese Patent JP4931636
Kind Code:
B2
Abstract:
To provide a multiple string pinch valve capable of reducing pressure fluctuation of liquid in front/rear of a pressing part and suppressing damage of a tube when the tube is pressed by using a rotating body of which rotation is controlled by a motor.
In the pinch valve, the tube is not directly pressed by the rotating body, but pressed by a pressing member movable to a fixed direction by a guide. At the same time, since a tip of the pressing member is formed to have a tapered shape, pressure fluctuation in front/rear of the tube pressing part can be reduced, and damage of the tube can be prevented.
