Abstract

PROBLEM TO BE SOLVED: To positively perform the opening and closing operations of a tube through which fluid flows, simplify a plurality of tube operations, and thereby enhance operating performance in connection with a fluid feeding valve controlling fluid such as medicines and the like automatically or by a remote control. SOLUTION: The multiple small type pinch valve is so constituted that it can be easily disassembled into a tube guide 5 serving as a casing lower part as well, and a casing upper part 6 acting as a base member for a motor 11, cams (1) 3 and the like, and a plurality of flexible tubes 1 and 2 through which fluid such as medicines and the like flows, are lined up so as to be held in grooves in a parallel form within the tube guide 5. Over the tubes 1 and 2, one shaft 4 is disposed while being perpendicularly intersected with these tubes, and a plurality of cams (1) 3 are mounted onto the shaft 4. Each cam is basically circular in shape, but a part of its circular are shape is cut and formed into a bow shape. The rotation of each cam (1) 3 thereby allows the fluid pass of each tube to be opened/closed, so that the flow of fluid is thereby controlled.

1. A plurality of flexible tubes through which a liquid such as a drug flows inside are held in parallel by respective grooves of a tube guide provided in parallel at the lower part of the pinch valve main body, and the plurality of tubes are held. A shaft is orthogonally arranged on the above, a plurality of cams are attached to the shaft, and the rotation angle of a motor connected directly to the shaft or through a gear is controlled to control the plurality of the plurality of cams. Each tube is configured to be opened and closed independently by a cam, and further, the casing, which accommodates the cam, the shaft, and the drive motor, and the tube guide are configured as a fitting type lock mechanism for disassembly and assembly. Multiple small pinch valve characterized by making it easy.
