DEVICE FOR CHOKING FLUID FLOW

摘要

A device for choking a flow of fluid in a fixed length of tube with an ac tuator simple in construction. The choking device is free of direct touch wi th the fluid inside the tube, expected not to obstruct the flow in the tube as permitted as possible at normal condition, expected to perform both detec tion and control with a single device, and further invulnerable to kinds of fluids. The device for choking a flow of fluid includes a tube holder (5) to keep a tube (1) in looped configuration, a movable part (4) energized to sq uish the looped configuration of the tube (1). Squeeze of the looped configu ration of the tube (1) gets the tube (1) collapsed to cause a snapped bent ( 2) to stop the flow of fluid (3) passed through the tube (1). Retreat of the movable part (4) results in bouncing back of the tube (1) from the collapse d bent (2), allowing the fluid (3) flowing again through the tube (1).
