DEVICE FOR CHOKING FLUID FLOW

摘要

A device for choking a flow of fluid in a fixed length of tube with an actuator simple in construction. The choking device is free of direct touch with 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 detection 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 squish the looped configuration of the tube (1). Squeeze of the looped configuration 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 collapsed bent (2), allowing the fluid (3) flowing again through the tube (1).
