Abstract

This article describes a controller which allows the controlled flow of a fluid media through a flexible tubing, maintaining smooth passage of the media through the tube, with no abrupt turns or edges that the media must pass through to the output. Moreover, there are no dissimilar materials that the media must pass from input through output; therefore, this system does not introduce contaminants into the media.

Flow Controller

This article describes a controller which allows the controlled flow of a fluid media through a flexible tubing, maintaining smooth passage of the media through the tube, with no abrupt turns or edges that the media must pass through to the output. Moreover, there are no dissimilar materials that the media must pass from input through output; therefore, this system does not introduce contaminants into the media.

A flexible tube of a varied diameter is inserted between two spherical buttons 11, 12. Button 12 is fixed to a frame 15, and button 11 is fixed to a fine-threaded rod 14 which, in turn, is threaded to the frame. The opposite end of the threaded rod terminates in a fixed knurled knob. The spherical button configuration allows uniform, nondamaging, smooth compression of the flexible tubing.
