Claim Text:
1. An Axially Aligned Rotationally Adjustable Flow Control Valve capable of complete shutoff for controlling the flow of fluids comprising; an inlet section having an external circular surface and a internally circular hollow bore having a central axis, said inlet section having a distal end adapted to interface with a piping structure, a securement means and a conically divergent outlet described about said distal end of said inlet section; and, an outlet section, having an internally circular hollow bore having a central axis coincident to said central axis of said inlet section, having a distal end adapted to interface with a piping structure, a securement means, a proximally located secondary flow control means positioned within a securement enclosure, where said enclosure contains a sealment means, and where central axis of said secondary flow control means is coincident to said central axis of said hollow bore, and an angular displacement guide externally distally located on exterior flange of said outlet section and, a central body section having an external circular bore and an internally circular hollow bore throughout the length of said section, said central body section hollow bore having a coincident central axis common to said hollow bore of said inlet section and said outlet section, a circular venturi sensing means proximally located and appurtenant to said conically described distal end of said inlet section, a pressure differential measurement means perpendicularly related and in communication with said circular hollow bore, a distally located primary flow control means, a primary flow control sealment means positioned within a securement enclosure, where axis of rotation of said primary flow control is coincident to said central axis of said inlet and said outlet sections, a set of leakage prevention O-Rings located near terminating ends of said central body, said rings interfacing with said external surface of said inlet and outlet sections to prevent leakage as said internal bore of said central body rotates about said external bores of said inlet and outlet sections, a proximally located external boss, said boss containing a threaded bore extending to said internal hollow bore through which a set screw is tighten to prevent rotation of said central body about said inlet and outlet section and a distally located external angular displacement index.
