ABSTRACT:
A quick disconnect coupling that may be used in fluid systems for fast coction or disconnection of hoses or hoses to pipes. The coupling is especially useful where it is necessary to avoid any leakage or spillage. The coupling employs a female section and a male section wherein both sections employ O-ring joints that permit easy hand tight assembly and disassembly without any leakage. The O-ring joints permit considerable variation in clearance between mating flanges and thus permit the use of removable locking rings to lock the flanges and prevent their relative rotation. The female section employs a ball bearing mounted rotatable nut that permits rapid connection and disconnection without spillage. The rotatable nut has minimum axial movement that permits a close diameter tolerance so that longitudinal or lateral relative motion between the female and male members will not result in leakage. Also the degree of rotation of the rotatable nut permits flow rate regulation of the fluid passing through the coupling. An internal valve actuating system permits rapid and positive actuation and provides for a double seal in the fully open position. Sealing end caps are also employed to prevent contamination from entering the disconnected female and male sections and also provide further sealing to prevent leakage.
