CENTERING SYSTEM FOR COUPLING FOR IRRIGATION SYSTEM

摘要

A coupling for conveying fluid between a component of a fluid system and an insertion end of a conduit includes a coupling body with an internal bore. The insertion end of the conduit is introduced into a receiving end of said bore. A conduit centering structure is rigidly attached to the coupling body in axial alignment with the axis of the receiving end of the bore. A gripping mechanism fixes the position of the insertion end of the conduit in the receiving end of the bore, and a release mechanism slidable relative to the coupling body into a disengaging position induces the gripping mechanism to release the insertion end of the conduit. The conduit centering structure is a conduit guide or a conduit sleeve that projects from the coupling body within and in axial alignment with the receiving end of the bore. The first end of the guide sleeve is secured to the coupling body interior of the bore; the second end is configured with an encircling exterior bevel to enter the insertion end of a fluid conduit introduced into the coupling. The outer surface of the guide sleeve and the opposed interior surface of the bore define an annular gap configured to receive the wall of the insertion end of the conduit.
