SINGLE LINE QUICK CONNECTOR (SQC), A SYSTEM COMPRISING THE SINGLE LINE QUICK CONNECTOR AND METHOD OF OPERATING.

摘要

It is described a single line quick connector (10), a system comprising the connector (10) and associated method, for connecting a hydraulic, chemical or water fluid line (20) to a fluid connection interface (2) on a component (1), wherein the connector (10) comprises: an outer housing (11) comprising a tool (12) in one axial end thereof for operation by a tool (3), a flow bore (14) for fluid connection with the fluid connection interface (2) on the component (1), a screw element (13) which is rotationally movable and axially fixed relative the outer housing (11), wherein the screw element (13) extends in a longitudinal direction of the connector (10) and comprises external threads (15) along a part of its axial length and further comprises a termination (16) which is operable by the tool (3), a collet sleeve (17) which is rotationally fixed and axially movable relative the outer housing (11), wherein the collet sleeve (17) further comprises internal threads (18) for cooperation with the external threads (15) on the screw element (13), and wherein the collet sleeve (17) comprises a plurality of collet fingers (19) in an axial end thereof for connection to the fluid connection interface (2) on the component (1), and, a fluid line insert (23) comprising a groove (24) for a coupler (25), wherein the outer housing (11), the screw element (13) and the collet sleeve (17) are arranged such that: a rotation of the screw element (13) in a first direction results in an axial movement of the outer housing (11) relative the collet sleeve (17), and thus the collet fingers (19), in a first axial direction, and a rotation of the screw element (13) in a second direction, opposite of the first rotational direction, results in an axial movement of the outer housing (11) relative the collet sleeve (17), and thus the collet fingers (19), in a second direction, which is opposite to the first axial direction, wherein the outer housing (11) comprises a through-going opening (21) () and the collet sleeve (17) comprises at least one recess (22) between neighboring collet fingers (19), wherein the through-going opening (21) and the at least one recess (22), when connected, are configured to accommodate the fluid line insert (23), and wherein the fluid line insert (23) is connectable to the fluid line (20). The is further described a method of overriding a malfunctioning single line quick connector which is in an engaged position locked to the connection interface on the component in order to release the connector from the engaged relationship with the component.
