Rapidly releasable pressure-tight connection system and use of a per se known quick coupling for a rapidly detachable pressure-tight connection system of pipelines

摘要

It is a rapidly detachable pressure-tight connection system for pipelines, in which a fluid material, in particular a melt at temperatures above 100°C. flows, is proposed. It comprises a conventional rapid-action coupling (4), which a receiving element (5), a in the receiving element (5) engaging end fitting device (9) and a tensioning element (6) for clamping the receiving element (5) and of the male element (9) has to one another. It is further two threaded rings (3) is provided, which in each case by means of a axially fixed connection to an end piece of the pipelines (1, 2, 15, 16) are attachable. The receiving element (5) and the plug element (9) each have an internal thread which, on the threaded rings (3) is threadingly. In the receiving element (5), a sealing element (8) is recorded. On the position of the threaded rings (3) in relation to the respective pipe end and the screw-in length of the pickup element (5) and of the male element (9) in relation to the threaded rings (3) is a sealing gap (14) for the sealing ring (8) between the pipe ends can be adjusted in the closed state of the connection system.
