COUPLAGE POUR LA LIAISON SIMULTANEE DE PLUSIEURS CONDUITES TUBULAIRES ETROITEMENT VOISINES

摘要

The invention describes a coupling for the simultaneous connection of a plurality of closely adjacent pipelines, preferably of three lines which are laid symmetrically around a centre point and on whose end which is to be connected in each case pairs of bushes or insertion pieces are placed which are sealed with respect to one another when they are pressed into one another. In this case, the pipeline ends are joined via a flange pair with the aid of a connecting screw which acts in the centre of the flanges. The pipeline ends are in this case arranged on a concentric circle around said screw, in order to obtain an even compression force. Sealing takes place without any seals via a cone-cone connection. The coupling is very simple in its construction and can be easily manipulated in a very confined space under remote control, in very severe spatial conditions.
