Abstract
L'oggetto dell'invenzione è una conduttura per combustibili fluidi, la quale si estende su almeno due sistemi movibili relativamente l'uno rispetto all'altro, laddove le condutture proprie dei sistemi e preferibilmente rigide sono collegate per mezzo di una conduttura flessibile di compensazione di lunghezza. Quale conduttura flessibile è previsto un collegamento di tubolare flessibile di sicurezza (1) che è costituito di una conduttura in pressione (2) flessibile, conducente il fluido, e di una conduttura di protezione (3) flessibile, circondante a rivestimento e a distanza la conduttura in pressione, come pure di elementi di misura (5), di valutazione (6) e di commutazione (7), collegati con la cavità (4) tra la conduttura in pressione (2) e la conduttura di protezione (3), rilevando una variazione di stato della cavità (4) e reagendo alla stessa.The object of the invention is a pipeline for fluid fuels, which extends over at least two systems which can be moved relatively to each other, where the pipelines of the systems and preferably rigid are connected by means of a flexible compensation pipeline of length. As flexible conduit, a flexible flexible tubular connection (1) is provided which is made up of a flexible pressure conduit (2), conducting the fluid, and of a flexible protective conduit (3), surrounding the pipeline and covering it remotely under pressure, as well as measuring (5), evaluation (6) and switching (7) elements, connected with the cavity (4) between the pressure pipe (2) and the protection pipe (3), detecting a change in the state of the cavity (4) and reacting to it.
