Patent

CA 2366968

There is provided a new and useful fluid conduit coupling apparatus which allows quick connection and disconnec-tion with substantially no introduction of ambient fluids or air into the process fluid. In one aspect of the invention there is provided a quick connect/disconnect coupling for a fluid conduit, the coupling comprising assemblies (12, 14) for attaching to the ends of a conduit to be connected and for subsequently mating together, each assembly comprising a normally closed channel (76, 110); means for expelling fluid from between the assemblies when the assemblies are to be connected to each other; means for preventing fluid from entering the assemblies from outside when the assemblies are being connected; means for opening the normally closed channels, means operable by the connecting of the assemblies to each other; latch means (58) for securing the assemblies together, the latch means (58) disconnectable by means of a hand operated unlatching means or by the application of a predetermined tensile force.

L'invention concerne un nouveau dispositif très utile de raccordement de conduits fluidiques, ce dispositif permettant une connexion et une déconnexion rapide sans aucun écoulement de fluides ambiants ou d'air dans le fluide de traitement. L'un des modes de réalisation inclut un raccord de connexion/déconnexion rapide pour un conduit fluidique, ledit raccord comprenant des structures (12, 14) pouvant être fixées aux extrémités d'un conduit, puis accouplées, chaque structure comprenant un canal (76, 110) normalement fermé; un dispositif servant à évacuer le fluide de l'espace qui sépare les structures lorsque celles-ci vont être connectées l'une à l'autre; un dispositif permettant d'éviter que le fluide ne pénètre dans les structures depuis l'extérieur lorsque lesdites structures sont connectées ensemble; un dispositif permettant d'ouvrir les canaux normalement fermés, ce dispositif pouvant être actionné lors de la connexion des structures l'une à l'autre; et un dispositif de verrouillage (58) permettant de fixer les structures l'une à l'autre, ce dispositif de verrouillage pouvant être désactivé au moyen d'un dispositif de déverrouillage à commande manuelle ou par l'application d'une force de tension prédéfinie.
