Abstract

Oppfinnelsen vedrører sammenkobling av kanalelementer ved hjelp av to plane flenser som er fastmontert ved deres ender som skal forbindes innbyrdes. Oppfinnelsen foreslår en ringformet tetning (1), som har koaksiale indre og ytre sideflater (2, 3) i form av rotasjonsflater, karakterisert ved at den også har et symmetriplan som passerer gjennom omdreiningsaksen (4) for nevnte sideflater og har første og andre kontaktsoner (6, 7) som ligger i henholdsvis første og andre plan (8, 9), idet nevnte første og andre plan (8, 9) skjermer hverandre for å danne en V som har en kant vinkelrett på symmetriplanet. Oppfinnelsen er anvendbar i alle industrier hvor væskefor- mede eller gassformede fluider, pulvere eller annet partik- kelmateriale transporteres, spesielt i oljeindustrien.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the coupling of duct elements by means of two flat flanges mounted at their ends to be interconnected. The invention proposes an annular seal (1) having coaxial inner and outer side surfaces (2, 3) in the form of rotating surfaces, characterized in that it also has a plane of symmetry passing through the axis of rotation (4) for said side surfaces and has first and second contact zones. (6, 7) located in the first and second planes (8, 9), respectively, said first and second planes (8, 9) shielding each other to form a V having an edge perpendicular to the plane of symmetry. The invention is applicable to all industries where liquid or gaseous fluids, powders or other particulate matter are transported, especially in the oil industry.
