Title (EN) QUICK COUPLING WITH TWO-STAGE UNCOUPLING
(FR) COUPLEUR RAPIDE A DESACCOUPLEMENT A DEUX PHASES
Abstract:
(EN) A coupling comprising a spigot portion (10) and a socket portion (1, 3) comprising a gate valve (5) on the upstream side thereof that is open when the spigot and socket portions are coupled, and closed when they are uncoupled. The spigot portion (10) comprises an outer surface provided with a flange (14). A locking member (7) is radially movable in the socket portion and comprises a bore extending in the axial direction of the socket portion for receiving the spigot portion. The bore surface in the locking member includes two flange halves (11, 12) of which at least one consists of two substantially tapering projecting surfaces. The upstream-facing surface of the flange half (12) located upstream from the flange (14) fits at least 180° of the flange (14) on the spigot portion in the fully coupled position.
(FR) Le coupleur comporte une pièce mâle (10) et une pièce femelle (1, 3) comportant du côté amont un clapet d'obturation (5) qui est ouvert lorsque les pièces femelle et mâle sont accouplées et qui est fermé lors du désaccouplement. La pièce mâle (10) comporte une surface extérieure munie d'une collerette (14). Un verrou (7) est prévu dans la pièce femelle, mobile dans un sens radial et comportant un alésage orienté dans le sens axial de la pièce femelle et traversé par la pièce mâle. Le verrou comporte sur la surface de son alésage deux demi-collerettes (11, 12) dont au moins une est formée par deux surfaces essentiellement en forme de serpe conique. La surface orientée vers l'amont de la demi-collerette (12) qui est située en amont de la collerette (14) est susceptible d'épouser au moins 180° de la collerette (14) de la pièce mâle lorsque celle-ci se trouve dans une position d'accouplement complet.
