A security and safety latch system for fluid couplings particularly for fluid couplings utilizing rotatable valves wherein connection and disconnection of the coupling parts is by relative rotation of the parts and the valves are rotated between open and closed positions by exterior manually operated handles. The coupling parts and the valve handles are provided with interfering surfaces which prevent the parts from being relatively rotated and disconnected until both coupling valves are closed. Further, the valve handles are provided with security latches which permit the handles to be locked in the closed position, and prevent the valve handles from being locked in the valve open position.
ystème de verrouillage de sécurité pour coupleurs hydrauliques, particulièrement pour coupleurs hydrauliques utilisant des robinets à tournant, dans lequel le couplage et le découplage se fait par rotation relative des éléments du coupleur et les robinets sont ouverts ou fermés par rotation manuelle d'une poignée extérieure. Les éléments du coupleur et les poignées des robinets sont dotées de surfaces interférentes qui empêchent leur rotation relative et leur découplage jusqu'à ce que les deux robinets du coupleur soient fermés. En outre, les poignées des robinets sont munies de loquets de sécurité qui permettent de verrouiller les poignées en position fermée et empêchent de les verrouiller en position robinet ouvert.
