  • Arrangement for connecting and disconnecting two pipe sections of a fluid transfer system
    Patent number: 6877527
    Abstract: An arrangement for connecting and disconnecting two pipe sections in a fluid transfer system. Each section includes a butterfly valve with a disk pivotally mounted inside, rotating about a swivel axis between a closed position closing the cross-section of the fluid flow and an open position opening the cross-section of the fluid flow. The swivel axes extend perpendicular to the pipe axis and parallel to each other. The swivel axes of the disks are eccentric relative to the axes of the sections to reduce the space between the disks in their closed position, when the sections are connected. The invention is useful for transferring liquefied natural gas.
