Abstract
A rotary connector for selectively coupling a rotating pipe to a stationary pipe includes a housing for interconnection to the stationary pipe. A rotary stem is disposed within the housing for providing a fluid communication path between the rotating pipe and the stationary pipe. The rotary stem is selectively removable from the housing without removal of the housing from the stationary pipe. A seal is provided and is interconnected to the rotary stem and disposed between the rotary stem and the housing for sealing the rotary stem within the housing. The housing seal is selectively removable from the housing with the rotary stem. The rotary connector further includes a rotary flange for interconnection to the rotating pipe for selectively mounting the rotary stem to the rotating pipe for the transfer of torque to the rotary stem. The rotary stem can be selectively removed from the rotary flange without removal of the rotary flange from the rotating pipe. A sealing assembly is interconnected to the rotary stem and is disposed between the rotary stem and the rotary flange for sealing the rotary stem to the rotary flange. The sealing assembly is selectively removable from the rotary flange without removal of the rotary flange from the rotating pipe.
