ABSTRACT:
A kelly valving apparatus for controlling flow of fluid through a kelly and drill string comprises a rotatable tubular section having a fluid conveying bore adapted to be attached to the drill string at the kelly with a valve associated valve body valving the flow of fluids through the bore. A remotely operable operator is rotatable with the rotatable tubular section, operably engaging the valve for moving the valve between positions which open and close the bore, the operator including at least one hydraulic cylinder having an extensible ram actuated by hydraulic fluid, and linkage is connected to the valve and the hydraulic cylinder so that extension/contraction of the ram effects an opening or closure of the bore. A liquid interface fluid collector ring is positioned adjacent the rotatable tubular section for transmitting pressurized hydraulic fluid to the hydraulic cylinder, even during spinning of the cylinder with the tubular section. A source of controllable pressurized hydraulic fluid is connectable to the fluid collector ring for supplying pressurized hydraulic fluid thereto.
