Flex joint incorporating enclosed conductors |
摘要 |
A flex joint for an elongate oil tool which permits flexure and bending while yet protecting electrical conductors is disclosed. The duplicated flex joint incorporates a hollow knuckle having a passage therethrough received in a mating and confining socket terminating in a passage. The knuckle and socket form a flex joint. The flex joint is pinned so that rotation in a conic angle is permitted while rotation of the two components relative to one another is forbidden. The passage is periodically closed by means of a transverse plug, an electrical feedthrough permitting electrical conductors to extend through said plug. The passage is further protected from the intrusion of fluids from the well borehole by means of a spring loaded piston compensating pressurized sealed oil system which operates in an annular space on the exterior of the passage.
