摘要： A downhole tool includes a tubular having an outer surface and an inner surface defining a flowbore having a longitudinal axis, and a backpressure valve cartridge arranged in the flowbore. The backpressure valve cartridge includes a valve seat and a flapper valve pivotally mounted relative to the valve seat. The backpressure valve cartridge is shiftable along the longitudinal axis to shift the flapper valve between a first position, wherein the flapper valve rests on the valve seat, and a second position, wherein the flapper valve is pivoted away from the valve seat.

摘要： A downhole tool includes a tubular having an outer surface and an inner surface defining a flowbore having a longitudinal axis, and a backpressure valve arranged in the flowbore. The backpressure valve includes a flapper valve including a first side and an opposing second side pivotally mounted to the inner surface to selectively extend across the flowbore, and a locking system mounted to the inner surface in the flowbore and selectively engageable with the flapper valve. The flapper valve is pivotable between a first position, wherein the flapper valve is free to pivot relative to the inner surface, and a second position, wherein the flapper valve is pivoted away from the flowbore and locked open by the locking system such that the first side forms part of the flowbore.
