Flow valve installation and removal apparatus

Claim 1

A well installation comprising: a. a well tubing having a plurality of tubing mandrels each having a main bore therethrough with an orientation sleeve mounted in the main bore and a valve receiving side pocket offset from the main bore, said orientation sleeve including: 1. an elongated hollow tubular body having an upper and lower end; 2. said lower end extending upwardly at an angle relative to the longitudinal axis of said tubular body to form a sloping guide surface which extends upwardly and away from the offset pocket; 3. a first slot extending longitudinally of said tubular body from the highest portion of said guide surface, said first slot terminating in spaced relation to said upper end of said tubular body; 4. a second slot extending from the upper end of said first slot to the upper end of said tubular body; and 5. said second slot being substantially smaller in width than said first slot to form a pair of aligned shoulders at the juncture of said first and second slot which are spaced from each other by said second slot whereby debris may discharge from said first slot through said second slot and into the tubing; b. guard and guide means above the valve receiving side pocket and including spaced sides facing the main bore and having vertical edge surfaces and an inner upwardly tapered end to guide a valve into the valve receiving side pocket; c. a support body adapted to be moved through the tubing and mandrels; d. a movable body carried by and longitudinally movable relative to the support body; e. a longitudinal guide key having an upwardly directed shoulder and an inclined surface facing downwardly, pivotally carried by said movable body for outward movement from said movable body and movable downwardly through said sleeves but an upward movement of said movable body engagable with the lower end of any sleeve immediately thereabove to slide along said first slot means and engage said aligned shoulders; f. shifting tool means pivotally supported from said support body and adapted to support a valve handling support; g. cooperating releasing means on said support body and movable plunger initially holding said shifting tool means aligned in the main bore; and h. cooperating shifting means connected between said shifting tool means and said support body for shifting said shifting tool means into the side pocket when the releasing means is actuated.
