The invention relates to the technical field of
petroleum drilling directional equipment, in particular to an easy-to-replace continuous oil
pipe hydraulic directional device which comprises an upperjoint, a
clutch shaft, a
clutch sleeve, a spline sleeve, a spline shaft
piston, a transposition joint, a cylinder sleeve, a core
pipe, a throttling element and a lower joint. The inner side of the lower part of the
upper joint is fixedly connected with the
clutch shaft, the outer side of the upper part of the clutch shaft is sleeved with the clutch sleeve, the outer side of the lower part of the clutch shaft is sleeved with the spline sleeve, the inner side of the lower part of the spline sleeve is provided with the spline shaft
piston arranged in the vertical direction, the outer side of thelower part of the spline shaft
piston is sleeved with the transposition joint, the outer side of the transposition joint is provided with the cylinder sleeve, the inner side of the upper part of the cylinder sleeve is fixedly connected with the outer side of the lower part of the transposition joint, the inner side of the lower part of the cylinder sleeve is fixedly connected with the lower joint,the inner side of the upper part of the lower joint is provided with the throttling element capable of generating pressure drop, and the lower part of the core
pipe is sleeved with the inner side ofthe upper part of the lower joint and is seated on the upper part of the throttling element. The easy-to-replace continuous oil pipe hydraulic directional device is reasonable and compact in structureand convenient to use, and has the advantages that the tool face angle is flexible to adjust, and precision is high.
