Description
Technical field
The present invention relates to oil drill rocker field, in particular it relates to a kind of, there is the segmented oil drill rocker sealing structure.
Background technology
Under the conditions of normal geology, the oil drilling degree of depth reaches thousands of rice, and Special section is up to upper myriametre deep.For the length of drilling rod of oil drilling generally at about 10 meters, along with the increase joint of drilling depth is linked in sequence the drilling rod of scale length, these drilling rods coupled together are if there is damage, then whole drilling rod can only be changed, not only waste material, add cost, and too increase maintenance difficulty, it is unfavorable for using, it is provided with segmented oil drill rocker, but existing segmented oil drill rocker sealing is not fine, segmented oil drill rocker in use can make the liquid in oil drill rocker reveal in the joint of segmented oil drill rocker, the leakage of internal liquid not only results in the poor sealing of drilling rod, and liquid flows to the flank for connecting, poor connectivity can be caused, liquid likely can be caused to reveal in a large number or the disconnection of drilling rod.
Summary of the invention
The technical problem to be solved is to provide a kind of in the segmented oil drill rocker of leakproof, the problem leaked outside with the internal flow overcoming existing segmented oil drill rocker poor sealing to cause.
The present invention solves the problems referred to above and be the technical scheme is that have the segmented oil drill rocker sealing structure, including main rod body, fittings body, main rod body and fittings body are internally provided with the through hole running through main rod body and fittings body, one end of main rod body is provided with male connection, the inwall of the other end is provided with internal thread, the external diameter of male connection is less than main rod body, fittings body one end is provided with the female adapter coordinated with male connection, the other end is provided with taper joint, the end of male connection offers some oval recess coordinated with sealing ring, female adapter offers and groove with the place of cooperation of the end of male connection, groove coordinates with sealing ring.nullThe structure of sealing ring is the oval projection that one end is provided with that quantity coordinates with oval recess with shape，The other end is planar structure，This planar structure is consistent with the width with groove，The degree of depth is higher than the degree of depth of groove，It is easy to sealing ring and is reserved with the space of compression，Before main rod body connects with fittings body，In first sealing ring bossing being inserted oval recess one to one and tight by hand pressure，Make the planar structure part of the groove part alignment sealing ring of female adapter again，Slowly tighten until twisting motionless，During tightening，Sealing ring realizes owing to being squeezed sealing，Thus avoid the flank draining to main rod body and fittings body junction outside the fluid of through hole，The present invention is by being arranged at, at the end face of male connection, the oval recess that sealing ring coordinates，Use with the groove fit in female adapter，Not only increase sealing property，And the insertion being easy to sealing ring is allowed to difficult drop-off.
Further, the degree of depth of the described groove coordinated with sealing ring of female adapter is 10mm-15mm.This degree of depth both can guarantee that sealing ring did not came off in groove, it is ensured that sealing effectiveness, avoids difficulty of processing and the waste of material that groove causes the most deeply simultaneously, thus has saved cost and man-hour.
Further, main rod body is provided with step surface with the excessive place of male connection, and step surface is provided with the annular groove coordinated with sealing ring, and the face that female adapter end coordinates with step surface is also equipped with the annular groove I coordinated with sealing ring.After main rod body is connected with fittings body, annular groove, annular groove I and sealing ring with the use of can well intercept, oil drill rocker is outside and interior bone, it is achieved the sealing of through hole, make the working environment in through hole not affected by drilling rod outer space environment.
Further, the outer wall of main rod body is symmetrically arranged with two to rise as high as the banks.Instrument can be symmetrical when clamping clamping oil drill rocker, stress balance, the workload of staff can be reduced, and can prevent the outer wall of oil drill rocker from skidding.
Further, fittings body outer wall is additionally provided with wear-resistant sleeve.During oil drilling, drilling-rod external wall produces friction with the borehole wall, the friction causing drilling rod is impaired, badly influence security and the service life of drilling rod, the present invention arranges wear-resistant sleeve by the outer wall at oil drill rocker, when avoiding oil drilling, the borehole wall and oil drill rocker directly contacts friction, prevent oil drill rocker impaired, thus improve the security of oil drill rocker, reliability, improve service life simultaneously.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by being arranged at, at the end face of male connection, the oval recess that sealing ring coordinates, and uses with the groove fit in female adapter, not only increases sealing property, and the insertion being easy to sealing ring is allowed to difficult drop-off.
2, the present invention arranges wear-resistant sleeve by the outer wall at oil drill rocker, it is to avoid during oil drilling the borehole wall and oil drill rocker directly contact friction, prevent oil drill rocker impaired, thus improve the security of oil drill rocker, reliability, improve service life simultaneously.
3, the present invention by annular groove, annular groove I and sealing ring with the use of can well intercept, oil drill rocker is outside and interior bone, it is achieved the sealing of through hole, make the working environment in through hole not affected by drilling rod outer space environment.
