Abstract
The utility model discloses an on-pump oil pipe connecting device. The device is characterized in that an inner pipe is sleeved with a friction mechanism; the inner pipe and the friction mechanism are connected through a track pin; a sleeve gasket is mounted at the lower part of the inner pipe; a communication hole is formed at the lower part of the inner pipe and covered by the sleeve gasket; the sleeve gasket and the inner pipe are connected through a locking ball; an inner hole of a relief sleeve is sleeved outside the sleeve gasket; the lower end of the relief sleeve is below the locking ball; a spring is arranged on the sleeve gasket and is positioned in the relief sleeve; the relief sleeve and the friction mechanism are separated; and a track groove is formed on the outer surface of the inner pipe and comprises an upper track groove and a lower track groove. According to the utility model, when the oil pipe is required to connect, the connection can be completed through lifting the oil pipe, rotating the oil pipe and lifting the oil pipe again in sequence; the time of connection can be controlled by a worker at will; and as the operation of connecting the oil pipe is avoided when the oil pipe drops, and a packer with a rotary seat seal, such as the type of Y221, is arranged at the lower part of a pipe column, during seat sealing, the oil pipe is dropped after being rotated, which is different with the operation of opening the connecting device, oil leakage is avoided. Therefore, the oil pipe connecting device is reliable in operation and high in operation success rate.
Description
Technical field
The utility model is the underground equipment that oil field pumping well is used, and is oil pipe intercommunicating device on a kind of pump.
Background technology
Existing intercommunicating device kind is a lot, and great majority are to use in the well that sucker rod is opened draining or the ground drop-in tool is opened draining.If behind the intercommunicating device rod parting of these types, sucker rod can not be carried out, can't realize draining.Be 96238554.9 1 kinds of split type oil riser bleeders such as the patent No., its brace type solution lock assembly will contact and draining with the draining assembly when carrying oil pipe, will cause device to open leakage of oil when running in operation workman operate miss or the process of going into the well when new situation needs to carry oil pipe, make operation unsuccessful.
Summary of the invention
The purpose of this utility model provides oil pipe intercommunicating device on a kind of pump, avoids the deficiency of existing intercommunicating device, when carrying oil pipe to the work of the operation realization intercommunicating device of oil pipe.
The purpose of this utility model is achieved in that and comprises inner tube, friction mechanism, track pin, spring, discharge cover, lock ball, sealing shroud, friction mechanism is sleeved on outside the inner tube, inner tube is connected by track pin with friction mechanism, sealing shroud is installed in the inner tube bottom, linked hole is arranged at the inner tube bottom, linked hole is covered by sealing shroud, sealing shroud is connected by lock ball with inner tube, discharge the cover endoporus and be placed in outside the sealing shroud, discharge the cover lower surface and be under the lock ball, spring is arranged on the sealing shroud, spring is in and discharges in the cover, discharge cover and separate with friction mechanism, inner tube outer surface has rail groove, and rail groove divides get on the right track groove and lower railway groove.
The beneficial effects of the utility model are: the top rotation pipeline of carrying behind the oil pipe is carried oil pipe UNICOM on again during the utility model UNICOM, when UNICOM can arbitrarily be controlled by artificial, need not drop into instrument and the sucker rod of opening intercommunicating device, be not subjected to the impact of rod parting, do not propose the continued operation that rotation pipeline behind the oil pipe is carried oil pipe on again because do not have during lower oil pipe, the band packer setting just like the rotation of Y221 type in tubing string bottom is lower drain line behind the rotation pipeline when setting, different from the operation of opening intercommunicating device, the leakage of oil so can not cause action, therefore, the utility model reliable operation, job success ratio is high.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
Fig. 2 is the get on the right track expanded view of groove of inner tube outer surface among the embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model comprises inner tube 1, friction mechanism 2, track pin 3, spring 4, discharges cover 5, lock ball 6, sealing shroud 7.Friction mechanism 2 is sleeved on outside the inner tube 1, inner tube 1 external surface has rail groove, rail groove divides get on the right track groove 8 and lower railway 10, inner tube 1 is connected by track pin 3 with friction mechanism 2, track pin 3 can be in inner tube 1 appearance and rail groove in move, sealing shroud 7 is installed in inner tube 1 bottom, linked hole is arranged at inner tube 1 bottom, and linked hole is covered by sealing shroud 7, on the linked hole, under sealing ring is arranged, sealing shroud 7 is connected by lock ball 6 with inner tube 1, discharge cover 5 endoporus and be placed in outside the sealing shroud 7, release is overlapped 5 lower ends and is under the lock ball 6, and spring 4 is arranged on the sealing shroud 7, spring 4 is in and discharges in the cover 5, and the effect of spring 4 is to support to discharge cover 5.Discharge cover 5 and separate with friction mechanism 2, guarantee that pumping pipe string produces when flexible in oil pumping process, the inner and inner tube 1 of friction mechanism 2 relatively moves, and friction mechanism 2 outsides do not relatively move with sleeve pipe, avoid friction mechanism 2 and sleeve pipe to be worn.Brake pad external diameter on the friction mechanism 2 can change with casing inner diameter greater than sleeve pipe.The effect of friction mechanism 2 is to produce axial force, and promotion discharges cover 5 when the needs draining, sealing shroud 7 moves.The utility model is connected on the oil well pump, track pin 3 is in 8 li of the grooves of getting on the right track, friction mechanism 2 can not contact and discharge cover 5 when tubing string produced wriggling in oil pumping process, sealing shroud 7 can not move, the utility model is in sealing state during oil well pump work, when lower subjob is carried oil pipe and is needed draining, carry oil pipe first, under the frictional force effect between friction mechanism 2 and the sleeve pipe, friction mechanism 2, it is motionless to discharge cover 5, make track pin 3 be in middle part distortion place 9 places of the rail groove on inner tube 1 external surface, carry oil pipe on again behind the rotation pipeline, be in 10 li of the lower railway grooves of the rail groove on inner tube 1 external surface at the frictional force effect lower railway pin 3 between friction mechanism 2 and the sleeve pipe, because spring 4, discharge cover 5, sealing shroud 7, lock ball 6 is up with inner tube 1, release is overlapped 5 motionless after discharging cover 5 and contact with friction mechanism 2 bottoms, sealing shroud 7, lock ball 6 continues up with inner tube 1, spring 4 is compressed, lock ball 6 enters and discharges cover 5 inner reamings place, lock ball 6 loses the locking action to sealing shroud 7, inner tube 1 continues up, friction mechanism 2, discharge cover 5, sealing shroud 7 is motionless, makes the linked hole internal and external antithetical couplet pass-out oil on the inner tube 1.
