Abstract
The invention discloses a pumping unit polished rod centering connecting device for connecting a well head tee pipe of an oil field pumping well with a plurality of packing boxes, consisting of a well head tee junction cavity, a translational movable ball seat, a movable ball joint connector, a nylon lining and a ball joint press cap , wherein, the translational movable ball seat is arranged inside the well head tee junction cavity; the movable ball joint connector is arranged inside the transitional movable ball seat; the nylon lining is sleeved inside the movable ball joint connector; the ball joint press cap is in threaded connection with the well head tee junction cavity. The invention replaces the prior inflexible connection of collar clamps and can butt joint with various packing boxes; the structure is simple, convenient and compact, and the device has offset and centering functions under the effect of the translational ball seat and a ball joint, thereby a polished rod is made to be automatically centered. Therefore, the invention solves the environmental pollution problem due to eccentric wear and oil leakage of packings, and has the advantages of reduction of personnel labor intensity, reduction of material consumption and improvement of management level.
Description
Technical field
The present invention relates to the linkage between a kind of oil field pumping well well head tee piece and the multiple packing box, especially a kind of oil-extractor polish-rod centering linkage.
Background technology
Each oil field is in using the oil pumper manufacturing process at present, often since when the ground building is not firm, oil pumper is uneven, " U " type bolt causes the polished rod motion on the walking beam middle (center) bearing influence of factors such as vibration increase, job execution all can cause polished rod and well head to misalign, cause the generation of packing eccentric wear, oil leakage phenomenon, contaminated environment in various degree, reduce the application life of packing, increase management difficulty, material consumption and personnel labor.In addition, existing tuningout, aligning technology all be with the well head packing box be one, its defective is that tuningout and aligning can not use simultaneously, and complex structure, can not be connected with multiple packing box.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of oil-extractor polish-rod centering linkage, and it not only can automatic deflection adjusting, aligning, centering, but also prolongs the application life of packing.
For solving the problems of the technologies described above, the present invention takes following technical measures: a kind of oil-extractor polish-rod centering linkage, form by well head threeway connection cavity, the movable ball seat of parallel-moving type, movable bulb connector, nylon bush, bulb pressure cap, the movable ball seat of described parallel-moving type is seated in the well head threeway and connects in the cavity, movable bulb connector is seated in the movable ball seat of parallel-moving type, nylon bush is socketed in movable bulb connector inside, and the bulb pressure cap is connected cavity by being threaded with the well head threeway.
The movable ball seat of parallel-moving type bottom is equipped with sealing ring, between movable ball seat of parallel-moving type and the movable bulb connector joint ring is installed, and movable bulb connector top is with oval pad.
The present invention's beneficial effect compared with prior art is: this device has replaced the rigid connection of original clip, can carry out with multiple packing box to dock; The structure simple and compact makes it have the function of tuningout, aligning under translation ball seat and bulb effect, makes the polished rod automatic centering; Thereby solved because the problem of environmental pollution that the leakage of oil of packing eccentric wear causes reduces staff labor intensity, reduced material consumption, improved managerial skills.
Description of drawings
Fig. 1 is a structural representation of the present invention
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of oil-extractor polish-rod centering linkage, connect cavity 1 by the well head threeway, the movable ball seat 3 of parallel-moving type, movable bulb connector 8, nylon bush 5, bulb pressure cap 7 is formed, the movable ball seat 3 of described parallel-moving type is seated in the well head threeway and connects in the cavity 1, the bottom is equipped with O RunddichtringO 2, between movable ball seat 3 of parallel-moving type and the movable bulb connector 8 joint ring 4 is installed, movable bulb connector 8 is seated in the movable ball seat 3 of parallel-moving type, nylon bush 5 is socketed in movable bulb connector 8 inside, movable bulb connector 8 tops are with oval pad 6, and bulb pressure cap 7 is connected cavity 1 by being threaded with the well head threeway.
During use, the well head threeway connects cavity 1 bottom and well head tee piece by being threaded, and the movable ball seat 3 of parallel-moving type connects cavity 1 inside in the well head threeway can be parallel all around mobile, reaches the tuningout effect; Movable bulb connector 8 can freely swing in the movable ball seat 3 of parallel-moving type, reaches the aligning effect; Nylon bush 5 is socketed in movable bulb connector 8 inside, further regulates polished rod and reaches centering; Oval pad 6 is enclosed within movable bulb connector 8 tops, according to the backlash freedom adjustment in the well head threeway connection cavity 1, treats to compress bulb pressure cap 7 after the wellhead polish rod centering, finishes the process of aligning, tuningout, centering.Movable bulb connector 8 inside can be used as one-level packing chamber and use.
