Abstract
The utility model relates to a multifunctional wellhead protector and belongs to oil field pumping unit wellhead blowout control sealing devices. A packing box blowout control pressing cap is connected with a spherical packing box in a threaded manner. The spherical packing box is rotatably connected with an eccentric guide pipe ball seat. An upper ball pressing cap is connected with the eccentric guide pipe ball seat in a threaded manner. The eccentric guide pipe ball seat is connected with a lower ball seat in an inserted manner. The lower ball seat is rotatably connected with a spherical connector. The lower ball seat is connected with a lower ball pressing cap in a threaded manner. A blowout control ball is located in the packing box blowout control pressing cap. A spring is disposed between the blowout control ball and a blowout control ball pressing cap. An O-shaped ring is disposed between the blowout control ball pressing cap and the packing box blowout control pressing cap. A rubber packing is disposed in the spherical packing box. A packing pressing cap presses on the rubber packing. The multifunctional wellhead protector has the advantages that the multifunctional wellhead protector is novel in structure, even in stress and free of environment pollution, a polished rod and a wellhead are precisely allowed to be on one vertical line, yield is increased while energy is saved, and working efficiency is increased.
Description
Technical field
The utility model belongs to oil-field oil pumper well head blowout control sealing device, refers in particular to a kind of tree protector.
Background technology
When oil producing operation, well head eccentric wear causes leakage directly to affect the operating efficiency of oil recovery, or the installation of oil pumping unit base is difficult to realize completely overlapping of polished rod axis and well head axis, makes oil pumper in operation process, motility skew, impels polished rod laterally or vertical shift.Polished rod and well head, not on a vertical line, cause well head packing eccentric wear to cause leakage of oil, contaminated environment, waste energy, reduce output.
The fixed conventional type wellhead polish rod sealing device that at present some oil field is used, is exactly in fact one and is tied and can not dissolves the fulcrum of transverse shifting.No matter how top suspension point and position of polished rod change, can only fix at the packing place linear reciprocating motion of position, makes sealed packing place become lateral force fulcrum, causes that encapsulant is one-sided is being subject to sizable horizontal friction, cause crude oil leakage, need the frequent packing that compresses and change.Cause the reduction of oil pumper operating efficiency, workload to strengthen.The old-fashioned anti-eccentric wear centralising device of use also having, although can move at random, inner transverse moves limited, can not solve for a full due polished rod skew fulcrum.
Summary of the invention
The utility model provides a kind of multifunctional well head protector, to solve well head packing eccentric wear, causes leakage, frequently changes packing and make inefficiency, increases the problem of workload.
The technical solution of the utility model is: packing box blowout-proof pressure cap is threaded with ball-type packing box, ball-type packing box and eccentric conduit ball seat are rotationally connected, upper sphere pressure cap is threaded with eccentric conduit ball seat, eccentric conduit ball seat and bottom ball seat are pegged graft, bottom ball seat is connected with ball-type connection of rotating, bottom ball seat is threaded with lower sphere pressure cap, spray-proof ball is arranged in packing box blowout-proof pressure cap, between this spray-proof ball and spray-proof ball pressure cap, there is spring, between spray-proof ball pressure cap and packing box blowout-proof pressure cap, there is O type circle, in ball-type packing box, there is rubber packing, packing pressure cap is pressed on rubber packing.
The utility model has the advantage of: novel structure, after wide-angle skew is adjusted, eccentric conduit ball seat can also be finely tuned, make so more accurately between polished rod and well head on a vertical line, have stressed evenly, eccentric wear does not leak, free from environmental pollution, Increasing Production and Energy Saving, doubles to extend application life of rubber packing, has improved operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure, ball-type connector 1, lower sphere pressure cap 2, bottom ball seat 3, eccentric conduit ball seat 4, upper sphere pressure cap 5, ball-type packing box 6, packing box blowout-proof pressure cap 7, spring 8, spray-proof ball pressure cap 9, O type circle 10, spray-proof ball 11, packing pressure cap 12, rubber packing 13, polished rod 14.
Detailed description of the invention
Packing box blowout-proof pressure cap 7 is threaded with ball-type packing box 6, ball-type packing box 6 is rotationally connected with eccentric conduit ball seat 4, upper sphere pressure cap 5 is threaded with eccentric conduit ball seat 4, eccentric conduit ball seat 4 is pegged graft with bottom ball seat 3, bottom ball seat 3 is connected 1 with ball-type and is rotationally connected, bottom ball seat 3 is threaded with lower sphere pressure cap 2, spray-proof ball 11 is arranged in packing box blowout-proof pressure cap 7, between this spray-proof ball 11 and spray-proof ball pressure cap 9, there is spring 8, between spray-proof ball pressure cap 9 and packing box blowout-proof pressure cap 7, there is O type circle 10, in ball-type packing box 6, there is rubber packing 13, packing pressure cap 12 is pressed on rubber packing 13.
Working method of the present utility model is: polished rod 14 is first passed in the middle of two spheroids from bottom to up; after being threaded with wax removal valve upper end; starting oil pumper shuts down again; at this moment this product can be automatic 360 degree adjust the central point of polished rods and well head; while needs, the central point of rotating eccentricity conduit ball seat searching polished rod and well head makes the central point of polished rod and well more accurate; in locking, lower sphere pressure cap can run well, in case of polished rod surprisingly fractures blowout hookup can automatically seal well head by down-hole pressure.
