Description
Technical field
The utility model relates to a kind of oil extraction wellhead sealing device, especially relates to a kind of hydraulic pressure Universal sealed device.
Background technology
It is production tree that mechanical oil well is used for the wellhead assembly of recover petroleum, is mainly used in hanging the tubing string in lower going-into-well, the annular space between sealing oil pipe and sucker rod, control and regulate oil well production, guarantee job execution, admission oil, casing pressure data, the daily production managements such as test and wax removal.
The parts that upper end is used for sealing space between oil pipe and sucker rod are packing box assembly, packing box component sealing is the important component part of mechanical oil recovery well head, sucker rod moves back and forth continuously, fluid pressure, moisture, fluid intermittently in being subject to well, the factors such as production wellhead and pumping unit horsehead misalign impact, attendant needs close observation to pass through repeatedly fastening packing and solves thorn leakage, and packing life cycle is shorter, also may occur security context contamination accident.Polished rod ruptures after well, and the ejection of well inner high voltage liquid is difficult to control and take measures in time.Also do not overcome at present the device of above-mentioned defect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure unique, automatically regulate packing pressure, heighten rate while recovering the oil, safe and reliable, the hydraulic pressure Universal sealed device that increases the service life.
The utility model is realized in the following way:
A kind of hydraulic pressure Universal sealed device, it is characterized in that: it comprises joint pedestal, on joint pedestal, be combined with successively grease chamber's housing and preventer, in grease chamber's housing, be combined with successively from bottom to up slip ball-type seat and universal spherical cover, top in universal spherical cover is combined with tapered sleeve and upper gland packing, bottom are combined with lower tapered sleeve and lower seal filler, between upper gland packing and lower seal filler, be combined with respectively lower spring cup, between upper lower spring cup, be provided with spring;
Described preventer is to be assembled with the concavo-convex flashboard coordinating in it by preventer shell;
On described grease chamber housing, be provided with successively from the bottom up lower liquid level window, filler and upper cover plate, be bolted and form with described grease chamber housing;
In described lower tapered sleeve, relief valve is installed, in relief valve bottom universal spherical cover, is combined with ball-and-seat;
In described lower tapered sleeve, on two described spring bases, be combined with respectively upper and lower packing up and down;
Tapered sleeve fit on has clamp nut cover on described, the male thread of clamp nut cover and the interior screwed connection of described lower tapered sleeve;
Described joint pedestal coordinates with described grease chamber housing by bolt.
The utility model has following effect:
1) structure unique, automatically regulate packing pressure: it comprises joint pedestal the device that the utility model provides, on joint pedestal, be combined with successively grease chamber's housing and preventer, in grease chamber's housing, be combined with successively from bottom to up slip ball-type seat and universal spherical cover, top in universal spherical cover is combined with tapered sleeve and upper gland packing, bottom are combined with lower tapered sleeve and lower seal filler, between upper gland packing and lower seal filler, be combined with respectively lower spring cup, between upper lower spring cup, be provided with spring; By filling engine oil in grease chamber's housing oil pocket, when sucker rod moves vertically downward, lower tapered sleeve moves down, it is large that the space that spring produces becomes, machine oil enters by ball-and-seat the space that spring produces, and when engine oil pressure reaches setting value, by relief valve, overflows back normal pressure machine oil cavity.Also can rotate preventer, drive clamp nut cover, compress or locking upper tapered sleeve, regulating spring seat is to filler thrust simultaneously.
2) adjustable universal eccentric: the device that the utility model provides prevents that sucker rod is not when packing center, and under polished rod horizontal force action, slip spheric seat moves horizontally on joint pedestal.When vertical direction regulates, sucker rod verticality changes, and slip ball-type seat top arc surface is subjected to displacement mutually, plays within the specific limits sucker rod vertical direction regulating action.When needs manual adjustments vertical eccentric is spent, adjustable jackscrew screw.
3) wellhead blowout preventor function: the device that the utility model provides falls after well because of a variety of causes when sucker rod, and upper end preventer is under spring action, and the concavo-convex flashboard of auto-closing, prevents leak of liquid in well.In the time of need to opening, exiting screw rod drives flashboard separately.
4) long service life: the device that the utility model provides utilizes sucker rod to move back and forth energy to improve between two packings pressure to zone of reasonableness by oil pressure, when pressure arrival requires, releasing pressure automatically refluxes, keep stable thrust to reach the effect of automatic adjusting sealing, and under lubrication, extend packing life cycle, prevent that well head from occurring that eccentric wear damages.
5) heighten rate while recovering the oil, safety, reliable: the utility model oil field at home enterprise, on mechanical oil well well head, all can use, can lower material and attendant's cost, and can omnirange regulate pumping unit horsehead and wellhead polish rod centering, in a pump detection period, realize packing non-maintaining, reduce and answer packing thorn blind hole mouth eccentric wear to stop the well time, heighten rate while recovering the oil.This device can be closed well head after falling polished rod in well can prevent that safety and environmental protection accident from occurring.
