Description
Technical field
The utility model relates to a kind of oil pumping polish rod levelling sealer that is used for the oil exploitation system.
Background technology
In the oil exploitation operation, in oil well, make rectilinear motion up and down reciprocatingly by the oil pumping notes plug that oil pumper drive oil pumping polish rod drives in the oil well again, underground oil is released.Oil well is a steel pipe that always reaches oilbearing stratum from ground, 2 inches of nominal diameters, and steel pipe upper end (being well mouth of oil well) need install sealer additional with to being sealed between oil well and the oil pumping polish rod.
What sealer in the past and oil well were rigid links together, for guaranteeing its good seal, it is concentric in the vertical axis direction with oil well that oil pumping polish rod must keep, should not produce the deviation of horizontal level and the angle of inclination deviation of vertical axis direction, but this is difficult to reach, because huge oil pumper is difficult to reach so high positioning accuracy, even if reached, oil pumper is in working long hours, because vibrations still can cause producing between oil pumping polish rod and the oil well deviation of position; Because the left and right sides eccentric wear of oil pumping polish rod motion also can cause well head poorly sealed.
Summary of the invention
The purpose of this utility model provides a kind of oil pumping polish rod levelling sealer, position between itself and the oil well can be adjusted arbitrarily in scope of design, make the seal box of device keep good concentric with oil pumping polish rod, can guarantee the excellent sealing between seal box and the oil pumping polish rod, under the situation of position decentraction between oil pumping polish rod and the oil well, still can guarantee excellent sealing between the two, thoroughly solve the sealing difficult problem between oil pumping polish rod and the oil well.
For achieving the above object, the utility model is taked following design scheme:
A kind ofly be used for the device that the oil exploitation system seals well mouth of oil well, it includes:
One is used for the connection base that is connected with oil well, connects base and has flange and go up the central area and be interior concave spherical;
The spherical flange dish that is evagination sphere shape below one, this evagination sphere shape with connect base on the corresponding coupling of indent spherical shape;
One bottom periphery has the seal box that connects platform, piles up mutually for one group that dress is inserted and put by upper and lower nylon supporting positive cover in the seal box and closes sealed packing;
One locking flange;
The flange that connects base is fixedlyed connected with the spherical flange dish, and connection platform and spherical flange dish that the locking flange is pushed down the seal box periphery pass through bolt.
One inside and outside sealing shroud that all is sphere is arranged between described connection base and spherical flange dish; Described locking flange and spherical flange dish are gripped with sealing ring.
The utility model has the advantages that: sealing effectiveness is good; Applied widely, can both make seal box and oil pumping polish rod keep concentric under the situation of or decentraction concentric, and then guarantee excellent sealing between the two at oil pumping polish rod and oil well, just accomplished the excellent sealing between oil pumping polish rod and the oil well.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the adjustment principle schematic of the utility model oil pumping polish rod levelling sealer
The specific embodiment
Consult shown in Figure 1ly, the utility model oil pumping polish rod levelling sealer constitutes by connecting base 1, spherical flange dish 3, locking flange 5 and seal box 7 from bottom to up. Connection base 1,3 on spherical flange dish insert and put the sealing shroud 2 of sphere; Spherical flange dish 3,5 of flange of locking insert and put parallel sealing circle 4.
The lower end that the utility model is used for the device that the oil exploitation system seals well mouth of oil well is a connection base 1 that has flange, and connecting the base bottom is 2 inches sealed tube screw threads, can be tightly connected with oil well.Connect base top and be flange shape, the upper surface central area is interior concave spherical.
Be evagination sphere shape below the described spherical flange dish 3, this evagination sphere shape with connect base on the corresponding coupling of indent spherical shape.
Connecting on the base 1 upper flange periphery has 6 via holes, passes bolt from via hole, is connected with top spherical flange dish 3.Connect the sealing shroud 2 that a sphere is arranged between base and the spherical flange dish, the sealing shroud 2 of sphere is made by soft copper plate, and it guarantees to connect base and spherical flange dish excellent sealing.The spherical flange dish can be along the vertical axis direction, universal swing in scope of design.Tighten the set bolt of flange periphery, can make the fixing and excellent sealing at any point between the two.
Described seal box 7 belows are that bottom periphery has the sealed compartment 701 that connects platform 7011, sealed compartment 701 tops buckle packing and compress female 702, sealed compartment is built-in with one group of a group of being inserted and put by upper and lower nylon supporting positive cover 9,6 and piles up the sealed packing 8 that closes mutually, supporting positive cover with pass wherein the oil pumping polish rod precision movingly, its oil pumping polish rod to moving linearly plays centralizing function, piles up the packing that closes mutually for one group and seals.Packing compresses female 702 by packing clamping sleeve 10 compacting sealed packings and the seal box of fastening simultaneously.A nylon supporting positive cover respectively is equipped with in seal box top and bottom.Be the packing clamping sleeve on the packing, packing compresses female the pressure thereon, turns the dish newspaper and compresses mother, can adjust the sealing elasticity.
A planar seal ring 4 is arranged above the spherical flange dish 3, and it is made by withstand voltage asbestos packing sheet; It on it seal box 7 that sealed packing is housed.Seal box can move freely in scope of design by along continuous straight runs on the spherical flange dish.Relative position deviation between oil pumping polish rod and the oil well has determined the relative position between seal box and the spherical flange dish.Be enclosed within locking flange 5 above the seal box and push down the connection platform 7011 of seal box periphery, tighten the flange set bolt, can at an arbitrary position with seal box and the spherical flange dish be fixing and excellent sealing.
In the utility model oil pumping polish rod levelling sealer, the seal box of packing is housed, the connection base that is connected with oil well, separate, both are tightly connected together by planar seal ring, ball face sealing cover, therefore, can do the adjustment of horizontal level and vertical bank angle between the two.If oil pumping polish rod and oil well decentraction through adjusting, can make oil pumping polish rod and seal box concentric, therefore, guaranteed good seal between oil well and the oil pumping polish rod.
By above design, realized under the situation of oil pumping polish rod and oil well decentraction, still keeping good sealing.Its key is that the utility model can make seal box and oil pumping polish rod keep concentric, and then has guaranteed excellent sealing between the two, has just accomplished the excellent sealing between oil pumping polish rod and the oil well.
What Fig. 2 was represented is the scheme of installation under the situation of oil pumping polish rod 11 and oil well decentraction (all there is deviation at horizontal level and angle of inclination).
If in long oil pumping work, variation has taken place in the relative position between oil pumping polish rod and the oil well, has produced skew, at this moment, can unclamp the bolt on the flange easily, all parts of oil pumping polish rod levelling sealer, will move on to automatically new, the tram.Retorque starts oil pumper, recovers normal oil pumping work.
