Abstract
The utility model relates to a deviation-regulating packing box moving with a polish rod, which is applied in an oil extraction well-head of an oil field. A seal packing is arranged in the seal packing box, a packing cover presses the upper part of the seal packing, a seal packing pressure cap is arranged on the top of the seal packing box, an annular flange is sleeved on the outer wall of the cylindrical seal packing box; a support frame is fixed on the lower end face of the flange, the lower end of the support frame is fixed on a well head connecting flange; and the lower end of the seal packing box is sleeved with a corrugated pipe, the upper end of the corrugated pipe is fixed on the outer wall of the seal packing box, and the lower end of the corrugated pipe is fixed on the well head connecting flange. The utility model has the advantages of being capable of preventing a well head packing seal from being eccentrically worn, being adapted to to different rod oil extraction well heads, ensuring the safe operation of the well head packing sea system, improving the packing utilization ratio, reducing the leaking, enhancing the operation runtime of a pumping unit, and lowering the labor intensity.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and well head packing box in the bar oil recovery process is particularly arranged, and is a kind of packing box that can swing the energy automatic deflection adjusting with polished rod.
Background technology
At present, in the daily oil recovery production run in oil field, because when oil pumper polished rod eye wire rope drive polished rod pumps, polished rod waves phenomenon, movement locus is uncertain, friction between polished rod and the packing occurs uncertain, and well head sealed packing eccentric wear takes place, and causes sealing failure, well head leakage of oil, contaminated environment.Simultaneously frequent change the packing employee amount of labour big, influence ordinary production.In order to prevent the packing eccentric wear, need seek a kind ofly can adapt to the uncertain packing_seal device of oil pumper polished rod eye wire rope movement locus, prevent that effectively the eccentric wear phenomenon from appearring in packing.
The utility model content
The purpose of this utility model is: provide a kind of and move the tuningout packing box with polished rod, can effectively seal well head, and wave with oil pumper polished rod eye bottom polished rod, adapt to polished rod compound movement mode, solve well head sealed packing eccentric wear problem.It is uncertain to overcome the polished rod movement locus, causes the deficiency of packing eccentric wear influence production, contaminated environment.
The technical solution adopted in the utility model is: move the tuningout packing box with polished rod, mainly be made up of sealed packing pressure cap, packing gland, sealed packing box, flange, bellows, bracing frame and well head adpting flange.In the sealed packing box sealed packing is arranged, packing gland is pressed in the top of sealed packing, at the top of sealed packing box the sealed packing pressure cap is arranged, and rotatory sealing packing pressure cap can compress sealed packing.It is characterized in that: on the outer wall of cylinder bodily form sealed packing box, be with annular flange; Lower surface at flange is fixed with bracing frame, and the lower end of bracing frame is fixed on the well head adpting flange; Lower end at the sealed packing box is with bellows, and the upper end of bellows is fixed on the outer wall of sealed packing box, and the lower end of bellows is fixed on the well head adpting flange.
Distance between described annular flange center bore inner wall and the sealed packing outer box wall is between 2～10 millimeters.
Described bellows is a metal bellows, the upper end of bellows be welded on the sealed packing outer box wall around; The lower end of bellows is welded on the well head adpting flange upper surface.
Described flange lower surface is fluted, and is fluted in well head adpting flange lower surface, and the upper end of bracing frame is fixed in the groove of flange lower surface; The lower end of bracing frame is fixed in the groove of well head adpting flange upper surface.
On the outer wall of bracing frame, be welded with handle.
The operating principle of tuningout packing box is moved in summary with polished rod.Consult Fig. 1.Polished rod 1 passes sealed packing pressure cap 2, packing gland 3, sealed packing box 4, bellows 7 and well head adpting flange 10.Sealed packing in the sealed packing box 4 plays sealing function.During oil extraction operation, polished rod 1 pumps.Metal bellows 7 is fixed between sealed packing box 4 and the well head adpting flange 10, can make the crude oil that flow out sealed packing box 4 bottoms obtain sealing; In addition, when swing took place polished rod 1, along with the swing sealed packing box 4 of polished rod 1 is swung simultaneously, metal bellows 7 was with 4 swings of sealed packing box.Promptly adjust the angle of sealed packing box 4 automatically, it is vertical that packing_seal face and polished rod 1 are remained, and prevents the packing eccentric wear.
The beneficial effects of the utility model: the utility model moves the tuningout packing box with polished rod, can prevent well head packing_seal eccentric wear.Be adapted to the different bar production wellheads that have, guarantee the safe operation of well head packing sealing system, improve the packing utilization rate, reduce the generation of evaporating, emitting, dripping or leaking of liquid or gas phenomenon, rate when improving the oil pumper operation, reduce labour intensity.
