Description

A kind of double-packing incline lubricating type packing box
Technical field
The utility model belongs to petroleum machinery equipment technical field, relates to a kind of double-packing incline lubricating type packing box.
Background technology
Packing box is for sealing the well head moving seal apparatus of oil pipe and polished rod annular space, and it adopts multi-stage sealed, and good sealing effect is high pressure resistant.Simultaneously owing to being designed with universal joint adjustment bias and angle, be especially suitable for the oil well applications of well head deflection.
Existing packing box, it is eccentric adjustment amount artificially, be not inconsistent with actual polished rod offset, the easy like this packing that causes damages, polished rod favours packing box and cannot adjust, if polished rod tilt can make packing and packing box side pressurized, packing and packing box easily damaged, just need often to change packing, even change packing box.In addition, existing packing box mostly is single-deck root, will directly affect the carrying out of operation after breakage.
Utility model content
The purpose of this utility model is to provide a kind of double-packing incline lubricating type packing box, solves existing packing box and relies on artificial adjustment and the problem that cannot work after the deviation brought and the breakage of single-deck root.
The technical scheme that the utility model adopts is: a kind of double-packing incline lubricating type packing box, comprise the lower seat be connected with well head, lower seat is fixed with multi-directional ball by eccentric ball seat, multi-directional ball is fixed with one-level packing, one-level packing is provided with one-level packing gland, also comprise the secondary packing be fixed on secondary packing seat, secondary packing is fixed with secondary packing gland.
Feature of the present utility model is also:
Multi-directional ball is fixedly connected with lower seat with clamping plate by bolt.
Be provided with bunker between one-level packing and secondary packing, bunker is fixed on secondary packing seat by joint.
The both sides of bunker are respectively arranged with oil spill pipe and grease nipple.
The junction of multi-directional ball and ball seat is at least provided with O type circle a and O type circle b two O type circles.
The junction of lower seat and eccentric ball seat is provided with wound gasket.
Secondary packing gland is pressed with pressure cap.
Multi-directional ball and eccentric ball seat are fixed by sphere wedge.
The beneficial effects of the utility model are: a kind of double-packing incline lubricating type packing box of the utility model, and incline lubricating type packing box can along with the deflection of polished rod from Row sum-equal matrix; Be provided with bunker, when polished rod works, add that lubrication oil can reduce the broken wiping of polished rod and packing, extend the application life of packing; The sealing that is set to of double-packing provides dual fail-safe, after primary seal goes wrong, also has secondary seal can ensure normal work; Arranging of secondary seal grease nipple can play lubrication in time, prevents secondary seal from going wrong.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of double-packing incline lubricating type packing box of the utility model.
In figure, 1. polished rod, 2. pressure cap, 3. secondary packing gland, 4. secondary packing, 5. secondary packing seat, 6. joint, 7. oil spill pipe, 8. one-level packing gland, 9. one-level packing, 10. multi-directional ball, 11. sphere wedges, 12. eccentric ball seats, 13. bunkers, 14. wound gaskets, 15.O type circle a, 16.O type circle b, 17. bolts, 18. clamping plate, 19. times seats, 20. grease nipples.
Detailed description of the invention
