Description
Technical field
This utility model relates in a kind of oil-field oil pumper well head production tree, for seal polished rod associated component, tool
It it is a kind of Novel oil well bush type packing_seal device for body.
Background technology
Aborning, rubber packing and polished rod are after friction after a while, and packing can because of abrasion not for rod-pumped well
Energy sealing wellhead, causes crude oil leakage.
Owing to oil well production tree is chronically at field, variations in temperature, alternate load and set become all to wellhead tree tree product
Raw tension, causes the inclination of wellhead packing box, makes well head misalign with polished rod, cause oil well mouth sealer sealed packing eccentric wear
Damaging aggravation, service life shortens, thus causes sealed packing to change frequently, and time serious, sealed packing lost efficacy and causes well head oil gas
Water leaks, and pollutes environment.
Use the method changing packing to be difficult to the wellhead tree tree packing tilted at present to take out, not only add worker's labor
Fatigue resistance, rate when also affecting operating efficiency and drive a well.
Summary of the invention
The purpose of this utility model be aiming at prior art exist drawbacks described above, it is provided that a kind of Novel oil well lining
Formula packing_seal device.
This utility model is realized by following technical proposals:
Novel oil well bush type packing_seal device, including: body, primary seal body, secondary seal body, two grades of packings, linings
Set, one-level packing, adjusting nut, packing gland, adjusting rod, polished rod, seal groove, groove；Its Novel oil well bush type packing is close
Envelope device body is crosswise cylindrical structure, and centre has one in step-like through hole, and top is provided with the external screw thread connecting adjusting nut,
Middle and lower part is symmetrical is provided with one group of secondary seal body, and equipped with two grades of packings in secondary seal body, top is provided with cylindrically
Primary seal body, in primary seal body, wall is provided with female thread, and the external screw thread being provided with lining matches.
Cylindrically, the diameter circular hole slightly larger than light shank diameter is arranged its lining at bottom, and sleeve lower surface is provided with one
The circular seal groove in road, top has four symmetrical grooves, and one-level packing is dosed between polished rod and lining.
Its adjusting nut is cylinder hollow-core construction, and the hexahedron that adjusting nut top is provided with welds an adjusting rod, internal
Equipped with in circular cone shape packing gland, packing gland compresses one-level packing.
The beneficial effects of the utility model are: compared with tradition packing sealer, devise threaded lining,
Change in the operation of sealed packing, easy, quick, safe and reliable, alleviate the labor intensity of operator, improve rate when recovering the oil
With rate when driving a well, there is good promotional value.
