Description
Technical field
The utility model relates to a kind of packing box universal adjusting device, belongs to petroleum industry technical field of oil production engineering.
Background technology
In recent years, along with the increase of service life of oil pumper, production tree, because of reasons such as well head transformation, job execution, rainwater immersions, cause underground utilities dislocation, distortion to pull production tree, cause production tree and oil pumping polish rod decentraction.There is horizontal departure in the axial line of part polished rod of pumping well and production tree, by existing anti-partial grinding packing set box, can proofread and correct.Due to distortion, pulling, cause production tree axial line and oil pumping polish rod axial line to produce the problem of certain angle, but can not solve by the Level tune of packing box the problem of polished rod eccentric wear.And two axial lines produce the well head eccentric wear problem at inclination angle just, caused the problems such as polished rod scuffing, sealed packing damage, well head pollution, cause polished rod, sealed packing to reduce application life, change frequent.Not only increased cost for oil production, rate while having affected oil well production, has increased operative employee's workload, also can environmental pollution.How to eliminate oil production equipment urgently to be resolved hurrily in the problem of well head generation inclination angle, axle center eccentric wear.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of packing box universal adjusting device.Use a kind of Universal packer box adjusting device, eliminate wellhead packing box and polished rod Jian inclination angle.Solve the scuffing of packing box to polished rod, and the wearing and tearing of polished rod to filler packing.
A universal adjusting device, gland for packing box is outer-hexagonal type, gland for packing box has centre bore; Male thread is arranged at packing box casing top, under packing box casing, connect spherical ball, upper jube is annulus, lower jube is positioned at the bottom of packing box casing, tail pipe bottom is male thread, connects spherical ball watt on tail pipe, and spherical ball watt inwall coordinates with spherical ball, upper flange is disk six hole flanges, upper flange and lower flange be connected packing box casing and afterbody; Upper flange coordinates for movable with packing box casing, and lower flange and afterbody are for being welded and fixed.
The utility model has the advantages that the adjustment by Universal packer box, extended the application life of oil pumping polish rod and packing filling, avoided the generation of well head environment pollution, reduced accounting for the well time of polished rod, sealed packing, the rate while having improved oil well production changed.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is that packing box of the present utility model partly cuts open structural representation.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of packing box universal adjusting device, gland for packing box 1 is outer-hexagonal type, gland for packing box 1 has centre bore; Male thread is arranged at packing box casing 3 tops, packing box casing connects spherical ball 83 times, upper jube 2 is annulus, lower jube 4 is positioned at the bottom of packing box casing 3, tail pipe 7 bottoms are male thread, connect spherical ball watts 9 on tail pipe 7, and spherical ball watt 9 inwalls coordinate with spherical ball 8, upper flange 5 is disk six hole flanges, upper flange 5 and lower flange 6 be connected packing box casing 3 and afterbody 7; Upper flange 5 coordinates for movable with packing box casing 3, and lower flange 6 and afterbody 7 are for being welded and fixed.
Embodiment 2: as shown in Figure 1, a kind of packing box universal adjusting device, is mainly comprised of gland for packing box, upper jube, packing box casing, lower jube, spherical ball, spherical ball watt, sealing ring, upper flange, lower flange, tail pipe.
During use, from oil-extractor polish-rod top, be inserted in, tail pipe has screw thread and the screwed connection of production tree rubber valve; Between the upper and lower jube in packing box casing, add airtight and watertight padding, play the sealing function between sealing oil-extractor polish-rod and production tree.
Gland for packing box center is porose to be connected with packing box casing, tail pipe, and gland for packing box and packing box casing, by screwed connection, in upper and lower jube position and packing box casing, work to support and compress packing filling.
Packing box lower box is provided with spherical ball, in spherical ball, is furnished with upper flange, upper flange coordinates with regulating ball activity, spherical ball coordinates with the spherical ball watt on tail pipe top, and ball plays angular adjustment and does use with watt being connected, and relies on the sealing ring in spherical ball watt to realize sealing between spherical ball and spherical ball watt, spherical ball watt top is welded with lower flange, lower flange is connected with upper flange, fixedly spherical ball and spherical ball watt, and spherical ball watt bottom screw thread is connected with production tree rubber valve.
Be applied to the rod-pumped well of oil pump rod and production tree axle center inclination.
Packing box universal adjusting device in use, first box root box universal adjusting device integral body is inserted in from sucker rod top, then tail pipe screw thread also production tree rubber valve is connected firm, first loosen after gland for packing box, loosen again and regulate mounting flange bolt between ball and adjusting ball watt, allow packing box the first half comprise gland for packing box, packing box casing, spherical ball, upper flange is in free adjustment state, then packing box is unloaded together with upper jube, be suspended on together on line suspending device, at packing box box house, lower jube top adds airtight and watertight padding, put down jube, first-class gland.
