Description
Technical field
The present invention relates to a kind of oil and offer winning apparatus, particularly relate to a kind of universal adjustment quick-replaceable packing temporary guide base
Root box.
Background technology
In oil exploitation industry, packing box is critically important parts, and Main Function is between polished rod and oil pipe
Seal, prevent liquid from overflowing.At present, a lot of oil wells are distributed in wild environment, due to oil pumper stream time
General the longest, the replacing of packing also becomes the groundwork of oil well management, but constantly the wearing and tearing and compress aging and fill out of packing
Material cavity space is narrow and small, and the replacing making packing is abnormal difficult, brings inconvenience to on-the-spot operation and maintenance.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art to provide a kind of simple and practical, it is simple to quick-replaceable
The universal adjustment quick-replaceable packing wellhead packing box of packing.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of universal adjustment quick-replaceable packing temporary guide base
Root box, including packing box housing, tooth bar, gearcase, packing, packing pressure cap, packing pressure pad, valve member, eccentric ball head, bias
Clip and ball pressure cap；Described packing box enclosure interior lower end is provided with tooth bar；Described tooth bar and the tooth being positioned at packing box housing side
Gear in wheel box is connected；Described tooth bar upper end connects packing；Described packing top is fixed by packing pressure cap；Described packing
And it is provided with packing pressure pad between packing pressure cap；Described packing box housing lower end is connected with eccentric ball head by valve member；Described
Eccentric ball head lower end is fixed by eccentric clip；Described eccentric clip is additionally provided with ball pressure cap with the junction of eccentric ball head.
Preferably, it is provided with nylon washer between described packing pressure cap and packing pressure pad.
Preferably, O type cushion rubber it is provided with between described eccentric ball head and valve member.
Preferably, it is provided with several O type cushion rubbers between described eccentric ball head and eccentric clip.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that the present invention program's
Wellhead packing box, its simple in construction, in-site installation is laborsaving, can quickly be replaced packing and packing pad safeguarding, with
Time can also do certain angle deflection adjust, meet reality use demand, there is higher practical value.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further.
Accompanying drawing 1 is the structural representation of the present invention.
Wherein: 1, packing box housing；2, tooth bar；3, gearcase；4, packing；5, packing pressure cap；6, packing pressure pad；7, valve
Assembly；8, eccentric ball head；9, eccentric clip；10, ball pressure cap；11, nylon washer；12, O type cushion rubber.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
One of the present invention universal adjustment quick-replaceable packing wellhead packing box as shown in Figure 1, including packing
Box housing 1, tooth bar 2, gearcase 3, packing 4, packing pressure cap 5, packing pressure pad 6, valve member 7, eccentric ball head 8, eccentric clip 9
With ball pressure cap 10；Described packing box housing 1 interior lower end is provided with tooth bar 2；Described tooth bar 2 be positioned at packing box housing 1 side
Gear in gearcase 3 is connected；Described tooth bar 2 upper end connects packing 4；Described packing 4 top is fixed by packing pressure cap 5；
It is provided with packing pressure pad 6 between described packing 4 and packing pressure cap 5；Described packing box housing 1 lower end is by valve member 7 and bias
Bulb 8 is connected；Described eccentric ball head 8 lower end is fixed by eccentric clip 9；Described eccentric clip 9 and the junction of eccentric ball head 8
It is additionally provided with ball pressure cap 10；It is provided with nylon washer 11 between described packing pressure cap 5 and packing pressure pad 6；Described eccentric ball head 8 and valve
O type cushion rubber 12 it is provided with between assembly 7；It is provided with several O type cushion rubbers 12 between described eccentric ball head 8 and eccentric clip 9.
In actually used, after the wellhead packing box of the present invention is connected on well head, sucker rod institute is to can on center
To do following adjustment: the adjustment at 15 degree of inclinations angle can be carried out by eccentric ball head, and eccentric ball head and bias can also be passed through
Hoop can adjust the bias of 0 to 18mm；When packing changed by needs, utilize the gear in gearcase that tooth bar is up moved
Dynamic, thus the packing pressure cap on packing is extruded, then packing is replaced can and rack structure quick-replaceable packing and
Packing pad.
Further, packing pad is for further protection plate mat.
The wellhead packing box of the present invention, its simple in construction, in-site installation is laborsaving, can be quickly to packing and packing pad
Being replaced safeguarding, the deflection that simultaneously can also do certain angle adjusts, and meets the use demand of reality, has higher practicality
It is worth.
Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employings
The technical scheme that equivalents or equivalence are replaced and formed, within the scope of all falling within rights protection of the present invention.
