Description
Technical field
It the utility model is related to hanger, and in particular to self-compensation sealed slips hanger.
Background technology
The slips hanger used at present, need to tighten bolt by high pulling torque to excite sealing ring when in use, reach
Sealing sleeve pipe requirement.
The content of the invention
The purpose of this utility model is：A kind of self-compensation sealed slips hanger is provided, self-compensation sealed mechanism is used for
Sealing sleeve pipe, conventional products are only needed to excite the half strength of moment of torsion, you can to realize good sealing effectiveness.
Technical solution of the present utility model is：Sleeve pipe is arranged on casing head body by hanger body and slip insert
On, it is characterized in that：Self-compensation sealed mechanism seals sleeve pipe is installed, described self-compensation sealed mechanism includes spiral shell in hanger body
Circle, inner support circle are supported in bolt, outer support circle, taper sealing circle, pressing plate and inner support circle, the top and bottom of taper sealing circle by outer
One pressing plate is installed respectively and is bolted.
Wherein, the taper face in interference oblique angle is designed with pressing plate.
Wherein, it is outer to support all to be designed with slant cutting edge on circle and inner support circle.
Wherein, tapered boss is designed at the internal-and external diameter of the top and bottom of taper sealing circle and is used for self-compensation sealed.
The utility model has the advantages that：
1st, the taper face in interference oblique angle is designed with pressing plate, supports circle and inner support circle to produce and slide laterally for outer；
2nd, it is outer to support circle and inner support circle to be all designed with slant cutting edge so that bracing ring is flexible, easy quilt after stress
Strut, prevent seal from being punctured by pressure；
3rd, tapered boss is designed at the internal-and external diameter of the top and bottom of taper sealing circle and is used for self-compensation sealed, formed after stress
One lip sealing ring, produce sealing function；
4th, when hanger carries pressure, pressure is acted on pressing plate, outer to support circle and inner support circle to taper sealing circle
Self compaction is produced, realizes hanger self-compensation sealed；
5th, taper sealing circle is designed to that interior collar extension carries taper boss, excites pressing plate by tightening bolt so that taper is convex
Table top deforms to form a lip-type seal ring, reaches sealing effectiveness.
6th, self-compensation sealed slips hanger of the present utility model carries compensation sealing ring, effectively avoids bolt from tightening torsion
The possibility of seal failure in the case of square deficiency, also for sealing ring, not breakdown offer is effective together under long-time pressure state
Ensure.
Brief description of the drawings
Fig. 1 is that self-compensation sealed slips hanger uses schematic diagram.
In figure：1 bolt, 2 support to enclose outside, 3 taper sealing circles, 4 pressing plates, 5 inner support circles, 6 hanger bodies, 7 slip inserts,
8 casing head bodies, 9 sleeve pipes.
Embodiment
As shown in figure 1, sleeve pipe 9 is arranged on casing head body 8 by hanger body 6 and slip insert 7, it is characterized in that：
Self-compensation sealed mechanism seals sleeve pipe 9 is installed, described self-compensation sealed mechanism includes bolt 1, outer support in hanger body 6
Circle 2, taper sealing circle 3, pressing plate 4 and inner support circle 5, the top and bottom of taper sealing circle 3 support that enclosing 2, inner support circle 5 divides by outer
A pressing plate 4 and it An Zhuan not fixed by bolt 1.
Wherein, the taper face in interference oblique angle is designed with pressing plate 4.
Wherein, it is outer to support all to be designed with slant cutting edge on circle 2 and inner support circle 5.
Wherein, tapered boss is designed at the internal-and external diameter of the top and bottom of taper sealing circle 3 and is used for self-compensation sealed.
During assembling, casing head body 8 is installed in place according to normal drilling well flow, and lower 9 sleeve pipes to projected depth and are cemented the well；Gu
After the completion of well, hanger assembly is installed on 9 sleeve pipes；Above carry 9 sleeve pipes（About 30 tons or so of lifting force）, by hanger assembly
The upper end of casing head body 8 is placed on, symmetrically tightens 1 bolt so that taper sealing circle 3 holds 9 sleeve pipes tightly；Slow release lifting force,
Slowly it is put into the inner chamber of casing head body 8 together with 9 sleeve pipes and hanger assembly；Subsequently held according to normal drilling technology
OK；When exciting sealing, bolt 1 is symmetrically tightened so that the pressing plate 4 of each 1 compresses to the direction of taper sealing circle 3 up and down, compressed
The longitudinal size of taper sealing circle 3 diminishes in journey（Thickness diminishes）Lateral dimension increases, and reaches outside diameter seal casing head body 8 and interior
Footpath sealing sleeve pipe 9；Pressing plate 4 supports circle 2 and inner support circle 5 to produce and slide laterally in taper face with outer simultaneously, outer to support 2 Hes of circle
It is softened, is fitted on the inwall of casing head body 8 and the outer wall of sleeve pipe 9 after the stress of inner support circle 5, after prevents seal to be pressurized
It is breakdown.
