Description
Technical field
The utility model belongs to petroleum pipeline seal nipple field, specially a kind of metal for boll-weevil hanger end
Sealing ring and sealing device.
Background technology
In API6A（American Petroleum Institute (API), American Petroleum Institute）In standard, adopted for important
Oil or gas production wellhead, require that providing one kind is reliably tightly connected in installation exercise, between carrier and carrier.
For general well head, rubber seal is used mostly between carrier and carrier, but, rubber seal can not make for a long time
With long-term use occurs and follow the string that rubber seal can not be used in low temperature and high temperature, and low temperature occurs crisp aging
Change, high temperature occurs softening.
For the low temperature for less than -60 DEG C, the high temperature for more than 350 DEG C, for the important well such as the gas well containing H2S
Mouthful, it is accomplished by between carrier and carrier using expensive metal sealing, time, temperature that metal sealing will not typically be used
Degree and Korrosionsmedium influence, and the pressure outwardly and inwardly born currently used for the metal seal of tubing hanger end part seal is
Inconsistent, so in well head installation and debugging, cannot be judged in terms of the reliability of detection metal sealing, and it is this
Seal is single use, and install needs specific purpose tool with dismounting, to being provided with certain requirement.As shown in Figure 1.
Utility model content
The purpose of this utility model is exactly a kind of simple structure, yielding, good sealing effect and reusable is used for
The metal o-ring and sealing device of boll-weevil hanger end.

Face；The bottom surface of the upper support ring is inclined-plane, and the inclined-plane is contacted and angled difference with the drift angle of quoit body；The lower support
The top surface of ring is inclined-plane, and the inclined-plane is contacted and angled difference with the base angle of quoit body.
Compared with prior art, the utility model have simple structure, small volume, it is yielding and carrier between be metal
Seal, sealing reliability is good, can be used for the advantage of corrosive environment;Meanwhile, stress deformation is elastic deformation, reusable, right
Carrier is not injured, being capable of reduces cost；Beneficial effect is specific as follows：
1. metal o-ring Main Function is to provide and is sealed between keeping metal, so the metal o-ring cannot be only used for
In the field of API6A, may be alternatively used for other fields for needing metal to metal seal.
2. metal o-ring need not provide particular channel as API gasket rings and can be sealed, so simple structure,
It is easy to processing with manufacture.
3. the metal o-ring that metal o-ring plays same purpose with other compares, and volume is smaller, thus required space is more
It is small.
4. its simple structure of metal o-ring, can exchange each other, install and do not need specific purpose tool with dismounting, be easy to dress
Match somebody with somebody, saved the installation and debugging time, downtime is reduced to bottom line.
5. stress discharging slot is had in the cylindrical and inner circle of metal o-ring, so when being stressed, be more easily deformed, this
Sample avoids the need for increasing sealing of the bigger bolt torque to promote metal o-ring, meets API6A specifications and recommends answering for bolt
With.
6. special deformation groove is had in the cylindrical and inner circle of metal o-ring, and the deformation groove can play regulation compensation and carry
The scale error of body diametric(al) and short transverse, thus can meet installation requirements with particulate metal sealing ring.
7. many lower than the material hardness that seal carrier is used of the material hardness that is used by metal o-ring,
And the special construction of metal o-ring, so when in use, the sealing surface of seal carrier will not be destroyed.
Even if 8. under tension force, bending, compression and harsh operating condition, also need not periodically retorque and nut.
9. metal o-ring itself is not limited by size when in use, so the metal of all size size can be made into
Sealing ring.
10. metal o-ring is used, the support strength reduction for being sealed will not be made.
11. metal o-rings will not be limited by API6A flange bolt holes and be influenceed the design space of itself, that is
Particulate metal sealing ring very little in design itself.
12. metal o-rings can be designed to bear 20000Psi operating pressures at normal temperatures.
13. metal o-rings can select carbon steel, low-alloy steel, 300 series stainless steels and corrosion-resisant alloy material manufacture, institute
More a wide range of field can be used for particulate metal sealing ring, be particularly used to hydrogen sulfide, carbon dioxide corrosion working condition, accord with
Close the code requirements of API6A and NACE MR 0175.
14. metal o-rings are metals to metal seal, so can be used for less than -60 DEG C of low temperature and be used for 350
High temperature more than DEG C.
15. reliabilities that sealing is not interfered with the case of pressure oscillation.
16. can be reused repeatedly and without more renew.

Specific embodiment
The utility model is described further below in conjunction with accompanying drawing.
Embodiment 1
A kind of metal o-ring for boll-weevil hanger end, including quoit body 1, the longitudinal direction of quoit body are cut
Face assumes diamond in shape, and the inwall of quoit body 1 is provided with the first stress discharging slot 3.1 and annular first of annular successively from top to bottom
Deformation groove 4.1；The outer wall of quoit body is provided with the second stress discharging slot 3.2 and annular second of annular successively from bottom to top
Deformation groove 4.2；The section of stress discharging slot is triangular in shape, and the section for deforming groove is in circular arc.
Embodiment 2
Referring to Fig. 5, a kind of sealing device being made up of the metal o-ring for being used for boll-weevil hanger end in embodiment 1,
Including upper support ring 5, lower support ring 6 and metal o-ring, upper support ring 5, lower support ring 6 are arranged in metal o-ring
Top surface and bottom surface；The bottom surface of upper support ring 5 is inclined-plane, and the inclined-plane is contacted and angled difference with the drift angle of metal body 1；Lower branch
The top surface of pushing out ring 6 is inclined-plane, and the inclined-plane is contacted with the base angle of quoit body 1 and angled differs from 8.
Operation principle is as follows：
As shown in Figure 5, the section of metal o-ring body assumes diamond in shape, and two by the use of diamond-shaped cross-section are diagonal as metal pair
The contact point (i.e. contact point 7 in figure) of metal sealing, i.e., two diagonally contact with first vector 9 and Second support 10 respectively；Together
When, power is preferentially passed into quoit using the differential seat angle between upper support ring 5, lower support ring 6 and the contact surface of quoit body 1
The contact point of body 1, due to the difference of stress point, at contact point preferential stress and start deformation, with the increase puted forth effort, contact point
The power at place is also increasing, and the deformation at contact point is more and more abundant, so as to form metal sealing and sealing property is also more next
It is more reliable.As shown in Figure 4, due to the presence of stress discharging slot, so as to ensure that the power that metal o-ring body is born is ordered into
Distribution, the deformation for ensureing quoit body 1 is the plastic deformation that metal o-ring is avoided in regime of elastic deformation.Such as
Shown in Fig. 4, due to deforming the presence of groove, the scale error of compensation Carrier diameters direction and short transverse can be adjusted, thus
Installation requirements can be met with a special metal o-ring.
For those skilled in the art, on the premise of the utility model principle is not departed from, having can
Some improvements and modifications can be made to specific size, or partial structurtes, these improvements and modifications also should be regarded as the utility model
Protection domain.
