Abstract
The utility model discloses a metal seal of a tubing hanger. Sealing prominences with a V-shaped section are arranged on the outer circumferential wall of the main metal body (1) of the seal at interval. The seal has the following characteristics: both end surfaces of the main metal body of the seal are hermetical pyramidal surfaces (3); and each hermetical pyramidal surface (3) is angled at 23 degrees plus or minus 30 minutes. On one hand, the main metal body of the seal has the advantages of aging resistance, corrosion resistance, low temperature tolerance, long service life, and the like., thus ensuring the safety and reliability of wellhead operation, and on the other hand, the pyramidal surfaces of the ends of the main metal body enlarge sealing surfaces and enhance bearing pressure, thus effectively protecting the safety of wellhead equipment and personnel.
Description
Technical field
The utility model relates to seal, is specifically related to a kind of tubing hanger metal seal.
Background technology
At present, the domestic nonmetal sealing straight tube of tubing hanger sealing widespread usage is hung, aspect defectives such as that nonmetal sealing exists is anti-aging, anticorrosive, low temperature resistant, application life, the safety of well head and the reliability of long-term work can not get guaranteeing, the employing round metal pillar sealing that also has, but sealing surface is little, and bearing pressure is little, contact surface is little, if main body or seal have very small defective will make seal failure.
Summary of the invention
The purpose of this utility model is: a kind of tubing hanger metal seal is provided, the sealing part is the metal conical surface seal, overcome the defective of aspects such as nonmetal sealing is anti-aging, anticorrosive, low temperature resistant, application life, improve the reliability of well head safe and long-term work, prolong well head application life, increase sealing surface on the other hand, strengthen bearing pressure.
Technical solution of the present utility model is: establish the sealing projection that the cross section is the V font at interval on the outer circle wall of the metal master of seal, it is characterized in that: the both ends of the surface of the metal master of seal are the conical surface.
In the tubing hanger metal seal of the present utility model, sealing cone is 23 ° ± 30 '.
Metal seal of the present utility model; on the one hand metal master is superior at aspects such as anti-aging, anticorrosive, low temperature resistant, application lifes; guarantee the safety and the reliability of well head work; the conical surface of metal master end has strengthened sealing surface on the other hand; strengthen bearing pressure, effectively protected wellhead equipment and personal security.
Description of drawings
Fig. 1 is the utility model structure sectional view.
Fig. 2 is the I-I enlarged drawing of Fig. 1.
Among the figure: 1. metal master, the sealing of 2.V font projection, 3. sealing cone.
The specific embodiment
As shown in Figure 1, 2, establish the sealing projection 2 that the cross section is the V font at interval on the outer circle wall of the metal master 1 of seal, it is characterized in that: the both ends of the surface of the metal master 1 of seal are sealing cone 3.
In the tubing hanger metal seal of the present utility model, sealing cone 3 is 23 ° ± 30 '.
Claims (2)
1. tubing hanger metal seal is established the sealing projection (2) that the cross section is the V font at interval on the outer circle wall of the metal master (1) of seal, it is characterized in that: the both ends of the surface of the metal master of seal (1) are sealing cone (3).
2. tubing hanger metal seal according to claim 1 is characterized in that: sealing cone (3) is 23 ° ± 30 '.
