Description
Technical field
This utility model relates to sealing device technical field, is a kind of metallic packing ring for radial seal.
Background technology
Xinjiang viscous crude oil exploitation is main based on thermal recovery technology exploitation, and its wellhead assembly used in thermal recovery technology needs tool
Standby can the ability of continuous firing under the operating mode of High Temperature High Pressure for a long time.At present, the tubing head of wellhead assembly seals with hanger
Main based on rubber seal, and industry is with the highest high temperature bearing 300 DEG C of resistant to elevated temperatures rubber, and new
Boundary oil field uses the temperature high-quality steam up to 337 DEG C to recover the oil, and therefore, rubber seal can not meet long-time at height
The requirement worked under temperature high pressure operating mode, thus, adversely affects thickened oil recovery.
Summary of the invention
This utility model provides a kind of metallic packing ring for radial seal, overcome above-mentioned prior art no
Foot, can not meeting that it can effectively solve that existing rubber seal exists in actual use is long-time in High Temperature High Pressure work
The problem of the requirement worked under condition.
The technical solution of the utility model is realized by following measures: a kind of metal sealing for radial seal
Ring, including metal ring body, is provided with in outside lower skewed epicone table top interior with in outward from top to bottom in the outside of metal ring body
Outer cone table top skewed under in upper, in becket body, the inner cone table top parallel with outer cone table top, interior frustum are arranged at the top of side
The upper end in face is connected with the upper end of epicone table top, and the lower end of epicone table top is connected with the upper end of outer cone table top, and inner cone table top is with outer
Frustum face is all vertical with epicone table top.
Further optimization and/or improvements to above-mentioned utility model technical scheme are presented herein below:
The lower inside of above-mentioned metal ring body is provided with linking frustum face, and linking frustum face is interior outside lower skewed.
The lower outside of above-mentioned metal ring body is provided with the lower frustum face being connected with outer cone table top, lower frustum face be interior under outside upper
Skewed.
This utility model reasonable and compact in structure, easy to use, its in use, the setting of metal ring body can be expired
The requirement that the foot length time works under high temperature and high pressure condition, establishes strong basis for thickened oil recovery, the outer frustum being parallel to each other
The face setting all vertical with inner cone table top and outer cone table top with inner cone table top and epicone table top can extend of the present utility model
Service life.
Accompanying drawing explanation
Accompanying drawing 1 is that the master of this utility model most preferred embodiment regards half section structural representation.
It is metal ring body that coding in accompanying drawing is respectively as follows: 1, and 2 is epicone table top, and 3 is outer cone table top, and 4 is inner cone table top, 5
For lower frustum face, 6 is linking frustum face.
Detailed description of the invention
This utility model is not limited by following embodiment, can come with practical situation according to the technical solution of the utility model
Determine specific embodiment.
In this utility model, for the ease of describing, the description of the relative position relation of each parts is all according to description
The Butut mode of accompanying drawing 1 is described, such as: the position relationship of forward and backward, upper and lower, left and right etc. is based on Figure of description 1
Butut direction determine.
Below in conjunction with embodiment and accompanying drawing, this utility model is further described:
As shown in Figure 1, this metallic packing ring being used for radial seal includes metal ring body 1, in the outside of metal ring body 1
Be provided with from top to bottom in interior outside lower skewed epicone table top 2 and in outside upper interior under skewed outer cone table top 3, at becket
The inner cone table top 4 parallel with outer cone table top 3 arranged at the top inside body 1, the upper end phase of the upper end of inner cone table top 4 and epicone table top 2
Even, the lower end of epicone table top 2 is connected with the upper end of outer cone table top 3, and inner cone table top 4 and outer cone table top 3 all hang down with epicone table top 2
Directly.The setting of metal ring body 1 disclosure satisfy that the requirement worked under high temperature and high pressure condition for a long time, establishes effectively for thickened oil recovery
Basis.It addition, the outer cone table top 3 being parallel to each other and inner cone table top 4 and epicone table top 2 all with inner cone table top 4 and outer frustum
The vertical setting in face 3 can outside frustum face 3 radial force time, outer cone table top 3 by epicone table top 2 by power conduction to interior frustum
Face 4, makes outer cone table top 3 and inner cone table top 4 and respective sealing surface reach to compress the state sealed；The outer cone table top being parallel to each other
3 and inner cone table top 4 and all vertical with inner cone table top 4 and outer cone table top 3 setting of epicone table top 2 can be in inner cone table top 4 footpath
When stress, power is conducted to outer cone table top 3 by inner cone table top 4 by epicone table top 2, makes outer cone table top 3 and inner cone table top 4 with each
From sealing surface reach to compress the state sealed, from without making this utility model expand deformation, extend this practicality newly
The service life of type.
According to actual needs the above-mentioned metallic packing ring for radial seal can be made further optimization and/or improvements:
As shown in Figure 1, the lower inside at metal ring body 1 be provided with linking frustum face 6, linking frustum face 6 in interior upper outside
Under skewed.Dismounting of the present utility model is easy in the setting in linking frustum face 6.
As shown in Figure 1, the lower outside at metal ring body 1 is provided with the lower frustum face 5 being connected with outer cone table top 3, lower cone
Table top 5 is in outside upper skewed under interior.Dismounting of the present utility model is easy in the setting in lower frustum face 5.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and optimal enforcement
Effect, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
