Abstract
The utility model provides an arc surface sealing ring of a hot oil extraction pipeline, which belongs to the field of machinery. The upper part of the sealing ring is provided with a clamping end, and the lower end is provided with an arc surface sealing part which is particularly an arc surface sealing wall. The arc surface sealing ring has the following characteristics: as the arc surface sealing ring is provided with the arc surface sealing wall, the connecting and sealing of the pipeline can be realized at different angles; moreover, the arc surface sealing ring has good sealing effect, can be repeatedly used, is convenient to inlay and install, has long service life and is suitable for being used in connection of the high-temperature/pressure pipeline.
Description
Technical field
The utility model provides mechanical field and is used for thermal recovery oil pipe line cambered surface seal ring.
Background technique
Before the utility model proposes, thermal recovery oil process need injects high temperature and high pressure steam down to oil well, is used for boosting oil production.And planar sealing pad is adopted in the connection between the pipeline usually, and fixes by slips.The shortcoming that exists is: because sealing gasket is a plane structure, so when an end pipeline run-off the straight, be difficult between the pipeline align, phenomenon therefore often leaks air.
Summary of the invention
In order to overcome the shortcoming that existing pipeline connects sealing gasket, the utility model provides thermal recovery oil pipe line cambered surface seal ring.The sealing ring is provided with globoidal structure by the seal ring outer side surface at tubulose, solves the sealing problem that the oblique bending pipeline connects.
The scheme that the utility model technical solution problem is adopted is: be provided with joint end on seal ring top, the bottom is provided with the cambered surface sealed department, and the cambered surface sealed department is the cambered surface sealed wall.
Good effect is: because the utility model cambered surface seal ring is provided with the cambered surface sealed wall, can realize from different perspectives that pipeline connects and sealing, and also good sealing effect, can reuse, be convenient to inlay installation, long service life.Suit in the High Temperature High Pressure pipeline connects, to use.
Description of drawings
Fig. 1 is the utility model seal ring three-dimensional structure diagram
Fig. 2 is the utility model seal ring broken section structural drawing
Fig. 3 is the utility model seal ring installment state figure
Among the figure, 1. seal ring, 1.1. joint end, 1.2. cambered surface sealed department, 1.21. cambered surface sealed wall, 2. connecting tube, 2.1. connecting head, 2.2. pore, 3. bail.
Embodiment
According to the figure, be provided with joint end 1.1 on seal ring 1 top, the bottom is provided with cambered surface sealed department 1.2, and the cambered surface sealed department is a cambered surface sealed wall 1.21.
The arc seal ring in use, be installed in two connecting tubes 2 that relatively are provided with connecting head 2.1 and pore 2.2 between, connect first end and have cambered surface seal ring assembly department, the other end is provided with the clamping annular distance, location when doing to install.After the cambered surface seal ring had been installed, the outer end of two ends pipeline connecting head was tightened by bail 3.
Cambered surface sealed department and pipe joint contacting part can be the conical surface.
When the pipeline generation several angle that is provided with cambered surface seal ring assembly department end tilts, because the curved surface of cambered surface sealed department and the deflection of cambered surface sealing assembly department surface of contact equally also can be played the effect of sealing.
The positive camber of cambered surface sealed wall is arc, curvecd surface type or sphere.
The advantage of the utility model arc surface sealing ring
1, an end of sealing ring is provided with joint end, is conducive to location when pipeline connects, and conveniently installs and uses;
2, because the outside of sealing ring is the curved surface with radian, thus can pipeline not point-blank the time sealing install;
3, because sealing ring has globoidal structure, thus can guarantee the curved surface of sealing and be located at sealing close contact set on the pipe joint, thereby, guaranteed the compactness that pipeline connects.
The utility model seal ring can be used in the High Temperature High Pressure pipeline connects widely.
Claims (2)
