Abstract
The utility model provides a sealed steel loop is connected to high temperature pipeline terminal surface, include that it makes up into the steel loop body to support steel ring 6 by radial support steel ring 1 and axial, the cover is equipped with axial compression conical ring 2 in proper order on the steel loop body, and sphere graphite sealing ring 3, soft metal gasket 4 and sphere graphite sealing ring 5. Its advantage lies in: combination steel loop body lateral extrusion needs with the product design of axial compression to the different requirements of bulk material hardness, the contact seal under the interior axial error of certain limit can be ensured in the design of sphere graphite annulus, and simultaneously, the pit can effectively be filled well to graphite material plasticity, reaches sealed purpose, multistage sealing ring is changeed the closed elasticity seal chamber of quick formation with gasket modular design messenger product and is reached the crush seal mesh.
Description
Technical field
The utility model relates to the sealing technique of heat note well High Temperature High Pressure pipeline joint.
Background technique
In oil well steam injection is produced, there is the spherical steel ring technology adopting hard rays sealing pipeline slips joint at present, and advantage is that spherical seal surface can contact sealing within the specific limits at axial error.But the Young's modulus of steel ring is high, the effective sealing problem after butt joint corrosion can not be answered.
Summary of the invention
The purpose of this utility model be to provide a kind of can be applicable to joint there is corrosion pit condition under High Temperature High Pressure sealer.
The utility model provides a kind of high temperature pipe end face to connect sealing steel ring, comprise and be combined into steel loop body by radial support steel ring 1 and axially support steel ring 6, steel loop body is set with axial compression conical ring 2 successively, sphere graphite-seal ring 3, metal gasket 4 and sphere graphite-seal ring 5.
Described radial support steel ring 1 and axially support steel ring 6 adopt unlike material different hardness to combine.
Described axial compression conical ring 2 adopts PTFE.
During use, on the steel loop body basis that unlike material different hardness is combined into, secondary is coordinated to have the carbon seal ring of sphere, the axial compression conical ring adding one-level metal gasket and be made up of PTFE forms, wherein, radial support steel ring closes knot steel by heat resisting and pressure resisting and makes so that it bears the lateral extrusion power under High Temperature High Pressure excessively, and axially support steel ring makes to bear axial compression by heatproof low carbon steel, radial support steel ring and axially support steel ring are combined into steel loop body with special process, add secondary carbon seal ring, metal gasket, axial compression conical ring is sleeved on steel loop body successively, form sealing steel ring of the present utility model.
The high temperature pipe end face that the utility model provides connects sealing steel ring, and its advantage is: combination steel loop body lateral extrusion and the product specification needs of axial compression to the different requirement of bulk material hardness; The design of sphere graphite annulus can guarantee the contact sealing in certain limit under axial error, and meanwhile, graphite material plasticity effectively can fill up pit well, reaches sealing purpose; Multistage dense seal ring shimming Combination Design makes the easier sealed elastic seal chamber that formed fast of product reach crush seal object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
