Preferably, being provided with buffering ring between the sealing ring and locating ring.
By using above-mentioned technical proposal, the setting of buffering ring can fill space between sealing ring and locating ring, play
Further sealedly effect, simultaneously because sealing ring and locating ring are made comprising metal material, the setting of buffering ring can subtract
Few Relative friction between sealing ring and locating ring, makes to be less likely to occur Relative friction between sealing ring and locating ring to cause mill
Damage.
Preferably, the inner surface setting of the buffering ring has the groove being engaged with sealing ring peripheral shape, it is described slow
The outer surface for rushing ring is the arc sections being engaged with positioning ring inner surface.
By using above-mentioned technical proposal, the setting of groove and arc sections can play the effect of positioning, make sealing ring
Periphery is caught in groove, and arc sections are caught in the inwall of locating ring, makes the connection of buffering ring and sealing ring even closer, is difficult hair
Raw displacement.
Filled out preferably, the sealing outer shroud and sealing inner ring include between the second metal tape, second metal tape
Filled with non-metallic fillers.
By using above-mentioned technical proposal, the setting of filling non-metallic fillers can increase between sealing inner ring and sealing outer shroud
The modulus of elasticity of encryption envelope inner ring and sealing outer shroud, makes sealing inner ring and the both ends of the surface of sealing outer shroud when being squeezed, reduces close
The deformation quantity that ring axis direction occurs in envelope, because the modulus of elasticity of now sealing main ring is more than sealing outer shroud and sealing inner ring
Modulus of elasticity, can increase sealing outer shroud, sealing inner ring and sealing main ring between sealing effectiveness.
Preferably, second metal tape is in w shapes.
By using above-mentioned technical proposal, the resilience of w shape spirotallic gaskets is good, can further lifting coiling pad it is close
Seal effect.
Preferably, the both ends of the surface of the sealing ring are above the end face of locating ring.
By using above-mentioned technical proposal, in flange connection procedure, the bolt of two flanges of connection is connected to locating ring
Side, when the surface of flange abuts to the end face of locating ring, sealing ring can be compressed, and cause the first depressed part and turnover
Portion's Bending Deformation, sealing ring is radially extended, the sealing effectiveness of lifting coiling pad radial direction, and the axial direction of sealing ring can occur certain
Elastic deformation, making the axial direction of spirotallic gasket has preferable screen resilience.
Preferably, the non-metallic fillers are soft graphite.
By using above-mentioned technical proposal, soft graphite is one kind of non-cellulosic material, has excellent heat resistance and resistance to
It is cold；Interlayer under external force, easily produces slip, thus with lubricity, has preferable anti-attrition, coefficient of friction is small；
And with excellent chemical resistance；When there is radial run-out because manufacture, installation etc. have bias in spirotallic gasket, tool
There are enough floating performances, also can be closely sealed very well even if crackle occurs in graphite, so that ensure that note closes close, prevent leakage.
In summary, the utility model has the advantages that：
The spirotallic gasket makes its structure compacter by the setting for sealing inner ring, sealing outer shroud, is difficult loose；Pass through
The setting of buffer part and cavity, makes it have preferable resilience and restoring force, enhances the sealing effectiveness of spirotallic gasket；Will be soft
Property graphite be set to non-metallic fillers, also make the spirotallic gasket that there is preferable self lubricity, reduce spirotallic gasket to flange end
The abrasion in face.
