Description
Technical field
The present invention relates to high pressure sealing vibration insulation structure more particularly to a kind of high pressures suitable between pressure vessels and pipes
Seal isolation mounting.
Background technique
Pressure vessel refers to filling gas or liquid, carries the Sealing Arrangement of certain pressure, and pressure vessel ontology has
Pipeline access apertures, pipeline access apertures is interior to be equipped with pipeline, passes through pipeline input and output gas or liquid.At the pipeline of pressure vessel
(pressure vessel ontology and pipe connection portion position) is typically provided with sealing, isolation mounting, on the one hand needs to high pressure in pressure vessel
Gas is sealed, and is on the other hand needed to carry out vibration isolation processing between pipeline and pressure vessel to Relative Vibration, is avoided or subtract
Influencing each other between the vibration of weak pressure vessel and pipe vibration.In current engineering practice, the sealing of high pressure gas
It is usually independent design with pipeline vibration isolation, and generallys use conventional seals circle when conventional seals, is easy the destruction being vibrated, it is difficult
To meet condition of high voltage.
Summary of the invention
Goal of the invention: to solve the problems of the prior art, the present invention provides a kind of compact-sized, integrated pressure
Container conduit seals isolation mounting.
Technical solution: pressure vessel conduit of the present invention seals isolation mounting, comprising:
The metallic inner for being sheathed on pipeline and being tightly connected with pipeline outer wall;
The metal outer ring connecting with pressure vessel ontology, the metal outer ring is outside the pipeline access apertures of pressure vessel ontology
Week arranges there is gap between metal outer ring and metallic inner;
The rubber cover of the annular between the metal outer ring and metallic inner on gap is covered on, is equipped with several in rubber cover
Carbon fiber line, the both ends of every carbon fiber line are connect with metallic inner with metal outer ring respectively.
It is preferred that the metallic inner is mutually welded with pipeline outer wall, the metal outer ring is mutually welded with pressure vessel ontology.
It is preferred that the longitudinal section of the rubber cover is U-shaped, U-shaped both ends are connect with metallic inner with metal outer ring respectively.
It is preferred that the carbon fiber line is U-shaped, You Duogen carbon fiber is knitted to form.
It is preferred that the rubber cover is tightly connected by sulfuration process and metal outer ring and metallic inner, and coat carbon fiber
Line.
For different pressure vessels, structural parameters of the invention can be configured according to its performance requirement, for
It is preferable to design when especially compressor housing internal and external pressure difference is 3.2 megapascal or so in the case that pressure vessel is compressor
Parameter is as follows: the metallic inner and metal outer ring use yield strength for the steel of 235~345 megapascal, rubber cover and metal
The contact surface of inner ring and metal outer ring carry out vulcanizing treatment, and treated vulcanization face, tensile strength be 3~4 megapascal.It is described
The elasticity modulus of carbon fiber bundle is 200000~300000 megapascal, and tensile strength is 3000~5000 megapascal.Adjacent two carbon fibers
The distance for tieing up line outer diameter circle is 0.5~1.5 millimeter.If carbon fiber line density design is too low, rubber cover will lead in two carbon fibers
The part tieed up between line is excessive, and for rubber cover in the case where internal and external pressure difference, quiet deformation is excessive, not only reduces the service life, it is also possible to
Lead to rubber failure;Carbon fiber line density design is excessively high, not only increases cost, there is also overstocked carbon fiber line carbon fiber
Cover is divided into inside and outside two parts, keeps its stress distribution uneven, reduces the service life.
The utility model has the advantages that
Two independent structures are used to realize corresponding sealing, vibration isolation function respectively sealing and vibration isolation in existing engineering practice
Can, and pressure vessel conduit of the invention seals isolation mounting, has plyability --- while meeting two mesh of vibration isolation and sealing
Mark, it is compact-sized.
The present invention is embedded in carbon fiber line in rubber cover, quiet under pressure vessel internal high pressure for limiting rubber cover
Deformation, while carbon fiber line bears most of stress as caused by high pressure, reduces the stress inside rubber, has rubber cover
There is longer service life.In addition carbon fiber line has little effect rubber block in rigidity axially and radially, the vibration isolation effect of rubber
Fruit it is unaffected (because carbon fiber line be designed to it is U-shaped, when metallic inner and metal outer ring mutually vibrate, carbon fiber line only
Radial bending or torsion can be generated.Again because carbon fiber line is very small in the elasticity modulus of its radial direction, and almost do not have
There is torsion stiffness.Therefore carbon fiber line is negligible to the stiffness effect of rubber block, and then does not influence the vibration isolating effect of rubber).If
Elastic support is added in rubber, then will affect the Static stiffness and dynamic stiffness of rubber, be degrading vibration isolating effect.
