Description
Technical field
The utility model relates to a kind of packing more particularly to a kind of fiber aramid fiber intertexture packings.
Background technique
In the prior art, the packing as sealing function has wider use scope, and packing is also named airtight and watertight padding, usually
It is woven by relatively soft thread, is filled in seal cavity by bar, to realize sealing, packing seal is earliest
It is to prevent liquid stream from leaking in leakage path with fiber plugs such as linen-cottons, is mainly used as the axle envelope of water lifting machinery, since filler comes
Source is extensive, handling ease, cheap, and sealed reliable is easy to operate, so continuing to use to gold, packing is widely used in petroleum neck
Centrifugal pump, compressor, vacuum pump, the seal airtight of driving shaft of blender and the piston pump in domain, reciprocating compressor, refrigeration machine it is past
The turn sealing etc. of axle envelope and various valve rods is moved again.Rotary pump, reciprocating pump, valve sealing filler install and use
In the process, it generallys use cotton yarn and increases flexible aramid fiber packing as airtight and watertight padding first, on the one hand since cotton yarn enhances flexible virtue
The self-lubrication of synthetic fibre packing is good, corrosion-resistant strong, easy for installation, and on the other hand, flexible aramid fiber packing is that substitution tradition is asbestos disk
The environment-friendly type airtight and watertight padding of root, cost performance is relatively high, but due to the limitation of plant fiber self character, cause its heatproof,
Tensile strength, compression strength are declined, in addition, existing packing is typically all that single strip of material is worked out, mechanical property
Although in some aspects preferably, in other aspects there is also deficiency, resilience is also poor.
Summary of the invention
Technical problem to be solved in the utility model be for above-mentioned state of the art and provide a kind of screen resilience compared with
Good fiber aramid fiber intertexture packing.
Technical solution adopted by the utility model to solve the above technical problems is as follows: the fiber aramid fiber intertexture packing, including
There is packing ontology, it is characterised in that: the packing ontology is intersected by aramid fiber and graphite fibre each 1/2 works out, described
There is elastic webbing, the thickness of the elastic webbing and the aramid fiber and the graphite fibre between aramid fiber and graphite fibre
The thickness ratio of the packing ontology of composition is 1:2~1:5.
In order to realize the wearability of elastic webbing, the outer surface of the elastic webbing is equipped with wearing layer, and the wearing layer is by carbon fiber
Winding weaves dimension in the shape of a spiral.
In order to improve the fire resistance of the fiber aramid fiber intertexture packing, the outer surface of the wearing layer is additionally provided with outer isolation
Layer, the outer separation layer are formed by mica tape coiling.
In order to realize that the screen resilience of elastic webbing, the elastic webbing intersect establishment by polytetrafluoroethylene band and nitrile rubber band
It forms, the thickness ratio of the polytetrafluoroethylene band and nitrile rubber band is 1:4~1:6.
Compared with prior art, the utility model has the advantage of the fiber aramid fiber intertexture packings by aramid fiber and graphite
Fiber each 1/2, which intersects, works out, and wherein aramid fiber has superhigh intensity, the high temperature resistant of the performance of acid and alkali-resistance and graphite fibre
And lubricity is strong, and has elastic webbing therebetween, so that the screen resilience of the fiber aramid fiber intertexture packing is preferable, has more
Strong compression strength.

Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
It as shown in figures 1-4, is the most preferred embodiment of the utility model.Fiber aramid fiber intertexture packing packet in the present embodiment
Packing ontology 1 is included, packing ontology 1 is worked out by aramid fiber 11 and the intersection of graphite fibre 12 each 1/2,11 He of aramid fiber
There is elastic webbing 3, the packing ontology that the thickness and aramid fiber 11 and graphite fibre 12 of elastic webbing 3 are constituted between graphite fibre 12
1 thickness ratio is 1:2~1:5, the fiber aramid fiber intertexture packing establishment intersected by aramid fiber 11 and graphite fibre 12 each 1/2 and
At, wherein aramid fiber 11 has superhigh intensity, and the high temperature resistant and lubricity of the performance of acid and alkali-resistance and graphite fibre 12 are strong, and
And there is therebetween elastic webbing 3, so that the screen resilience of the fiber aramid fiber intertexture packing is preferable, there is stronger compression strength.
In order to realize the wearability of elastic webbing 3, the outer surface of elastic webbing 3 is equipped with wearing layer 31, and wearing layer 31 is by carbon fiber
Winding weaves in the shape of a spiral, and wherein the outer surface of wearing layer 31 is additionally provided with outer separation layer 32, and outer separation layer 32 is preferably
It is formed by mica tape coiling, mica tape has preferable high temperature resistance and flame resistance, to improve fiber aramid fiber intertexture
The fire resistance of packing, while the screen resilience in order to realize elastic webbing 3, elastic webbing 3 is by polytetrafluoroethylene band 33 and nitrile rubber
The intersection of band 34 is worked out, and the thickness ratio of polytetrafluoroethylene band 33 and nitrile rubber band 34 is 1:4~1:6, preferably 1:5.
