Description
Technical field
The utility model relates to airtight and watertight padding technical fields, and in particular to a kind of graphite packing.
Background technique
Packing is also named airtight and watertight padding, and the usually bar as made of relatively soft thread braiding, packing is filled in sealing
In cavity, to realize sealing.Airtight and watertight padding is to prevent liquid from revealing in leakage channel with fiber plugs such as fiber crops earliest, mainly
Axle envelope as axis body water lifting machinery.Since fill source is extensive, handling ease is cheap, and sealed reliable is easy to operate,
So using till today.Present packing is widely used in turning for centrifugal pump, compressor, vacuum pump, blender and propeller for vessels
Sealing, piston pump, reciprocating compressor, the reciprocating motion axle envelope of refrigeration machine and turn sealing of various valve rods etc..
Currently, graphite packing is a commonly used seed type in packing, it the advantage is that heat-conductive characteristic is preferable, but due to graphite
Graphite material itself used in packing is more fragile, so surface is easy to fall off in use, leads to graphite packing
Service life greatly shortens.
Utility model content
To solve the above-mentioned problems, the utility model discloses a kind of high mechanical strengths, the stone that tensile strength is high, the service life is long
Disc root.
In order to achieve the above object, the utility model adopts the following technical solution:
A kind of graphite packing, including basic core weave jacket layer with N layers of graphite, and the basis core is single or more and head
The composite stone line of ink marker, the N layers of graphite braiding jacket layer stacks gradually from inside to outside to be wrapped in outside basic core；The graphite weaves jacket layer
It is the graphite interdigitated interlock braiding structure layer as made of the braiding of several composite stone line of ink marker interdigitated interlocks；The composite stone line of ink marker includes
The soft graphite core of internal layer and the bond course being wrapped in outside soft graphite core are set；The bond course is by least two weights
The lamina reticularis of diamond shape hole is had made of folded braided wires braiding.
Further, the braided wires are wire, macromolecular fibre or glass fibre any one of them.
Further, the diameter of the braided wires is 0.05~0.12cm.
Further, the N is more than or equal to 0.
Further, the N is more than or equal to 2.
Further, the cross sectional shape of the graphite packing is rectangle, round or ellipse.
Compared with prior art, the utility model has the following beneficial effects: the graphite packing of the utility model, is by N layers of stone
Ink braiding jacket layer stacks gradually the solid being wrapped to form from inside to outside, due to for multilayered structure, so that the machine of the graphite packing
Tool intensity and tensile strength are higher, and graphite braiding jacket layer is woven by several composite stone lines of ink marker, the composite stone line of ink marker
Appearance is also wrapped on bond course, further enhances the mechanical strength and tensile strength of the graphite packing, and enhancement layer is with water chestnut
The reticular structure of shape hole is coated on the appearance of flexible graphite layer, and reducing graphite, surface large area falls off in use
A possibility that, so that the longer life expectancy of the graphite packing.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the front view of the composite stone line of ink marker of the utility model.
Description of symbols: 1 be basic core, 2 be graphite braiding jacket layer, 3 be the composite stone line of ink marker, 31 be soft graphite core,
32 be bond course.
Specific embodiment
The present invention will be further described for embodiment with reference to the accompanying drawing.
Referring to attached drawing 1, a kind of graphite packing, including basic core 1 and N layers of graphite weave jacket layer 2, and N is more than or equal to 0, preferably
Ground, N are more than or equal to 2.Basic core 1 is single or more and the composite stone line of ink marker of head, and N layers of graphite braiding jacket layer 2 are compiled using set
Mode stack gradually be wrapped in outside basic core 1 from inside to outside, the cross sectional shape for weaving the graphite packing of completion is rectangle, circle
Or ellipse.
Graphite braiding jacket layer 2 is the graphite interdigitated interlock braiding structure as made of the braiding of several composite stone line of ink marker interdigitated interlocks
Layer, so that graphite braiding 2 surface of jacket layer forms the pattern of several parallelogram.In order to further enhance the machine of graphite packing
Tool intensity and tensile strength, referring to attached drawing 2, the composite stone line of ink marker 3 includes that the soft graphite core 31 of internal layer is arranged in and is wrapped in soft
Property graphite core 31 outside bond course 32, soft graphite core 31 use prior art preparation, details are not described herein, it is preferable that soft
Property graphite core 31 shape be cuboid.Bond course 32 is to have diamond hole as made of at least two braided wires being overlapped braidings
The lamina reticularis in hole；Preferably, braided wires be wire, macromolecular fibre or glass fibre any one of them, it is further preferred that
The material of braided wires can be nickel alloy, copper, iron, polyester fiber, glass fibre any of them, and the diameter of braided wires is
The reticular density of 0.05~0.12cm, bond course 32 can also select according to demand.
The foregoing is merely the better embodiment of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, there may be the structural modifications that part is small in implementation process, if various changes or modifications to the utility model are not
The spirit and scope of the utility model are detached from, and are belonged within the scope of the claims and equivalents of the utility model, then originally
Utility model is also intended to encompass these modification and variations.
