Abstract
The utility model relates to a kind of packing, especially relates to a kind of pure graphite outsourcing nickel chrome wire braiding packing.Its packing mainly solved existing for prior art uses under higher temperature and pressure occasion, because the burning of inner reinforcing material and Bond is lost, product size stability, crush resistance are declined, creates the technical problem of the seal leakage of " run, drip, leak " etc.The utility model comprises pure graphite tape (1), described pure graphite tape (1) becomes stock to be woven into packing body (2), pure graphite tape appearance surface cover is composed of the severe nickel wire net (3) of mattress, the outer surface of pure graphite tape has the meshed grooves (4) that can embed the severe nickel wire net of mattress, the bottom of meshed grooves is communicated with some calendering chambeies (5), and the opening diameter in calendering chamber is less than its inside diameter.
Description
Technical field
The utility model relates to a kind of packing, especially relates to a kind of pure graphite outsourcing nickel chrome wire braiding packing.
Background technique
Along with developing rapidly of process of industrialization, harsher to the seal request of High Temperature High Pressure and oxide etch operating mode, flexible graphite stuffing is used widely due to the asbestos of the excellent replaced harmful human body of its heat resistance, but, because Expanded graphite line structure is loose, very easily washed away by medium fluid, and reinforcing material is cotton thread in it, the materials such as glass, use under higher temperature and pressure occasion, because the burning of inner reinforcing material and Bond is lost, make product size stability, crush resistance declines, create and " run, emit, drip, leak " seal leakage problem.
Model utility content
The utility model is to provide a kind of pure graphite outsourcing nickel chrome wire braiding packing, its packing mainly solved existing for prior art uses under higher temperature and pressure occasion, because the burning of inner reinforcing material and Bond is lost, product size stability, crush resistance are declined, creates the technical problem of the seal leakage of " run, drip, leak " etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Pure graphite outsourcing nickel chrome wire braiding packing of the present utility model, comprise pure graphite tape, described pure graphite tape becomes stock to be woven into packing body, pure graphite tape appearance surface cover is composed of the severe nickel wire net of mattress, the outer surface of pure graphite tape has the meshed grooves that can embed the severe nickel wire net of mattress, the bottom of meshed grooves is communicated with some calendering chambeies, and the opening diameter in calendering chamber is less than its inside diameter.Pure graphite tape of the present utility model adopts the large scale graphite of anti-oxidant treatment.Use high temperature to steam drainage technique desulfurization when high temperature puffing, adopt cyclone blanking, the myrmekite ink that the flat high temperature puffing of heap that roll-in platform gathers is good, do not add any reinforcing fiber and compound viscose glue, roll the Expanded graphite coiled material low fever's mistake, high strength, even density, then cut into flexible graphite belt, guarantee the characteristic such as Expanded graphite high-purity, high temperature low fever mistake.Then the severe nickel wire of coaxial knitting machine overcoat mattress is adopted to point flexible graphite belt cut; form the packing braided wire of the severe nickel wire weave mesh of crystal lattice type mattress; play the integrity strengthening and protect graphite tape, ensure that the abrasion resistance of the braiding every root strand of packing under high-temperature high-pressure medium.Use high speed and precision knitting machine, prismatic is from level to level adopted to intert superimposing braid technique, the severe nickel wire weave mesh of every root graphite tape crystal lattice type mattress is evenly distributed inside and outside braiding packing, and obtained final products have that decorative pattern is smooth, braiding gap is minimum, compactness is stronger.Guarantee the abrasion resistance, the crush resistance that weave packing, especially high temperature resistant more more outstanding than performance with pressure-bearing.
Meshed grooves of the present utility model is used for embedding mattress severe nickel wire net, thus the severe nickel wire net of braiding packing and mattress is had be combined better, prevent mattress severe nickel wire net protrusion packing outer surface.Arranging some calendering chambeies in the bottom of meshed grooves, making packing when using calendering, a part of pure graphite tape or the severe nickel wire net of mattress can enter in calendering chamber, thus can not excessively make knitting disc velamen flatten expansion, and sealing is better.
As preferably, described pure graphite tape be provided with calendering limit at the cavity place of the severe nickel wire net of mattress, the one end on calendering limit is connected on pure graphite tape, is bent outwardly in the middle part of the body on its calendering limit.Calendering limit and pure graphite tape leave gap, and make packing adaptability in use better, ductility is higher.
As preferably, the outer surface rolling of described mattress severe nickel wire net has multiple annular ridge, and annular ridge tilts to one end.Annular ridge is set, the severe nickel wire net of mattress can be made to be embedded in meshed grooves better, and mutually between be not easily shifted.
Therefore, the utility model has excellent temperature tolerance, scour resistance, crush resistance and good compression, rebound elasticity; Under the various harsh conditions such as high temperature, high pressure, oxide etch, its excellent sealing performance can be kept, meet the usage requirement of the harsh operating modes such as high temperature, high pressure and oxide etch completely, simple and reasonable for structure.

Component, position and numbering in figure: the severe nickel wire net 3 of pure graphite tape 1, packing body 2, mattress, meshed grooves 4, calendering chamber 5, calendering limit 6, annular ridge 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the pure graphite outsourcing nickel chrome wire braiding packing of this example, as Fig. 1, comprise pure graphite tape 1, pure graphite tape becomes stock to be woven into packing body 2, and as Fig. 2, pure graphite tape appearance surface cover is composed of the severe nickel wire net 3 of mattress, as Fig. 3, the outer surface of pure graphite tape has the meshed grooves 4 that can embed the severe nickel wire net of mattress, and the bottom of meshed grooves is communicated with some calendering chambeies 5, and the opening diameter in calendering chamber is less than its inside diameter.Pure graphite tape is provided with calendering limit 6 at the cavity place of the severe nickel wire net of mattress, the one end on calendering limit is connected on pure graphite tape, is bent outwardly in the middle part of the body on its calendering limit.The outer surface rolling of mattress severe nickel wire net has multiple annular ridge 7, and annular ridge tilts to one end.
During use, the utility model is encased in the places such as flange to be sealed.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
