Abstract
The utility model discloses aramid fiber packing which comprises a packing body, and a polytetrafluoroethylene coating is coated on the outer side of the packing body. The packing body is formed by aramid fiber in an inertexture mode. The aramid fiber packing has the advantages of not only adapting to working condition environment of high intensity of pressure and high linear speed, but also strengthening anti-corrosion ability and being long in service life.
Description
Technical field
The utility model relates to a kind of packing.
Background technique
Install and use in the process at rotary pump, reciprocating pump, valve sealing filler, usually adopt cotton yarn to strengthen flexible aramid fiber packing as first-selected stuffing box packing.Because cotton yarn strengthens good, the corrosion-resistant strong fitting operation of the self lubricity of flexible aramid fiber packing conveniently, and flexible aramid fiber packing is the environment protection type stuffing box packing that substitutes traditional asbestos packing on the other hand, its cost performance is relatively high on the one hand.But because the restriction of vegetable fiber self character causes its heatproof, tensile strength, compressive strength to descend to some extent; Common Expanded graphite often finds that not only flexible aramid fiber packing damages in advance because himself sulfur-bearing oxidation affects causes leakage when upgrading Sealing in addition, the corrosion phenomena that weight differs also occurs in the sealed member surface of its releasing, the valve rod distortion of corroding needs valve rod, causes certain economic loss.
The model utility content
The utility model discloses a kind of cost lower, high strength, the resistant to rust effect is remarkable, the aramid fiber packing of good seal performance.
Aramid fiber packing of the present utility model comprises the packing body, is coated with the tetrafluoro coating in the packing external body.Described packing body is formed by the braiding of macromolecular fibre resistant to rust graphite line process punching.
Preferably, also comprise wire at described packing body.
The beneficial effects of the utility model are, owing to being coated with the tetrafluoro coating in the packing surface, the tetrafluoro coating has corrosion resistance, wear resistance, resistance to compression, tension, acidproof, alkaline-resisting, can make packing surface and sealing releasing surface, position more corrosion-resistant, increases the service life.Compared with prior art, the utlity model has the work condition environment that both adapts to High Voltage, high linear speed, strengthen again anti-corrosion capability, the advantage of long service life.
Description of drawings
Fig. 1 is the structural representation of aramid fiber packing of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and the specific embodiments, aramid fiber packing of the present utility model is further described.
As shown in Figure 1, aramid fiber packing of the present utility model comprises packing body 1, is coated with tetrafluoro coating 3 in packing body 1 outside.Braiding forms described packing body aramid fibre 2 through punching.Evenly add high-purity super fine high activity metal zinc powder by fine particle powder adding device in the aramid fibre preparation process, through punching braiding, give mold pressing after, process by the tetrafluoro coating on the surface, oven dry, final molding, packed products.
In optimal technical scheme, also comprise wire at described packing body, wire can be that packing tension, compression resistance are better.
What in addition, aramid fiber of the present utility model can be according to the demand of product need not be made into special-shaped packing.
In specific embodiment, the utility model can use widely in petrochemical industry, space flight, electric power, construction and installation, sealing etc.
More than described preferred embodiment of the present utility model, but it will be understood by those skilled in the art that under the prerequisite that does not break away from the utility model design philosophy, its various modification or combination are all included in the protection domain of claim of the present utility model.
Claims (2)
