Abstract
The utility model discloses a carbon fiber packing. The carbon fiber packing comprises a packing body. Coating is coated outside the packing body. The packing body is knitted by carbon fiber in a center penetrating mode. The carbon fiber packing has the advantages of being not only adaptive to a working condition environment high in pressure intensity and linear speed, but also capable of strengthening anti-corrosion capability, and 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 seal filler, adopt cotton yarn to strengthen flexible carbon fiber packing as first-selected stuffing box packing usually.Because cotton yarn strengthens good, the corrosion-resistant strong fitting operation of the self lubricity of flexible carbon fiber packing conveniently, and flexible carbon fiber packing is the environment protection type stuffing box packing that substitutes traditional asbestos packing on the other hand, its cost performance is higher relatively 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 is because himself sulfur-bearing oxidation affects in addition, cause leakage, often find that not only flexible carbon fiber packing damages in advance when upgrading Sealing, the corrosion phenomena that weight differs also takes place in the sealed member surface of its releasing, the valve rod distortion of corroding, need valve rod, cause certain economic loss.
The model utility content
It is lower to the utility model discloses a kind of cost, high strength, and the resistant to rust effect is the carbon fiber packing significantly.
Carbon fiber packing of the present utility model comprises the packing body, is provided with coating in the packing external body.Described packing body is formed by the braiding of carbon fiber process punching.
Preferably, described carbon fiber packing is high temperature resistant is 300 degree-350 degree.
The beneficial effects of the utility model are that owing to be provided with coating in the packing surface, coating has corrosion resistance and wear resistance, can make packing surface and sealing releasing surface, position more corrosion-resistant, increases the service life in addition, also comprises wire at the packing body.Make the resistance to compression of packing body, tension, resilience better, compared with prior art, the utlity model has the work condition environment that both adapts to High Voltage, high linear speed, strengthen anti-corrosion capability again, the advantage of long service life.
Description of drawings
Fig. 1 is the structural representation of carbon 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, carbon fiber packing of the present utility model is further described.
As shown in Figure 1, carbon fiber packing of the present utility model comprises packing body 1, is coated with platinic sulfide coating 3 in packing body 1 outside.Described packing body is formed by carbon fiber 2 process punching braidings.Evenly add high-purity super fine high activity metal zinc powder by the particulate powders adding set in the carbon fiber preparation process, through punching braiding, give mold pressing after, the logical coating that is provided with in surface is handled oven dry, final molding, packed products.
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 (1)
1. a carbon fiber packing comprises the packing body, is provided with coating in the packing external body; Braiding forms described packing body through punching by carbon fiber, it is characterized in that the packing body also comprises wire.
