Abstract
The utility model discloses a macromolecule fiber anti-corrosion flexible graphite packing which is mainly characterized in that: the macromolecule fiber anti-corrosion flexible graphite packing is provided with a packing body, and a molybdenum disulfide coating is coated outside the packing body; the packing body is formed by weaving macromolecule fiber anti-corrosion graphite lines penetrating through a knitting machine. By adopting the technical scheme, the molybdenum disulfide coating which has corrosion resistance and wear resistance is coated on the surface of the packing body, the packing surface and the surface of the sealing contact part are more corrosion-resisting, and the service life is prolonged. Compared with the prior art, the macromolecule fiber anti-corrosion flexible graphite packing has the advantages of being capable of being adaptive to the high-pressure-intensity high-line-speed working conditions, enhancing the corrosion-resisting capability and having long service life.
Description
Technical field
The utility model belongs to the stuffing box packing technical field, is specifically related to a kind of macromolecular fibre resistant to rust flexible graphite stuffing.
Background technique
Install and use in the process at rotary pump, reciprocating pump, valve seal filler, adopt cotton yarn to strengthen flexible graphite stuffing usually as first-selected stuffing box packing.The self lubricity of flexible graphite stuffing is good, corrosion resistance is strong because cotton yarn strengthens on the one hand, and fitting operation is easy, and flexible graphite stuffing is the environment protection type stuffing box packing that substitutes traditional asbestos packing on the other hand, and its cost performance is higher relatively.But because the restriction of vegetable fiber self character causes its heatproof, tensile strength, compressive strength to descend to some extent; Common in addition Expanded graphite is because himself sulfur-bearing oxidation affects; Cause leakage; Often find that not only flexible graphite stuffing damages in advance when upgrading Sealing, the corrosion phenomena that weight differs also takes place in the sealed member surface of its contact, the valve rod distortion of corroding; Need to change valve rod, cause certain economic loss.
Summary of the invention
For addressing the above problem, it is lower that the purpose of the utility model provides a kind of cost, high tenacity, and the resistant to rust effect is macromolecular fibre resistant to rust flexible graphite stuffing significantly.
For achieving the above object, the technological scheme that the utility model is taked is that said macromolecular fibre resistant to rust flexible graphite stuffing has the packing body, is coated with the molybdenum disulfide coating in the packing external; Braiding forms said packing body through the punching knitting machine by macromolecular fibre resistant to rust graphite line.
Because the utility model has been taked technique scheme, through being coated with the molybdenum disulfide coating in the packing surface, the molybdenum disulfide coating has corrosion resistance and wear resistance, can make the packing surface more corrosion-resistant with sealing surface, contact position, 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 anti-corrosion capability again, the advantage of long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1. packing body, 2. graphite line, 3. molybdenum disulfide coating.
Embodiment
Referring to Fig. 1, Fig. 2, the said macromolecular fibre resistant to rust of the utility model flexible graphite stuffing has packing body 1, is coated with molybdenum disulfide coating 3 in packing body 1 outside; Braiding forms said packing body through the punching knitting machine by macromolecular fibre resistant to rust graphite line 2; Expanded graphite line center comprises many 12tex macromolecule PAN reinforcing fibers; The Expanded graphite line prepares in the process and evenly adds high-purity super fine high activity metal zinc powder through the particulate powders adding set; Through punching braiding, give mold pressing after, handle through the molybdenum disulfide coating on the surface; Oven dry, final molding, packed products.
