Abstract

The utility model relates to the technical field of sealing packing, in particular to a kind of novel graphite packing. The novel graphite packing comprises a body, the body is formed by weaving polymer fiber graphite lines and metal wires in a mixing mode, and the metal wires are arranged in the shape of a cobweb on the cross section of the body. Compared with the prior art, the method that the polymer fiber graphite lines and metal wires are woven in the mixing mode is adopted for the novel graphite packing, and therefore the novel graphite packing has the advantages of being high in abrasion resistance and corrosion resistance; moreover, the metal wire layer of the cobweb structure strengthens the resilience of the packing and prolongs the service life of the packing; the novel graphite packing is suitable for a working environment with a high pressure and a large number of lines, effectively protects the mechanical usage safety of equipment and thus ensures the service life of the equipment.

Description

A kind of novel graphite packing

Technical field

The utility model relates to the stuffing box packing technical field, particularly a kind of novel graphite packing.

Background technique

In rotary pump, reciprocating pump, valve sealing filler are installed and used process, usually adopt cotton yarn to strengthen flexible graphite stuffing as first-selected stuffing box packing.Because good, the corrosion-resistant strong fitting operation of self lubricity of cotton yarn enhancing flexible graphite stuffing is convenient, flexible graphite stuffing is the environment protection type stuffing box packing that substitutes traditional asbestos packing on the other hand on the one hand, and its cost performance is relatively high.But, due to the restriction of vegetable fiber self character, cause its heatproof, tensile strength, compressive strength to descend to some extent; Common Expanded graphite is due to himself sulfur-bearing oxidation affects in addition, cause leakage, while upgrading Sealing, often find that not only flexible graphite stuffing damages in advance, the corrosion phenomena that weight differs also occurs in the sealed member surface of its contact, cause the valve rod distortion of corroding, cause larger economic loss.

The model utility content

The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of rational in infrastructure, compressive strength is high, the novel graphite packing of wear resistant corrosion resistant.

For achieving the above object, the utility model is by the following technical solutions:

A kind of novel graphite packing described in the utility model, comprise body, and described body is formed by macromolecular fibre graphite line and wire mixed weaving, and wire is the cobweb shape setting on the cross section of body.

Further, described wire is the severe nickel alloy wire of mattress.

Further, the external surface layer of described body is provided with the molybdenum disulfide coating.

The utility model beneficial effect is: compared with prior art, the utility model adopts macromolecular fibre graphite line and mixed weaving mode wiry, there are the corrosion resistant characteristics of high abrasion, and strengthened the resilience of packing by the metal wire layer of spider web structure, improved the working life of packing; The working environment that is applicable to the high line number of High Voltage, protect the machinery of equipment to use safety and life-span effectively.

Fig. 1 is overall structure schematic diagram of the present utility model.

In figure:

1, body; 2, wire; 3, molybdenum disulfide coating.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

A kind of novel graphite packing described in the utility model, comprise body 1, described body 1 is formed by macromolecular fibre graphite line and wire 2 mixed weavings, after graphite line has particulate powders to process and after wire 2 carries out repeatedly mixed weaving, wire 2 and graphite line form the Spaced setting that interweaves, and then make wire 2 form arachnoid structure on the cross section of body 1, and be coated with molybdenum disulfide coating 3 drying forming through mold pressing and body 1 surface after graphite line and wire 2 mixed weavings.

Preferred wire 2 adopts the severe nickel alloy wire of mattress, and then strengthens resilience of the present utility model.

Wire 2 in body 1 with the mixing the number of plies and can be increased according to the actual requirements of graphite line, the utility model preferably adopts three road wire 2 mixed weavings.

The above is only better embodiment of the present utility model, and the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and is included in the utility model patent claim.
