Abstract
The utility model relates to the mechanical manufacturing field of a sealing piece, particularly relates to the structural improvement of a high temperature and high pressure resistant packing, etc. The utility model mainly solves the technical problems that the structure wire is made of graphite existing in the prior art so that the coagulating strength of the graphite is not enough, and neither of the resistance of the washing performance and the resistance of the extrusion performance are strong, etc. The utility model is formed by knitting, extruding or rolling a plurality of graphite structure wires (1), and a metal net layer (2) is knitted outside the structure wires. The utility model is characterized in that a plurality of metal reinforcement wires (3) are uniformly arranged inside the structure wires (1).
Description
Technical field
The utility model relates to a kind of Sealing of mechanical manufacturing field, especially relates to a kind of to the isostructural improvement of high temperature high voltage resistant packing.
Background technique
Present packing, constituting difference by material can be divided into: the rubber packing: though it is flexible good, lower-cost advantage, easily thorn leaks, and easily becomes fragile under the low temperature, and working life is short, and friction is big, big energy-consuming; Flexible graphite stuffing: its self-lubricating property is good, less energy intensive, however tensile strength is too little. and easily broken. be difficult for clamping, easily thorn leaks, and cost of production is higher.Common packing is unable to undergo washing away and push under the high pressure, the also temperature of suitable have more than is needed superelevation and the pressure of superelevation, and integrity is not good and the life-span is not long.Chinese patent discloses a kind of compound reinforced expanded graphite packing, and (publication number: CN 2175325Y), it is formed through extruding of (braiding) die orifice or rolling by the expanded graphite recombination line, and the outer surface of expanded graphite recombination line or packing is seized enhancement layer.But the structure line in the middle of the packing of this structure is made up of graphite fully, makes that its setting strength is not enough, and abrasion resistance and crush resistance are not strong.
Summary of the invention
The purpose of this utility model provides a kind of high temperature high voltage resistant packing, and it mainly is to solve existing in prior technology structure line to be made up of graphite fully, makes that its setting strength is not enough, the technical problem that abrasion resistance and crush resistance do not wait by force.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
High temperature high voltage resistant packing of the present utility model is formed through braiding, extruding or rolling by some graphite structure lines, and the outside of structure line is woven with the metal stratum reticulare, it is characterized in that described structure line inside is evenly equipped with some metals and strengthens silk.Structure line inside is evenly equipped with some metals enhancing silks and has strengthened abrasion resistance and crush resistance under high pressure, and thermal conductivity is good, and moulding and installation easily, and being kept perfectly property do not need end ring.And can be so that dimensionally stable is prevented gas and fluid leaks.
As preferably, described metal stratum reticulare and metal strengthen silk and are made by the severe nickel wire of high temperature resistant mattress.The nickel wire thermal conductivity is good, can keep the integrity of packing.Metal stratum reticulare and metal strengthen silk and also can be made by other high-temperature alloy silk.
Therefore, the utlity model has structure line inside and be evenly equipped with metal and strengthen silk, make characteristics such as its setting strength is stronger, and the outside is woven with the metal stratum reticulare, and abrasion resistance and crush resistance are better, and be rational in infrastructure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the high temperature high voltage resistant packing that this is routine, as Fig. 1, it is formed through braiding, extruding or rolling by graphite structure line 1, the outside of every root architecture line is woven with the metal layer 2 that the severe nickel wire of high temperature resistant mattress is made, the metal stratum reticulare be woven into by wire netted, structure line 1 inside is evenly equipped with metal that 5 severe nickel wires of high temperature resistant mattress make and strengthens the severe nickel screen structures of silk 3 outer braiding mattresses and strengthened abrasion resistance and crush resistance under high pressure, thermal conductivity is good, moulding and installation easily, and being kept perfectly property, do not need end ring.The structure linear dimension is stable, anti-gas and fluid leaks.Add special oiling agent in packing, self lubricity is good, and the life-span is longer.
Claims (2)
1. a high temperature high voltage resistant packing is formed through braiding, extruding or rolling by some graphite structure lines (1), and the outside of structure line is woven with metal stratum reticulare (2), it is characterized in that described structure line (1) inside is evenly equipped with some metals and strengthens silk (3).
2. high temperature high voltage resistant packing according to claim 1 is characterized in that described metal stratum reticulare (2) and metal strengthen silk (3) and made by the severe nickel wire of high temperature resistant mattress or other high-temperature alloy silk.
