Abstract

The utility model relates to a graphite strengthening ring, which relates to the field of the flange seal, and is characterized in that a ring-shaped structure is formed by winding a graphite plate, a metal wire is also arranged inside the ring-shaped structure, the turn quantity of the metal wire is 3 turns to 5 turns, the metal wire is made of any one of copper, nickel or stainless steel. The graphite strengthening ring has a good self-lubricating effect and good compression rebound resilience, improves the pressure resistance and the high temperature resistance, also can prevent the medium from corroding a gasket, strengthens the anti-corrosion performance of the graphite strengthening ring, is convenient to install and disassemble, is difficult to be damaged, prolongs fifty times and even one hundred times of the service life of the gasket, and effectively improves the leak-proof capacity of a sealing connecting piece.

Description

A kind of graphite stiffening ring
Technical field
The utility model relates to a kind of gasket ring that is used for the flange seal field, a kind of specifically graphite stiffening ring.
Background technique
Gasket ring is of a great variety on the market, and wherein nonmetal and semimetallic material is most widely used, nonmetal quality softness, corrosion-resistant, low price, but heatproof and withstand voltage properties are poor, be used for more normal temperature and middle temperature in, the flange seal of low pressure vessel or pipeline; Semimetal (claiming metal composite again), though nonmetallic material have advantages such as good ductility, compressibility and bolt load ability are low, its major defect is that lubrication effect is poor, and rebound elasticity is poor, is not suitable for the high pressure-temperature occasion, and working life is short.
The model utility content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of graphite stiffening ring is provided, and has good self-lubricating function, anticorrosive property, and the good compression rebound elasticity, and high temperature resistant, is convenient to installation, dismounting, not fragile.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: a kind of graphite stiffening ring, by the graphite cake winding loop configuration that forms is set, and in this annular component, also be provided with wire, the number of turns wiry is the 3-5 circle.
The utility model, described material wiry are any one in copper, nickel or the stainless steel.
Beneficial effect is: a kind of graphite stiffening ring of the utility model has good self-lubricating function, the good compression rebound elasticity, improved withstand voltage, high temperature resistant, simultaneously can prevent that also medium from having strengthened the anticorrosive property of itself to the erosion of pad, be convenient to installation, dismounting, not fragile again, make the whole service life of pad prolong several 50 times even hundred times, effectively improved the leakage prevention capability of seal connector.
Description of drawings
Fig. 1 is a generalized section of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Mark is among the figure: 1, graphite cake, 2, wire
Embodiment
As shown in the figure, a kind of graphite stiffening ring, by graphite cake 1 winding the annular component that forms is set, in this annular component, also be provided with wire 2, the number of turns of wire 2 is the 3-5 circle, the material of wire 2 is any one in copper, nickel or the stainless steel, by setting up every excellent properties that wire significantly improves auxiliary graphite annulus; Graphite cake is by the extrusion modling of multilayer graphite paper, and the thickness of graphite cake can be set according to the size in flange seal space.
A kind of graphite stiffening ring of the utility model has good self-lubricating function, the good compression rebound elasticity, improved withstand voltage, high temperature resistant, simultaneously can prevent that also medium from having strengthened the anticorrosive property of itself to the erosion of pad, be convenient to installation, dismounting, not fragile again, make the whole service life of pad prolong several 50 times even hundred times, effectively improved the leakage prevention capability of seal connector.

Claims (2)
