Abstract

The utility model discloses a high-strength graphite gasket, relating to the field of flange sealing. The high-strength graphite gasket is ring-shaped and consists of a ring-shaped metal plate at a middle layer and graphite plates at outer layers of two sides, wherein the thickness of the metal plate is 1-3mm, and the metal plate is made of carbon steel or stainless steel. In the high-strength graphite gasket, the compression resilience is good, the strength is high, the pressure resistance and the high temperature resistance are improved, and the corrosion resistance is enhanced as media can be prevented from corroding the gasket; and the high-strength graphit gasket is convenient to install and disassemble, and is not easy to be damaged, so that the whole service life of the high-strength graphite gasket is prolonged by fifty times, even hundred times, and the anti-leakage capability of a sealing connecting piece is effectively improved.

Description

A kind of high-strength graphite pad
Technical field
The utility model relates to a kind of pad that is used for the flange seal field, a kind of specifically high-strength graphite pad.
Background technique
The kind of existing market Upper gasket is varied, is divided into nonmetal, semimetal and metallic shim three major types by the motif material of its structure; Nonmetallic gasket 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; Semi-metallic gasket (claiming the metal composite pad again), though nonmetallic material have advantages such as good ductility, compressibility and bolt load ability are low, its major defect is that intensity is not high, and rebound elasticity is poor, is not suitable for the high pressure-temperature occasion, and working life is short; Metallic shim, under critical operation conditions such as High Temperature High Pressure and loading cycle be frequent, but pad requires greatly because of pretightening force, easily causes the bolt flange distortion, causes leaking and causing environmental pollution and product loss.
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 high-strength graphite pad is provided, and has to be convenient to installation, dismounting, not fragile, high temperature resistant, high pressure, has good anticorrosive property and good compression rebound elasticity and high strength.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: a kind of high-strength graphite pad, ringwise, constitute by the outer field graphite cake of annular metal sheet and both sides in mesosphere, and the thickness of sheet metal is 1-3mm.
The utility model, the material of described sheet metal are carbon steel or stainless steel.
Beneficial effect is: a kind of high-strength graphite pad of the utility model has good compression rebound elasticity and high strength, 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 structural representation of the present utility model.
Fig. 2 is a generalized section of the present utility model.
Mark is among the figure: 1, graphite cake, 2, sheet metal
Embodiment
As shown in the figure, a kind of high-strength graphite pad, ringwise, the outer field graphite cake 1 of annular metal sheet 2 and both sides by the mesosphere constitutes, the thickness of sheet metal 2 is 1-3mm, and the material of sheet metal 2 is carbon steel or stainless steel, by setting up every excellent properties that sheet metal significantly improves auxiliary Graphite pad; 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.
The utlity model has good compression rebound elasticity and high strength, 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.
