Abstract
A high-temperature resistant sealing gasket is an elastic annular metal piece with lower hardness, an annular arc-shaped bulge is arranged on one side of the gasket, and a corresponding annular arc-shaped groove is formed in the other side of the gasket. The utility model is used for mechanical parts's is sealed, especially the sealing of engine vent-pipe and booster junction, and during the use, the bulge is flattened, and is sealed effectual, can be high temperature resistant, can not be ageing, and during the maintenance, it is convenient to dismantle, and repeatedly usable is several, reduces and uses cost of maintenance, has overcome current expanded graphite composite sheet gasket easy ageing under the high temperature, and surface graphite drops, can not used repeatedly's defect after the dismantlement.
Description
Technical field
The utility model relates to a kind of gasket seal, especially for the refractory seal pad of engine exhaust system.
Background technique
The joint seal request height of engine exhaust pipe and pressurized machine, temperature is also very high.In the prior art, generally adopt with the expanded graphite composite sheet this joint is the ring-like gasket seal of a kind of surfacing of material, its deficiency is when gas temperature reaches more than 700 ℃, use a period of time, pad is easily aging, and surperficial graphite comes off, and can not reuse after the dismounting, therefore both influence sealing effect, also increased the cost that uses maintenance.
The model utility content
The utility model is intended to overcome the deficiencies in the prior art part, and a kind of good sealing effect is provided, and uses the low refractory seal pad of maintenance cost.
The technical solution of the utility model is: the refractory seal pad adopts metalwork flexible and that hardness is lower, is shaped as ring-likely, and a side of pad has the ring-type arc-shaped convex, and opposite side has corresponding ring-type circular groove.
The radius of above-mentioned arc-shaped convex is 1.5～2.5 times of spacer thickness, and height of projection is 1～2 times of spacer thickness; This pad is a circular shape, square ring type or other special-shaped ring-type.
Adopt above technological scheme, because pad is a metalwork flexible and that hardness is lower, there are circular groove and projection in both sides, and available 1Cr18Ni9Ti sheet stamping is made, and during use, convex portion is driven plain, and fits tightly good sealing effect with sealing surface; Under the high temperature, can not wear out and adhesion, during maintenance, convenient disassembly, several times reusable, reduce and use maintenance cost.
Description of drawings
Fig. 1 is the utility model embodiment sectional structure schematic representation;
Fig. 2 is a circular shape gasket seal schematic representation among the embodiment;
Fig. 3 is a square ring type gasket seal schematic representation among the embodiment.
Embodiment
As figure, present embodiment adopts the 1Cr18Ni9Ti sheet stamping to make, and thickness is 0.5mm.One side of pad has ring-type circular groove 2, and opposite side has corresponding ring-type arc-shaped convex 1, and the radius of projection is 1mm, and the height of projection is 0.8mm.Circular shape pad 3 and square ring type pad 4 or other special-shaped annular shim can be selected for use and definite concrete relative dimensions as required.
Claims (3)
1, a kind of refractory seal pad is shaped as ring-likely, it is characterized in that a side of pad has the ring-type arc-shaped convex, and opposite side has corresponding ring-type circular groove, and pad is a metalwork flexible and that hardness is lower.
2, by the described refractory seal pad of claim 1, the radius that it is characterized in that described arc-shaped convex is 1.5～2.5 times of spacer thickness, and height of projection is 1～2 times of spacer thickness.
3, by the described refractory seal pad of claim 1, it is characterized in that this pad is a circular shape, square ring type or other special-shaped ring-type.
