Abstract
A kind of exhaust pipe seal gasket sheet, the annular resilient metalwork be formed in one, the upper and lower side of pad has one with upper annular arc-shaped convex, in the corresponding side in addition of side convex portion, is ring-type circular groove.The utility model is used for the sealing of the joint of engine exhaust pipe, structure is simple, easy to process, during use, upper and lower side has one to be pressed down with upper annular arc-shaped convex part, the sealing effect of upper and lower faces can be reached by the elastic force of annular metal, because metallic material can be high temperature resistant, can not be aging, and several times reusable, convenient disassembly, can reduce the user cost of producing and keeping in repair, easily aging under overcoming existing expanded graphite composite sheet etc. pad high temperature, can not reusable defect after dismounting.
Description
Technical field
The utility model relates to a kind of gasket seal, especially for the high-temperature resistant sealing pad of engine exhaust system.
Background technique
The joint seal request of engine exhaust pipe and pressurized machine is high, and temperature is also very high.In prior art, the general Bian in this joint is the ring seal pad of a kind of surfacing of material in order to expanded graphite composite sheet, and its deficiency is when gas temperature reaches 700 ° of more than C, use a period of time, pad is easily aging, and surperficial graphite comes off, and can not reuse after dismounting; Prior art has single side face protruding, therefore both affects sealing effect, also increases the cost of use and maintenance.
Model utility content
The utility model is intended to overcome the deficiencies in the prior art part, provides a kind of good sealing effect, and structure is simple, production, the high-temperature resistant sealing pad that use technology cost is low.
The exhaust pipe seal gasket sheet of technology of the present utility model, comprise exhaust port and fixed hole, there is at least one annular projection the upper and lower side of the periphery of described pad exhaust port, and be ring-type circular groove in the corresponding another downside of upside convex portion, described pad is that elastic metallic is one-body molded.
1 to 2 times of the radius of above-mentioned annular projection to be pad height of projection be spacer thickness thickness;
This pad is circular shape, square ring type or other special-shaped ring-type.
The above technological scheme of Bian, due to pad be flexible and metalwork, there is arc-shaped convex both sides, and during use, convex portion is pressed, and fits tightly with sealing surface, good sealing effect; Under high temperature, can not aging and adhesion, during maintenance, convenient disassembly, can repeatedly use, and because being formed in one, structure is simple, produces, use technology becomes low.
Accompanying drawing explanation
Fig. 1 is a kind of exhaust pipe seal gasket sheet schematic diagram.
Fig. 2 is the utility model embodiment sectional structure schematic diagram.
Embodiment
As figure, the sheet stamping of the present embodiment Bian elastic metallic is made, and thickness is 0.35mm to 0.55.Pad comprises exhaust port 2 and fixed hole 4, and wherein there is at least one annular projection 3 the upper and lower side of the periphery of exhaust port 2, and be ring-type circular groove 5 in the corresponding another downside of upside convex portion, pad 1 can be selected as required and determine concrete relative dimensions.
Claims (3)
1. an exhaust pipe seal gasket sheet, comprise exhaust port (2) and fixed hole (4), it is characterized in that there is more than one annular projection (3) the upper and lower side of the periphery of described pad exhaust port (2), be ring-type circular groove (5) at the corresponding opposite side of side convex portion, described pad is that elastic metallic is one-body molded.
2., by a kind of exhaust pipe seal gasket sheet according to claim 1, it is characterized in that the height of described arc-shaped convex (3) is 1 to 2 times of spacer thickness.
3., by a kind of exhaust pipe seal gasket sheet according to claim 1, it is characterized in that annular projection (3) on the upper and lower side of this pad is for several.
