Abstract
The invention provides an exhaust manifold sealing gasket. A sealing gasket body comprises a sealing gasket upper layer, a sealing gasket lower layer and a limiting layer. The limiting layer is located between the sealing gasket upper layer and the sealing gasket lower layer, and the sealing gasket upper layer, the sealing gasket lower layer and the limiting layer are welded into a whole. The sealing gasket body is provided with air flue holes corresponding to exhaust manifolds in position. The limiting layer is shorter than the sealing gasket upper layer and the sealing gasket lower layer in hole openings of the air flue holes; in other words, only the sealing gasket upper layer and the sealing gasket lower layer exist in the hole openings and make contact with each other in an attached mode, and the limiting layer is not exposed, so that it is ensured that the sealing gasket still has a certain sealing bar height due to the limiting layer when the hole opening edges are completely compressed, and sealing failure is prevented. The air flue holes in the whole sealing gasket body are partially separated through cut openings, so that sealing gasket tearing caused by hot creep of the exhaust manifolds is eliminated, and therefore the sealing gasket is prevented from being broken.
Description
Technical field
The invention belongs to Seal Design field, be specifically related to the sealing configuration of gas exhaust manifold.
Background technique
Gas exhaust manifold sealing gasket is the important sealing gasket of numbers of hot-side engine, and because sealing pad operating ambient temperature is high, gas exhaust manifold heat is wriggled large, therefore often occurs seal failure leakage problem.As shown in figs. 1 and ia, it is welded together by sealing gasket upper strata 1 and sealing gasket lower floor 2 and forms gas exhaust manifold gasket structure conventional at present, and the upper and lower are at gas port place punching press sealed muscle 11 and 21.Existing gas exhaust manifold gasket structure is simple, cost is low, for general naturally aspirated engine, the requirement of sealing can be reached, but along with engine booster technology, the application of in-cylinder direct injection technology, gas exhaust manifold heat load is more and more higher, adjoint hot creeping deformation is more and more serious, and this structure is difficult to the requirement meeting sealing, often occurs the faults such as sealed muscle wear out failure leaks gas, sealing gasket breaks, sealing gasket ablation.
Summary of the invention
For the high problem causing seal failure of thermal loads for engine exhaust manifold, the present invention proposes a kind of gas exhaust manifold sealing gasket, and quasi-solution is following technical problem certainly:
(1) the high sealing gasket ablation problem caused of delivery temperature;
(2) the sealing gasket sealed muscle wear failure problem that causes of gas exhaust manifold creeping deformation;
(3) the sealing gasket crack damage problem that causes of gas exhaust manifold creeping deformation.
For solving the problem, the present invention adopts following technological scheme;
A kind of gas exhaust manifold sealing gasket, sealing gasket main body comprises sealing gasket upper strata and sealing gasket lower floor, also comprise spacing layer in addition, spacing layer is between sealing gasket upper strata and sealing gasket lower floor, three layers are welded as a whole, sealing gasket main body is distributed with the air flue hole corresponding with gas exhaust manifold position, at the aperture place in air flue hole, spacing layer is shorter than sealing gasket upper strata and sealing gasket lower floor, namely sealing gasket upper strata and sealing gasket lower floor double-layer structure is only had at aperture place, two-layer directly contact laminating, spacing layer does not expose, to ensure that sealing gasket is when orifice edge is compacted completely, due to the existence of spacing layer, still certain sealed muscle height is had, avoid seal failure.And between each air flue hole of whole sealing gasket main body by otch local separately, to eliminate tearing sealing gasket when gas exhaust manifold heat is wriggled, thus it is damaged to solve sealing gasket.
Further, in the outside of sealing gasket upper strata and sealing gasket lower floor, there are sliding coating and sliding coating, solve high temperature lower seal pad ablation problem with this and alleviate the gas exhaust manifold heat sealing gasket caused of wriggling and tear.
The present invention has following obvious advantage:
(1) between sealing gasket upper strata and sealing gasket lower floor, spacing layer is increased, setting is not exposed at aperture place by spacing layer, certain height is formed in sealing gasket upper strata and sealing gasket lower floor, namely form sealed muscle, when to ensure that the orifice edge of sealing gasket is compacted completely, still have certain sealed muscle height.
(2) outside of sealing gasket upper strata and sealing gasket lower floor increases resistant to elevated temperatures sliding coating, solves high temperature lower seal pad ablation problem and alleviate the hot sealing gasket caused of wriggling of gas exhaust manifold to tear;
(3) cut between each air flue hole by otch, tearing sealing gasket when gas exhaust manifold heat is wriggled can be eliminated, thus it is damaged to solve sealing gasket.
Accompanying drawing explanation
Fig. 1 is gas exhaust manifold gasket structure schematic diagram conventional at present;
Figure 1A is the A-A sectional drawing of Fig. 1;
Fig. 2 is the structural representation of gas exhaust manifold sealing gasket of the present invention;
Fig. 2 A is the A-A sectional drawing of Fig. 1;
Fig. 3 is air discharging manifold flange face structural representation.
In figure: 1-sealing gasket upper strata, 2-sealing gasket lower floor, 3-solder joint, 4-mounting hole, 5-air flue hole, the spacing layer of 6-, 7-otch, 8-air discharging manifold flange, 11-sealed muscle, 21-sealed muscle, 12-sliding coating, 22-sliding coating.
Embodiment
Below in conjunction with accompanying drawing, structure of the present invention is described further:
See Fig. 2, be solve that supercharged direct-injection engine exhaust sealing pad is damaged, gas leakage, ablation problem, the gas exhaust manifold sealing gasket agent structure that the present invention proposes comprises sealing gasket upper strata 1, spot-welded together between sealing gasket lower floor 2 and 6, three layers, spacing layer.Sealing gasket main body is distributed with 4 the air flue holes 5 corresponding with gas exhaust manifold position.
Specifically see Fig. 2 A, spacing layer 6 is between sealing gasket upper strata 1 and sealing gasket lower floor 2, but close to each air flue hole 5 orifice position, spacing layer 6 is shorter than sealing gasket upper strata 1 and sealing gasket lower floor 2, namely just double-layer structure is only had at aperture place, sealing gasket upper strata 1 directly contacts laminating with sealing gasket lower floor 2, and spacing layer 6 does not expose
.like this due to thin near orifice edge, outwards then thicken due to intermediate finite position layer 6, when can ensure that sealing gasket is compacted completely, by thin to having certain rebound elasticity thicker than that position crossed, namely still have certain sealed muscle height.
Meanwhile, this sealing is paid somebody's debt and expected repayment later increases high temperature resistant sliding coating, and material is molybdenum disulfide.Specifically in the outside of sealing gasket upper strata 1 and sealing gasket lower floor 2, increase resistant to elevated temperatures sliding coating 12 and sliding coating 22, the wearing and tearing to sealing gasket during to reduce gas exhaust manifold hot creeping deformation.
See Fig. 3, to wriggle the tearing sealing gasket that may cause to tackle manifold further, on whole gasket structure, a part is cut by between each for manifold air flue hole 5, the position of otch 7 is corresponding with air discharging manifold flange 8 incision site, to eliminate tearing sealing gasket when gas exhaust manifold heat is wriggled, thus it is damaged to solve sealing gasket.
