Abstract
The utility model provides a take sealed EGR gasket structure of gluing of high temperature, including the stainless steel gasket, the upper and lower surface of stainless steel gasket is located and is provided with the even coated high temperature resistant fluororubber of one deck around the sealing strip, and high temperature resistant fluororubber makes an organic whole structure with the stainless steel gasket. The utility model discloses overcome the not tight problem of sealing between the part connecting piece among the engine exhaust emission exhaust gas recirculation system, it is sealed tight to ensure to get into the EGR rate of engine in can making the EGR system, has simple structure, high temperature resistant, sealed good characteristics.
Description
Technical Field
The utility model belongs to the engine emission field, especially a seal gasket structure that is arranged in engine exhaust emission exhaust gas recirculation system part junction.
Background
The engine adopts EGR rate to control combustion to reduce emission, and joints of an EGR cooler, an EGR pipe and the like need to be sealed in the introduction process of high-temperature waste gas to prevent gas leakage.
An EGR system of the engine is connected with an engine exhaust system, is at a high temperature of more than 450 ℃ for a long time, requires a compact structure, generally adopts a stainless steel gasket for sealing, has higher requirements on the structure, the planeness and the size between an EGR pipe and a connecting piece, causes poor sealing and air leakage due to the accumulation of assembly tolerance, reduces the EGR rate and influences the exhaust.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a take sealed EGR gasket structure of gluing of high temperature to overcome the sealed not tight problem between the part connecting piece among the engine exhaust emission exhaust gas recirculation system.
In order to solve the technical problem, the utility model adopts the following technical proposal.
The EGR gasket structure with the high-temperature sealant comprises a stainless steel gasket, wherein a layer of high-temperature-resistant fluororubber which is uniformly coated is arranged on the periphery of a sealing strip on the upper surface and the lower surface of the stainless steel gasket, and the high-temperature-resistant fluororubber and the stainless steel gasket are manufactured into an integral structure.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses set up high temperature resistant fluororubber sealing layer on stainless steel gasket, its simple structure, it is small, sealed good and do not receive high temperature to influence, be applied to the reliability that the EGR system can improve engine EGR system, ensure that EGR gets into the volume of intake pipe, be favorable to maintaining EGR efficiency, reduce the emission.
Drawings
FIG. 1 is an exploded view of the present invention;
the figure is marked with: 1-stainless steel gasket and 2-high temperature resistant fluororubber.
Detailed Description
In order to make the objects and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is the utility model provides a take sealed EGR gasket structure of gluing of high temperature, including stainless steel gasket 1, the upper and lower surface of stainless steel gasket is located and is provided with the even coated high temperature resistant fluororubber 2 of one deck around the sealing strip, adopts current professional rubber coating technology with the even coating of high temperature resistant fluororubber 2 around the stainless steel gasket sealing strip, through drying, makes both fuse together. The thickness of the sealant of the high-temperature-resistant fluororubber can be adjusted according to the installation position and the flatness between the flanges.
According to the technical scheme, the stainless steel gasket 1 and the high-temperature-resistant fluororubber 2 are integrated, so that the stainless steel gasket is compact in structure, is favorable for installation, reduces labor cost, saves time and improves sealing performance.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
