Abstract
The invention discloses a flat-face flange sealing gasket for an automotive exhaust system, which comprises an upper piece and a lower piece, which have the same shape and are overlapped and welded into a whole; through holes of the same size as the central hole of a flat-face flange of an exhaust pipe connector are formed in the middle of the upper piece and the lower piece; bosses are punched around the through holes on different sides of the upper piece and the lower piece respectively; the bosses form a sealing zone the flat-face flanges; furthermore, positioning pawl sheets are uniformly distributed on the outer circumference of the upper or lower piece of the sealing gasket. The structure of the gasket is simple and smartly designed and the punched bosses ensures the reliability of sealing, so the gasket better meet the requirements of increasingly strict laws and regulations; the uniformly distributed pawls make the installation of the gasket easy and positioning of the gasket accurate; and the up and down two layer structure helps to save soft material such as graphite or mica sheets used in the conventional gasket, and the gasket can be manufactured easily at low cost.
Description
Technical field
The present invention relates to automobile engine exhaust system, be specifically related to a kind of automobile exhaust system face-flange gasket seal.
Background technique
Along with the automobile making cost constantly rises, how rules increasingly stringents such as oil consumption, environmental protection reduce the automobile making cost, how to guarantee the sealing of vent systems, satisfy environmental requirement, are subjected to people and more and more pay attention to.It is reliable inadequately that vent systems face-flange gasket seal in the past has sealing, assembly precision is low, and adopt three-decker more, promptly two-layer up and down is to be flexible materials such as graphite or mica in the middle of the stainless steel sheets, whole gasket seal manufacturing process complexity causes the higher shortcomings of cost such as gasket seal material, manufacturing.
Summary of the invention
The object of the present invention is to provide a kind of automobile exhaust system face-flange gasket seal, its sealing simple in structure is ingenious and reliable, assembles accurate Location accuracy height, and material consumption is economized, gasket seal material and low cost of manufacture.
A kind of automobile exhaust system face-flange gasket seal, it is used to be installed between the exhaust fitting face-flange of vent systems.Described gasket seal comprise shape identical lay equal stress on folded be welded as a whole last slice and sheet down, last slice and following sheet centre have and exhaust fitting face-flange center hole through hole of the same size, described last slice and the opposing one side of following sheet along through hole on every side respectively punching press boss is arranged, last slice and the opposing one side of following sheet cooperate with the exhaust fitting face-flange respectively, boss by the surface forms sealing strip between face-flange, on last and following sheet also towards have with the exhaust fitting face-flange on the corresponding pilot hole in pilot hole position.This pad adopts double-layer structure impact briquetting up and down, saves flexible materials such as middle graphitic mica, and the cost of material is low, simple in structure.Product in the past mostly is three-decker, two-layer up and down is corrosion resistant plate, the middle flexible materials such as graphite or mica that adopt, three layers connection back cushion sheet center hole bound edge and three layers pressure and the card and higher of trying hard to keep to the bound edge quality requirement, graphite layer in the middle of in case the bound edge position is damaged is with ablated, cause vent systems gas leakage, lost efficacy in advance.And between face-flange, form sealing strip by boss, effectively guaranteed the sealing of vent systems flange connections.
Further, gasket seal last slice or down the periphery of sheet be evenly equipped with at least three ratchet that are used for exhaust fitting face-flange location, be used for and side plane flange location, improve assembly precision, guarantee the coaxality of pad and flange.Gasket seal does not in the past have the ratchet locating function, the low coaxality that can't guarantee gasket seal and flange of assembling back precision, assembling is fully by workman's hand-guided, often dress causes that partially the vent systems exhaust is not smooth, cause the engine consumption height, consequences such as it is serious to leak gas, this pad can address the above problem fully, and workman's assembling is had the effect of mistake proofing.
As seen, this pad is not only simple in structure, and is skillfully constructed.The punching press boss guarantees that sealing is reliable, efficiently solves the poorly sealed discharging that causes of vent systems problem not up to standard, better adapts to the Abgasgesetz of increasingly stringent; It is accurate that uniform ratchet makes this pad be easy to assembling and positioning; Adopt double-layer structure up and down to save flexible materials such as the graphite of conventional spacers or sheet mica, make simple, with low cost.

Fig. 4 is the schematic representation after the present invention and the face-flange assembling.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, this automobile exhaust system face-flange gasket seal by last slice 1 and following sheet 6 form, all adopt the 0.25mm stainless steel material, two plate shapes are identical lays equal stress on to fold and is welded as a whole.Have and the center hole of exhaust fitting flange 7 through hole 4 of the same size with following sheet 6 centres at last 1.At the periphery of last 1 and following sheet 6 also towards the pilot hole 5 corresponding with the pilot hole position on the exhaust fitting flange 7 arranged.The more important thing is, the opposing one side of last 1 and following sheet 6 around the through hole 4 respectively punching press boss 2 is arranged, last slice 1 cooperate with exhaust fitting flange 7 respectively with the opposing one side of following sheet 6, form sealing strip by the boss 2 on surface.In addition, last 1 or down the periphery of sheet 6 be evenly equipped with three ratchet 3 that are used for exhaust fitting flange 7 location.
Referring to Fig. 3, the profile of the boss 2 of last slice visible punching press of sectional view of 1 of gasket seal, following 6 boss 2 of gasket seal is identical therewith.
During manufacturing at first with gasket seal last slice 1 and under connect 6 impact briquettings, it is fixedly connected to connect spot welding up and down again.
Referring to Fig. 4, gasket seal is when entrucking, at first with the ratchet 3 of gasket seal and face-flange 7 location of a side wherein, face-flange 7 with a side is connected fastening with the face-flange 7 usefulness bolts of opposite side then, fixedly finish, the boss 2 of gasket seal both sides contacts with the surface of face-flange, forms sealing strip jointly, realizes the effect of reliable sealing.
