A kind of exhaust pipe gasket, is set between exhaust pipe and engine cylinder cover, the exhaust pipe and the engine cylinder
Lid is bolted, comprising:
First single layer gasket and the second single layer gasket；
The first single layer gasket and the second single-layer pad on piece are correspondingly arranged on and are respectively facing the exhaust pipe and institute
The arc convex of the sealing surface of engine cylinder cover is stated, and forms cavity between the arc convex；
Limited block is additionally provided between the first single layer gasket and the second single layer gasket.
Preferably, the limited block is weldingly connected with the first single layer gasket and the second single layer gasket respectively.
Preferably, the first single layer gasket and the second single layer gasket are metal gasket.
Preferably, the limited block is made of single-layer metal thin plate.
Preferably, the height 1.2mm-1.3mm between described two arc convex.
Preferably, the first single layer gasket and the second single layer gasket with a thickness of 0.25mm-0.3mm.
Preferably, the limited block with a thickness of 0.05mm-0.1mm.
As can be seen from the above technical solutions, exhaust pipe gasket disclosed in the utility model, is set to exhaust pipe and hair
Between motivation cylinder cap, exhaust pipe and engine cylinder cover are bolted, comprising: the first single layer gasket and the second single layer gasket；
First single layer gasket and the second single-layer pad on piece are correspondingly arranged on the arc for being respectively facing the sealing surface of exhaust pipe and engine cylinder cover
Shape protrusion, and cavity is formed between arc convex；Limited block is additionally provided between first single layer gasket and the second bed course gasket.Row
Tracheae gasket is set between exhaust pipe and engine cylinder cover, is set to the arc of the first single layer gasket and the second single-layer pad on piece
The raised sealing face contact with exhaust pipe and engine cylinder cover respectively, in bolt the process of close-up tracheae and engine cylinder cover
In, firstly, the arc convex for being set to the first single-layer pad on piece is set to the second single-layer pad by the pressing force from exhaust pipe
The arc convex of on piece is by the pressing force covered from engine cylinder, and when continuing screwde on, pressing force is just concentrated mainly on
At limited block, and the pressing force at arc convex remains unchanged；When release bolt, when Bolt Torque decays, first at limited block
Pressing force decaying, and the pressure value at arc convex is substantially unattenuated.Therefore, which, which can be effectively prevented, starts
Machine during the work time, as cold and hot deformation and the variation of the Bolt Torques such as vibratory impulse caused by exhaust pipe gasket fatigue,
Occur so as to cause the phenomenon that leakproofness failure, substantially increases the leakproofness between engine cylinder cover and exhaust pipe, effectively protect
The normal work and safety of engine are demonstrate,proved.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below to embodiment or
Attached drawing needed to be used in the description of the prior art is briefly described, it is clear that, the accompanying drawings in the following description is only
The embodiments of the present invention without creative efforts, may be used also for those of ordinary skill in the art
To obtain other attached drawings according to the attached drawing of offer.
Fig. 1 is the utility model embodiment institute exhaust pipe assembling structure schematic diagram；
Fig. 2 is the structural schematic diagram of exhaust pipe gasket disclosed in the utility model embodiment；
Fig. 3 is the schematic diagram of the section structure of exhaust pipe gasket disclosed in the utility model embodiment.
Wherein, the names of the parts are as follows:
1- exhaust pipe, 2- engine cylinder cover, 3- the first single layer gasket, 4- the second single layer gasket, 5- limited block, 6- bolt.
Specific embodiment
In view of this, the core of the utility model is to provide a kind of exhaust pipe gasket, engine cylinder can be effectively improved
Leakproofness between lid and exhaust pipe, to guarantee the normal work and safety of engine.
In order to make those skilled in the art better understand the scheme of the utility model, connection with figures and specific implementation below
The utility model is described in further detail for mode.
As shown in Figure 1, exhaust pipe gasket disclosed in the utility model embodiment, is set to exhaust pipe 1 and engine cylinder
Between lid 2, exhaust pipe 1 and engine cylinder cover 2 are connected by bolt 6, comprising: the first single layer gasket 3 and the second single layer gasket 4；
