Abstract
The open one of the utility model can locate mode vent systems special sealing pad, to comprise slice and bottom sheet, described upper slice and bottom sheet be circular; Described upper slice be provided with the first convex tendon, described bottom sheet is provided with the second convex tendon coordinated with described first convex tendon, and described first convex tendon and the second convex tendon coordinate and form hollow ring.Compared with existing conventional pads, the utility model can form effective sealing strip with flange after mounting by the cooperation of the first convex tendon and the second convex tendon, and its sealability is greatly improved, and also improves emission performance and the fordability of car load simultaneously; Can realize location of the present utility model by positioning boss, substantially increase efficiency of assembling, and the accuracy of location also improves greatly.
Description
Technical field
The utility model belongs to automobile exhaust system outlet pipe and connects and field of sealing technology, is specifically related to a kind of vent systems special sealing pad.
Background technique
Exhaust sealing pad is the special obturator of engine exhaust system.Along with country is to the raising of automobile exhaust emission standard, the technical merit of motor and emission aftertreatment also constantly improves, and the quality of vent systems sealability directly can affect the emission performance of car load.Current vent systems sealing between two flanges, is provided with flat pad to realize sealing effect, and flat pad has many drawbacks: pad planeness not easily ensures, high to manufacture requirement on machining accuracy; Cannot locate during assembling; Not easily realize quick mounting, assemble length consuming time; Assemble easy appearance not in place poorly sealed etc.
Model utility content
In order to overcome the above problems, the purpose of this utility model is to provide one can locate mode vent systems sealing gasket, and its structure is simple, accurate positioning, and efficiency of assembling is high, and sealing is reliable, and anti-gas-leak water-inlet-proof is effective, and materials are few, low cost of manufacture.
For achieving the above object, the utility model design can locate mode vent systems special sealing pad, it is characterized in that: to comprise slice and bottom sheet, described upper slice and bottom sheet be circular; Described upper slice be provided with the first convex tendon, described bottom sheet is provided with the second convex tendon coordinated with described first convex tendon, and described first convex tendon and the second convex tendon coordinate and form hollow ring.
Further, described bottom sheet is provided with positioning boss, and described positioning boss end is connected with described bottom sheet inwall end.Like this, during assembling, positioning boss is stretched in the endoporus of flange, utilize positioning boss can realize the location of sealing gasket, the efficiency of assembling improved greatly and the accuracy of location.
Further, described upper slice and bottom sheet spot-welded into a single integrated structure.Like this, first upper and lower can be assembled together, ensure that assembly precision and the sealing effect of upper and lower; Meanwhile, for follow-up assembling provides sealing and location base reliably.
Further, the cross section of described first convex tendon and the second convex tendon is arc-shaped.
The beneficial effects of the utility model are: compared with existing conventional pads, the utility model can form effective sealing strip with flange after mounting by the cooperation of the first convex tendon and the second convex tendon, its sealability is greatly improved, and also improves emission performance and the fordability of car load simultaneously; Can realize location of the present utility model by positioning boss, substantially increase efficiency of assembling, and the accuracy of location also improves greatly.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model
Fig. 2 is the cross-sectional schematic after the utility model assembling
In figure: upper slice 1, bottom sheet 2, positioning boss 3, flange 4;
Wherein: the first convex tendon 1.1, second convex tendon 2.1.
Embodiment
As depicted in figs. 1 and 2, the utility model design can locate mode vent systems special sealing pad, comprise slice 1 and a bottom sheet 2, described upper slice 1 and bottom sheet 2 be circular; Described upper slice 1 be provided with the first convex tendon 1.1, described bottom sheet 2 is provided with the second convex tendon 2.1 coordinated with described first convex tendon 1.1, and described first convex tendon 1.1 and the second convex tendon 2.1 coordinate and form hollow ring.Like this, reliable sealing is formed by the cooperation of two convex tendons and end face of flange.
Again as depicted in figs. 1 and 2, further, described bottom sheet 2 is provided with positioning boss 3, and described positioning boss 3 end is connected with described bottom sheet 2 inwall end.Like this, stretched into by positioning boss 3 in the endoporus of flange 4 during assembling, utilize positioning boss 3 can realize the location of sealing gasket, the efficiency of assembling improved greatly and the accuracy of location, moreover can also play the effect of sealing strip.
Further, described upper slice 1 and bottom sheet 2 spot-welded into a single integrated structure.Like this, first upper and lower can be assembled together, ensure that assembly precision and the sealing effect of upper and lower; Meanwhile, for follow-up assembling provides sealing and location base reliably.
As shown in Figure 1, further, the cross section of described first convex tendon 1.1 and the second convex tendon 2.1 is arc-shaped.
