Abstract
The utility model discloses a sealing gasket for an automobile exhaust system. The sealing gasket is used in coordination with a flange (5) and comprises a first sealing strip (1) and a second sealing strip (3); and a sealing convex ring (2) is arranged between the first sealing strip (1) and the second sealing strip (3). By adopting the technical scheme, compared the sealing gasket for the automobile exhaust system with a conventional gasket, the sealing performance of the sealing gasket is greatly improved, and the sealing performance of the automobile exhaust system and the exhaust performance of the whole vehicle are improved.
Description
Technical field
The utility model relates to a kind of engine exhaust system, and more particularly, the utility model relates to a kind of automobile exhaust system gasket seal.
Background technique
Along with the raising of country to automobile exhaust emission standard, the technical merit of motor and discharging reprocessing also constantly improves, the quality of vent systems sealability then directly can influence the emission level of car load, vent systems sealing at present is to be provided with the effect that pad reaches sealing between two flanges, but As time goes on, the sealing effect of this pad descends gradually, finally influences the emission performance of car load.
The model utility content
Problem to be solved in the utility model provides a kind of automobile exhaust system gasket seal, its objective is to improve the automobile exhaust system sealability, improves the emission performance of car load.
To achieve these goals, the technological scheme taked of the utility model is:
A kind of automobile exhaust system gasket seal provided by the utility model is used with flange, comprises first sealing strip and second sealing strip, is provided with the sealing bulge loop between described first sealing strip and second sealing strip.
On described flange, be provided with and seal the bulge loop corresponding grooves.
Described sealing bulge loop is connected with described groove by compressing tablet.
Described sealing bulge loop is that metallic material is made.
Adopt technique scheme, this automobile exhaust system gasket seal is compared with existing conventional pads, and its sealability is greatly improved, and has improved the sealability of automobile exhaust system, has also improved the emission performance of car load simultaneously.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model A-A sectional structure schematic representation;
Fig. 3 is the structural representation of the utility model flange;
Fig. 4 is the utility model B-B sectional structure schematic representation;
Fig. 5 is the structural representation that the utility model is connected with flange.
Be labeled as among the figure:
1, first sealing strip, 2, the sealing bulge loop, 3, second sealing strip, 4, compressing tablet, 5, flange, 6, groove.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize improving the automobile exhaust system sealability, improve the emission performance of car load.The technological scheme that the utility model is taked is:
To shown in Figure 5, this automobile exhaust system gasket seal provided by the utility model is used with flange 5, comprises first sealing strip 1 and second sealing strip 3 as Fig. 1, is provided with sealing bulge loop 2 between described first sealing strip 1 and second sealing strip 3.
Adopt technique scheme, compare with existing conventional pads, its sealability is greatly improved, and has improved the sealability of automobile exhaust system, has also improved the emission performance of car load simultaneously.
To shown in Figure 5, on described flange 5, be provided with and seal bulge loop 2 corresponding grooves 6 as Fig. 1.
Adopt technique scheme, described sealing bulge loop 2 is embedded in the described groove 6, two flanges, 5 usefulness bolts are connected, out-of-date as air communication, will form a kind of three-dimensional sealing, reach the better seal effect.
To shown in Figure 5, described sealing bulge loop 2 is connected with described groove 6 by compressing tablet 4 as Fig. 1.
Described sealing bulge loop 2 is that metallic material is made.
Adopt technique scheme, out-of-date as air flow stream, at first pass through first sealing strip 1 of pad inboard, because planeness of flange, factors such as pad machining error, and under special operation condition, exhaust pressure is bigger, inner seal can not reach the sealing effect of expection, therefore, the part air-flow can arrive the sealing bulge loop 2 at groove 6 places, and the pressure of air-flow can produce certain pressure to the inboard of sealing bulge loop 2, at this moment seals bulge loop 2 and has the tendency that expands outwardly, the outside of sealing bulge loop 2 and the outside of groove 6 will fit tightly like this, because air-flow can produce certain pressure difference when mobile, therefore, sealing will reach extraordinary effect, also have second sealing strip 3 in sealing bulge loop 2 outsides simultaneously, this three-layer sealed mode is compared with common sealing means and will be got well a lot.
The technical scheme that the utility model adopts compared with prior art, has obvious difference, possessed substantial characteristics, and obtained technically progress, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
