Abstract
A kind of novel gas-liquid inversion of phases high-temperature sealing gasket of the utility model and the sealing device including it, gasket includes two metal gaskets, middle position is provided with the circular ring shape convex ribs of outwardly convex between two metal gaskets, the liquid vaporized at high temperature is injected in circular ring shape convex ribs, two metal gasket outer welding, the groove matched with circular ring shape convex ribs is provided on flange, circular ring shape convex ribs are embedded in groove, and are compressed circular ring shape convex ribs in a groove when liquid vaporizes at high temperature.Increase a circular ring shape protrusion on two pieces of common metal gaskets, it, which is formed by space, pours water or other liquid, before and after gasket is mounted on such as booster when flange, under the action of the high-temperature gases such as exhaust, heated liquid is vaporized into gas, pressing force is generated after volume acute variation, gasket outer layer is pressed in the corresponding groove of flange and play the role of reinforcing sealing when high temperature, while temperature is higher, the pressing force of gasket is bigger, it is ensured that seals under high temperature abundant.
Description
Technical field
The utility model relates to gasket seal technical fields, more particularly to a kind of novel gas-liquid inversion of phases elevated-temperature seal pad
Piece and sealing device including it.
Background technique
At present in automotive engine applications, for the junction for being in high temperature, main sealing means to be applied are still use
Metal gasket including single layer and multilayer mode, and on metal gasket punching press convex epirelief to ensure under the pretightning force of connecting flange
Gasket can compress joint face and realize sealing, but the gasket before and after the booster of the large-duty engine excessively high for temperature, still
The problems such as often will appear gas leakage caused by seal failure.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of novel gas-liquid inversion of phases elevated-temperature seal
Gasket and sealing device including it.
The utility model is to solve above-mentioned technical problem by following technical proposals:
The utility model provides a kind of novel gas-liquid inversion of phases high-temperature sealing gasket, it is characterized in that comprising two gold
Belong to gasket, middle position is provided with the circular ring shape convex ribs of outwardly convex between described two metal gaskets, and the circular ring shape is convex
The liquid vaporized at high temperature, described two metal gasket outer welding are injected in muscle.
The utility model also provides a kind of sealing device, it is characterized in that comprising liquid phase modification high-temperature sealing gasket
And flange, the groove matched with circular ring shape convex ribs is provided on the flange, the circular ring shape convex ribs are embedded in groove, and
Circular ring shape convex ribs are compressed in a groove when liquid vaporizes at high temperature.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get the utility model respectively compared with
Good example.
The positive effect of the utility model is:
The utility model increases a circular ring shape protrusion on two pieces of common metal gaskets, is formed by space and pours
Water or other liquid, before and after gasket is mounted on such as booster when flange, under the action of the high-temperature gases such as exhaust, liquid
Heated to be vaporized into gas, gasket outer layer is pressed in the corresponding groove of flange to play and add by generation pressing force after volume acute variation
The effect sealed when strong high temperature, while temperature is higher, the pressing force of gasket is bigger, it is ensured that seals under high temperature abundant.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the novel gas-liquid inversion of phases high-temperature sealing gasket of the utility model preferred embodiment.
Fig. 2 is the cross-sectional view of A-A in Fig. 1.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of novel gas-liquid inversion of phases high-temperature sealing gaskets, including two metals
Gasket 1, middle position is provided with the circular ring shape convex ribs 2 of outwardly convex between described two metal gaskets 1, and the circular ring shape is convex
The liquid 3 vaporized at high temperature, described two 1 outer of metal gasket welding are injected in muscle 2.
The groove matched with circular ring shape convex ribs 2 is provided on flange, the circular ring shape convex ribs 2 are embedded in groove, and
Circular ring shape convex ribs 2 are compressed in a groove when liquid 3 vaporizes at high temperature.
The utility model increases a circular ring shape protrusion on two pieces of common metal gaskets, is formed by space and pours
Water or other liquid, before and after gasket is mounted on such as booster when flange, under the action of the high-temperature gases such as exhaust, liquid
Heated to be vaporized into gas, gasket outer layer is pressed in the corresponding groove of flange to play and add by generation pressing force after volume acute variation
The effect sealed when strong high temperature, while temperature is higher, the pressing force of gasket is bigger, it is ensured that seals under high temperature abundant.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the protection scope of the utility model.
