Abstract
The utility model discloses a high-sealing flange gasket for automobile exhaust pipes. The high-sealing flange gasket comprises a gasket body, a sealing device and a fixing device. The gasket body is provided with a through hole at the center, the through hole is identical to a flange through hole in size, the sealing device is connected with the gasket body and locates at the edge of the through hole, and the fixing device is arranged on the gasket body. The sealing device is characterized in that a plurality of annular protrusions are arranged on two sides of the gasket body. The fixing device is characterized in that raised pasting pieces are arranged on two sides, close to the annular protrusions, of the gasket body. By the arrangement, leakage is prevented since two flange gaskets are avoided, and leakproofness is further enhanced by the arrangement of hot-melt sealant. The high-sealing flange gasket is simple in manufacturing process and low in cost.
Description
Technical field
The effective high leak tightness flange gasket of a kind of flange gasket, particularly a kind of automobile exhaust.
Background technique
Along with country to environmental protection, the continuous attention of low energy consumption, the sealing that guarantees vent systems is more and more paid attention to, for strengthening the sealing between automobile exhaust pipe joint face-flange, mostly adopt the identical flange gasket of two chip sizes in prior art, between connect with flexible material, connect and all can produce leakage in any case between two flange gaskets, thereby sealing can not be guaranteed, and prior art is unresolved this problem also.
The model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of sealing high, and technique is simple, the effective high leak tightness flange gasket of the automobile exhaust that cost is low.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
The effective high leak tightness flange gasket of automobile exhaust, comprising: central position is provided with the shim body of shim through bore, and through hole is identical with the flange clear size of opening; Also comprise: be connected in shim body and be positioned at the seal arrangement at through hole edge, be placed in the fixing device on shim body; Seal arrangement is formed with: a plurality of annular protrusions that are placed in the shim body both sides; Fixing device forms to be had: be placed in the shim body both sides and near the sticking piece of annular protrusion.
The effective high leak tightness flange gasket of aforesaid automobile exhaust, fixing device also forms and has: be placed on shim body and with respect to the pad mounting hole of flange mounting hole.
The effective high leak tightness flange gasket of aforesaid automobile exhaust, sticking piece is hot-melt sealant.
The effective high leak tightness flange gasket of aforesaid automobile exhaust, the thickness of sticking piece equals the height of annular protrusion.
The effective high leak tightness flange gasket of aforesaid automobile exhaust, annular protrusion is 4 at the number of above-mentioned shim body one side.
Usefulness of the present utility model is: the utility model avoids using two flange gaskets, has avoided leakage, hot-melt sealant the further sealing that increased is set.And preparation process of the present utility model is simple, and cost is low.
Description of drawings
Fig. 1 is a kind of embodiment's of the present utility model plan view.
Fig. 2 is the sectional view of a kind of embodiment A of the present utility model-A face.
The implication of reference character in figure:
1 shim through bore, 2 shim body, 3 annular protrusions, 4 pad mounting holes, 5 hot-melt sealants.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done concrete introduction.
The effective high leak tightness flange gasket of automobile exhaust comprises: central position is provided with the shim body 2 of shim through bore 1, and through hole is identical with the flange clear size of opening; Also comprise: be connected in shim body 2 and be positioned at the seal arrangement at through hole edge, be placed in the fixing device on shim body 2.
Seal arrangement is formed with: a plurality of annular protrusions 3 that are placed in shim body 2 both sides; Need to prove, inferior annular projection 3 is the both sides in shim body 2; So just avoided using two pads, avoided leakage.As a kind of preferred, annular protrusion 3 is 4 at the number of above-mentioned shim body 2 one sides; The width of seal arrangement, just less than the width of hot-melt sealant 5, so more is conducive to guarantee sealing like this.
Fixing device forms to be had: be placed in shim body 2 both sides and near the sticking piece of annular protrusion 3; Be placed on shim body 2 and with respect to the pad mounting hole 4 of flange mounting hole.Be hot-melt sealant 5 as a kind of preferred sticking piece; Hot-melt sealant 5 is DF-8619 butyl hot-melt sealants 5 that east product of rubber and plastic Co., Ltd produces, this sealer heat is just understood toughness, thereby can first flange gasket be installed on pipeline or flange, heat again pad, hot-melt sealant 5 viscosity become large, cling between pad and flange the effect of not only playing fixing effect but also further sealing; And this product of DF-8619 butyl hot-melt sealant 5 has good high temperature resistant character, can adapt to the hot environment in automobile exhaust pipe.
Need to prove, the thickness of hot-melt sealant 5 will equal the height of annular protrusion 3, could further guarantee sealing like this, if can not play the effect of its sealing greater than annular protrusion 3; If less than, hot-melt sealant 5 can not be completed effect fixing and sealing.
Above demonstration and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
Claims (5)
