Abstract
The utility model relates to a multilayer toothed combined sealing gasket. The multilayer toothed combined sealing gasket comprises an elastic ring layer with rebound elasticity; the elastic ring layer is sandwiched between an upper metal ring and a lower metal ring, and the outer sides of the upper metal ring and the lower metal ring are provided with an outer metal ring which is fixedly connected with the upper metal ring and the lower metal ring; the outer surface of the upper metal ring, the outer surface of the lower metal and the upper and lower surfaces of the outer meta ring are provided with teeth; an upper flexible graphite ring is combined above the upper metal ring and the outer metal ring, and a lower flexible graphite ring is combined below the lower metal ring and the outer metal ring. The multilayer toothed combined sealing gasket has advantages that since the sealing gasket is provided with teeth, the connection between layers is very tight and the sealing gasket does not easily fall apart; the sealing gasket is more suitable for places of frequently alternating operating temperature, and the mechanical property and the sealing performance of the sealing gasket are better; the stress needed for realizing sealing is smaller.
Description
Technical field
The utility model relates to a kind of gasket seal.
Background technique
Existing gasket seal exists mainly with the form of wound gasket greatly.The wound gasket of large specification easily falls apart, and seals required stress larger, and operating temperature hand over limit frequently the sealability of occasion wound gasket need to improve.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing gasket seal, the utility model provide a kind of adapt to operating temperature hand over limit frequently occasion, mechanical property and sealability better, seal the multilayer profile of tooth combination seal pad that required stress is lower, be difficult for falling apart.
The technical scheme in the invention for solving the technical problem is: a kind of multilayer profile of tooth combination seal pad, comprises that one deck has elastic elasticity circular layer;
Described elasticity circular layer is sandwiched between metal ring and lower metal ring, and the outside of described upper metal ring and lower metal ring is provided with the outer metal ring affixed with it;
The upper and lower surface of the outer surface of described upper metal ring, the outer surface of lower metal ring, outer metal ring is equipped with profile of tooth;
The top of described upper metal ring, outer metal ring is compounded with Expanded graphite ring, and the below of described lower metal ring, outer metal ring is compounded with lower Expanded graphite ring.
Further, described elasticity circular layer is flexible graphite sheet material.Or: described elasticity circular layer is laminated by multilayered metal film.
Further, the width of the width of described elasticity circular layer, the width of upper metal ring, lower metal ring equates.
Further, the thickness of described outer metal ring is less than the thickness summation of metal ring, lower metal ring and elasticity circular layer.
Further, upper metal ring, lower metal ring all weld with described outer metal ring.
The utility model is the same with existing gasket seal in use, is clamped between flange.Elasticity circular layer can be realized according to the difference of external environment parameters autonomous flexible.
The beneficial effects of the utility model are: 1., owing to having profile of tooth, therefore connection is between layers very tight, is difficult for falling apart; 2. more adapt to operating temperature alternation occasion frequently, its mechanical property, sealability are better; 3. realize the required stress of sealing lower.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is skeleton schematic diagram of the present utility model.
Fig. 3 is plan view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of multilayer profile of tooth combination seal pad, comprises that one deck has elastic elasticity circular layer 1;
Described elasticity circular layer 1 is sandwiched between metal ring 2 and lower metal ring 3, and the outside of described upper metal ring 2 and lower metal ring 3 is provided with the outer metal ring 4 affixed with it;
The upper and lower surface of the outer surface of described upper metal ring 2, the outer surface of lower metal ring 3, outer metal ring 4 is equipped with profile of tooth;
The top of described upper metal ring 2, outer metal ring 4 is compounded with Expanded graphite ring 5, and the below of described lower metal ring 3, outer metal ring 4 is compounded with lower Expanded graphite ring 6.The same with existing gasket seal in use, be clamped between flange.Elasticity circular layer 1 can be realized according to the difference of external environment parameters autonomous flexible.
Elasticity circular layer 1 can be selected flexible graphite sheet material, also can be laminated by multilayered metal film, certainly can also adopt other to have flexible material or mode of structure, such as high temperature resistant elastomeric fiber etc.
In the present embodiment, the width of the width of described elasticity circular layer 1, the width of upper metal ring 2, lower metal ring 3 equates, the thickness of described outer metal ring 4 is less than the thickness summation of metal ring 2, lower metal ring 3 and elasticity circular layer 1, upper metal ring 2, lower metal ring 3 all weld (certainly also can adopt other modes to realize affixed) with described outer metal ring 4, thereby adopt criss-crossing spot welding to form solder joint 7.This kind of structure make the sealability of gasket seal and mechanical property more excellent.
