Abstract
The utility model discloses a multi-layer ripple mat, belonging to the technical field of a ripple mat. The multi-layer ripple mat comprises metal sheets with a wave-shaped cross section, wherein the ripple spaces of each metal sheet are the same; and the trough of each metal sheet and the peak of a metal sheet in contact therewith below are fixed. After multiple metal sheets are stacked in this way, the elastic deformation range is equivalent to the sum of the elastic deformation of all metal sheets, thus the elastic deformation range is greatly increased, and the requirements of the occasions with frequent change of temperature and pressure or old equipment suffering serious damage of flange surface and the like can be met. The same ripple space of each metal sheet ensures that each trough of the metal sheet can exactly correspond to the peak of the metal sheet below, and the welding fixation is facilitated.
Description
Technical field
The utility model relates to a kind of ripple pad, relates to a kind of multilayer corrugated pad specifically.
Background technique
The ripple pad is a kind of traditional sealing element, have make simple, rebound elasticity is good, the characteristics of good integrity, the ripple pad belongs to flexible pad; Tinsels such as brass commonly used, copper, corronil, steel, monel metal, lead are processed, and the cross section of tinsel is a wave-like, and working principle is to rely on the crest of tinsel to contact with sealing surface formation line; Because the high pressure of line contact; Make tinsel produce resiliently deformable, be adjacent to sealing surface all the time, compensating sealing surface uneven.Singly being used for some need be than the equipment of large compensation performance: change frequent occasion or the impaired serious used equipment of flanged surface etc. like temperature, pressure.The elastically-deformable scope of unitary piece of metal sheet is too little, can't fit tightly with sealing surface, therefore is necessary to improve.
Summary of the invention
The utility model provides a kind of multilayer corrugated pad to deficiency of the prior art, has increased the elastic strain scope of tinsel greatly.
For solving the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of multilayer corrugated pad; Comprise that cross section is corrugated tinsel; Said tinsel has more than two, and the ripple spacing of every said tinsel is identical, and the trough of every said tinsel fixes with the crest of the contacted tinsel with it that is positioned at the below.After the multi-disc tinsel adopted said method range upon range of, elastically-deformable scope was equivalent to the summation of all tinsels, and elastically-deformable scope increases greatly, can the satisfied temperature variation in pressure frequent occasion or the impaired serious used equipment of flanged surface etc.The ripple spacing of every said tinsel is identical to be can both be corresponding with the crest of below tinsel just for each trough that guarantees tinsel, fixes so that weld.
In the technique scheme, in order to increase sealability, the below of the tinsel of below is provided with Expanded graphite with being positioned in the top of the said tinsel that is positioned at the top.The Expanded graphite material is softer, and deformation and sealing surface form good applying easily.
In the technique scheme, said tinsel has two.
In the technique scheme, the said right ends that is positioned at the tinsel of top is a trough, and the said right ends that is positioned at the tinsel of below is a crest.
The beneficial effect of the utility model is: the range upon range of setting of multi-disc tinsel; Elastically-deformable scope is equivalent to the summation of all tinsels; Elastically-deformable scope increases greatly, can the satisfied temperature variation in pressure frequent occasion or the impaired serious used equipment of flanged surface etc.
Description of drawings
Fig. 1 is the utility model embodiment's a floor map.
Fig. 2 is the sectional view of Fig. 1 along A-A.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 and Fig. 2; A kind of multilayer corrugated pad; Comprise that two cross sections are corrugated tinsel 1,2; Tinsel 1,2 be shaped as annular, the thickness of tinsel 1,2 is between the 0.25-0.30mm, the trough of upper metal sheet 1 welds fixing with the crest of the contacted with it tinsel 2 that is positioned at the below mutually.For each trough that guarantees tinsel 1 can both be corresponding with the crest of tinsel 2 just, so that welding is fixing, the ripple spacing of tinsel 2 is identical with the ripple spacing of tinsel 1.
Be coated with Expanded graphite 3 on the below of the top of the tinsel 1 of top and the tinsel 2 that is positioned at the below.
Referring to Fig. 2, the right ends that is positioned at the tinsel 1 of top is a trough, and the said right ends that is positioned at the tinsel 2 of below is a crest.The two ends of tinsel 1,2 are weld just, and formation is sealed, and avoid scratching the workman.If other setting method, the two ends of tinsel 1,2 can form opening, scratch the workman easily.
According to the principle of the utility model, tinsel also can be arranged to three layers perhaps more than three layers.
