Description
Technical field
The utility model relates to a kind of gasket seal, particularly relates to a kind of metal ring pad of multi-layer structure.
Background technique
Metal annular gasket becomes sectional shape to be the solid metal pad of octagon or ellipse by metal material processing, has radial seal energized by internal pressure effect.Therefore metal annular gasket is the inside and outside contacts side surfaces of back cushion sheet and flange dovetail groove, and form sealing by compressing.Metal ring pad derives from the U.S. the earliest, field of boilers is used first in the twenties in 20th century, for the sealing of manhole cover, autoclave and other containers, especially come into one's own in Petroleum Production and petroleum refining industry later, along with the temperature and pressure of steam power plant increases, the purposes of metal ring pad is just more and more extensive.Because metal annular gasket specification is not of uniform size, and its sealing gasket required precision is very high, product surface has not allowed any colliding with, defect etc.In reality use and handling process, metal annular gasket easily collides with, and causes its sealing effect not good, and tradition installs effort compared with the metal ring pad of large gauge, needs multi-user collaborative operation during installation, and workman easily damages when operating and injures by a crashing object, there is potential safety hazard.
Model utility content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of and prevents from colliding with, simple installation, sealing effect are good, increase work efficiency, appearance looks elegant and the metal ring pad eliminated safe hidden trouble.
The utility model solves the problems of the technologies described above adopted technological scheme: comprise metal ring, rubber and plastic ring and plastic tape, and this metal ring outer surface is with rubber and plastic ring, and be stained with plastic tape at rubber and plastic ring surface, described rubber and plastic ring is bonded in metal ring outer surface horizontal segment.
Further, described metal ring is divided into Octagon and ellipse.
Compared with prior art, the utility model has the advantage of: the utility model structure is simple, metal ring outer surface, with rubber and plastic ring, is increased work efficiency, is eliminated safe hidden trouble, rubber and plastic ring surface has been stained with plastic tape in addition, appearance looks elegant, be convenient to distinguish metal ring pad kind, the utility model is reasonable in design, good airproof performance, is applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is partial sectional view of the present utility model;
Fig. 2 is whole-cutaway view of the present utility model.
Embodiment
As shown in Figure 1-2, a metal ring pad for multi-layer structure, comprises metal ring 1, rubber and plastic ring 2 and has plastic tape 3, and metal ring 1 cross section is Octagon or ellipse, metal ring 1 external diameter surface is stained with rubber and plastic ring 2, structure is simple, is convenient to workers carry, has enclosed plastic tape 3 in rubber and plastic ring 2 neutral position, for distinguishing different metal ring pad, color clear, distinguishes simple, appearance looks elegant.
During carrying, erect by metal ring pad, make rubber and plastic ring 2 and earth surface, workers roll's metal ring pad, rubber and plastic ring 2 well protects metal ring pad from colliding with.
During use, between dovetail groove the utility model being arranged on two flange plate, the chamfering of metal ring pad contacts with inside dovetail groove two, and with flange plate pressure increase, metal ring pad produces deformation, until metal ring pad and dovetail groove are close to, and formation excellent sealing.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technological scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
Claims (2)
