Description
Technical field
The utility model relates to a kind of pad, specifically a kind of spiral wound gaskets assembly and spiral wound gaskets, interior ring, centering ring.
Background technique
Spiral wound gaskets is widely used at numerous areas such as petrochemical industries, and using effect is very good.Spiral wound gaskets is by " V " shape or " W " shape metal tape and nonmetally is with overlappedly, and continuous winding forms, begin, end fixes metal tape with the spot welding mode.
The spiral wound gaskets assembly is divided into four kinds of forms, except basic model, commonly used be with in addition that inner ring type, band centering are ring-like, in band ring and centering ring-like.Describedly refer to be embedded with interior ring by the inner ring of spiral wound gaskets with inner ring type; With cover on the centering ring-like outer ring that refers to spiral wound gaskets, the centering ring is arranged; Ring and centering is ring-like refers to that the inner ring of spiral wound gaskets is embedded with interior ring in band, simultaneously on the outer ring also cover have centering to encircle.In above-mentioned several structural type, spiral wound gaskets is normally utilized in spiral wound gaskets working process with the socket of interior ring and/or centering ring and is wound around by " V " shape or " W " shape metallic strip structures the clamping form that rear formed annular card article matches with the annular slot of leaving on interior ring and/or centering ring, in case non-dismountable after assembling, if dismounting can make draw-in groove or card article local damage and can't reuse by force.
The not re-usable characteristics of spiral wound gaskets assembly, bring following problem: for the band inner ring type, the band centering ring-like and the band in the ring and ring-like these the three kinds of spiral wound gaskets assemblies of centering, in case the metal take-up strap lost efficacy, so not only spiral wound gaskets lost efficacy, and with it matching used interior ring and (or) the centering ring is also together discarded.Particularly in petrochemical plant pipeline pressure test, purging and test run stage, be connected frequently and remove due between flange valve, flanged fitting and the vessel flange mouth of pipe etc. and pipeline, cause a large amount of spiral wound gaskets to be damaged, the quantity that causes thus spiral wound gaskets to damage is generally more than a times of the positive usual amounts of spiral wound gaskets.particularity due to device technique media such as petrochemical industries, the interior ring of spiral wound gaskets assembly and (or) material of centering ring is comparatively expensive, as 0Cr18Ni9(304), 00Cr19Ni10(304L), 0Cr17Ni12Mo2(316), 00Cr17Ni14Mo2(316L), 0Cr18Ni10Ti(321), 0Cr18Ni11Nb(347) etc., in the process that the spiral wound gaskets assembly uses, holding flimsy part is generally metal take-up strap part, and the interior ring of spiral wound gaskets assembly and (or) centering ring is generally non-damageable, therefore, the spiral wound gaskets assembly that uses like this is a kind of huge waste to resource roughly.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, and a kind of simple in structure, flexible for installation, spiral wound gaskets assembly that reliability is high is provided.
The utility model also provide can composition versatile and flexible above-mentioned spiral wound gaskets assembly spiral wound gaskets, interior ring and centering ring.
Spiral wound gaskets described in the utility model, comprise shim body, be embedded with the inner support circle on the inner ring of described shim body, on the outer ring, cover has the outer support circle, the outer rim of described inner support circle and/or outer support circle is provided with the convex platform of annular, the thickness of described convex platform is preferably half of inner support circle and/or outer support circle total thickness less than the total thickness of inner support circle and/or outer support circle.
A kind of can with the matching used interior ring of spiral wound gaskets, comprise interior ring body, described interior ring body outer rim is provided with the lower convex platform of the annular corresponding with the convex platform of inner support circle, and the thickness of described lower convex platform is preferably half of interior ring body total thickness less than the total thickness of interior ring body.
A kind of can the ring with the matching used centering of spiral wound gaskets, comprise centering ring body, described centering ring body inner edge is provided with the lower convex platform of the annular corresponding with the convex platform of outer support circle, the thickness of described lower convex platform is preferably half of centering ring body total thickness less than the total thickness of centering ring body.
Evenly have a plurality of hollow outs on described centering ring body.
Described hollow out is circular or oval.
A kind of spiral wound gaskets assembly, comprise spiral wound gaskets claimed in claim 1 and coordinate the above-mentioned interior ring of socket with spiral wound gaskets and/or above-mentioned centering ring, described spiral wound gaskets and interior ring and/or centering ring coordinates install after, then through the screw thread connection or through the mode of rivet, convex platform is fixedly connected with lower convex platform.
The height of described convex platform and lower convex platform is consistent.
The thickness sum that the consistency of thickness of described inner support circle and outer support circle, described convex platform add lower convex platform is equal to or less than the thickness of inner support circle or outer support circle.
In in the utility model assembly, ring, centering ring can select one or simultaneously and spiral wound gaskets mix proportion spiral wound gaskets assembly described in the utility model according to specific needs, by design convex platform on inside and outside bracing ring, design lower convex platform simultaneously on interior ring and/or centering ring, and it is consistent with the lower convex platform height further to control convex platform, by the cooperation of upper and lower boss, realize the removable socket of spiral wound gaskets and interior ring and/or centering ring.For further guarantee socket firmly, avoid mutually throwing off between the spiral wound gaskets assembly, can connect or through the mode of rivet, convex platform is fixedly connected with lower convex platform by screw thread.
Further, in order to reduce as much as possible the consumption of metallic material, thereby produce larger economic benefits, can consider evenly to leave several hollow outs on the centering ring, it is circular or oval that these hollow outs are preferably.
Spiral wound gaskets described in the utility model, interior ring and centering ring structure are simple, processing, use very easy, can supporting flexible use; All can freely change when in spiral wound gaskets assembly described in the utility model, arbitrary assembly damages, again can not affect its sealing effect after supporting installation, solved the piping flange assembly and with the vessel flange mouth of pipe between be connected frequently and remove, cause a large amount of spiral wound gaskets to be damaged, the problem that the cost that must change whole gasket assembly and bring improves, effectively reduced cost, have wide market application foreground.
