Abstract
A kind of grooved metal gasket belongs to sealing element technical field.It includes flat shim ontology, and metal gear ring is distributed in the ontology upper and lower end face, and the metal gear ring is alternately formed by connecting by radial arc and anti-radial arc, the gear ring that overall undulate surrounds.The metal-toothed circle forms irregular sealing space, internal buffering area can effectively prevent because when external and internal pressure changes greatly to the blastic deformation of gear ring.The metal-toothed is arc, and the height of tooth differs, and has the difference in height of very little per two adjacent teeth, can reach the labyrinth sealing action that traditional grooved metal gasket all has, be processed into arc-shaped gear in addition and be also avoided that traditional pointed tooth causes to damage to flange face.
Description
Technical field
The utility model is related to a kind of gasket seals, are specifically designed a kind of novel, good airproof performance grooved metal gasket.
Background technology
Grooved metal gasket:It is general to be processed into concentric groove, root in two faces of metal stainless steel flat shim with accurate lathe
According to different media, soft graphite, PTFE may be selected, without asbestos board or some other soft metal, be pasted onto two faces of gasket.
It can directly be used without sealant, and good sealing effect can be reached, but easily the surface of flange is made in high pressure occasion
Into loss.For tooth form combination mat using being gasket first under relatively low pretightning force, the sealant of soft surface avoids metal
Metal is in direct contact, and can reliably, closely be combined, metal flange is protected not to be damaged, even if in high load
Under.Tooth form combination mat is particularly suitable for high temperature, high pressure, the occasion of working condition alternation, in heat exchanger, container, reaction kettle
Flange connections are the ideal substitutes of conventional metals cladding gasket.
Nowadays grooved metal gasket in the market, gear ring are all the concentric circles of rule, under the working environment of high temperature and pressure easily
Tooth deformation occurs, leakproofness is caused to reduce, and the tooth processed easily causes to damage for pointed tooth to flange face, influences work effect
Rate increases production cost.
Utility model content
The purpose of this utility model is overcoming the shortcomings of existing technology, adapts to real needs, provides a kind of the new of good airproof performance
Type grooved metal gasket.
In order to realize the utility model aim, the utility model employs following technical solution：
Corrugated metal gear ring is distributed in a kind of grooved metal gasket, the ontology both ends of the surface, often enclose metal-toothed from inside to outside according to
Multiple buffering area is formed at the anti-radial arc of secondary concentric arrangement, most ring gear.
Preferably, the corrugated metal gear ring is alternately formed by connecting by radial arc and anti-radial arc, and then is formed
Multiple buffering area.
Preferably, the metal-toothed is arc-shaped gear.
Preferably, the height of the metal-toothed differs, and two adjacent teeth circle has fine height difference about 0.2mm.
The beneficial effects of the utility model are：The buffering area that arc gear ring is formed can effectively prevent because external and internal pressure becomes
To the blastic deformation of gear ring when changing larger.Per two adjacent metal-tootheds have subtle difference in height design can preferably to system into
Row labyrinth seal.In addition the design of arc-shaped gear is also avoided that traditional pointed tooth causes to damage to flange face.

Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
The technical solution of the utility model embodiment is clearly and completely described in embodiment.Obviously, described embodiment
It is the part of the embodiment rather than whole embodiments of the utility model.Based on the embodiment of described the utility model, sheet
Field technology personnel's all other embodiments obtained shall fall within the protection scope of the present invention.
With reference to Fig. 1, a kind of grooved metal gasket, it includes ontology, and metal gear ring is distributed in the ontology upper and lower ends face（1）,
The metal gear ring is by radial arc（4）With anti-radial arc（3）What alternating was formed by connecting, the gear ring that overall undulate surrounds.
Often enclose metal-toothed（2）Concentric arrangement successively from inside to outside, the anti-radial arc of most ring gear（3）Place forms multiple buffering area（5）.Institute
State buffering area（5）Effect be to can effectively prevent when sound external and internal pressure changes greatly to metal gear ring（1）Blastic deformation.Ginseng
According to Fig. 2, the metal-toothed on 3 gaskets（2）For arc-shaped gear, and height is different, specifically per adjacent two metal-toothed（2）Tooth height have
Fine height is poor, about 0.2 millimeter.Grooved metal gasket when being bonded with flange high tooth contacted at first with flange face, when ambient pressure compared with
High metal tooth when big（21）It is deformed to low metal tooth（22）Identical height, at this time whole metal-tootheds（2）All contacted with flange face, it is close
Envelope property greatly enhances.When internal pressure is larger, the buffering area on gasket can suitably slow down pressure, prevent pressure excessive to metal
Tooth（2）It causes blastic deformation and leakproofness is made to reduce or even directly contribute internal flow leakage.
In conclusion the grooved metal gasket involved by the utility model, it, can be very well by the design of buffering area and stage teeth
Adaptation high temperature and pressure alternation operating mode, gasket is unlikely to deform, and the leakproofness of whole system is made to be always maintained at well, this outer arcuate
The design of tooth is also avoided that traditional pointed tooth causes to damage to flange face.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
Other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
