Abstract
The utility model provides a novel flange gasket, belongs to the industrial goods, is to constitute its characterized in that by ripples tooth metal framework, flexible graphite layer, nonmetal hollow circle, locating ear, the connecting hole optimized: the concentric circles slot that is had mutual staggered particular form by the upper and lower surface through optimizing structure constitutes ripples tooth metal framework and flexible graphite layer complex, and locating ear opens with ripples tooth metal framework rigid coupling has the connecting hole, packs the nonmetal hollow circle who has chemical swelling agent and fastens at ripples tooth metal framework on the breach that the inner circle was left. The utility model discloses a solve the problem that the gasket seal ability descends under the high temperature condition, improved the application scope of gasket.
Description
Technical field
This utility model relates to a kind of industrial goods, especially a kind of ripple tooth metallic framework, soft graphite layer, nonmetal sky
Heart annulus, the novel flange pad that locating ring etc. is constituted.
Background technology
The kind of the flange gasket that currently there are is a lot, mainly has metallic gasket, non-metallic gasket and combination type
Pad.For the pad of these kinds, the most most successful is exactly corrugated serrated compound gasket, but it also has certain defective,
Seal request can not be fully met under hot conditions.Much to sealing and demand eager to the field that temperature requirement is higher
Plant performance more preferable novel flange pad, but do not have in the market to meet such flange gasket required.
Utility model content
This utility model aims to solve the problem that the problems referred to above, it is provided that a kind of novel flange pad, improves the close of conventional spacers
Feng Xing, and improve the heat-resisting ability of conventional spacers to a certain extent, its technical scheme used is as follows:
A kind of novel flange gasket, including ripple tooth metallic framework, soft graphite layer, nonmetal hollow ring, chucking lug,
Connecting hole.It is characterized in that: the ripple tooth metallic framework being had the concentric grooves mutually staggered to constitute by upper and lower surface and flexible stone
Layer of ink is combined, and chucking lug is affixed with metallic framework and has connecting hole, and the nonmetal hollow ring being filled with chemically expansible agent is tight
Gu at ripple tooth metallic framework on the breach that inner ring is outputed.
This utility model has the advantage that when room temperature works, under certain pre-tight stress, pad soft graphite layer with
Flange sealing surface is in close contact and realizes preliminary sealing, and it is many that the ripple toothing that ripple tooth metallic framework mutually staggers simultaneously realizes pad
Resealing.When the operating temperature of pad constantly increases, the extender expanded by heating in nonmetal cavity ring, compress gasket is soft
Property graphite linings and flange sealing surface, make pad have better seal when high temperature, novel flange pad is carried by three-layer sealed
The high scope of application of pad.
Accompanying drawing explanation
Accompanying drawing 1 is cross-sectional view of the present utility model;
Accompanying drawing 2 is perspective view of the present utility model;
In figure, 1, ripple tooth metallic framework, 2, soft graphite layer, 3 nonmetal hollow rings, 4, chucking lug, 5, connecting hole.
Detailed description of the invention
The utility model is described in further detail with example below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, a kind of novel flange gasket, including ripple tooth metallic framework 1, soft graphite layer 2, non-gold
Belong to hollow ring 3, chucking lug 4, connecting hole 5, it is characterised in that ripple tooth metallic framework 1 is combined with flexible graphite material 2, chucking lug
4 is affixed and have connecting hole 5 with ripple tooth metallic framework, and the nonmetal hollow ring 3 being filled with chemically expansible agent is fastened on ripple tooth
Metallic framework 1 is in the groove that inner ring is outputed.
In use, flange gasket is positioned by chucking lug 4, and is fixed on flange by connecting hole 5.Flange two
While apply pressure to pad soft graphite layer 2, during stress, comprcssive strength, soft graphite layer 2 due to ripple tooth metallic framework 1 are good
Pliability and resilience, make flange gasket sealing joint, when pad operating temperature raises, include the nonmetal of extender
Cavity ring 3 expanded by heating, compresses soft graphite layer 2, makes pad and flange contact tightr, and this novel flange pad solves height
The problem that during temperature, flange seal is the tightest, improves pad adaptability under the high temperature conditions.
The most by way of example this utility model is illustrated, but this utility model is not limited to above-mentioned being embodied as
Example, all any changes done based on this utility model or modification belong to the scope that this utility model is claimed.
