Abstract
The utility model discloses a kind of gasket seal, including metallic inner, enclose the metal outer shroud being located at described metallic inner periphery, the sealing ring being embedded between described metallic inner and described metal outer shroud, between outside perimembranous and the inner side perimembranous of described metal outer shroud of described metallic inner, be installed with dowel.When this gasket seal work in High Temperature High Pressure and pressure medium have drastically change time, metallic inner remains enough rigidity and intensity, thus ensure that seal ring seal stress is constant, do not have the phenomenon that metallic inner makes because of unstability sealing ring stress lack, and then ensure that the job stability of gasket seal and the sealing reliability of sealing system.
Description
Technical field
This utility model relates to a kind of gasket seal, particularly relates to a kind of high temperature and temperature, that pressure alternation seals is close
Gasket.
Background technology
Gasket seal of the prior art, the pad as disclosed in Chinese patent CN 202349208 U, it includes gold
Belong to internal ring, enclose and be located at the metal outer shroud of described metallic inner periphery and be embedded between described metallic inner and metal outer shroud
Such as nonmetal sealing rings such as pure graphite annulus.But, when gasket seal pressure in the industrial departments such as nuclear power, thermoelectricity, the energy
When Force system seals, the diameter dimension of gasket seal is the biggest, and gasket seal is generally in the extreme operating conditions such as High Temperature High Pressure
Under working media in.When working media is drastically lowered the temperature, it is easily caused metallic inner unstability and causes middle pure graphite annulus close
Envelope stress disappearance, thus cause metallic inner to come off and cause the inefficacy of whole sealing system.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming prior art, it is provided that a kind of seal more reliable gasket seal, with
Improve its job stability in sealing system.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of gasket seal, including metallic inner,
Enclose the metal outer shroud being located at described metallic inner periphery, the sealing being embedded between described metallic inner and described metal outer shroud
Ring, is installed with dowel between outside perimembranous and the inner side perimembranous of described metal outer shroud of described metallic inner.
Preferably, described dowel extends continuously in a circumferential in the outside perimembranous of described metallic inner.
Further, described metal outer shroud, described metallic inner and described dowel are wholely set.
Further, the thickness of described dowel is the 10%～50% of the outer ring thickness of described metallic inner/described metal.
Further, the thickness of described dowel is the 15%～25% of the outer ring thickness of described metallic inner/described metal.
Further, described gasket seal includes annular gasket body, in the two axial ends of described annular gasket body respectively
Offering cannelure, form described dowel between the bottom side cell wall of cannelure described in two, the inner side of described cannelure forms institute
Stating metallic inner, the outside of described cannelure forms described metal outer shroud, is all embedded with described sealing in each described cannelure
Ring.
Preferably, described sealing ring has two, and sealing ring described in two lays respectively at the axial both sides of described dowel, and institute
The axle head stating sealing ring exceeds the axial end of described metallic inner and described metal outer shroud.
Preferably, described sealing ring is graphite annulus.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that this practicality is new
In the gasket seal of type, by arranging dowel, metallic inner is coupled together with metal outer shroud so that gasket seal entirety
Rigidity gets a promotion, when this gasket seal work in High Temperature High Pressure and pressure medium have drastically change time, metallic inner is protected all the time
Hold enough rigidity and intensity, thus ensure that seal ring seal stress is constant, do not have metallic inner and make sealing because of unstability
The phenomenon of Zernike annular polynomial disappearance, and then ensure that the job stability of gasket seal and the sealing reliability of sealing system.
Accompanying drawing explanation
Accompanying drawing 1 is the sectional structure schematic diagram of gasket seal of the present utility model.
Wherein: 1, metallic inner；2, metal outer shroud；3, dowel；4, sealing ring.
Detailed description of the invention
With specific embodiment, the technical solution of the utility model is further elaborated below in conjunction with the accompanying drawings.
Gasket seal shown in Figure 1, it include metallic inner 1, enclose be located at metallic inner 1 periphery metal outer shroud 2,
The sealing ring 4 being embedded between metallic inner 1 and metal outer shroud 2, wherein, the outside perimembranous of metallic inner 1 and metal outer shroud 2
It is installed with dowel 3 between the perimembranous of inner side.
Shown in Figure 1, in the present embodiment, dowel 3 is in the outside perimembranous and metal outer shroud 2 of metallic inner 1
Extend continuously in a circumferential between the perimembranous of side, and dowel 3 is wholely set with metallic inner 1, metal outer shroud 2.This gasket seal exists
Add man-hour, can the circular annular gasket body of first molding one, then offer respectively in the two axial ends of this annular gasket body
Cannelure, just forms dowel 4 between the bottom side cell wall of two cannelures, and the inner side of cannelure forms metallic inner 1, cannelure
Outside then forms metal outer shroud 2.And sealing ring 4 has two, it is embedded respectively in two cannelures.The two sealing ring 4 position respectively
In the axial both sides of dowel 3, and the axle head of sealing ring 4 exceeds the axial end of metallic inner 1 and metal outer shroud 2, specifically, close
Seal ring 4 can use graphite annulus.
When arranging, thickness is metallic inner 1/ metal outer shroud 2 thickness the 10%～50% of dowel 3 should be made, this number
According to preferably using 15%～25%.Wherein metallic inner 1 is identical with the thickness of metal outer shroud 2.
In some embodiment do not recommended, it is also possible to dowel 3 is set to multi-segment structure, this multistage dowel 3
It is connected between metallic inner 1 and metal outer shroud 2 circumferentially spacedly.Sealing ring 4 is provided with two, two sealing rings 4
Lay respectively at the axial both sides of dowel 3.But this kind of version processing mode is extremely complex.
To sum up, being coupled together by dowel 3 with metal outer shroud 2 by metallic inner 1, this makes the firm of gasket seal entirety
Property gets a promotion.When this gasket seal work in High Temperature High Pressure and pressure medium have drastically change time, metallic inner 1 all the time with gold
Belonging to outer shroud 2 to be fixed together, metallic inner remains enough rigidity and intensity, thus ensures that sealing ring 4 Sealing Stress is permanent
Fixed, do not have the phenomenon that metallic inner makes because of unstability sealing ring stress lack, and then ensure that the work of gasket seal is steady
Qualitative and the sealing reliability of sealing system.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it
In.
