Detailed description of the invention
With specific embodiment, technical scheme is further elaborated below in conjunction with the accompanying drawings.
Seeing the gasket seal shown in Fig. 1 to Fig. 6, it includes metallic inner 1, encloses and be located at perimembranous outside metallic inner 1
Metal outer shroud 2, the nonmetal sealing ring 3 being embedded between metal outer shroud 2 and metallic inner 1, the material choosing of nonmetal sealing ring 3
One in graphite, Muscovitum, politef.
Seeing shown in Fig. 3, Fig. 4, nonmetal sealing ring axially can be divided into three parts along self, is respectively master in the form of a ring
Body 31, lay respectively at the portion that is tightly connected 32 of main part 31 both sides axle head, the connecting portion 32 1 of main part 31 and both sides axle head
Body forms.Wherein, the inner side perimembranous of main part 31 matches with the outside perimembranous of metallic inner 1, the outside perimembranous of main part 31
Match with the inner side perimembranous of metal outer shroud 2, i.e. main part 31 is embedded regularly between metallic inner 1 and metal outer shroud 2.
Both sides axial end 31a of main part 31 is respectively lower than the metallic inner 1 of homonymy and/or the axle side end face of metal outer shroud 2, i.e. main body
The thickness in portion 31 is less than metallic inner 1 or metal outer shroud 2.
When gasket seal is not installed and used, axial end 32a of connecting portion 32 is higher than metallic inner 1 and/or metal outer shroud 2
Axle side end face, on the connecting portion 32 of both sides, between outside perimembranous and the inner side perimembranous of metal outer shroud 2 of connecting portion 32 formed ring
First holding tank 33 of shape, forms the second ring-type appearance between inner side perimembranous and the outside perimembranous of metallic inner 1 of connecting portion 32
Receive groove 34, the first above-mentioned holding tank 33 and the second holding tank 34 primarily to provide connecting portion 32 after being deformed its
The receiving space of portion of material.
When this gasket seal is located between two parts of connection to be sealed, nonmetal sealing ring 3 is axially compressed
After, the squeezed compression of connecting portion 32 and the portion of material of the first holding tank 33 and the second holding tank 34 connection portion 32 is filled out
Fill so that between outside perimembranous and the inner side perimembranous of metal outer shroud 2 of connecting portion 32, the inner side perimembranous of connecting portion 32 with in metal
It is affixed tactile between the outside perimembranous of ring 1 respectively.So, efficiently avoid gasket seal and installing and during use, non-
Metallic packing ring 3 material thereon after being squeezed is pressed on the end face of metallic inner 1 or metal outer shroud 2, thus
Avoid affecting the sealing reliability of gasket seal.When arranging, can be by outside circumference 32b of connecting portion 32 and inside circumference 32c
It is arranged respectively to inclined-plane, to provide spacing appropriate between itself and metal outer shroud 2 or metallic inner 1 and to accommodate space.
See shown in each accompanying drawing, in the inner side perimembranous of metal outer shroud 2 with both outside perimembranous of metallic inner 1 at least
Have in one and offer groove, when the main part 31 of nonmetal sealing ring 3 is embedded between metallic inner 1 and metal outer shroud 2 its
On at least part be embedded in above-mentioned groove.So can be effectively improved the outside week of nonmetal sealing ring 3 and metallic inner 1
Between portion or and the inner side perimembranous of metal outer shroud 2 between contact stress, thus prevent gasket seal in the mistake of installation and transportation
Cheng Zhong, nonmetal sealing ring 3 occurs to loosen or split away off and cause gasket seal between metallic inner 1 and metal outer shroud 2
Damage.
Above-mentioned groove may be configured as the most in the form of a ring, and the longitudinal cross-section of groove can be dentation or arc shape, certainly
Can also be other shape, as long as it can be for non-on the premise of not affecting metallic inner 1 or metal outer shroud 2 self performance
Last point of metallic packing ring 3 is embedded.
In the present embodiment, see shown in Fig. 2 to Fig. 6, the outside perimembranous of metallic inner 1 offer the first groove 11,
Offering the second groove 21 in the inner side perimembranous of metal outer shroud 2, in the inner side perimembranous of main part 31, at least part is embedded the
In one groove 11, outside it, in perimembranous, at least part is embedded in the second groove 21.So, the inner side of nonmetal sealing ring 3
Between the outside perimembranous of perimembranous and metallic inner 1, the inner side perimembranous of the outside perimembranous of nonmetal sealing ring 3 and metal outer shroud 2 it
Between contact stress be obtained for effective increase, it is possible to prevent gasket seal because nonmetal sealing ring 3 comes off further
The damage caused.
Specifically, the first groove 11 extends in the outside perimembranous of metallic inner 1 in the form of a ring, and the second groove 21 is outside metal
Extend the most in the form of a ring in the inner side perimembranous of ring 2.First groove 11 can be respectively provided with one or more with the second groove 21, works as setting
For time multiple, multiple first grooves 11 are distributed along its axially spaced-apart in the outside perimembranous of metallic inner 1, multiple second grooves 21
The inner side perimembranous of metal outer shroud 2 is distributed along its axially spaced-apart.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art's energy
Solution present disclosure much of that is also implemented according to this, can not limit the scope of the invention with this.All according to present invention spirit
The equivalence that essence is made changes or modifies, and all should contain within protection scope of the present invention.
