Abstract
A kind of ellipse bipeltate compound sealing strip is provided, including high resiliency outer rubber layer, the cross section I of the high resiliency outer rubber layer is ellipse, is axially arranged with ellipse through hole inside the high resiliency outer rubber layer, compound in the ellipse through hole to be provided with bipeltate.Compound sealing strip is made using high elastic rubber and bipeltate in the utility model, can effectively solve the problem that internal stress existing for rubber weather strip made of existing homogenous material it is bigger, using after deformation elasticity be deteriorated, it is easy to aging, it is yielding damage come off, service life is short the problem of, its is simple in construction, it is easy to install and use, in light weight, manufacturing cost is low.
Description
Technical field
The utility model category mechanical seal device manufacturing technology field, and in particular to a kind of ellipse bipeltate is compound close
Strip of paper used for sealing.
Background technology
There are liquid or gas in EMUs, locomotive, transformer, sewing machine, automobile, motorcycle, petrochemical industry, high-voltage switch gear etc.
In sealing industry in the equipment manufacturing technical field of body conveying, in order that machine internal cavity sealing effectiveness is more preferable, liquid is prevented
Body or gas leak, usually pad has different sealing strip or sealing between mechanical fitting axially docks with mechanical fitting
Circle, mechanical link office can be made to reach internal cavity sealing, realize sealing and the conveying to liquid or gas.Such as to oil
It is required for carrying out sealing docking with gasket seal and sealing strip when pipeline and engine assembly, prevents junction poor sealing from causing
Gas leak of the oil leakage.Existing sealing strip uses homogenous material mostly, and such as rubber seal and rubber weather strip, rubber weather strip is logical
Over-pressed compression deformation reaches sealing machine device, and the rubber weather strip internal stress of homogenous material is bigger, after use easily
Aging, elastic after deformation to be deteriorated, service life is shorter, when particularly interface is sealed for the accessory of plane, with now
Capable sealing strip is easiest to occur deformed damaged and come off, so as to cause the problem of poorly sealed between mechanical fitting.Therefore have
Necessity proposes to improve.
Utility model content
The technical problem that the utility model solves：A kind of ellipse bipeltate compound sealing strip, the utility model are provided
Compound sealing strip is made using high elastic rubber and bipeltate, can effectively solve the problem that sealing strip made of existing homogenous material is deposited
Internal stress it is bigger, using deformation after elasticity be deteriorated, it is easy to aging, it is yielding damage come off, service life is short the problem of, its
Simple in construction, in light weight, manufacturing cost is low.
The technical solution adopted in the utility model：Ellipse bipeltate compound sealing strip, including high resiliency outer rubber layer,
The cross section I of the high resiliency outer rubber layer is ellipse, and the high resiliency outer rubber layer inside center is axially arranged with ellipse
Through hole, it is compound in the ellipse through hole to be provided with bipeltate.
Wherein, inside the full ellipse through hole of bipeltate filling, the cross section II of the bipeltate is and ellipse
Type through hole is adapted to the oval structure to be formed.
Further, the bipeltate is made of silastic material.
The utility model compared with prior art the advantages of：
1st, this programme be it is compound in high resiliency outer rubber layer be provided with foam rubbery material, make sealing strip have high resiliency,
The characteristics of high intensity, internal stress is small, compressible in size, and facial disfigurement is small on rear side of use, and anti-lateral extrusion is small, solves existing list
Internal stress existing for one material sealing strip is bigger, be deteriorated using elasticity after deformation, easy to aging, yielding damage comes off, used
The problem of short life, meet the requirement of mechanical device sealing well；
2nd, this programme uses two-layer composite, and its cross section is made into oval structure, not only has sealing strip
High resiliency and high non-deformability, and make gasket structure simple, easy to install and use, process for machining and manufacturing is simple, weight
Gently, manufacturing cost is low.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model；
Fig. 2 is structural front view of the present utility model；
Fig. 3 is Fig. 2 A-A to structure sectional view.
Embodiment
1-3 describes embodiment of the present utility model below in conjunction with the accompanying drawings.
Ellipse bipeltate compound sealing strip, as illustrated in fig. 1 and 2, including high resiliency outer rubber layer 1, the high resiliency
The cross section I 2 of outer rubber layer 1 is ellipse, as shown in figure 3, the inside center of high resiliency outer rubber layer 1 is axially arranged with ellipse
Type through hole 3, it is compound in the ellipse through hole 3 to be provided with bipeltate 4, specifically, the full ellipse of the filling of the bipeltate 4 is led to
Hole 3, the cross section II 5 of the bipeltate 4 are that the oval structure formed is adapted to ellipse through hole 3, it is preferred that the hair
Bubble rubber 4 is made of silicon rubber.
The utility model is compound in high resiliency outer rubber layer 1 to be provided with the material of bipeltate 4, has sealing strip high-elastic
Property, high intensity the characteristics of, internal stress is small, compressible in size, and facial disfigurement is small on rear side of use, and anti-lateral extrusion is small, solves existing
Have internal stress existing for homogenous material sealing strip it is bigger, using after deformation elasticity be deteriorated, it is easy to aging, it is yielding damage come off,
The problem of service life is short, meet the requirement of mechanical device sealing well；The utility model uses two-layer composite simultaneously,
And oval structure is made in sealing sliver transvers section, make sealing strip that not only there is high resiliency and high non-deformability, and make close
Strip of paper used for sealing is using easier for installation, and simple in construction, in light weight, manufacturing cost is low.
Above-described embodiment, simply preferred embodiment of the present utility model, not it is used for limiting the utility model practical range,
Therefore all equivalence changes done with content described in the utility model claims, the utility model claims model all should be included in
Within enclosing.
