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, and ellipse through hole is axially arranged with inside the high resiliency outer rubber layer, is combined in the ellipse through hole and is provided with bipeltate.The present invention is made compound sealing strip using high elastic rubber and bipeltate, can effectively solve the problem that internal stress that the rubber weather strip that existing homogenous material is made is present than it is larger, be deteriorated using elasticity after deformation, easily aging, yielding damage comes off, the problem that service life is short, its simple structure, it is easy to install and use, it is lightweight, low cost of manufacture.
Description
Technical field
The invention belongs to mechanical seal device manufacturing technology field, and in particular to a kind of ellipse bipeltate compound seal
Bar.
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 more preferably, prevents liquid
Body or gas leak, usually pad has different sealing strip or sealing between mechanical fitting is axially docked with mechanical fitting
Circle, can make mechanical link office reach internal cavity and seal, and realize the sealing and conveying to liquid or gas.For example 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, such as rubber seal and rubber weather strip mostly, and rubber weather strip is logical
Over-pressed compression deformation reaches sealing machine device, and the rubber weather strip internal stress of homogenous material is than larger, after use easily
Aging, elasticity is deteriorated after deformation, and service life is shorter, particularly interface for the accessory of plane sealed when, with existing
Capable sealing strip is easiest to occur deformed damaged and comes off, so as to cause poorly sealed problem between mechanical fitting.Therefore have
Necessity proposes to improve.
The content of the invention
Present invention solves the technical problem that：A kind of ellipse bipeltate compound sealing strip is provided, the present invention is using high-elastic
Property rubber and bipeltate be made compound sealing strip, can effectively solve the problem that the planted agent that the sealing strip that existing homogenous material is made is present
Power than it is larger, using after deformation elasticity be deteriorated, easily it is aging, it is yielding damage come off, the problem that service life is short, its structure letter
It is single, lightweight, low cost of manufacture.
The technical solution adopted by the present invention：Ellipse bipeltate compound sealing strip, including high resiliency outer rubber layer, it is described
The cross section I of 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 combined in the ellipse through hole and is 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.
Present invention advantage compared with prior art：
1st, this programme be in high resiliency outer rubber layer be combined 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 use rear side facial disfigurement is small, and anti-lateral extrusion is small, solves existing list
The internal stress that one material sealing strip is present than it is larger, be deteriorated using elasticity after deformation, easily aging, yielding damage comes off, uses
The problem of short life, meets 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 non-deformability high, and make gasket structure simple, easy to install and use, process for machining and manufacturing is simple, weight
Gently, low cost of manufacture.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the invention；
Fig. 2 is structural front view of the invention；
Fig. 3 is the A-A of Fig. 2 to structure sectional view.
Specific embodiment
1-3 describes embodiments of the invention 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, is combined in the ellipse through hole 3 and is 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 is that the oval structure for being formed is adapted to ellipse through hole 3, it is preferred that the hair
Bubble rubber 4 is made of silicon rubber.
The present invention is combined in high resiliency outer rubber layer 1 and is provided with the material of bipeltate 4, sealing strip is had high resiliency, height
The characteristics of intensity, internal stress is small, compressible in size, and use rear side facial disfigurement is small, and anti-lateral extrusion is small, solves existing single
The internal stress that material sealing strip is present than it is larger, be deteriorated using elasticity after deformation, easily aging, yielding damage comes off, uses the longevity
The short problem of life, meets the requirement of mechanical device sealing well；The present invention uses two-layer composite simultaneously, and by sealing strip
Cross section is made oval structure, sealing strip is not only had high resiliency and non-deformability high, and sealing strip is used peace
Dress more facilitates, and simple structure is lightweight, low cost of manufacture.
Above-described embodiment, simply presently preferred embodiments of the present invention, not for limiting the scope of the present invention, thus it is all with this
The equivalence changes that content described in invention claim is done, all should be included within scope of the invention as claimed.
