Description
Technical field
The utility model relates to mechanical sealing element technical field, is specifically related to a kind of oil filter sealing gasket.
Background technique
Gasket seal, as long as be a kind ofly have for machinery, equipment, pipeline the sealing spare part that the place of fluid is exactly, uses inside and outside, the material sealed.Gasket seal is with metal or nonmetal tabular material, and through cutting, the technique such as punching press or cutting is made, for being tightly connected between pipeline, and being tightly connected between the parts of machinery equipment and parts.Metallic packing and nonmetal gasket seal can be divided into by material.Metal have copper backing, stainless steel gasket, iron gasket, aluminium backing etc.Nonmetallic have asbestos washer, non-asbestos pad, paper gasket, rubber sheet gasket etc.But the gasket structure in the market for oil filter is more single, sealing is paid somebody's debt and expected repayment later does not have shock-proof pressure-tight effect.If Chinese application number is that CN 203051760 U discloses a kind of gasket seal, this pad is when carrying out end face seal, simple technique can be utilized just can to realize sealing function, there is good vibration resistance simultaneously, and be applicable to the working environment that fluid pressure is higher, but the sealing gasket of this technology does not have good, elasticity and rebound elasticity, sealing gasket easily damages in generation resiliently deformable, and durability is not high.
Model utility content
The purpose of this utility model is to provide a kind of oil filter sealing gasket, to solve the above-mentioned multinomial defect caused in prior art.
A kind of oil filter sealing gasket, comprise metal gasket outer ring, rubber gasket and fixed hole, described metal gasket outer ring is identical with the shape of rubber gasket, it is inner that described rubber gasket is fixedly bonded in metal gasket outer ring, rubber gasket surface is provided with by the compound strip of strip, described compound strip comprises metal tape and nonmetal, metal tape and non-metallic are spaced spiral and roll and to form and in circular, described non-metallic has projection along the rolling of rubber gasket length direction, protruding outside the annulus of rubber gasket, described fixed hole is arranged on above metal gasket outer ring, the number of fixed hole is 8, in equidistant annular array.
Preferably, described rubber gasket has carried out polishing smoothing processing, and the outer surface plane degree of rubber gasket is 0.002-0.003mm.
Preferably, described metal tape is the metal tape prepared by stainless steel.
Preferably, described non-metallic is the non-metallic prepared by flexible nonmetal material.
Preferably, the cross section of described non-metallic in " V " type, and is arranged symmetrically with along the center line of rubber gasket length direction.
The utility model has the advantage of: there is good, elasticity and rebound elasticity, intensity is high, not fragile; When rubber gasket two ends are squeezed the masterpiece used time, rubber gasket produces resiliently deformable, contacts more tight, favorable sealing property with to be sealed; When it is subject to the fluctuating load of working environment generation, can carry out good sealing compensation, shock resistance is good; Rubber gasket can reach good sealing effect under less extruding force effect, and installation capability is good, long service life; Compared with pure nonmetallic gasket, it is not easy to produce plastic deformation and stress relaxation, has the stability of long term seal, simple technique can be utilized just can to realize sealing function, there is good vibration resistance simultaneously, and be applicable to the higher working environment of fluid pressure.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil filter sealing gasket described in the utility model.
Fig. 2 is the plan view of the compound strip of a kind of oil filter sealing gasket described in the utility model.
Wherein: 1-metal gasket outer ring, 2-rubber gasket, 21-compound strip, 211-metal tape, 212-non-metallic, 3-fixed hole.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of oil filter sealing gasket, comprise metal gasket outer ring 1, rubber gasket 2 and fixed hole 3, described metal gasket outer ring 1 is identical with the shape of rubber gasket 2, it is inner that described rubber gasket 2 is fixedly bonded in metal gasket outer ring 1, rubber gasket 2 surface is provided with the compound strip 21 by strip, described compound strip 21 comprises metal tape 211 and nonmetal 212, metal tape 211 and non-metallic 212 are spaced spiral and roll and to form and in circular, described nonmetal 212 bands have projection along the rolling of rubber gasket 2 length direction, protruding outside the annulus of rubber gasket 2, described fixed hole 2 is arranged on above metal gasket outer ring 1, the number of fixed hole 3 is 8, in equidistant annular array, have good, elasticity and rebound elasticity, intensity is high, not fragile, when rubber gasket 2 two ends are squeezed the masterpiece used time, rubber gasket 2 produces resiliently deformable, contacts more tight, favorable sealing property with to be sealed, when it is subject to the fluctuating load of working environment generation, can carry out good sealing compensation, shock resistance is good, rubber gasket 2 can reach good sealing effect under less extruding force effect, and installation capability is good, long service life, compared with pure nonmetallic gasket, it is not easy to produce plastic deformation and stress relaxation, has the stability of long term seal, simple technique can be utilized just can to realize sealing function, there is good vibration resistance simultaneously, and be applicable to the higher working environment of fluid pressure.
It should be noted that described rubber gasket 2 has carried out polishing smoothing processing, the outer surface plane degree of rubber gasket 2 is 0.002-0.003mm, and rubber gasket 2 sealing effect of this technique is better, and outer surface is comparatively smooth.
