Abstract
The utility model provides a kind of high-elastic locking washer, comprise sleeve pipe, sleeve pipe has preset thickness, and its inner surface is provided with the annular groove with multiple sawtooth, be filled with foam material in annular groove, in foam material, be provided with the skeleton of two annular carbon fibre composite materials.The utility model passes through at sleeve pipe filled with foaming material inside, not only improve the elasticity of seal ring, simultaneously cost-saving, annular groove in sleeve pipe can prevent foam material and sleeve pipe from misplacing, and the skeleton of the carbon fibre composite material in foam material can the intensity of enhanced leaktightness circle, prevents the generation of phenomenon of rupture, in addition, flexible silicon glue-line and elastomeric skin layer can strengthen the elasticity of seal ring further, improve the quality of seal ring, extend the working life of seal ring.Simple, cheap, reliable and stable being easy to again of the utility model favorable sealing property, structure realizes.
Description
Technical field
The utility model relates to technical field of sealing technology, and specifically, the utility model relates to a kind of high-elastic locking washer.
Background technique
In the equipment such as various machinery, chemical industry, metallurgy, in order to prevent the seepage of liquids and gases, need at equipment interface, and suitable place providing effective sealing, for this reason, generally adopting seal ring, sealing gasket etc. are as the most basic sealing original paper.Because seal ring usually works under rugged environment, so necessarily require seal ring to have anticorrosive, anti-high and low-temp, the outstanding sealability such as wear-resistant, guarantee sealing effect is good for a long time and reliable and stable.
The single constructive layer seal ring that seal ring of the prior art generally adopts solids elastomeric material to make, the elasticity being usually expressed as seal ring is poor, easily occurs phenomenon of rupture simultaneously.For the problems referred to above, those skilled in the art need badly provides a kind of Novel high-elasticity seal ring.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of high-elastic locking washer, not only improves the elasticity of seal ring, prevents seal ring from rupturing simultaneously.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of high-elastic locking washer, comprise sleeve pipe, described sleeve pipe has preset thickness, and its inner surface is provided with the annular groove with multiple sawtooth, be filled with foam material in described annular groove, in described foam material, be provided with the skeleton of two annular carbon fibre composite materials.
Preferably, described outside of sleeve wall is provided with flexible silicon glue-line.
Preferably, the outside of described flexible silicon glue-line is coated with elastomeric skin layer.
Preferably, described seal ring is structure as a whole, and is bondd between described flexible silicon glue-line and described elastomeric skin layer by sulfuration.
Preferably, the outside of described seal ring is provided with receiving groove seal ring being expanded when being subject to gas or fluid pressure.
Preferably, the sawtooth of the annular groove on described sleeve pipe inner surface is triangular sawtooth.
Preferably, the sawtooth of the annular groove on described sleeve pipe inner surface is rectangular saw-tooth.
Preferably, the material of described sleeve pipe is rubber.
The utility model provides a kind of high-elastic locking washer, by at sleeve pipe filled with foaming material inside, not only improve the elasticity of seal ring, simultaneously cost-saving, the annular groove in sleeve pipe can prevent foam material and sleeve pipe from misplacing, the skeleton of the carbon fibre composite material in foam material can the intensity of enhanced leaktightness circle, prevent the generation of phenomenon of rupture, in addition, flexible silicon glue-line and elastomeric skin layer can strengthen the elasticity of seal ring further, improve the quality of seal ring, extend the working life of seal ring.Simple, cheap, reliable and stable being easy to again of the utility model favorable sealing property, structure realizes.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of high-elastic locking washer preferred embodiment of the present utility model.
[in figure reference character]:
10. sleeve pipe, 20. annular grooves, 30. foam materials, 40. skeletons, 50. flexible silicon glue-lines, 60. elastomeric skin layer, 70. receiving grooves.
Embodiment
For making content of the present utility model clearly understandable, below in conjunction with Figure of description, content of the present utility model is described further.Certain the utility model is not limited to this specific embodiment, and the general replacement known by those skilled in the art is also encompassed in protection domain of the present utility model.Secondly, the utility model detailed statement that utilized schematic diagram to carry out, when describing the utility model example in detail, for convenience of explanation, schematic diagram, should in this, as to restriction of the present utility model not according to general ratio partial enlargement.
Above-mentioned and other technical characteristics and beneficial effect, will in conjunction with the embodiments and accompanying drawing 1 high-elastic locking washer of the present utility model is described in detail.As shown in Figure 1, Fig. 1 is the structural representation of high-elastic locking washer preferred embodiment of the present utility model.
As shown in Figure 1, the utility model provides a kind of high-elastic locking washer, comprise sleeve pipe 10, sleeve pipe 10 has preset thickness, and its inner surface is provided with the annular groove 20 with multiple sawtooth, be filled with foam material 30 in annular groove 20, in foam material 30, be provided with the skeleton 40 of two annular carbon fibre composite materials.
In order to improve the elasticity of seal ring further, sleeve pipe 10 outer side wall is provided with flexible silicon glue-line 50, meanwhile, also can be coated with elastomeric skin layer 60 in the outside of flexible silicon glue-line 50.Preferably, seal ring is structure as a whole, and is bondd between flexible silicon glue-line 50 and elastomeric skin layer 60 by sulfuration, and the material of sleeve pipe 10 is preferably rubber.
In addition, the outside of seal ring also can be provided with the receiving groove 70 seal ring being expanded when being subject to gas or fluid pressure, and receiving groove 70 can further improve the sealability of seal ring.
