Abstract
The invention provides a high-elasticity sealing ring which comprises a sleeve. The sleeve has the preset thickness. An annular groove provided with a plurality of saw-teeth is formed in the surface of the inner side of the sleeve and filled with foaming materials. Two annular skeletons made of carbon fiber composite materials are arranged in the foaming materials. As the sleeve is filled with the foaming materials, the elasticity of the sealing ring is improved, and cost is saved; the annular groove in the sleeve can prevent mismatching of the foaming materials and the sleeve, the skeletons, made of the carbon fiber composite materials, in the foaming materials can enhance the strength of the sealing ring, and the fracture phenomenon is prevented; in addition, an elastic silica gel layer and a rubber skin layer can enhance the elasticity of the sealing ring, the quality of the sealing ring is improved, and the service life of the sealing ring is prolonged. The sealing ring is good in sealing performance, simple in structure, low in price, stable, reliable and easy to obtain.
Description
Technical field
The present invention relates to technical field of sealing technology, specifically, the present invention 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.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of high-elastic locking washer, not only improves the elasticity of seal ring, prevents seal ring from rupturing simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: 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 invention 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 favorable sealing property of the present invention, structure realizes.
