Abstract
The utility model relates to a tetrafluoroethylene coated rubber O-shaped ring widely used for various industries, such as, pressure vessels for the chemical industry, mechanical seals, conduit wiring joints, aerospace, power equipment, machinery for food industry, etc. The utility model belongs to the technical field of sealing devices. The utility model mainly adopts a tetrafluoroethylene coating layer coated outside the rubber O-shaped ring and makes the tetrafluoroethylene coating layer and the rubber O-shaped ring be an integration. The fractal surface (a transition layer) of the outside of the tetrafluoroethylene coating layer is 90-180 DEG. The thickness is 0.15-0.5 mm. The structure of the utility model is compact and reasonable. No butt line is equipped at the circumference of the tetrafluoroethylene coating layer. The thickness is homogeneous and the using performance is stable. When applied, the utility model can not contact the medium to generate chemical reaction. The outside of the utility model is provided with chemical resistance of tetrafluoroethylene. The performance is provided with ultra-low friction coefficient and wear resistance which is more than 50 times bigger than that of rubber. The utility model is provided with elasticity of fluoroelastomer, silicon rubber and nitrile rubber and long sealed memorability. The utility model can ensure that the composite 'O-shaped' ring is provided with excellent compressing and rebounce performance.
Description
Technical field
The utility model relates to the rubber-coated O shape circle of a kind of tetrafluoroethylene, is widely used in industries such as pressure vessels for the chemical industry, mechanical seal, pipe joint, Aero-Space, power equipment and food machinery, belongs to the seal assemblies technical field.
Background technique
Before the utility model was made, in prior art, simple rubber o-ring can not adapt to the technical requirementss such as high speed, high temperature, high burn into long-life of machinery in modern age along with the development of The modern industry.In addition, simple rubber ring easily takes place aging, and working life is short, needs often to change, and therefore needs to increase user cost.
Technology contents
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of compact structure is provided, rationally; The glue core is coated fully by tetrafluoro, can not contact with medium during application and chemical reaction takes place, corrosion-resistant, heatproof, flexible, wear resistance is strong, and the rubber-coated O shape circle of tetrafluoroethylene of ultra-low friction coefficient is arranged.
Main solution of the present utility model is achieved in that
The utility model mainly adopts tetrafluoro clad 2 to be coated on outside the rubber o-ring 1, and tetrafluoro clad 2 outside fractal areas 3 are 90-180 °.Tetrafluoro clad 2 thickness are 0.15-0.5mm.
Compared with the prior art the utility model has the following advantages:
The utility model compact structure, rationally; Tetrafluoro clad circumference does not have seam and thickness is even, and usability is stable; Can not contact during application and chemical reaction takes place with medium; Its outside has the chemical resistance of tetrafluoro, and performance has ultralow friction factor, and has the wear resistance that surpasses 50 times of rubber; The elasticity that has fluorine rubber, silicone rubber, Nitrile Rubber has permanent sealing Memorability, guarantees that compound round section joint ring has excellent compression recovery performance.
