Abstract
The utility model discloses a high elasticity tetrafluorated coating rubber O-shaped obturating ring with the cross section of a tetrafluorated bushing (1) coating a rubber strip (2). The utility model is characterized in that the rubber strip (2) is a hollow rubber strip with the cross section in a shape of circle and square or in a shape of upper semi-circle and lower rectangle spliced together with the connecting sides being taken out. The high elasticity tetrafluorated coating rubber O-shaped obturating ring has the advantages of strong inoxidability and fireresistant property as well as cryophylactic property, good rebound resilience and sealability, ideal sealing effect and long service life.
Description
Technical field
The utility model relates to the seal element that prevents the liquids and gases seepage in a kind of equipment that is widely used in industries such as machinery, chemical industry, metallurgy, food, pharmacy, Aero-Space, boats and ships, specifically is the rubber-coated ○Xing Mifengquan of a kind of high elasticity tetrafluoro.
Background technique
Simple rubber seal since far can not satisfy the modern industry high-corrosion resistant, just, temperature, at a high speed wearing and tearing, need the technical requirements of long-life and progressively be eliminated.
China national intellectual property board web discloses a kind of seal ring and rubber-coated ○Xing Mifengquan of a kind of tetrafluoro with composite double layer structure, two kinds of seal rings by the entity rubber strip of internal layer be coated on outer field tetrafluoro sleeve pipe and form.Because PTFE such as tetrafluoroethylene---hexafluoropropylene copolymer (fluoroplastic 46) itself has excellent chemical property, so these two kinds of seal ring corrosion resistances are strong, high-and low-temperature resistance and wear resistance are strong.But there is following common deficiency in these two kinds of seal rings, and promptly the elastic index of seal ring is still undesirable is that compression recovery performance is not too strong, still undesirable as the excellent sealing performance that seal ring at first should possess, and directly influences the sealing effect of these two kinds of seal rings; And the manufacturing process of preceding a kind of seal ring is relatively complicated, and manufacture cost is high relatively; Then a kind of seal ring is not because entity (heart) rubber strip has the expansionary force of nature, so the adhesive strength of entity rubber strip and tetrafluoro sleeve pipe is not ideal.
The seal ring of above-mentioned prior art also has a common shortcoming, and the shape of its cross section only has circular a kind of, can not satisfy the specific (special) requirements that some has the equipment of special-shaped sealed cavity shape.
The model utility content
The technical problems to be solved in the utility model is, overcome the shortcoming of above prior art, provide a kind of both corrosion resistances strong, high-and low-temperature resistance and wear resistance are strong, has good rebound elasticity again, the rubber-coated ○Xing Mifengquan of high elasticity tetrafluoro of its sealability excellence, sealing effect ideal and long service life.
Technical solution of the present utility model is, a kind of rubber-coated ○Xing Mifengquan of high elasticity tetrafluoro with following structure is provided, and its cross section is rubber-coated of a tetrafluoro sleeve pipe, and described rubber strip is the hollow rubber bar, and promptly the center of rubber strip is the hole.
After adopting above structure, the rubber-coated ○Xing Mifengquan of the utility model high elasticity tetrafluoro compared with prior art has the following advantages:
Since the rubber-coated ○Xing Mifengquan of this high elasticity tetrafluoro still by the rubber strip of internal layer be coated on outer field tetrafluoro sleeve pipe and form, because PTFE such as tetrafluoroethylene---hexafluoropropylene copolymer (fluoroplastic 46) itself has excellent chemical property, as characteristics such as anti-height, warm nature energy, fire retardant, chemical stability, flame retardant propertys, so, it is strong that this seal ring has still kept above two kinds of seal ring corrosion resistances, the advantage that high-and low-temperature resistance and wear resistance are strong.
Simultaneously, because this seal ring has adopted the hollow rubber bar, the center that is rubber strip is the hole, overcome the common deficiency that above two kinds of prior art seal rings exist fully, make the elastic index of seal ring obtain desirable lifting, the compression resilience that is seal ring is very strong, possesses excellent sealing ability, and its sealing effect is splendid.Compare with preceding a kind of seal ring, the outer tetrafluoro sleeve pipe of this seal ring adopts conventional expressing technique to make, and the internal layer of seal ring adopts hollow fluorine rubber bar or hollow silicon rubber bar, adopts to produce in batches, and its manufacturing process is simple, and manufacture cost is lower.Compare with a kind of seal ring in back, because this seal ring hollow rubber bar has the expansionary force of nature, so, the adhesive strength ideal of hollow rubber bar and tetrafluoro sleeve pipe.
As improvement, its cross section can be circle, also can be squarely, also can be and removes shape that fillet forms etc. after first circular and following rectangular amalgamation.Like this, can satisfy the specific (special) requirements that some has the equipment of special-shaped sealed cavity shape, make the applicable surface of this seal ring wider.
