Abstract
The utility model provides a kind of seal ring, belongs to seal fitting technical field.It is low that it has solved existing seal ring sealing intensity, easily produce distortion, and sealing effect is poor, increases maintenance cost, affects the problem of working efficiency in the time that pressure is high.This seal ring comprises inner and outer wall, the little flue in large one end, inwall one end, seal ring is provided with by one end end face the rubber ring that the eyelet of protuberance and one end end face be provided with recess and forms, eyelet and rubber ring are by described protuberance and recess snap-fit, and on inwall, eyelet part internal diameter is more than or equal to the internal diameter of rubber ring part.This seal ring is little by large one end, seal ring inwall one end is set, and heavy caliber end is feed-water end, small-caliber end is waterexit end, thereby make the pressure between small-caliber end and component increase increase sealing effect by fluid impact heavy caliber end, and heavy caliber end is metal end, has therefore increased sealing intensity.
Description
Technical field
The invention belongs to seal fitting technical field, relate to a kind of seal ring.
Background technique
In mechanical field, between a lot of parts, need seal ring to seal.The seal ring adopting is at present to be all generally made up of rubber, because intensity is low, easily produces distortion in the time that pressure is high, makes sealing effect poor, increases maintenance cost, affects working efficiency.
Existing seal ring cross section is circular in addition, is a kind of beidirectional Sealing.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, a kind of good sealing effect is provided, the seal ring that easy for installation and life-span is long.
Object of the present invention can realize by following technical proposal: a kind of seal ring, comprise inner and outer wall, the described little flue in large one end, inwall one end, it is characterized in that: described seal ring is provided with by one end end face the rubber ring that the eyelet of protuberance and one end end face be provided with recess and forms, described eyelet and rubber ring are by described protuberance and recess snap-fit, and on described inwall, eyelet part internal diameter is more than or equal to the internal diameter of rubber ring part.
In above-mentioned seal ring, on described outer wall, rubber ring part has annular the first groove).
In above-mentioned seal ring, described rubber ring inside is also provided with circular ring metal skeleton.
In above-mentioned seal ring, described rubber ring is provided with annular the second groove away from one end end face of eyelet, the second described groove axle center and rubber ring axle center overlaid.
In above-mentioned seal ring, described eyelet outer wrap copper sheet.
In above-mentioned seal ring, described metal frame cross section is that circle and diameter are 0.20-0.40mm.
In above-mentioned seal ring, described eyelet surface is through polishing treatment.
In above-mentioned seal ring, described seal ring is shaped as O shape, triangle, rectangle, trapezoidal, X-shaped, Y shape.
Compared with prior art, tool of the present invention has the following advantages:
1, large one end, seal ring inwall one end is set little, and heavy caliber end is feed-water end, small-caliber end is waterexit end, thereby makes the pressure between small-caliber end and component increase increase sealing effect by fluid impact heavy caliber end, and heavy caliber end is metal end, has therefore increased sealing intensity.
2, heavy caliber feed-water end is eyelet, thereby also plays erosion-resisting effect at eyelet outer wrap copper sheet strengthening in intensity, improves product working life.
3, due to the easy deformation of rubber ring, therefore sealing circle can adapt to be arranged in different sealing groove, and seal ring is shaped as O shape, triangle, rectangle, trapezoidal, X-shaped, Y shape, therefore easier for installation.
4, by being also provided with endless metal skeleton in rubber ring inside, more increased the intensity of seal ring.
5, rubber ring is provided with annular the second groove away from one end end face of eyelet, if fluid flow in annular the second groove, due to annular the second groove axle center and rubber ring axle center overlaid, therefore fluid forms uniform pressure and also can make seal ring sealing effect better in annular the second groove.
