Abstract
The invention discloses a kind of new type silicone rubber sealing ring, the first arc-shaped protrusions are provided with the top of the gusset of the silicone rubber O-ring, the arc-shaped protrusions of gusset bottom second of the silicone rubber O-ring, enclosed in the silicone rubber O-ring provided with annular projection, oil sealing chamber is formed between adjacent annular projection, annular hollow out net is provided with described annular projection, the silicone rubber O-ring is made of silastic material.The beneficial effects of the invention are as follows：Silicone rubber O-ring utilizes two arc-shaped protrusions of outer surface so that this silicone rubber O-ring need not indicate use direction, facilitate the use of user；The bulk strength that silicone rubber O-ring is strengthened after annular hollow out net is added in annular projection, anti-pressure ability is good, and toughness is high, the good sealing effect in complex environment；Silicone rubber O-ring can greatly improve the oil sealing ability of whole silicone rubber O-ring using the oil sealing chamber of inner surface.
Description
Technical field
The present invention relates to silicon rubber loop design field, particularly a kind of new type silicone rubber sealing ring.
Background technology
Silicon rubber refers to that main chain is alternately made up of silicon and oxygen atom, and the rubber of two organic groups is generally connected with silicon atom.Common silicon rubber is mainly made up of the silica chain link containing methyl and a small amount of vinyl.The introducing of phenyl can improve the high- and low-temperature resistance performance of silicon rubber, and the introducing of trifluoro propyl and cyano group can then improve the heatproof and oil resistance of silicon rubber.Silicon rubber resistance to low temperature is good, typically remains to work at -55 DEG C.After introducing phenyl, reachable -73 DEG C.The heat resistance of silicon rubber is also very prominent, at 180 DEG C can long-term work, a little higher than 200 DEG C can also bear several weeks or longer time it is still flexible, be instantaneously resistant to more than 300 DEG C of high temperature.
In general rubber seal can be used in static seal occasion, prominent sealing function is shown, but in dynamic appropriate occasion, rubber seal is limited by the speed at sealing and pressure, requirement to sealing ring is higher, and common rubber seal is difficult to reach requirement.
The content of the invention
Based on this, in view of the above-mentioned problems, being necessary to propose a kind of new type silicone rubber sealing ring, the silicone rubber O-ring good toughness, intensity is high, good airproof performance.
The technical scheme is that：A kind of new type silicone rubber sealing ring, the first arc-shaped protrusions are provided with the top of the gusset of the silicone rubber O-ring, the arc-shaped protrusions of gusset bottom second of the silicone rubber O-ring, enclosed in the silicone rubber O-ring provided with annular projection, oil sealing chamber is formed between adjacent annular projection, annular hollow out net is provided with described annular projection.
The silicone rubber O-ring of the present invention utilizes two arc-shaped protrusions of outer surface, so that this silicone rubber O-ring need not indicate use direction, facilitate the use of user, the bulk strength that silicone rubber O-ring is strengthened after annular hollow out net is added in annular projection, anti-pressure ability is good, and toughness is high, the good sealing effect in complex environment, meanwhile silicone rubber O-ring can greatly improve the oil sealing ability of whole silicone rubber O-ring using the oil sealing chamber of inner surface.
Preferably, described annular projection is placed equidistant in described silicone rubber O-ring.
Preferably, the arc radius and arc of the first described arc-shaped protrusions and the second arc-shaped protrusions are highly identical.
Preferably, described annular hollow out net and annular projection concentric are set.
The beneficial effects of the invention are as follows：
（1）Silicone rubber O-ring utilizes two arc-shaped protrusions of outer surface so that this silicone rubber O-ring need not indicate use direction, facilitate the use of user；
（2）The bulk strength that silicone rubber O-ring is strengthened after annular hollow out net is added in annular projection, anti-pressure ability is good, and toughness is high, the good sealing effect in complex environment；
（3）Silicone rubber O-ring can greatly improve the oil sealing ability of whole silicone rubber O-ring using the oil sealing chamber of inner surface；
（4）Distribution of force is uniform when the annular projection and annular hollow out net being uniformly arranged cause silicone rubber O-ring stress, can prevent local premature breakdown, increase the service life.
