Abstract
The utility model discloses an O-shaped ring for vacuum cambered sealing. The O-shaped ring for vacuum cambered sealing is characterized by comprising a cambered steel frame, wherein an integral cambered rubber ring is vulcanized outside the cambered steel frame and is matched with a to-be-sealed camber in shape, positioning bumps are distributed on the installation matching end face of the cambered rubber ring, and inclined seal convex ribs are axially distributed on the edge of an inner ring of the cambered rubber ring. The O-shaped ring for vacuum cambered sealing disclosed by the utility model is reasonable in structural design, overcomes the deficiency of conventional O-shaped rings on cambered sealing, and has the characteristics of reliable sealing, convenience in installation and positioning, good stability and the like. Meanwhile, the O-shaped ring for vacuum cambered sealing is completely applicable to vacuum sealing environments by adopting a modified fluorinated silicone rubber material.
Description
Technical field
The utility model relates to a kind of O type coil structures, relates in particular to the O type circle of curved surface sealing for a kind of vacuum.
Background technique
In vacuum seal, except having rational structure, select elastomeric material more crucial.The auxiliary seal ring of mechanical seal mostly is rubber o-ring, and this is because can utilize larger compressibility that low hardness or medium-hard rubber are strengthened to its distortion, so that rubber ring more can be fitted fully by the gap on Sealing surface, improves sealability.Traditional O type circle for curved surface static seal, all with common substituting for radial and axial static seal O type circle, causes O type circle when sealing curved surface like this, yielding, easily extrudes.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and the O type circle of a kind of vacuum with curved surface sealing is provided.
The utility model is achieved through the following technical solutions:
The O type circle of curved surface sealing for a kind of vacuum, it is characterized in that: include curved surface Steel Skeleton, the outer sulfuration of described curved surface Steel Skeleton has the curved surface rubber ring of one, curved surface rubber ring coordinates with curve form to be sealed, on the installation counterface of described curved surface rubber ring, be distributed with positioning convex, the inner ring edge of described curved surface rubber ring is provided with the inclination seal bead of axial distribution.
Described curved surface rubber ring adopts modified fluoro-silicone rubber material ，Qie Qi inner ring edge to be distributed with circular orientation boss.
The utility model adopts curved surface O type circle, substitute traditional O type circle, the shape of the curved surface of sealing, according to the shape of curved surface, produces the O type circle of the curve form of fitting completely as required, such sealing is reliable, coordinate positioning convex and circular orientation boss simultaneously, can increase and the fitment stability that need to seal curved surface, location is installed conveniently, by the structure of inclination seal bead, increase its sealability.Overcome the shortcoming of traditional O type circle in curved surface sealing.And adopt modified fluoro-silicone rubber material, this material have low permeability and apply in a vacuum, seldom hide gas feature, be applicable to completely in vacuum-packed environment.
The utility model has the advantages that:
The utility model reasonable in design, has overcome the shortcoming of traditional O type circle in curved surface sealing, has sealing reliable, and installation location is convenient, and the features such as good stability adopt modified fluoro-silicone rubber material simultaneously, can be applicable to completely in vacuum-packed environment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cross section structure schematic diagram.
Embodiment
Referring to accompanying drawing, the O type circle of curved surface sealing for a kind of vacuum, include curved surface Steel Skeleton 1, the outer sulfuration of curved surface Steel Skeleton 1 has the curved surface rubber ring 2 of one, curved surface rubber ring 2 coordinates with curve form to be sealed, on the installation counterface of curved surface rubber ring 2, be distributed with positioning convex 3, the inner ring edge of curved surface rubber ring 2 is provided with the inclination seal bead 4 of axial distribution.Described curved surface rubber ring 2 adopts modified fluoro-silicone rubber material ，Qie Qi inner ring edge to be distributed with circular orientation boss 5.
Claims (2)
