Abstract
The utility model discloses a composite sealing ring which is dynamically sealed. The composite sealing ring comprises a sealing ring body (3); the rotational sealing combination surface of the sealing ring body (3) is provided with a group of barbs (6); the statically sealed surface of the sealing ring body (3) is provided with an annular groove (5) which is internally provided with an O-shaped rubber ring (4) so as to form the composite sealing ring together. On one hand, the barbs of the dynamically sealed surface enhance the reliability of sealing; on the other hand, the O-shaped rubber ring is adopted for assisting in static sealing, thus prolonging service life.
Description
Technical field
The utility model relates to seal ring, is specifically related to realize the compound seal ring of rotary dynamic seal.
Background technique
At present, mechanical industry generally adopts the seal ring of rubber ring as rotary dynamic seal, and its material is a General Purpose Rubber, and friction factor is big, and working life is short, and it is unreliable to seal.
Summary of the invention
The purpose of this utility model is: a kind of compound seal ring of motive sealing is provided, and this compound seal ring sealing is reliable, long service life.
Technical solution of the present utility model is: this compound seal ring comprises the seal ring body, establish one group of hangnail at the rotary seal junction plane of seal ring body, static seal face at the seal ring body is established circular groove, places O shape rubber ring in the circular groove, the compound seal ring of whole formation.
The utility model hangnail of motive sealing face has on the one hand strengthened the reliability that seals, and adopts the O rubber ring to assist static seal on the other hand, increases the service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 solid of rotation, 2 matrixes, 3 seal ring bodies, 4O shape rubber ring, 5 circular grooves, 6 hangnails
Embodiment
As shown in Figure 1, this compound seal ring comprises seal ring body 3, establishes one group of hangnail 6 at the rotary seal junction plane of seal ring body 3, establishes circular groove 5 at the static seal face of seal ring body 3, place O shape rubber ring 4 in the circular groove 5, the compound seal ring of whole formation.
During use, compound seal ring is installed between solid of rotation 1 and matrix 2, solid of rotation 1 is the sealing surface of rotary dynamic seal with the surface of contact of seal ring body 3, pressure enters from the bottom, hangnail 6 is being embraced under the effect of pressure on the solid of rotation 1 of portion within it tightly, make its sealing reliable, O shape rubber ring 4 keeps good static seal with the matrix 2 and the seal ring body 3 of seal ring body 3 outsides effectively.
Claims (1)
1. the compound seal ring of motive sealing, it is characterized in that: this compound seal ring comprises seal ring body (3), establish one group of hangnail (6) at the rotary seal junction plane of seal ring body (3), establish circular groove (5) at the static seal face of seal ring body (3), place O shape rubber ring (4) in the circular groove (5), the compound seal ring of whole formation.
