Abstract
The invention provides an enhanced sealing ring, and relates to a sealing device. The inner side face of an outer enhanced ring (2) is provided with an inner side groove (6), the outer side face of an inner enhanced ring (1) is provided with an outer side groove (7), the inner side and the outer side of a rubber ring (5) are located in the outer side groove (7) in the inner enhanced ring (1) and the inner side groove (6) in the outer enhanced ring (2). The upper face and the lower face of the rubber ring (5) between the outer enhanced ring (2) and the inner enhanced ring (1) are provided with protruding pieces (3) respectively. According to the enhanced sealing ring, the inner edge and the outer edge of the rubber ring are wrapped with the inner enhanced ring and the outer enhanced ring respectively, the rubber ring is enhanced, and displacement caused by aging of the rubber ring is delayed effectively.
Description
[technical field]
The present invention relates to a kind of seal arrangement, be specifically related to a kind of enhancement mode seal ring.
[background technique]
Known, seal ring is all almost O shape structure, and cross section is the rubber ring of rectangular or circle, and seal ring is most popular a kind of Sealing in hydraulic pressure, pneumatic system.Seal ring has good sealing, both can be used for static seal, also can be used in reciprocating movement sealing; Not only can be used alone, and be element in many sealer with assembled, the seal ring of rectangular cross-sectional is used in equipment pipe or adpting flange, sealing is obtained by extruding, the basic functional principle of extrusion pressing type sealing relies on Sealing generation resiliently deformable, and sealing contact surface causes contact, and contact is greater than the interior pressure of sealed medium, then do not leak, otherwise then leak; But during due to liquid medium sealing to pipeline, because the reasons such as time can make rubber ring aging, occur further leaking, to be under pressure and displacement is ineffective.
[summary of the invention]
In order to overcome deficiency of the prior art, the invention discloses a kind of enhancement mode seal ring, in utilizing, enhancing circle and outer enhancing circle are by both sides parcel inside and outside rubber ring, obtain the enhancing of rubber ring, have effectively delayed the aging displacement brought of rubber ring.
In order to realize described goal of the invention, the present invention adopts following technology:
A kind of enhancement mode seal ring, comprise outer enhancing circle, rubber ring and interior enhancing circle, the inner side surface strengthening circle is outside provided with inner side slot, the interior outer side surface strengthening circle is provided with outer side slot, the inside and outside both sides of rubber ring are in interior enhancing in the outer side slot of circle and in the inner side slot of outer enhancing circle respectively, and described outer enhancing circle and interior enhancing on the rubber ring top and bottom between enclosing are respectively equipped with tabs.
Described enhancement mode seal ring, the tabs on rubber ring top and bottom is respectively equipped with at least two raised items.
Described enhancement mode seal ring, described outer enhancing circle is overall structure.
Described enhancement mode seal ring, the described interior random position strengthening circle is provided with gap.
Owing to have employed technique scheme, the present invention has following beneficial effect:
Enhancement mode seal ring of the present invention, enclosed by interior enhancing circle and outer enhancing and clamp inside and outside rubber ring, can limit that the transition of rubber ring under long-term high pressure " high temperature " environment is lax, displacement and aging, the tabs arranged in rubber ring top and bottom and raised item obtain the flexible guarantee of rubber ring; Structure of the present invention is simple, and user cost is lower.
[accompanying drawing explanation]
Fig. 1 is perspective view of the present invention;
Fig. 2 is assembly structure schematic diagram of the present invention;
Fig. 3 is structural representation of the present invention;
In figure: 1, interior enhancing circle; 2, outer enhancing circle; 3, tabs; 4, raised item; 5, rubber ring; 6, inner side slot; 7, outer side slot.
[embodiment]
With reference to the following examples, the present invention can be explained in more detail; But it should be noted that the present invention is not limited to following embodiment; Disclose object of the present invention to be intended to protect all changes and improvements in the scope of the invention.
By reference to the accompanying drawings 1, enhancement mode seal ring described in 2 or 3, comprise outer enhancing circle 2, rubber ring 5 and interior enhancing circle 1, described outer enhancing circle 2 is overall structure, the random position of described interior enhancing circle 1 is provided with the gap being convenient to install, the inner side surface strengthening circle 2 is outside provided with inner side slot 6, the outer side surface of interior enhancing circle 1 is provided with outer side slot 7, the inside and outside both sides of rubber ring 5 are in the outer side slot 7 of interior enhancing circle 1 respectively with in the inner side slot 6 of outer enhancing circle 2, rubber ring 5 top and bottom between described outer enhancing circle 2 and interior enhancing circle 1 are respectively equipped with tabs 3, the tabs 3 of described rubber ring 5 top and bottom is respectively equipped with at least two raised items 4.
Implement enhancement mode seal ring of the present invention, strengthening circle 1 and outer enhancing circle 2 in first making, wherein for the ease of installing, the wherein random position of interior enhancing circle 1 being arranged a gap; During installation, the outside of rubber ring 5 is first put into the inner side slot 6 of outer enhancing circle 2, then the gap strengthening circle 1 in utilizing will reduce, and be stuck in the inner side of rubber ring 5, clamped inside and outside rubber ring 5 by interior enhancing circle 1 and outer enhancing circle 2, the present invention is put between two adpting flanges, use bolt to fix two adpting flanges and just can; Use of the present invention can limit that the transition that rubber ring 5 occurs under long-term high pressure " high temperature " environment is lax, displacement and deterioration phenomenon.
Part not in the detailed description of the invention is prior art.
Claims (4)
1. an enhancement mode seal ring, comprise outer enhancing circle (2), rubber ring (5) and interior enhancing circle (1), it is characterized in that: the inner side surface strengthening circle (2) is outside provided with inner side slot (6), the interior outer side surface strengthening circle (1) is provided with outer side slot (7), the inside and outside both sides of rubber ring (5) are in that interior outer side slot (7) neutralization strengthening circle (1) is outer to be strengthened in the inner side slot (6) of circle (2) respectively, and described outer enhancing encloses (2) and interior enhancing on rubber ring (5) top and bottom enclosed between (1) is respectively equipped with tabs (3).
