Abstract
The invention relates to a soft sealing device, in particular to a self-pressurization sealing ring. A surrounding groove (1) is formed in the middle of the inner face of a rubber sealing ring (2). A hole enlargement pressurization cavity (7) is formed inside the groove (1). The upper and lower portions of the pressurization cavity (7) are in transition with the upper and lower portions of the groove (1) through steps (6). A plurality of holes (3) are evenly formed in a steel ring (4). The steel ring (4) is arranged in the pressurization cavity (7) inside the groove (1) in the rubber sealing ring (2). The inner upper and lower faces of the steel ring (4) abut against the steps (6) of the pressurization cavity (7). According to the self-pressurization sealing ring, the groove is formed in the inner face of the sealing ring, the hole enlargement pressurization cavity is formed inside the groove, it is ensured that the sealing ring does not deform through the steel ring, the upper face and the lower face of the rubber sealing ring are tightly attached to the butt-joint position of the pipeline due to the fact that the pressurization cavity absorbs pipeline pressure, and the leakage phenomenon occurring after the sealing ring is aged and hardened is prevented.
Description
[technical field]
The present invention relates to a kind of soft seal device, be specifically related to a kind of self-pressurization seal ring.
[background technique]
Known; seal ring is as the sealing of pipeline joint; serve the effect preventing gas in pipelines or leak of liquid, because seal ring is mostly rubber product, ageing-resistant effect is poor; once the used time is long; just there will be poorly sealed phenomenon, existing processing mode shuts down to change seal ring, in the maintenance process of a lot of industry; high owing to shutting down the operation cost brought, also there is no good method process seal ring problem of aging at present.
[summary of the invention]
In order to overcome deficiency of the prior art, the invention discloses a kind of self-pressurization seal ring, the present invention utilizes pressurizing chamber to receive pipeline pressure to make the upper side of rubber seal and bottom surfaces be attached to pipeline joint closely, the generation of the leakage phenomenon occurred after effectively having taken precautions against seal ring ageing hardening.
In order to realize described goal of the invention, the present invention adopts following technology:
A kind of self-pressurization seal ring, comprises rubber seal and steel loop, in rubber seal Middle face be provided with around groove, the inside of described groove is provided with expanding pressurizing chamber, described pressurizing chamber and groove excessive down through step; Steel loop is evenly distributed with multiple hole; Described steel loop is arranged in the pressurizing chamber in rubber seal ring recess, and the inner face up and down of described steel loop withstands on the step of pressurizing chamber.
Described self-pressurization seal ring, between groove and the inwall of rubber seal, be provided with inclined-plane excessive, namely described notch is set to horn mouth.
Described self-pressurization seal ring, the inner face of the upper side of described rubber seal and bottom surfaces and rubber seal, outside are arc-shaped transition.
Described self-pressurization seal ring, is provided with steel loop in the circle body between the pressurizing chamber and outer edge surface of rubber seal.
Owing to have employed technique scheme, the present invention has following beneficial effect:
Self-pressurization seal ring of the present invention, by arranging groove at seal ring inner face, by arranging expanding pressurizing chamber in groove, guarantee that seal ring is indeformable by steel loop, pipeline pressure is received to make the upper side of rubber seal and bottom surfaces be attached to pipeline joint closely by pressurizing chamber, the generation of the leakage phenomenon occurred after having taken precautions against seal ring ageing hardening; Structure of the present invention is simple, and sealing effect is obviously better than prior art.

Fig. 2 is structural representation of the present invention;
Fig. 3 is assembly structure schematic diagram of the present invention;
In figure: 1, groove; 2, rubber seal; 3, hole; 4, steel loop; 5, horn mouth; 6, step; 7, pressurizing chamber; 8, steel loop.
[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.
A kind of self-pressurization seal ring by reference to the accompanying drawings described in 1,2 or 3, comprise rubber seal 2 and steel loop 4, the inner face of the upper side of rubber seal 2 and bottom surfaces and rubber seal 2, outside are arc-shaped transition, in described rubber seal 2 Middle face be provided with around groove 1, inclined-plane is provided with excessive between groove 1 and the inwall of rubber seal 2, namely described groove 1 mouthful is set to horn mouth 5, the inside of described groove 1 is provided with expanding pressurizing chamber 7, and described pressurizing chamber 7 is excessive down through step 6 with groove 1; Steel loop 4 is evenly distributed with multiple hole 3; Described steel loop 4 is arranged in the pressurizing chamber 7 in rubber seal 2 groove 1, and the inner face up and down of described steel loop 4 withstands on the step 6 of pressurizing chamber 7, in the circle body between the pressurizing chamber 7 and outer edge surface of rubber seal 2, be provided with steel loop 8.
Implement self-pressurization seal ring of the present invention, when injection molded elastomer seal ring, one or two steel loops 8 are embedded in rubber seal 2 and be used for strengthening, pressurizing chamber 7 in groove 1 and groove 1 is set at the inner face of rubber seal 2, then steel loop 4 is put into pressurizing chamber 7 and make the inner face of the anchor ring up and down of steel loop 4 withstand on pressurizing chamber 7 with on the excessive step 6 located of groove 1; Between two adpting flanges during use, the present invention being placed on two pipelines, bolt is used to be fixedly connected with two adpting flanges, when the gas in pipeline or flow of fluid, the pressure entering gas or liquid in pressurizing chamber 7 forces pressurizing chamber 7 supercharging, the pressure received in synchronous pressurizing chamber 7 makes the upper side of rubber seal 2 and bottom surfaces be attached to closely on pipeline joint two adpting flange interface, makes rubber seal 2 can ensure not reveal after ageing hardening always.
Part not in the detailed description of the invention is prior art.
