Description
【Technical field】
The present invention relates to a kind of soft sealer, and in particular to a kind of self-pressurization sealing ring.
【Background technology】
It is known, sealing of the sealing ring as pipeline joint, serve the work for preventing gas in pipelines or liquid leakage
With, because sealing ring is mostly rubber, ageing-resistant effect is poor, once the used time is long, poorly sealed phenomenon will occurs,
Existing processing mode be shut down change sealing ring, in the maintenance process of many industries, due to caused by shutdown operation into
This is high, and there is presently no preferable method to handle sealing ring problem of aging.
【The content of the invention】
In order to overcome deficiency of the prior art, the invention discloses a kind of self-pressurization sealing ring, the present invention utilizes pressurization
Chamber receives pipeline pressure the upper side of rubber seal and bottom surfaces is closely attached to pipeline joint, has effectively taken precautions against sealing
The generation of the leakage phenomenon occurred after circle ageing hardening.
In order to realize the goal of the invention, the present invention uses following technology：
A kind of self-pressurization sealing ring, including rubber seal and steel loop, it is provided around in the interior Middle face of rubber seal
Groove, the inside of the groove is provided with expanding pressurizing chamber, the pressurizing chamber and groove it is excessive down through step；On steel loop
It is even that multiple holes are distributed with；The steel loop is arranged in the pressurizing chamber in rubber seal ring recess, and the inner face up and down of the steel loop is withstood on
On the step of pressurizing chamber.
Described self-pressurization sealing ring, it is excessive that is, described that inclined-plane is provided between groove and the inwall of rubber seal
Notch is arranged to horn mouth.
Described self-pressurization sealing ring, the upper side and bottom surfaces of the rubber seal and the inner face of rubber seal,
Outside is arc-shaped transition.
Described self-pressurization sealing ring, steel loop is provided with the circle body between the pressurizing chamber and outer edge surface of rubber seal.
By adopting the above-described technical solution, the present invention has the advantages that：
Self-pressurization sealing ring of the present invention, it is expanding by being set in groove by setting groove in sealing ring inner face
Pressurizing chamber, ensure that sealing ring is indeformable by steel loop, receive pipeline pressure to make upper side and the bottom of rubber seal by pressurizing chamber
Face is closely attached to pipeline joint, has taken precautions against the generation of the leakage phenomenon occurred after sealing ring ageing hardening；Structure of the present invention
Simply, sealing effectiveness is substantially better than prior art.
【Brief description of the drawings】
Fig. 1 is the three-dimensional assembling structure schematic diagram of the present invention；
Fig. 2 is the structural representation of the present invention；
Fig. 3 is the assembling structure schematic diagram of the present invention；
In figure：1st, groove；2nd, rubber seal；3rd, hole；4th, steel loop；5th, horn mouth；6th, step；7th, pressurizing chamber；8th, steel loop.
【Embodiment】
With reference to the following examples, the present invention can be explained in greater detail；It should however be noted that not office of the invention
It is limited to following embodiments；The open purpose of the present invention is intended to protect all changes and improvements in the scope of the invention.
A kind of self-pressurization sealing ring with reference to described in accompanying drawing 1,2 or 3, including rubber seal 2 and steel loop 4, rubber seal
The upper side and bottom surfaces of circle 2 are arc-shaped transition with the inner face of rubber seal 2, outside, in the inner face of the rubber seal 2
The groove 1 that middle part is provided around, it is excessive to be provided with inclined-plane between groove 1 and the inwall of rubber seal 2, that is, 1 mouthful of the groove sets
Horn mouth 5 is set to, the inside of the groove 1 is provided with expanding pressurizing chamber 7, and the pressurizing chamber 7 is with groove 1 down through the mistake of step 6
Degree；Multiple holes 3 are evenly distributed with steel loop 4；The steel loop 4 is arranged in the pressurizing chamber 7 in the groove 1 of rubber seal 2, described
The inner face up and down of steel loop 4 is withstood on the step 6 of pressurizing chamber 7, the circle body between the pressurizing chamber 7 and outer edge surface of rubber seal 2
It is interior to be provided with steel loop 8.
Implement self-pressurization sealing ring of the present invention, one or two steel loops 8 are embedded in rubber in injection molded elastomer sealing ring
It is used to strengthen in glue sealing ring 2, the pressurizing chamber 7 in groove 1 and groove 1 is set in the inner face of rubber seal 2, then put steel loop 4
Enter in pressurizing chamber 7 and the inner face of the anchor ring up and down of steel loop 4 is withstood on the step 6 that pressurizing chamber 7 is excessively located with groove 1；Will during use
The present invention is placed between two adpting flanges of two pipelines, and two adpting flanges are fixedly connected with using bolt, when the gas in pipeline or
Liquid flow when, into pressurizing chamber 7 in the pressure of gas or liquid force pressurizing chamber 7 to be pressurized, received in synchronous pressurizing chamber 7
Pressure makes the upper side of rubber seal 2 and bottom surfaces closely be attached on the adpting flange interface of pipeline joint two so that
Rubber seal 2 can ensure not reveal always after ageing hardening.
Part not in the detailed description of the invention is prior art.
