Description
Technical field
The present invention relates to connection technical field of sealing technology, and in particular to a kind of seal for pipe joints mechanism being adapted to high pressure high fever.
Background technology
Pipeline is widely applied in production and life, pipeline and pipeline as transport liquid or the device of gas, or
Person's pipeline sealed connection device corresponding with the connection needs between container, in prior art, conventional mode is to be connect using rubber
Head or is directly connected by screw-thread fit water courage, is being run for a long time, especially under the bad working environments such as high pressure, high temperature,
Existing structure is easy gas leakage, insufficient to product air pressure, and product is easy layering, and production cost is excessively high, seriously affects product quality,
Invisible and huge use cost and loss can be caused to using the product by the user.
Invention content
Flange arrangement is used in view of the deficiencies of the prior art, the present invention proposes a kind of, and is provided with sealing on ring flange
Slot, sealing ring and seal boss cooperation, it is simple in structure, it is easy for installation, it is of low cost, it is with long service life to be adapted to high pressure high fever
Seal for pipe joints mechanism, specific technical solution is as follows：
A kind of seal for pipe joints mechanism being adapted to high pressure high fever, is provided with first flange disk (1) and second flange disk (2),
It is provided with pipeline connecting hole (3) in the middle part of the first flange disk (1), it is close to offer first around the pipeline connecting hole (3)
Circle mounting groove (4) is closed, the second closed circle mounting groove (5) is offered around the first closed circle mounting groove (4), it is second close to surround this
It closes circle mounting groove (5) and offers the closed circle mounting groove (6) of third, in the described first closed circle mounting groove (4), the second closed circle peace
It is both provided with closed circle (11) in tankage (5) and the closed circle mounting groove (6) of third；
It is provided with pipeline via (7) in the middle part of the second flange disk (2), the pipeline via (7) is centered around and is provided with
First closed (8) are provided with second closed (9) around first closed (8), are arranged around second closed (9)
There is fixing groove (10)；
The pipeline connecting hole (3), the first closed circle mounting groove (4), the second closed circle mounting groove (5) and the closed circle of third
Mounting groove (6) is oppositely arranged with the pipeline via (7), first closed (8), second closed (9) and fixing groove (10).
To better implement the present invention, further for：
The first closed circle mounting groove (4), the second closed circle mounting groove (5) and the closed circle mounting groove (6) of third are circle
Annular, and with pipeline connecting hole (3) concentric；
First closed (8), second closed (9) and fixing groove (10) be circular ring shape, and with the pipeline via
(7) concentric.Easy to process, seal is stronger.
The bottom of the first closed circle mounting groove (4), the second closed circle mounting groove (5) and the closed circle mounting groove (6) of third
Wall is arc-shaped, and even closer with the cooperation of closed circle (11), obturation effect is more preferable.
The height of first closed (8) is higher than described second closed (9).Step is formed, composition is multi-stage sealed,
In the case of one sealing ring failure, other sealing rings can work normally, and keep the sealing stability of total stronger.
Beneficial effects of the present invention are：1, closed circle mounting groove is opened up on ring flange, and there is fixed and limit to sealing ring
Position effect, during ensureing installation and use, closed circle will not be shifted because of the effect of external force and pressure, and obturation effect is caused to subtract
Weak or failure；2, the cooperation of closed be arranged on second flange disk and closed circle form multistage and are confined to, relative to normal
The plane of rule is contacted with sealing ring, and sealing effect greatly reinforces, and is more suitable for closed use under high temperature, hyperbaric environment；3, external
Using being bolted, convenient disassembly, service life is long, and manufacturing cost is cheap.
