Description
Technical field
The utility model relates to pipeline connection neck more particularly to a kind of inflatable seal cushion rubbers for pipeline connection.
Background technique
Pipeline is that pumped (conveying) medium is most quick, cheap and reliable method, and natural gas and water, petroleum etc. can pass through pipeline
To convey.With the development of economy, the usage amount of pipeline is more and more, and caliber is also increasing.The interconnection technique of pipeline is to pipe
The laying construction process in road or the sealing effect of conveyance conduit suffer from very important influence, and existing pipeline connection type is not
Have a several ways such as flanged joint, welding, socket joint outside, but these connection types all have the defects that it is certain.Wherein flange connects
Connecing with socket joint connection request pipeline itself there is flange or bell and spigot to be just able to achieve connection, and require in welding manner identical
The pipeline of material is just able to achieve connection, these connection types require all pipelines to be connected and meet specific condition, commonly
Pipeline is difficult to realize the connection of pipeline when not having these conditions, is in addition sealed just with common sealing rubber ring,
Sealing effect is also bad, very inconvenient in actual operation.
Summary of the invention
The purpose of this utility model is that: it is full that all pipelines to be connected are required for above-mentioned existing pipeline connection type
The phenomenon that foot specific condition, caused common pipe was difficult to realize the problem of pipeline connects, this reality when not having these conditions
A kind of inflatable seal cushion rubber for pipeline connection is provided with novel.
The technical solution adopted in the utility model is as follows:
A kind of inflatable seal cushion rubber for pipeline connection, including exterior seal ring and interior sealing rubber ring, further include air bag,
Air inlet pipe and clamping flange, the interior sealing rubber ring are arranged in two common pipe junctions, the outer layer of the interior sealing rubber ring
Be provided with air bag, the air bag outer layer is provided with the adjustable exterior seal ring of internal diameter, is provided with air inlet pipe on the air bag, it is described into
Tracheae passes through and is fixed on exterior seal ring, and the open end of the air inlet pipe is provided with sealing-plug, the exterior seal ring both ends difference
It is provided with clamping flange, each clamping flange is fixed by fishbolt, and the exterior seal ring is hatch frame, described outer
The setting of sealing ring one end is fluted, and the other end setting of the exterior seal ring extends in fluted.
Working principle:
The two first common pipes for needing to connect screw in interior sealing rubber ring, sealing-plug are then removed, then toward air bag
Interior sealing rubber ring is compressed in interior pump gas, air bag air-blowing, and interior sealing rubber ring radially inward deformation, internal diameter reduces, to tightly bind round
Then the air inlet seal of tube is played sealing function with sealing-plug by firmly connected common pipe, then will be clamped with fishbolt
Flange is fixedly connected, and the part that clamping flange makes exterior seal ring extend to groove increases, and exterior seal ring internal diameter becomes smaller, and squeezes gas
Capsule, air bag act on interior sealing rubber ring, make that two common pipes connected is needed more to fasten, the utility model structure letter
Effect single, easy for installation, sealing effect is good, structure novel are practical.
Further, the exterior seal ring welds together or is integrally formed with clamping flange, can both make inflatable seal
Cushion rubber manufacture is more easier, and common pipe connection can be made more firm.
Further, the both ends of the exterior seal ring are respectively arranged with 2-4 clamping flange, can make inflatable seal glue
The better tightness of circle, it is not easily to fall off.
Further, the outer radius of the common pipe is respectively less than exterior seal ring maximum inside radius, and two common pipes half
Diameter can be different, and the common pipe that can operate with different radii keeps inflatable seal cushion rubber application range wider.
Further, annular dimpled grain is set on the inner sidewall of the interior sealing rubber ring, in receiving air sac pressing rearward recess
Air is discharged, and is close to tube wall, is increased the difficulty removed, keep interior sealing rubber ring more not easily to fall off.
Further, it is provided with a non-return valve in the air inlet pipe and is fixedly connected with exterior seal ring, becomes air inlet pipe
One-way air inlet, air bag terminate to become flat after pumping gas, are conducive to the sealing of air bag.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the utility model has achieved the effect that structure is simple, easy for installation, sealing effect is good, structure novel, practicability
By force；
2. making the manufacture of inflatable seal cushion rubber more by the way that exterior seal ring is welded together or is integrally formed with clamping flange
It is easy to add, and common pipe connection can be made more firm；
3. can be more preferable with inflatable seal rubber sealing by setting clamping flange, it is not easily to fall off；
4. can operate with the common pipe of different radii by using air bag, make inflatable seal cushion rubber application range more
Extensively；
5. annular dimpled grain is set on the inner sidewall of sealing rubber ring in, so that interior sealing rubber ring is close to tube wall, increases the difficulty removed
Degree, it is more not easily to fall off.
