Description
Technical field
The utility model is related to pipeline fields, are a kind of self-anchored type socket joint connecting tubes of automatic aligning, are used for welded still pipe
Socket joint connecting tube or using spiral welded steel pipe as the socket joint connecting steel plastic composite of base tube.
Background technology
Socket joint connection is that convenient and efficient, safe and efficient tubing connection type, the prior art are held in pipe installation process
Slotting connection is not applied only on cast iron pipe and concrete reinforced pipe, is also applied on welded still pipe, especially have been applied in
The isometrical steel pipe of spiral welded is on the steel-plastics composite pipe of base tube.One end of socket joint connecting tube is bellmouth, the other end is socket, phase
The socket of adjacent preceding socket joint connecting tube is plugged in the bellmouth of rear socket joint connecting tube, between sealing ring is set, to which socket joint be connected
It takes over and is tightly connected successively as pipeline.
The socket joint joint steel pipe or socket joint connecting steel plastic composite of the prior art, bellmouth are straight wall shape or horn-like, are deposited
In problems with：
1 since caliber is big, and size is long, and sealing intensity is big, so required power is larger when installation, grasp bellmouth and socket it
Between gap it is extremely difficult, often due to reason of expanding with heat and contract with cold, is easy that adjacent tubing dieback, the tubing after dieback is made to will produce
It heaves, there is security risks；
2 socket joint joint steel pipes or socket joint connecting steel plastic composite in heating network since material is heated in order to avoid generating
Steel pipe after heat expansion and dieback, which is led to the problem of, heaves etc. that there is security risks, it will usually be compensated using thermal compensator
Therefore the stroke of pipeline but increases the material cost and installation workload of pipeline, extends the set-up time, eventually lead to confession
The increase of the piping cost of hot pipe network；
Preceding socket joint connecting tube after 3 installations is difficult to adjust coaxial with rear socket joint connecting tube, leads to the slotting of preceding socket joint connecting tube
Gap is uneven between mouth and the bellmouth of rear socket joint connecting tube；As a result,：Preceding socket joint connecting tube is different from rear socket joint connecting tube
Axis increases the resistance that transmission medium flows in pipeline, and the pressure that tube wall is subject to is consequently increased, the socket of preceding socket joint connecting tube
The increase that gap is uneven between the bellmouth of rear socket joint connecting tube, tube wall is under pressure makes sealing ring locally bear load mistake
Greatly, center displacement is not only easy tod produce, but also is subjected to that load is excessive to be caused to fail, reduces sealing ring service life, increases pipeline
The workload and cost of repair, the bellmouth and socket ovality that existing spiral welded pipe is straight are larger, not only in the mistake of Pipe installing
Difficulty is increased in journey, and as pipe end lacks guiding to damage sealing ring, as crossing ellipsization after installation
The reason of, gap is uneven between generation tubing socket and pipe fitting, and so that sealing ring is locally born, load is excessive to be caused to reduce sealing
Effect.
4 socket joint joint steel pipes or socket joint connecting steel plastic composite be not due to having axial limitation, in pressure, vibrations, impact etc.
Under the influence of factor, the coupling part of socket joint is easy cracking and generates leakage, even takes off and pull out, to prevent the coupling part of socket joint to be easy
Cracking generates leakage, even takes off and pull out, and in directly buried pipeline mounting design, needs that fixing device is arranged, both increases design and system
The workload make, installed, and cost is increased, extend the set-up time.
