Description
Technical field
The present invention relates to pipeline field, is that one kind slips into self-anchored type socket joint connecting tube, and the socket joint for welded still pipe connects
Pipe or the socket joint connecting steel plastic composite using spiral welded steel pipe as base tube.
Background technology
Socket joint connection is convenient and swift, safe and efficient tubing connected mode in Pipe installing, and the socket joint of prior art connects
Connect and be not applied only on cast iron pipe and concrete reinforced pipe, be also applied on welded still pipe, especially have been applied in spiral
The isometrical steel pipe of welding is on the steel-plastics composite pipe of base tube.One end of socket joint connecting tube is bellmouth, the other end is socket, adjacent
The socket of preceding socket joint connecting tube is plugged in the bellmouth of rear socket joint connecting tube, between sealing ring is set, so as to by socket joint connecting tube
It is pipeline to be tightly connected successively.
The socket joint joint steel pipe or socket joint connecting steel plastic composite of prior art, its bellmouth are straight wall shape or horn-like, are deposited
In problems with：
1 because caliber is big, and size length, sealing intensity is big, so required power is larger during installation, grasp bellmouth and socket it
Between gap it is extremely difficult, often due to reason of expanding with heat and contract with cold, easily make adjacent tubing dieback, the tubing after dieback can produce
Heave, there is potential safety hazard；
2 socket joint joint steel pipes or socket joint connecting steel plastic composite in heating network because material is heated in order to avoid producing
Steel pipe after heat expansion, and dieback, which produces, heaves etc. that there is the problem of potential safety hazard, it will usually is compensated using thermal compensator
The stroke of pipeline, the material cost and installation workload of pipeline are but therefore added, the set-up time is extended, ultimately results in confession
The increase of the piping cost of hot pipe network；
Preceding socket joint connecting tube and rear socket joint connecting tube after 3 installations are difficult to that adjustment is coaxial, cause the slotting of preceding socket joint connecting tube
Gap is uneven between mouth and the bellmouth of rear socket joint connecting tube；The result is that：Preceding socket joint connecting tube is different from rear socket joint connecting tube
Axle 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 both easily produced, is subjected to that load is excessive to be caused to fail again, reduces sealing ring service life, increases pipeline
The workload and cost of maintenance, the bellmouth and socket ovality that existing spiral welded pipe is straight are larger, not only in the mistake of Pipe installing
Difficulty is added in journey, and as pipe end lacks guiding so as to damage sealing ring, as crossing ellipsization after installation
The reason for, gap is uneven between generation tubing socket and pipe fitting, and 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 are due to no axially limitation, in pressure, vibrations, impact etc.
Under the influence of factor, the coupling part of socket joint easily ftractures and produces leakage, even takes off and pull out, to prevent the coupling part of socket joint easy
Cracking produces leakage, even takes off and pull out, it is necessary to set fixing device in directly buried pipeline mounting design, has both added design and system
The workload make, installed, adds cost again, extends the set-up time.
The content of the invention
The technical problems to be solved by the invention are：The shortcomings that overcoming prior art, there is provided a kind of simple in construction, sealing can
It is high by property, it is quick for installation, it is easy to adjust, repair demolition is convenient, and one kind of service life length slips into self-anchored type socket joint connecting tube.
The present invention solve technical problem scheme be：One kind slips into self-anchored type socket joint connecting tube, including equal pipe and bellmouth,
One end of the equal pipe is socket, the other end is connection end, and one end of the bellmouth is the small end of necking down, the other end of bellmouth
For big end, the small end of bellmouth and the connection end of equal pipe are connected, it is characterized in that：The grappling for also including having concurrently limiting anchoring function is convex
Edge and the guiding grappling ring flat-plate for having guiding grappling function concurrently, the anchor flanges are socketed in the socket end of equal pipe and are connected, institute
State and be oriented to the big end that grappling ring flat-plate is placed in bellmouth, be oriented to a side end face of grappling ring flat-plate and the big end of bellmouth is connected, be oriented to grappling
Ring flat-plate be located at the inner peripheral surface in the big end of bellmouth be spigot surface, the part on the outside of the big end of bellmouth be anchor plate.
Described be oriented between the internal diameter size and socket outside dimension and bellmouth internal diameter size of grappling ring flat-plate has with ShiShimonoseki
System：
D ＜ D ＜ D1 ⑴
In formula：D --- socket outside dimension；D --- it is oriented to the internal diameter size of grappling ring flat-plate；D1--- bellmouth internal diameter chi
It is very little.
The inner peripheral surface for being oriented to grappling ring flat-plate sets boot segment.
The boot segment for being oriented to grappling ring flat-plate is arc surface or taper surface.
The bellmouth inwall sets at least one of annular protrusion, for placing the first sealing ring.
At least one of annular protrusion that the bellmouth inside pipe wall is set, which uses, to be integrally formed or annulus is placed in into socket pipe
Interior welding is fixed with one.
The socket end of the equal pipe sets jack tube and is connected.
The socket end of the equal pipe is straight socket or tapered spigot, and the cone angle of its tapered spigot is 20 °~24 °
The equal pipe is spiral welded steel pipe or straight seam welded steel pipe.
