Description
Technical field
The utility model is related to pipeline fields, are a kind of slide-in type bellmouth pipe fittings, socket joint connecting tube for welded still pipe,
Or using spiral welded steel pipe as the connection of the socket joint connecting steel plastic composite of base tube.
Background technology
In Pipe installing, tubing is in turn connected to form by pipeline by pipe fitting, is one of connection mode of pipeline, connected
Binding structure is：Adjacent tubing is inserted into pipe fitting respectively from the both ends of pipe fitting, between sealing ring is set, so that tubing be sealed successively
It is connected as pipeline.There are the problem of be that the pipe fitting of the prior art and tubing are usually is threadedly coupled, when installation, needs screw-in efficiency
It is low；Also the mode for having socket joint to connect, although being conducive to install, is difficult to adjust between the preceding tubing, pipe fitting and rear tubing after installation
It is whole coaxial, cause gap between pipe fitting and tubing uneven, the result is that：It is not coaxial between preceding tubing, pipe fitting and rear tubing
The resistance that transmission medium in pipeline flows is increased, the pressure that tube wall is subject to is consequently increased, and gap is not between pipe fitting and tubing
Uniformly, the increase that tube wall is under pressure makes sealing ring locally bear load excessive, not only easily generates center displacement, but also is subjected to
Load is excessive to be caused to fail, and reduces sealing ring service life, increases the workload and cost of pipeline maintenance, and existing spiral welded pipe is put down
Straight bellmouth and socket ovality is larger, difficulty is not only added during Pipe installing, but also as pipe end lacks
Weary guiding is so as to damage sealing ring, after installation as the reason for crossing ellipsization, generates between tubing socket and pipe fitting gap not
Uniformly, sealing ring is made locally to bear the excessive effect for causing to reduce sealing of load.
The content of the invention
Technical problem to be solved in the utility model is：The shortcomings that overcoming the prior art, provide it is a kind of simple in structure, it is close
It is high to seal reliability, it is quick for installation, it is easy to adjust, repair demolition is convenient, a kind of slide-in type bellmouth pipe fitting of service life length.
The utility model solve technical problem scheme be：A kind of slide-in type bellmouth pipe fitting, it includes socket pipe, feature
It is：Two guiding ring flat-plates are further included, described two guiding ring flat-plates are respectively placed in the both ends of socket pipe, are oriented to the outer weekly form of ring flat-plate
Face or a side end face are connected with socket pipe.
There is following relation between the guiding internal diameter size of ring flat-plate and tube outer diameter size and socket pipe internal diameter size：
D ＜ D ＜ D1 ⑴
In formula：D --- tube outer diameter size；D --- it is oriented to the internal diameter size of ring flat-plate；D1--- socket pipe internal diameter size.
The inner peripheral surface for being oriented to ring flat-plate sets boot segment.
The boot segment for being oriented to ring flat-plate is arc surface or taper surface.
Described two guiding ring flat-plates are used to be integrally formed or process respectively with socket pipe and are fixed with one again.
The bellmouth inside pipe wall sets at least two annular protrusions, for placing sealing ring.
Annulus using integrated molding or is placed in socket pipe by least two annular protrusions that the bellmouth inside pipe wall is set
Interior welding is fixed with one.
Connection structure between adjacent preceding tubing, slide-in type bellmouth pipe fitting and rear tubing is：The preceding tubing is plugged on
The front end of slide-in type bellmouth pipe fitting, rear tubing are plugged on the rear end of slide-in type bellmouth pipe fitting, preceding tubing and slide-in type bellmouth pipe fitting,
It is respectively in sealing contact by the sealing ring set in socket pipe between tubing and slide-in type bellmouth pipe fitting afterwards.
The sealing ring is T-shaped sealing ring.
A kind of slide-in type bellmouth pipe fitting of the utility model has abandoned the biography for the threaded connection that pipe fitting is screwed in tubing needs
System connection method, improves work efficiency；The guiding ring flat-plate that its socket pipe is set not only increases bellmouth nozzle intensity, ensure that
The circularity of bellmouth nozzle, and the socket of tubing can be oriented to when mounted, both beneficial to slide-in type bellmouth pipe fitting and pipe
The grafting installation of material, and reduce the coaxial adjustment amount of adjacent preceding tubing, slide-in type bellmouth pipe fitting and rear tubing, improve peace
Fill speed, it is ensured that gap uniformity between slide-in type bellmouth pipe fitting and tubing, and can be in external environmental change and tube wall stress
The center displacement generated between slide-in type bellmouth pipe fitting and tubing is fettered during variation, improve sealing performance, improve sealing ring by
Power state avoids sealing ring from bearing excessive load, extends sealing ring service life, reduce pipeline maintenance workload and
Cost.The socket end of the bullet of equal pipe can reduce the straight socket ovality of spiral welded pipe.The utility model is suitable for
The pipelines of the test pressures within 4.0Mpa such as oil, chemical industry, combustion gas, feedwater, draining, the heat supply of caliber φ 159- φ 2020.
It is high with simple structure and reliable sealing, quick for installation, the advantages that repair demolition is convenient, and service life is long.
