Description
Technical field
The present invention relates to pipeline field, is a kind of slide-in type bellmouth pipe fitting, for welded still pipe socket joint connecting tube or with
Spiral welded steel pipe is 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 connected mode of pipeline, it connects
Binding structure is：Adjacent tubing inserts 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.The problem of existing be, the pipe fitting and tubing of prior art are usually be threadedly coupled, needs screw-in efficiency during installation
It is low；Also the mode for having socket joint to connect, although being advantageous 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, both easily produces center displacement, was subjected to again
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, and as pipe end lacks
Weary guiding is so as to damage sealing ring, after installation as the reason for crossing ellipsization, produces 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
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, a kind of slide-in type bellmouth pipe fitting of service life length.
The present invention solve technical problem scheme be：A kind of slide-in type bellmouth pipe fitting, it includes socket pipe, it is characterized in that：
Also include two guiding ring flat-plates, described two guiding ring flat-plates are respectively placed in the both ends of socket pipe, are oriented to the outer surface of ring flat-plate
Or one side end face be connected with socket pipe.
Described be oriented between the internal diameter size and tube outer diameter size and socket pipe internal diameter size of ring flat-plate has following relation：
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 use to be integrally formed or process respectively with socket pipe to be fixed with one again.
The bellmouth inside pipe wall sets at least two annular protrusions, for placing sealing ring.
At least two annular protrusions that the bellmouth inside pipe wall is set use and are integrally formed or annulus is placed in into socket pipe
Interior welding is fixed with one.
Attachment 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 present invention, the tradition for having abandoned the threaded connection that pipe fitting and tubing need to screw in connect
Method is connect, improves operating efficiency；The guiding ring flat-plate that its socket pipe is set not only increases bellmouth mouth of pipe intensity, ensure that bellmouth
The circularity of the mouth of pipe, and being oriented to when mounted to the socket of tubing, both beneficial to slide-in type bellmouth pipe fitting and tubing
Grafting is installed, and reduces the coaxial adjustment amount of adjacent preceding tubing, slide-in type bellmouth pipe fitting and rear tubing again, improves installation speed
Degree, it is ensured that gap uniformity between slide-in type bellmouth pipe fitting and tubing, and can change in outside environmental change and tube wall stress
When fetter caused center displacement between slide-in type bellmouth pipe fitting and tubing, improve sealing property, improve the stress shape of sealing ring
State, avoid sealing ring from bearing excessive load, extend sealing ring service life, reduce pipeline maintenance workload and into
This.The socket end of the bullet of equal pipe, the straight socket ovality of spiral welded pipe can be reduced.The present invention is applied to caliber φ
The pipelines of the test pressure within 4.0Mpa such as 159- φ 2020 oil, chemical industry, combustion gas, feedwater, draining, heat supply.With knot
The advantages that structure is simple, and sealing reliability is high, quick for installation, and repair demolition is convenient, and service life is long.
