Turn.In other words, it is greater than the of socket tube body 201 relative to the width of the concave tooth of first kind annular projection 104 on bellmouth tube body 101
The width of two class annular projections 204 is greater than bellmouth relative to the concave tooth width of the second class annular projection 204 on socket tube body 201
The width of the first kind annular projection 104 of tube body 101, therefore bellmouth tube body 101 and socket tube body 201 are completed after assembling, first
There is gap between class annular projection 104 and the second class annular projection 204.
There can also be contact gap between the planomural section of bellmouth tube body 101 and the planomural section of socket tube body 201, so that interface
It can deflect.
Fig. 7 B shows bellmouth tube body and socket tube body with the interface cross section schematic diagram after low-angle α deflection.
In the embodiment shown in Fig. 7 A and 7B, the section shape of first kind annular projection 104 and the second class annular projection 204
Shape is triangle, however the protection scope of the utility model is not limited thereto, first kind annular projection 104 and the second class annular projection
204 section shape can also be trapezoidal or semicircle.
The self-locking bell and spigot of this kind of flexible sealing according to the present utility model and method is accepted, is processed using on bellmouth structure
First kind annular protrusion, processing can form the second class convex annular of self-locking installation with first kind annular protrusion in outlet structure
It rises, increases sealing ring sealing, outlet structure alignment bellmouth structure is then subjected to extruding installation, wherein after being installed, first
Between class annular protrusion and the second class annular protrusion have a fixed gap, enable installation after bell and spigot small angle deflection,
Such as 0-3 degree, better adaptability.Bellmouth and jack part increase planomural section, are more convenient installation.In tube coupling installation, new tubulature
It is more to save pluggable socket section, facilitates counterpart, sealing is realized in the contact by planomural section with sealing ring.It can also increase in planomural section
Contact gap deflects interface.By first kind annular protrusion and the second class annular protrusion, bell and spigot is realized self-locking and inclined
Turn, differential settlement can be better adapted to.
Double containment bell socket disclosed by the utility model and undertaking method are strong with 1) pipeline connection integrity, after connection
It can not separate；2) pipe joint anti-pulling can be used for drawing jacking construction；3) pipeline connects good leak tightness, and sealing performance is excellent；
4) pipeline is easy to connect, and quickly, an interface can complete connection in 2 minutes for construction；5) pipe joint is without in-flanges；6) it manages
Space needed for pipeline joint is small, and tool is simple；7) the advantages that at low cost.
In the embodiment shown in figure 7 above A and 7B, the shape of first kind annular protrusion and the second class annular protrusion is mutual
It mends, and after completing assembly, first kind annular protrusion and the second class annular protrusion have a fixed gap along pipe axis.However this field
Technical staff should be realized that the protection scope of the utility model is not limited thereto, first kind annular protrusion and the second class convex annular
The shape risen can not be complementary shape, as long as being installed rear first kind annular protrusion and the second class annular protrusion can form certainly
It locks and there is gap between the two, enable bellmouth and socket with respect to small angle deflection, should just fall into the protection of the utility model
Range.
In some embodiments of the utility model, first kind annular protrusion and/or second described in the utility model
Class annular protrusion can also be curved protrusion.
In a particular application, bellmouth disclosed by the utility model and/or outlet structure can be also used for other pipelines, example
Such as, PE is managed into manufactured bell and spigot and is welded to other tubing.For example, bell and spigot made of can managing PE is welded to internal-rib enhancing
On pipe, Hollow wall tube or double-wall corrugated pipe.
Although described above is each embodiments of the utility model, however, it is to be understood that they are intended only as example to be in
Existing, and without limitation.For those skilled in the relevant art it is readily apparent that various combinations, change can be made to it
Type and the spirit and scope changed without departing from the utility model.Therefore, the width and model of the utility model disclosed herein
Enclosing should not be limited by above-mentioned disclosed exemplary embodiment, and should be according only to the appended claims and its equivalent replacement
To define.
