Description
[technical field]
This utility model relates to the welding structure of a kind of composite metal-plastic pipe material and plastic socket pipe fitting, belongs to
In technical field of pipeline connection.
[background technology]
China Patent No. CN202065674 U discloses the bent of the non-maintaining application of a kind of whole process and plays vector structure
Tubing, connects pipe fitting 2 and has lengthening section 7 (see Fig. 3), and main body tubing 1 has outer tube 4 (see figure
2), after connection pipe fitting 2 is connected with both main body tubing 1 as shown in Figure 4: connect the lengthening of pipe fitting 2
There is gap between section 7 inwalls and the outer tube 4 of main body tubing 1, the existence in this gap is by unconquerable
Cause the metal end contact fluid of this main body tubing 1, so that the metal end face of this main body tubing 1
Corrode and form " tearing cloth effect ", cause the problem that tubing multiple structure destroys.
Elsewhere, impact is connected the bonding strength of pipe fitting 2 and main body tubing 1 by the existence in gap.
[utility model content]
Deficiency that this utility model exists for above-mentioned prior art and a kind of composite metal-plastic pipe material is provided
Welding structure with plastic socket pipe fitting.
For solving above-mentioned technical problem, this utility model following technical scheme of offer:
Composite metal-plastic pipe material and the welding structure of plastic socket pipe fitting, including composite metal-plastic pipe material
With the plastic socket pipe fitting of the described composite metal-plastic pipe material of connection, described composite metal-plastic pipe material has
Outer plastic pipe layer, interior plastic pipe layer and the metal tube layer being compound between this two tube layer, multiple at this metallo-plastic
The front end closing tubing is formed with the naked section of interior plastic pipe layer, and described plastic socket pipe fitting has at least two
Connection connection end, and at least one connect end be shaped with socket joint main paragraph, be positioned at outside this socket joint main paragraph
Socket joint extension and be positioned at the oncus section inside this socket joint main paragraph, at composite metal-plastic pipe material
During with plastic socket pipe fitting hot melt grafting, the naked section of composite metal-plastic pipe material, outer plastic pipe layer are respectively
Socket joint main paragraph, socket joint extension hot-melt adhesive paste with plastic socket pipe fitting.
As supplementing technique scheme and perfect, this utility model can also use skill in detail below
Art measure:
The wall thickness of the outer plastic pipe layer of above-mentioned composite metal-plastic pipe material is less than the wall thickness of interior plastic pipe layer.
The internal diameter of plastic socket pipe fitting position, wall thick section within it and the internal diameter one of composite metal-plastic pipe material
Cause.
Pipe fitting internal diameter is consistent with pipe internal diameter, in junction not undergauge, do not produce flow resistance, do not affect pipeline
Flow.
Composite metal-plastic pipe material inserts the outer plastic pipe layer length of plastic socket pipe fitting less than exposed segment length
Degree.
Compared with prior art, this utility model has the advantage that and beneficial effect:
After composite metal-plastic pipe material and plastic socket pipe fitting hot melt grafting, the socket joint of plastic socket pipe fitting prolongs
The section of stretching achieves frit seal with the outer plastic pipe layer of composite metal-plastic pipe material, has thus stopped this tubing
End contact fluid, thus avoid metal tube layer and occur that end face corrodes, it is to avoid tubing multiple structure destroys
The generation of phenomenon, and the heat seal strength of composite metal-plastic pipe material and plastic socket pipe fitting is strengthened.
