Description
【Technical field】
The utility model belongs to technical field of pipeline connection, and in particular to a kind of composite metal plastic pipe with identification ring.
【Background technology】
It needs that steel-plastic composite pressure pipe material and plastic pipe are first subject to tight grafting before usual composite metal plastic pipe welding, two
Row electromagnetic welding again after person's grafting, and whether welding can not only know with observation in appearance, can inevitably be deposited in pipeline sometimes
In steel-plastic composite pressure pipe material and plastic pipe without welding, it there is also that weldment and non-weldment be (but tightly sometimes
Grafting) fish mesh the problem of mixing.
【Utility model content】
The utility model provides a kind of steel-plastics composite pipe with identification ring in view of the deficiency of the prior art
Road.
In order to solve the above technical problems, the utility model provides the following technical solutions：
Composite metal plastic pipe with identification ring, including steel-plastic composite pressure pipe material, plastic pipe and identification ring, steel modeling are multiple
Resultant pressure tubing has outer plastic pipe layer, intermediate steel pipe layer and interior plastic pipe layer, the connecting pin for connection that there are two plastic pipe tools,
Each connecting pin is formed with an outer portion, an internal ring portion and the cyclic annular socket joint chamber being formed between outer portion and internal ring portion, steel modeling
Composite pressure tubing is inserted in cyclic annular socket joint chamber, and identification ring is equipped between outer plastic pipe layer and outer portion, and forms in identification
The flange of ring end and the end face of outer portion are inconsistent, and improvement is in steel-plastic composite pressure pipe material and plastic pipe welding
When, the flange of identification ring and the end face of outer portion generate gap.
The wall of its port of outer portion is in circular conical surface, and identification ring is to assign in the port of outer portion, and identification ring is interior
Wall is adapted with the surface of outer plastic pipe layer, and the conical surface of identification ring is adapted with the wall of its port of outer portion.
The inner wall of identification ring is matched with the surface of outer plastic pipe layer, and the conical surface of identification ring and its end of outer portion
The wall of mouth is adapted, and identification ring can be moved promptly relative to outside plastic pipe when being so conducive to plugging position melting, and outer shifting is suitable
Freely, resistance is small, once welding forms above-mentioned gap.
Compared with prior art, the utility model has the following advantages that and advantageous effect：
Before welding, the end face of identification ring and outer portion is inconsistent, and after welding, identification ring is produced with the end face of outer portion
Gap, the presence or absence of gap, can recognize that whether already welding is connect steel-plastic composite pressure pipe material with plastic pipe, identification ring is known accordingly
Other function is eye-catching thus is fully able to accurate judgement without obscuring, and avoids the negative consequence caused by leaking welding.
【Description of the drawings】
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the cross-sectional view of the structure of the utility model；
Fig. 2 is the structure chart of the plastic pipe of the utility model；
Fig. 3 is that steel-plastic composite pressure pipe material, identification ring are planted to the schematic diagram (welding being installed on plastic pipe respectively
Before).
【Specific implementation mode】
It please refers to Fig.1, shown in 2,3, carries the composite metal plastic pipe of identification ring, including steel-plastic composite pressure pipe material 1, plastics
Pipe fitting 2 and identification ring 3, steel-plastic composite pressure pipe material 1 have outer plastic pipe layer 11, intermediate steel pipe layer 12 and interior plastic pipe layer 13,
There are two the connecting pins being connected to for the tool of plastic pipe 2, and each connecting pin system is there are one 21, internal ring portions 23 of outer portion and is formed in
A cyclic annular socket joint chamber 22 between outer portion 21 and internal ring portion 23, steel-plastic composite pressure pipe material 1 is inserted in cyclic annular socket joint chamber 22
In, identification ring 3 is equipped between outer plastic pipe layer 11 and outer portion 21, and form in the flange 31 and outer portion of 3 end of identification ring
21 end face 211 is inconsistent, improvement be in steel-plastic composite pressure pipe material 1 and when 2 welding of plastic pipe, identification ring 3 it is convex
Edge 31 and the end face 211 of outer portion 21 produce gap Q.
The wall of its port 210 of outer portion 21 be in circular conical surface, identification ring 3 be assign in the port of outer portion 21 210, and
The inner wall of identification ring 3 is adapted with the surface of outer plastic pipe layer 11, conical surface and its port 210 of outer portion 21 of identification ring 3
Wall be adapted.
When specific assembling, connection, first identification ring 3 is set on steel-plastic composite pressure pipe material 1, then steel plastic compount pressure
Tubing 1 is planted in the cyclic annular socket joint chamber 22 of plastic pipe 2, and then slides and install identification ring 3, by means of external force by identification ring
3 assign in the port of outer portion 21 210, the conical surface of the inner wall, identification ring 3 that make identification ring 3 respectively with outer plastic pipe layer
11 surface, the wall of its port 210 of outer portion 21 are in close contact, and make the end face of the flange 31 and outer portion 2 of identification ring 3
211 is inconsistent.
After the completion of above-mentioned preparation, so that it may to carry out electromagnetic welding operation, in the inserting section of steel-plastic composite pressure pipe material 1
It is set with electromagnetic induction heater W on corresponding plastic pipe 2 and may make intermediate steel pipe layer 12 after magnetic induction heaters W is powered
It is located at the inserting section self-heating in cyclic annular socket joint chamber 22, and generated continuous high temperature is enough the corresponding plastics of plug-in position
It is melted, melting process is accompanied by heat towards transmitting except plug-in position, this forces identification ring 3 relative to plastic pipe 2
The end face 211 for generating a little mobile identification ring 3 Yu plastic pipe 2 its outer portion 21 after cooling and solidifying is provided with gap Q,
Steel-plastic composite pressure pipe material 1, plastic pipe 2 and 3 welding of identification ring link into an integrated entity.
According to the presence or absence of gap Q, whether recognizable steel-plastic composite pressure pipe material 1 had carried out welding with plastic pipe 2
Operation.
Identification ring 3 uses plastic material, it is plastic identification ring.
