Specific embodiment
Fig. 1 is the schematic cross sectional views according to the electric melting pipe fittings of the self spacing-type of line-imbedding type of the application one embodiment.
Embodiment shown in Fig. 1 is electric melting reducing tee, and the electric smelting port insertion tubing 1 in left side is illustrated in Fig. 1.As shown in Figure 1,
A kind of electric melting pipe fittings 100 of the self spacing-type of line-imbedding type are illustrated by taking electric melting reducing tee as an example.Certainly, ordinary skill
Personnel both know about, and the electric melting pipe fittings 100 of the self spacing-type of line-imbedding type are not limited to electric melting reducing tee, can also be that electric smelting is straight
The electric melting pipe fittings such as logical, electric smelting variable diameter, electric smelting equal tee, electric smelting elbow.Electric melting pipe fittings 100 generally may include: PE main body 10,
Heating wire 20 and binding post (not drawn in figure).10 inner hollow of PE main body and be interconnected, in the PE main body 10 at least
There are two electric smelting ports 11 for tool, connect corresponding tubing 1 for accommodating simultaneously electric smelting.Its described two electricity of insertion of heating wire 20
It at the inner wall of the molten corresponding PE main body 10 in port 11, is configured in the state of conduction, by the electric melting pipe fittings 100 and the pipe
1 electric fusion welding of material is together.Binding post correspondence is mounted at described two electric smelting ports, respectively with the both ends of the heating wire 20
It is connected, for connecting external welding machine.Wherein, the center position in each electric smelting port 11 close to the electric melting pipe fittings 100 is set
There is the limit divided edge structure 12 for protruding from 11 inner wall of electric smelting port, the position being inserted into for limiting the tubing 1.This implementation
In example, the electric melting pipe fittings 100 have welding cooling zone B and welding area C.The wall of the welding cooling zone of the electric melting pipe fittings 100
Thick E is greater than the wall thickness of the welding area of the electric melting pipe fittings 100.
When it is implemented, the PE main body 10 passes through injection molding.The limit divided edge structure 12 of the electric melting pipe fittings 100 is
One time turnery processing forms.The heating wire 20 is that the mode of sunkening cord is embedded in the PE main body 10 after.
The electric melting pipe fittings 100 of the self spacing-type of the line-imbedding type of the application pass through electric smelting close in each electric smelting port 11
The center position of pipe fitting 100 is equipped with the limit divided edge structure 12 for protruding from 11 inner wall of electric smelting port, the position that limitation tubing 1 is inserted into
It sets.This limit divided edge structure 12 not only has limit function, and makes wall of the wall thickness E greater than welding area for welding cooling zone
Thickness, to enhance the use intensity of electric melting pipe fittings 100.
During realizing the application, inventors have found that mounting groove in the prior art easily leads to electric melting pipe fittings simultaneously
Internal heating wire is exposed, causes welding to fail to be assembled tubing cutting.Since the electric melting pipe fittings of the prior art make not only
Machining sequence including mounting groove, the cabling processes of heating wire further include retaining ring assembling procedure, so that manufacturing procedure is complicated, at
This height.
And in the application, since PE main body 10 increases limit divided edge structure 12, so that the weldering of the electric melting pipe fittings 100
Connect sunken cord depth of the depth F greater than the welding area of the electric melting pipe fittings 100 of sunkening cord of cooling zone.So that limit divided edge structure 12 can
The depth for increasing resistance wire insertion PE main body 10, thus the phenomenon for effectively avoiding heating wire exposed.In addition, the application electric melting pipe fittings
Limit stop ring in the prior art and mounting groove is substituted in 100 itself limit divided edge structures 12, not only reduces Material Cost,
And greatly reduce the manufacturing procedure of 100 product of electric melting pipe fittings., to reduce the cost of electric melting pipe fittings 100.
In the present embodiment, the limit hill start structure curl angle is between 4 °~10 °.
Fig. 2 is the schematic partial enlarged view of A in electric melting pipe fittings shown in Fig. 1.In the present embodiment, the limit groove knot
The limit bore of structure 12 is slightly less than the outer diameter of corresponding tubing 1.The limit bore D limit of the limit divided edge structure 12 meets limit meter
Formula is calculated, calculation formula: D limit=d pipe -2es is limited, wherein D is limited to the limit bore of the limit divided edge structure 12, and d pipe is institute
The minimum average B configuration outer diameter of tubing 1 is stated, es is the scrape depth of the tubing 1.More specifically, the limit of the limit divided edge structure 12
Position bore is slightly less than 1 outer diameter lower limit value of tubing.Further, the limit divided edge structure 12 is away from 100 end face of electric melting pipe fittings
Distance H be less than or equal to standard requirements tubing 1 insertion depth.
In the present embodiment, D limits tolerable tubing 1 and slightly assigned position, and the tubing 1 uneven to notch has better fault-tolerant energy
Power.And the setting angle that can correct tubing 1 by force to the clamping action of tubing 1 avoids under gravity in tubing 1 and pipe fitting
The non-uniform phenomenon in wall gap allows limit divided edge structure 12 to clamp correction installation 1 angle of tubing, makes electric melting pipe fittings 100
And the gap J between tubing 1 is more uniform, improves 100 welding effect of electric melting pipe fittings.
