Description
Technical field
The present invention relates to plastic pipe field more particularly to a kind of electric smelting elbow member and thereafter cloth silk technique.
Background technique
PE electric melting pipe fittings are divided into exposed silk electric melting pipe fittings, plastic silk electric melting pipe fittings and rear cloth silk electric melting pipe fittings, three kinds of techniques
It has their own advantages, the electric smelting interface of exposed silk electric melting pipe fittings welding under identical condition, peel strength and welding operation fault tolerance
Electric melting pipe fittings of the rate all than in addition several technique productions are relatively slightly better, and plastic silk electric melting pipe fittings are in steel wire mesh frame PE
Connection on pipeline has the advantages that uniqueness again, and as rear cloth silk heating wire electric melting pipe fittings, it is injection molding pipe through turnery processing
After embed the wire, therefore first two production technology is unable to reach when in dimensional accuracy, wherein application No. is
It discloses and is used in the Chinese patent for the cutter being routed after the entitled a kind of pair of tube body progress bareing of CN201610224262.5
The operating process to cloth silk after electric melting pipe fittings is carried out to the cutter that cloth silk after electric melting pipe fittings is processed, and with the cutter.
For rear cloth silk electric melting pipe fittings, need that conductive connector is arranged in the end of pipe fitting, so that with the electric heating in pipe fitting
Silk conducting, and then realize that electrothermal wire heating is then to pipe fitting electric fusion welding when being powered.When being processed for the rear cloth silk of elbow member,
Prior art is first to carry out cloth silk to one end of elbow member then to reserve one section of heating wire towards pipe fitting inner end, then another to pipe fitting
One end carries out cloth silk and also reserves one section of heating wire towards pipe fitting inner end, finally twists joint both ends heating wire and realizes bend pipe together
The conducting of part both ends heating wire.
However aforesaid way is used, elbow member is being powered so that when electrothermal wire heating's electric fusion welding, is easy so that twisting joint
Heating wire fusing together usually occurs in use process cannot achieve asking for welding between pipe fitting since heating wire fuses
Topic.
