Electric-fusion generally is used for connecting tube, hereinafter simply describes this electric-fusion of pipeline.
In the bonding process of the pipeline of making by polyethylene or polypropylene that will be used as water supply pipe and other purpose, used heat fusion methods to obtain to seal completely basically.
Traditional heat fusion methods comprises butt fusion welding, thermofusible spigot welding, electric smelting socket weld or the like.
Butt fusion welding is also referred to as butt welding, does not wherein need to use extra bellmouth that the end face of pipeline is interconnected.Specifically, butt fusion welding is to finish according to following step: use hydraulic pressure or the pneumatic fixture mode fixing tube with the mutual opposite of end face that is used to weld of pipeline; The end face that the is used in welding cunning that flattens; Between described end face, place heating plate; The end face that will be used to weld by hydraulic pressure or air pressure presses heating plate tightly; Heating plate is heated to suitable fusing point (approximately being 210 ℃ for polyethylene for example) with the end face fusing with pipeline; After fusing, heating plate is removed fast; The end face of the fusing of pipeline is pressed tightly mutually; And the cooling of when pipeline is remained on depressed position, pipeline being carried out one period scheduled time, so that the melt portions of pipeline is solidified, thus pipeline is bonded together.
This method links together pipeline by the fusing pipeline material, does not use extra bellmouth.But this method needs Hot welding, and described Hot welding is heavier so be difficult to move on the working position, and this in addition Hot welding also has complicated structure.
Another kind method is to use common bellmouth, and the interior week of wherein said bellmouth and the periphery of pipeline melt then simultaneously and bond together.That is to say, the interior periderm of the periphery of pipeline and bellmouth heats simultaneously, thereby the face of weld of any is all heated simultaneously in the interior week of the periphery of pipeline and bellmouth, when they are heated to enough heat, thereby will contact tightly with the periphery of pipeline on the periphery that be quickly installed to pipeline interior week of bellmouth.Then, the structure that obtains is cooled off one section preset time under this tightly state of contact.
Another method is electric socket joint welding.This method is used the bellmouth with heating element, for example inserts the heating coil in the bellmouth.The bellmouth injection mould is shaped on the heating element that is arranged on integratedly wherein.Heating coil can comprise the electric wire that for example copper cash, COPPER ALLOY WIRE, nichrome wire etc. have special resistance rank.Described bellmouth for example can be made in the following manner: reeling is coated with the resistive conductor of thermoplastic resin; Electric terminal is connected on the end of electric wire; Electric wire is inserted in the mould; And be molded as resin and electric wire as a whole.After bellmouth is made by this way, bellmouth is installed to the pipeline that is used for welding, apply the electric current of one period scheduled time by single power supply to described bellmouth, so that the melting simultaneously in interior week and bond together of the periphery of pipeline and bellmouth.
