Oppfinnelsen angår en anordning for The invention relates to a device for
skjøtning av rør eller slanger av plast eller splicing of plastic pipes or hoses or
lignende materiale, idet anordningen om-fatter en hylse fremstillet fortrinnsvis av similar material, the device comprising a sleeve made preferably of

oppvarmningsmidler har det tidligere vært heating means there have been in the past
foreslått å anvende en varmetråd innleiret proposed to use a heating wire embedded
i hylsens vegg. in the wall of the sleeve.
Slike kjente sveiseforbindelser har Such known welding connections have
stillet strengere krav til rørenes ytterdia-meter- toleranser enn det har vært mulig set stricter requirements for the pipes' outer diameter tolerances than has been possible
å få som vanlig handelsvare. En annen to obtain as usual merchandise. Another
uheldig omstendighet ved å legge varmetråden i ytre hylse er at straks oppvarm-ningen startes vil det ytre rør først bli An unfortunate circumstance of placing the heating wire in the outer sleeve is that as soon as the heating is started, the outer tube will first become
varmt og utvide seg, hvorved dets kontakt warm and expand, whereby its contact

Dette er særlig tilfelle hvor det allerede på This is particularly the case where it already on
forhånd er en liten klaring mellom hylse advance is a small clearance between sleeve
og rør. and stir.
Ved slike kjente skjøtehylster har den In the case of such known extension sleeves, it has
ulempe gjort seg gjeldende at man får en The disadvantage is that you get one
sammensveisning mellom respektive rør-ende og skjøtehylsens indre vegg slik at welding between the respective pipe end and the joint sleeve's inner wall so that
trykkvæskefuktighet fra rørledningens indre vil trenge ut mellom rørendene og pressurized liquid moisture from the inside of the pipeline will penetrate between the pipe ends and

ekspansjon og kontraksjon ved annen virk-ning vil skjøten lett kunne svekkes og til-slut ødelegges hva tetning angår. expansion and contraction due to other effects, the joint could easily be weakened and eventually destroyed as far as the seal is concerned.
Oppfinnelsen tar sikte på å tilveie-bringe en skjøtehylse av den ovennevnte type, men utformet slik at der fåes en effektiv sammensveisning av selve rør-endene med hverandre samtidig som det parti av skjøtehylsen som omgir selve sam-menstøtsflaten for rørendene deltar i sammensveisningen. Derved blir det ingen mulighet for fuktighet eller annet fluidum til å kunne trenge seg ut i selve skjøteste-det og bevirke at tetningen trues. The invention aims to provide a joint sleeve of the above-mentioned type, but designed in such a way that the pipe ends themselves are effectively welded to each other at the same time that the part of the joint sleeve which surrounds the actual contact surface for the pipe ends participates in the welding. There is thus no possibility for moisture or other fluid to be able to penetrate into the joint itself and cause the seal to be threatened.
Ifølge oppfinnelsen oppnåes denne ovennevnte hensikt ved at der anordnes en hylse fortrinnsvis av samme materiale som de rør eller slanger som skal skjøtes. Hylsen er sirkulært sylindrisk og med passende lengde for å gi så lang overlapping over de to rørender som skal skjøtes at man får god støtte for disse. Fortrinnsvis på midten av denne hylse anordnes det så en skrueviklet varmetråd som forløper periferielt langs hylsens innervegg, idet var-metrådens to ender er ført ut gjennom rør-veggen for å kunne tilkobles en passende strømkrets f. eks. et akkumulatorbatteri. According to the invention, the above purpose is achieved by arranging a sleeve preferably of the same material as the pipes or hoses to be joined. The sleeve is circularly cylindrical and of the appropriate length to provide such a long overlap over the two pipe ends to be joined that you get good support for them. Preferably in the middle of this sleeve, a screw-wound heating wire is then arranged which runs circumferentially along the inner wall of the sleeve, the two ends of the heating wire being led out through the pipe wall in order to be able to connect a suitable circuit, e.g. an accumulator battery.
Når rørendene føres inn i hylsen vil de begge på midten støte mot den skruevik-lede varmetråd og når den tilkobles strøm-kilden vil oppvarmning av tråden bevirke sammensmeltning av rørendene, samtidig som det omgående parti av hylsen deltar i sammensveisningen. Etter at skjøt opp-nådd på denne måte er blitt utført vil så varmetråden bli liggende innstøpt i skjøte-fugen mellom rørendene hvor den ytterligere bidrar til å forsterke skjøten. When the tube ends are fed into the sleeve, they will both collide in the middle with the screw-wound heating wire and when it is connected to the power source, heating of the wire will cause the tube ends to fuse together, while the immediate part of the sleeve participates in the welding. After the joint achieved in this way has been carried out, the heating wire will then be embedded in the joint joint between the pipe ends where it further contributes to strengthening the joint.
Til bedre forståelse av oppfinnelsen skal denne beskrives nærmere under hen-visning til et par utførelseseksempler vist på vedføyede tegning. For a better understanding of the invention, it will be described in more detail with reference to a couple of design examples shown in the attached drawings.
Fig. 1 viser perspektivisk en skjøte-hylse ifølge oppfinnelsen. Fig. 2 viser i aksialsnitt hylsen ifølge fig. 1 anbragt omkring to rørender som skal sammensveises. Fig. 3 viser et bruddstykke av anordningen ifølge fig. 2 etter utført sammensmeltning. Fig. 4 viser en modifisert detalj ved anordningen ifølge oppfinnelsen. Fig. 1 shows a perspective view of a joint sleeve according to the invention. Fig. 2 shows in axial section the sleeve according to fig. 1 placed around two pipe ends to be welded together. Fig. 3 shows a broken piece of the device according to fig. 2 after completed fusion. Fig. 4 shows a modified detail of the device according to the invention.
Hylsen 1 er fremstillet sirkulært sylindrisk av et passende smeltbart og isoler-ende materiale fortrinnsvis av samme materiale som de rør eller slanger hvis ender skal skjøtes inne i hylsen. Gjennom hylsens vegg er der omtrent på midten ført tilkob-lingsstråder 2,2' for en rundtgående peri-ferien varmespiral 3 lagt i skruevikling rundt hylsens innervegg. Tråden 3 kan ligge inne i hylsen bare fastholdt ved hjelp av gjennomføringene 2,2' og eventuelt et visst spenn som holder den ut mot rørets innervegg eller den lokaliseres mere bestemt ved at det sendes en kortvarig strøm-puls gjennom den etterat den er anbragt på plass i hylsen. Derved vil de ytre partier av viklingens vindinger smeltes fast til innsiden av hylsen. Eventuelt kan der i hylsens innside være tatt ut en rille for å gi lokalisering for varmetråden slik som antydet i fig. 4 hvor der i hylsen 1' er tatt ut et rundtgående spor 6. Om ønskes kan begge metoder for lokalisering kombineres. The sleeve 1 is made circularly cylindrical from a suitable fusible and insulating material, preferably from the same material as the pipes or hoses whose ends are to be joined inside the sleeve. Connecting wires 2,2' for a circumferential peripheral heating coil 3 laid in screw winding around the inner wall of the sleeve are routed through the wall of the sleeve approximately in the middle. The wire 3 can lie inside the sleeve only held in place by means of the grommets 2,2' and possibly a certain tension which holds it out against the inner wall of the pipe or it can be located more precisely by sending a short current pulse through it after it has been placed on space in the sleeve. Thereby, the outer parts of the turns of the winding will be fused to the inside of the sleeve. Optionally, a groove can be taken out inside the sleeve to provide localization for the heating wire as indicated in fig. 4 where in the sleeve 1' a circumferential groove 6 has been taken out. If desired, both methods of localization can be combined.
Når hylsen ifølge fig. 1 skal anvendes for skjøting av to rørender 4 og 5 innføres disse i motsatt retning slik som vist med pilene i fig. 2, idet de begge støter mot båndtråden 3 i midten av hylsen 1. Strøm tilkobles så ledningene 2,2' i et på forhånd bestemt passende tidsrom, hvorved endepartiene 4', 5' for rørene 4 og 5 blir til-strekkelig oppvarmet for at varmetråden 3 trenger inn i endepartiene samtidig som disse sammensmeltes til hverandre. Varmetråden vil også varme opp en del av hylsen 1 slik at det parti som ligger omkring sammensveisningssømmen mellom rørendene også deltar i sammensmeltingen slik som antydet i fig. 3. Ved denne anordning fåes således en meget effektiv sammensveisning av rørendene og av disse til skjøtehylsen, hvorved oppnåes en used-vanlig sterk og pålitelig skjøt som ikke gir noen mulighet for utetthet. Etter sammen-sveisningens utførelse vil vindingene i vik-lingen 3 slik som det tydelig sees av fig. 3 bli liggende inne i godset i skjøtefugen og bidrar her ytterligere til å forsterke denne. When the sleeve according to fig. 1 is to be used for joining two pipe ends 4 and 5, these are introduced in the opposite direction as shown by the arrows in fig. 2, as they both collide with the ribbon wire 3 in the middle of the sleeve 1. Current is then connected to the wires 2,2' for a predetermined suitable period of time, whereby the end parts 4', 5' of the pipes 4 and 5 are sufficiently heated so that the heating wire 3 penetrates into the end parts at the same time as these fuse together. The heating wire will also heat up a part of the sleeve 1 so that the part which lies around the welding seam between the tube ends also participates in the fusion as indicated in fig. 3. With this device, a very efficient welding of the pipe ends and of these to the joint sleeve is thus achieved, whereby an exceptionally strong and reliable joint is obtained which gives no possibility of leakage. After the welding has been performed, the windings in the winding 3, as can clearly be seen from fig. 3 remain inside the goods in the joint and contribute here further to strengthening it.
Vanligvis vil en slik skruevikling være den mest hensiktsmessige for varmetråden. Det er midlertid intet til hinder for at denne kan vikles om ovalt eller i sik-sak for-løpende vindinger. Den sirkulære viklings form er imidlertid den enkleste og vil der-for vanligvis i praksis være den som kom-mer til anvendelse. Usually, such a screw winding will be the most appropriate for the heating wire. In the meantime, there is nothing to prevent this from being wound in oval or zig-zag continuous windings. However, the circular winding form is the simplest and will therefore usually be the one used in practice.
Det er selvsagt ikke noe til hinder for at hylsen 1 kan være av annet materiale enn de rør- eller slangeender som skal skjøtes. Hovedsaken er at hylsen er av iso-lerende materiale. Helst bør den imidlertid være av materiale som deltar i sammensveisningen slik som ovenfor beskrevet selv om dette ikke er noen betingelse. There is of course nothing to prevent the sleeve 1 from being made of a different material than the pipe or hose ends to be joined. The main thing is that the sleeve is made of insulating material. Preferably, however, it should be of material that participates in the welding as described above, although this is not a condition.
