Description
Oppfinnelsen vedrører en anordning ved bølgeformede metall-rør, hvilke tjener til å sammenbinde glatte rør til en ventilasjonskanal. The invention relates to a device for corrugated metal pipes, which serve to connect smooth pipes to a ventilation duct.
Slike bølgede metallrør anvendes f.eks. til å danne en rørbøy. Mellom bølgerøret og det glatte rør er det derved innsatt et skjøterør med i det minste en tetningsring som ligger an mot innsiden av bølgerøret resp. det glatte rør. Skjøterørets tetningsring i anlegg mot det glatte rørets innside danner en tett skjøt uten problem. Derimot er det vanskelig å tilveiebringe samme gode tetning ved hjelp av anlegg av skjøterørets tetningsring mot innsiden av bølge-røret på grunn av dette rørs riller. Such corrugated metal pipes are used e.g. to form a pipe bend. Between the corrugated pipe and the smooth pipe, an extension pipe is thereby inserted with at least one sealing ring that rests against the inside of the corrugated pipe or the smooth tube. The joint pipe's sealing ring in contact with the inside of the smooth pipe forms a tight joint without problems. On the other hand, it is difficult to provide the same good seal by placing the joint pipe's sealing ring against the inside of the corrugated pipe due to this pipe's grooves.
Formålet med oppfinnelsen er å eliminere dette problem. Det som karakteriserer oppfinnelsen fremgår av de etterfølgende krav. The purpose of the invention is to eliminate this problem. What characterizes the invention appears from the following claims.
Oppfinnelsen skal beskrives nærmere i det etterfølgende med henvisning til de vedlagte tegninger, hvor The invention shall be described in more detail below with reference to the attached drawings, where
fig. 1 viser anordningen ifølge oppfinnelsen i brutt sideriss og en del av et bølgerør, atskilte, fig. 1 shows the device according to the invention in a broken side view and part of a wave pipe, separated,
fig. 2 anordningen og det bølgede rør sammensatt, og fig. 2 the device and the corrugated pipe assembled, and
fig. 3 i perspektiv en anvendelse med bølgerøret tjenende som en rørbøy. fig. 3 in perspective an application with the wave pipe serving as a pipe bend.
Ved sammenkopling av to glatte metallrør 1,2 for dannelse av en ventilasjonskanal anvendes ifølge kjent teknikk et glatt skjøterør 3. Dette skjøterør overlapper således skjøten mellom de to metallrør 1,2 og ved hjelp av en i hvert metallrør innført tetningsring 4 på skjøterøret 3, som presser mot innsiden av metallrøret 1 resp. 2, dannes en lufttett skjøt. When connecting two smooth metal pipes 1,2 to form a ventilation duct, a smooth joint pipe 3 is used according to known technology. This joint pipe thus overlaps the joint between the two metal pipes 1,2 and with the help of a sealing ring 4 inserted in each metal pipe on the joint pipe 3, which presses against the inside of the metal tube 1 or 2, an airtight joint is formed.
Når et par metallrør 1,2 danner vinkel med hverandre, anvendes for sammenkopl ing av rørene et bølget metallrør 5 som således danner en rørbøy. Evis et skjøterør 3 forbindes på samme måte med det bølgede rør 5 som med et glatt rør 1 eller 2, oppstår imidlertid som ovenfor nevnt, problemer med tetningen på grunn av det bølgede rørs 5 riller. Skjøterøret 3 blir derfor festet mot innsiden av bølgerøret 5 ved pressing, og tetning skjer deretter mot skjøterørets 3 glatte utside. Denne prosedyre er omstendelig og krever forskjellig verktøy for gjennomføring av en skjøting. When a pair of metal pipes 1,2 form an angle with each other, a corrugated metal pipe 5 is used to connect the pipes, which thus forms a pipe bend. If an extension pipe 3 is connected to the corrugated pipe 5 in the same way as with a smooth pipe 1 or 2, however, as mentioned above, problems with the seal occur due to the corrugated pipe 5's grooves. The joint pipe 3 is therefore attached to the inside of the corrugated pipe 5 by pressing, and sealing then takes place against the smooth outside of the joint pipe 3. This procedure is cumbersome and requires different tools to carry out a joint.
Ved hjelp av anordningen ifølge oppfinnelsen lettes det ovenfor beskrevne skjøtearbeidet vesentlig. Bølgerøret 5 er ifølge oppfinnelsen forsynt med en glatt endering 6 som strekker seg et stykke inn i bølgerøret 5 i pressanlegg mot dettes innside. Med et parti 7 griper enderingen 6 om bølgerørets 5 kantparti 8. With the aid of the device according to the invention, the splicing work described above is greatly facilitated. According to the invention, the wave tube 5 is provided with a smooth end ring 6 which extends a distance into the wave tube 5 in a press system towards its inside. With a part 7, the end ring 6 grips the edge part 8 of the corrugated tube 5.
Sammenmontering av et med en tetningsring 4 forsynt skjøterør 3 med et bølget metallrør 5 ifølge oppfinnelsen skjer nå like enkelt som ved sammenføring av skjøterøret 3 med et glatt rør 1 eller 2. Skjøterøret 3 føres inn i bølgerørets 5 endering 6, slik at tetningsringen 4 kommer til anlegg med trykk mot enderingens 6 glatte innside. Noen ytterligere foranstaltning behøver ikke utføres. Assembling an extension pipe 3 provided with a sealing ring 4 with a corrugated metal pipe 5 according to the invention is now as simple as joining the extension pipe 3 with a smooth pipe 1 or 2. The extension pipe 3 is inserted into the end ring 6 of the corrugated pipe 5, so that the sealing ring 4 comes for installation with pressure against the smooth inside of the end ring 6. No further action needs to be taken.
Ved fastgjøring av en endering 6 til et bølget metallrør 5, føres enderingen 6 ned i bølgerøret 5 idet den griper om dettes kantparti 8, dvs. fra stillingen i fig. 1 til stillingen i fig. 2, hvoretter enderingen 6 ved hjelp av et verktøy ekspanderes radielt utad til trykkanlegg mot bølgerørets 5 innside. Samtidig formes en utadrettet vulst 9 i enderingen 6 innenfor dennes omgripende parti 7. Denne vulst 9 sikrer en god fastholding av enderingen 6 i det bølgede metallrør 5. When attaching an end ring 6 to a corrugated metal pipe 5, the end ring 6 is guided down into the corrugated pipe 5 as it grips its edge part 8, i.e. from the position in fig. 1 to the position in fig. 2, after which the end ring 6 is expanded radially outward with the help of a tool to pressurize against the inside of the corrugated pipe 5. At the same time, an outwardly directed bead 9 is formed in the end ring 6 within its surrounding part 7. This bead 9 ensures a good retention of the end ring 6 in the corrugated metal tube 5.
Oppfinnelsen er ikke begrenset til den viste og beskrevne utførelse, idet den kan varieres på flere måter innen rammen for de etterfølgende krav. Enderingen 6 kan således være formet på annen måte enn den viste, så lenge den oppfyller vilkåret for å danne en glatt innside i bølgerøret 5 for å tilveiebringe et godt anlegg for tetningsringen 4. The invention is not limited to the embodiment shown and described, as it can be varied in several ways within the scope of the following claims. The end ring 6 can thus be shaped in a different way than that shown, as long as it fulfills the condition of forming a smooth inside of the corrugated tube 5 to provide a good fit for the sealing ring 4.
