Abstract

A smooth end ring 6 is arranged in a folded metal pipe 5 which serves for interconnecting smooth pipes 1, 2 to form a ventilation duct. This ring extends a little way into the folded pipe 5 and is mounted so as to press against the inside of the folded pipe 5. The end ring 6 engages, with a portion 7, around the edge portion 8 of the folded pipe 5. When an extension pipe 3 provided with a sealing ring 4 is inserted into the folded pipe 5, the sealing ring 4 is intended to bear sealingly against the smooth inside of the end ring 6. <IMAGE>

Description

4.66 616 bruten sidovy anordningen enligt uppfinningen och en del av ett veckat rör åtskilda, fig. 2 anordningen och det veckade röret sammansatta och fig. 3 i perspektiv en tillämpning med det veckade röret tjänande som rörkrök. 4.66 616 broken side view device according to the invention and part of a pleated tubes separated, Fig. 2 the device and the pleated tube assembled and Fig. 3 is a perspective view of an application with the pleated tube serving as pipe bend.

Vid sammankoppling av två släta metallrör 1, 2 för bildande av en ventilationskanal användes enligt känd teknik ett slätt skarvrör 3. Detta skarvrör 3 överbryggar således skarven mellan de båda metall- rören 1, 2 och medelst en i varje metallrör införd tätningsring 4 på skarvröret 3, anpressande mot insidan av metallröret 1 resp. 2, bildas en lufttät skarv.When connecting two smooth metal pipes 1, 2 for formation of a ventilation duct, according to the prior art, a smooth splice pipe was used 3. This splice tube 3 thus bridges the splice between the two metal pipes 1, 2 and by means of a sealing ring 4 inserted in each metal pipe on the joint pipe 3, pressing against the inside of the metal pipe 1 resp. 2, is formed an airtight joint.

När ett par metallrör 1, 2 bildar vinkel med varandra, använ- des för sammankoppling av rören ett veckat metallrör 5, som således bildar en rörkrök. Om ett skarvrör 3 förbindes på samma sätt med det veckade röret 5 som med ett slätt rör 1 eller 2 uppstår emellertid, såsom nämnts ovan, problem med tätningen beroende på det veckade rörets 5 rillor. Skarvröret 3 får därför fästas mot insidan av det veckade röret 5 genom pressning, och tätning sker sedan mot skarv- rörets 3 släta utsida. Denna procedur är omständlig och kräver olika verktyg för genomförande av en skarvning.When a pair of metal tubes 1, 2 form an angle with each other, For interconnecting the pipes, a pleated metal pipe 5 was formed, which thus forms a pipe bend. If a splice pipe 3 is connected in the same way to it pleated tube 5 which arises with a smooth tube 1 or 2, however, as mentioned above, problems with the seal due to the pleated the tube 5 grooves. The splice tube 3 may therefore be attached to the inside of it pleated pipe 5 by pressing, and sealing then takes place against the joint the smooth outside of the tube 3. This procedure is cumbersome and requires different tools for performing a splice.

Genom anordningen enligt uppfinningen underlättas ovan be- skrivna skarvningsarbete väsentligt. Det veckade röret 5 är enligt uppfinningen försett med en slät ändring 6, som sträcker sig ett stycke in i det veckade röret 5 anpressande mot dettas insida. Med ett parti 7 griper ändringen 6 om det veckade rörets 5 kantparti 8.The device according to the invention facilitates the above written splicing work significantly. The pleated tube 5 is according to the invention provided with a smooth change 6, which extends one piece into the pleated tube 5 pressing against its inside. With a portion 7 grips the change 6 about the edge portion 8 of the pleated tube 5.

Sammanmontering av ett med en tätningsring 4 försett skarvrör 3 med ett veckat metallrör 5 enligt uppfinningen sker nu lika enkelt som vid sammanförande av skarvröret 3 med ett slätt rör 1 eller 2.Assembly of a splice pipe fitted with a sealing ring 4 3 with a pleated metal pipe 5 according to the invention now takes place just as easily as when joining the splice tube 3 with a smooth tube 1 or 2.

Skarvröret 3 föres in i det veckade rörets 5 ändring 6, så att tät- ningsringen 4 kommer att anligga med tryck mot ändringens 6 släta insida. Någon ytterligare åtgärd behöver icke utföras.The splice tube 3 is inserted into the change 6 of the pleated tube 5, so that the ring 4 will abut with pressure against the smoothness of the change 6 inside. No further action needs to be taken.

Vid fastgöring av en ändring 6 vid ett veckat metallrör 5, föres ändringen 6 ned i det veckade röret 5 omgripande dettas kant- parti 8, dvs från läget i fig. 1 till läget i fig. 2, varefter ändringen 6 med hjälp av ett verktyg expanderas radiellt utåt till 466 616 anpressning mot det veckade rörets 5 insida. Samtidigt formas en utåt- riktad vuist 9 i ändringen 6 innanför dennas omgripande parti 7. Denna vuist 9 tiilförsäkrar en god fasthåiining av ändringen 6 vid det veckade metaiiröret 5.When attaching a change 6 to a pleated metal tube 5, the change 6 is brought down into the pleated tube 5 surrounding its edge portion 8, i.e. from the position in Fig. 1 to the position in Fig. 2, after which the change 6 by means of a tool is expanded radially outwards to 466 616 pressing against the inside of the pleated tube 5. At the same time, an outward directed vuist 9 in amendment 6 within its ambient portion 7. This vuist 9 assures a good adherence to the amendment 6 to it pleated metal tube 5.

Uppfinningen är icke begränsad tiil det visade och beskrivna utförandet utan kan varieras på fiera sätt inom ramen för efter- föijande krav. Ändringen 6 kan såiedes vara formad på annat än visat sätt så iänge den uppfyHer viikoret att bilda en siät insida i det veckade röret 5 för att skapa en god anïiggning för tätningsringen 4.The invention is not limited to what is shown and described execution but can be varied in several ways within the following requirements. The change 6 can thus be shaped in other ways than shown so it does not fulfill the purpose of forming a sieve inside it pleated pipe 5 to create a good fit for the sealing ring 4.
