Description
151353 i151353 i
Den foreliggende opfindelse vedrører en rørsamling mellem to rørlængder, der ligger an mod hinanden ved deres endeflader, og hvis endeflader ligger i planer, der er skrå i forhold til rørlængdernes respektive længdeakser, og i disse planer har cirkulære inderflader.The present invention relates to a pipe joint between two pipe lengths which abut each other at their end faces and whose end faces lie in planes which are inclined with respect to the respective longitudinal axes of the pipe lengths and in these planes have circular inner faces.
5 Opfindelsen finder især, men ikke udelukkende, anvendelse ved forbindelse af plastrør, der anvendes i under jorden anbragte rørledninger, fx wc- og spildevandsafløb.In particular, the invention finds application, but not exclusively, for the connection of plastic pipes used in underground pipelines, e.g., toilet and sewage drains.
Fra britisk patentskrift nr. 392.734 kendes en rørsamling af den indledningsvis nævnte art. De rørlængder, som danner denne kendte 10 forbindelse, er ved de endeflader, ved hvilke rørlængderne ligger an mod hinanden, udformet med elliptisk tværsnit vinkelret på rørlængdernes respektive længdeakser. Rørlængdernes endeflader modsat de endeflader, ved hvilke rørlængderne ligger an mod hinanden, ligger i planer, der står vinkelret på rørlængdernes respektive længdeakser 15 og danner endeflader til forbindelse med konventionelle lige rørlængder med cirkulære inder- og yderflader. Disse kendte rørsamlingsrørlængder er, som man vil forstå, af en kompliceret geometrisk udformning, da rørlængdernes yderflader danner en overgang fra en cirkulær frembringer- eller ydre tværsnitsflade til en elliptisk frem-20 bringer- eller skrå ydre snitflade. Denne komplicerede geometriske udformning medfører for det første, at visse produktionsteknikker ikke er anvendelige i forbindelse med fremstillingen af sådanne rørlængder, fx ekstrudering, hvilket gør det vanskeligt at fremstille sådanne rørlængder i fx plast, og for det andet, at rørlængderne, 25 når disse er samlet og endvidere forbundet med andre rørlængder med cirkulære indre og ydre tværsnitsflader, fremtræder med en ikke-kon-tinuerlig yderflade. Denne ikke-kontinuerlige yderflade er i sig selv ikke visuel attraktiv, og gør det endvidere vanskeligt at isolere en rørsamling etableret med disse kendte rørlængder, da der ikke kan 30 benyttes præfabrikerede isoleringsbøsninger med cirkulære inderflader, da disse rørlængders yderflade varierer fra et cirkulært tværsnit til et elliptisk tværsnit.British Patent Specification No. 392,734 discloses a pipe assembly of the kind mentioned above. The pipe lengths forming this known connection are at the end faces at which the pipe lengths abut are formed with an elliptical cross section perpendicular to the respective longitudinal axes of the pipe lengths. The end faces of the pipe lengths opposite the end faces at which the pipe lengths abut, lie in planes perpendicular to the respective longitudinal axes 15 of the pipe lengths and form end faces for connection with conventional straight pipe lengths with circular inner and outer faces. These known pipe joint pipe lengths are, as will be understood, of a complicated geometric design, as the outer surfaces of the pipe lengths form a transition from a circular generating or outer cross-sectional surface to an elliptical producing or inclined outer sectional surface. This complicated geometric design leads, firstly, to certain production techniques not applicable in the manufacture of such pipe lengths, for example extrusion, which makes it difficult to manufacture such pipe lengths, for example in plastic, and secondly, when the pipe lengths are 25 assembled and further connected to other pipe lengths having circular inner and outer cross-sectional surfaces, a non-continuous outer surface appears. This non-continuous outer surface is not visually attractive in itself, and furthermore makes it difficult to insulate a pipe joint established with these known pipe lengths, as prefabricated insulating bushes with circular inner surfaces cannot be used, since the outer surface of these pipe lengths varies from a circular cross-section to an elliptical cross section.

Formålet med den foreliggende opfindelse er at tilvejebringe rørlængder, der gør det muligt et etablere en rørsamling af den indledningsvis nævnte art med disse rørlængder, hvilke rørlængder, når de er sammenkoblet, danner en cirkulær ydre flade.The object of the present invention is to provide pipe lengths which enable a pipe joint of the type mentioned initially with these pipe lengths to be established, which pipe lengths, when interconnected, form a circular outer surface.
5 Dette formål opnås med en rørsamling, der er i overensstemmelse med opfindelsen er ejendommelig ved, at vægtykkelsen af hver af rørlængderne på det sted, der grænser op til endefladen, gradvis varierer periferisk på en sådan måde, at hver rørlængde vinkelret på længdeaksen har en cirkulær ydre tværsnitsflade.This object is achieved with a pipe assembly which is in accordance with the invention is characterized in that the wall thickness of each of the pipe lengths at the location adjacent to the end surface varies circumferentially in such a way that each pipe length perpendicular to the longitudinal axis has a circular outer cross-sectional surface.
10 Med den for opfindelsen karakteristiske udformning af rørlængderne i rørsamlingen ifølge opfindelsen elimineres de ovenfor beskrevne u-lemper i henseende til produktionsteknik og ydre form ved de fra det ovennævnte britiske patentskrift kendte rørlængde.With the design characteristic of the invention in the pipe lengths in the pipe assembly according to the invention, the disadvantages described above in terms of production technique and outer form are eliminated by the pipe length known from the above-mentioned British patent specification.
Rørsamlingen omfatter fordelagtigt mellem rørlængderne anbragte 15 kobfingsorganer, der, i det mindste, når rørlængderne første gang sammenkobles, gør det muligt at dreje den ene rørlængde om sin længdeakse i forhold til den anden rørlængde på en sådan måde, at de mod hinanden anliggende endeflader bringes til at glide hen over hinanden således, at de to rørlængders vinkelorientering ændres.Advantageously, the pipe assembly comprises 15 coupling means arranged between the pipe lengths, which, at least when the pipe lengths are first coupled, allow one pipe length to be rotated about its longitudinal axis relative to the other pipe length in such a way that the abutting end faces are brought together. to slide over each other so that the angular orientation of the two tubing lengths is changed.
20 I overensstemmelse med en første udførelsesform for rørsamlingen ifølge opfindelsen har koblingsorganerne en indstiksdel på den ene rørlængde og en komplementær modtagedel på den anden af rørlængderne. Indstiks- og modtagedelene kan være udformet i ét med de nævnte rørlængder, idet indstiksdelen omfatter en manchet, der 25 omslutter den tilhørende rørlængde, og idet modtagedelen omfatter en ud fra endefladen på den tilhørende rørlængde udragende muffeformet forlængelse.In accordance with a first embodiment of the pipe assembly according to the invention, the coupling means has a plug part on one pipe length and a complementary receiving part on the other of the pipe lengths. The insert and receive portions may be formed integrally with said pipe lengths, the insert portion comprising a sleeve enclosing the associated pipe length and the receiving portion comprising a sleeve-shaped extension projecting from the end surface of the associated pipe length.
Manchetten og den dermed samvirkende muffeformede forlængelse kan, efter at rørlængderne er bragt i den ønskede indbyrdes vinkelorien-30 tering, fikseres i forhold til hinanden fx ved svejsning ved hjælp af et opløsningsmiddel, eller manchetten og den muffeformede forlængelse og dermed de tilhørende rørlængder kan i stedet låses i forhold til 3 151353 hinanden, idet manchetten er indrettet til at blive låst i en snaplåse-pasning i den muffeformede forlængelse.The sleeve and the cooperating sleeve extension can be fixed relative to each other, for example, by welding by means of a solvent, after the pipe lengths have been brought into the desired angular orientation, or the sleeve and sleeve-shaped extension and thus the associated pipe lengths can be fixed. the site is locked relative to each other, the cuff being arranged to be locked in a snap-lock fit in the sleeve-shaped extension.
I overensstemmelse med en anden udførelsesform for rørsamlingen ifølge opfindelsen er rørlængderne på deres yderflader udformet med pe-5 rifert udragende flanger, idet koblingsorganerne er indrettet til at indgribe med disse flanger på en sådan måde, at rørlængderne holdes sammen.In accordance with another embodiment of the pipe assembly according to the invention, the pipe lengths on their outer surfaces are formed with peripherally extending flanges, the coupling means being arranged to engage with these flanges in such a way that the pipe lengths are held together.
I denne udførelsesform kan rørlængderne ligeledes forbindes hermetisk med hinanden ved direkte forbindelse, fx ved sammensvejsning ved 10 hjælp af et opløsningsmiddel, efter at rørlængderne er blevet indstillet i den ønskede indbyrdes vinkelorientering. I overensstemmelse med en videre udførelsesform for rørsamlingen ifølge opfindelsen er der mellem flangerne placeret en tætningsring, som holdes sammentrykket af koblingsorganerne og tjener til at tætne forbindelsen mellem rør-15 længderne. Koblingsorganerne kan i overensstemmelse med denne udførelsesform for rørsamlingen ifølge opfindelsen omfatte en opdelt krave med et rendeformet tværsnit, hvis sidevægge indgriber med flangernes bort fra hinanden vendende sideflader, samt organer til at holde kravens dele sammen, efter at disse er blevet anbragt på rør-20 længderne.In this embodiment, the pipe lengths can also be hermetically connected to one another by direct connection, for example by welding together by means of a solvent after the pipe lengths have been adjusted to the desired angular orientation. In accordance with a further embodiment of the pipe assembly according to the invention, there is located between the flanges a sealing ring which is held compressed by the coupling means and serves to seal the connection between the pipe lengths. The coupling means, in accordance with this embodiment of the pipe assembly according to the invention, may comprise a divided collar with a gutter-shaped cross section, the side walls of which engage the facing faces of the flanges and means for holding the parts of the collar together after they have been placed on the pipe-20. lengths.
Organerne til at holde kravens dele sammen kan yderligere omfatte et bånd, der strækker sig perifert omkring kraven, og som med en prespasning er ført ind over denne, idet båndet fordelagtigt kan have langs sine to sidekanter udformede vulster, der er beliggende på 25 hver sin side af kraven og tjener til at holde denne på plads, eller kravens dele kan ved samlingsstedet danne et radialt udragende fremspring, på hvilket organerne til at holde kravens dele sammen er anbragt med en prespasning, idet fremspringene yderligere kan have et svalehaleformet tværsnit, og idet organerne til at holde kravens 30 dele sammen kan omfatte klemmer med komplementære svalehaleformede render.The means for holding the parts of the collar together may further comprise a band extending circumferentially around the collar which is inserted with a pressing fit over it, the belt being advantageously having beads formed along its two lateral edges, which are disposed on each of its sides. side of the collar and serves to hold it in place, or the parts of the collar may form at the assembly site a radially projecting projection, on which the means for holding the collar parts together are provided with a press fit, the projections further having a dovetail-shaped cross-section, the means for holding the 30 parts of the claim together may comprise clamps with complementary dovetail-shaped grooves.
Opfindelsen vil herefter blive nærmere forklaret under henvisning til tegningen, på hvilken fig. 1-4 illustrerer princippet for opfindelsen, 4 151353 medens fig. 5-11 viser udførelsesformer for rørsamlingen ifølge opfindelsen.The invention will now be explained in more detail with reference to the drawing, in which 1-4 illustrate the principle of the invention, while FIG. 5-11 show embodiments of the pipe assembly according to the invention.
På tegningen viser fig. 1 den ene af rørlængderne set i en retning vinkelret på dens 5 skrå endeflades plan, fig. 2 et snit efter linjen A-A i fig. 1, fig. 3 den i fig. 2 viste rørlængde set i den ved pilen Z angivne retning, fig. 4 forskellige vinkelorienteringer, med hvilke de to rørlængder 10 kan forbindes med hinanden, fig. 5 et snit gennem en første udførelsesform for rørsamlingen ifølge opfindelsen med en koblingsart, der er sammensvejset ved hjælp af opløsningsmiddel, fig. 6 den ene af rørlængderne set i den med pilen Y i fig. 5 angivne 15 retning, fig. 7 et snit gennem en anden udførelsesform, fig. 8 i større målestok et snit gennem en del af den anden udførelsesform efter linjen B-B i fig. 9, fig. 9 et snit efter linjerne C-C i fig. 8, 20 fig. 10 et snit gennem en tredje udførelsesform for rørsamlingen ifølge opfindelsen efter linjen D-D i fig. 11, og fig. Π viser et snit efter linjen E-E i fig. 10.In the drawing, FIG. 1 shows one of the pipe lengths in a direction perpendicular to the plane of its 5 oblique end faces; FIG. 2 is a sectional view taken along line A-A of FIG. 1, FIG. 3 shows the one shown in FIG. 2 in the direction shown by the arrow Z, FIG. 4 different angular orientations with which the two pipe lengths 10 can be connected to each other; 5 is a section through a first embodiment of the pipe assembly according to the invention with a coupling type welded by means of solvent; FIG. 6 shows one of the lengths of pipes in the arrow Y in FIG. 5, FIG. 7 is a section through another embodiment; FIG. 8 is an enlarged sectional view of part of the second embodiment taken along line B-B in FIG. 9, FIG. 9 is a sectional view along lines C-C of FIG. 8, 20 FIG. 10 is a section through a third embodiment of the pipe assembly according to the invention along the line D-D in FIG. 11, and FIG. Π shows a section along line E-E in fig. 10th
I fig. 1-4 er der vist to rørlængder 1 og 2, der har cirkulære ydre tværsnitsflader og er af plastmateriale, og hvis endeflader er udfor-25 met således, at de ligger i planer, der er skrå i forhold til de respektive længdeakser 3 og 4 og danner samme vinkel med disse. Hvis de to rørlængder samles således, at de to endeflader ligger an mod hinanden, og rørlængden 2 drejes om sin længdeakse, vil endefladerne glide langs hinanden på en sådan måde, at rørlængden 2 bringes til 30 at indtage forskellige vinkelorienteringer i forhold til rørlængden 1.In FIG. 1-4, two pipe lengths 1 and 2 are shown which have circular outer cross-sectional surfaces and are of plastic material and whose end faces are designed to lie in planes inclined to the respective longitudinal axes 3 and 4 and forming the same angle with these. If the two pipe lengths are joined together so that the two end faces abut and the pipe length 2 is rotated about its longitudinal axis, the end faces will slide along each other in such a way that the pipe length 2 is caused to take different angular orientations with respect to the pipe length 1.
Fig. 4 viser tre sådanne vinkelorienteringer. Under én hel omdrejning vil rørlængden 2's akse 4 beskrive en kegleflade.FIG. 4 shows three such angular orientations. During one full turn, the axis 4 of the pipe length 2 will describe a cone surface.
Hvis vægtykkelsen af rørlængderne 1 og 2 er ensartet ved endefladerne, vil der som følge af de elliptiske tværsnit ved deres skrå en- 5 151353 deflader fremkomme et trin ved samlingen mellem de to rørlængder, når disse ikke er koaksiale. For at undgå dette varierer rørlængdernes vægtykkelse således, at rørlængdernes inderflader i de skrå endefladers planer er cirkulære. Af fig. 1, 2 og 3 fremgår det, 5 hvordan dette kan opnås. Hvis vægtykkelsen er ensartet, vil stor aksen for det elliptiske tværsnit være KL, og lilleaksen vil være MN.If the wall thickness of the pipe lengths 1 and 2 is uniform at the end faces, due to the elliptical cross sections at their inclined end faces, a step will occur at the joint between the two pipe lengths when these are not coaxial. To avoid this, the wall thickness of the pipe lengths varies such that the inner surfaces of the pipe lengths in the planes of the inclined end surfaces are circular. In FIG. 1, 2 and 3 show how this can be achieved. If the wall thickness is uniform, the large axis of the elliptical cross section will be KL and the small axis will be MN.
For at danne en cirkel med centrum O og radius OK er det nødvendigt at gøre væggen tyndere som vist med en punkteret linje og således, at = KL.In order to form a circle with center O and radius OK, it is necessary to make the wall thinner as shown by a dotted line and so that = KL.
10 For en rørlængde, hvis inderdiameter eksempelvis er 103 mm, og hvor endefladerne danner en vinkel o =11 1/4°, kan det beregnes, at KL = mV = 105,02 mm.10 For a pipe length, the inside diameter of which is, for example, 103 mm and the end faces forming an angle o = 11 1/4 °, it can be calculated that KL = mV = 105.02 mm.
Fig. 5 og 6 viser en første udførelsesform for rørsamlingen ifølge opfindelsen med en koblingsart, der svejses ved hjælp af et opløs- 15 ningsmiddel. For at muliggøre sammenkobling af de to rørlængder 1 og 2 er rørlængden 1 forsynet med en i ét med rørstykket udformet manchet 6, der omslutter rørlængden 1, og rørlængden 2 er forsynet med en i ét stykke dermed udformet og fra rørstykkets endeflade udragende muffeformet forlængelse 7, der optager manchetten 6. For 20 at muliggøre drejning af rørlængden 2 om sin længdeakse 4 i forhold til den anden rørlængde 1 for frembringelse af en ønsket vinkel mellem rørlængderne danner de med hinanden indgribende flader på manchetten 6 og muffen 7 en kegle, hvis akse falder sammen med aksen for den kegle, der frembringes af rørlængden 2’s længdeakse 25 4, når denne rørlængde 2 drejes.FIG. 5 and 6 show a first embodiment of the pipe assembly according to the invention with a coupling type which is welded by means of a solvent. To enable coupling of the two pipe lengths 1 and 2, the pipe length 1 is provided with a sleeve 6 integrally formed with the pipe piece 1, which encloses the pipe length 1, and the pipe length 2 is provided with a one-piece molded projection 7 extending from the end piece of the pipe piece 7. accommodating the sleeve 6. To enable rotation of the tube length 2 about its longitudinal axis 4 with respect to the second tube length 1 to produce a desired angle between the tube lengths, the engaging surfaces of the sleeve 6 and the sleeve 7 form a cone whose axis coincides with the axis of the cone produced by the longitudinal axis 4 of the tube length 2 as this tube length 2 is rotated.
Den muffeformede forlængelse 7 er ved sin yderste kant forsynet med en læbe 8, der smutter ind bag manchetten 6’s bageste kant. For at forøge læben 8's bøjelighed er den som vist i fig. 6 udformet med 1 afbrydelser 8 . 1The sleeve-shaped extension 7 is provided at its outer edge with a lip 8 which snaps in behind the rear edge of the cuff 6. In order to increase the flexibility of the lip 8, as shown in FIG. 6 designed with 1 interruptions 8. 1
De med hinanden indgribende flader på manchetten 6 og muffen 7 påføres opløsningsmiddel, så at rørlængderne, efter at de er blevet anbragt i den ønskede vinkelstilling, svejses sammen.The engaging surfaces of the sleeve 6 and the sleeve 7 are applied solvent so that the pipe lengths, after being placed in the desired angular position, are welded together.

Som vist i fig. 5 er rørlængden 2 ved den ende, der er modsat den ende, som er forbundet med rørlængden 1, udformet med en konventionel muffe til optagelse af en tap på en anden rørlængde. Den kunne i stedet være udformet som en tap, som det er tilfældet med 5 den ende af rørlængden 1, der vender bort fra rørsamlingen. De aktuelle rørlængder 1 og 2 kan udformes med forskellige længder, men de gøres fordelagtigt forholdsvis korte, så at de hensigtsmæssigt mellem to rette rørlængder kan danne et rørbøjningsstykke med variabel vinkel.As shown in FIG. 5, the pipe length 2 at the end opposite the end connected to the pipe length 1 is formed with a conventional sleeve for accommodating a pin on another pipe length. It could instead be designed as a pin, as is the case with the end of the pipe length 1 facing away from the pipe assembly. The actual pipe lengths 1 and 2 can be formed with different lengths, but they are advantageously made relatively short, so that they can conveniently form between two straight pipe lengths a variable angle pipe bending piece.
10 Fig. 7-9 viser en anden udførelsesform for rørsamlingen ifølge opfindelsen. Ved denne udførelsesform er rørlængderne 1 og 2 ved deres mod hinanden anliggende endeflader udformet med flanger 9 og 10, som, når de to rørlængder er samlet, danner en rende til anbringelse af en tætningsring 12. De to rørlængder 1 og 2 er sam- 15 menkoblet ved hjælp af en kobling omfattende en krave 13 med et rendeformet tværsnit, hvis sidevægge 14 og 15 indgriber med de bort fra hinanden vendende sideflader på flangerne 9 og 10.FIG. 7-9 show another embodiment of the pipe assembly according to the invention. In this embodiment, the pipe lengths 1 and 2 are formed at their opposite end faces by flanges 9 and 10 which, when the two pipe lengths are assembled, form a gutter for applying a sealing ring 12. The two pipe lengths 1 and 2 are joined together. interconnected by means of a coupling comprising a collar 13 having a gutter-shaped cross section, the side walls 14 and 15 engaging with the laterally facing side faces of the flanges 9 and 10.
Kraven. 13 er opslidset således, at den kan føres ind omkring rørlængderne 1 og 2, og den ene halvdel af denne krave er vist i fig.The collar. 13 is slit so that it can be inserted around the pipe lengths 1 and 2, and one half of this collar is shown in FIG.
20 7-9. Kraven 13 holdes sammen ved hjælp af et perifert plastbånd 16, der kan skubbes ind over kraven således, at dens to vulster 17 og 18 kommer til at ligge på hver sin side af kraven 13.20 7-9. The collar 13 is held together by a circumferential plastic band 16 which can be pushed in over the collar so that its two beads 17 and 18 lie on each side of the collar 13.
Båndet 16 har en sådan elasticitet, at det kan deformeres tilstrækkeligt til, at den ene af vulsterne kan føres ind over kraven. 1 2 3 4 5 6The band 16 has such elasticity that it can be deformed sufficiently that one of the beads can be inserted over the collar. 1 2 3 4 5 6
Fig. 10 og 11 viser en udførelsesform, der ligner den i fig. 7-9 vis 2 te, idet den også har flanger 9 og 10 og en tætningsring 12. Der fin 3 des også en opslidset krave 20, der har den samme funktion som 4 kraven 13. Ved denne udførelsesform er kravens to dele imidlertid 5 ved deres diametralt over for hinanden beliggende forbindelsessteder 6 forsynet med fremspring, der tilsammen danner en svalehale 22, som det fremgår af fig. 11. Plastklemmer 23 med en til svalehalen komplementær rendeform er skudt ind over svalehalerne 22 og tjener til at holde kraven 20 sammen. Klemmerne 23 holdes ved enderne på plads på kraven ved hjælp af en lille vulst 24 og en endevæg 25.FIG. 10 and 11 show an embodiment similar to that of FIG. 7-9 show 2 te, having also flanges 9 and 10 and a sealing ring 12. There is also a slotted collar 20 having the same function as the 4 collar 13. However, in this embodiment, the two parts of the collar 5 are at their diametrically opposite connecting points 6 provided with projections which together form a dovetail 22, as can be seen in FIG. 11. Plastic clamps 23 having a gutter tail complementary to the dovetail are inserted over the dovetails 22 and serve to hold the collar 20 together. The clamps 23 are held in place at the ends of the collar by a small bead 24 and an end wall 25.
