Description

i DK 167035 B1in DK 167035 B1

Opfindelsen angår en rørforbindelse af den art, der består af en muffe og en indskydningsdel, især til plastrør, hvorved muffen har et indgangsstyrestykke og et endestyrestykke, samt en udvidelse, som tjener til at op-5 tage et tætningselement, og som består af en optagerille til en låsering, og et tætningskammer til en til tætningselementet hørende tætningskonus, som er forbundet med låseringen og i ikke samlet tilstand løber tragtfor-migt sammen i indskydningsringen. Låseringen har på sin 10 inderside en ringformig kompressionsrille, som i det mindste i retning mod indgangsstyrestykket har en affas-ning, der fortsætter i en skråt hældende flade hen til låseringens på indskydningssiden liggende side. Låseringen trykkes ved hjælp af indskydningsdelen via kompres-15 sionsrillen ind i optagerillen, der lige som låseringen har et trapezformet tværsnit. Kompressionsribben er, set i indskydningsdelens indskydningsretning, anbragt bag midtpunktet for optagerillens og låseringens trapezfor-mede tværsnit; og optagerillens ved indskydningssiden 20 liggende side er længere end låseringens modsvarende side. Sådanne rørforbindelser har vist sig at være særdeles anvendelige, f. eks. til rørledninger, som lægges i jorden, især som beskyttelses- eller føringsrør til kabler.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a pipe connection of the type consisting of a sleeve and an insertion member, in particular for plastic pipes, the sleeve having an input guide piece and an end guide piece, as well as an extension which serves to accommodate a sealing element and comprising a sealing element. a groove ring for a locking ring, and a sealing chamber for a sealing cone of the sealing element, which is connected to the locking ring and in a non-assembled state, funnel together in the insertion ring. The locking ring has on its inside an annular compression groove which at least towards the entrance guide piece has a bevel which continues in an inclined face towards the side of the locking ring on the insertion side. The locking ring is pressed by means of the insertion part via the compression groove into the receiving groove, which, like the locking ring, has a trapezoidal cross-section. The compression rib, as seen in the insertion direction of the insert, is positioned behind the center of the trapezoidal cross-section of the recess groove and locking ring; and the side of the receiving groove at the insertion side 20 is longer than the corresponding side of the locking ring. Such pipe connections have been found to be particularly useful, for example, for piping laid in the ground, especially as protective or guide pipes for cables.

Disse rørforbindelser er kendt under betegnelsen tofase-25 forbindelser, da det af låseringen og tætningskonusen bestående tætningselement opfylder en dobbelt funktion. Låseringens kompressionsribbe bevirker ved indskydning af indskydningsdelen først, at indskydningsdelen centreres, hvorefter tætningskonusen i hovedsagen bevirker, at der 30 opnås tætning. 1 den fra DE 28 00 406 kendte rørforbindelse er tætningskonusen godt nok et fleksibelt element, men udformet som et fuldt profil af gummi, der som bekendt ikke lader sig 35 komprimere. Dette medfører, at der skal anvendes forholdsvis store indskydningskræfter til at skyde indskydningsdelen ind i muffen. En reduktion af tætningskonusens DK 167035 B1 2 vægtykkelse ville medføre, at konusens tætnende virkning blev nedsat.These pipe connections are known under the term two-phase connections, since the sealing element of the locking ring and the sealing cone fulfills a dual function. The compression rib of the locking ring, by inserting the insertion member, first causes the insertion member to be centered, after which the sealing cone essentially causes the seal to be obtained. In the pipe connection known from DE 28 00 406, the sealing cone is probably a flexible element, but designed as a full profile of rubber which, as is well known, is not compressible. This means that relatively large push-in forces must be used to push the push-in part into the socket. A reduction in the wall thickness of the sealing cone DK 167035 B1 would cause the sealing effect of the cone to be reduced.

Formålet med opfindelsen er at anvise en rørforbindelse 5 af den indledningsvis nævnte art, hvormed indskydningskraften til indskydning af tætningskonusen bliver mindre end hidtil kendt, uden at konusens tætnende virkning samtidigt nedsættes.The object of the invention is to provide a pipe connection 5 of the kind mentioned above, by which the insertion force for insertion of the sealing cone becomes less than hitherto known, without simultaneously reducing the sealing effect of the cone.

10 Dette opnås ved, at rørforbindelsens tætningskonus består af to i forskellig radial afstand fra røraksen liggende tætningslæber, hvorimellem der i ikke samlet tilstand findes en ringformet afstandsspalte, og at den nærmest røraksen liggende tætningslæbe i indskydningsretningen 15 rager frem foran den ved muffesiden liggende tætningslæbe og er bøjet snabelformigt om til samme radiale afstand fra røraksen som denne. Desuden kan den ved muffesiden liggende tætningslæbe have mindst to ved muffesiden liggende ringformede tætningsribber. Ved en foretrukken ud-20 førelsesform kan den nærmest røraksen liggende tætningslæbe endvidere have mindst to ringformede tætningsribber, som ligger i området før den snabelformede ombøjning og vender ind mod røraksen.This is achieved by the fact that the sealing cone of the pipe joint consists of two sealing lips located at different radial distance from the pipe axis, between which there is an annular spacing gap, and that the sealing lip closest to the pipe axis protrudes in front of the sealing side and the sealing side. is bent flexibly to the same radial distance from the pipe axis as this one. In addition, the sealing lip at the sleeve side may have at least two annular sealing ribs at the sleeve side. Further, in a preferred embodiment, the sealing lip closest to the tubular shaft may have at least two annular sealing ribs which lie in the region prior to the cut-out bend and face the tubular shaft.

25 Ved rørforbindelsen ifølge opfindelsen forløber den ved muffesiden liggende tætningslæbe mere eller mindre parallelt med rør- eller muffeaksen, og dette gælder, uanset om tætningselementet er indlagt i rørforbindelsen eller ej. 1 modsætning hertil er den nærmest røraksen liggende 30 tætningslæbe trukket en lille smule tragtformet sammen på den ovenfor beskrevne måde. Denne nærmest røraksen liggende tætningslæbe kan ved indskydning af indskydningsdelen ved en foretrukken udførelsesform ifølge opfindelsen trykkes ind mod den ved muffesiden liggende tætnings-35 læbe. Det foretrækkes yderligere ifølge opfindelsen at indrette tætningselementet således, at den ringformede afstandsspalte begynder i overgangsområdet mellem låse- DK 167035 B1 3 ringen og tætningskonusen.In the case of the pipe connection according to the invention, the sealing lip lying at the sleeve side runs more or less parallel to the pipe or sleeve axis, and this applies regardless of whether the sealing element is inserted into the pipe connection or not. In contrast, the sealing lip closest to the pipe axis is pulled slightly funnel-shaped together in the manner described above. This sealing lip, which is closest to the pipe axis, can be pressed into the sealing lip located at the sleeve side by inserting the insertion member in a preferred embodiment of the invention. It is further preferred according to the invention to arrange the sealing element such that the annular spacer begins in the transition region between the locking ring and the sealing cone.

De ved hjælp af rørforbindelsen ifølge opfindelsen opnåede fordele består i, at der ved en given tætningsvirk-5 ning kræves langt mindre kraft end hidtil til indskydning af indskydningsdelen, uden at den tætnende virkning forringes derved. Denne kan endda forbedres yderligere ved, at afstandsringspalten fyldes med vand under tryk, således at vandets hydrostatiske tryk forøger tætningskraf-10 ten. Med henblik på at opnå en yderligere reduktion af indskydningskraften kan kompressionsribbens radiale højde reduceres i forhold til de kendte udførelsesformer.The advantages obtained by the pipe connection according to the invention consist in the fact that a given sealing effect requires far less force than hitherto for insertion of the insertion part, without impairing the sealing effect. This can even be further improved by filling the spacer ring with water under pressure so that the hydrostatic pressure of the water increases the sealing force. In order to achieve a further reduction of the shear force, the radial height of the compression rib can be reduced in relation to the known embodiments.

Opfindelsen forklares nedenfor, idet der beskrives en 15 blot eksempelvis udførelsesform under henvisning til tegningen, hvor fig. 1 viser et længdesnit gennem en rørforbindelse ifølge opfindelsen, og 20 fig. 2 i væsentlig større målestok et tværsnit gennem et til den i fig. 1 viste rørforbindelse hørende tætningselement i ikke indlagt tilstand.The invention is explained below, describing a mere exemplary embodiment with reference to the drawing, in which fig. 1 shows a longitudinal section through a pipe connection according to the invention, and FIG. 2 is, on a substantially larger scale, a cross-sectional view through one to the one shown in FIG. 1, the sealing member of the sealing element shown in the inlay condition not shown.

25 Den i figurerne viste rørforbindelse består af en muffe 1 og en indskydningsdel 2. Disse kan begge være udformet på tilsluttende rør, især plastrør, der anvendes som beskyttelses- eller føringsrør til kabler eller som rør til vand under tryk.The pipe connection shown in the figures consists of a sleeve 1 and an insertion part 2. These can both be formed on connecting pipes, in particular plastic pipes, which are used as protective or guide pipes for cables or as pipes for pressurized water.

Fig. 1 viser i øverste halvdel rørforbindelsen ifølge opfindelsen i ikke samlet tilstand under indskydning af indskydningsdelen, medens figurens nederste halvdel viser den samlede tilstand. Den i denne figur viste rørforbin-35 delse er f.eks. beregnet til tryk-vandrør. Muffen 1 omfatter på sin side et indgangsstyrestykke 3, et endestyrestykke 4, samt en udvidelse 5, 6 i to stykker. Disse DK 167035 B1 4 består af en optagerille 5 til en låsering 7 på et indlagt tætningselement af gummi, plast eller et lignende materiale. Udvidelsen omfatter desuden et tætningskammer 6 til en til tætningselementet hørende tætningskonus 8, 5 9, som er forbundet med låseringen 7. Et skråt forløbende overgangs stykke 10 forbinder udvidelsens 5, 6 to dele.FIG. 1 shows in the upper half the pipe connection according to the invention in non-assembled condition during the insertion of the insert, while the lower half of the figure shows the overall condition. The pipe connection shown in this figure is e.g. intended for pressure-water pipes. The sleeve 1, in turn, comprises an input guide piece 3, an end guide piece 4, and a two-piece extension 5, 6. These DK 167035 B1 4 consist of a receiving groove 5 for a locking ring 7 on a sealed element made of rubber, plastic or a similar material. The extension further comprises a sealing chamber 6 of a sealing cone 8, 59 which is associated with the sealing element 7, which is connected to the locking ring 7. A sloping transition piece 10 connects the two parts of the extension 5, 6.

Det siger sig selv, at tætningskonusen 8, 9 er udformet på låseringen 7. - Såvel optagerillen 5 som låseringen 7 har et trapezformet tværsnit.It goes without saying that the sealing cone 8, 9 is formed on the locking ring 7. - Both the receiving groove 5 and the locking ring 7 have a trapezoidal cross-section.

1010

Ved sammenlignende at betragte figur l's øverste - og ne-derste halvdel ser man, at låseringen 7 på sin inderside har en ringformet kompressionsribbe 11, der i det mindste i retning mod indgangsstyrestykket 3 er udformet med en 15 affasning 12, der omend med mindre hældning fortsætter hen til optagerillen 5's side 13. Dette medfører, at låseringen 7 i dette område har en større lysning end muffen l's indgangsstyrestykke 3 og indskydningsdelen 2's yderdiameter. Arrangementet er i øvrigt således, at låse-20 ringen 7 ved hjælp af indskydningsdelen 2 trykkes ind i optagerillen 5 under kompression og deformation af kompressionsribben 11 og under indskydningsdelen 2's indskydningsbevægelse slutteligt kommer til at indtage en effektivt fastlagt stilling i optagerillen 5. Til dette 25 formål ligger kompressionsribben 11 ved den viste udførelsesf orm bag ved midtpunktet KR i optagerillen 5's eller låseringen 7's trapezformede tværsnit set i indskydningsdelen 2*s indskydningsretning. Tætningskonusen består af to i forskellig radial afstand fra røraksen liggende tæt-30 ningslæber 8, 9. Mellem disse findes der, som vist i fig.By comparing the upper and lower half of Figure 1, it is seen that the locking ring 7 has on its inside an annular compression rib 11, which is formed at least towards the input guide piece 3 with a bevel 12, albeit with less inclination. continues to the side 13 of the recess groove 5. This causes the locking ring 7 in this area to have a larger illumination than the input guide piece 3 of the sleeve 1 and the outer diameter of the insertion part 2. Moreover, the arrangement is such that, by means of the insertion member 2, the locking ring 7 is pressed into the receiving groove 5 during compression and deformation of the compression rib 11 and during the insertion movement of the insertion member 2 will finally assume an effectively determined position in the receiving groove 5. For this purpose For the purpose, the compression rib 11 lies at the illustrated embodiment behind the center point KR in the trapezoidal cross-section of the receiving groove 5 or the locking ring 7 as seen in the insertion direction 2 *. The sealing cone consists of two sealing lips 8, 9 located at different radial distances from the pipe axis. Between these there are, as shown in FIG.

1 øverst og i fig. 2, i tætningselementets ikke indlagte tilstand en ringformet afstandsspalte 14. Arrangementet er således, at den nærmest røraksen liggende tætningslæbe 8 rager frem i indskydningsretningen foran den ved muffe-35 siden liggende tætningslæbe 9. Tætningslæben 8 er desuden bøjet snabelformigt om til samme radiale afstand fra røraksen som tætningslæben 9. Ved den viste udførelsesform DK 167035 B1 5 har den ved muffesiden liggende tætningslæbe 9 tre ved muffesiden liggende ringformede tætningsribber 15. Ved den viste udførelsesform har den nærmest røraksen liggende tætningslæbe 8 tilsvarende tre ringformede tætnings-5 ribber 17, som ligger i området før den snabelformede ombøjning 16, og som i dette tilfælde vender ind mod røraksen. Af fig. l’s nederste halvdel fremgår, at den nærmest røraksen liggende tætningslæbe 8 lader sig trykke ind mod den ved muffesiden liggende tætningslæbe 9, når 10 indskydningsdelen 2 indskydes. Den ringformede afstandsspalte 14 begynder i overgangszonen mellem låseringen 7 og tætningskonusen 8, 9.1 at the top and in FIG. 2, in the condition of the sealing element not inserted, an annular spacer 14. The arrangement is such that the sealing lip 8 closest to the pipe axis projects in the direction of insertion in front of the sealing lip 9 located at the socket side. The sealing lip 8 is further inclined to the same radial distance from pipe axis as the sealing lip 9. In the embodiment shown DK 167035 B1 5, the sealing lip 9 located at the sleeve side has three annular sealing ribs 15 located at the sleeve side. In the embodiment shown, the sealing lip 8 closest to the pipe axis has correspondingly three annular sealing ribs 17 which lie in the region before the coiled bend 16, which in this case faces the pipe axis. In FIG. In the lower half it can be seen that the sealing lip 8 closest to the pipe axis can be pressed against the sealing lip 9 located at the sleeve side when the insertion part 2 is inserted. The annular spacer 14 begins in the transition zone between the locking ring 7 and the sealing cone 8, 9.

Som det fremgår af fig. l’s øverste halvdel og især af 15 fig. 2, er der på tætningslæben 8, der, når rørforbindelsen ikke er samlet, løber tragtformet sammen i indskydningsretningen, udformet en ombøjning 16, som udvider sig konisk i forhold til tætningslæben 8, og som også, når rørforbindelsen ikke er samlet, ligger an mod tætnings-20 kammeret 6’s inderside. Dette medfører, at den ringformede afstandsspalte 14 er lukket, når rørforbindelsen ikke er samlet, og at løst siddende dele i jorden derfor ikke er i stand til at trænge ind i denne ringformede afstandsspalte 14. Når indskydningsdelen 2 er skudt helt 25 ind på plads, opstår der en labyrint tætning, idet tætningsribberne 15, 17 ligger an mod henholdsvis indskydningsdelen 2 ’ s yderside og tætningskammeret 6 ’ s inderside. Som det kun antydningsvis er vist i fig. 1, kan låseringen 7 yderligere have en støttering 18, som f. eks.As shown in FIG. l's upper half and especially of 15 fig. 2, on the sealing lip 8 which, when the pipe connection is not assembled, funnel-shaped together in the direction of insertion, a bend 16 which extends tapered in relation to the sealing lip 8 and which also, when the pipe connection is not assembled, abuts. the inside of the sealing chamber 6. This causes the annular spacer 14 to be closed when the pipe connection is not assembled and therefore loosely located parts of the ground are unable to penetrate this annular spacer 14. When the insertion member 2 is fully inserted 25, For example, a maze seal is formed, the sealing ribs 15, 17 abutting the outer side of the insertion member 2 and the inside of the sealing chamber 6, respectively. As only shown in FIG. 1, the locking ring 7 may further have a support ring 18, e.g.

30 kan bestå af fjederstål eller plast, og som f. eks. ved vulkanisering kan være indlejret i låseringen 7.30 may be made of spring steel or plastic and may be embedded in the locking ring 7 for example by vulcanization.

Den vinkel, hvormed låseringen 7's kompressionsribbe 11 er affaset, og affasningsvinklen for en modsvarende af-35 fasning 19 på indskydningsdelen 2 er valgt således, at de under indskydningsdelen 2’s indskydningsbevægelse i muffen 1 ligger uden for det selvlåsende område. Siden 13 er DK 167035 B1 6 længere end den modsvarende side 20 på låseringen. Det undgås herved, at indskydningsdelen 2 under indskydningen kommer til at støde direkte mod låseringen 7 efter at have passeret indgangsstyrestykket 3 og herved sætter sig 5 fast. Det ligger inden for opfindelsens ramme, at indskydningsdelen 2 kan fastklæbes til muffen i området ved indgangsstyrestykket 3 og endestyrestykket 4.The angle at which the compression rib 11 of the locking ring 7 is beveled and the bevel angle of a corresponding bevel 19 of the insertion member 2 is selected such that the insertion movement of the insertion member 2 in the sleeve 1 is outside the self-locking region. Since 13, DK 167035 B1 6 is longer than the corresponding side 20 of the locking ring. It is thereby avoided that the insertion part 2 during the insertion will strike directly against the locking ring 7 after passing the input guide piece 3 and thereby fixing 5. It is within the scope of the invention that the insertion portion 2 can be adhered to the sleeve in the region of the input guide piece 3 and the end guide piece 4.

For at sikre, at tætningslæben 8, når rørforbindelsen 10 ikke er samlet, kommer til at indtage en præcis på forhånd fastlagt position, er det ved store rørdimensioner formålstjenligt at indlejre en støttering 18 i låseringen 7. Denne støttering kan være udformet som en fjederstålsring 18 eller være fremstillet af et stift plastmateriale 15 eller lignende materiale. Støtteringen 18 virker stabiliserende og sikrer, at tætningslæberne 8, 9 virker sikkert som beskrevet, og at denne funktion ikke på uheldig måde bliver påvirket af, at låseringen 7 forskyder sig i optagerillen 5.In order to ensure that the sealing lip 8, when the pipe connection 10 is not assembled, will occupy a precisely predetermined position, it is expedient for large pipe dimensions to embed a support ring 18 in the locking ring 7. This support ring can be designed as a spring steel ring 18 or be made of a rigid plastic material 15 or similar material. The support ring 18 acts stabilizing and ensures that the sealing lips 8, 9 operate safely as described and that this function is not adversely affected by the locking ring 7 displacing in the receiving groove 5.
