Patent nr. ... (ans. nr: 1406/77) angår en rørkobling med et hus, der har en gennemgående boring, hvis ender er indrettet til at optage en rørende, og hvor der i det mindste i den ene endedel er udformet en ringformet udsparing, hvis ene ende danner et ringfor-5 met anlæg, og i hvilken udsparing der er anbragt et ringformet låseorgan med en bøjelig indre keglestu bf ormet del, hvis inderste frie kant er indrettet til at indgribe med den ydre overflade af en i nævnte ene endedel af boringen optaget rørende for fastholdelse af denne, ligesom der i huset findes et ringformet eftergiveligt tætnings-10 organ til dannelse af en fluidumtætning mellem huset og nævnte rørende, og rørkoblingen ifølge det nævnte patent er ejendommelig ved, at tætningsorganet er anbragt i den ringformede udsparing, at der mellem tætningsorganet og låseorganets keglestubformede del og i hovedsagen koaksialt dermed er anbragt et stift ringformet afstands-15 organ, hvis ender er indrettet til at ligge an mod henholdsvis tætningsorganet og låseorganets keglestubformede del, og at låseorganets keglestubformede del, tætningsorganet og det mellemliggende afstandsorgan er aksialt forskydeligt inde i den ringformede udsparing i retning mod og bort fra det ringformede anlæg. En sådan kobling kan 20 ikke alene anvendes til sammenkobling af metalliske og ikke-metalliske, i hovedsagen stive rør, men også til sammenkobling af bøjelige rør, der kan anvendes ved høje temperaturer og tryk uden at glide ud af eller blive adskilt fra den rørkobling, hvormed de er forbundet.Patent No. ... (application no. 1406/77) relates to a pipe coupling with a housing having a through bore, the ends of which are arranged to receive a pipe and where at least one end part is formed an annular recess, one end of which forms an annular abutment, and in which recess is provided an annular locking member with a flexible inner cone bf shaped part, the inner free edge of which is arranged to engage the outer surface of an said one end portion of the bore received tubing to retain it, as well as an annular resilient sealing means for forming a fluid seal between the housing and said pipe, and the pipe coupling of said patent is characterized in that the sealing member is disposed in the annular recess that a rigid annular spacer is arranged between the sealing member and the cone-shaped portion of the locking member and substantially coaxially therewith, the ends of which are arranged to abut respectively show the sealing member and the cone-shaped member of the locking member, and that the cone-shaped member of the locking member, the sealing member and the intermediate spacer are axially displaceable within the annular recess towards and away from the annular abutment. Such coupling can be used not only for coupling of metallic and non-metallic, generally rigid tubes, but also for coupling flexible tubes which can be used at high temperatures and pressures without slipping out or being separated from the tubular coupling. with which they are connected.

Formålet med den foreliggende opfindelse er at tilvejebringe en fordel-25 agtig udførelsesform for den i hovedpatentet beskrevne rørkobling, og rørkoblingen ifølge opfindelsen er ejendommelig ved, at afstandsorganet ved sin mod låseorganets keglestubformede del vendende ende har en keglestubformet flade, der kan bestemme hældningen for den keglestubformede del, når det indre af huset sættes under fluidum-30 tryk. Det indre fluidumtryk i huset vil virke i retning af at presse rørenderne bort fra hinanden, hvorved den keglestubformede del af de tilhørende låseorganer vil blive bøjet i retning mod en stilling, i hvilken de står vinkelret på rørendernes længdeakse, hvorved låseorganerne tvinges i endnu kraftigere indgreb med rørenderne. Den 35 keglestubformede flade på afstandsorganet hindrer, at låseorganets keglestubformede del under indvirkning af det indre fluidumtryk bøjes så kraftigt, at indgrebet med rørenderne igen formindskes.The object of the present invention is to provide an advantageous embodiment of the pipe coupling described in the main patent, and the pipe coupling according to the invention is characterized in that the spacer at its end facing the cone-stub-shaped part has a cone-shaped surface which can determine the inclination for it. cone-shaped part when the interior of the housing is put under fluid pressure. The internal fluid pressure in the housing will act towards pushing the pipe ends away from one another, whereby the cone-shaped portion of the associated locking means will be bent towards a position in which they are perpendicular to the longitudinal axis of the pipe ends, thereby forcing the locking means into even stronger force. with the pipe ends. The cone-stub-shaped surface of the spacer prevents the cone-stub-shaped portion of the locking member from bending so strongly under the action of the internal fluid pressure that the engagement with the pipe ends is again reduced.

Opfindelsen vil i det følgende blive nærmere forklaret under henvisning til tegningen, på hvilken fig. 1 viser set i perspektiv en udførelsesform for koblingen i monteret tilstand, idet dele af koblingen og de dermed forbundne rør af 5 illustrative grunde er vist i snit, fig. 2 et længdesnit i den i fig. 1 viste kobling, hvor rørledningen ikke står under tryk, fig. 3 et længdesnit i den i fig. 1 viste kobling, men med rørledningen stående under tryk, og 10 fig. 4 et tværsnit efter linjen 13-13 i fig. 3.The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 is a perspective view of an embodiment of the coupling in the mounted state, parts of the coupling and the associated pipes being shown for 5 illustrative reasons in section; 2 is a longitudinal section in the embodiment of FIG. 1, where the pipeline is not pressurized; FIG. 3 is a longitudinal section in the embodiment of FIG. 1, but with the pipeline under pressure, and FIG. 4 is a cross-sectional view taken along line 13-13 of FIG. Third

Den på tegningen viste udførelsesform for koblingen anvendes til at forbinde to ens rør 50 med hinanden og omfatter to sæt af samarbejdende tætninger 26, afstandsringe 28 og låseringe 30. Hvert sæt bestående af en tætning, en afstandsring og en låsering virker ved 15 sit indgreb med røret på i hovedsagen samme måde som tætningen, afstandsringen og låseringen ved den i fig. 6 og 7 i hovedpatentet viste udførelsesform. Hoveddelen 10 har et par rørformede dorndele 58, der er koncentriske med hoveddelens boring 14, og som integrerende dele strækker sig ud fra anlæggene 18. Når et rør 50 indføres 20 i den ene ende af hoveddelen 10, omslutter den med sin ende 52 stramt den deriværende dorndel 58 således, at enden af røret 52 ligger an mod brystet 18. På denne måde tjener hver dorndel 58 som et centreringsorgan for røret, når dette indsættes i koblingen. Denne udførelsesform for hoveddelen 10 kan som beskrevet i forbindelse med 25 de i hovedpatentet omtalte udførelsesformer være forsynet med en kontinuerlig, forsat ringformet skulder eller et bryst 20, eller den kan som vist have et antal med indbyrdes perifer afstand anbragte, radialt forløbende ribber 60, hvis endeflader 62 samarbejder til dannelse af et anlæg, der funktionelt svarer til anlægget 20 ved de i 30 hovedpatentet beskrevne udførelsesformer. Ved den på tegningen viste udførelsesform anvendes ribberne 60 i stedet for en massiv, ringformet skulder med det formål at formindske den materialemængde, der indgår i hoveddelen 10.The embodiment of the coupling shown in the drawing is used to connect two identical pipes 50 to each other and comprises two sets of cooperating seals 26, spacer rings 28 and locking rings 30. Each set consisting of a seal, a spacer ring and a locking ring acts upon its engagement with the tube in substantially the same manner as the seal, spacer and locking ring of the one shown in FIG. 6 and 7 in the main patent embodiment. The body portion 10 has a pair of tubular mandrel portions 58 which are concentric with the bore portion 14 of the body portion and which integrate portions extend from the abutments 18. When a tube 50 is inserted 20 at one end of the body portion 10, with its end 52 tightly enclosing it. derivative mandrel portion 58 such that the end of the tube 52 abuts the chest 18. In this way, each mandrel portion 58 serves as a centering member for the tube as it is inserted into the coupling. This embodiment of the body portion 10 may, as described in connection with the embodiments referred to in the main patent, be provided with a continuous offset annular shoulder or chest 20, or it may have, as shown, a number of spaced radially extending ribs 60, the end faces 62 of which cooperate to form a plant which functionally corresponds to the plant 20 in the embodiments described in the 30 main patent. In the embodiment shown in the drawing, the ribs 60 are used instead of a solid annular shoulder for the purpose of reducing the amount of material contained in the main part 10.

En låsering 30 er anbragt nærmest ved ribberne 60's endeflader 62, 35 medens en tætning 26 er anbragt nærmest ved anlægget 22 på hver af 3A locking ring 30 is arranged closest to the end faces 62 of the ribs 60, while a seal 26 is placed closest to the abutment 22 on each of the 3

hættedelene 12, og mellem hver låsering og hver tætning er der anbragt en afstandsring 28. Når et rør 50 indføres i koblingen, vil dette rør ligesom ved den i fig. 6 og 7 i hovedpatentet viste udførelsesform for koblingen ikke komme i berøring med den inderste kant 46 5 på låseringen 30's keglestubformede del 40, før det har passeret tætningen 26. I fig. 2 er rørene 50 vist i en tilstand, hvor de ikke står under tryk. Når der i rørene 50 indføres en under tryk stående væske, vil de blive tvunget en lille smule bort fra anlæggene 18 på husets hoveddel 10, og den rørindgribende keglestubformede del 40 på 10 hver af låseringene 30 vil sammen med det rør, den omslutter, blive forskudt til en i hovedsagen tværgående, rørindgribende stilling, der er vist i fig. 3, hvorved rørene endnu kraftigere sammenlåses inde i koblingen. Indkrængning af den keglestubformede del 40 på hver af låseringene hindres ved, at den ligger an mod den skrå kant 36 på 15 den tilgrænsende stive afstandsring 28. Den afrundede kant 38 på hver af afstandsringene vil blive ført ind i den skål, der dannes af læbedelen 32 på den tilgrænsende tætning 26, hvorved denne tætning fastkiles og presses i endnu fastere tætnende indgreb mellem koblingshuset og det omsluttede rør.the spacer portions 12, and between each locking ring and each seal a spacer ring 28 is disposed. 6 and 7 of the main patent embodiment, the coupling does not come into contact with the inner edge 46 5 of the cone-shaped portion 40 of the locking ring 30 before it has passed the seal 26. In FIG. 2, the pipes 50 are shown in a state where they are not pressurized. When a pressurized fluid is introduced into the pipes 50, they will be forced slightly away from the abutments 18 on the body portion 10, and the tube engaging cone-shaped portion 40 of 10 each of the locking rings 30, together with the tube it encloses, will be offset to a generally transverse, tube engaging position shown in FIG. 3, whereby the tubes are locked even more tightly within the coupling. Intrusion of the cone-shaped portion 40 on each of the locking rings is prevented by abutting the inclined edge 36 of the adjacent rigid spacer ring 28. The rounded edge 38 of each of the spacer rings will be inserted into the bowl formed by the lip portion. 32 on the adjacent seal 26, whereby this seal is wedged and pressed into even firmer sealing engagement between the coupling housing and the enclosed pipe.

20 En dorndel 58 og eventuelt også ribber 60 som dem, der anvendes i forbindelse med den på tegningen viste udførelsesform for koblingen, kan anvendes i forbindelse med en hvilken som helst af de i hovedpatentet beskrevne udførelsesformer til brug i forbindelse med den med gevind forsynede del af boringen 14. Ved sådanne koblinger kan 25 et rør 50 forbindes med en med gevind forsynet fitting eller et med gevind forsynet rør.A mandrel part 58 and optionally also ribs 60 such as those used in connection with the embodiment of the coupling shown in the drawing can be used in connection with any of the embodiments described in the main patent for use in connection with the threaded part. of such bore 14. In such couplings, a pipe 50 may be connected to a threaded fitting or a threaded pipe.

Ved hver af de ovenfor beskrevne udførelsesformer for koblingen ifølge opfindelsen er det den hurtige, men kontrollerede bevægelse af låseringen 30's keglestubformede del 40 til et fast bidende indgreb 30 med yderfladen af det indførte rør, idet låseringen hindres i at blive totalt ombøjet, der bevirker, at røret fastgøres i koblingen. Selv om låseringsdelen 40 kunne standses af hættedelen 12 eller af afstandsringen 28 i en retviklet rørindgribende stilling, foretrækkes det, at delen 40 bringes til at indgribe med det indførte rør under en frem-35 adrettet vinkel, fx på mellem 5 og 30° afhængig af koblingens stør-In each of the above described embodiments of the coupling according to the invention, it is the rapid but controlled movement of the cone-shaped portion 40 of the locking ring 30 to a fixed biting engagement 30 with the outer surface of the inserted tube, preventing the locking ring from being completely bent, causing that the tube is attached to the coupling. Although the locking member 40 could be stopped by the cap member 12 or by the spacer ring 28 in a straight-wound tube engaging position, it is preferred that the member 40 be engaged with the inserted tube at an advanced angle, e.g., between 5 and 30 ° depending on coupling size
