Description
i DK 167505 B1 oin DK 167505 B1 o
Den foreliggende opfindelse angår en førforbin-delse af den i indledningen til krav 1 angivne art.The present invention relates to a pre-connection of the kind set forth in the preamble of claim 1.
Fra DE patentskrift nr. 3 520 874 kendes en rørforbindelse af den indledningsvis nævnte art, som i prak-5 sis kun har vist sig egnet til plastrør med en vægtykkelse mindre end tre millimeter, idet ved større diametere tætheden ved temperaturforskelle ikke var sikret. Dette fremkom på grund af de forskellige varmeudvidelseskoefficien-ter for plast og metal, så at ved større temperaturfor-10 andringer, som de forekommer ved sanitærinstallationer med koldt- og varmtvandsledninger, er materialeudvidelsesforskellen ved plastvægtykkelser over tre millimeter så stor, at tætheden ikke længere er sikret.DE Patent Specification No. 3,520,874 discloses a pipe connection of the type mentioned in the preamble, which in practice has proved only suitable for plastic pipes with a wall thickness less than three millimeters, since at greater diameters the density of temperature differences was not ensured. This was due to the different coefficients of heat expansion for plastics and metal, so that with larger temperature changes as they occur for sanitary installations with cold and hot water pipes, the material expansion difference at plastic wall thicknesses over three millimeters is so large that the density is no longer secured.
Der kendes ganske vist tilsvarende rørforbindel-15 ser, som yderligere har som rundgummiringe udformede pakningsringe, som imidlertid ikke sikrer nogen tæthed i den fornødne samlede levetid.Admittedly, similar pipe connections are known which further have packing rings designed as round rubber rings, which, however, do not ensure any tightness during the required overall service life.
Formålet for den foreliggende opfindelse er tilvejebringelse af en rørforbindelse af den indledningsvis 20 nævnte art, som også ved rørvægtykkelser over tre millimeter sikrer en uklanderlig tætning uden ekstra pakninger og en fastholdelse af røret ved vekslende belastninger og temperatursvingninger under den fornødne levetid.The object of the present invention is to provide a pipe connection of the kind mentioned above, which also ensures, at pipe thicknesses over three millimeters, an impeccable seal without extra gaskets and a retention of the pipe by alternating loads and temperature fluctuations during the required life.
Dette opnås ved det i den kendetegnende del af 25 krav 1 angivne.This is achieved by the characterizing part of claim 1.
Ved den aftrappede udformning af støttebøsningen udformes én del til fastholdelse af plastrøret, en anden del til tætning. Herved opnås, at det pågældende parti kan udformes optimalt til den opgave, det skal løse. I .In the stepped configuration of the support bushing, one part is formed for holding the plastic pipe, another part for sealing. This ensures that the lot in question can be optimally designed for the task it is to solve. I.
30 det område, hvor røret tætnes, er vægtykkelsen reduceret til det nødvendige minimum, hvorved materialeudvidelsesforskellen ved temperaturvekslinger holdes så lille som muligt.In the area where the pipe is sealed, the wall thickness is reduced to the required minimum, thereby keeping the material expansion difference in temperature changes as small as possible.
yderligere foretrukne udførelsesformer for og 35 træk hos rørforbindelsen ifølge opfindelsen er angivet i de uselvstændige krav.further preferred embodiments and features of the pipe joint of the invention are set forth in the dependent claims.

Opfindelsen skal i det følgende beskrives nærmere ud fra udførelsesformer, idet der henvises til tegningen, på hvilken fig. 1 viser en rørforbindelse tildels i længde-5 snit med en konisk klemmebøsning, fig. 2 en anden udførelsesform for den i fig. 1 viste rørforbindelse, fig. 3 en rørforbindelse med en flerdelt klemmebøsning tildels i længdesnit, 10 fig. 4 et snit langs linien IV-IV i fig. 3, fig. 5 en anden udførelsesform for den i fig. 3 viste rørforbindelse i længdesnit og i større målestok, fig. 6 et delsnit langs linien VI-VI i fig. 5, og fig. 7 et deltværsnit langs linien VII-VII i fig. 5.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail from embodiments, with reference to the drawing, in which: FIG. 1 shows a pipe connection partly in longitudinal section with a tapered clamping sleeve; FIG. 2 shows another embodiment of the embodiment shown in FIG. 1, FIG. 3 shows a pipe connection with a multi-part clamping sleeve partly in longitudinal section; FIG. 4 is a section along line IV-IV of FIG. 3, FIG. 5 shows another embodiment of the embodiment of FIG. 3 is a longitudinal section on a larger scale, FIG. 6 is a partial section along line VI-VI of FIG. 5, and FIG. 7 is a partial cross-sectional view taken along line VII-VII of FIG. 5th
15 Fig. 1 viser en rørforbindelse, idet en tilslut ningsdel 1 er udformet som tilslutningsnippel, som ved hjælp af et indvendigt gevind 2 f.eks. kan forbindes med en fitting, et armatur eller et rør med udvendigt gevind.FIG. 1 shows a pipe connection, a connection part 1 being designed as a connection nipple, which by means of an internal thread 2 e.g. can be connected to a fitting, luminaire or pipe with external thread.
På den overfor det indvendige gevind 2 liggende side er 20 en støttebøsning 3 tæt og udrejeligt forbundet med tilslutningsdelen 1 ved hjælp af et gevind 4 og/eller en lodde- eller klæbeforbindelse. Tilslutningsdelen 1 har en konisk uddrejning 5, hvis begrænsende ringendeflade danner en anslagsflade 6 for et plastrør 7, som skal for-25 bindes, og for støttebøsningen 3. Støttebøsningen 3 er i yderkonturen trinformet udformet, idet det fra anslagsfladen 6 udgående parti 3a er udformet større i yderdiameter end det tilgrænsende parti 3b, hvis yderdiameter er lig med eller lidt større end den indvendige diameter 30 af plastrøret 7.On the side opposite to the internal thread 2, a support sleeve 3 is tightly and extensibly connected to the connection member 1 by means of a thread 4 and / or a solder or adhesive connection. The connection portion 1 has a tapered exit 5, the limiting ring end surface forming a stop surface 6 for a plastic tube 7 to be connected and for the support bushing 3. The support bushing 3 is formed in the outer contour step shape, the portion 3a projecting from the impacting surface 6 being formed. larger in outer diameter than the adjacent portion 3b, the outer diameter of which is equal to or slightly larger than the inner diameter 30 of the plastic tube 7.
Overgangen mellem de to partier 3a og 3b af støttebøsningen 3 er udformet konisk. I den koniske uddrej ning 5 er anbragt en ved yderomkredsen konisk klemmebøsning 8, som har en i længderetningen forløbende 35 slids. En på et udvendigt gevind 9 på tilslutningsdelen 1 påskruelig overløbermøtrik 10 har en ring 11, ved hjælp af hvilken klemmebøsningen 8 ved fastskruning af overlø DK 167505 B1 0 3 bermøtrikken 10 på grund af den koniske udformning bliver sammentrykket radialt, hvorved plastrøret 7 fastklemmes på støttebøsningen 3.The transition between the two portions 3a and 3b of the support bushing 3 is conical. In the tapered extension 5 is provided a conical clamping sleeve 8 at the outer circumference, which has a longitudinally extending 35 slot. An overflow nut 10 screwed onto an external thread 9 on the connection part 1 has a ring 11, by means of which the clamping sleeve 8, by screwing over the overlap 10 due to the tapered design, is radially compressed, whereby the plastic tube 7 is clamped to the support bushing. third
Den ydre omkreds af støttebøsningen 3 og den indre 5 omkreds af klemmebøsningen 8 er forsynet med omkredsmæssige profilriller, idet klemmebøsningen 8 og det i yderdiameter mindre parti 3b af støttebøsningen har savtandformede riller 12 hhv. 12a med afrundede kanter. Profilrillerne kan her f.eks. også være bølgeformet udformede.The outer circumference of the support sleeve 3 and the inner 5 circumference of the clamp sleeve 8 are provided with circumferential profile grooves, the clamp sleeve 8 and the smaller diameter 3b of the support sleeve having sawtooth grooves 12 and 10, respectively. 12a with rounded edges. Here, the profile grooves can e.g. also be wave-shaped.
10 På grund af de afrundede profilkanter bliver der i dette område, hvor træk- og bøjningsspændingerne optræder, kun frembragt små kærvspændinger. Partiet 3a er derimod på yderomkredsen forsynet med fine, skarpkantede tætningsriller 13.10 Due to the rounded profile edges, only small notch stresses are produced in this area where the tensile and bending stresses occur. The portion 3a, on the other hand, is provided with fine, sharp-edged sealing grooves 13 on the outer circumference.
15 Plastrøret 7, der skal forbindes, har ved ind- stiksenden en uddrejning 14, hvis inderdiameter er lig med eller lidt mindre end yderdiameteren af partiet 3a af støttebøsningen, og hvis længde og koniske overgang er tilpasset til støttebøsningen 3. Uddrejningen er større 20 end middelrørdiameteren, fortrinsvis er restvægtykkelsen S2 ved uddrejningen 1/3 til 1/4 af rørvægtykkelsen S^.The plastic tube 7 to be connected has at the insertion end a turning 14 whose inner diameter is equal to or slightly smaller than the outer diameter of the portion 3a of the support sleeve and whose length and tapered transition are adapted to the support sleeve 3. The expansion is greater than 20. the average pipe diameter, preferably the residual wall thickness S2 at the exit is 1/3 to 1/4 of the pipe wall thickness S 1.
Den beskrevne rørforbindelse anvendes fortrinsvis til tykvæggede plastrør, hvis vægtykkelse S·^ er lig med eller større end 3 mm.The described pipe connection is preferably used for thick-walled plastic pipes whose wall thickness S · is equal to or greater than 3 mm.
25 Det tyndvæggede rørparti 7a af indstikslængden danner det tætnende parti, idet materialeudvidelsesforskellen ved temperaturveksling på grund af den reducerede vægtykkelse er væsentlig mindre end ved det kraftoverførende klemmeparti, så at der også ved kraftig temperatur-30 veksling bestandig sikres en tæt rørforbindelse. Yderligere kan sikkerheden imod utæthed forbedres ved hjælp af en på røryderdiameteren mellem klemmebøsningen 8 og anslagsfladen 6 anbragt pakring 15 af plast.The thin-walled pipe portion 7a of the insertion length forms the sealing portion, the material expansion difference due to the reduced wall thickness due to the reduced wall thickness being substantially smaller than that of the force-transmitting clamping portion, so that a tight pipe connection is also always maintained at high temperature exchange. Further, the leakage resistance can be improved by means of a plastic packing ring 15 made of plastic on the tube diameter between the clamping sleeve 8 and the abutment surface 6.
Ved den i fig. 2 gengivne udførelsesform er kun 35 sammenspændingsorganet for klemmebøsningen anderledes ud formet. Tilslutningsdelen 1 har en ring 20, mod hvilken enIn the embodiment shown in FIG. In the illustrated embodiment, only the clamping member for the clamping bush is differently shaped. The connector 1 has a ring 20 against which one

0 4 med gevindboringer 22 forsynet, påskudt flange 21 ligger an. En anden, over plastrøret 7 påskudt flange 23 trækkes ved hjælp af spændeskruer 24 med en anlægsflade 25 imod klemmebøsningen 8, hvorved rørenden sammenspændes imod 5 støttebøsningen 3.0 4 with threaded bores 22 provided, flanged flange 21 abutting. Another flange 23 pushed over the plastic tube 7 is pulled by means of clamping screws 24 with a abutment surface 25 against the clamping bush 8, whereby the pipe end is clamped against the supporting bushing 3.
Tætningsvirkning og klemmevirkning frembringes som ved den tidligere beskrevne udførelsesform ved hjælp af partierne 3a og 3b i samvirke med klemmebøsningen 8.Sealing action and clamping effect are produced as in the previously described embodiment by means of portions 3a and 3b in cooperation with the clamping sleeve 8.
Den i fig. 3 og 4 viste udførelsesform for rør-10 forbindelsen har en omkredsmæssigt flerdelt udformet klemmebøsning 40, som ved yderomkredsen i det væsentlige er udformet cirkulærcylindrisk og ved hjælp af spændebånd 30 sammenspændes radialt imod det på støttebøsningen 3 påskudte plastrør 7.The FIG. 3 and 4, the tubular connection shown in Figures 3 and 4 has a circumferentially multi-shaped clamping sleeve 40 which is substantially circularly shaped at the outer circumference and is clamped radially against the plastic tube 7 projected onto the support sleeve 3 by clamping tape 30.
15 Klemmebøsningen 40 består fortrinsvis af seks segmentformede dele 41, som ved en omkredsmæssig ende har anslagsknaster 42. Anslagsknasterne er ved hjælp af anbringelsen af kærve 43 udformet fjedrende eller efter-givelige i omkredsretningen (se fig. 4).Preferably, the clamp bushing 40 consists of six segmental portions 41 having a circumferential end 42 at a circumferential end. The abutment bosses are resilient or resilient in the circumferential direction by the arrangement of notch 43 (see FIG. 4).
20 På grund af anlægget af anslagsknasten 42 i det ydre omkredsområde af den efterfølgende segmentformede del 41 opnås en ved hvert sted lige brede spalter 44 givet, ensartet fordelt beliggenhed af delene 41.Because of the abutment of the impact crank 42 in the outer circumferential region of the subsequent segment-shaped portion 41, a uniformly distributed slot is provided at each location, uniformly distributed location of the portions 41.
Ved sammenspænding af spændebåndene 30 ved hjælp 25 af skruer 31 bliver de enkelte, segmentformede dele 41 spændt ensartet radialt imod plastrøret 7. Herved deformeres anslagsknasterne 42, og spalterne 44 indsnævres ensartet, så at der også efter fastklemning af plastrøret stadig foreligger en omkredsmæssig ensartet forde-30 ling af delene 41. Dermed sikres også en langs hele omkredsen ensartet fordelt spændekraft. Ved anvendelsen af et antal spalter 44 kan disse også ved store tolerancer i rørdiametrene holdes forholdsvis små.By clamping the straps 30 by screws 31, the individual segment-shaped parts 41 are tensioned uniformly radially against the plastic tube 7. This deforms the impact lugs 42 and the slots 44 narrowed uniformly, so that even after clamping the plastic tube, a circumferentially uniform front is still present. -30 extension of the parts 41. This also ensures a uniform tensioning force along the entire circumference. When using a plurality of slots 44, these can also be kept relatively small even at large tolerances in the pipe diameters.
De to spændebånd 30 er anbragt i ved hjælp af om-35 kredsmæssigt forløbende ribber 45 dannede udsparinger 46.The two clamping straps 30 are arranged in recesses 46 formed by circumferentially extending ribs 45.
DK 167505 B1 0 5 På ribberne 45 formede fremspring 47 danner en snapforbindelse til påklemning af de enkelte, segmentformede dele 41 på spændebåndene 30, så at en enhed dannet af spændebåndene 30 og den af delene 41 bestående klemme-5 bøsning 40 kan skydes over plastrøret 7. Herved forenkles monteringen væsentligt.On the ribs 45, projections 47 on the ribs 45 form a snap connection for clamping the individual segment-shaped portions 41 on the clamping straps 30, so that a unit formed by the clamping straps 30 and the clamp-5 bushing 40 of the parts 41 can be pushed over the plastic pipe. 7. This greatly simplifies assembly.
De segmentformede dele 41 har ved den ene aksiale ende en indadrettet ring 48, som i monteret tilstand indgriber i en i tilslutningsdelen 1 anbragt ringnot 50, 10 hvorved enheden bestående af klemmebøsning 40 og spænde-bånd 30 er fikseret i aksial retning til tilslutningsdelen 1. Ved denne udførelsesform er tilslutningsdelen 1 fremstillet i ét stykke med støttebøsningen 3, idet støttebøsningen 3 svarende til den i fig. 1 og 2 viste udfø-15 relsesform udviser partierne 3a og 3b og de tilsvarende riller hhv. 12 og 13.The segment-shaped parts 41 have at one axial end an inwardly directed ring 48 which engages in a mounted state in a ring groove 50, 10, in which the unit consisting of clamping sleeve 40 and clamping belt 30 is fixed in axial direction to the connection part 1. In this embodiment, the connecting member 1 is made integrally with the support bushing 3, the support bushing 3 corresponding to the one shown in FIG. 1 and 2, the portions 3a and 3b and the corresponding grooves respectively show 12 and 13.
De segmentformede dele 41 af klemmebøsningen 40 har ved den indre omkreds tilsvarende riller 12a og 13a, som er anbragt liggende radialt overfor de på støttebøs-20 ningen anbragte riller fortrinsvis forsat en halv rilleafstand. Klemmeparti og tætningsparti svarer således til den i forbindelse med fig. 1 og 2 beskrevne udførelsesform.The segment-shaped portions 41 of the clamp sleeve 40 have, at the inner circumference, corresponding grooves 12a and 13a, which are arranged radially opposite the grooves arranged on the support sleeve 20, preferably a half groove spacing. Thus, clamping portion and sealing portion are similar to that of FIG. 1 and 2.
Ved anvendelse af to parallelle spændebånd 30 sikres det, at den radiale sammenpresning uafhængigt af 25 tolerancer optimalt kan påføres på tætnings- og klemme-partiet.By using two parallel clamps 30, it is ensured that, irrespective of 25 tolerances, the radial compression can be optimally applied to the sealing and clamping portion.
Delene 41 af klemmebøsningen 40 er fortrinsvis fremstillet af et plastmateriale, som dels er tilstrækkeligt hårdt til ved hjælp af rillerne at deformere plast— 30 røret, og som dels sikrer udformningen af en fjedrende anslagsknast 42.The portions 41 of the clamp sleeve 40 are preferably made of a plastic material which is sufficiently hard to deform the plastic tube by means of the grooves and which partly ensures the design of a resilient impact pad 42.
Ved den i fig. 5 til 7 viste udførelsesform består klemmebøsningen af mindst tre segmentformede dele 60 til mindre rørdiametre, idet der ved den viste udførelses-35 form til større rørdiametre er gengivet seks dele 60. De 0 6 DK 167505 ΒΊ segmentformede dele 60 er omkredsmæssigt anbragt i ensartet afstand fra hinanden, hvorved der fremkommer spalter 61.In the embodiment shown in FIG. 5 to 7, the clamping sleeve consists of at least three segment-shaped parts 60 for smaller pipe diameters, in the embodiment shown for larger pipe diameters six parts 60 are reproduced. The 0 6 DK 167505 ΒΊ segment-shaped parts 60 are circumferentially spaced slots 61 to form slots 61.
Til opretholdelse af en ensartet afstand er der ved endesiderne af de segmentformede dele 60 anbragt sprederinge 5 62 og 63, som er forsynet med i spalterne 61 indgribende, fjedrende fremspring 64. De fjedrende fremspring 64 er forsynet med affasninger 65, som ligger an imod affasede anlægsflader 66 på de segmentformede dele 60.In order to maintain a uniform distance, at the end sides of the segment-shaped parts 60, spacer rings 5 62 and 63 are provided, which are provided with resilient projections 64 engaging in the slots 61. The resilient projections 64 are provided with bevels 65 which abut the bevel. abutment surfaces 66 on the segment-shaped parts 60.
Ved sammenspænding af klemmebøsningen 40 ved hjælp 10 af spændebåndene 30 formindskes spalterne 61 ensartet, idet de to fjedrende fremspring 64 hvert sted trykkes noget sammen af de skrå anlægsflader 66.By clamping the clamp bushing 40 by means of the clamping straps 30, the slots 61 are uniformly reduced, the two resilient projections 64 being compressed at each location somewhat by the inclined abutment surfaces 66.
På den mod røret vendende endeside har de segmentformede dele 60 en i tværsnit tilnærmelsesvis cirkelfor-15 met ringvulst 67, på hvilken sprederingen 62 fastholdes i aksial retning indsnappet med en tilsvarende udsparing 68. Sprederingen 63 er i tværsnit udformet rektangulær og fastholdes aksialt mellem bøsningen 40 og en anlægsflade 51 på tilslutningsdelen 1 og radialt på et centreringssæde 2o 52 på tilslutningsdelen 1.On the end side facing the tube, the segmental parts 60 have a cross-sectional approximately circular annular bead 67 on which the spreader ring 62 is retained axially, with a corresponding recess 68. The spreader 63 is rectangular in shape and is held axially between the bushing 40. and a contact surface 51 on the connection portion 1 and radially on a centering seat 20o 52 on the connection portion 1.
Ved denne udføre ls es form er de segmentformde dele fortrinsvis fremstillet af messing, idet de to sprederinge 62 og 63 fortrinsvis er fremstillet af plastmateriale.In this embodiment, the segment-shaped parts are preferably made of brass, the two spreader rings 62 and 63 being preferably made of plastic material.
Sprederingene 62 og 63 sikrer ligeledes en om-25 kredsmæssig ensartet fordeling af delene 60, hvorved der også sikres en om hele omkredsen ensartet fordelt radial spændekraft.The diffusers 62 and 63 also ensure a circumferentially uniform distribution of the portions 60, thereby also ensuring a radially tensioning uniformly distributed throughout the circumference.
Den øvrige udformning af denne udførelsesform svarer til den i forbindelse med fig. 3 og 4 beskrevne .The other embodiment of this embodiment is similar to that of FIG. 3 and 4.
