Description
Oppfinnelsen vedrører et forbindelses- henholdsvis tilknytningsstykke for glatte rør, særlig plastrør, bestående av en muffe med en i røret opptagende sylindrisk del og et tilsluttet, utvidet, men mot muffeenden konisk avsmalnende tetningskammer, hvori et tetningslegeme og en eventuelt lengdeslisset klemring er innsatt. The invention relates to a connection or connection piece for smooth pipes, in particular plastic pipes, consisting of a sleeve with a cylindrical part receiving in the tube and a connected, expanded, but conically tapering towards the end of the sleeve sealing chamber, in which a sealing body and a possibly longitudinally slotted clamping ring are inserted.
Slik forbindelsesstykker eller tilknytningsstykker har hittil hatt klemringer hvis innerflater danner rundtløpen-de riller med sagtannlignende profil, hvilke riller, som følge av tetningskammerets konisitet, graver seg inn i rørets overflate ved en strekkbelastning og tilveiebringer en strekkfast forbindelse mellom rør og muffe. Alt etter aksialskyvekraftens størrel-se vil disse skarpkantede, fortrinnsvis av metall fremstilte riller trenge mer eller mindre dypt inn i rørveggen og tilveiebringer rundt hele omkretsen til røret forløpende innsnitt. Disse omløpen-de innsnitt vil imidlertid i vesentlig grad redusere rørets fast-hetsegenskaper, slik at det ved høyere belastninger foreligger en fare for at røret beskadiges eller ødelegges. På grunn.-av virknin-gen til disse omløpende innsnitt, i tillegg understøttet av flyte-egenskapene til rørmaterialet, særlig når dette er plast, vil det ved de hittil kjente forbindelsesstykker eller tilknytningsstykker ofte komme til rissdannelser i rørveggen, særlig ved anvendelse av av metall fremstilte klemringer. De kjente metallklemringer egner seg riktignok godt for opptak av en strekkbelastning, på grunn av inntrengningsevnen overfor rørmaterialet, men medfører den meget ubehagelige ulempe som ligger i faren for rørbeskadigelser. Such connecting pieces or connecting pieces have hitherto had clamping rings whose inner surfaces form circumferential grooves with a sawtooth-like profile, which grooves, as a result of the sealing chamber's conicity, dig into the pipe's surface under a tensile load and provide a tensile-resistant connection between pipe and sleeve. Depending on the magnitude of the axial thrust, these sharp-edged grooves, preferably made of metal, will penetrate more or less deeply into the pipe wall and provide continuous incisions around the entire circumference of the pipe. These circumferential incisions will, however, significantly reduce the tube's strength properties, so that at higher loads there is a risk of the tube being damaged or destroyed. Due to the effect of these circumferential incisions, additionally supported by the flow properties of the pipe material, especially when this is plastic, cracks will often occur in the pipe wall with the hitherto known connecting pieces or connecting pieces, especially when using metal manufactured clamping rings. The known metal clamping rings are indeed well suited for absorbing a tensile load, due to their ability to penetrate the pipe material, but entail the very unpleasant disadvantage of the risk of pipe damage.
Por deformerbare rør finnes det også forbindel-seselementer og tilknytningselementer som bare består av et truk-ket platerør som for forbindelse med rørene har innvendige fremspring anordnet i grupper adskilt fra hverandre i omkretsretningen. Disse fremspring tilveiebringes ved hjelp av innsnitt som danner skråttstilte og over en del av røromkretsen forløpende tunger, idet disse tungene er beregnet til å'grave seg inn i rørveggen ved en tilsvarende strekkbelastning. Det oppstår da riktignok ingen omløpende innsnitt, men rørene<1>vil som følge av de i grupper sammenfattede fremspring, få meget ujevn belastning over omkretsen, og dette kan også føre til betraktelig fare for skader. Dessuten byr det enkle platerør ikkei på noen særlig sikker og strekkfast forbindelse og er i det h!ele tatt bare egnet for deformerbare og lite påkjente rør. For deformable pipes, there are also connection elements and connection elements which only consist of a drawn plate pipe which, for connection with the pipes, has internal projections arranged in groups separated from each other in the circumferential direction. These protrusions are provided by means of incisions which form slanted tongues extending over part of the pipe circumference, these tongues being intended to dig into the pipe wall under a corresponding tensile load. Admittedly, no circumferential incisions then occur, but the pipes<1>will, as a result of the protrusions combined in groups, receive a very uneven load over the circumference, and this can also lead to a considerable risk of damage. In addition, the simple plate pipe does not offer a particularly secure and tensile strength connection and is generally only suitable for deformable and lightly stressed pipes.
Hensikten med foreliggende oppfinnelse er å eli-minere de foran nevnte ulemper og å :tilveiebringe et forbindel-sesstykke eller tilknytningsstykke av den innledningsvis nevnte type, hvilket stykke muliggjør en srkker og strekkfast forbindelse uten fare for en beskadigelse ell'er rissdannelse av henholds-vi i røret. The purpose of the present invention is to eliminate the disadvantages mentioned above and to: provide a connecting piece or connection piece of the type mentioned at the outset, which piece enables a stronger and tensile-resistant connection without the risk of damage or cracking of the in the pipe.
Dette oppnår ifølge .'oppfinnelsen i det vesentlige ved at klemringens innerflate har flere separate, langs hele omkretsen fordelte, som mothaker fremspringende tenner. Ved hjelp av disse adskilte tenner unngår man en preging av ringinnsnitt i røroverflaten og røret belastes bare punktformet. Anordningen av et stort antall tenner vil pr. tann<bare gi en liten påkjenning på rørveggen, slik at man til tross for anvendelse av metallten-ner unngår en fare for skader eller,rissdannelse. Antall, form og anordningen av tennene kan tilpasses de gitte forhold, altså ut i fra rørmateriale, tannmaterialé, rørveggtykkelse, rørinner-trykk, aksialskyvekraften o.s.v., slik at man i ethvert tilfelle kan oppnå en optimal strekkfasthet for forbindelsen, med tilhøren-de optimal rørpåkjenning. According to the invention, this is essentially achieved by the inner surface of the clamping ring having several separate, barbed, projecting teeth distributed along the entire circumference. With the help of these separated teeth, the embossing of ring incisions in the pipe surface is avoided and the pipe is only loaded pointwise. The arrangement of a large number of teeth will per tines <only put a small stress on the pipe wall, so that despite the use of metal tines, a risk of damage or cracking is avoided. The number, shape and arrangement of the teeth can be adapted to the given conditions, i.e. based on pipe material, tooth material, pipe wall thickness, pipe internal pressure, axial thrust force, etc., so that in any case an optimal tensile strength for the connection can be achieved, with the associated optimal pipe stress .
i in
I og for seg kan tennene alt etter anvendt materi-ale og oppbygging av klemringen fremstilles på vilkårlig måte. Særlig gunstig er det imidlertid dersom man fremstiller klemringen av et plast-basislegeme eller lignende hvori det settes inn en platehylse som danner klemringens innerflate, idet tennene dan-nes av utpressede, skovlformede utbuktninger i kantområdene til hull eller slisser i platehylsen. På denne måten kan man ikke bare fremstille klemringer på en enkel og rasjonell måte, men man oppnår også en mulighet for uten spesielle tiltak å fremstille tennene og tilpasse disse til de ulike forhold. Videre har en slik tanntype den fordel at den har en god inntrengningsevne overfor rørmaterialet, på samme måte som en skovle, idet materialet ikke kan unnvike sideveis og inntrengningsdybden er gitt med ut-buktningens høyde. Detten medfører at man uten fare for riss kan oppnå en sikker fastholding av klemringen mot røroverflaten, slik at man får en virkelig strekkfast forbindelse. Alt etter valgt hullform eller slissform kan tennene avstemmes etter det anvendte rørmateriale, da det er kantene til disse hullene og slissene som danner skjærekantene eller skovlkantene til utbuktningene. For fremstilling av disse tennene stanser man i et platebånd ut hull eller slisser i ønsket fordeling og i ønsket form, hvoretter de angjeldende kantområder for hullene eller slissene trykkes ut slik at det oppstår skovlformede utbuktninger med bestemt dybde og form for skjærekantene. Et slik platebånd kan så tilskjæres, bøyes og settes inn i plastbasislegemet. Klemringen vil da være ferdig. In and of itself, depending on the material used and the structure of the clamping ring, the teeth can be produced in any way. However, it is particularly advantageous if the clamping ring is made from a plastic base body or the like into which a plate sleeve is inserted which forms the inner surface of the clamping ring, the teeth being formed by extruded, shovel-shaped protrusions in the edge areas of holes or slits in the plate sleeve. In this way, not only can clamping rings be produced in a simple and rational way, but it is also possible to produce the teeth without special measures and adapt them to the various conditions. Furthermore, such a tooth type has the advantage that it has a good penetration ability towards the pipe material, in the same way as a shovel, as the material cannot escape sideways and the penetration depth is given by the height of the bulge. This means that without the risk of cracking, you can achieve a secure holding of the clamping ring against the pipe surface, so that you get a truly tensile-resistant connection. Depending on the selected hole shape or slot shape, the teeth can be matched to the pipe material used, as it is the edges of these holes and slots that form the cutting edges or blade edges of the bulges. For the production of these teeth, holes or slots are punched out in a plate band in the desired distribution and in the desired shape, after which the relevant edge areas for the holes or slots are pressed out so that shovel-shaped protrusions with a specific depth and shape for the cutting edges occur. Such a plate strip can then be cut to size, bent and inserted into the plastic base body. The clamping ring will then be finished.
Por å oppnå en god fordeling av tennene og å sikre at tennenes angrepssteder mot røroverflaten ikke ligger for tett inntil hverandre og gir overlappende svekkende steder i røret, kan fordelaktig de hosliggende tenner være forskjøvet i forhold til hverandre i klemringens akseretning henholdsvis omkretsretning. In order to achieve a good distribution of the teeth and to ensure that the points of attack of the teeth against the pipe surface are not too close to each other and cause overlapping weak points in the pipe, the adjacent teeth can advantageously be offset in relation to each other in the clamping ring's axial direction or circumferential direction.
Oppfinnelsen skal beskrives nærmere under henvis-ning til tegningene hvor The invention shall be described in more detail with reference to the drawings where
fig. 1 viser et forbindelses- eller tilknytningsstykke med innsatt plastrør i aksialsnitt, og fig. 1 shows a connecting or connection piece with inserted plastic pipe in axial section, and
fig. 2.og 3, 4 og 5, 6 og 7, 8 og 9 samt 10 og 11 viser respektive lengdesnitt og grunnriss av et platebånd med forskjellige utforminger av utbuktningene for klemringens platehylse. fig. 2 and 3, 4 and 5, 6 and 7, 8 and 9 as well as 10 and 11 show respective longitudinal sections and ground plans of a sheet band with different designs of the bulges for the clamping ring's sheet sleeve.
Porbindelsesstykket eller tilknytningsstykket består av en muffe 1 som har en sylindrisk del som tjener til opptak av et plastrør 2. I tilslutning til den sylindriske del er det anordnet et utvidet, mot muffeenden konisk avsmalnende tetningskammer 4. Tetningskammeret 4 opptar et tetningslegeme 5 og en klemring 6. Klemringen 6 tilveiebringer den strekkfaste forbindelse mellom røret 2 og muffen 1. Klemringen 6 består av et plast-basislegeme 7 hvori det er innsatt en av et platemateriale frem-stilt hylse 8. I platehylsen 8 er det anordnet separate, innbyr-des forskjøvne, som mothaker fremspringende tenner 9- Ved strekkbelastning vil som følge av tetningskammerets 4 konisitet klemringen 6 presses mot røret 2 og tennene 9 vil trenge inn i rørets overflate slik at røret 2 holdes fast aksialt til tross for den glatte overflate. Som tenner tjener skovlformede utbuktninger 9a, 9b, 9c, 9d, 9e som er presset ut 'i kantområdene 10a, 10b, The pore connecting piece or connecting piece consists of a sleeve 1 which has a cylindrical part which serves to receive a plastic pipe 2. In connection with the cylindrical part, there is an extended sealing chamber 4, which tapers conically towards the end of the sleeve. The sealing chamber 4 accommodates a sealing body 5 and a clamping ring 6. The clamping ring 6 provides the tension-resistant connection between the pipe 2 and the sleeve 1. The clamping ring 6 consists of a plastic base body 7 into which a sleeve 8 made of a plate material is inserted. In the plate sleeve 8 there are arranged separate, mutually offset , which barbs projecting teeth 9- In the event of a tensile load, due to the conicity of the sealing chamber 4, the clamping ring 6 will be pressed against the pipe 2 and the teeth 9 will penetrate the surface of the pipe so that the pipe 2 is held firmly axially despite the smooth surface. Blade-shaped protrusions 9a, 9b, 9c, 9d, 9e which are pressed out in the edge areas 10a, 10b, serve as teeth.
10c, 10d, 10e i hull lia, lid eller slisser 11b, lic, lie i den av et platebånd 8a, 8b, 8c, 8d, 8e tilbøyede platehylse 8. Inn- 10c, 10d, 10e in holes lia, lid or slits 11b, lic, lie in the of a sheet band 8a, 8b, 8c, 8d, 8e inclined sheet sleeve 8. In-
i in
trengningsdybden til disse tennene defineres nøyaktig av utbukt-ningenes 9a - e høyde, og tennenes inntrengning påvirkes også av formen til skjærekantene 12a, 12b, 12c, 12d, 12e. Alt etter anvendt rørmateriale kan man således velge hullform henholdsvis slissform. Antall hull eller slisser;henholdsvis tenner er i tillegg til materialet også avhengig! av den strekkbelastning som forventes, da hver tann 9 bare skal overføre en bestemt belastning. the penetration depth of these teeth is precisely defined by the height of the protrusions 9a - e, and the penetration of the teeth is also affected by the shape of the cutting edges 12a, 12b, 12c, 12d, 12e. Depending on the pipe material used, you can thus choose a hole shape or slot shape. The number of holes or slots; or teeth, in addition to the material, also depends! of the expected tensile load, as each tooth 9 must only transmit a specific load.
Den nye klemring 6 sikrer en strekkfast fastholding av røret 2 i forbindelsesstykket eller tilknytningsstykket, uten fare for en rissdannelse i røret. Klemringen kan tilveiebringes med enkle midler og kan uten vanskeligheter tilpasses materi-alforhold, dimensjonsforhold og belastningsforhold. The new clamping ring 6 ensures a tensile retention of the pipe 2 in the connecting piece or connecting piece, without the risk of cracks forming in the pipe. The clamping ring can be provided with simple means and can be adapted without difficulty to material conditions, dimensional conditions and load conditions.
