Abstract

The pipe joint proposed includes a connector (1) with at least one spigot (2, 2', 2") on which the end (6) of a pipe made of thermoelastic, cross-linked polyolefin is fixed by opening out and self-reforming to form a secure, gastight joint. The spigots (2, 2', 2") have a surface feature (3, 3', 3") and, beyond it, an extension (4, 4', 4") with chamfered end (5, 5', 5").

Description

Oblasť technikyTechnical field

Vynález sa týka potrubnej spojky na vyhotovenie pevných a tesných spojov pre potrubia, ktorá má najmenej jednu pripojovaciu časť so štruktúrovaným povrchom.BACKGROUND OF THE INVENTION The present invention relates to a pipe coupling for making rigid and tight joints for pipes having at least one structured surface connection portion.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Zo zverejnenej európskej patentovej prihlášky čísloFrom European Patent Application Publication No.

530 387 je známe, že pevné a plynotesné potrubné spoje rúr s rúrami z materiálu ako je stredne hustý, vysokohustý alebo termoelastický, zosieťovaný polyolefín, je možné pri teplote okolia vyrobiť tak, Že rúrový koniec sa reverzibilne rozšíri a nasunie sa na pripojovaciu časť potrubnej spojky. K tomu sa bežne používa rozperný tŕň. Materiál zvlášť termoelastický zosieťovaný polyolefín podlieha aj pri týchto podmienkach samovolnému spätnému preformovaniu sa do pôvodného, stavu, ktoré aj pri teplote okolia prebieha dostatočne rýchlo, aby sa pó rozšírení vytvorilo pevné a plynotesné spojenie s potrubnou spojkou. Pevné a plynotesné spojenie sa dosahuje pomocou štruktúry povrchu pripojovacej časti, aby sa rozšírený rúrový í koniec pri samovolnom spätnou pretvarovaní stiahol okolo nej, takže sa vytvorí velkoplošné velmi tesné spojenie medzi rúro' vým koncom a pripojovacou časťou potrubnej spojky.No. 530,387, it is known that rigid and gas-tight pipe joints of pipes such as medium dense, high density or thermoelastic crosslinked polyolefin can be made at ambient temperature by expanding the pipe end reversibly and slipping onto the connecting portion of the pipe connector . A spacer mandrel is commonly used for this purpose. Even under these conditions, the particularly thermoelastic crosslinked polyolefin material undergoes a spontaneous re-deformation to its original state, which, even at ambient temperature, proceeds fast enough to form a rigid and gas-tight connection to the pipe connector at ambient temperature. A rigid and gas-tight connection is achieved by means of the surface structure of the connection part, in order to contract the expanded tubular end during spontaneous deformation, so that a large-area very tight connection is formed between the pipe end and the connection part of the pipe coupling.

V praxi sa zistilo, že tieto známe, za pomoci rozperného tŕňa vyhotovené potrubné spojenia je možné vyhotoviť s dobrým výsledkom pri priemeroch rúry v oblasti od 50 mm a väčších. Pri menších priemeroch rúr vzniká problém tým, že toto úzke potrubie je relatívne ohybné a pri ohnutí potrubia môže sa rúrový koniec v malom rozsahu uvolniť od potrubnej spojky, čo stačí na spôsobenie nežiadúcej netesnosti v mieste spoja.In practice, it has been found that these known pipe connections made with the aid of an expanding mandrel can be produced with good results with pipe diameters in the range of 50 mm and larger. With smaller pipe diameters, the problem is that this narrow pipe is relatively flexible, and when the pipe is bent, the pipe end may loosen to a small extent from the pipe coupling, which is sufficient to cause an undesirable leak at the joint.

Podstata vynálezuSUMMARY OF THE INVENTION

Úloha vynálezu pozostáva v dosiahnutí potrubnej spojky, ktorá aj pri ohýbaní potrubia umožní dostatočne tesný potrubný spoj .SUMMARY OF THE INVENTION The object of the invention is to achieve a pipe coupling which allows a sufficiently tight pipe connection even when bending the pipe.

Podlá vynálezu sa táto úloha vyriešila tým, že pripojovacia časť má predĺženie, ktoré sa začína od štruktúrovaného povrchu a vytvára volný koniec pripojovacej časti.According to the invention, this object has been solved by providing the attachment portion with an extension that starts from the structured surface and forms the free end of the attachment portion.

Týmto spôsobom sa dosiahne, že na pripojovaciu časť potrubnej spojky natiahnutý rúrový koniec aj pri napnutí rúry ohybom zostáva pevne a plynotesné spojený s potrubnou spojkou.In this way, it is achieved that the pipe end, which is stretched to the connecting part of the pipe coupling, remains firmly and gastightly connected to the pipe coupling even when the pipe is bent.

Ďalšie výhodné vyhotovenia potrubných spojok podlá vynálezu sú vyznačené v podnárokoch.Further advantageous embodiments of the pipe couplings according to the invention are indicated in the subclaims.

Prehľad obrázkov na výkreseOverview of the figures in the drawing

Príklad vyhotovenia vynálezu je znázornený na obrázku a bude dalej podlá vzťažných označení podrobne vysvetlený a popísaný. Obrázok znázorňuje pohlad v reze potrubnej spojky podlá vynálezu.An example of an embodiment of the invention is shown in the figure and will be explained and described in detail below with reference numerals. The figure shows a cross-sectional view of a pipe coupling according to the invention.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Pri pohlade v reze na obraze 1 je možné rozoznať potrubnú spojku ú, v tvare T-kusu, ktorý má tri pripojovacie časti 2., 2/ a 2' ' · Každá pripojovacia časť 2, 2' a 2'' má štruktúru povrchu v tvare zosilnenia 3., 3' a 3' ' , ktoré ale môže byť Vytvorené ako drážka alebo vrúbok alebo podobne. V znázornenom vyhotovení zosilnenia 3., 3_' a 3/ sú strmo odsadené smerom do vnútra na vonkajšom priemere danej pripojovacej časti, kým smerom von prípadne smerom k volnému koncu sa zužujú. Vzniká taká štruktúra, ktorá ulahčuje nasunutie rúrového konca rampovým tvarom, ale na druhej strane vnútorným strmým od-, sadením zabraňuje dostatočným odporom spätnému stiahnutiu nasunutého rúrového konca.When viewed in cross-section in Figure 1, it is possible to discern a T-piece pipe connector 11 having three connecting portions 2, 2 / and 2 ''. Each connecting portion 2, 2 'and 2' 'has a surface structure in the shape of the reinforcement 3, 3 'and 3' ', but which may be formed as a groove or a notch or the like. In the embodiment shown, the reinforcements 3, 3 'and 3' are steeply spaced inwardly at the outer diameter of the connector portion while tapering outwardly or towards the free end. A structure is formed which facilitates the insertion of the pipe end by a ramp shape, but on the other hand by an internal steep offset, prevents sufficient resistances from retracting the inserted pipe end.

Na zosilnenia 3., 3.' a 3.' ' nadväzujú sa smerom von predĺženia 4.J Á' a 4'.', ktoré majú rovnaký vnútorný priemer, ako pripo jovacie časti 2, 2 'a 2' ' , ale ktorých vonkajší priemer v danom prípade, ako je znázornené, môže byť proti danej pripo jovace j časti nepatrne zmenšený. Volný koniec predĺžení 4, 4.' a 4' ' iná zošikmenie 5., 5.' , prípadne 5/ ' , na ulahčenie zavedenia do daného rúrového konca.For amplification 3., 3. ' a 3. ''extending outwardly of extensions 4.J.A' and 4 '.' having the same internal diameter as the connecting portions 2, 2 'and 2'', but whose outer diameter in the present case, as shown, may be slightly smaller. Free end of extensions 4, 4. ' and 4 '' other bevel 5., 5. ' 5, respectively, to facilitate introduction into the pipe end.

Potrubná spojka 1 je v znázornenom príklade vyhotovenia vytvorená ako T-kus; môže však miesto toho byť v tvare Y alebo inom, napríklad tiež jednoduchá rúrová spojka len s dvomi pripojovacími časťami. V najjednoduchšom prípade, môže byť pripojovacia časť vytvorená tiež z jedného zodpovedajúco vytvoreného rúrového konca, ked ide o priamy spoj medzi dvomi rúrovými koncami. V znázornenom príklade vyhotovenia pozostáva potrubná spojka z kovu, zvlášť z bronzu; môže ale byť z iných materiálov ako sklo alebo umelá hmota a tiež z termoelastického, zosieťovaného polyolefínu.The pipe coupling 1 is in the example shown in the form of a T-piece; however, it may instead be Y-shaped or otherwise, for example also a simple pipe coupling with only two connecting parts. In the simplest case, the connecting portion may also be formed from one correspondingly formed pipe end when it is a direct connection between the two pipe ends. In the illustrated embodiment, the pipe connector consists of metal, in particular bronze; however, it may be of materials other than glass or plastic and also of thermoelastic crosslinked polyolefin.
