Description

Vynález sa týka potrubnej spojky' na vyhotovenie pevných a tesných spojov na 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 pipe couplings having at least one structured surface connection portion.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Zo zverejnenej európskej patentovej prihlášky číslo 0 530 387 je známe, že pevné a plynotesné potrubné spoje rúr s rúrami z materiálu, ako je stredne hustý, vysokohustý alebo termoelastický, zosieťovaný polyolefm, 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 samovoľnému spätnému preformovaniu sa do pôvodného stavu, ktoré aj pri teplote okolia prebieha dostatočne rýchlo, aby sa po rozšírení vytvorilo pevné a plynotesné spojenie s potrubnou spojkou. Pevné a plynotesné spojenie sa dosahuje pomocou štruktúry povrchu pripojovacej časti, aby sa rozšírený rúrový koniec pri samovoľnom spätnom pretvarovaní stiahol okolo nej, takže sa vytvorí veľkoplošné veľmi tesné spojenie medzi rúrovým koncom a pripojovacou časťou potrubnej spojky.It is known from published European Patent Application No. 0 530 387 that rigid and gas-tight pipe joints of pipes with pipes of a material such as medium density, high density or thermoelastic crosslinked polyolefin can be produced at ambient temperature such that the pipe end is reversibly expanded and slid onto the connecting portion of the pipe coupling. A spacer mandrel is commonly used for this purpose. The material, in particular the thermoelastic crosslinked polyolefin, undergoes a spontaneous re-deformation even under these conditions, which, even at ambient temperature, proceeds sufficiently quickly to form a rigid and gas-tight connection to the pipe connector after expansion. The rigid and gas-tight connection is achieved by means of the surface structure of the connector portion to contract the expanded pipe end around the spline, so that a large-area, very tight connection is formed between the pipe end and the connector portion of the pipe coupling.

V praxi sa zistilo, že tieto známe, pomocou 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 uvoľniť od potrubnej spojky, čo stačí na spôsobenie nežiaducej netesnosti v mieste spoja.In practice, it has been found that these known pipe connections made by means of a spindle 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 undesirable leakage 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 present invention is to provide a pipe coupling which allows a sufficiently tight pipe coupling even when the pipe is bent.

Podľa vynálezu sa táto úloha vyriešila tým, žc pripojovacia časť má predĺženie, ktoré sa začína od štruktúrovaného povrchu a vytvára voľný koniec pripojovacej časti.According to the invention, this problem has been solved by having the attachment portion having an extension that starts from the structured surface and forms a 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 onto the coupling 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 podľa vynálezu sú uvedené v závislých nárokoch.Further advantageous embodiments of the pipe couplings according to the invention are set out in the dependent claims.

ne. V znázornenom vyhotovení zosilnenia 3, 3’ a 3” sú strmo posunuté smerom dovnútra na vonkajšom priemere danej pripojovacej časti, kým smerom von, prípadne smerom k voľnému koncu sa zužujú. Vzniká taká štruktúra, ktorá uľahčuje nasunutie rúrkového konca rampovým tvarom, ale na druhej strane vnútorným strmým posunutím zabraňuje dostatočným odporom spätnému stiahnutiu nasunutého rúrového konca.No. In the embodiment shown, the reinforcements 3, 3 ' and 3 ' are steeply displaced inwardly at the outer diameter of the connector portion while tapering outward or towards the free end. A structure is formed which facilitates the insertion of the tubular end by a ramp shape, but on the other hand by an internal steep displacement prevents sufficient resistance to retract the inserted tubular end.

Na zosilnenia 3, 3’ a 3” nadväzujú sa smerom von predĺženia 4, 4’ a 4”, ktoré majú rovnaký vnútorný priemer, ako pripojovacie časti 2, 2’ a 2”, ale ktorých vonkajší priemer v danom prípade, ako je znázornené, môže byť proti danej pripojovacej časti nepatrne zmenšený. Voľný koniec predĺžení 4, 4’ a 4” má zošikmenie 5, 5’, pripadne 5”, na uľahčenie zavedenia do daného rúrového konca.The reinforcements 3, 3 'and 3 ”are followed by outwards extensions 4, 4' and 4” having the same inner diameter as the connecting parts 2, 2 'and 2 ”, but whose outer diameter in the present case, as shown may be slightly reduced relative to the connection portion. The free end of the extensions 4, 4 ' and 4 ' has a 5 ', 5 ' or 5 ' slant to facilitate insertion 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 dvoma pripojovacimi časťami. V najjednoduchšom prípade, môže byť pripojovacia časť vytvorená tiež z jedného zodpovedajúco vytvoreného rúrového konca, keď ide o priamy spoj medzi dvoma rúrovými koncami. V znázornenom príklade vyhotovenia pozostáva potrubná spojka z kovu, zvlášť z bronzu; môže ale byť z iných materiálov ako sklo alebo plast a tiež z termoplastického, 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 can 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 thermoplastic crosslinked polyolefin.
