Abstract

The universal pipe fitting has the ends of the pipes to be joined cut with a butt joint and located in a mounting flange. A special gasket is clamped between the pipe and the flange, with the design of the gasket depending on the type of pipe used. The gaskets comprise a small component with the major component common to all joints. For plastic pipes a flexible O ring is used and for metal pipes a cold welding ring which bites intot he pipe.

Description

Verschrautung für @unststoff- und @etai@rohre.Threading for @ unststoff- and @ etai @ tubes.

@nwendungsgebiet : die Erfindung betrifft Verse@raupu@@e@@ie @n der @asser- und eizungsi@stal@@-tion @nwendung finden, @a sie @@@kaile une war@e @@ien, sowie für @unststoffune @eta@@rchre mit geri@@@ @ustausei @itlch@ver@en@bar sind. Field of application: the invention relates to verses @ raupu @@ e @@ ie @n der @ aster- und eizungsi @ stal @@ - find @a sie @@@ kaile une war @ e @@ ien, as well as for @unststoffune @ eta @@ rchre with geri @@@ @ustausei @ itlch @ ver @ en @ bar.

@wech : @unststoffrohre werden neben den bisher @blichen @etallrohrlen immer mehr installier und je nach Verwendungszweck kombiniert. der hat diese kombini.erbare Verschraubung den Zweck, bei gleichen Unterteil, sowohl metall als auch í unststoffrohre zu verbinden oder durch eine @upplung den obergang von @etall- auf kunststoffrohr zu ermöglichen.@change: @plastic tubes are next to the previously @etallrohrlen more and more installed and combined depending on the intended use. he has this combinable The purpose of screwing is to use both metal and plastic pipes with the same lower part to be connected or the transition from metal to plastic pipe by means of a coupling to enable.

Stand der Technik : L's gibt eine Vielzahl von verschraubungen für @unststoff- und 'ietallrohre filr warme und kalte Medien jeweils mit speziellen Eigenscharften. Die Voratshaltung und der Arbeitsaufwand für @ombinationen beim @bergang von Hetall- auf @unststoffrohre ist grob.State of the art: L's are a variety of screw connections for Plastic and metal pipes for hot and cold media each with special Characteristics. The provision and the workload for @ombinations at @transition from metal to @plastic pipes is rough.

Eritik des Standes der Technik Die Vielzahl der Verschraubungen verursacht einen hohen ,srheitsaufwand für kombinierte Installation, bedingt durch vermehrte Verbindungen und somit @ichtungsrisiken.Eritik of the prior art causes the multitude of screw connections a high level of effort for combined installation, due to increased Connections and thus directing risks.

Auf gabe i.,er Erfindung liegt die @ufgabe zugrunde, die Vielzahl der Verschraubungen zu vermindern, die Lagerhaltung zu vereinfachen, @ichtungsrisiken weitgehend zu vermeiden und die Verschraubung auch an beengten Stellen zu handhaben.On task i. The invention is based on the task, the multitude to reduce the screw connections, to simplify the storage, @alignment risks largely to be avoided and to handle the screw connection even in confined spaces.

Lösung kiese Aufgabe wird dadurch gelöst, da bei gleichem Unterteil @etall- als auch kunststoffrohre durch Austausch der entsprechenden Verbindungsteile sicher verschraubt werden können.Solution This problem is solved because the lower part is the same @ Metal and plastic pipes by exchanging the corresponding connecting parts can be screwed securely.

Weitere Ausgestaltung: bas Verschraubungsoberteil hat anstelle des üblichen Sechskantprofiles ein Zwölfkantprofil und kann mit dein entsprechenden offenen Ringschlüssel besser betitigt werden.Further configuration: the upper screw part has instead of the usual hexagonal profile a twelve-sided profile and can with your corresponding open ring spanners are better operated.

@rzielbare Vorteile : Ger@te, Ventile und dergleichen können, anstatt mit Gewinde oder Lötenden, mit den Verschraubungsunterteilen versehen korden ohne Rücksicht auf das zu verwenden@e Robrmaterial.@Achievable advantages: Devices, valves and the like can instead with thread or soldering ends, provided with the screw connection lower parts cords without Consideration of the Robrmaterial to be used.

@@e Vorratshaltung wird einfacher, es sind weniger @i@btungsris@ken, der Übergang von @etall- auf @ unststoffrohr und umgekekchrt ist problemloser, Verteiler-und Geräteanschlüsse können kompakter ausgeführt werden. Storage becomes easier, there are fewer @ i @ btungsris @ k, the transition from @etall- to @unststoffrohr and vice versa is easier, distributor and Device connections can be made more compact.

Beschreibung der Ausführungsbeispiele : die ausführungsbeispiele der Erfindung sind in den Zeichnunglen dargestellt und werden im Folgenden näher beschrieben. Es zeigen Fig. 1 Verschraubung für Lunststoffrohr.Description of the exemplary embodiments: the exemplary embodiments of the Invention are shown in the drawings and are described in more detail below. It shows Fig. 1 screw connection for plastic pipe.

Fig. 2 Verschraubung für Metallrohr mit Schneidring. Fig. 2 Screw connection for metal pipe with cutting ring.

Fig. 3 Verschraubung für Metallrohr mit Lötfitting. Fig. 3 Screw connection for metal pipe with solder fitting.

@e Verschraubung Fig. l, für kunststoffrohre besteht aus einem Unterteil, einem Oberteil, einem @lemmring aus Metall oder Runststoff und der O-Ringdichtung. @e screw connection Fig. l, for plastic pipes consists of a lower part, an upper part, an @lemmring made of metal or plastic and the O-ring seal.

@a @ unststoffrohre bei gleichem Außendurchmesser auch verschiedene Wandstärken und alle Maße Tolleranzen haben, ist die @ lemmung und Dichtung konstruktiv für den Außendurchmesser bestimmt. Las Unterteil kann sowohl für hunststoffrohre, als auch für metallrohre für die Verbindung verwendet werden. @a @ plastic tubes with the same outer diameter also different ones Wall thicknesses and all dimensions have tolerances, the lock and seal are constructive intended for the outside diameter. The lower part can be used for plastic pipes, as well as metal pipes can be used for the connection.

er Klemmring für Runststoffrohre ist an beiden inden kegelig und auf ca. 2/3 der Länge mehrfach geschlitzt. Die geschlitzte Seite hat innen eine Sägenzahnung zur klemmung des iunststoffrohres. Die Ringnut gewährleistet eine sichere Federung der Segmente beim Aufschieben auf das Kunststoffrohr und bei der Klemmung. he clamping ring for plastic pipes is tapered on both indene and Slit several times over approx. 2/3 of the length. The slotted side has an inside Saw teeth for clamping the plastic pipe. The ring groove ensures a safe The segments spring when they are pushed onto the plastic tube and when they are clamped.

Die glatte nicht geschlitzte Unterseite dichtet durch Pressung des C-Ringes zwischen Unterteil und Rohr. Der kugelsitz begrenzt die Zusammendrückung und vermeidet somit Zerstörung des 0-Ringes. The smooth, non-slotted underside seals by pressing the C-ring between the lower part and the pipe. The ball seat limits the compression and thus avoids destruction of the O-ring.

Bei der Verwendung von Metallrohren kann entweder ein Schneidring oder ein Lötfitting verwendet werden. Fig. 2 zeigt die Verwendung des Schneidringes anstelle des Klemmringes und der Ringdichtung, Fig. 3 zeigt die Anwendung eines Lötfittings bei Verwendung desselben Unterteiles.When using metal pipes, either a cutting ring or a solder fitting can be used. Fig. 2 shows the use of the cutting ring instead of the clamping ring and the ring seal, Fig. 3 shows the application of one Solder fittings when using the same lower part.

taille Oberteilausführungen haben außen ein iwölfkantprofil für das Anziehen mit einem Ringschlüssel.Waist bodice designs have a twelve-point profile on the outside for the Tighten with a ring spanner.
