Description

Die gegenständliche Erfindung betrifft einen Bausatz bestehend aus rohrförmigen Armaturen, insbesondere für die Wasserleitungs-, Sanitär-, Heizungs- und Gasleitungstechnik, mit zumindest einem T-förmigen Rohrelement, einem Ventilelement und einem Doppel rohrelement.The present invention relates to a kit made of tubular fittings, especially for water supply, Sanitary, heating and gas pipe technology, with at least a T-shaped pipe element, a valve element and a double pipe element.

Bekannte in der Wasserleitungs-, Sanitär-, Heizungs- und Gasleitungstechnik verwendete rohrförmige Armaturen, wie z.B. T-Stücke, Ventile und Doppelrohrstücke, sind an ihren beiden Enden jeweils mit einem Außengewinde ausgebildet, wobei deren Anschluß an eine bestehende Rohrleitung mit einer Muffe, welche z.B. durch Hanf abgedichtet wird, erfolgt. Dabei wird aus diesen einzelnen rohrförmigen Armaturen ein Rohrstrang zusammengesetzt, an welchen in weiterer Folge unterschiedliche Geräte, insbesondere Filter, Dosiergeräte oder Warmwassererzeuger, sowie Abzweigleitungen angeschlossen werden. Da diese einzelnen Armaturen unterschiedliche Längen aufweisen, bedingt dies für den Fall, daß in einem bestehenden Rohrstrang Änderungen vorgenommen werden müssen, entweder, daß dieser Rohrstrang vollständig zerlegt werden muß, um weitere Armaturen einsetzen zu können oder daß ein Teil der Armaturen entnommen wird und in der Folge andere Armaturen eingesetzt werden, wobei aufgrund dessen, daß diese dann unterschiedliche Längen aufweisen, zudem aufwendige Anpassungsarbeiten erforderlich sind.Known in water supply, sanitary, heating and gas pipe technology tubular fittings used, e.g. Tees, valves and double pipe pieces are on both of them Ends each formed with an external thread, the Connection to an existing pipeline with a sleeve, which e.g. is sealed by hemp. It will be from put together a pipe string for these individual tubular fittings, on which subsequently different devices, especially filters, dosing devices or water heaters, and branch lines can be connected. Because this individual Fittings have different lengths this in the event of changes in an existing pipe string must be made either that this tubing string must be completely disassembled to use further fittings to be able to or that part of the fittings is removed and in consequently other fittings are used, due to that these then have different lengths, moreover elaborate adjustments are required.

Der gegenständlichen Erfindung liegt demnach die Aufgabe zugrunde, einen Bausatz bestehend aus rohrförmigen Armaturen, insbesondere für die Wasserleitungs-, Sanitär-, Heizungs- und Gasleitungstechnik, zu schaffen, dessen einzelnen Bauelemente einen solchen konstruktiven Aufbau aufweisen, daß einerseits die Herstellung eines Leitungsstranges mit einer Vielzahl von rohrförmigen Armaturen für den Anschluß von unterschiedlichen Geräten und andererseits der Austausch von Armaturen in einem bestehenden Leitungsstrang wesentlich einfacher und damit in kürzerer Zeit und mit geringeren Kosten durchgeführt werden kann, als dies bislang der Fall ist. Dies wird erfindungsgemäß dadurch erzielt, daß das T-förmige Rohrelement, das Ventilelement und das Doppelrohrelement die gleiche axiale Länge aufweisen, und daß sämtliche diese rohrförmigen Armaturen an ihrem einen Ende mit einer Überwurfmutter und an ihrem anderen Ende mit einem dem Gewinde der Überwurfmutter entsprechenden Außengewinde ausgebildet sind.The object of the invention is therefore based on the object a kit consisting of tubular fittings, especially for the water pipe, plumbing, heating and Gas pipeline technology, to create its individual components have such a constructive structure that on the one hand the production of a wiring harness with a variety of tubular fittings for the connection of different Devices and on the other hand the exchange of fittings in one existing wiring harness much easier and therefore in be done in a shorter time and at a lower cost can than has been the case so far. This is according to the invention achieved in that the T-shaped tubular element, the valve element and the Double tube element have the same axial length, and that all these tubular fittings at one end with a union nut and at the other end with the thread of the union nut corresponding external threads are formed.

Die US-A-4 848 391 offenbart einen Rohrstrang, welcher aus einer Mehrzahl bzw. Vielzahl von identischen Armaturen, welche gleiche axiale Längen aufweisen, besteht. Diese Literaturstelle. offenbart jedoch keinen Bausatz, welcher eine Mehrzahl von unterschiedlichen Armaturen enthält, welche ungeachtet ihrer unterschiedlichen Ausbildung und der hierdurch erzielten unterschiedlichen Funktionen eine gleiche axiale Länge aufweisen. Zudem offenbart diese Literaturstelle keinen Rohrstrang, bei welchem die einzelnen Armaturen mittels Außengewinden und Überwurfmuttern miteinander verbunden sind. Vielmehr erfolgt deren Verbindung miteinander mittels mehrerer Zugstangen, welche sich über die gesamte axiale Länge sämtlicher Armaturen erstrecken. Soferne demnach das Erfordernis besteht, eine Armatur auszutauschen, muß gleichfalls die gesamte Einheit zerlegt werden.
Die Literaturstelle 'Polyethlene Pipework Systems' offenbart eine Vielzahl von Armaturen bzw. Bauteilen für sich. Diese Armaturen weisen jedoch weder die gleiche axiale Länge auf, noch sind sie an ihren axialen Enden einerseits mit einer Überwurfmutter und andererseits mit einem Außengewinde ausgebildet.
US-A-4 848 391 discloses a tubing string which consists of a plurality or a plurality of identical fittings which have the same axial lengths. This reference. however, does not disclose a kit which contains a plurality of different fittings which, regardless of their different design and the different functions achieved thereby, have the same axial length. In addition, this reference does not disclose a pipe string in which the individual fittings are connected to one another by means of external threads and union nuts. Rather, they are connected to one another by means of several tie rods, which extend over the entire axial length of all the fittings. If there is a need to replace a valve, the entire unit must also be dismantled.
The reference 'Polyethlene Pipework Systems' discloses a large number of fittings and components in themselves. However, these fittings have neither the same axial length, nor are they formed at their axial ends on the one hand with a union nut and on the other hand with an external thread.

Demgegenüber weisen bei einem erfindungsgemäßen Bausatz sämtliche rohrförmigen Armaturen die gleiche axiale Länge auf, wodurch in einem aus einem solchen Bausatz hergestellten Leitungsstrang, an welchen unterschiedliche Geräte angeschlossen sind, in sehr einfacher Weise ein Austausch einzelner Armaturen und damit der Ersatz von Geräten durch andere Geräte möglich ist. Somit besteht kein Erfordernis, diesen Rohrstrang vollständig zu zerlegen, sondern besteht vielmehr die Möglichkeit, eine oder mehrere aus einer Vielzahl von rohrförmigen Armaturen zu ersetzen. In contrast, all show in a kit according to the invention tubular fittings have the same axial length, which in one made from such a kit, on which different Devices are connected, an exchange in a very simple manner individual fittings and thus the replacement of devices by others Devices is possible. So there is no need to use this tubing string completely disassemble, but rather there is the possibility of one or to replace several of a variety of tubular fittings.

Vorzugsweise ist der quer abragende Rohrstutzen des T-förmigen Rohrelementen mit Kupplungselementen für eine Klauenkupplung ausgebildet. Weiters ist vorzugsweise der quer abragende Anschlußstutzen des Doppelrohrelementes mit Kupplungselementen für eine Klauenkupplung ausgebildet. Das Ventilelement ist vorzugsweise als Schrägsitzventil ausgebildet. Weiters kann eine der rohrförmigen Armaturen als Doppelrohrelement mit einem Kugelventil ausgebildet sein, wobei der quer abragende Anschlußstutzen mit Kupplungselementen für eine Klauenkupplung ausgebildet ist.Preferably, the transversely projecting pipe socket of the T-shaped pipe element designed with coupling elements for a dog clutch. Furthermore, the transversely projecting connecting piece of the double pipe element is preferably designed with coupling elements for a dog clutch. The valve element is preferably designed as an angle seat valve. Furthermore, one of the tubular fittings can be used as a double tube element a ball valve can be formed, the transversely projecting connection piece is designed with coupling elements for a dog clutch.

Vorzugsweise weisen solche rohrförmigen Armaturen, welche einen Durchmesser von 25mm (einem Zoll) aufweisen, eine axiale Länge von 120 mm auf.Such tubular fittings preferably have a Have a diameter of 25 mm (one inch) and an axial length of 120 mm.

Bei einem Leitungsstrang, insbesondere für die Wasserleitungs-, Sanitär-, Heizungs- und Gasleitungstechnik, welcher unter Verwendung von erfinerfindungsgemäßen rohrförmigen Armaturen zusammengesetzt ist, befindet sich vorzugsweise die Überwurfmutter am zuströmseitigen Ende und das Außengewinde am abströmseitigen Ende. Dies ist bei Leitungssträngen der Wasserleitungstechnik deshalb zweckmäßig, da das Anschlußrohr von Wasserzählern mit einem Außengewinde ausgebildet ist.In the case of a line, in particular for water supply, sanitary, Heating and gas pipe technology, which using inventions tubular fittings assembled is preferably the union nut on upstream end and the external thread on the downstream side The End. This is the case with piping systems used in water pipe technology therefore useful since the connection pipe of water meters with an external thread is formed.

In Fig. 3 ist ein Doppelrohrelement 3 dargestellt, welches aus einem ersten Rohrstutzen 3a und einem zweiten Rohrstutzen 3b besteht, wobei der Rohrstutzen 3a mit einer Überwurfmutter 31 sowie mit einem Haltering 32 und der Rohrstutzen 3b mit einem Außengewinde 33 ausgebildet sind. Der Rohrstutzen 3a bildet einen ersten Kanal 35, welcher in ein Innenrohr 36 eines quer abragenden Anschlußstutzens 30 führt. Das Außenrohr 37 des Anschlußstutzens 30 geht in einen durch das zweite Rohrstück 3b gebildeten Kanal 38 über. Der Anschlußstutzen 30 ist an seiner Außenseite mit Kupplungselementen 34 für eine Klauenkupplung ausgebildet.In Fig. 3, a double pipe element 3 is shown, which consists of a first pipe socket 3a and a second pipe socket 3b there, the pipe socket 3a with a union nut 31st and with a retaining ring 32 and the pipe socket 3b with a External threads 33 are formed.

The outer tube 37 of the Connection piece 30 goes into a through the second pipe section 3b formed channel 38 over. The connecting piece 30 is at his Outside with coupling elements 34 for a claw coupling educated.

In Fig. 4 ist gleichfalls ein Doppelrohrelement 3' dargestellt, welches der Ausbildung des Doppelrohrelementes gemäß Fig. 3 entspricht, wobei sich jedoch im Kanal 35 eine Ventilkugel 39, welche mit einem Kanal 40 versehen ist und welche in einem Ventilsitz 41 verdrehbar ist, befindet.4 also shows a double tube element 3 ', which the formation of the double tube element according to FIG. 3rd corresponds, but with a valve ball 39 in channel 35, which is provided with a channel 40 and which in a valve seat 41 is rotatable.

Sämtliche der in den Fig. 1 bis 4 dargestellten rohrförmigen Armaturen 1, 2 und 3 weisen die gleiche Länge auf, welche bei einem Rohrdurchmesser von einem Zoll 120 mm beträgt. Da weiters sämtliche diese rohrförmigen Armaturen mit einem identischen Außengewinde ausgebildet sind, welches dem Innengewinde der Überwurfmutter entspricht, sind sämtliche derselben aneinander anschließbar bzw. gegeneinander austauschbar. Mit derartigen Armaturen kann somit ein Leitungsstrang zusammengesetzt werden, an welchen eine Vielzahl von unterschiedlichen Geräten bzw. von Abzweigleitungen angeschlossen werden kann, wie dies nachstehend erläutert ist.All of the tubular shown in FIGS. 1 to 4 Faucets 1, 2 and 3 have the same length, which at a tube diameter of one inch is 120 mm. There further all of these tubular fittings with an identical External threads are formed, which corresponds to the internal thread of the Corresponds to union nut, all of them are together connectable or interchangeable. With such Valves can thus be put together a wiring harness on which a variety of different devices or Branch lines can be connected as follows is explained.

In Fig. 5 ist ein derartiger Leitungsstrang dargestellt. Dabei ist an ein Hauptabsperrventil 51 ein Doppelrohrelement 3 angeschlossen, an welches ein Wasserzähler 52 angekuppelt ist. Hierauf folgt ein Absperrventil 2, an welches ein T-förmiges Rohrstück 1 angeschlossen ist, an dessen Anschlußstutzen ein Ventilelement 2 angeschlossen ist, welches zu einer ersten Abzweigleitung führt. Hierauf folgen vier Doppelrohrelemente 3, an welche ein Filtergerät 53, ein Druckmindergerät 54, ein Rohrbruch-Sicherungsgerät 55 und ein Anschlußelement 56 für einen Wasserenthärter angekuppelt sind. Daran ist wiederum ein T-förmiges Rohrstück 1 angeschlossen, an dessen Anschlußstutzen ein Ventilelement 2 angefügt ist, welches zu einer zweiten Abzweigleitung führt. Darauf folgt ein weiteres Doppelrohrelement 3, an welches ein Dosiergerät 57 angekuppelt ist. Anschließend sind drei weitere T-förmige Rohrstücke 1 vorgesehen, welche jeweils über weitere Ventilelemente 2 zu weiteren Abzweigleitungen führen.Such a wiring harness is shown in FIG. 5. Here a double pipe element 3 is connected to a main shut-off valve 51, to which a water meter 52 is coupled. This is followed by a shut-off valve 2, to which a T-shaped one Pipe section 1 is connected, at its connecting piece Valve element 2 is connected, which to a first branch line leads. This is followed by four double tube elements 3, to which a filter device 53, a pressure reducing device 54 Pipe break belay device 55 and a connecting element 56 for a water softener is coupled. Again there is one T-shaped pipe section 1 connected to its connecting piece a valve element 2 is attached, which leads to a second branch line leads. Another double pipe element follows 3, to which a dosing device 57 is coupled. Subsequently three further T-shaped pipe sections 1 are provided, each of which via further valve elements 2 to further branch lines to lead.

Da sämtliche rohrförmigen Armaturen ein- und dieselbe Länge aufweisen und da sie an einem Ende mit einer Überwurfmutter und am anderen Ende mit einem dieser entsprechenden Gewinde ausgebildet sind, können aus einem bestehenden Leitungsstrang einzelne dieser rohrförmigen Armaturen entnommen und durch andere ersetzt werden. Da zudem die an diese rohrförmigen Armaturen angeschlossenen Geräte vorzugsweise über Klauenkupplungen angeschlossen werden, wird der Aufwand bei der Montage, d.h. bei der Herstellung eines derartigen Leitungsstranges, bzw. bei Wartungsarbeiten und beim Ersatz einzelner dieser Armaturen bzw. einzelner Geräte gegenüber herkömmlichen Leitungssträngen wesentlich vermindert. Da weiters aufgrund der gleichen Länge der einzelnen rohrförmigen Armturen die quer abstehenden Anschlußstutzen sich voneinander in jeweils gleichem Abstand befinden, weist eine derartige Installation einen regelmäßigen Aufbau auf. Da dies ein Erfordernis ist, welchem bei der Herstellung von neuen Anlagen entsprochen werden muß, kann diesem Erfordernis durch einen erfindungsgemäßen Bausatz in einfacher Weise entsprochen werden.Because all tubular fittings are one and the same length and because they have a union nut at one end and at the other end with one of these threads are trained from an existing wiring harness individual of these tubular fittings removed and through others will be replaced. Since also the tubular to this Fittings connected devices preferably over Claw couplings are connected, the effort at Assembly, i.e. in the manufacture of such Wiring, or during maintenance work and when replacing individual of these fittings or individual devices compared to conventional Cable strands significantly reduced. There further due to the same length of the individual tubular armatures the connecting pieces projecting transversely from each other Such an installation has the same distance a regular build up. As this is a requirement is the one that corresponds to the production of new systems must be able to meet this requirement by a corresponded to the kit according to the invention in a simple manner become.
