Abstract
Description
Die Erfindung betrifft einen Fitting aus einem Gusswerk stoff wie er im Oberbegriff von Anspruch 1 gekennzeichnet ist.The invention relates to a fitting from a casting plant Substance as characterized in the preamble of claim 1 is.
Die bekannten gegossenen Fittings bzw. Formstücke zum Verbinden von Rohrleitungen, welche vorzugsweise aus Temperguss hergestellt sind, weisen eine quer zur jeweiligen Rohrachse runde Gestalt auf, wobei an dem mit einem Innengewinde versehenen Ende ein Verstärkungsrand bzw. Bördel angeordnet ist.The known cast fittings or fittings for Connecting pipes, which are preferably made of Malleable cast iron are produced, have a cross to each pipe axis round shape, with on the with an internally threaded end a reinforcing edge or flare is arranged.
Das feste Verschrauben mit einer Rohrleitung ist nur mit einer Rohrzange möglich, wodurch Beschädigungen der Zink- Beschichtung entstehen können. Ein Lösen des Fittings bei älteren Rohrleitungssystemen ist oft nicht ohne Beschädigung des Fittings möglich.Fixed screwing to a pipe is only possible with pipe wrench possible, which can damage the zinc Coating can arise. Loosening the fitting at Older piping systems are often not without damage of the fitting possible.
Aufgabe der vorliegenden Erfindung ist die Schaffung eines Fittings der eingangs genannten Art, welcher ohne Beschä digung montier- und demontierbar ist, als Gussteil gut entformbar ist und durch seine einfache Form rationell im Giessverfahren herstellbar ist.The object of the present invention is to create a Fittings of the type mentioned, which without is easy to assemble and disassemble, as a casting is demoldable and rational due to its simple shape can be produced in the casting process.
Erfindungsgemäss wird dies durch die kennzeichnenden Merk male von Anspruch 1 gelöst.According to the invention, this is achieved by the characterizing note male solved by claim 1.
Besonders vorteilhafte Ausführungsformen sind in den ab hängigen Ansprüchen gekennzeichnet.Particularly advantageous embodiments are in the pending claims.
Die Erfindung ist in mehreren Ausfühungsbeispielen in den beiliegenden Zeichnungen dargestellt und nachfolgend be schrieben.The invention is in several exemplary embodiments in the shown accompanying drawings and below be wrote.

Fig. 8 ein als Winkel mit einem Innengewinde und einem Aussengewinde ausgebildeter Fitting teils im Schnitt und Fig. 8 a fitting designed as an angle with an internal thread and an external thread, partly in section and
Fig. 9 eine Seitenansicht von Fig. 8. Fig. 9 is a side view of Fig. 8.
Die Fig. 1 bis 3 zeigen einen als Reduziermuffe 2 ausgebildeten Fitting 1, welcher zwei Innengewinde 3 a und 3 b mit unterschiedlichem Durchmesser aufweist. Die Aussen kontur der geraden Verschraubung ist achteckig ausgebildet, wobei ein grösserer Achtkant 4 a im Bereich des grösseren Innengewindes 3 a und ein kleiner Achtkant 4 b im Bereich des kleineren Innengewindes 3 b angeordnet ist. Der Uebergang 5 zwischen den beiden Achtkanten 4 a, 4 b ist kegelförmig aus gebildet. Figs. 1 to 3 show a reducer configured as 2 fitting 1, which has two inner thread 3 a and 3 b having different diameters has. The outer contour of the straight screw connection is octagonal, with a larger octagon 4 a in the area of the larger internal thread 3 a and a small octagon 4 b in the area of the smaller internal thread 3 b . The transition 5 between the two octagons 4 a , 4 b is conical.
Die Fig. 4 und 5 zeigen ein als T-Stück 10 mit drei gleichen Innengewinden 3 ausgebildeten Fitting 1, deren Aussenkontur im Bereich der Innengewinde 3 als Achtkant 4 ausgebildet ist. Die zwischen den Achtkanten befindliche Partie 11 der Aussenkontur ist im Querschnitt rund aus gebildet, wobei deren Aussendurchmesser dem Eckmass des Achtkantes 4 entspricht. FIGS. 4 and 5 show a fitting constructed as a T-piece 10 with three identical internal threads 3 1 whose outer contour is formed in the region of the inner thread 3 as an octagonal 4. The section 11 is located between the eight edges of the outer contour is formed in cross-section from about where the outside diameter corresponds to the width across corners of the octagon. 4
Fig. 6 und 7 zeigen einen als Winkel 20 mit zwei gleichen Innengewinden 3 ausgebildeten Fitting 1, wobei dei Aussen kontur ebenfalls in dem Bereich der Innengewinde 3 einen Achtkant 4 aufweist. Der bogenförmige Teil 21 ist im Quer schnitt rund ausgebildet, wobei der Aussendruchmesser dem Eckmass des Achtkantes entspricht. FIGS. 6 and 7 show a as the angle 20 formed with two equal internal threads 3 fitting 1, wherein dei having outer contour also in the region of the inner thread 3 of an octagon. 4 The arcuate part 21 is round in cross section, the outer diameter corresponding to the corner dimension of the octagon.
Die Fig. 8 und 9 zeigen ebenfalls einen Winkel 20, wobei an einem Ende ein Innengewinde 3 und am anderen Ende ein Aussengewinde 6 angeordnet ist. Die Aussenkontur ist im Bereich des Innengewindes mit einem Achtkant 4 versehen, wobei der bogenförmige Teil 21 wie bei Fig. 6 im Quer schnitt rund ausgebildet ist. FIGS. 8 and 9 also show an angle 20, which is disposed at one end an internal thread 3 and at the other end an external thread 6. The outer contour is provided in the area of the internal thread with an octagon 4 , the arcuate part 21 being round in cross section as in FIG. 6.
Selbstverständlich können die T-Stücke und Winkel auch mit im Durchmesser unterschiedlichen Innen- und/oder Aussen gewinden versehen sein, wobei jeweils mindestens im Be reich der Innengewinde die Aussenkontur als Mehrkant, vorzugsweise als Achtkant, ausgebildet ist.Of course, the T-pieces and angles can also be used different in diameter inside and / or outside be provided with threads, each at least in the loading if the internal thread has the outer contour as a polygon, is preferably designed as an octagon.
Der Achtkant ist dabei jeweils so angeordnet, dass zwei gegenüberliegende Ecken 7 in der Formtrennebene der Giess form zu liegen kommen (siehe Fig. 2, 3 und 5). Dies er ermöglicht ein einwandfreies Entformen der Gussteile und die Schlüsselflächen können zueinander parallel ausgebildet werden, wodurch eine mechanische Bearbeitung der Flächen entfällt.The octagon is arranged such that two opposite corners 7 come to lie in the mold parting plane of the casting mold (see FIGS. 2, 3 and 5). This enables the cast parts to be removed from the mold properly and the key surfaces can be formed parallel to one another, thereby eliminating mechanical machining of the surfaces.
Vorzugsweise werden die Fittings aus Temperguss hergestellt und anschliessend verzinkt.The fittings are preferably made from malleable cast iron and then galvanized.
