Description
Die Erfindung betrifft eine Verbindung von zwei oder mehreren Rohren zu einem gemeinsamen Rohrquerschnitt, die gegenüber den bekannten Rohrverbindungen durch gemeinsame längsverlaufende Stege im Übergangsstück hochdrucksicher gestaltet ist.The invention relates to a connection of two or more pipes to a common one Pipe cross-section, which compared to the known pipe connections by common longitudinal webs in the transition piece is designed high pressure safe.
Durch die Erfindung wird es besonders für hohe Betriebsspannungen möglich, Einzelrohre vor ihrer Verbindung mit den zugehörigen Kesselkörpern o. dgl. zu einem Querschnitt miteinander zu vereinigen, wodurch die Zahl der Rohrlöcher in den Kesseltrommeln o. dgl. geringer wird und die Kesseltrommeln mit kleinem Durchmesser und dünneren Wandungen ausgeführt werden können. Alle dargestellten Rohrverbindungen führen als kennzeichnendes Merkmal die gemeinsamen längsverlaufenden Stege/ im Übergangsstück, die im Berührungspunkt g derThe invention makes it possible, especially for high operating voltages, to unite individual pipes before they are connected to the associated boiler bodies or the like to form a cross section, whereby the number of pipe holes in the boiler drums or the like is reduced and the boiler drums have a small diameter and thinner walls can be carried out. All the pipe connections shown lead as a characteristic feature the common longitudinal webs / in the transition piece, which in the contact point g of
ao Einzelrohre beginnen und in e enden. Die schraffierten Stegflächen f bzw. die Querschnittsabb. 3, 4, 5, 6, 8, 10, 11, 12 und 14 aus den Schnitten 1-1, 2-2 usw. bis 10-10 zeigen, wie die Einzelrohre allmählich in die einzelnen Kreisausschnittquerschnitte übergehen und das Einzelrohr b im Punkte g den gemeinsamen Steg/ erst verläßt, wenn der Kreisquerschnitt voll erreicht ist, während andererseits die gemeinsamen Stege erst dort aufhören, wo der gemeinsame Querschnitt kreisförmige Form hat.ao single pipes start and end in e. The hatched web areas f or the cross-sectional fig. 3, 4, 5, 6, 8, 10, 11, 12 and 14 from sections 1-1, 2-2, etc. to 10-10 show how the individual tubes gradually merge into the individual circular section cross-sections and the individual tube b at point g leaves the common web / only when the circular cross-section is fully reached, while on the other hand the common webs only stop where the common cross-section has a circular shape.
Abb. ι zeigt eine Verbindung von drei Rohren, Abb. 13 und 14 eine solche von vier Rohren, während Abb. 7 und 9 die stufenweise Verbindung von 4:2:1 Rohr darstellt, wobei je zwei Einzelrohre b zu einem Astrohrstück b1 und zwei Astrohrstücke b1 zu einem gemeinsamen Stammrohr stück α vereinigt werden. Die längsverlaufenden Rohrstege / bilden mit dem Übergangsstück ein gemeinsames Ganzes, wodurch gegenüber dem Bekannten ein hochdrucksicheres Rohrelement erreicht wird, auch wird durch den Zusammenschluß der Einzelquerschnitte in e eine gleichmäßige Verteilung des strömenden Mittels auf die Einzelrohre erreicht.Fig. Ι shows a connection of three tubes, Fig. 13 and 14 one of four tubes, while Fig. 7 and 9 shows the stepwise connection of 4: 2: 1 tube, with two individual tubes b to a branch tube piece b 1 and two branch pieces b 1 are combined into a common stem pipe piece α . The longitudinal pipe webs / form a common whole with the transition piece, whereby a high-pressure-safe pipe element is achieved compared to the familiar, and the merging of the individual cross-sections in e achieves a uniform distribution of the flowing medium on the individual pipes.
