Description
Ausbildung der inneren Umkehrenden von Rohrtafeln, insbesondere für den Kesselbau.Formation of the inner turnaround of pipe panels, especially for boiler construction.
Es ist bei Rohrtafeln mit dicht aneinanderliegenden Rohren bekannt als Umkehrenden der innersten Rohre entweder besonders geformte Anschweisselemente zu verwenden, die in der Ebene der Rohrtafel liegen, oder, falls höhere Innen'rück zu beherrschen sind, die innersten Rohre aus der Rohrtafelebene nach der Feuerraumseite herauszubiegen und eine Schleife zu bilden.It is known in the case of pipe panels with pipes lying close together as the reversal of the innermost tubes, either specially shaped weld-on elements to be used that lie in the plane of the pipe sheet, or, if higher, inside back The innermost tubes from the tube sheet level to the combustion chamber side must be mastered to bend out and form a loop.
Die Schleife hat zwar gegenüber den Anschweisselementen den Vorteil geringerer Materialanhäufung, auch fallen die beiden Anschweissnähte fort, aber sie ist relativ langund daher einer unerwünscht hohen Wärmebelastung ausgesetzt.The loop has the advantage over the weld-on elements Less material accumulation, the two weld seams are also omitted, but it is relatively long and therefore exposed to an undesirably high thermal load.
Gemäss der Neuerung lässt sich dieser Nachteil weitgehend beheben, wenn die Umkehrschleife der innersten Rohre unter die aus der Rohrebene herausgebogene Umkehrung der ihnen benachbarten Rohre gelegt wird.According to the innovation, this disadvantage can largely be remedied, when the reverse loop of the innermost pipes is below the one bent out of the pipe plane Reversal of the pipes adjacent to them is placed.
Auf diese Weise tritt nur ein relativ kurzes Stück des Rohrstranges aus der Rohrtafelebene heraus, das nicht in Gefahr gerät überhitzt zu werden. Es ist auch möglich, die beiden innersten und die danebenliegenden Rohre je um den halben Rohrdurchmesser nach beiden Seiten aus der Tafelebene herauszubiegeno In diesem Falle ist in der hinter der Rohrtafel liegenden Wand eine Aussparung vorzusehen, wobei die Rohrtafel im übrigen an dieser Wand glatt anliegt.In this way, only a relatively short section of the pipe string occurs from the pipe sheet level, which does not run the risk of overheating. It is also possible, the two innermost ones and the ones next to them Pipes to be bent out of the sheet plane by half the pipe diameter on both sides In this case, a recess must be provided in the wall behind the pipe panel, wherein the pipe sheet is in the rest of the smooth contact with this wall.
In der Zeichnung ist die Neuerung in der Draufsicht und in Seitenansicht auf eine Rohrtafel dargestellt.In the drawing, the innovation is in the plan view and in side view shown on a pipe board.
Hierin zeigt Fig. 1 und 2 die bisherige Konstruktion
Gemäss, Fig. 1 bilden die beiden innersten Rohre 6 in bekannter Weise an der Umkehrung der Tafel eine aus der Ebene der Rohrtafel herausgeführte Schleife 7, die gemäss Fig. 2 über den darunterliegenden Rohren 8 liegt.According to FIG. 1, the two innermost tubes 6 form in a known manner at the inversion of the board a loop leading out of the plane of the pipe board 7, which, according to FIG. 2, lies above the tubes 8 below.
Fig. 3 zeigt die neuerungsgemässe Ausführung, wobei die innersten Rohre 6 eine kurze Rundschleife 7' bilden, die unter der aus der Tafelebensherausgebogenen Umkehrung der benachbarten Rohre 9 liegt.Fig. 3 shows the innovation according to the embodiment, the innermost Tubes 6 form a short round loop 7 ', which is below the one bent out of the table Reversal of the adjacent tubes 9 is located.
Die Rohre 8 liegen wieder völlig in der Rohrtafelebene. Vergleiche
