Description

Zur besseren Führung des Strömungsmittels bei geöffneten Schiebern werden Leitrohre verwandt, die am Ende des als Kreuz ausgebildeten Schieberplattenhalters befestigt sind. In geöffnetem Zustand des Schiebers sitzt das Leitrohr zwischen Schiebergehäuseeintritt und -austritt. Das Leitrohr hat den gleichen Durchmesser wie die Schiebergehäusebohrung und führt das Strömungsmittel verhältnismäßig reibungslos und ohne Wirbelbildung durch das Schiebergehäuse.Guide tubes are used for better guidance of the fluid when the gate valves are open. which are attached to the end of the slide plate holder, which is designed as a cross. When open The guide tube sits between the valve body inlet and outlet. The guide scope has the same diameter as the valve body bore and carries the fluid relatively smoothly and without vortex formation through the valve body.

Diese Leitrohre sind gewöhnlich mit zwei Schweißraupen am Ende des Schieberplattenhalters befestigt. Es hat sich aber gezeigt, daß die Leitrohre im Laufe des Betriebes sehr häufig abbrechen dadurch, daß die Schweißnähte abreißen. Sie liegen dann im unteren Schiebergehäuseteil, und die beabsichtigte Wirkung, das Strömungsmittel reibungslos und wirbelfrei durch das Schiebergehäuse zu führen, wird nicht mehr erreicht.These guide tubes usually have two weld beads at the end of the gate holder attached. It has been shown, however, that the guide tubes break off very frequently in the course of operation in that the welds tear off. They are then in the lower part of the valve body, and the intended one Effect, the fluid flows smoothly and vortex-free through the valve body lead is no longer achieved.

Die Ursache für das Abreißen liegt darin, daß das Stück des Leitrohres, das zwischen den beiden Schweißnähten sitzt, sich bei der Erwärmung und Abkühlung anders ausdehnt und zusammenzieht als das massive Schieberkreuz.The cause of the tearing is that the piece of guide tube that is between the two Welds, expands and contracts differently when heated and cooled the massive slide cross.

Dieser Nachteil bei der üblichen Schweißverbindung wird gemäß der Erfindung dadurch beseitigt, daß das Leitrohr zwischen den Schweißnähten in Längsrichtung geschlitzt ist. In der Zeichnung ist ein Schieber mit Leitrohr im teilweisen Schnitt dargestellt. Am unteren Ende des als Kreuz ausgebildeten Schieberplattenhalters 1 ist das Leitrohr 2 durch zwei Schweißnähte 3, die sich auf beiden Seiten des Schieberplattenhalterendes erstrecken, angeschweißt. Zwischen den Schweißnähten 3 weist das Leitrohr den Schlitz 4 auf, durch dessen Anordnung sich die Spannungen nicht mehr auf die Schweißnähte auswirken können.This disadvantage with the usual welded connection is eliminated according to the invention by that the guide tube is slit in the longitudinal direction between the welds. In the drawing is a slide with guide tube shown in partial section. At the lower end of the shaped as a cross Slide plate holder 1 is the guide tube 2 by two welds 3, which are on both Extending sides of the gate retainer end, welded on. Between the welds 3, the guide tube has the slot 4, due to the arrangement of which the stresses do not arise can have more effect on the welds.
