■ Wenn in einer Dampfleitung eine Richtungsänderung des Dampfes eintreten mufs, wie dies beispielsweise bei der Leitung des Abdampfes zwischen Dampfmaschinencylinder und dem Condensator vorkommt, wenn der Condensator eingeschaltet und die Auspuffleitung ins Freie versperrt werden soll, mufs eine Umstellvorrichtung vorhanden sein. Bei solcher Vorrichtung ist es aber von nachtheiligem Einflufs, wenn der Dampf, beispielsweise in seiner Stromrichtung nach dem Condensator, beim Passiren der Umstellvorrichtung seine Richtung verändern mufs, wodurch durch Reibung und oft auch durch Einengung ein Rückdruck erzeugt wird, der den Gang der Maschine ungünstig beeinflufst.■ When the direction of the steam has to change in a steam line, such as this for example in the conduction of the exhaust steam between the steam engine cylinder and the Condensator occurs when the condenser is switched on and the exhaust pipe ins If free is to be blocked, a changeover device must be available. With such However, it is detrimental to the device if the steam, for example in its current direction to the condenser, its when passing the changeover device The direction has to change, as a result of which a back pressure is generated through friction and often also through narrowing, which increases the speed of the Machine adversely affected.

Durch die nachfolgend beschriebene Anordnung der Umstellvorrichtung werden solche nachtheiligen Einflüsse gänzlich vermieden, indem dem Dampfe, beispielsweise beim Zuströmen zum Condensator, der freie Querschnitt des Rohres ohne jede Aenderung seiner Zuströmungsrichtung oder Einengung geboten wird.Due to the arrangement of the changeover device described below, such detrimental influences are completely avoided by adding the steam, for example when flowing in to the condenser, the free cross-section of the pipe without any change in it Direction of flow or constriction is offered.

Die Ventilklappe ist in Fig. 1 und 2 in rechtwinklig zu .einander stehenden lothrechten Schnitten und in Fig. 3 im waagrechten Schnitt in Höhe der Ventilklappen-Drehachse dargestellt.The valve flap is perpendicular to each other in FIGS. 1 and 2 Sections and in Fig. 3 in a horizontal section at the level of the valve flap axis of rotation shown.

Angenommen, es sei der waagrechte Theil der Leitung derjenige, in welchem der Dampf in der Pfeilrichtung von dem Dampfmaschinencylinder zum Condensator strömt, wenn die Ventilklappe α in waagrechter Richtung steht, während der Krümmung die Ableitung des Dampfes ins Freie bildet, wenn die Ventilklappe, wie punktirt angegeben, die waagrechte Leitung -sperrt. Die Klappe α ist bei h aufserhalb des Leitungsquerschnittes drehbar aufgehängt.Assume that the horizontal part of the line is the one in which the steam flows in the direction of the arrow from the steam engine cylinder to the condenser when the valve flap α is in the horizontal direction, while the bend forms the discharge of the steam to the outside when the valve flap, as indicated dotted, the horizontal line -blocks. The flap α is rotatably suspended at h outside the line cross-section.

Die Sitze für die an jeder Seite mit Dichtflächen versehene Ventilklappe α werden gebildet in der waagrechten Leitung durch das Einsatzstück g \ in dem Krümmung durch das Einsatzstück g. Zur Umstellung der Ventilklappe ist die Wand des Krümmlings durchbrochen und diese Durchbrechung e zur Aufnahme der verschiebbaren Hülse c eingerichtet. Diese Hülse wird durch eine Feder K, die in einer Nuth der Durchbrechungswand gleitet, gegen Drehung gesichert, während die Hülse in ihren ausgeschobenen und eingeschobenen Stellungen durch Schraube/ festgestellt werden kann. Die Verschiebung der Hülse wird durch ihre Endflantschen d d begrenzt. The seats for the valve flap α , which is provided with sealing surfaces on each side, are formed in the horizontal line by the insert piece g in the bend through the insert piece g. To move the valve flap, the wall of the curvature is perforated and this opening e is set up to accommodate the displaceable sleeve c . This sleeve is secured against rotation by a spring K, which slides in a groove in the opening wall, while the sleeve can be fixed in its pushed-out and pushed-in positions by screw /. The displacement of the sleeve is limited by its end flanges dd.

Die Hülse dient in ihrem oberen Theil als Mutter für die mit Handrad ausgestattete und geeignet geführte Ventilspindel b. The upper part of the sleeve serves as a nut for the valve spindle b equipped with a handwheel and guided in a suitable manner.

Letztere ist mit der Ventilklappe durch ein Gelenkstück η so verbunden, dafs eine Drehung der Spindel b in jeder Stellung der Klappe α stattfinden kann.The latter is connected to the valve flap by an articulated piece η in such a way that the spindle b can rotate in any position of the flap α .

Um die Klappe α aus der waagrechten in die niedergeklappte Stellung überzuführen, .wird nach Lösung der Schraube f die Hülse liiedergeschoben, bis sie auf dem oberen Flantsch d aufliegt, worauf sie durch Schraube/ in dieser Lage festgestellt wird; es legt als-To move the flap α from the horizontal to the folded-down position, after loosening the screw f, the sleeve is pushed until it rests on the upper flange d , whereupon it is determined by the screw / in this position; it lays as-

dann die mit heruntergehende Spindel b durch Gelenkstück η die Klappe gegen den Sitz g-1, und eine geringe Drehung des Handrades in der einen Richtung genügt, um die Klappe auf g1 abzudichten. Es ist dann der Weg zum Condensator abgesperrt. Um diesen Weg zu öffnen, wird Schraube f wieder gelöst, die Hülse in die Höhe geschoben, in dieser Stellung durch Schraube f festgestellt und die mitgenommene Klappe a, welche sich mit ihrer anderen Seite gegen g gelegt hat, durch Drehung des Handrades in anderer Richtung fest angezogen.Then the downward spindle b through the joint piece η the flap against the seat g- 1 , and a slight turn of the handwheel in one direction is sufficient to seal the flap on g 1. The way to the condenser is then blocked. To open this way, screw f is loosened again, the sleeve is pushed up, fixed in this position by screw f and the flap a, which has its other side placed against g , by turning the handwheel in the other direction tightened firmly.

Der gerade Weg für den Abdampf zum Condensator ist dann frei und die Leitung ist in keiner Weise durch die Umstellvorrichtung beengt.The straight path for the exhaust steam to the condenser is then free and the line is open in no way restricted by the changeover device.

Es empfiehlt sich, die Lagerung der Klappe lose in dem Sinne auszuführen, dafs sich die Klappe fest gegen den Sitz g anziehen läfst,: It is advisable to mount the flap loosely in such a way that the flap can be tightened firmly against the seat g :
