Description
<Desc/Clms Page number 1>
Rohrbruchventil mit durch das Treibmittel belastetem Selbstschlusskörper,
Durch die eigentümliche Konstruktion und Wirkungsweise des Rohrbruchventiles nach Patent Nr. sol853, durch welche eine stetige Dampfbelastung erzielt wird, ist diese Einrichtung weniger als andere der Wirkung des vom Dampf mitgeführten Wassers ausgesetzt.
Um den Selbstschlusskörper jedoch der Wirkung dieser Wasserteilchen gänzlich zu entziehen, erhält er, wie die Zeichnung zeigt, einen zylindrischen Rand r, welcher in einen rohrförmigen Vorsprung a des Ventilgehäuses mit entsprechendem Zwischenraum hineinragt (also nicht wie ein Kolben abdichtet), so dass das vom Dampf mitgeführte, mit grosser Geschwindigkeit anlangeude Wasser nur höchstens den zylindrischen Rand, nicht aber die kegelförmige Fläche des Selbstschlusskörpers a treffen kann.
Um zu verhindern, dass der vorüberströmende Dampf einen Druckabfall in dem Raum unter dem Selbstscblusskörper verursache, wird dessen zylindrischer Rand r durchbohrt, wie bei p ersichtlich.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Pipe rupture valve with self-closing body loaded by the propellant,
Due to the peculiar design and mode of operation of the pipe rupture valve according to patent no. Sol853, through which a constant steam load is achieved, this device is less exposed than others to the action of the water carried by the steam.
However, in order to completely remove the action of these water particles from the self-closing body, it receives, as the drawing shows, a cylindrical edge r, which protrudes into a tubular projection a of the valve housing with a corresponding gap (i.e. not sealing like a piston), so that the from Steam entrained at high speed water can only hit the cylindrical edge, but not the conical surface of the self-closing body a.
In order to prevent the steam flowing past causing a pressure drop in the space under the self-closing body, its cylindrical edge r is pierced, as can be seen at p.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
