   Rohrbruch-Selbstschlussventil. 



   Das in den Fig. 1 im Längsschnitt und 2 im Querschnitt dargestellte Ventil bezweckt die   selbsttätige   Absperrung einer Druckleitung gegen die Druckquelle, zum Beispiel einer   Dampfrohrleitung gegen   einen Dampfkessel, im Augenblicke des Bruches der Dampfleitung, der Explosion eines angeschlossenen Dampfkessels oder eines ähnlichen Unfalles, selbst wenn die Bruchöffnung im Verhältnis zum Rohrquerschnitte am Selbstschlussventile nur gering ist. Das eigentliche Rohrbruchventil befindet sich in der unteren Kammer eines gewöhnlichen Durchgangsventilgehäuses a, in dessen oberer Kammer ein gewöhnliches Handabsperrventil angeordnet ist. 



     - Zu dem Rohrbruchventile gehören   ein Ventilkegel b, eine Spindel c und ein Gehäusedeckel d. Der Ventilkegel b hat eine obere Kegeldichtungsfläche e und eine untere Kegeldichtungsfläche f. sowie einen teilweise ausgesparten Führungscylinder g. Der Ventilkegel   li

   Austrian PATENT LETTERING? 11140. JOHANNEHRHARTOTTOKARRICHTERINKIEL.



   Pipe rupture self-closing valve.



   The valve shown in Fig. 1 in longitudinal section and 2 in cross section is intended to automatically shut off a pressure line against the pressure source, for example a steam pipe against a steam boiler, at the moment of the break in the steam pipe, the explosion of a connected steam boiler or a similar accident if the fracture opening is only small in relation to the pipe cross-section on the self-closing valve. The actual pipe rupture valve is located in the lower chamber of an ordinary straight-way valve housing a, in the upper chamber of which an ordinary manual stop valve is arranged.



     - The pipe burst valve includes a valve cone b, a spindle c and a housing cover d. The valve cone b has an upper cone sealing surface e and a lower cone sealing surface f. and a partially recessed guide cylinder g. The valve cone left
 EMI1.1
   a valve seat on the inner end of the spindle c. The spindle c, which is pierced in its longitudinal direction, allows the air to enter the valve cone b through the air duct h. The spindle can be moved up and down with the hand lever i; In this way, the mobility of the valve cone can be checked during operation and the valve can be closed instantaneously from near or far by means of a handle. The spindle leaves
