KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Vorliegende Erfindung betrifft ein Rohrbruchventil , welches für gewöhnlich offen gehalten wird, jedoch beim Bruch eines Rohres durch den im Rohre entstehenden Druckunterschied selbsttätig geschlossen wird. In der beiliegenden Zeichnung ist das Ventil in Fig. ι im Längsschnitt in Bereitschaftsstellung dargestellt. Fig. 2 stellt eine Oberansicht und Schnitt vom Regulierstift dar.The present invention relates to a burst pipe valve which is usually open is held, but is automatically closed when a pipe breaks due to the pressure difference in the pipe. In the accompanying drawing, the valve in Fig. Ι is in the standby position in longitudinal section shown. Fig. 2 shows a top view and section of the regulating pin. ίο Der Doppelkegel a, welcher aus einem Stück hergestellt ist, wird durch den Stempel c, welcher am unteren Ende schneidenförmig gestaltet ist und in eine eingedrehte Rille b des Verbindungsstückes d beider Kegel eingreift, in seiner Bereitschaftslage gehalten, so daß bei normalem Betrieb, bei welchem der Druck in der ganzen Leitung derselbe bleibt, der Dampf ungehindert durch den vollen Querschnitt des Ventiles hindurchtreten kann.ίο The double cone a, which is made from one piece, is held in its ready position by the punch c, which is designed like a cutting edge at the lower end and engages in a turned groove b of the connecting piece d of both cones, so that during normal operation, at which the pressure in the whole line remains the same, the steam can pass unhindered through the full cross-section of the valve. Das Ventil ist oben mit Hebel/ und einem Gewicht ausgerüstet, welches den zum Festhalten des Kegels nötigen Druck ausübt und auf dem Hebel verschoben werden kann, wodurch sich der Druck regeln läßt.The valve is equipped at the top with a lever / and a weight, which the to hold of the cone exerts the necessary pressure and can be moved on the lever, whereby the pressure can be regulated. Findet während des Betriebes ein Rohrbruch statt, so findet eine größere Zug- bezw. Druckwirkung des Dampfes auf das Ventil statt. Infolgedessen wird sich der Kegel bis zu einer den Ventilschluß herbeiführenden Endlage verschieben entgegen der Belastung des auf die kegelförmige Fläche b wirkenden, durch den Gewichtshebel e f angepreßten Stempels c, der angehoben wird und auf den Umfang des Verbindungsstückes der Ventile zu liegen kommt-If a pipe rupture occurs during operation, there will be a greater pull or pull. Pressure effect of the steam on the valve takes place. As a result, the cone will move up to an end position causing the valve closure against the load of the stamp c, which acts on the conical surface b and is pressed by the weight lever ef , which is raised and comes to rest on the circumference of the connecting piece of the valves. Soll nun nach beendigter Reparatur der Rohrleitung der Betrieb wieder aufgenommen werden, so löst man den Verbindungsstift h am oberen Ende des Stempels und dreht mittels eines Schlüssels den Sechskant um i8o°, wodurch mittels des Daumens i der Kegel wieder in seine Bereitschaftslage gebracht wird, worauf man .dann den Verbindungsstift h wieder befestigt. Das Ventil ist hiernach wieder betriebsfähig hergestellt.If operation is to be resumed after the repair of the pipeline has been completed, the connecting pin h at the upper end of the stamp is loosened and the hexagon is turned by 180 ° using a key, whereby the cone is brought back into its ready position using the thumb i, whereupon man .then fastened the connecting pin h again. The valve is then restored to working order. Pate nt-A ν SPRU c 11:Pate nt-A ν SPRU c 11: Nach zwei Seiten hin selbsttätig schließendes Rohrbruchventil mit einem Doppelkegel als Abschlußkörper, dessen Achse in der Durchflußrichtung liegt, dadurch gekennzeichnet, daß der Doppelventilkörper (d) durch einen gewichtsbelasteten Stempel (c), der mit seinem unteren schneidenförmigen Ende in einer doppelkegelförmigen Nut des Ventilkörpers ruht, in seiner Mittellage gehalten wird, bis er bei eintretendem Rohrbruche durch den vermehrten Zug oder Druck des nach der Rohrbruchstelle strömenden Leitungsstoffes in die entsprechende Schlußstellung geschleudert wird.Automatically closing pipe rupture valve on two sides with a double cone as the closing body, the axis of which lies in the direction of flow, characterized in that the double valve body (d) is supported by a weight-loaded plunger (c) which rests with its lower blade-shaped end in a double-conical groove of the valve body , is held in its central position until it is thrown into the corresponding final position when the pipe ruptures due to the increased tension or pressure of the line material flowing towards the pipe rupture point.
