In der Patentanmeldung Z 5092 XII/47 g ist ein selbsttätig wirkendes Schlauchbruchventil, insbesondere für Feuerlöschzwecke, mit einem stromlinienförmig gestalteten Ventilkegel beschrieben, dessen Schließbewegung durch einen Bremszylinder gebremst ist, der in einem zweiten Stromlinienkörper angeordnet ist.In the patent application Z 5092 XII / 47 g is an automatically acting hose rupture valve, in particular for fire extinguishing purposes, described with a streamlined valve cone, its Closing movement is braked by a brake cylinder, which is arranged in a second streamlined body is.
Das Schlauchbruchventil nach der genannten Patentanmeldung wirkt einwandfrei, solange die daran angeschlossene Schlauchleitung mit Wasser ge- ίο füllt ist. Beim Füllen der Schlauchleitung treten aber häufig so große Strömungsgeschwindigkeiten im Ventil auf. daß das Schlauchbruchventil die Wasserzufuhr absperrt, obwohl kein Schlauchbruch vorliegt.The hose rupture valve according to the patent application mentioned works properly as long as the the hose line connected to it is filled with water. When filling the hose line, however, step often so high flow velocities in the valve. that the hose rupture valve is the water supply shuts off although there is no hose break.
Die Erfindung betrifft eine zusätzliche Vorrichtung an dem Rohrbruchventil nach der genannten Patentanmeldung, welche das Schlauchbruchventil für die Zeit der Schlauchfüllung wirkungslos macht.The invention relates to an additional device on the pipe rupture valve according to the patent application mentioned, which makes the hose rupture valve ineffective while the hose is being filled.
Die Vorrichtung nach der Erfindung besteht in siner in die Wand des Bremszylinders eingebaute Sperrvorrichtung, welche die Bewegung der Kolbenstange so lange blockiert, bis die an das Schlauchbruchventil angeschlossene Schlauchleitung und der Bremszylinder vollständig gefüllt sind. In einer bevorzugten Ausführungsform besteht die Sperrvorrichtung aus einem in die Zylinderwand eingelassenen profilierten Gummiring, dessen innerer Durchmesser in entspanntem Zustand kleiner ist als der innere Durchmesser des Bremszylinder*.The device according to the invention consists in siner built into the wall of the brake cylinder Locking device that blocks the movement of the piston rod until it hits the hose rupture valve connected hose line and the brake cylinder are completely filled. In a preferred Embodiment, the locking device consists of a let into the cylinder wall profiled rubber ring, the inner diameter of which is smaller than the inner one in the relaxed state Brake cylinder diameter *.
In der Zeichnung ist ein Ausführungsbeispiel dieser zusätzlichen Vorrichtung nach der Erfindung dargestellt. In the drawing, an embodiment of this additional device according to the invention is shown.
Der Ventilkegel 2 sitzt auf der Kolbenstange 10, die an ihrem Ende den Kolben 9 in der Bremszylinderkammer 4 c trägt. Im rechten Lagerkörper 4 a des Schlauchbruchventils ist in der Wand des Bremszylinder*^ ein Gummiring 22 vorgesehen, der in der Zeichnung teilweise im Schnitt zu sehen ist. Dieser Gummiring ist längs seines inneren Umfang* mit einer Verstärkungsrippe versehen. Während das Wasser beim Füllen in die Schlauchleitung einströmt und in dieser noch kein ausreichender Gegendruck herrscht, ragt der Gummiring mit der Verstärkungsrippe in den Bremszylinderraum hinein und liegt vor dem Bremskolben 9, so daß die Bewegung des Ventilkegeis in der Schließrichtung gesperrt ist. Mit der Schlauchleitung füllt sich auch der Bremszylinder mit Wasser, das schließlieh den Gummiring so weit ausdehnt, daß die Verstärkungsrippe außerhalb des Laufweges des Bremskolbens liegt. Falls dann ein Bruch in der Schlauchleitung auftritt, kann sich der Kolben 9 ungehindert bewegen. Damit ist die normale Funktion des Ventils wiederhergestellt.The valve cone 2 sits on the piston rod 10, which at its end the piston 9 in the brake cylinder chamber 4c bears. In the right bearing body 4 a of the hose rupture valve is in the wall of the brake cylinder * ^ a rubber ring 22 is provided, which can be seen partially in section in the drawing. This The rubber ring is provided with a reinforcing rib along its inner circumference *. While that Water flows into the hose line during filling and there is not yet sufficient counter pressure in it prevails, the rubber ring with the reinforcing rib protrudes into the brake cylinder chamber and is present the brake piston 9, so that the movement of the valve cone is blocked in the closing direction. With the The hose line also fills the brake cylinder with water, which eventually expands the rubber ring so far that that the reinforcing rib lies outside the path of the brake piston. If so, then a break occurs in the hose line, the piston 9 can move freely. That’s the normal one Function of the valve restored.

Gummiring 22 an seinem Umfang eine Nut, welche die Formänderung des Gummiringes erleichtert. Die Bohrung 23, welche den Lagerkörper 4 α und das Ventilgehäuse 1 durchsetzt, dient der Entlüftung dieser Nut. Die beschriebene Vorrichtung sperrt und entsperrt den Bremskolben und damit das Ventil völlig selbsttätig in einer sehr einfachen und betriebssicheren Gestaltung.Rubber ring 22 has a groove on its circumference, which facilitates the change in shape of the rubber ring. The bore 23, which passes through the bearing body 4 α and the valve housing 1, is used to vent this groove. The device described locks and unlocks the brake piston and thus the valve completely automatically in a very simple and operationally reliable design.
