Description

Es sind bereits Sicherheitsventile bekannt, deren Spindel von der Belastung auf Zug beansprucht wird, wob«, die Größe der Be- - lastung einstellbar ist und durch Federkraft erfolgt. Bei Baautzung derartiger Ventile für sehr hohe Drücke, z. B. r ooo at, erhält die Feder im Verhältnis zum Ventil sehr große, unbequeme Abmessungen, deren Verminderung sich die Erfindung zur AufgabeThere are already safety valves known, the spindle of the load on train is stressed, wob «, the size of the load is adjustable and by spring force he follows. When using such valves for very high pressures, e.g. B. r ooo at the spring in relation to the valve very large, uncomfortable dimensions, their reduction the invention is the task

ίο gestellt hat. Die Lösung besteht darin, daß die Ventilspindel selbst elastisch ausgebildet und dadurch die Feder gespart wird. Die Spindel wird dabei entsprechend bemessen und durch eine Anzugsmutter so weit unter Spannung gesetzt, daß sie dem unter dem Ventilteller wirkenden Arbeitsdruck das Gleichgewicht hält.ίο has asked. The solution is that the valve spindle itself is designed to be elastic and the spring is saved as a result. the Spindle is dimensioned accordingly and by a tightening nut so far below Tension is set so that it keeps the working pressure acting under the valve disc in equilibrium.

In der Abbildung ist ein Ausführungsbeispiel dargestellt, a. ist das Ventilgehäuse.In the figure, an embodiment is shown, a. is the valve body.

ao Die Bohrung & steht durch Kanäle mit dem Druckraum des zu sichernden Behälters in Verbindung. Die Ventilspindel trägt oben den Ventilkegel d und besteht im übrigen aus dem Dehnungsteil. 5, einem Dichtungsfcolben / undao The bore & is connected to the pressure chamber of the container to be secured through channels. The valve spindle carries the valve cone d at the top and also consists of the expansion part. 5, a sealing piston / and

£5 einem Gewindeteil g. Dieser Gewindeteil mit der Anzugmutter h liegen außerhalb des Gehäuses, damit die Einstellung der Belastung jederzeit erfolgen kann. Zu diesem Zweck ist der Gehäuseraum b mit einer der Mutter h vorgelagerten Stopfbüchse abgedichtet. Um beim Anziehen der Mutter h ein Verwinden des Dehnungsteiles e der Spindel auszuschließen, ist ein Sicherungsstück i vorgesehen, welches mit Nasen oder Keilen einerseits in die Ventilspindel, anderseits in die Gehäusewand eingreift. £ 5 a threaded part g. This threaded part with the tightening nut h lie outside the housing so that the load can be adjusted at any time. For this purpose, the housing space b is sealed with a stuffing box upstream of the nut h. In order to prevent the expansion part e of the spindle from twisting when the nut h is tightened, a locking piece i is provided which engages with lugs or wedges on the one hand in the valve spindle and on the other hand in the housing wall.

Die Einstellung der Ventilbelastung ist durch die Mutter h genau regelbar. Überschreitet der Druck im Innern des Gehäuses die eingestellte Größe, so wächst infolge der zunehmenden Ventilbelastung die Spindellänge, und das Ventil öffnet sich.The setting of the valve load can be precisely regulated by the nut h. If the pressure inside the housing exceeds the set value, the spindle length increases as a result of the increasing valve load, and the valve opens.

Claims (1)

Patentanspruch:Claim: Sicherheitsventil, dessen Ventilspindel von der einstellbaren Belastung auf Zug beansprucht wird, dadurch gekennzeichnet, daß die Ventilspindel selbst elastisch ist, so daß sie die Belastungsfeder ersetzt.Safety valve, the valve spindle of which is subject to tension from the adjustable load is claimed, characterized in that the valve spindle itself is elastic, so that it replaces the loading spring.
