Description

Blockiereinrichtung von direktbelasteten Sicherheitsventilen Direktbelastete Sicherheitsventile, z. B. federbelastete Sicherheitsventile, müssen eine Blockiereinrichtung haben, damit im Schadensfall dieses Sicherheitsventil blockiert werden kann oder bei Druckproben der Anlage mit erhöhtem Probedruck der normale Einstelldruck des Sicherheitsventils nicht erhöht zu werden braucht durch Spannung der Feder oder Erhöhung der Gewichte.Blocking device of direct loaded safety valves Direct loaded Safety valves, e.g. B. spring-loaded safety valves must have a blocking device so that this safety valve can be blocked in the event of damage or in the case of pressure tests of the system with increased test pressure, the normal set pressure of the Safety valve does not need to be increased by tensioning the spring or Increase in weights.

Es ist, wie in Abb. 1 dargestellt, bekannt, diese Blockierung dadurch zu ermöglichen, daß in die ohnehin vorhandene Kappe des Sicherheitsventils ein Gewinde eingeschnitten wird in Achsrichtung der Ventilspindel, wobei dieses Gewinde einmal durch einen Stopfen verschlossen werden kann und zum anderen mit einem an diesem Stopfen durch eine Kette anhängenden Blockierknebel festgesetzt werden kann. Weiterhin sind zusätzliche Blockieraufsätze bekannt, die unabhängig von der normalen Ventilkappe geliefert werden.As shown in Fig. 1, it is known to cause this blocking to enable a thread in the already existing cap of the safety valve cut is made in the axial direction of the valve spindle, this thread once can be closed by a stopper and on the other hand with one on this The stopper can be fixed by means of a locking toggle attached to a chain. Farther additional blocking attachments are known that are independent of the normal valve cap to be delivered.

Die Erfindung befaßt sich mit einer Blockierschraube, die in die normale vorhandene Kappe in an sich bekannter Weise eingeschraubt werden kann, wobei eine wesentliche Verbilligung erzielt wird.The invention relates to a locking screw, which in the normal existing cap can be screwed in a known manner, with a substantial cheaper is achieved.

Die Erfindung besteht darin, für die Blockiereinrichtung eine Kopfschraube zu verwenden, die einerseits einen kurzen und andererseits einen langen Gewindebolzen trägt. Nach einem weiteren Erfindungsmerkmal trägt diese Kopfschraube ein vorzüglich in einer auffallenden Farbe gekennzeichnetes Schild, das bei eingeschraubtem kurzem Gewindeende die Aufschrift trägt, daß das Ventil nicht blockiert ist, und bei eingeschraubtem langen Gewindeende und damit blockiertem Ventil die Aufschrift trägt, daß das Ventil blockiert ist. Abb. 2 zeigt in einer Skizze ein Ausführungsbeispiel der Erfindung. Das Warnschild a ist dabei fest mit der Kopfschraube b verbunden.The invention consists in a head screw for the blocking device to use, on the one hand a short and on the other hand a long threaded bolt wearing. According to a further feature of the invention, this head screw has an excellent The shield is marked in a striking color, and when it is screwed in, the short The end of the thread is labeled that the valve is not blocked, and when it is screwed in long thread end and thus blocked valve is labeled that the valve is blocked. Fig. 2 shows a sketch of an embodiment of the invention. The warning sign a is firmly connected to the head screw b.
