Description

Die Erfindung betrifft eine Einrichtung zur Absicherung druckbelasteter Anlagenteile gegen unzulässigen Überdruck.The invention relates to a device for protecting pressurized system parts against impermissible ones Overpressure.

Druckbelastete Anlagenteile sind durch den Einbau von Sicherheitsventilen oder Berstscheiben gegen unzulässigen Überdruck gesichert So ist auf der Seite 194 des Buches »Handbook of Industrial Pipework Engineering« Verlag McGraw-Hill, London, 1973 eine Absicherung gegen Überdruck beschrieben, die außer dem Sicherheitsventil zusätzlich eine Berstscheibe aufweist Zwar soll bei NichtÖffner des Sicherheitsventils eine auf einen höheren Druck ausgelegte Berstscheibe die Anlage vor Schaden schützen und die Druckentlastung sicherstellen. Demgegenüber geht die Anmeldung ^ on einem anderen Problem aus. Im Anforderungsfall ist es nämlich nicht auszuschließen, daß das Venti! nach erfolgter D-uckabsenkung nicht mehr schließt und fälschlich offen stehen bleibt Das ^bedeutet unkontrollierten und unerwünschten Druck- und Inventarverlust der abgesicherten Komponente oder des Systems.Pressure-loaded parts of the system are countered by installing safety valves or rupture discs inadmissible overpressure secured Engineering «McGraw-Hill Publishing House, London, 1973 described a protection against overpressure that except the safety valve also has a rupture disc a rupture disc designed for a higher pressure protect the system from damage and the Ensure pressure relief. In contrast, the registration ^ starts from a different problem. in the If required, it cannot be ruled out that the Venti! not after the pressure has been reduced more closes and wrongly remains open The ^ means uncontrolled and undesirable pressure and loss of inventory of the protected component or system.

Die Erfindung stellt sich daher die Aufgabe eine Absperrmöglichkeit zu finden, die ein weiteres Ausströmen von Medium aus dem gesicherten Anlagenteil nach erfolgter Druckabsenkung und bei nicht schließendem Sicherheitsventil verhindert Dabei muß sichergestellt sein, daß beim funktionsgemäßen Ansprechen des Sicherheitsventils eine Blockierung des Abblaseweges ausgeschlossen istThe invention therefore sets itself the task of finding a shut-off option that allows further outflow of medium from the secured part of the system after the pressure has been reduced and when it does not close Safety valve prevented It must be ensured that when the Safety valve a blockage of the blow-off path is excluded

Gelöst wird die Aufgabe erfindungsgemäß dadurch,The object is achieved according to the invention by

-, daß eine Abblaseleitung des Sicherheitsventil;! eine Absperrarmatur aufweist und daß die Absperrarmatur in bekannter V/eise von einer Bypaßleitung umfahren ist die mit einer Berstscheibe verschlossen ist.- that a blow-off line of the safety valve ;! one Has shut-off valve and that bypassing the shut-off valve in a known V / ice of a bypass line is closed with a rupture disc.

Diese Anordnung gestattet eine zuverlässige Absper-This arrangement allows a reliable shut-off

If the shut-off valve closes incorrectly the rupture disc responds in the event of overpressure and relieves the pressure of the corresponding part of the system
