Description

Einrichtung zum Absperren eines Sicherheitsventils)das mit einer Abblaseleitung versehen 1st.Device for shutting off a safety valve) with a blow-off line is provided.

Die Erfindung betrifft eine Einrichtung zum Absperren eines Sicherheitsventils das mit einer Abblaseleitung versehen ist.The invention relates to a device for shutting off a safety valve with a blow-off line is provided.

Druckbelastete Anlagenteile müssen aus Sicherheitsgründen gegen Überdruck gesichert sein. In der Regel erfolgt diese überdrucksicherung durch ein Sicherheitsventil. Im Anforderungsfall besteht eine bestimmte Wahrschelnlichk e i t_ dafür, "daß das Ventil nach Druckabsenkung nicht mehr schließt und fälschlich offen stehen bleibt. Das bedeutet unkontrollierten und unerwünschten Druck- und Inventarverlust der abgesicherten Komponente oder des Systems. Eine Absperrmöglichkeit, die die Funktion des Sicherheitsventils verhindertest unzulässig.System parts subject to pressure must be secured against overpressure for safety reasons. Usually done this overpressure protection by a safety valve. In the case of a request, there is a certain probability for "that the valve no longer closes after a pressure drop and remains open incorrectly. That means uncontrolled and undesired loss of pressure and inventory of the secured component or system. One Blocking option that prevents the function of the safety valve is not permitted.

Die Erfindung stellt sich die Aufgabe eine Absperrmöglichkeit YUr die von dem Sicherheitsventil wegführende Abblaseleitung zu schaffen, welche die Funktion des Sicherheitsventils nicht gefährdet.The object of the invention is to provide a shut-off option for the blow-off line leading away from the safety valve to create that does not endanger the function of the safety valve.

Gelöst wird die Aufgabe erfindungsgemäß dadurch, daß in der Abblaseleitung eine Absperrarmatur eingebaut ist, daß die Absperrarmatur von einer Bypassleitung umfahren ist, die mit einer Berstscheibe verschlossen ist.The object is achieved according to the invention in that a shut-off valve is installed in the blow-off line the shut-off valve is bypassed by a bypass line that is closed with a bursting disc.

Diese Anordnung gestattet eine zuverlässige Absperrung der vom Sicherheitsventil wegführenden Leitung im Falle des Nichtschließens nach erfolgter Druckabsenkung. Bei fehlerhaftem Schließen der Absperrarmatur spricht bei überdruck die Berstscheibe an und stellt die Druckentlastung des entsprechenden Anlagenteiles sicher.This arrangement allows a reliable shut-off of the line leading away from the safety valve in the case of Failure to close after the pressure has been reduced. If the shut-off valve closes incorrectly, overpressure speaks the rupture disc and ensures the pressure relief of the corresponding part of the system.

Anhand eines Ausführungsbeispiels und einer schematischen Zeichnung wird der Aufbau und die Funktion der erfindungsgemäßen Einrichtung beschrieben.Using an exemplary embodiment and a schematic drawing, the structure and function of the inventive Facility described.

In eine von einem druckbelasteten Anlagenteil 1 wegführende Leitung 2 ist ein eigenmediumgesteuertes Sicherheitsventil 3 eingebaut. Von der Leitung 2 führt eine Irapulsleitung 4 zum Steuerventil 5 welches über die Steuerleitung 6 die Öffnung des Sicherheitsventils 3 in bekannter Weise auslöst. Über die vom Sicherheitsventil 3 wegführende Abblaseleitung wird durch die offene Absperrarraatur 8 der Überdruck des Anlagenteiles 1 gesenkt. Sollte nach erfolgter Druckabsenkung das Sicherheitsventil 3 nicht in seine Schließstellung~zurückgehen, wird zur Vermeidung eines unerwünschten Druck- und Inventarverlustes des abgesicherten Anlagenteiles 1 die Absperrarmatur 8 geschlossen.
Für den Fall des fehlerhaften Schließens der Absperrarmatur stellt die in einer die Absperrarmatur umfahrenden Bypassleitung 9 angeordnete Berstscheibe 10 die Druckabsenkung des Anlagenteiles sicher.An internal medium-controlled safety valve 3 is installed in a line 2 leading away from a pressurized system part 1. An IRA pulse line 4 leads from the line 2 to the control valve 5 which, via the control line 6, triggers the opening of the safety valve 3 in a known manner. Via the blow-off line leading away from the safety valve 3, the overpressure of the system part 1 is reduced by the open shut-off device 8. If, after the pressure has been reduced, the safety valve 3 does not return to its closed position, the shut-off valve 8 is closed in order to avoid an undesirable loss of pressure and inventory in the protected system part 1.
In the event that the shut-off valve closes incorrectly, the rupture disc 10 arranged in a bypass line 9 that bypasses the shut-off valve ensures that the pressure in the part of the system is reduced.

Mit der erfindungsgemäßen Einrichtung ist die Absperrung eines Sicherheitsventils bei dessen nicht ordnungsgemäßen Schließen möglich, ohne die Funktion des Sicherheitsventils im Anforderungsfall durch Fehlbedienung der Absperrarmatur zu verhindern. With the device according to the invention, the barrier is one Safety valve possible if it does not close properly, without the function of the safety valve when required to prevent incorrect operation of the shut-off valve.
