Abstract

Det er beskrevet en beskyttelsesanordning for påvisning og senkning av overtrykk i en fluidrørledning som har en fluidinngangsende (3) og en fluidutgangsende (4), idet fluidinngangsenden under drift er forbundet med en fluidkilde. Anordningen omfatter: - første og andre rørledningsventiler (1, 2) koblet i serie langs rørledningen, idet den første rørledningsventil er plassert nærmere inngangsenden (3) enn den andre, og hvor rørledningsventilene er uavhengig svitsjbare mellom åpne stillinger hvor fluidstrømning gjennom rørledningen er tillatt, og lukkede stillinger hvor denne fluidstrømning er blokkert, - en trykktransduser (5, 6, 7) for å bestemme fluidtrykket i rørledningen på et sted mellom den første og andre rørledningsventil (1, 2), - et omløpsrør som har en første ende forbundet med rørledningen mellom inngangsenden (3) og den første rørledningsventil (1), og en andre ende forbundet med rørledningen mellom den første og andre rørledningsventil (1, 2), - en omløpsventil (9) plassert langs omløpsrøret, som kan svitsjes mellom en åpen posisjon hvor fluidstrømning gjennom omløpsrøret tillates og en lukket posisjon hvor denne fluidstrømning er blokkert, - et ventilasjonsrør forbundet med omløpsrøret mellom omløpsventilen (9) og den andre ende av omløpsrøret, og som fører til et ventileringsutstyr, og - en ventileringsventil (12) plassert langs ventileringsrøret, som kan svitsjes mellom en åpen posisjon hvor fluidstrømning gjennom ventileringsrøret tillates og en lukket posisjon hvor denne fluidstrømning er blokkert.
