Abstract

Oppfinnelsen angår en testplugg (10) fortetting av en utboring (12) i en rørhenger (14), omfattende et ringformet plugglegeme (20) som har en gjennomgående ak-siell utboring (22), hvor den aksielle utboring (22) danner et avsmalnende ringformet sete (24) og et forstørret mottak (26) inne i plugglegemet (20), et antall støttedogger (28) som er fjernbart montert inne i tilsvarende spor (30) utformet i plugglegemet (20) nær en nedre del av mottaket (26); en spindel (36) som er glid-bart mottatt inne i mottaket (26), hvor spindelen (36) har en nedad- og utadvendt kamoverflate (60) utformet på en nedre del; og en tapp (62) som har en avsmalnende lukningsdel (66) tilpasset til å mottas i det ringformede sete (24) en fjær (74) å forspenne lukningsdelen (66) mot setet (24) og en pakningsring (80) for å danne en fluidum-tett pakning mellom lukningsdelen (66) og setet (24); hvor hver støttedogg (28) omfatter en indre skrå kant (92) utformet på en øvre del, som for-trinnsvis passer til kamoverflaten (60) på spindelen (36), slik at når spindelen (36) blir satt, vil kamoverflaten (60) engasjere den skrå kanten (92) og tvinge støtte-doggene (28) inn i en ringformet forsenkning (16) utformet i rørhengeren (14) for dermed å sikre testpluggen (10) inne i rørhengeren (14); og hvor spindelen (36) omfatter en innadgående ringformet krave (40) og tappen (62) omfatter en utad-gående ring som danner en nedadvendt ringformet skulder (70) som overlapper kraven (40) ovenfor lukningsdelen (66), slik at lukningsdelen (66) ikke vil tette mot det ringformede sete (24) hvis ikke spindelen (36) er helt satt, og spindelen (36) vil utløse lukningsdelen (66) fra det ringformede sete (24) under uthenting av testpluggen (10), for dermed å utjevne trykket ovenfor og nedenfor testpluggen (10).
