Abstract

En boresikringsventil (10) er anordnet med en forbedret tetningsenhet (34) for tettende Inngrep med et rør som forløper gjennom boreslkrlngsventllen og ned l en brønnboring. Tetningsenheten (34) Innbefatter en elastomer tetning og et antall omkretsmesslg avstands- bellggende metalllnnsatser (50) Inne l tetnlngen (34) for vesentlig å minske eller hindre ekstruderlng av tetnlngen under høye fluldtrykk. Boreslkrlngsventllen kan med stor sikkerhet benyttes for tettende Inngrep med rør av varierende diametere. Hver Innsats (50) har et hovedsakelig I-formet utseende med en øvre flens (52), en nedre flens (54) og en ribbe (56) som fast sammenknytter f lensene (52, 54). En spalt (68) er anordnet l minst en av flensene og danner et hulrom for opptak av et hann-sammenkobllngselement (84) som forløper omkretsmesslg fra en tilstøtende innsats (50), slik at de omkretsmesslg avstandsbellggende Innsatser blir sammenknyttet for å minske ekstruderingsgapene mellom Innsatsene og for bedre å la tetnlngsenheten (34) danne en positiv tetning med røret.
