Abstract

En forbedret indre tetningsenhet i (100) en avstenger (50) som anvendes i utblåsningssikringer (10) av stempelventiltypen er beskrevet. Den beskrevne oppfinnelsen tilveiebringer en indre tetningsenhet med styring (100) som omfatter et spesialutformet styreorgen (110) og et separat tetningselement (130). Når utblåsningssikringen (10) av stempelventiltypen lukkes, blir to motstående avstengere (50) beveget mot hverandre, og den indre tetningsenheten med styring (100) fører en kabel (eller annen rørdel) mot midten av den vertikale boringen gjennom utblåsningssikringen (10). Det at den indre tetningsenheten med styring (100) befinner seg nær ved avstengerorganets(50) senterakse bidrar til å sikre at det dannes en positiv forsegling og at det ikke oppstår skade på anordningen i den sentrale boringen i utblåsningssikringen (10). Det separate, spesialformede tetningselementet (100) kan enkelt settes inn i og fjernes fra styreorganet(110) i den indre tetningsenheten med styring (100) for enkel utskiftning.
