Abstract

En hette for et undervanns ventiltre som har en gjeninntredelsesstuss (1), og for bruk med en rørhenger (25) plassen inne i ventiltreet omfatter en ytre hylse (3) for pasning over stussen og en indre hylse (19) innrettet til å forløpe inne i stussen. Hylsen har kommunikasjonskoplere (27, 37) for samvirke med rørhengeren. Med fordel befinner kommunikasjonskoplerne seg i enden av den indre hylsen. Koplerne kan oppta blindplugger eller aktive kopiere for å passe til applikasjonen. Den indre hylse (19) bærer minst en ringformet tetning (21, 22) som gir en barriere mellom den indre hylse og den indre omkrets av stussen. Den ytre hylse (3) innbefatter frigjørbare inngrepsansatser (16) for å feste den ytre hylse til navet. Hetten er tilpasset for bruk som et innsettingsverktøy.
