Abstract

En indikator for ventilstilling (10) for indikering av en åpen eller lukket stilling av en ventil med et ventil- skaft, hvor indikatoren omfatter et legeme (18) beregnet for å bli montert på en undersjøisk ventiltrekonstruksjon, en løpeblokk (26) bevegelig forbundet med legemet (18) av minst en føringsbolt (32), hvor løpeblokken (26) har et gjen- get hull (28) for innkopling av et gjen- get forlengelsesskaft (14) som er koplet til ventilskaftet, hvor et stivt rør (36) er forbundet med legemet (18) og har første og andre åpne ender (42, 44) og en skruefjær (59) har en ende for- bundet med løpeblokken (26) og den andre ende strekker seg gjennom den første ende (42) av det stive rør (36), idet forlengelsen av fjæren (50) forbi den andre ende (44) med en forutbestemt verdi tilveiebringer en visuell indi- kering at ventilen er i dens åpne eller lukkede stilling, hvor bevegelse av løpeblokken (26) som reaksjon på aktiv- isering av ventilen vil skyve eller trekke fjæren (50) gjennom røret (36) for å tilveiebringe den ønskede visuelle indikering.
