Abstract

En avlastningsventil særlig for avlastning av det superatmosfæriske trykket i en tank for brennbare væsker og som omfatter en pilotventilenhet (6) med en innløpsåpning (9) og en utløpsåpning (10). Ved et forbestemt justerbart superatmosfærisk trykk i tanken åpner pilotventilenheten (6) og tillater en gasstrøm fra innløpsåpningen (9) til utløpsåpningen (10), noe som på den ene side forsterker ventilen for å åpne hurtig og på den annen side medfører at et kammer (15) er tømt for gass. Kammeret (15) er lukket med en membran (3) som styrer et ventillegeme (2) mot eller bort fra et ventilsete (1) til virkningen av at det er mulig å tillate eller blokkere en strøm av gass mellom et rom (13) og en avlastningspassasje (5). I samsvar med oppfinnelsen er avlastningspassasjen (5) åpen mot utsiden via en overtrykkventil (l 1), og utløpsåpningen (10) fra pilotventillegemet (6) er koplet til avlastningspassasjen (5). Med disse innslagene er det oppnådd en forbedret forsterkervirkning, likeledes en høyere grad av sikkerhet at en brann ikke kan omflyttes fra utsiden og inn i avlastningspassasjen (5) og hulrommet (13).
