Abstract

Et røykspjeld er beskrevet omfattende en hovedsakelig rektangulær ramme installerbar i en ventilasjonsluftkanal, rammen har skråstilt montert derpå i det minste en roterbar lamell (2), lamellen(e) er roterbare ved hjelp av en separat mekanisme med omtrent 90 º mellom en åpen posisjon og en lukket posisjon, lamellen har en første lang sidekant (2') og en andre lang sidekant (2") som den motsatte lamellsidekanten relativ til den første sidekanten, og lamellene videre har festet dertil en elastisk forsegling (3) og en ekspanderende tetningsmasse (4), hvorved den elastiske forseglingen (4) er festet i det minste på den første lange sidekanten (2') av lamellen for å strekke seg hovedsakelig over hele lengden av lamellsidekanten. Oppfinnelsen implementeres ved at den ekspanderende tetningsmassen (4) i det minste er festet på den andre sidekanten (2") av lamellen (2) for å strekke seg hovedsakelig over hele lengden av lamellsidekanten og at den ekspanderende tetningsmassen (4) er dekket av en kontinuerlig strimmeldel (7) i stand til å bevege seg ut utover fra den lange lamellsidekanten når den ekspanderende tetningsmassen sveller. ?? ?? ?? ?? 1A smoke damper is disclosed comprising a substantially rectangular frame installable in a ventilation air duct, the frame inclined thereon at least one rotatable lamella (2), the lamella (s) rotatable by a separate mechanism of about 90 ° between an open position and a closed position, the lamella has a first long side edge (2 ') and a second long side edge (2 ") as the opposite lamella side edge relative to the first side edge, and the lamellae have further attached thereto an elastic seal (3) and an expanding sealant ( 4), whereby the resilient seal (4) is secured at least to the first long side edge (2 ') of the lamella to extend substantially over the entire length of the lamellar side edge.The invention is implemented by at least the expanding sealant (4) is attached to the second side edge (2 ") of the slat (2) to extend substantially the entire length of the slab side edge and that the expanding sealant (4) is covered by a continuous strip member (7) capable of moving outwardly from the long slab side edge as the expanding sealant swells. ?? ?? ?? ?? 1
