Title (EN) FIRE ISOLATION DEVICE
(FR) DISPOSITIF D'ISOLATION CONTRE LE FEU
Abstract: front page image
(EN)A fire isolation device capable of operating at high temperatures having a valve poppet (14) designed to close after a given temperature has been reached by a fusible nose member (13). The valve poppet (14) being biased by a spring (15) toward a seat (12) to a valve closed position. At least one aperture (18) through the nose member (13) provides for continuous fluid flow through the device around the valve poppet (14), and the nose member (13) is positioned to hold the valve poppet (14) in an open position against the bias of the spring (15).
(FR)Un dispositif d'isolation contre le feu, susceptible de fonctionner à des températures élevées, comporte un champignon de soupape (14) destiné à se fermer une fois qu'une température donnée est atteinte par un talon fusible (13). Le champignon de soupape (14) est sollicité par un ressort (15) en direction d'un siège (12), dans une position fermée de la soupape. Au moins une ouverture (18) traversant le talon (13) assure un écoulement continu de fluide à travers le dispositif autour du champignon de soupape (14), et le talon (13) est positionné pour maintenir ledit champignon (14)en position ouverte à l'encontre de la sollicitation du ressort (15).
