Title (EN) PRESSURE RELIEF VALVE FOR PRESSURISED FURNACE
(FR) SOUPAPE DE DÉCHARGE POUR FOUR SOUS PRESSION
Abstract:
(EN) A pressure relief valve system comprises a fluid outlet (1) from a pressure vessel; a flexible expansion piece (4) at an end of the fluid outlet remote from the pressure vessel; a primary pressure relief valve comprising a valve seat and a valve lid (7). The valve seat comprises a flange (5) mounted on the expansion piece and the valve lid is adapted to form a valve seal with the flange. The system further comprises a fluid off-take (13) connected to the fluid outlet (1) and a secondary pressure relief valve (11) to receive fluid from the fluid off-take. The secondary pressure relief valve comprises an outlet (12) coupled to a valve opening actuator (15), whereby passage of fluid through the secondary pressure relief valve (11) causes the opening actuator to operate to open the valve lid (7).
(FR) L'invention concerne un système soupape de décharge, comprenant une sortie de fluide (1) d'un récipient sous pression ; une pièce de détente flexible (4) à une extrémité de la sortie de fluide à distance de la cuve sous pression ; et une soupape de décharge primaire comprenant un siège de soupape et un clapet de soupape (7). Le clapet de soupape comprend une bride (5) montée sur la pièce de détente et le clapet de soupape est conçu pour former un joint d'étanchéité de soupape avec la bride. Le système comprend en outre une prise de fluide (13) raccordée à la sortie de fluide (1) et une soupape de décharge secondaire (11) pour recevoir du fluide en provenance de la prise de fluide. La soupape de décharge secondaire comprend une sortie (12) accouplée à un actionneur d'ouverture de soupape (15), moyennant quoi le passage de fluide dans la soupape de décharge secondaire (11) amène l'actionneur d'ouverture à fonctionner pour ouvrir le clapet de soupape (7).
