Abstract

El sistema de despresurización se caracteriza porque comprende una válvula principal (8) provista de un actuador neumático con un muelle de apertura (10) que puede estar conectada por un extremo al un recipiente presurizado (1) que aloja un gas en su interior y por el otro extremo a la atmósfera, definiendo dicho muelle de apertura (10) una presión mecánica predeterminada, de manera que cuando la presión en el interior del recipiente presurizado (1) es mayor que la presión mecánica predeterminada dicha válvula principal (8) está cerrada, y cuando la presión en el interior del recipiente presurizado (1) es menor que la presión mecánica predeterminada dicha válvula principal (8) está abierta, dejando que el gas del recipiente presurizado (1) salga a la atmósfera. No requiere de aporte de energía exterior, lo que le permite responder adecuadamente a su función incluso en escenarios de accidente con pérdida total de energía eléctrica.
