Abstract

Un dispositivo de seguridad para válvulas y/o contenedores bajo presion que comprende: un cuerpo en el que se provee un pasaje conectable a una fuente de gas presurizado, un obturador que se puede trasladar con respecto al cuerpo entre una posicion cerrada, en la que un extremo del obturador cierra el pasaje, y una posicion abierta, en la que el obturador se distancia de dicho pasaje de forma tal de permitir la salida de gas de la fuente hacia afuera, a la atmosfera. El obturador comprende medios de retencion para trabar al obturador en la posicion cerrada, que son al menos parcialmente deformables por el efecto del aumento en la temperatura ambiente por sobre una temperatura umbral para permitir el desplazamiento del obturador a la posicion abierta.A safety device for valves and / or containers under pressure comprising: a body in which a passage can be connected to a source of pressurized gas, a shutter that can be moved with respect to the body between a closed position, in which one end of the shutter closes the passage, and an open position, in which the shutter distances itself from said passage in such a way as to allow the gas to escape from the source to the atmosphere. The shutter comprises retaining means for locking the shutter in the closed position, which are at least partially deformable by the effect of the increase in ambient temperature above a threshold temperature to allow the shutter to move to the open position.
