Abstract

Válvula de regulación con disparo automático, que comporta un elemento de obturación móvil, susceptible de desplazarse entre una posición de cierre, en la que el citado elemento de obturación cierra de manera estanca una abertura prevista en un recinto, y una posición de apertura, en la que el citado elemento está alejado de la abertura aludida; comportando, asimismo, un órgano destinado a ejercer una contrapresión sobre el elemento de obturación, a fin de mantenerlo en su posición de cierre cuando la presión reinante en el interior del recinto es inferior a una presión predeterminada, caracterizada porque el citado órgano está constituido por un cilindro neumático que actúa sobre el elemento de obturación con el intermedio de un enlace que incluye unos elementos de acoplamiento susceptibles de desacoplar al cilindro neumático con respecto al elemento de obturación en el caso de un aumento rápido de la presión reinante en el interior del recinto.
