Abstract

Un dispositivo de descarga de presión (100) para una válvula de aislamiento bidireccional que comprende un cuerpo (102) con una cavidad de la válvula, teniendo dicho cuerpo un recipiente, formado en el mismo, un disco (104) dispuesto en la sección central del mencionado recipiente, estando interpuesto dicho disco (104) entre dos asientos (108a, 108b) activados mediante resortes, cada uno de dichos asientos en comunicación fluida con los lados opuestos de la válvula (A, B), dicho recipiente sección central en fluida comunicación con dicha cavidad de cuerpo de la válvula, donde dicho disco (104), está montado de manera recíprocamente movible en dicho recipiente sección central y en donde cada uno de dichos asientos (108a, 108b) es un asiento flotante y está provisto de dos diferentes tipos de juntas en serie, por el que la sobrepresión en la cavidad del cuerpo de la válvula provoca la retracción del asiento del lado de la válvula (A, B) donde la presión es más alta, para de esta manera aliviar la sobrepresión de la cavidad del cuerpo de la válvula hacia el lado de la válvula (A, B) donde la presión es más elevada.
