Abstract

Un dispositivo de válvula de diafragma , que comprende un cuerpo de válvula que define un asiento de válvula, y un diafragma de cierre que, junto con el cuerpo de válvula, define un paso de flujo a través de la válvula y que es movible entre una posición cerrada, en la que está en contacto de obturación con el asiento para cerrar el paso al flujo de fuido, y una posición totalmente abierta, en la que está espaciado desde el asiento, caracterizado porque el diagrama incluye al menos una lengüeta que se proyecta hacia el interior del paso de flujo junto a la parte del diafragma que obtura contra el asiento de válvula para actuar como deflector a fin de impedir el flujo a través de la válvula cunado la válvula está parcialmente abierta y el diafragma está cerca del asiento, en comparación con la posición totalmente abierta.
