Abstract

Un conjunto de asiento y chapaleta para uso en una válvula de retencion que tiene un alojamiento con un lado corriente arriba y un lado corriente abajo, en donde la válvula de retencion está adaptada para impedir el retroflujo en una trayectoria de flujo cuando la presion de flujo regular corriente arriba cae en un nivel predeterminado, este conjunto comprende: un miembro de asiento en general en forma de anillo que tiene un pasaje a través y colocado dentro del alojamiento, de tal manera que el pasaje forma parte de la trayectoria de flujo; el miembro de asiento está formado a partir de una pieza unitaria de material y comprende una superficie de base plana colocada en el alojamiento con la superficie de base plana vuelta hacia arriba, una superficie de sellamiento superior plana angulada hacia arriba y medios conectores formados sobre la superficie plana superior para conectar una tapa de chapaleta movil al miembro de asiento; la tapa de chapaleta comprende una superficie de sellamiento de chapaleta adaptada para acoplarse herméticamente con la superficie de sellamiento superior del miembro de asiento para detener el retroflujo cuando la presion de flujo regular corriente arriba cae a un nivel predeterminado, causando que la tapa de chapaleta descanse en la posicion cerrada. La invencion incluye un conjunto de válvula de retencion que incorpora el conjunto de asiento y chapaleta.
