Abstract

dispositivo e processo de controle para uma válvula de fechamento rápido de uma turbina a va- a presente invenção refere-se a um dispositivo de controle para uma válvula de fechamento rápido (2) de uma turbina a vapor, com uma vál-vula de descarga (4) para redução de um pressão hidráulica, que abre a vál-vula de fechamento rápido, e uma disposição de válvula de controle de vál-vula de descarga (6) com pelo menos três válvulas, que estão conectadas hidraulicamente de tal modo com a válvula de descarga que a mesma só fecha a válvula de fechamento rápido quando pelo menos duas válvulas da disposição de válvula de controle de válvula de descarga são manobradas para uma posição de fechamento rápido, apresenta uma disposição de vál-vula de controle de teste (8, 9) para a redução e aumento opcional da pressão hidráulica, que abre a válvula de fechamento rápido, com a válvula de descarga estando fechada.
