Abstract

Una válvula de secuencia que tiene un primer estado en el que un primer tubo flexible está ocluido y un segundo tubo flexible no lo está y un segundo estado en el que el segundo tubo está ocluido y el primer tubo no lo está siendo la válvula de secuencia ajustable manualmente al primer estado y conmutando al segundo estado en respuesta a una señal de control, comprendiendo la válvula de segunda un aplastador o pinzador de tubo pivotable para pinzar o aplastar el primer tubo cuando la válvula está en el primer estado y el aplastador de tubo está en una primera posición y a continuación el segundo tubo flexible cuando la válvula está en el segundo estado y el aplastador de tubo está en una segunda posición; medios de carga para aplicar una fuerza de carga al aplastador de tubo en dirección hacia la segunda posición; medios movibles manualmente conectados al aplastador de tubo para, mover el aplastador de tubo contra la fuerza de carga a la primera posición en la que es aplastado el primer tubo; un retén o fiador pivotable para aplicarse al aplastador de tubo y mantenerlo en la primera.posición en que el primer tubo está aplastado; y un solenoide que libera el retén en respuesta a la señal de control para permitir que el retén pivote fuera de aplicación con el aplastador de tubo y por ello permita a la fuerza de carga hacer pivotar el aplastador de tubo a una posición en que el segundo tubo está aplastado.
