Abstract

UNA VALVULA DE CORTE O CIERRE, ESPECIALMENTE UNA VALVULA DE BOLA, COMPRENDE UN CUERPO DE VALVULA (2) QUE TIENE AL MENOS UNA SUPERFICIE OBTURADORA ANULAR DISEÑADA PARA ENCAJARSE CONTRA UN OBTURADOR (5) SOPORTADO POR UN ANILLO DE UN ASIENTO SUJETO DE MANERA AXIALMENTE DESPLAZABLE. EL ANILLO DEL ASIENTO (3) O CADA ANILLO DEL ASIENTO, ESTA ADAPTADO, RESPECTIVAMENTE, PARA SER EMPUJADO HACIA LA POSICION OBTURADORA, EN LA QUE SU ASIENTO (5) COOPERA Y SE PONE EN CONTACTO CON EL CUERPO DE LA VALVULA (2), A TRAVES DE LA FUERZA INTERMEDIA DE UN MUELLE (4) Y / O LA PRESION DE UN FLUIDO (POR MEDIO DE 6). PARA MEJORAR LA FUNCION OBTURADORA Y HACER POSIBLE LA ADAPTACION DE LAS PERDIDAS ENTRE EL CUERPO DE LA VALVULA Y DICHOS ASIENTOS, EL ANILLO DEL ASIENTO O CADA UNO DE DICHOS ANILLOS DE ASIENTO SE ASIGNA, RESPECTIVAMENTE, AL MENOS UN ANILLO DE ASIENTO ADICIONAL SEPARADO (11) SUJETO DE FORMA AXIALMENTE DESPLAZABLE Y DE MANERA INDEPENDIENTE SOBRE EL PRIMER ANILLO DE ASIENTO MENCIONADO (3). EL ANILLO DEL ASIENTO (11) ADICIONAL SEPARADO PUEDE ESTAR DISPUESTO DE FORMA CONCENTRICA CON EL PRIMER ANILLO DEL ASIENTO MENCIONADO (3).
