Abstract

DISPOSITIVO PARA VERIFICAR EL CIERRE METODICO DE VALVULAS DE MARIPOSA INERCEPTORAS EN INSTALACIONES DE TURBINAS DE VAPOR. CONSTA DE UNA TUBULADURA (8) EN LA QUE AL ESTRANGULADOR (81) LE LLEGA EL VAPOR VIVO (86) A PRESION CONSTANTE; DICHO VAPOR (86) CIRCULA A TRAVES DEL TALADRO DE MEDICION (80) Y PASA AL INTERIOR DE LA CARCASA DE LA VALVULA (4). EN LA ULTIMA PARTE DEL MOVIMIENTO DE CIERRE DE LA MARIPOSA (5) SE APROXIMA LA SUPERFICIE DE REBOTAMIENTO (51) A LA DESEMBOCADURA DEL TALADRO DE MEDICION (80); AL REDUCIRSE LA SECCION TRANSVERSAL DE ESTRANGULACION, AUMENTA LA PRESION EN EL TALADRO (80). EL AUMENTO DE PRESION SE CONDUCE A TRAVES DE LA BIFURCACION (83) A UN TRANSFORMADOR MEDIDOR DE PRESION.
