Abstract

PARA EVITAR EN UNA VALVULA DE CIERRE DE GAS (18) PARA INSTALACIONES DE ELABORACION DE PLASTICO, UNA FORMACION DE VELO EN EL PROPIO INYECTADO EN PRESIONES DE GAS MUY ELEVADAS Y GARANTIZAR UNA ELEVADA FLEXIBILIDAD EN LA PRODUCCION SIN TIEMPOS DE PREPARACION SE PROPONE UN GOBIERNO DE LA AGUJA DE VALVULA (40) POR UN EMBOLO DE MANDO (60) QUE POR SU PARTE SE MANDA POR UN VOLUMENT DE GAS DE TRABAJO. EN LA CONDUCCION DE MASA A LA HERRAMIENTA (16) SE CIERRA LA AGUJA DE VALVULA (40) HERMETICAMENTE A LA MASA, MIENTRAS EN LA RECONDUCCION DE GAS LA AGUJA DE VALVULA (40) PERMANECE ABIERTA HASTA QUE SE VACIE TOTALMENTE LAS BURBUJAS DE GAS FORMADAS EN EL ESPACIO HUECO DE LA HERRAMIENTA (16)
