Abstract

UNA VALVULA DE CONTROL DE CARRERA PARA UNA BOMBA DE EMBOLOS RADIALES.SE EMPLEA PARA CONTROLAR LA COMUNICACION DE FLUIDO DE LA CAMARA DE CONTROL DE CARRERA (32) DE UNA BOMBA PRINCIPAL (12) DE EMBOLOS RADIALES QUE ES ALIMENTADA POR UNA BOMBA DE CARGA (14). LAS SALIDAS DE AMBAS BOMBAS ESTAN CONECTADAS A ENTRADAS DIFERENTES (26, 28) DE LA VALVULA, LA CUAL TIENE TAMBIEN UNA SALIDA (30) A LA CAMARA (32). A UNA PRSION ALTA DE SALIDA DE LA BOMBA PRINCIPAL (12), LA VALVULA (20) SE MUEVE, CONECTANDO ESTA SALIDA A LA SALIDA (30) PARA ANULAR LA CARRERA, EN TANTO QUE AL MISMO TIEMPO BLOQUEA LA ENTRADA (26) DESDE LA BOMBA DE CARGA (14) POR UNA VALVULA DE RETENCION (44, 46). A BAJA PRESION, LA VALVULA (20) RETROCEDE, Y LA SALIDA DE LABOMBADE CARGA ES CONECTADA A LA CAMARA (32).
