Abstract

VALVULA DE RECIRCULACION DE BAJA PRESION PARA ENFRIAR BOMBAS CENTRIFUGAS, COMPRENDIDA POR UNA CAJA DE VALVULA UNITARIA DIVIDIDA EN DOS CAMARAS CON UN ORIFICIO DE ENTRADA DE FLUIDOS EN LA PRIMERA Y OTRO DE EXPULSION EN LA SEGUNDA, TENIENDO LA PRIMERA UN ORIFICIO DE RECIRCULACION PARA REDIRIGIR FLUIDOS DE RETORNO A LA BOMBA. UNA VALVULA DE RETENCION DE PIEZAS MULTIPLES ENTRE AMBAS CAMARAS, PERMITE EL PASO DEL FLUIDO DE LA PRIMERA A LA SEGUNDA, IMPIDIENDO EL RETORNO. UN VASTAGO DESLIZABLE ACOPLADO A LA VALVULA DE RETENCION EXISTENTE A TRAVES DE LA PRIMERA CAMARA MUEVE LA VALVULA DE RETENCION DE ABIERTA A CERRADA. MEDIOS ACOPLADOS A DICHO VASTAGO DESVIAN AL MISMO A LA POSICION CERRADA, Y MEDIOS DE VALVULA DE RECIRCULACION ACOPLADOS AL ANTERIOR, ABREN Y CIERRAN EL ORIFICIO DE RECIRCULACION, ABRIENDOSE CUANDO LOS MEDIOS DE VALVULA DE RETENCION ESTAN CERRADOS Y A LA INVERSA.
