Abstract

SE PRESENTA UNA VALVULA, TAL COMO UN COMPRESOR O UNA VALVULA DE SERVICIO DE TUBERIAS, A UTILIZAR EN CIRCUITOS PARA FLUIDOS DE REFRIGERACION O ACONDICIONAMIENTO DEL AIRE QUE TIENEN UN FLUJO MEJORADO PARA MEJORAR EL RENDIMIENTO ENERGETICO. LA VALVULA TIENE INCORPORADO UN MIEMBRO DE BOLA ROTATIVO (24) CON UN DIAMETRO DEL ORIFICIO DE PASO PARA LOS FLUIDOS DE 90 (GRADOS) IGUAL O MAYOR QUE EL DIAMETRO DE LA TUBERIA PARA FLUIDOS A LA QUE SIRVE. LA ROTACION DE UN VASTAGO ACCIONADOR PRIMARIO (44) HACE ROTAR EL MIEMBRO DE BOLA PARA ABRIR Y CERRAR AL VALVULA. UNA JUNTA DE ESTANQUEIDAD DE BOLA ANULAR (34) PROPORCIONA UN ASIENTO CONTRA EL QUE LA BOLA SE PUEDE HERMETIZAR POSITIVAMENTE. UN VASTAGO SECUNDARIO (72) SE ENCUENTRA ALIENADO EN UN EJE ALTERNATIVO (1) DESDE EL VASTAGO PRIMARIO QUE ES PREFERENTEMENTE COLINEAL A LA TUBERIA PARA FLUIDOS. EL VASTAGO SECUNDARIO LLEVA A CABO UN ACOPLAMIENTO POSITIVO ENTRE EL MIEMBRO DE BOLA ROTATIVO Y LA JUNTA DE ESTANQUEIDAD DE BOLA. UN EMBOLO (36) COOPERA CON UNAS INDENTACIONES POSICIONADORAS (28) Y UNA RANURA DEL MIEMBRO DE BOLAS ROTATIVO PARA CENTRAR LA BOLA DENTRO DE LA VALVULA Y ALINEAR SU ORIFICO DE PASO PARA LOS FLUIDOS CON LOS CONECTORES DE LAS TUBERIAS PARA FLUIDOS. LAS INDENTACIONES POSICIONADORAS ASEGURAN TAMBIEN QUE EL MIEMBRO DE BOLA ROTATIVO QUEDE ORIENTADO DE FORMA CORRECTA CUANDO SE ENCUENTRA BIEN EN UNA POSICION ABIERTA O EN UNA CERRADA. CUANDO EL VASTAGO SECUNDARIO SE ACOPLA, LLEVA A CABO UNA FUERZA DE CIERRE POSITIVA PARA CERRAR EL MIEMBRO DE BOLA CONTRA LA JUNTA DE ESTANQUEIDAD DE BOLA.
