Abstract

Una valvula de control de fluido primaria de alta presion y una valvula de control de fluido selectora de multiples presiones se describen para operar un dispositivo accionado por fluido. De preferencia, una bola esferica de desplazamiento vertical y un asiento de valvula frustoconico adaptado para contacto substancial de linea entre ellos, se proporcionan con un area de flujo corriente arriba adyacente al contacto de linea, a fin de minimizar substancialmente el dano de flujo sonico a la superficie de sello actual del asiento de valvula al desplazarlo lejos del asiento de contacto de linea. De preferencia, la bola de desplazamiento vertical es movible dentro de una guia de desplazamiento vertical que se permite para flotar radialmente, a fin de permitir que la bola con desplazamiento vertical sea substancialmente autocentrante con respecto al asiento de valvula. Ademas, la fuga de cruce se impide de preferencia, al cerrar una bola de desplazamiento vertical de descarga justo antes de abrir una bola de desplazamiento vertical de suministro. Estos principios y caracteristicas son igualmente aplicables a cualquiera o a ambas de las valvulas de control de fluido selectora de multiples presiones o primaria.
