Abstract

VALVULA DE SEGURIDAD. CONSTA DE UNA CLAPETA, EMPUJADA POR UN RESORTE CONTRA UN ASIENTO, PARA OBTURAR UN CONDUCTO QUE COMUNICA LA ENTRADA Y LA SALIDA. UN FRENO HIDRAULICO DE AMORTIGUACION DE LAS OSCILACIONES DE LA CLAPETA Y QUE CONSTA DE UN DIAFRAGMA MOVIL QUE SEPARA EN UN CILINDRO DOS CAMARAS DE VOLUMEN VARIABLE RELLENAS DE LIQUIDO. DICHO DIAFRAGMA LLEVA UN VASTAGO CONECTADO POR UNA PARTE CON LA CLAPETA Y POR OTRO CON EL VASTAGO SOBRE EL QUE SE EJERCE LA ACCION DEL RESORTE TARADO. EL VASTAGO ACOPLADO AL DIAFRAGMA MOVIL FORMA SALIENTE A TRAVES DE LOS FONDOS DEL CILINDRO, EN LOS CUALES EXISTEN UNA JUNTAS TORICAS QUE ACTUAN CONJUNTAMENTE CON EL VASTAGO. EL DIAFRAGMA ESTA CONSTITUIDO POR UN PISTON DESLIZANTE EN EL INTERIOR DEL CILINDRO.
