Abstract

EL DIAFRAMA (2) VA PROVISTO EN LA PARTE EXTERIOR DE UN DISPOSITIVO ANULAR DE APERTURA (15) FIJADO AL DIAFRAGMA. EL DISPOSITIVO ANULAR PUEDE SER COLOCADO ENTRE DOS REBORDES (17,18) QUE SE EXTIENDEN INTERIORMENTE DISPUESTOS EN LA PARED INTERIOR DEL TANQUE DE EXPANSION. LOS REBORDES ESTAN SEPARADOS Y SE EXTIENDEN PERPENDICULARMENTE A LA LINEA CENTRAL DEL TANQUE (16). EL DIAFRAGMA TIPO AMPOLLA (2) SE COMPONE DE DOS PARTES (19,20) UNIDAS ENTRE SI POR SUS BORDES (21,22) MERCED A UN ANILLO DE APERTURA (5) DE SECCION TRANSVERSAL EN U. LOS BORDES (21,22) DEL DIAFRAGMA (19,20) SE ACOMODAN EN LA U Y SE UNEN POR SUS BRAZOS (23,24). EN LA SITUACION DE TRABAJO SE PUEDE CONTROLAR LA FORMA DEL DIAFRAGMA DE MODO QUE EN UNA FORMA OPTIMA SE OBTIENE LA TENSION DEL DIAFRAGMA.
