Abstract

EN UNA TUBERIA DE DOBLE PARED, CON UN TUBO INTERIOR Y OTRO EXTERIOR, AMBOS SE FIJAN POR UN LADO Y DELIMITAN UN ESPACIO HUECO CIRCULAR, QUE ALEJADO DE LA FIJACION DE AMBAS TUBERIAS SE OBTURAN POR MEDIO DE UNA JUNTA CIRCULAR. ESTA ESTA FORMADA POR UN ANILLO DESPLAZABLE (3); EN LA ZONA DEL MISMO (3) SOLO ESTA CONSTRUIDO CILINDRICAMENTE UNO DE LOS TUBOS (6), EL OTRO EN LA PROLONGACION ASUME UNA FORMA CONICA, LEJOS DE LA FIJACION (4).
