Abstract

Un tapon de tubería que comprende cabezales de obturacion conectados en forma de pivote, cada cabezal de obturacion con un elemento sellador, que funcionan en combinacion para llevar a cabo la purga y doble bloqueo de una tubería. El primer elemento sellador evita el flujo del producto en la tubería y el segundo elemento sellador captura las pérdidas que pasen el primer elemento sellador y hace que la pérdida salga a través del adaptador de calce. Una almohadilla de estabilizacion, conectada a una brida sobre una parte frontal de cada cabezal de obturacion, evita la deformacion de los elementos selladores. Un brazo de pivote cargado por resorte, conectado al segundo cabezal de obturacion permite que la abrazadera que conecta los dos cabezales de obturacion roten en forma libre. Una proyeccion conica elevada hacia el exterior sobre el brazo de pivote, junto con una rueda guía conectada al primer cabezal de obturacion evita que las abrazaderas y los cabezales de obturacion queden entrampados durante su instalacion en o remocion de la tubería.
