    摘要: A rupture disk (200) having a line of weakness (235) is disclosed. In one embodiment, a frustum-shaped rupture disk has a shear-scored line of weakness located in one or more of a central truncated portion (220), an angled frustum portion (230), a flange portion (210), and in the areas of transition between a flange portion and an angled frustum portion, and between an angled frustum portion and a central truncated portion. In another embodiment, a frustum-shaped rupture disk has an angled frustum portion, with a line of weakness in the angled frustum portion. A stiffening member may be provided to stiffen a central truncated portion of a frustum-shaped rupture disk.
