Abstract: An improved rupture disk assembly and methods and apparatuses for forming a rupture disk are disclosed. The rupture disk assembly includes a rupture disk (44) that has a flange connected to a dome-shaped rupturable portion by a transition area and is sealed between a pair of support members (30, 32). The rupturable portion may include an indentation positioned at the apex of the dome and a score line having a first and a second end. A safety member (50) that has a hinge (52) including a knuckle and a tongue (54) is positioned between the rupture disk and an outlet support member. The knuckle extends downwardly into the dome and extends laterally across the dome to a point that is inside the area circumscribed by the score line or inside the area circumscribed by an arc connecting the two ends of the score line. The present invention is also directed to an apparatus and method for consistently, accurately, and repeatably forming a structural apex formation in a rupture disk before the formation of the rupture disk dome, during the formation of the rupture disk dome, and after the formation of the rupture disk dome.

Abstract translation: 公开了一种改进的破裂盘组件和用于形成破裂盘的方法和装置。 破裂盘组件包括破裂盘（44），其具有通过过渡区域连接到圆顶形可破裂部分并且被密封在一对支撑构件（30,32）之间的凸缘。 可破裂部分可以包括定位在圆顶顶点处的凹陷和具有第一和第二端的刻痕线。 具有铰链（52）的安全构件（50）包括转向节和舌部（54），位于破裂盘和出口支撑构件之间。 转向节向下延伸到圆顶中，横向延伸穿过穹顶到位于由刻划线限定的区域内部或由连接刻痕线的两端的弧限定的区域内的点。 本发明还涉及一种用于在形成破裂盘形圆顶之前，在形成破裂盘形圆顶之前，在形成破裂盘形圆顶之前以及在形成破裂盘形圆顶之后，在破裂盘中一贯地，精确地和可重复地形成结构顶点形成的装置和方法 破裂盘圆顶。
