    • A one-time-use pressure-actuated conduit closure is provided, to selectively withstand fluid pressure from one side of the device until the closure is removed remotely, the closure device being a frangible dome designed to withstand fluid pressures from one side but to rupture upon application of higher pressure on its other side, which provides a mechanism to isolate downhole fluid under (high) pressures in part of a well during operations for a period of time selected by an operator, and then to remove the isolation by breaking the rupture dome remotely by application of extra fluid pressure or other forces from surface. The frangible dome has features in at least one surface to guide and control its breakage to provide controlled shard sizes and shapes and a predictable opening for minimal obstruction of the conduit when broken away.

    • A rupture disk is provided for relieving pressure between the interior of a battery box and the exterior of the battery box, the box having an outlet opening. The apparatus includes a first layer that provides a gasket which abuts the battery box, the gasket having a central opening which aligns with the battery box opening. A second layer is in the form of a reverse buckling disk having a disk flange, a domed portion and a weakened portion on the dome that defines a disk burst pressure, the second layer having concave and convex sides. A third layer that is an outlet ring that sandwiches the second layer in between the first and the third layer layers, the outlet ring having a central opening surrounded by an edge. A plurality of teeth on the third layer extend from said edge inwardly a distance. A plurality of tabs are provided on the first and third layers, said tabs including circumferentially spaced apart tabs on each of said first and third layers, each tab having a tab opening, said tabs generally aligning so that a fastener can be passed through the tab openings of the first layer and the third layer. The third layer is attached to the second layer which is a metal disk by means of spot weld around the disk flange and the first layer attached to the metal disk by means of an adhesive thus forming a rupture disk assembly. The fasteners affix this rupture disk assembly to the box. The second layer is generally circular and surrounded by the fasteners. The teeth are positioned on the concave side of the second layer. In a preferred embodiment, the teeth do not extend so far inwardly that they extend inwardly beyond the weakened portion or score. From any radial line extending from the center of the layers, the weakened portion is reached before any tooth, the teeth thus being spaced radially a distance equal to or greater than the weakened portion or score.
    • 提供了一种用于缓解电池盒内部和电池盒外部之间的压力的破裂盘,该盒具有出口。 该装置包括提供与电池盒邻接的垫圈的第一层,垫圈具有与电池盒开口对准的中心开口。 第二层呈反向弯曲盘的形式,其具有圆盘凸缘,圆顶部分和圆顶上的限定盘突发压力的弱化部分,第二层具有凹凸面。 第三层,其是在第一和第三层之间夹住第二层的出口环,出口环具有由边缘包围的中心开口。 第三层上的多个齿从所述边缘向内延伸一定距离。 多个凸片设置在第一和第三层上,所述凸片包括在每个所述第一和第三层上的周向间隔开的凸片,每个凸片具有凸片开口,所述凸片大致对齐,使得紧固件可以穿过凸片 第一层和第三层的开口。 第三层通过围绕盘凸缘的点焊附接到第二层,第二层通过粘合剂附接到金属盘的第一层,从而形成破裂盘组件。 紧固件将该破裂盘组件固定在箱体上。 第二层通常为圆形并被紧固件包围。 齿定位在第二层的凹面上。 在一个优选实施例中,齿不会向内延伸至向内延伸超过弱化部分或刻痕。 从层的中心延伸的任何径向线,在任何齿之前到达弱化部分,因此齿在径向间隔开等于或大于弱化部分或分数的距离。

    • A multiple-domed, scored rupture disc (28) having a non-apertured disc body (62) provided with separate, side-by-side, semi-circular concavo-convex bulges (76) and an arcuate line of weakness (68) circumscribing the bulges is provided with a diametrical ridge (74) extending across and serving as a divider between the bulged areas of the disc body. The distance between the outer margin of the ridge and a plane through the annular planar section of the disc body is from about 0.3 % to about 3 % of the diameter of the bulged area to increase the rigidity of the divider ridge. The greater rigidity of the divider ridge decreases the burst pressure of the disc.
    • 具有设置有分开的并排的半圆形凹凸凸起(76)和弧形的弱线(68)的非圆形的圆盘体(62)的多圆顶,刻痕的破裂盘(28) 在凸缘部分设置有沿着盘体的凸出区域延伸并用作分隔件的直径脊(74)。 脊的外边缘与通过盘体的环形平面部分的平面之间的距离为凸起面积的直径的大约0.3%至大约3%,以增加分隔脊的刚性。 分离器脊的较大的刚度降低了盘的爆裂压力。
