摘要： A low pressure venting panel acts to safely vent a pressure vessel, such as a bag house, from overpressure conditions. The venting panel is particularly responsive and predictable at low pressures. The panel includes a thin rupture body with a central group of apertures and slit lines emanating from the apertures. A thin sealing membrane is bonded to one surface of the rupture body at least in the area of the slits. The characteristics of the sealing membrane enable the membrane to resist expansion in the area of the slits when pressure is applied to the rupture body, thereby resisting rupture of the membrane up to the design rupture limit of the venting panel.

摘要： A safe pressure relief assembly of the rupture disc type guards against pressure differentials beyond a predetermined range extending both above and below zero and includes a positive relief disc which is perforated to permit negative flow without rupturing, a sealing disc normally blocking the perforations, a cutting member positioned in spaced relation to the sealing disc and extending a substantial transverse distance thereacross and a sealing disc support member having a stay arrangement projecting into negative supporting engagement with the sealing disc, the stay arrangement having a resistance to collapse sufficient to retain the sealing disc out of contact with the cutting member only up to a predetermined negative pressure. The subcombination of sealing disc, stay arrangement and cutting member is separately useful, especially as a very low pressure relief device.

摘要： A safety pressure relief assembly of the rupture disc type guards against pressure differentials, beyond a predetermined range in a vent system, and includes a relief disc perforated to permit reverse flow without rupture, a sealing disc positioned adjacent the relief disc and blocking positive flow through the perforations, a support member with a stay structure positioned to support the sealing disc nested within the relief disc, and a cutting member positioned to cut the sealing disc at a predetermined vacuum within the vent system. The relief disc has a concave surface and a convex surface. When a predetermined vacuum pressure differential is applied to the assembly, the sealing disc and the support structure are inverted to project away from the relief disc. During the inversion, the support structure is recessed between cutting blades of the cutting member and the sealing disc impacts the cutting blades and is cut thereby into a pattern having petals and a silhouette portion in the shape of the support structure. As fluid under pressure flows through the rupture disc assembly, the silhouette portion of the sealing disc is supported by the support structure and is located between the cutting blades. After cutting by the blades, the petal portions are no longer supported by the support structure and fold out of the way of the fluid to open channels or passageways through the rupture disc assembly and permit rapid equilibration of pressure between opposite sides of the system without loose portions of the assembly being formed.
摘要翻译：破裂盘型的安全压力释放组件防止压力差超过排气系统中的预定范围，并且包括穿孔以允许反向流动而不破裂的浮雕盘，邻近浮雕盘定位的密封盘并阻止正向流动穿孔，具有支撑结构的支撑构件，其被定位成支撑嵌套在浮雕盘内的密封盘;以及切割构件，其定位成在通气系统内以预定的真空切割密封盘。浮雕盘具有凹面和凸面。当将预定的真空压力差施加到组件时，密封盘和支撑结构被倒置以远离浮雕盘突出。在倒转期间，支撑结构在切割构件的切割刀片之间凹陷并且密封盘冲击切割刀片，并且被切割成具有支撑结构形状的花瓣和轮廓部分的图案。当压力下的流体流过破裂盘组件时，密封盘的轮廓部分由支撑结构支撑并位于切割刀片之间。在刀片切割之后，花瓣部分不再被支撑结构支撑并且折叠成流体的方式以打开通过破裂盘组件的通道或通路，并允许系统的相对侧之间的压力的快速平衡而不松动组件的部分形成。

摘要： A safety pressure relief device of the reverse buckling type includes a puncturing element and a rupture disc having a groove or score line formed in the flange portion of the disc. The score line does not materially affect the rated pressure of the device during normal operation, and functions as a backup safety feature by providing a line of weakness along which the disc will tear if the pressure relief device is accidentally placed in a backward or reversed orientation with respect to the process, and/or if the cutting blades are inadvertently omitted from the rupture disc assembly.

摘要： A reverse buckling disc arrangement for direct mounting eliminates separate inlet and outlet seating rings for the disc flange. Centering ring units on both sides of the disc have flanges doubling as the seating rings. The centering ring projecting toward the higher pressure supports a screen for protecting the disc dome while permitting necessary flow-through.
