摘要： A safety pressure relief device is provided for the venting of fluid pressure between first and second pressure zones. The relief device includes a first rupture disk having a flexible sealing membrane located on one side thereof, and a knife means located on the other side of the first rupture disk. The first rupture disk includes a plurality of arcuate slots circumscribing a substantially circular blowout portion. The knife means includes a circular cutting blade located radially inward of the arcuate slots. Upon rupture of the first rupture disk, due to excess pressure in the second pressure zone, the substantially circular blowout portion passes through a circular opening in the knife means, allowing the flexible sealing membrane to contact the cutting blade and be severed thereby. Alternative embodiments add a second rupture disk to relieve excess fluid pressure from the first pressure zone to the second pressure zone.

摘要： The present invention relates to a safety pressure relief apparatus comprised of a reverse buckling rupture disk having a concave-convex portion connected to an annular flat flange portion by a curved transition connection and a support member having an annular flat flange portion for engaging the annular flat flange portion of the rupture disk and for supporting the transition connection thereof. The support member includes a partially circular cutting edge positioned interiorly of the transition connection and forming, in conjunction with a non-cutting interior edge, an opening in the support member so that when the concave-convex portion of the rupture disk reverses itself, the cutting edge partially severs the disk whereby a portion thereof bends about an unsevered hinge portion and passes through the opening in the support member. The hinge portion of the rupture disk is supported by the non-cutting interior edge of the support member. An improved serrated cutting edge is included having rounded notches between adjacent teeth thereby providing a cutting edge with fewer stronger teeth extending a shorter distance so that the available flow area through the opening in the support member is increased.
摘要翻译： 本发明涉及一种安全压力释放装置，该装置包括一个反向弯曲破裂盘，它具有通过弯曲过渡连接部连接到环形平坦凸缘部分上的凹凸部分，以及具有用于接合环形平面的环形平坦凸缘部分的支撑部件 并且用于支撑其过渡连接。 支撑构件包括位于过渡连接件内部的部分圆形切割刃，并且与非切割内部边缘结合形成支撑构件中的开口，使得当破裂盘的凹凸部分自身反转时， 切削刃部分地切除盘，由此其一部分围绕未切割的铰链部分弯曲并穿过支撑构件中的开口。 破裂盘的铰链部分由支撑构件的非切割内部边缘支撑。 包括在相邻齿之间具有圆形凹口的改进的锯齿形切割刃，从而提供切割边缘，其中较少的较强的齿延伸较短的距离，使得通过支撑构件中的开口的可用流动面积增加。

摘要： A safety pressure relief device including a rupture disk having a concave-convex portion and a radially outer flange portion joined by a curved transition connection. An improved knife means is located adjacent the concave side of said rupture disk, said knife means including a radially outer flange portion which supports said curved transition connection. A substantially circular inner opening is disposed in said knife means. Said knife means includes first and second spaced cutting means projecting radially inward into said opening and inclined towards said concave portion of said rupture disk. Said knife means further includes first and second arcuate non-cutting portions each partially defining said inner opening. The first cutting means is located between said first and second non-cutting portions so that upon reversal of said rupture disk said first and second cutting means will puncture said rupture disk without severing a portion of the disk therefrom.
