摘要： An improved composite rupture disk assembly adapted to be supported between inlet and outlet supporting members is provided. The assembly is comprised of a resilient sealing member and a rupture member having a plurality of elongated openigs formed therein which extend outwardly from a central portion thereof. At least one rupture pressure determining score is formed in the rupture member connecting the inner ends of two or more of the elongated openings so that rupture of the composite assembly occurs when pressure is exerted on the sealing member and transmitted to the rupture member at a level equal to or exceeding the rupture pressure of the rupture member.

摘要： A pressure relief safety device useful for operation in a low pressure range. The device utilizes a non-metallic relatively thin air-impermeable membrane extending across a housing, the latter of which is in communication with a system operable under pressure. When the pressure in the system increases beyond a predetermined threshold pressure level, the membrane will expand and contact a rupturable member which will rupture the membrane. In this way relief for the excess pressure conditions is obtained. The rupturable member is adjustably located with respect to the membrane to thereby adjust and vary the predetermined threshold pressure level.
摘要翻译：用于在低压范围内运行的减压安全装置。该装置使用延伸穿过壳体的非金属相对薄的不透气膜，后者与外壳在与压力下可操作的系统连通。当系统中的压力增加超过预定的阈值压力水平时，膜将膨胀并接触可破裂的构件，其将使膜破裂。以这种方式获得对过压条件的缓解。可破裂构件相对于膜可调节地定位，从而调节和改变预定阈值压力水平。

摘要： An aircraft comprises an overpressure valve, the overpressure valve comprising a sealing member which is moveable, in response to a first pressure differential across the valve, between a closed position and an open position. The overpressure valve further comprises a frangible portion, for example a carbon or sheet metal disc. The frangible portion is arranged to fail in response to a second pressure differential across the valve, the second pressure differential being more than the first pressure differential. Thus the valve is still able to relieve pressure when the sealing member is jammed (due to ice for example). It is therefore relatively safe. The valve may be in the surge tank of a fuel tank system.
摘要翻译：一种飞机包括一个超压阀，该超压阀包括一个密封件，该密封件响应于阀门上的第一压力差在可关闭位置和打开位置之间移动。超压阀还包括易碎部分，例如碳或钣金盘。易碎部分被布置成响应于跨越阀的第二压差而失效，第二压力差大于第一压力差。因此，当密封构件卡住（例如由于冰）时，阀仍然能够释放压力。因此，这是比较安全的。阀可以在燃料箱系统的缓冲罐中。

摘要： A two directional rupture disc assembly is provided which serves in a fluid reactor system as a safety relief valve when a critical condition, such as predetermined pressure positive or negative, is encountered. That is, the rupture disc assembly hereof is operatively coupled to a reactor vessel and allows fluid flow in one direction when one reactor system condition is encountered and allows fluid flow in an opposite direction when another reactor system condition is encountered. Thus, under normal conditions, the reactor system operates in a certain pressure range with the assembly hereof in flow blocking disposition, but if a reactor condition outside of the normal operating range is encountered, the assembly ruptures to permit fluid flow in the appropriate direction. Preferably, the rupture disc assembly includes a pair of flat rupture discs and an imperforate membrane between the two discs. Each disc includes an innermost and outermost C-shaped pattern formed by a plurality of serially arranged slots through the respective disc. Advantageously, the discs and membrane are mounted and the patterns manufactured such that the discs rupture adjacent the outermost pattern when one condition is encountered and the discs rupture adjacent the innermost pattern when another condition is encountered.
摘要翻译：提供了两个方向的破裂盘组件，其在遇到诸如预定压力正或负的临界条件时在流体反应器系统中用作安全泄压阀。也就是说，其中的破裂盘组件可操作地耦合到反应器容器，并且当遇到一个反应器系统条件时允许流体在一个方向上流动，并且当遇到另一个反应器系统条件时允许流体沿相反的方向流动。因此，在正常条件下，反应器系统在一定的压力范围内工作，其组件本身处于流动阻塞状态，但是如果遇到正常工作范围之外的反应器状态，则组件破裂以允许流体沿适当的方向流动。优选地，破裂盘组件包括一对平坦的破裂盘和两个盘之间的无孔膜。每个盘包括通过相应盘的多个串联布置的槽形成的最内侧和最外侧的C形图案。有利地，安装盘和膜，并且制造图案，使得当遇到一个条件时，盘破裂在最外面的图案附近，并且当遇到另一个条件时，盘破裂在最内层图案附近。

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 invention provides a method, apparatus and system capable of releasing excess pressure above a predetermined point by opening and closing repeatedly through the actuation of a moving element. The said moving element is capable of bursting in case of a rise in pressure above a secondary predetermined point. The invention hence provides a way to regulate the pressure in two different manners depending on the severity of the overpressure.
