摘要： Valves for controlling the release of a substance, include a housing having an inlet for connection to a source of the substance, an outlet, and a passage extending therebetween. The passage is enclosed by a ceramic disc and means are provided to apply an electrical pulse to the disc to break the disc and so connect the inlet to the outlet. The methods include containing the substance in a container, connecting the container to a valve; and applying an electrical pulse to the disc to break the disc and connect the inlet to the outlet. The valves and methods are particularly suited, but not limited, to the control of substances such as pressurised fire extinguishing media.

摘要： A multi-piece crucible for high temperature applications comprises a tubular side wall member having a lip on the inside surface and a bottom member or members forming a container for containing a melt of a material during a high temperature melt-casting operations. The multi-piece design prevents cracking of the crucible or leakage of the melt from the crucible during the melt-casting operation. The lip of the tubular member supports the bottom member. The contacting surfaces where the lip of the tubular side wall member contacts the bottom member of the multi-piece crucible contains a ceramic sealing material. The ceramic sealing material forms a seal sufficient to prevent the melt of the material from leaking out of the multi-piece crucible during the melt-casting process. The multi-piece crucible is made of a material which is chemically inert to the melt and has structural integrity at the melting point temperature of the melt, or of a material coated with such a material.

摘要： A multiple-dome, scored rupture disc presents opposing first and second disc faces, and is provided with a circular, central region and a flat annular flange surrounding the central region. An arcuate line of weakness is formed in the disc circumscribing the central area except for a portion of the circumference of the central area defining a hinge about which the central region pivots upon rupture. The central region is divided by a diametrical ridge into two side-by-side semicircular halves within which the disc is bulged to form a plurality of separate concavo-convex bulges in the body.

摘要： A bursting disc assembly comprises a generally tubular body provided with an external screw thread and, at one end of the body, a counterbore which forms an annular seat within the body to accommodate at least the peripheral regions of a preferably flat bursting disc; a bursting disc located on the seat and a plug with a longitudinal bore pushed into and a tight fit within the counterbore so as to hold the bursting disc in place, the plug being prevented from rotating with respect to the body by knurls which bite into the walls of the counterbore. In use, the assembly is screwed into the housing of a pressure relief device so that the free end of the plug bears against and forms a fluid-tight seal with an opening in the base of the housing and at the same time, the other end of the plug compresses the bursting disc against the seat so as to form fluid-tight seals between plug, bursting disc and seat.

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 rupturable pressure relief apparatus which is non-fragmenting and which is particularly suitable for liquid and low pressure gas service. The apparatus includes an annular rupture disk having an annular flange portion connected to a concave-convex portion by a circular transition connection. The concave-convex portion includes a groove in a side thereof creating a substantially circular line of weakness therein and at least one concave-convex hinge reinforcing member is attached to a side of the concave-convex portion of the rupture disk. The hinge reinforcing member is positioned and is of a shape whereby upon rupture of the rupture disk, the concave-convex portion tears along the line of weakness created by the groove and bends about an integral untorn portion corresponding with the hinge reinforcing member.

摘要： A monitor system for sensing the failure of a rupture disc and activating an alarm in response to such a failure. The system also senses potential failure of a rupture disc. The system includes a failsafe signal carrying loop which is broken when the rupture disc fails, thereby interrupting the signal. The system also includes a signal sensor which recognizes a signal interruption or substantial modification in the signal and initiates and cooperates with an alarm device to provide notice to an operator or a safety device that the rupture disc has failed.

摘要： A pressure release assembly provides controlled depressurization of a sea gas-containing vessel, such as a xenon-filled arc lamp, when the temperature of the gas in the vessel reaches a value corresponding to a selected pressure. The assembly comprises a thin metallic rupture plate that hermetically seals an aperture in a wall of the vessel, and a back-up disc that is supported adjacent the other surface of the rupture plate. The back-up disc reinforces the rupture plate so as to prevent bursting of the rupture plate at pressures below the selected pressure. The back-up disc is made of a material that loses its tensile strength at the temperature corresponding to the selected pressure, whereby the weakening of the back-up disc at the selected pressure causes the rupture plate to burst. The back-up plate may be made of a eutectic alloy that melts at the temperature corresponding to the selected pressure.
