Abstract: There is provided a valve for controlling the release of fire suppressant from a pressurized container, said valve comprising a diaphragm configured to perforate upon action of a shockwave directed onto the surface of said diaphragm, a pyrotechnic charge arranged and adapted to combust to produce combustion products that form a shockwave directed onto the surface of said diaphragm, and a device encasing said pyrotechnic charge. The device comprises a hollow, elongate channel located over said pyrotechnic charge and directed at the center of said diaphragm so as to focus or direct said combustion products onto the center of said diaphragm. The elongate channel has a length that is at least 1.5 times its smallest width.

Abstract: A frangible plug for use in a valve mechanism, the frangible plug including a first section having a first end and an opposing second section having a second end and a cylindrical sidewall extending between the first and second ends. Also including means for applying a force on the cylindrical sidewall of the frangible plug such that the first section fractures from the opposing second section, and wherein the means for applying a force on said cylindrical sidewall extends circumferentially around the outer circumference of the sidewall.

Abstract: There is provided a valve for controlling the release of fire suppressant from a pressurised container, said valve comprising a diaphragm configured to perforate upon action of a shockwave directed onto the surface of said diaphragm, a pyrotechnic charge arranged and adapted to combust to produce combustion products that form a shockwave directed onto the surface of said diaphragm, and a device encasing said pyrotechnic charge. The device comprises a hollow, elongate channel located over said pyrotechnic charge and directed at the centre of said diaphragm so as to focus or direct said combustion products onto the centre of said diaphragm. The elongate channel has a length that is at least 1.5 times its smallest width.
Abstract translation: 提供了一种用于控制来自加压容器的防火剂释放的阀，所述阀包括隔膜，其构造成在引导到所述隔膜表面上的冲击波作用下穿孔，布置并适于燃烧以产生燃烧产物的烟火电荷 其形成指向所述隔膜的表面的冲击波，以及包围所述烟火充电的装置。 该装置包括位于所述烟火装料上方的中空的细长通道，并且指向所述隔膜的中心，以将所述燃烧产物聚焦或引导到所述隔膜的中心。 细长通道的长度至少为其最小宽度的1.5倍。
