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 rupture disc apparatus comprises a rupture disc holding cartridge and a fixed receptacle for receiving the cartridge. The receptacle is positioned in a vent so as to communicate on opposite sides thereof with the vent. The cartridge is removable from and replaceable into the receptacle when no pressure exists within the vent so as to position the rupture disc to block passage of fluid through the vent when the disc is unruptured. A first of the receptacle or cartridge includes circumferential seating rings on opposite sides thereof and the other of the receptacle or cartridge includes seats for the rings. The seats and rings are positioned adjacent to the vent. The rings are urged into locking position in the seats by pressure from within the shaft and are manually removable when substantially atmospheric pressure exists within the vent.

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. Various aperture patterns in the center of the rupture body are provided to facilitate predictable opening. The slits are divided into segments connected by bridges to help prevent the slits from separating and the sealing membrane from creeping through the slits prior to rupture. Protective strips adjacent the slits are positioned between the rupture body and the sealing membrane to reduce creep of the membrane through the slits prior to rupture. A vacuum support grid is provided for the panel to support the sealing membrane against a vacuum acting thereon opposite the rupture body.

摘要： A rupture disc system comprises a rupture disc including a dome portion and a flange portion interconnected by a transition region and a mounting mechanism for mounting the rupture disc by the flange portion thereof in a pressure relieving vent. The rupture disc includes a thickness reducing groove at least partially circumferentially surrounding the dome portion and located in the transition region thereof. The rupture disc is of the reverse buckling type and the groove does not completely surround the dome portion so as to define a tab or hinge within that part of the transition region which is ungrooved or not as deeply grooved as a remainder of the transition region. The system includes a support structure for the disc which supports the transition region except in a sector adjacent the dome portion where initial failure is desired. The location of the unsupported sector is approximately centered relative to the tab or hinge. In addition, the disc support structure preferably comprises a downstream ring member having an arcuate projection which extends into the vent. The arcuate projection is located so as to be relatively close to and so as to align with the tab or hinge such that the dome portion wraps about the projection when reverse buckling and rupture occurs.
摘要翻译：破裂盘系统包括破裂盘，其包括圆顶部分和通过过渡区域互连的凸缘部分和用于通过其凸缘部分将泄漏盘安装在减压通气口中的安装机构。破裂盘包括至少部分地围绕圆顶部分并位于其过渡区域中的厚度减小槽。破裂盘具有相反的弯曲类型，并且凹槽不完全围绕圆顶部分，以便在过渡区域的该部分内限定突出部或铰链，该过渡区域未被过渡或不像过渡区域的其余部分那样深沟槽。该系统包括用于盘的支撑结构，其支撑过渡区域，除了邻近需要初始故障的圆顶部分的扇区之外。未支撑扇区的位置大致相对于接头或铰链居中。此外，盘支撑结构优选地包括具有延伸到通气孔中的弓形突起的下游环构件。弧形突起被定位成相对靠近并且与突片或铰链对准，使得当发生反向弯曲和破裂时，圆顶部分围绕突起卷绕。
