Title:
逆座屈サニタリーラプチャディスク組立物
Document Type and Number:
Japanese Patent JP4741475
Kind Code:
B2
Abstract:
A metal reverse buckling sanitary rupture disc is provided having a central bulged section in which the convex surface of the bulged section is relatively smooth and of substantially uninterrupted configuration. A small segment region of the central bulged section is strain hardened by plastic deformation causing the segment region to have greater residual stress than the remainder of the central bulged section. When the disc is subjected to an overpressure condition against the convex surface of the bulged section sufficient to effect reversal of the bulged section, such reversal commences at the higher residual stress segment region of the bulged section.
