Abstract
PURPOSE: To prevent fatigue breakdown of a rupture disc by arranging a rupture disc having a small hole at the center and another rupture disc on the back surface of the former rupture disc through a buffer chamber.
CONSTITUTION: Normal operation pressure P1 becomes nearly equal to the pressure P2 of a buffer chamber C, for a pipe D and the buffer chamber C are connected through the small hole E of a rupture disc A. The pressure which the rupture disc A receives becomes nearly O. At this time, a rupture disc B receives the pressure P1-P0≈P2-P0, or the pressure in the system P1≈P2. When this pressure P1 varies by ΔP1, and ΔP1 is smaller than the pressure P1, the rupture disc A receives the pressure change of only ±ΔP1. The rupture disc B receives pressure change smaller than in case of A, due to the orifice effect of the small hole E. Thus, the magnitude of repeating load can be ignored, and fatigue breakdown of rupture disc can be prevented.
