Test system for assessment of pressure waves and dynamic behaviors under rupture conditions of piping line

摘要

The present invention relates to the analysis of impact and dynamic behavior at the time of pipe rupture to evaluate the effect of the steam jet emitted from the corresponding rupture zone on the surrounding structure and equipment when piping for high energy fluid transportation installed in a nuclear power plant or a plant facility A simulation system for analyzing impact and dynamic behavior at the time of pipe rupture according to the present invention includes a presser for raising the internal pressure to a set value, A fluid delivery pipe for delivering a fluid for raising the pressure in the pressurizer from the inside of the pressurizer; a fluid injecting unit coupled to the other end in the longitudinal direction of the fluid delivery pipe to inject fluid in the fluid delivery pipe; When the direction in which the fluid in the fluid conveyance pipe is injected is set forward, A fluid impinging portion provided in front of the fluid ejecting portion and configured to collide with a fluid ejected through the fluid ejecting portion; and a pressure sensor installed in the fluid impinging portion, And a load measuring unit for measuring a load at the time of collision with the fluid impact portion of the fluid injected through the load.;
