Measuring Result of Self-induced Vibration in Pipeline System using Automatic Pressure Regulator and Constant Flow Valve and the Control Measure

Abstract: ; Self − induced vibration is possibly caused by the semi − closed pipeline combining the automatic pressure regulator with the automatic constan 田 ow valve , Thus , a test was conducted on the site to analyze the generation of the coupled osciUation between the automatic pressure regulator and the direct − acting constant fiow valve . Fumher , the investigatiou was conducted j 皿 order to show the function of the constant flow valve , obtain self −excited oscillation , and to study the control measure . Conseq… Show more

“…The authors investigated an example of a large pressure variation continuing for a long time, which was linked with an opening and shutting operation of division works in the low-pressure system. In this system, improved pressure-reducing valves and direct acting constant flow valves are used, which are shown in Figure 1 (Inagaki et al, 2007). The field test was conducted in a gravity-flow pipeline, which obtains water from a water reservoir, and the total length of the pipeline is approximately 1.7 km.…”
