Post-earthquake fire is one of the major hazards faced by a city after the devastating earthquake. For the city gas pipeline network, it is especially important to establish an earthquake emergency handling system. Emergency handling systems for urban gas pipe network in Japan, the United States and China＇s Taiwan region have reduced the effectiveness of the earthquake fire. With the growing popularity of the gas pipeline, it is also very important to apply the earthquake emergency handling facilities in China that is also an earthquake prone zone. In this article, the Northridge2000, a small earthquake gas valves made in U. S. A, and a gas pipeline earthquake emergency handling device designed by us are applied, respectively, on small diameter gas pipeline of the four houses and a large diameter gas pipeline in Kunming to demonstrate earthquake emergency handling of gas pipeline. Some artificial triggering tests have been carried out and showed that the response of the emergency handling device is consistent with the expectation, but the inspection of the actual earthquake is needed to confirm the performance of devices. This article describes the design and demonstration application of a gas pipeline earthquake emergency handling, and discusses some problems needed to be resolved in China to carry out related work.[著者文摘]
