摘要
目前,我国正在开展超大输量天然气管道的研究工作,而快开盲板一直是制约国内油气管道关键设备国产化的"瓶颈"之一。12.6 MPa、DN1 550快开盲板因结构复杂、压力高、直径大、温度低以及承受冲击载荷大等原因,而使得其研制与应用面临较多的技术难题。以新疆北天山气侯环境以及直径1 422 mm、压力12 MPa的天然气管道为基本条件,采用有限元分析与应力测试验证方法,通过整机低温性能试验、结构与材料优化、发明缓冲装置等创新设计措施,研制出2台12.6 MPa、DN1 550安全自锁型快开盲板,并通过性能测试与工程应用,验证了产品的可靠性,为超大输量管道建设提供了技术储备。
In China, great efforts are devoted to development of pipelines with super-high transmission capacities. However, the quick-opening closure has been the bottleneck of restricting the localization of key pipelines equipment in China. There are many technical challenges on the development and application of the 12.6 MPa/DN1 550 quick-opening closure due to its complex structure, higher pressure, large diameter, low temperature and significant impact loading conditions. Taking natural gas pipelines with the diameter of 1 422 mm and the pressure of 12 MPa in the North Tianshan Mountain in Xinjiang as the example, through stress testing and finite element analysis, two 12.6 MPa/DN1 550 safety self-locking type quick-opening closures have been developed on the basis of structure modification, material optimization, development of cushioning device and overall low-temperature performance test. Reliability of these products has been verified through performance tests and engineering applications. The new equipment provides technical reserves for pipelines with super- high transmission capacities. （8 Figures, 11 References）
