120000m～3/h等级空分设备配套阀门选型

针对120 000 m3/h特大型空分设备阀门选型的设计,通过分析阀门工作参数和内部结构,在充分考虑空分安全性前提下,选择满足工艺条件和控制要求的阀门。介绍了特大型空分设备上重要阀门在选型上不同于常规空分设计的一些改进措施,科学合理地选择适用的阀门,使阀门材质、结构及功能应用适合于整套空分工况的需要,为空分设备提供了安全可靠的技术保证,同时也降低了建造特大型空分设备的建设成本,为特大等级空分设备全面合理选择阀门提供有利的参考经验。

SELECTION OF COROLLARY VALVES FOR 120 000 m～3/h GRADE AIR SEPARATION PLANT

In view of the 120 000 m3/h valve type selection design of very large air separation equipment,through the analysis of the valve working parameters and internal structure,under the precondition of fully considering the air separation safety,the valve is chosen to meet the requirement of process conditions and control. Very large air separation devices are introduced important valve on the selection of different some improving measures of the conventional air separation design. The applicable valve is selected to make the material of the valve,the structure and function of application is suitable for the need of the whole air separation condition. A reliable technical guarantee is provided. The cost of construction of super large air separation equipment is reduced. The beneficial reference experience is exhibit for selection valve of large scale air separation device.
