摘　　要：详细分析了3D条阀的设计思想。应用典型的水-空气冷模实验系统对3D条阀、STV条阀和F1型浮阀3种条阀进行了对比实验研究,测定了多种气液负荷下3种浮阀塔板的板压降、雾沫夹带和漏液量等流体力学性能,利用氧解吸法测定了3种浮阀塔板的传质效率。实验结果表明,在相同条件下,3D条阀各方面的性能均比上一代产品STV条阀以及F1型浮阀优良,板效率提高,在工业应用范围内,板压降最小,雾沫夹带与泄漏量比STV条阀小而与F1基本相当,是一种综合性能优良的高效条阀。The designing philosophy of 3D strip valve is analyzed in detail. In an experimental rectangular column of 1 000 min× 350 mm,comparision experiments of 3D strip valve with STV strip valve and F1 valve were performed by employing a typical model experimental system of water-air. The hydraulic properties, such as tray pressure drop, entrainment rate, and weeping rate were measured, and the mass transfer efficiency was determined through the method of oxygen-absorptions. The results demonstrated that under the same conditions, the comprehensive performance of 3D strip valve was better than that of STV strip valve and F1 type of valve. The Way efficiency of 3D strip valves was the highest, while the tray pressure drop was the lowest in the scope of industrial use, and the entrainment rate and weeping rate were lower than that of STV strip valve and almost the same with F1 type. It＇s proven that 3D strip valve was a better valve in terms of comprehensive technology.
