Abstract
以典型DN125通海阀为对象，在通海阀主要结构尺寸不变的情况下对其局部部位进行改进优化，分别提出了四种优化方案，并对优化方案的声学特性进行分析。分析结果表明，其中方案二和方案四的流体噪声声功率级均大幅下降，且工艺性良好。 By using a typical seacock for DN125 as the object, under the condition of invariable in the main structure size, we optimized the local area, put forward four kinds of optimization schemes re-spectively, and analyzed the acoustic characteristics of the optimized schemes. The results show that the sound power levels of fluid noise significantly decrease in the second and fourth schemes, and the manufacturability is feasible.
DN125低噪声通海阀结构初步设计及其声学特性分析 The Preliminary Design and Acoustic Characteristics Analysis of the Low Noise Seacock for DN125
以典型DN125通海阀为对象，在通海阀主要结构尺寸不变的情况下对其局部部位进行改进优化，分别提出了四种优化方案，并对优化方案的声学特性进行分析。分析结果表明，其中方案二和方案四的流体噪声声功率级均大幅下降，且工艺性良好。 By using a typical seacock for DN125 as the object, under the condition of invariable in the main structure size, we optimized the local area, put forward four kinds of optimization schemes re-spectively, and analyzed the acoustic characteristics of the optimized schemes. The results show that the sound power levels of fluid noise significantly decrease in the second and fourth schemes, and the manufacturability is feasible.
