摘要

针对流体诱发调节阀振动和噪声而影响汽轮机安全、稳定运行的问题

结合实验和数值模拟研究了阀内流型分布及流型与噪声、振动的关系。研究表明:在中小升程下调节阀内存在2种流型

其中附阀座流相对于冲击射流是一种更加稳定且噪声较小的流型; 不同压比调节方式下

即使同一工况也会出现这2种流型; 连续改变压比会出现一种声音突变现象

该现象由附阀座流和冲击射流的转变所致; 利用声音突变可以确定调节阀在中小升程下流型区域的分布范围

可为判断数值模拟所得流型的正确性提供参考。

Abstract

Flow-induced vibration and noise of control valves are experimentally and numerically studied to further investigate the relationships between flow pattern distribution

and vibration noise in a steam turbine. It is found that there exist two flow patterns in small and middle openings. Compared with core flow pattern

the flow pattern attached to the valve seat gets more stable with less noise. Different flow patterns may appear even under the same condition according to different adjustment methods of pressure ratios. A sound mutation caused by the converting of two different flow patterns is experimentally observed by continuously adjusting the pressure ratio

which can be used as a simple and practical way to determine the ranges of core and the annular flows.
