浅谈防喘振阀的工程设计选型要点

DISCUSSION ON ANTI-SURGE VALVE SELECTION IN ENGINEERING DESIGN

从离心压缩机防喘振阀的型式选择、CV值计算选用、防喘振阀的速开时间、防喘振阀流量特性等方面,详细介绍了离心式压缩机防喘振阀的选用要点。从工程实际的角度介绍了不合适的CV值或速开时间过长可能导致的喘振问题,并提供了可行的解决思路,对离心压缩机防喘振阀的合理选用有一定指导意义。

This paper introduces in detail the key points in the selection of anti-surge valve for centrifugal compressor from the aspects of the type selection of anti-surge valve,the calculation and selection of CV value,and the quick opening time and flow characteristics of anti-surge valve.Based on practical engineering,inappropriate CV valve and long quick opening time may cause surging problems.Some feasible solutions are put forward,providing guidance for the rational selection of anti-surge valve for centrifugal compressors.
