摘要
分析了火力发电厂常用阀门的特点及应用范围,列出了阀门选择的一般原则和要求;总结了阀门常用材质的使用温度范围、执行标准和使用场合;比较了不同标准工业阀门和调节阀的泄漏等级参数,提出了阀门泄漏等级的一般要求。
The characteristics and application scope of valve used in thermal power plant were analyzed,and the criteria and requirement about valve selection were listed.The temperature scope,reference code and the allowable operation condition of valve material were also summarized.By comparing the leakage of industry valve with control valve in deferent codes,the general requirement of leakage level was pointed out.
