非火灾用主安全阀的最大泄放压力、火
灾用辅助安全阀的最大设定压力 非火灾用辅助安全阀的最大设定压力
主安全阀的最大设定压力
回座压力
表1表明了不同情况下被保护系统设置安全阀的最大泄放压力、最大设定压力的数值与保护容器的设计压力（或最大允许工作压力）数值的比例关系。

（参考：化工部标准 HG/T 20570.2-95）
二、请按下式确定安全阀的开启压力（且其不得大于容器设计压力）：
1、当压力容器工作压力（Pw ）小于0.5MPa 时，安全阀开启压力=Pw+0.05MPa ；
2、当压力容器工作压力（Pw ）大于等于0.5MPa 时，安全阀开启压力=1.10PwMPa 。

安全阀公称通径与流道直径对照表摘要：1.安全阀公称通径与流道直径的概念2.安全阀公称通径与流道直径的关系3.安全阀公称通径对照表正文：一、安全阀公称通径与流道直径的概念安全阀是一种保护设备，用于在系统压力超过规定值时自动排放介质，以保证系统的安全运行。

在安全阀中，有几个重要的尺寸参数，包括公称通径、流道直径等。

公称通径，又称平均外径，是指安全阀（管口）标准化以后的标准直径，以dn 表示，单位为mm。

它是参考的一个数值，与加工尺寸呈不严格的关系。

公称通径的数值是取阀门的外径与内径的平均值，习惯上也称为口径。

流道直径，定义为安全阀对应于流道面积的直径，亦称为喉径。

流道直径应该小于公称通径，其具体数值需要参考相应的标准规范。

二、安全阀公称通径与流道直径的关系安全阀的公称通径与流道直径之间的关系，根据安全阀的类型和设计要求有所不同。

一般来说，全启式安全阀的公称直径比流道直径大二级，微启式安全阀的公称直径比流道直径大一级。

以全启式安全阀为例，如果安全阀直径dn50mm，那么流道直径就是dn32mm，中间相隔dn40mm；如果安全阀直径dn80mm，那么流道直径就是dn50mm，中间相隔dn65mm。

而微启式安全阀的公称直径比流道直径大一级，例如，如果安全阀直径dn50mm，那么流道直径就是dn40mm；如果安全阀直径dn80mm，那么流道直径就是dn65mm，以此类推。

三、安全阀公称通径对照表安全阀公称通径对照表（公称通径对照表dn10）列出了不同公称通径对应的流道直径和喉径。

这些数据可以帮助工程师在设计和选用安全阀时，根据系统的具体要求，选择合适的安全阀尺寸。

总结：安全阀公称通径与流道直径是安全阀的两个重要尺寸参数。

它们之间的关系取决于安全阀的类型和设计要求。
