2安全阀出口侧接入负压系统吗?蒸发器正压为0.4MPa,冷凝器为-77Kpa。我想让安全阀启跳后,介质进入冷凝器冷凝。行得通吗?负压对安全阀的整定压力有什么影响吗?

如果这样做会有什么潜在危害呢

L. 多花钱用好,用先导式安全阀,整定压力就不会受影响了

M. 负压对安全阀应该是有影响的,通常安全阀是靠弹簧设定起跳压力的。风险这个肯定很多,不过更多要根据工业状况进行分析;如极端状况安全阀起跳后不复位,真空系统会出现什么异常状况?不建议这么操作。

N. 安全阀不能保证绝对的无泄漏,如果你的安全阀经常起跳,你应该从工艺控制方面着手解决。如果把安全阀起跳当做常态,估计离事故就不远了。

O. 不会经常起跳。只是为了防止蒸发器器器器超压。蒸发器的介质易燃易爆。
