（1）國內(nèi)電站的溫度-壓力參數(shù)
國內(nèi)電站的溫度-壓力參數(shù)見表25-1。
（2）高溫高壓閥門性能規(guī)范
高溫高壓閥門性能規(guī)范見表25-2。
（3）閥門的溫度-壓力參數(shù)
按照我國國家和行業(yè)老標(biāo)準(zhǔn)，閥門的工作溫度小于和等于閥體、閥蓋材料的基準(zhǔn)溫度時(shí)，閥門的公稱壓力就是閥門的zui大工作壓力。公稱壓力用符號(hào) “PN”表示，閥門的基準(zhǔn)溫度是200°C。當(dāng)工作溫度高于200°C時(shí)，閥門的工作溫度及該溫度下的zui大允許工作壓力見表25-3?表25-6。
