pressure)，表示符號(hào)PN，在一定溫度下應(yīng)用時(shí)允許的比較大工作壓力。對(duì)碳鋼閥體的控制閥，指200℃以下應(yīng)用時(shí)允許的比較大工作壓力；對(duì)鑄鐵閥體，指120℃以下應(yīng)用時(shí)允許的比較大工作壓力；對(duì)不銹鋼閥體的控制閥，指250℃以下應(yīng)用時(shí)允許的比較大工作壓力。當(dāng)工作溫度升高時(shí)，閥體的耐壓會(huì)降低。例如，公稱壓力為6.4MPa（PN64）的碳鋼控制閥，用于300℃時(shí)的耐壓為5.2MPa，用400℃時(shí)的耐壓為4.1MPa，用于450℃時(shí)的耐壓為2.9MPa。因此，控制閥公稱壓力的確定不*要根據(jù)比較高工作壓力，還需根據(jù)比較高工作溫度和材質(zhì)特性，而不**只需滿足公稱壓力大于工作壓力。湖北GID型-電動(dòng)高真空蝶閥真空閥門大致有兩種:一種是關(guān)閉后隔絕大氣和真空空間的開關(guān)形閥門,另一種是調(diào)整通氣量的流量可變閥門。</p><div
