氣動減壓閥的工作原理：氣動減壓閥由執(zhí)行機(jī)構(gòu)和調(diào)節(jié)機(jī)構(gòu)組成。執(zhí)行機(jī)構(gòu)是調(diào)節(jié)閥的推力部件，它按控制信號壓力的大小產(chǎn)生相應(yīng)的推力，推動調(diào)節(jié)機(jī)構(gòu)動作。閥體是氣動調(diào)節(jié)閥的調(diào)節(jié)部件，它直接與調(diào)節(jié)介質(zhì)接觸，調(diào)節(jié)該流體的流量。

公稱壓力：(Nominal pressure)，表示符號PN，在一定溫度下應(yīng)用時(shí)允許的工作壓力。對碳鋼閥體的控制閥，指200℃以下應(yīng)用時(shí)允許的工作壓力；對鑄鐵閥體，指120℃以下應(yīng)用時(shí)允許的工作壓力；對不銹鋼閥體的控制閥，指250℃以下應(yīng)用時(shí)允許的工作壓力。當(dāng)工作溫度升高時(shí)，閥體的耐壓會降低。
