The author: Time:2021/5/12

  根據(jù)IEC對(duì)調(diào)節(jié)閥的定義:調(diào)節(jié)閥是由執(zhí)行機(jī)構(gòu)和閥體部件兩部分組成,即調(diào)節(jié)閥=執(zhí)行機(jī)構(gòu)+其中,執(zhí)行機(jī)構(gòu)是調(diào)節(jié)閥的推動(dòng)裝置,它按信號(hào)壓力的大小產(chǎn)生相應(yīng)的推力,使推桿產(chǎn)生相應(yīng)的位移,從而帶動(dòng)調(diào)節(jié)閥的閥芯動(dòng)作;閥體部件是調(diào)節(jié)閥的調(diào)節(jié)部份,它直接與介質(zhì)接觸,通過(guò)執(zhí)行機(jī)構(gòu)推桿的位移,改變調(diào)節(jié)閥的節(jié)流面積,達(dá)到調(diào)節(jié)的目的。
