操作力矩：操作力矩是選擇閥門電動(dòng)裝置的較主要的參數(shù)。電動(dòng)裝置的輸出力矩應(yīng)為閥門操作較大力矩的1.2~1.5倍。2. 操作推力：閥門電動(dòng)裝置的主機(jī)結(jié)構(gòu)有兩種，一種是不配置推力盤的，此時(shí)直接輸出力矩;另一種是配置有推力盤的，此時(shí)輸出力矩通過(guò)推力盤中的閥桿螺母轉(zhuǎn)換為輸出推力。3. 輸出軸轉(zhuǎn)動(dòng)圈數(shù)：閥門電動(dòng)裝置輸出軸轉(zhuǎn)動(dòng)圈數(shù)的多少與閥門的公稱通徑、閥桿螺距、螺紋頭數(shù)有關(guān)，按M=H/ZS計(jì)算式中：M為電動(dòng)裝置應(yīng)滿足的總轉(zhuǎn)動(dòng)圈數(shù);H為閥門的開啟高度,mm;S為閥桿傳動(dòng)螺紋的螺距，mm;Z為閥桿螺紋頭數(shù)。濟(jì)南羅托克智能型多回轉(zhuǎn)電動(dòng)裝置訂購(gòu)電動(dòng)裝置是實(shí)現(xiàn)閥門程控、自控和遙控不可缺少的設(shè)備。</p><div
