按閥(fa)門(men)(men)(men)定(ding)位(wei)(wei)(wei)(wei)(wei)器輸(shu)入信(xin)號(hao)是(shi)(shi)模擬(ni)信(xin)號(hao)或(huo)數字(zi)(zi)信(xin)號(hao)，可分為普通(tong)(tong)閥(fa)門(men)(men)(men)定(ding)位(wei)(wei)(wei)(wei)(wei)器和現(xian)(xian)場(chang)總(zong)線(xian)(xian)(xian)電氣閥(fa)門(men)(men)(men)定(ding)位(wei)(wei)(wei)(wei)(wei)器。普通(tong)(tong)閥(fa)門(men)(men)(men)定(ding)位(wei)(wei)(wei)(wei)(wei)器的輸(shu)入信(xin)號(hao)是(shi)(shi)模擬(ni)氣壓或(huo)電流、電壓信(xin)號(hao)，現(xian)(xian)場(chang)總(zong)線(xian)(xian)(xian)電氣閥(fa)門(men)(men)(men)定(ding)位(wei)(wei)(wei)(wei)(wei)器的輸(shu)入信(xin)號(hao)是(shi)(shi)現(xian)(xian)場(chang)總(zong)線(xian)(xian)(xian)的數字(zi)(zi)信(xin)號(hao)。

按閥(fa)門定(ding)位(wei)器是否帶(dai)CPU可(ke)(ke)分(fen)為普(pu)通(tong)電氣(qi)(qi)閥(fa)門定(ding)位(wei)器和智(zhi)(zhi)能(neng)(neng)(neng)電氣(qi)(qi)閥(fa)門定(ding)位(wei)器。普(pu)通(tong)電氣(qi)(qi)閥(fa)門定(ding)位(wei)器沒(mei)有(you)CPU，因此，不(bu)具有(you)智(zhi)(zhi)能(neng)(neng)(neng)，不(bu)能(neng)(neng)(neng)處理(li)有(you)關的智(zhi)(zhi)能(neng)(neng)(neng)運算。智(zhi)(zhi)能(neng)(neng)(neng)電氣(qi)(qi)閥(fa)門定(ding)位(wei)器帶(dai)CPU，可(ke)(ke)處理(li)有(you)關智(zhi)(zhi)能(neng)(neng)(neng)運算，例如，可(ke)(ke)進行前向通(tong)道的非線性(xing)補(bu)償等(deng)，現場總線電氣(qi)(qi)閥(fa)門定(ding)位(wei)器還(huan)可(ke)(ke)帶(dai)PID等(deng)功(gong)能(neng)(neng)(neng)模塊(kuai)，實(shi)現相應的運算。

按動作的方(fang)向(xiang)可(ke)分為單(dan)向(xiang)閥門定位器(qi)和雙向(xiang)閥門定位器(qi)。單(dan)向(xiang)閥門定位器(qi)用于活塞式執行機構(gou)時，閥門定位器(qi)只有一個(ge)方(fang)向(xiang)起(qi)(qi)作用，雙向(xiang)閥門定位器(qi)作用在活塞式執行機構(gou)氣缸的兩(liang)側，從兩(liang)個(ge)方(fang)向(xiang)起(qi)(qi)作用。

按閥(fa)門定(ding)位(wei)器輸(shu)(shu)出(chu)和輸(shu)(shu)入(ru)(ru)信(xin)(xin)(xin)號(hao)(hao)的增(zeng)(zeng)(zeng)益(yi)符(fu)號(hao)(hao)分為(wei)(wei)正作(zuo)(zuo)用(yong)(yong)(yong)閥(fa)門定(ding)位(wei)器和反作(zuo)(zuo)用(yong)(yong)(yong)閥(fa)門定(ding)位(wei)器。正作(zuo)(zuo)用(yong)(yong)(yong)閥(fa)門定(ding)位(wei)器的輸(shu)(shu)入(ru)(ru)信(xin)(xin)(xin)號(hao)(hao)增(zeng)(zeng)(zeng)加(jia)時，輸(shu)(shu)出(chu)信(xin)(xin)(xin)號(hao)(hao)也增(zeng)(zeng)(zeng)加(jia)，因此，增(zeng)(zeng)(zeng)益(yi)為(wei)(wei)正。反作(zuo)(zuo)用(yong)(yong)(yong)閥(fa)門定(ding)位(wei)器的輸(shu)(shu)入(ru)(ru)信(xin)(xin)(xin)號(hao)(hao)增(zeng)(zeng)(zeng)加(jia)時，輸(shu)(shu)出(chu)信(xin)(xin)(xin)號(hao)(hao)減小(xiao)，因此，增(zeng)(zeng)(zeng)益(yi)為(wei)(wei)負。

閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)按輸入信(xin)(xin)號(hao)(hao)分為(wei)氣(qi)(qi)(qi)動閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)、電-氣(qi)(qi)(qi)閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)和智(zhi)能閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)。氣(qi)(qi)(qi)動閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)的(de)(de)輸入信(xin)(xin)號(hao)(hao)是標準氣(qi)(qi)(qi)信(xin)(xin)號(hao)(hao)，例如(ru)，20~100kPa氣(qi)(qi)(qi)信(xin)(xin)號(hao)(hao)，其(qi)輸出信(xin)(xin)號(hao)(hao)也是標準的(de)(de)氣(qi)(qi)(qi)信(xin)(xin)號(hao)(hao)。電氣(qi)(qi)(qi)閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)的(de)(de)輸入信(xin)(xin)號(hao)(hao)是標準電流(liu)(liu)(liu)或電壓(ya)信(xin)(xin)號(hao)(hao)，例如(ru)，4~20mA電流(liu)(liu)(liu)信(xin)(xin)號(hao)(hao)或1~5V電壓(ya)信(xin)(xin)號(hao)(hao)等(deng)，在電氣(qi)(qi)(qi)閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)內部將電信(xin)(xin)號(hao)(hao)轉(zhuan)換為(wei)電磁力，然后輸出氣(qi)(qi)(qi)信(xin)(xin)號(hao)(hao)到撥動控(kong)制(zhi)(zhi)閥(fa)。智(zhi)能電氣(qi)(qi)(qi)閥(fa)門(men)(men)定(ding)(ding)位(wei)器(qi)它將控(kong)制(zhi)(zhi)室輸出的(de)(de)電流(liu)(liu)(liu)信(xin)(xin)號(hao)(hao)轉(zhuan)換成驅動調(diao)節(jie)閥(fa)的(de)(de)氣(qi)(qi)(qi)信(xin)(xin)號(hao)(hao)，根據調(diao)節(jie)閥(fa)工作時閥(fa)桿(gan)摩擦力，抵消(xiao)介質壓(ya)力波動而產生的(de)(de)不平(ping)衡力，使(shi)閥(fa)門(men)(men)開度對應于控(kong)制(zhi)(zhi)室輸出的(de)(de)電流(liu)(liu)(liu)信(xin)(xin)號(hao)(hao)，并且可以進(jin)行智(zhi)能組(zu)態設置相(xiang)應的(de)(de)參數，達到改善控(kong)制(zhi)(zhi)閥(fa)性能的(de)(de)目的(de)(de)。
