style="text-indent:25px">閥門定位器輸入信號(hào)是模擬信號(hào)或數(shù)字信號(hào)，可分為普通閥門定位器和現(xiàn)場(chǎng)總線電氣閥門定位器。普通閥門定位器的輸入信號(hào)是模擬氣壓或電流、電壓信號(hào)，現(xiàn)場(chǎng)總線電氣閥門定位器的輸入信號(hào)是現(xiàn)場(chǎng)總線的數(shù)字信號(hào)。按動(dòng)作的方向可分為單向閥門定位器和雙向閥門定位器。單向閥門定位器用于活塞式執(zhí)行機(jī)構(gòu)時(shí)，閥門定位器只有一個(gè)方向起作用，雙向閥門定位器作用在活塞式執(zhí)行機(jī)構(gòu)氣缸的兩側(cè)，在兩個(gè)方向起作用。按閥門定位器輸出和輸入信號(hào)的增益符號(hào)分為正作用閥門定位器和反作用閥門定位器。正作用閥門定位器的輸入信號(hào)增加時(shí)，輸出信號(hào)也增加，因此，增益為正。反作用閥門定位器的輸入信號(hào)增加時(shí)，輸出信號(hào)減小，因此，增益為負(fù)。電器閥門定位器多少錢</p></p><br
