style="text-indent:25px">閥門定位器，按結(jié)構(gòu)分氣動閥門定位器、電氣閥門定位器及智能閥門定位器，是調(diào)節(jié)閥的主要附件，通常與氣動調(diào)節(jié)閥配套使用，它接受調(diào)節(jié)器的輸出信號，然后以它的輸出信號去控制氣動調(diào)節(jié)閥，當(dāng)調(diào)節(jié)閥動作后，閥桿的位移又通過機(jī)械裝置反饋到閥門定位器，閥位狀況通過電信號傳給上位系統(tǒng)。閥門定位器能夠增大調(diào)節(jié)閥的輸出功率，減少調(diào)節(jié)信號的傳遞滯后的情況發(fā)生，加快閥桿的移動速度，能夠提高閥門的線性度，克服閥桿的摩擦力并消除不平衡力的影響，從而保證調(diào)節(jié)閥的正確定位。主要工作原理：它將閥桿位移信號作為輸入的反饋測量信號,以控制器輸出信號作為設(shè)定信號，進(jìn)行比較，當(dāng)兩者有偏差時，改變其到執(zhí)行機(jī)構(gòu)的輸出信號，使執(zhí)行機(jī)構(gòu)動作，建立了閥桿位移量與控制器輸出信號之間的一一對應(yīng)關(guān)系。因此，閥門定位器組成以閥桿位移為測量信號，以控制器輸出為設(shè)定信號的反饋控制系統(tǒng)。該控制系統(tǒng)的操縱變量是閥門定位器去執(zhí)行機(jī)構(gòu)的輸出信號。上海小型氣動閥門生產(chǎn)企業(yè)由于管網(wǎng)中的氣動閥門，通常是啟閉不頻繁的，要求填料在數(shù)年內(nèi)不活動，填料亦不老化，長期保持密封效果。</p><div

style="text-indent:25px">對于氣動閥門活塞設(shè)計型，壓力越高，閥門的穩(wěn)定性與控制靈敏度就越好。氣動閥門是由角行程氣動執(zhí)行器與不同類型的閥體通過機(jī)械連接構(gòu)成氣動閥門。氣動閥門是借助壓縮空氣驅(qū)動的閥門，按照工作方式可分為切斷型和調(diào)節(jié)型兩大類，是工業(yè)現(xiàn)場儀表的一部分。主要分為氣動蝶閥、氣動球閥、氣動閘閥、氣動截止閥四大類系列。氣動閥門采用智能控制與定位，與電氣閥門定位器配套，輸入4～20mADC信號及0.4～0.7MPa氣源便可控制運(yùn)轉(zhuǎn)，實現(xiàn)對壓力、流量、溫度、液位等參數(shù)的調(diào)節(jié)。氣動閥門可配行程限位開關(guān)、電磁閥、減壓閥及0.4-0.7MPa氣源可實現(xiàn)開關(guān)操作，并送出二對無源觸點信號指示閥門的開關(guān)。</p><p style="text-indent:25px">電動閥門和氣動閥門的優(yōu)點。電動閥門：閥門電動執(zhí)行機(jī)構(gòu)主要應(yīng)用于動力廠或核動力廠，因為在高壓水系統(tǒng)需要一個平滑、穩(wěn)定和緩慢的過程。電動執(zhí)行機(jī)構(gòu)的主要優(yōu)點就是高度的穩(wěn)定和用戶可應(yīng)用的恒定的推力，電動執(zhí)行器的抗偏離能力是很好的，輸出的推力或力矩基本上是恒定的，可以很好的克服介質(zhì)的不平衡力，達(dá)到對工藝參數(shù)的準(zhǔn)確控制，所以控制精度比氣動執(zhí)行器要高。如果配用伺服放大器，可以很容易地實現(xiàn)正反作用的互換，也可以輕松設(shè)定斷信號閥位狀態(tài)（保持/全開/全關(guān)），而故障時，一定停留在原位，這是氣動執(zhí)行器所作不到，氣動執(zhí)行器必須借助于一套組合保護(hù)系統(tǒng)來實現(xiàn)保位。氣動閥門閥門氣動執(zhí)行器的執(zhí)行機(jī)構(gòu)和調(diào)節(jié)機(jī)構(gòu)是統(tǒng)一的整體，其執(zhí)行機(jī)構(gòu)有薄膜式和活塞式兩類?；钊叫谐涕L，適用于要求有較大推力的場合；而薄膜式行程較小，只能直接帶動閥桿。氣動執(zhí)行機(jī)構(gòu)的主要優(yōu)點：接受連續(xù)的氣信號，輸出直線位移（加電/氣轉(zhuǎn)換裝置后，也可以接受連續(xù)的電信號），有的配上搖臂后，可輸出角位移，有正、反作用功能，移動速度大，但負(fù)載增加時速度會變慢，輸出力與操作壓力有關(guān)。氣動閥門的使用手冊。</p><div
