style="text-indent:25px">閥門(mén)回訊器種類(lèi)：一、機(jī)械式閥門(mén)回訊器：機(jī)械式閥門(mén)回訊器采用無(wú)源觸點(diǎn)的微動(dòng)開(kāi)關(guān)開(kāi)關(guān)形式可分：?jiǎn)蔚峨p擲SPDT、單刀單擲SPST、雙刀雙擲DPDT。二、感應(yīng)式閥門(mén)回訊器：磁感式閥門(mén)回訊器采用無(wú)源觸點(diǎn)的磁感應(yīng)接近開(kāi)關(guān)，開(kāi)關(guān)形式可分：?jiǎn)蔚峨p擲SPDT、單刀單擲SPST、但無(wú)雙刀雙擲DPDT。磁感接近一般分2線常開(kāi)或常閉，3線類(lèi)似于單刀雙擲SPDT，無(wú)常開(kāi)常閉。1、機(jī)械式屬于微動(dòng)開(kāi)關(guān)進(jìn)行機(jī)械撞擊；磁感式屬于磁動(dòng)力，故工作壽命方面機(jī)械式要小于磁感式的開(kāi)關(guān)。2、微動(dòng)開(kāi)關(guān)輸出電流大，磁感式輸出電流小3、工作電壓：微動(dòng)開(kāi)關(guān)交直流兩用；磁感式一般是直流，個(gè)別磁感可以交直流兩用。2、電感式閥門(mén)回訊器。</p><p style="text-indent:25px">隨著社會(huì)科技不斷進(jìn)步，回訊器在性能、款式、種類(lèi)等方面都得到了極大提升，現(xiàn)在市面上的回訊器分為工作回訊器和極限回訊器，工作回訊器指的就是用來(lái)給出機(jī)構(gòu)動(dòng)作到位信號(hào)。極限回訊器指的就是防止機(jī)構(gòu)動(dòng)作超出設(shè)計(jì)范圍而發(fā)生事故的開(kāi)關(guān)。不同種類(lèi)的回訊器在功能上有所不同。開(kāi)關(guān)元件有以下兩類(lèi)：慢動(dòng)開(kāi)關(guān)：開(kāi)關(guān)的接通和斷開(kāi)動(dòng)作切換時(shí)間與開(kāi)關(guān)的操動(dòng)速度有關(guān)，操動(dòng)速度越快，開(kāi)關(guān)的切換也越快?？靹?dòng)開(kāi)關(guān)：開(kāi)關(guān)的接通和斷開(kāi)的轉(zhuǎn)換時(shí)間與開(kāi)關(guān)**動(dòng)的速度無(wú)關(guān)，只要開(kāi)關(guān)操動(dòng)部件**動(dòng)到一定位置，開(kāi)關(guān)便發(fā)生接通和斷開(kāi)切換，此過(guò)程時(shí)間一般為彈簧彈跳所需時(shí)間，此時(shí)間極短，為一常數(shù)。開(kāi)關(guān)觸頭的接通和斷開(kāi)同時(shí)實(shí)現(xiàn)。當(dāng)開(kāi)關(guān)的觸頭分開(kāi)一定距離時(shí)，設(shè)備便停止運(yùn)轉(zhuǎn)，這是應(yīng)排除由于震動(dòng)而使觸頭重新接通，導(dǎo)致設(shè)備運(yùn)轉(zhuǎn)的可能性（開(kāi)關(guān)滯后效應(yīng)）。。當(dāng)操動(dòng)速度極為緩慢時(shí)。當(dāng)直流電流被斷開(kāi)時(shí)，要求電流飛弧迅速消失。對(duì)于以上情況的應(yīng)用，選用快動(dòng)型回訊器。回訊器又稱(chēng)行程開(kāi)關(guān)。</p><div
