Rexroth板接式導(dǎo)式單向閥,力士樂(lè)導(dǎo)式單向閥,力士樂(lè)電磁閥
Rexroth板接式導(dǎo)式單向閥利用過(guò)程本身的壓力或壓差來(lái)驅(qū)動(dòng)控制閥動(dòng)作，也可用．溫包式檢測(cè)元件將溫度轉(zhuǎn)換為壓力，然后驅(qū)動(dòng)控制閥動(dòng)作。其特點(diǎn)是結(jié)構(gòu)簡(jiǎn)單、操作方便，但會(huì)引起壓降，造成出口壓力的非線性，通常，穩(wěn)壓精度在10％一20％。帶指揮器作用的自力式控制閥可適用于小壓降和大流量的自力式控制場(chǎng)合，出口壓力變化范圍可小于設(shè)定壓力的10％�？刂崎y具有節(jié)能功能，因此，在一些控制要求不高的場(chǎng)合被廣泛應(yīng)用。自力式控制閥執(zhí)行機(jī)構(gòu)膜頭的輸入信號(hào)是控制閥前或閥后的壓力或閥兩端的壓差，或經(jīng)溫包轉(zhuǎn)換后的壓力信號(hào)。執(zhí)行機(jī)構(gòu)的結(jié)構(gòu)類似氣動(dòng)薄膜執(zhí)行機(jī)構(gòu)�？刂崎y對(duì)被控介質(zhì)有一定要求，例如，自力式壓力控制閥的被控介質(zhì)溫度應(yīng)低于某一規(guī)定值，介質(zhì)應(yīng)干凈，當(dāng)介質(zhì)溫度較高時(shí)，例如，用于蒸汽或150℃以上的液體時(shí)，應(yīng)設(shè)置冷凝器，使進(jìn)入執(zhí)行機(jī)構(gòu)比較器內(nèi)的介質(zhì)溫度低于規(guī)定值。
