Rexroth板接式導式單向閥,力士樂導式單向閥,力士樂電磁閥
Rexroth板接式導式單向閥利用過程本身的壓力或壓差來驅動控制閥動作,也可用.溫包式檢測元件將溫度轉換為壓力,然后驅動控制閥動作。其特點是結構簡單、操作方便,但會引起壓降,造成出口壓力的非線性,通常,穩壓精度在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合,出口壓力變化范圍可小于設定壓力的10%。控制閥具有節能功能,因此,在一些控制要求不高的場合被廣泛應用。自力式控制閥執行機構膜頭的輸入信號是控制閥前或閥后的壓力或閥兩端的壓差,或經溫包轉換后的壓力信號。執行機構的結構類似氣動薄膜執行機構?刂崎y對被控介質有一定要求,例如,自力式壓力控制閥的被控介質溫度應低于某一規定值,介質應干凈,當介質溫度較高時,例如,用于蒸汽或150℃以上的液體時,應設置冷凝器,使進入執行機構比較器內的介質溫度低于規定值。
