SL30PA1-4X液控單向閥

型號SV和SL閥是錐閥結(jié)構(gòu)的液控單向閥，它可在關(guān)閉方向開啟而讓油液自由流動。

此類閥用于有液壓回路部分的隔離，當(dāng)管路破裂時，作為防止負載失壓的安全措施，或避免執(zhí)行器在液壓閉鎖時的爬行或漂移。

其組成主要包括閥體、閥芯 、壓縮彈簧和控制活塞和一個可選的釋壓球閥。

型號SV...

油液可以由A至B自由流動。在相反方向，閥芯被壓縮彈簧和系統(tǒng)壓力牢固的保持在其閥座上。

通過向控制口X提供壓力，控制活塞被推向右側(cè)。這樣閥芯離開閥座，油液由B至A流動。

為了確保閥開啟，需要一定的低控制壓力作用于控制活塞上

為了確保通過施加到控制閥芯上壓力閥能打開，要求一定的小先導(dǎo)壓力

型號SV..A..和SL..A.. (帶卸壓功能，)

該閥有一個附加的印載機構(gòu)，當(dāng)向X口提供控制壓力時，控制活塞被推向右側(cè)。它首先推開球閥芯，然后主閥芯離開其閥座。這樣，油液從B流向A,從而避免可能的壓力沖擊。

由于這種預(yù)開啟特征，可以實現(xiàn)缸中受壓液體的平穩(wěn)釋壓。

型號SL..

此閥的功能與SV型相同。

不同之處在于增加了泄油口Y。此處控制活塞 的環(huán)形面積與A口隔離。來自A口的壓力只作用于控制活塞 的面積A_上。

電磁閥線圈的額定電壓有DC12V、DC24V、AC24V（50/60Hz）、AC110V（50/60Hz）、AC220V（50/60Hz）、AC380V（50/60Hz）。一般在電氣設(shè)計時要么采用AC220V（不需加裝開關(guān)電源，成本低、線路簡單而便于維護）、要么采用DC24V（常用的的安全電壓、開關(guān)電源/電磁閥線圈都易于維修更換）。

檢測電磁閥好壞的方法：先給電磁閥通上被控制的介質(zhì)（帶壓力的液體、氣體<空氣>，壓力值為電磁閥使用壓力范圍的中間值），再給電磁閥線圈通電，如果被控制介質(zhì)有從通到斷或從斷到通的狀態(tài)的變化，那么電磁閥就是好的，否則就是有問題的。

止回閥是指依靠介質(zhì)本身流動而自動開、閉閥瓣，用來防止介質(zhì)倒流的閥門，又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動閥門，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機反轉(zhuǎn)，以及容器介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的 輔助系統(tǒng) 提供補給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉(zhuǎn)）與升降式止回閥（沿軸線移動）。
