伺服閥

液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號后，相應輸出調制的流量和壓力。它既是電液轉換元件，也是功率放大元件，它能夠將小功率的微弱電氣輸入信號轉換為大功率的液壓能（流量和壓力）輸出。在電液伺服系統中，它將電氣部分與液壓部分連接起來(lái)，實(shí)現電液信號的轉換與液壓放大。電液伺服閥是電液伺服系統控制的核心。

伺服閥的介紹、定義：

液控伺服閥是在伺服系統中將電信號輸入轉換為功率較大的壓力或流量壓力信號輸出的執行元件。它是一種電液轉換和功率放大元件。伺服閥的靈敏度高，快速性好，能將很小的電信號（例如10毫安）轉換成很大的液壓功率（如幾十匹馬力以上），可以驅動(dòng)多種類(lèi)型的負載。過(guò)去人們曾把噴嘴檔板閥、射流管或滑閥伺服馬達等液壓放大裝置都列入伺服閥范圍內。20世紀70年代以來(lái)，伺服閥一般僅指電液伺服閥。

伺服閥的工作原理：

典型的伺服閥由永磁力矩馬達、噴嘴、檔板、閥芯、閥套和控制腔組成(見(jiàn)圖)。當輸入線(xiàn)圈通入電流時(shí)，檔板向右移動(dòng)，使右邊噴嘴的節流作用加強，流量減少，右側背壓上升；同時(shí)使左邊噴嘴節流作用減小，流量增加，左側背壓下降。閥芯兩端的作用力失去平衡, 閥芯遂向左移動(dòng)。高壓油從S流向C2，送到負載。負載回油通過(guò) C1流過(guò)回油口，進(jìn)入油箱。閥芯的位移量與力矩馬達的輸入電流成正比，作用在閥芯上的液壓力與彈簧力相平衡，因此在平衡狀態(tài)下力矩馬達的差動(dòng)電流與閥芯的位移成正比。如果輸入的電流反向，則流量也反向。 

伺服閥主要用在電氣液壓伺服系統中作為執行元件（見(jiàn)液壓伺服系統）。在伺服系統中，液壓執行機構同電氣及氣動(dòng)執行機構相比，具有快速性好、單位重量輸出功率大、傳動(dòng)平穩、抗干擾能力強等特點(diǎn)。另一方面，在伺服系統中傳遞信號和校正特性時(shí)多用電氣元件。因此，現代高性能的伺服系統也都采用電液方式，伺服閥就是這種系統的必需元件。

伺服閥結構比較復雜，造價(jià)高，對油的質(zhì)量和清潔度要求高。新型的伺服閥正試圖克服這些缺點(diǎn)，例如利用電致伸縮元件的伺服閥，使結構大為簡(jiǎn)化。另一個(gè)方向是研制特殊的工作油（如電氣粘性油）。這種工作油能在電磁的作用下改變粘性系數。利用這一性質(zhì)就可通過(guò)電信號直接控制油流。

應用領(lǐng)域：

電液伺服閥廣泛地應用于電液位置,速度,加速度,力伺服系統,以及伺服振動(dòng)發(fā)生器中.它具有體積小,結構緊湊,功率放大系數高,控制精度高,直線(xiàn)性好,死區小,靈敏度高,動(dòng)態(tài)性能好以及響應速度快等優(yōu)點(diǎn).
