H-4WEH25C6X/6HG24N9TK4電液換向閥

電液換向閥是由電磁換向閥作先導閥與液動換向閥組合而成，由電磁閥引進油液，推動主滑閥運動，使主油路換向。主要用于改變油流方向，改變油馬達旋轉方向，和油缸的運動方向等。也可用以完成卸荷和順序動作等用途。適用于大流量的液壓系統(tǒng)。液動閥換向的快慢可用其控制油路中的單向節(jié)流閥來調節(jié)。

 

電液動滑閥既能實現換向的緩沖，避免液壓系統(tǒng)的換向沖擊，同時又能用較小的電磁鐵控制較大的液流，所以常在流量較大的系統(tǒng)中應用。

 

電液換向閥有二位與三位，均是四通。按其電磁閥的電源電壓可分為交流(110V/220V/380V)、直流(24V/110V/220V)兩種。

 

P為進油口，O為回油口，AB至油缸兩端。K為電磁先導閥的進油口，L為電磁先導閥的回油口，L應該直通回油池，不應通過任何的背壓閥，亦避免與回油O連通。

 

主要結構品種：

1．電液換向的先導電磁閥為NG6、NG10二種。

2．電液換向閥的控制電磁鐵有干式型、濕式型二種結構，工作電源有交流、直流二種。

3．電液換向閥有二位四通無彈簧型、三位四通彈簧對中型及行程調節(jié)型三種，后者可

借助調節(jié)螺釘改變閥芯的移動距離，以調整進出閥的流量，起到節(jié)流調速的作用。

4．在電磁導閥與液動閥的控制之間，可加入阻尼調節(jié)閥，以控制主閥芯的換向速度。

方向控制閥

方向控制閥用于控制或調節(jié)液壓系統(tǒng)或回路中方向及其通和斷,從而控制執(zhí)行元件的

運動方向及其啟動、停止的閥。如單向閥、換向閥等;

大型鋼廠現場采用的主要方向控制閥，如:電磁換向閥、手動換向閥、電液換向閥、單向閥、方向插件，插裝閥。

3、4WEH..型方向閥

型號4WEH..型方向閥WEH型方向閥是-種電液操作的方向滑閥。它們用于控制液流的開啟、停止和方向。

此類閥組成主要包括閥體( 1 )主控制閥芯(2 )一個或兩個復位彈簧( 3.1 )和(3.2 ),帶一個或兩個電磁鐵:電磁鐵"a” (5.1 ),電磁鐵"b" (5.2 )的先導閥(4)。

主閥閥芯由彈簧或液壓力保持在中位或初始位置。在初始位置, 兩個彈簧腔( 6 )和( 8 )通過先導閥無壓的油箱連通。經過控制油路(7 )向先導閥(4)供油�？刂撇纯梢杂蓛炔炕蛲獠抗┙o( 外部供給油口X )當先導閥操作時,如電磁鐵"a”得電,先導滑閥(10)向左移動,因此彈簧腔(8)獲得先導油壓力而彈簧腔(6)保持無壓狀態(tài)。

先導壓力施壓于主閥芯的左端, 并克服彈簧力( 3.1),其結果,主閥的P至B和A至T被接通。當電磁鐵斷電,先導閥回復至初始位置(帶定位機構滑閥除外),彈簧腔( 8 )向油箱卸荷。

控制油從彈簧腔經先導閥排入Y口。控制油可內部或外部供油和回油外部經油口Y )可選擇的應急手動操作( 9 ),在電磁鐵不通電情況下,可對先導滑閥( 10 )進行操作。

電液閥是由一個主閥和兩個電磁閥組成，主閥響應速度的控制是兩個柱塞閥，安裝于主閥的入口和出口。通過兩個柱塞閥細微調節(jié)主閥的啟閉速度。調整這些裝置（柱塞閥）以控制流入和流出活塞上方介質的流量。達到主閥啟閉速度能基于介質的粘度及壓力調整的目的。

換向閥有兩組密封組件。每組密封組件(圖2)由閥瓣、密封圈、調整塊、調節(jié)螺釘、夾板和螺栓組成。閥瓣為碳鋼板焊件，設有加強筋，即增加閥瓣強度又起導向作用，保證每組閥瓣間的同軸度。閥瓣上鑲嵌聚氨脂橡膠圈，該材料具有耐油、耐磨損、性能穩(wěn)定、密封良好和使用壽命長的特點。在凸輪的作用下，密封圈的球面與閥體密封面相接觸產生擠壓彈性變形，達到密封效果。調整塊和調節(jié)螺釘在兩組密封組件不能同步到位時可起調整作用，確保各通道密封性能同步到位。

電液比例閥是比例控制系統(tǒng)中的主要功率放大元件,按輸入電信號指令連續(xù)地成比例地控制液壓系統(tǒng)的壓辦流量等參數。與伺 服控制系統(tǒng)中的伺服閥相比,在某些方面還有一-定的性能差距(主要性能比較如表1所示),但它顯著的優(yōu)點是抗污染能力強,大大地減少了由污染而造成的工作故障,提高了液壓系統(tǒng)的工作穩(wěn)定性和可靠性。另一方面比例閥的成本比伺服閥低，結構也簡單,已在許多場合獲得廣泛應用。
