H-4WEH25C6X/6HG24N9TK4電液換向閥
電液換向閥是由電磁換向閥作先導(dǎo)閥與液動(dòng)換向閥組合而成，由電磁閥引進(jìn)油液，推動(dòng)主滑閥運(yùn)動(dòng)，使主油路換向。主要用于改變油流方向，改變油馬達(dá)旋轉(zhuǎn)方向，和油缸的運(yùn)動(dòng)方向等。也可用以完成卸荷和順序動(dòng)作等用途。適用于大流量的液壓系統(tǒng)。液動(dòng)閥換向的快慢可用其控制油路中的單向節(jié)流閥來(lái)調(diào)節(jié)。
電液動(dòng)滑閥既能實(shí)現(xiàn)換向的緩沖，避免液壓系統(tǒng)的換向沖擊，同時(shí)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(yīng)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(jìn)油口，O為回油口，AB至油缸兩端。K為電磁先導(dǎo)閥的進(jìn)油口，L為電磁先導(dǎo)閥的回油口，L應(yīng)該直通回油池，不應(yīng)通過(guò)任何的背壓閥，亦避免與回油O連通。
主要結(jié)構(gòu)品種：
1．電液換向的先導(dǎo)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(jié)構(gòu)，工作電源有交流、直流二種。
3．電液換向閥有二位四通無(wú)彈簧型、三位四通彈簧對(duì)中型及行程調(diào)節(jié)型三種，后者可
借助調(diào)節(jié)螺釘改變閥芯的移動(dòng)距離，以調(diào)整進(jìn)出閥的流量，起到節(jié)流調(diào)速的作用。
4．在電磁導(dǎo)閥與液動(dòng)閥的控制之間，可加入阻尼調(diào)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(diào)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(yùn)動(dòng)方向及其啟動(dòng)、停止的閥。如單向閥、換向閥等;
大型鋼廠現(xiàn)場(chǎng)采用的主要方向控制閥，如:電磁換向閥、手動(dòng)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(hào)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(kāi)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(gè)或兩個(gè)復(fù)位彈簧( 3.1 )和(3.2 ),帶一個(gè)或兩個(gè)電磁鐵:電磁鐵"a” (5.1 ),電磁鐵"b" (5.2 )的先導(dǎo)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(gè)彈簧腔( 6 )和( 8 )通過(guò)先導(dǎo)閥無(wú)壓的油箱連通。經(jīng)過(guò)控制油路(7 )向先導(dǎo)閥(4)供油�？刂撇纯梢杂蓛�(nèi)部或外部供給( 外部供給油口X )當(dāng)先導(dǎo)閥操作時(shí),如電磁鐵"a”得電,先導(dǎo)滑閥(10)向左移動(dòng),因此彈簧腔(8)獲得先導(dǎo)油壓力而彈簧腔(6)保持無(wú)壓狀態(tài)。
先導(dǎo)壓力施壓于主閥芯的左端, 并克服彈簧力( 3.1),其結(jié)果,主閥的P至B和A至T被接通。當(dāng)電磁鐵斷電,先導(dǎo)閥回復(fù)至初始位置(帶定位機(jī)構(gòu)滑閥除外),彈簧腔( 8 )向油箱卸荷。
控制油從彈簧腔經(jīng)先導(dǎo)閥排入Y口�？刂朴涂蓛�(nèi)部或外部供油和回油外部經(jīng)油口Y )可選擇的應(yīng)急手動(dòng)操作( 9 ),在電磁鐵不通電情況下,可對(duì)先導(dǎo)滑閥( 10 )進(jìn)行操作。
電液閥是由一個(gè)主閥和兩個(gè)電磁閥組成，主閥響應(yīng)速度的控制是兩個(gè)柱塞閥，安裝于主閥的入口和出口。通過(guò)兩個(gè)柱塞閥細(xì)微調(diào)節(jié)主閥的啟閉速度。調(diào)整這些裝置（柱塞閥）以控制流入和流出活塞上方介質(zhì)的流量。達(dá)到主閥啟閉速度能基于介質(zhì)的粘度及壓力調(diào)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(diào)整塊、調(diào)節(jié)螺釘、夾板和螺栓組成。閥瓣為碳鋼板焊件，設(shè)有加強(qiáng)筋，即增加閥瓣強(qiáng)度又起導(dǎo)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(zhǎng)的特點(diǎn)。在凸輪的作用下，密封圈的球面與閥體密封面相接觸產(chǎn)生擠壓彈性變形，達(dá)到密封效果。調(diào)整塊和調(diào)節(jié)螺釘在兩組密封組件不能同步到位時(shí)可起調(diào)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(hào)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(shù)。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(diǎn)是抗污染能力強(qiáng),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(jié)構(gòu)也簡(jiǎn)單,已在許多場(chǎng)合獲得廣泛應(yīng)用。
