力士樂電液換向閥的結(jié)構(gòu)及工作原理
德國Rexroth電液換向閥是電磁換向閥和液控換向閥的組合，它是用電磁換向閥控制液控換向閥的動作，變換流體流動方向的控制閥。力士樂電液換向閥和液控換向閥主要用在流量超過電磁換向閥正常工作允許范圍的液壓系統(tǒng)中，對執(zhí)行元件的動作進行控制，或?qū)τ鸵旱牧鲃臃较蜻M行控制。
Rexroth螺紋插裝結(jié)構(gòu)的二位二通電液換向閥的工作原理示意圖［1］。該閥由先導(dǎo)閥和主閥兩部分組成。先導(dǎo)閥由先導(dǎo)閥芯1、前彈簧2、銜鐵4、后彈簧5、電磁線圈等組成；主閥由主閥芯3、閥殼體6、閥套7,組成。先導(dǎo)閥芯和主閥均采用錐閥式結(jié)構(gòu)，與液壓閥座采用線接觸，故密封性好，泄漏少，動作迅速。先導(dǎo)閥芯與銜鐵采用T型槽連接。主閥芯3的外表面上加工了3條均壓槽，以避免主閥芯3在運動過程中，承受不平衡的徑向力而產(chǎn)生的液壓卡緊現(xiàn)象。閥殼體6與閥套7，閥殼體6與閥體均采用螺紋聯(lián)接。電液換向閥的各處采用0形密封圈密封。先導(dǎo)閥采用12V直流濕式電磁鐵驅(qū)動，因為在相同條件下，由于濕式電磁閥比干式電磁閥具有較小的靜、動摩擦力，結(jié)構(gòu)尺寸相對較小，可消除閥體與電磁鐵間的密封，并且使用壽命長，工作可靠性高。
力士樂電液換向閥的工作原理為：當(dāng)電磁線圈斷電時，由于先導(dǎo)式溢流閥芯后彈簧5的剛度遠遠大于前彈簧2的剛度，因此在彈簧力的作用下，先導(dǎo)閥芯1封閉。此時，進口高壓油P1，一方面經(jīng)過主閥口流向出口P2，另一方面經(jīng)節(jié)流口d6流向主閥芯左腔，從而保證主閥芯左右兩腔的液壓力基本平衡，使主閥芯在彈簧力和液壓力的作用下可靠地關(guān)閉。當(dāng)電磁線圈通電時，先導(dǎo)閥芯1在電磁力作用下左移，主閥芯3的上腔的油液通過小孔d4與出口相通，由于節(jié)流小孔直徑d6遠遠小于主閥芯上小孔d4的直徑，因此主閥芯左右腔的液壓力相同。由于主閥芯采用差動式結(jié)構(gòu)，故在液體壓力作用下左移，從而實現(xiàn)換向功能。
力士樂電液換向閥的注意事項：產(chǎn)品可任意安裝，優(yōu)先考慮水平位置。液壓系統(tǒng)所用介質(zhì)必須過濾，過濾精度至少20μm。固定螺釘請按樣本中所列參數(shù)選用。
