力士樂(lè)電液換向閥的結(jié)構(gòu)及工作原理

 　 德國(guó)Rexroth電液換向閥是電磁換向閥和液控?fù)Q向閥的組合，它是用電磁換向閥控制液控?fù)Q向閥的動(dòng)作，變換流體流動(dòng)方向的控制閥。力士樂(lè)電液換向閥和液控?fù)Q向閥主要用在流量超過(guò)電磁換向閥正常工作允許范圍的液壓系統(tǒng)中，對(duì)執(zhí)行元件的動(dòng)作進(jìn)行控制，或?qū)τ鸵旱牧鲃?dòng)方向進(jìn)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(dòng)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(yùn)動(dòng)過(guò)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(dòng)，因?yàn)樵谙嗤瑮l件下，由于濕式電磁閥比干式電磁閥具有較小的靜、動(dòng)摩擦力，結(jié)構(gòu)尺寸相對(duì)較小，可消除閥體與電磁鐵間的密封，并且使用壽命長(zhǎng)，工作可靠性高。

力士樂(lè)電液換向閥的工作原理為：當(dāng)電磁線圈斷電時(shí)，由于先導(dǎo)式溢流閥芯后彈簧5的剛度遠(yuǎn)遠(yuǎn)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(shí)，進(jìn)口高壓油P1，一方面經(jīng)過(guò)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(shí)，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(guò)小孔d4與出口相通，由于節(jié)流小孔直徑d6遠(yuǎn)遠(yuǎn)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(dòng)式結(jié)構(gòu)，故在液體壓力作用下左移，從而實(shí)現(xiàn)換向功能。

力士樂(lè)電液換向閥的注意事項(xiàng)：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(guò)濾，過(guò)濾精度至少20μm。固定螺釘請(qǐng)按樣本中所列參數(shù)選用。
