簡要說明電磁換向閥工作原理

簡要說明一下電磁換向閥控制的液壓系統(tǒng)是怎么工作的。
以二位四通電磁閥爲例簡要說明電磁換向閥的電磁鐵是如何控制液體流向的。
如圖1(a)所示，進油口P進油，油液由油泵提供，回油口O從液壓缸接收回油，排入油箱。該二位四通閥由電磁鐵控制，當電磁鐵得電時，P與B連通，A與O連通。當電磁鐵斷電時， P與A連通，B與O連通。
(a)圖所示的工位爲電磁鐵得電，這時如果液壓泵工作，則液壓缸的右腔將進油，左腔排油，活塞桿縮回液壓缸。如果控制電磁鐵斷電，則液壓缸活塞桿將伸出。
同理可分析(b)圖中三位四通閥的控制過程。當電磁鐵YA1和YA2均未通電時，閥芯在兩端彈簧的作用下位于中位，該閥的滑閥機能（及閥芯處于中位時的功能）爲泵卸荷。
當閥芯位于中位時，這時液壓缸活塞桿保持原位。當電磁鐵YA1通電、YA2斷電時，P與A相通，O與B相通；當電磁鐵YA1斷電、YA2通電時，P與B相通，O與A相通。
