Huade北京華德液壓電磁動作方向控制閥：

當(dāng)兩個電磁閥線圈通電時，平衡孔回路關(guān)閉，泄流孔回路打開，活塞上腔泄壓，活塞上行，閥門打開。反之，活塞下行，閥門關(guān)閉。在閥門開啟和關(guān)閉過程中，可將流量（流速）信號及閥塞位置信號傳送給計算機(jī)，經(jīng)過計算機(jī)處理后發(fā)出相應(yīng)的指令，控制兩個電磁導(dǎo)閥的通、斷電狀態(tài)，使活塞的上下腔的液壓差產(chǎn)生變化，從而將活塞控制在所需的開啟高度上，實現(xiàn)對管道介質(zhì)流量的控制。

1、按照流體在管道的流動方向，如果只允許流體向一個方向流動，這樣的閥叫做單向型控制閥，比如單向閥，梭閥等；可以改變流體流向的控制閥叫做換向閥，比如常用的兩位兩通，兩位三通，兩位五通，三位五通等。

2、按照控制方式可分為電磁閥，機(jī)械閥，氣控閥，人控閥。其中電磁閥又可以分為單和雙電控閥兩種；機(jī)械閥可分為球頭閥，滾輪閥等多種；氣控閥也可分為單氣控和雙氣控閥；人力閥可以分為手動閥，腳踏閥兩種。

3、按工作原理可以分為直動閥和先導(dǎo)閥，直動閥就是靠人力或者電磁力，氣動力直接實現(xiàn)換向要求的閥；先導(dǎo)閥是由先導(dǎo)頭和閥主體2部分構(gòu)成，有先導(dǎo)頭活塞驅(qū)動閥主體里面的閥桿實現(xiàn)換向。

4、根據(jù)換向閥桿的工作位置可以將閥分為2way，3way閥。

5、根據(jù)閥上氣孔的多少來進(jìn)行劃分，可以分為2port，3port，5port閥。
