style="text-indent:25px">　在氣動回路中，電磁控制換向閥的作用是控制氣流通道的通、斷或改變壓縮空氣的流動方向。主要工作原理是利用電磁線圈產(chǎn)生的電磁力的作用，推動閥芯切換，實現(xiàn)氣流的換向。按電磁控制部分對換向閥推動方式的不同，可以分為直動式電磁閥和先導(dǎo)式電磁閥。直動式電磁閥直接利用電磁力推動閥芯換向，而先導(dǎo)式換向閥則利用電磁先導(dǎo)閥輸出的先導(dǎo)氣壓推動閥芯換向。直動式電磁閥（常斷型）結(jié)構(gòu)的簡單剖面圖及工作原理。線圈通電時，靜鐵芯產(chǎn)生電磁力，閥芯受到電磁力作用向上移動，密封墊抬起，使接通，斷開，閥處于進氣狀態(tài)，可以控制氣缸動作。當(dāng)斷電時，閥芯靠彈簧力的作用恢復(fù)原狀，即斷通，閥處于排氣狀態(tài)。黑龍江直動式電磁閥有哪些電磁閥線圈長期帶電而燒壞。</p><div
