力士樂電磁閥線圈斷電時(shí)電磁力消失，動(dòng)鐵芯在彈簧力的作用下復(fù)位，直接關(guān)閉閥口，介質(zhì)不通。結(jié)構(gòu)簡單，動(dòng)作可靠，在零壓差和微真空下正常工作。常開型正好相反。 REXROTH電磁閥它由閥體、閥罩、電磁組件、彈簧及密封結(jié)構(gòu)等部件組成，動(dòng)鐵芯底部的密封塊借助彈簧的壓力將閥體進(jìn)氣口關(guān)閉。 力士樂電磁閥通電后，電磁鐵吸合，動(dòng)鐵芯上部帶彈簧的密封塊把排氣口關(guān)閉，氣流從進(jìn)氣口進(jìn)入膜頭，起到控制作用。當(dāng)失電時(shí)，電磁力消失，動(dòng)鐵芯在彈簧力作用下離開固定鐵芯，向下移動(dòng)，將排氣口打開，堵住進(jìn)氣口，膜頭氣流經(jīng)排氣口排出，膜片恢復(fù)原來位置。 REXROTH直動(dòng)式電磁閥有常閉型和常開型二種。常閉型斷電時(shí)呈關(guān)閉狀態(tài)，當(dāng)線圈通電時(shí)產(chǎn)生電磁力，使動(dòng)鐵芯克服彈簧力同靜鐵芯吸合直接開啟閥，介質(zhì)呈通路； 上海維特銳在德國設(shè)有分公司，專做進(jìn)口儀器儀表，氣動(dòng)液壓類產(chǎn)品15年，長期供應(yīng)力士樂電磁閥、REXROTH泵、力士樂放大器（可調(diào)現(xiàn)貨） 4WE 10 J3X/CG24N5K4
