style="text-indent:25px">電液換向閥是用控制油路中的壓力油推動閥芯。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向閥的動作，變換流體流動方向的控制閥。電液換向閥和液控?fù)Q向閥主要用在流量超過電磁換向閥正常工作允許范圍的液壓系統(tǒng)中，對執(zhí)行元件的動作進(jìn)行控制，或?qū)τ鸵旱牧鲃臃较蜻M(jìn)行控制。說明事項：1. 產(chǎn)品可任意安裝，優(yōu)先考慮水平位置。2. 液壓系統(tǒng)所用介質(zhì)必須過濾，過濾精度至少20μm。3. 固定螺釘請按樣本中所列參數(shù)選用。4. 與閥連接的表面，粗糙度要求Ra0.8，平面度要求0.01/100mm。麗水多路電磁換向閥如果交流電磁換向閥線圈內(nèi)部沒有經(jīng)過整流，導(dǎo)磁桿里面必定有一個短路環(huán)，否則交流電磁閥會嗡嗡響。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">電磁換向閥起先導(dǎo)作用，它可以改變控制液流的方向，從而改變液動換向閥的位置。由于操縱液動換向閥的液壓推力可以很大，所以主閥可以做得很大，允許有較大的流量通過。這樣用較小的電磁鐵就能控制較大的液流。比例式電磁換向閥：比例方向閥是以在閥芯外裝置的電磁線圈所產(chǎn)生的電磁力，來控制閥芯的移動，依靠控制線圈電流來控制方向閥內(nèi)閥芯的位移量，故可同時控制油流動的方向和流量。滑閥式換向閥：換向閥的結(jié)構(gòu)和工作原理：結(jié)構(gòu) 閥體：有多級沉割槽的圓柱孔；閥芯：有多段環(huán)行槽的圓柱體；分類：按工作位置數(shù)分（閥心相對于閥體的工作位置數(shù)）：二位、三位、四位；按通路數(shù)分（閥體對外連接的主要油口數(shù)，不包括控制油和泄漏油口）：二通、三通、四通、五通；按控制方式分：電磁、液動、電液、機(jī)動、手動?！?　</p><p style="text-indent:25px">根據(jù)壓力參數(shù)選擇電磁閥的：原理和結(jié)構(gòu)品種： 1、公稱壓力：這個參數(shù)與其它通用閥門的含義是一樣的，是根據(jù)管道公稱壓力來定； 2、工作壓力：如果工作壓力低則必須選用直動或分步直動式原理；較低工作壓差在0.04Mpa以上時直動式、分步直動式、先導(dǎo)式均可選用。電磁換向閥電氣選擇：電壓規(guī)格應(yīng)盡量優(yōu)先選用AC220V、DC24較為方便。根據(jù)持續(xù)工作時間長短來選擇：常閉、常開、或可持續(xù)通電。 1、當(dāng)電磁閥需要長時間開啟，并且持續(xù)的時間多余關(guān)閉的時間應(yīng)選用常開型 2、要是開啟的時間短或開和關(guān)的時間不多時，則選常閉型。 3、但是有些用于安全保護(hù)的工況，如爐、窖火焰監(jiān)測，則不能選常開的，應(yīng)選可長期通電型。電磁換向閥起先導(dǎo)作用，它可以改變控制液流的方向，從而改變液動換向閥的位置。</p><div

style="text-indent:25px">電磁閥常見故障及處理方法有哪些？線圈短路或斷路檢測方法：先用萬用表測量其通斷，阻值趨近于零或無窮大，那說明線圈短路或斷路。如果測量其阻值正常（大概是幾十歐），還不能說明線圈一定是好的（我有一次測得一個電磁閥線圈阻值大概50歐姆，但電磁閥無法動作，更換該線圈后一切正常），請進(jìn)行如下較終測試：找一個小螺絲刀放在穿于電磁閥線圈中的金屬桿的附近，然后給電磁閥通電，如果感覺到有磁性，那么電磁閥線圈是好的，否則是壞的。插頭/插座有問題故障現(xiàn)象：如果電磁閥是有插頭/插座的那種，有可能出現(xiàn)插座的金屬簧片問題（筆者就碰到過）、插頭上接線的問題（比如將電源線接到接地線上去了）等原因無法將電源送到線圈中。較好養(yǎng)成一個習(xí)慣：插頭插在插座上之后把固定螺絲擰上，線圈上在閥芯桿之后把固定螺母擰上。直動式電磁換向閥</p><p
