電磁閥 - 基本信息
電磁閥是依靠供電線圈產(chǎn)生的電磁力驅(qū)動活動鐵芯使閥瓣啟閉的閥門。通電前，閥門處于常閉（或常開）狀態(tài)，通電后電磁力驅(qū)動活動鐵芯，使閥門立即開啟（或關(guān)閉）。電磁閥的特點是動作迅速、結(jié)構(gòu)簡單、操作簡便。它主要用于自動截斷、接通或切換流體流向。因電磁力和活動鐵芯的動作行程都較小，這種閥門的公稱通徑一般不超過80毫米。電磁閥有多種結(jié)構(gòu)，一般分為無填料型和有填料型兩類（見圖）。無填料型電磁閥不用填料密封，套管內(nèi)充滿流體，除適用于一般流體外，更適用于氦、氟利昂（見制冷劑）和氨等貴重或有毒流體。有填料型電磁閥因使用填料，流體不與套管和鐵芯等接觸，大多用于高溫、低溫或強腐蝕性流體，但因有填料函，體積較大，且增加閥桿運動的摩擦力，故應(yīng)用較少。電磁閥的電源有交流、直流之分。用交流電的電磁閥的動作特別快，但易發(fā)熱、啟閉力較小。用直流電的電磁閥不易發(fā)熱，啟閉力較大，但動作沒有交流的快。
電磁閥 - 特點
（1）外漏堵絕，內(nèi)漏易控，使用安全。內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出，由電動、氣動、液動執(zhí)行機構(gòu)控制閥芯的轉(zhuǎn)動或移動。這都要解決長期動作閥桿動密封的外泄漏難題；唯有電磁閥是用電磁力作用于密封在隔磁套管內(nèi)的鐵芯完成，不存在動密封，所以外漏易堵絕。電動閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚至拉斷閥桿頭部；電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏，直至降為零。所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。（2）系統(tǒng)簡單，便接電腦，價格低謙。電磁閥本身結(jié)構(gòu)簡單，價格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護。更顯著的是所組成的自控系統(tǒng)簡單得多，價格要低得多。由于電磁閥是開關(guān)信號控制，與工控計算機連接十分方便。在當(dāng)今電腦普及，價格大幅下降的時代，電磁閥的優(yōu)勢就更加明顯。
（3）動作快遞，功率微小，外形輕巧。電磁閥響應(yīng)時間可以短至幾個毫秒，即使是先導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。由于自成回路，比之其它自控閥反應(yīng)更靈敏。設(shè)計得當(dāng)?shù)碾姶砰y線圈功率消耗很低，屬節(jié)能產(chǎn)品；還可做到只需觸發(fā)動作，自動保持閥位，平時一點也不耗電。電磁閥外形尺寸小，既節(jié)省空間，又輕巧美觀。
（4）調(diào)節(jié)精度受限，適用介質(zhì)受限。電磁閥通常只有開關(guān)兩種狀態(tài)，閥芯只能處于兩個極限位置，不能連續(xù)調(diào)節(jié)，（力圖突破的新構(gòu)思不少，但還都處于試驗試用階段）所以調(diào)節(jié)精度還受到一定限制。電磁閥對介質(zhì)潔凈度有較高要求，含顆粒狀的介質(zhì)不能適用，如屬雜質(zhì)須先濾去。另外，粘稠狀介質(zhì)不能適用，而且，特定的產(chǎn)品適用的介質(zhì)粘度范圍相對較窄。
（5）型號多樣，用途廣泛。電磁閥雖有先天不足，優(yōu)點仍十分突出，所以就設(shè)計成多種多樣的產(chǎn)品，滿足各種不同的需求，用途極為廣泛。電磁閥技術(shù)的進步也都是圍繞著如何克服先天不足，如何更好地發(fā)揮固有優(yōu)勢而展開。
