電磁閥現貨
電磁閥 - 基本信息
電磁閥是依靠供電線圈產生的電磁力驅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，通電后電磁力驅動活動鐵芯，使閥門立即開啟（或關閉）。電磁閥的特點是動作迅速、結構簡單、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。電磁閥有多種結構，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，但易發熱、啟閉力較小。用直流電的電磁閥不易發熱，啟閉力較大，但動作沒有交流的快。
電磁閥 - 特點
（1）外漏堵絕，內漏易控，使用安全。內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、液動執行機構控制閥芯的轉動或移動。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，容易產生內漏，甚至拉斷閥桿頭部；電磁閥的結構型式容易控制內泄漏，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。（2）系統簡單，便接電腦，價格低謙。電磁閥本身結構簡單，價格也低，比起調節閥等其它種類執行器易于安裝維護。更顯著的是所組成的自控系統簡單得多，價格要低得多。由于電磁閥是開關信號控制，與工控計算機連接十分方便。在當今電腦普及，價格大幅下降的時代，電磁閥的優勢就更加明顯。
（3）動作快遞，功率微小，外形輕巧。電磁閥響應時間可以短至幾個毫秒，即使是先導式電磁閥也可以控制在幾十毫秒內。由于自成回路，比之其它自控閥反應更靈敏。設計得當的電磁閥線圈功率消耗很低，屬節能產品；還可做到只需觸發動作，自動保持閥位，平時一點也不耗電。電磁閥外形尺寸小，既節省空間，又輕巧美觀。
（4）調節精度受限，適用介質受限。電磁閥通常只有開關兩種狀態，閥芯只能處于兩個極限位置，不能連續調節，（力圖突破的新構思不少，但還都處于試驗試用階段）所以調節精度還受到一定限制。電磁閥對介質潔凈度有較高要求，含顆粒狀的介質不能適用，如屬雜質須先濾去。另外，粘稠狀介質不能適用，而且，特定的產品適用的介質粘度范圍相對較窄。
（5）型號多樣，用途廣泛。電磁閥雖有先天不足，優點仍十分突出，所以就設計成多種多樣的產品，滿足各種不同的需求，用途極為廣泛。電磁閥技術的進步也都是圍繞著如何克服先天不足，如何更好地發揮固有優勢而展開。
