先導式電磁閥

   原理：通電時，電磁力驅動先導閥打開先導閥，主閥上腔壓力迅速下降，在主閥上下腔內形成壓差，依靠介質壓力推動主閥關閉件上移，閥門開啟；斷電時，彈簧力把先導閥關閉，入口介質壓力通過先導孔迅速進入主閥上腔在上腔內形成壓差，從而使主閥關閉。 

    特點：體積小，功率低，但介質壓差范圍受限，必須滿足壓差條件。

電磁閥選型要領

    電磁閥選型首先應該依次遵循安全性，可靠性，適用性，經濟性四大原則，其次是根據六個方面的現場工況(即管道參數、流體參數、壓力參數、電氣參數、動作方式、特殊要求進行 選擇)。

選型依據：

    一、根據管道參數選擇電磁閥的：通徑規格(即DN)、接口方式 

1、按照現場管道內徑尺寸或流量要求來確定通徑(DN)尺寸。

2、接口方式，一般>DN50要選擇法蘭接口，≤DN50則可根據用戶需要自由選擇。

   二、根據流體參數選擇電磁閥的：材質、溫度組

1、腐蝕性流體：宜選用耐腐蝕電磁閥和全不銹鋼；食用超凈流體：宜選用食品級不銹鋼材 質電磁閥。

2、高溫流體：要選擇采用耐高溫的電工材料和密封材料制造的電磁閥，而且要選擇活塞式 結構類型的。   

3、流體狀態：大至有氣態，液態或混合狀態，特別是口徑大于DN25訂貨時一定要區分開來。

4、流體粘度：通常在50cSt以下可任意選擇，若超過此值，則要選用高粘度電磁閥。

   三、根據壓力參數選擇電磁閥的：原理和結構品種

1、公稱壓力：這個參數與其它通用閥門的含義是一樣的，是根據管道公稱壓力來定。 

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；zui低工作壓差在0.04Mpa以上時直動式、分步直動式、先導式均可選用。

   四、電氣選擇：電壓規格應盡量優先選用AC220V、DC24較為方便。

   五、根據持續工作時間長短來選擇：常閉、常開、或可持續通電

1、當電磁閥需要長時間開啟，并且持續的時間多余關閉的時間應選用常開型。 

2、要是開啟的時間短或開和關的時間不多時，則選常閉型。  

3、但是有些用于安全保護的工況，如爐、窯火焰監測，則不能選常開的，應選可*通電型。

   六、根據環境要求選擇輔助功能：防爆、止回、手動、防水霧、水淋、潛水  

1、爆炸性環境：必須選用相應防爆等級的電磁閥

2、當管內流體有倒流現象時，可選擇我公司OK71-N、OK72-N系列帶止回功能電磁閥。

3、當需要對電磁閥進行現場人工操作時，可選擇我公司OK71-S、OK72-S系列帶手動功能電磁閥。  

4、露天安裝或粉塵多場合應選用防水，防塵品種(防護等級在IP54以上)。 

5、用于噴泉必須采用潛水型電磁閥(防護等級在IP68以上)。
