HERION先導(dǎo)式電磁閥

寧波思承流體有限公司是英國NORGREN（諾冠）、德國HERION(海隆)、德國BUSCHJOST（寶碩）、氣動、真空、液壓產(chǎn)品的一級簽約代理商，價格和交貨期非常有優(yōu)勢，同時寧波思承流體有限公司代理德國西門子SIEMENS電機(jī)和派克PARKER泵系列，部分型號還有現(xiàn)貨供應(yīng)，極有競爭優(yōu)勢。

先導(dǎo)式電磁閥

   原理：通電時，電磁力驅(qū)動先導(dǎo)閥打開先導(dǎo)閥，主閥上腔壓力迅速下降，在主閥上下腔內(nèi)形成壓差，依靠介質(zhì)壓力推動主閥關(guān)閉件上移，閥門開啟；斷電時，彈簧力把先導(dǎo)閥關(guān)閉，入口介質(zhì)壓力通過先導(dǎo)孔迅速進(jìn)入主閥上腔在上腔內(nèi)形成壓差，從而使主閥關(guān)閉。 

    特點(diǎn)：體積小，功率低，但介質(zhì)壓差范圍受限，必須滿足壓差條件。

電磁閥選型要領(lǐng)

    電磁閥選型首先應(yīng)該依次遵循安全性，可靠性，適用性，經(jīng)濟(jì)性四大原則，其次是根據(jù)六個方面的現(xiàn)場工況(即管道參數(shù)、流體參數(shù)、壓力參數(shù)、電氣參數(shù)、動作方式、特殊要求進(jìn)行 選擇)。

選型依據(jù)：

    一、根據(jù)管道參數(shù)選擇電磁閥的：通徑規(guī)格(即DN)、接口方式 

1、按照現(xiàn)場管道內(nèi)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(jù)用戶需要自由選擇。

   二、根據(jù)流體參數(shù)選擇電磁閥的：材質(zhì)、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(zhì)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(jié)構(gòu)類型的。   

3、流體狀態(tài)：大至有氣態(tài)，液態(tài)或混合狀態(tài)，特別是口徑大于DN25訂貨時一定要區(qū)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(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；zui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。

   四、電氣選擇：電壓規(guī)格應(yīng)盡量優(yōu)先選用AC220V、DC24較為方便。

   五、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、窯火焰監(jiān)測，則不能選常開的，應(yīng)選可*通電型。

   六、根據(jù)環(huán)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(huán)境：必須選用相應(yīng)防爆等級的電磁閥

2、當(dāng)管內(nèi)流體有倒流現(xiàn)象時，可選擇我公司OK71-N、OK72-N系列帶止回功能電磁閥。

3、當(dāng)需要對電磁閥進(jìn)行現(xiàn)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(yīng)選用防水，防塵品種(防護(hù)等級在IP54以上)。 

5、用于噴泉必須采用潛水型電磁閥(防護(hù)等級在IP68以上)。
