AS32061A型WANDFLUH電磁換向閥六個現(xian)場(chang)工況要求

一、根據管道(dao)參數選擇電磁閥的：通(tong)徑規格(即DN)、接口方式(shi)(連接方式(shi))

1、按照現場管(guan)道內徑尺寸或流量要求(qiu)來(lai)確定通(tong)徑(DN)尺寸。

2、接(jie)口(kou)方式，一般DN>65要選擇法蘭接(jie)口(kou)，DN≤65則可(ke)根據用戶(hu)需要自由選擇螺紋(wen)式或者法蘭式

二、根據介質(zhi)種類選擇電磁閥的：閥體材(cai)質(zhi)、密封材(cai)料、溫度(du)組

1、腐蝕性流(liu)體(ti)：閥體(ti)材(cai)質宜選用不銹鋼或PTFE(聚四氟(fu)乙(yi)烯，俗稱塑(su)料(liao)王)，并選配氟(fu)橡膠或PTFE密封材(cai)料(liao)。

2、食用(yong)或超凈流體：閥(fa)體材質宜選用(yong)衛生級不銹鋼，并選配硅(gui)橡(xiang)膠密封(feng)材料。

3、高(gao)溫(wen)流體：要(yao)選擇采(cai)用(yong)耐高(gao)溫(wen)的電工材料(liao)和(he)密封材料(liao)制造的電磁閥，而(er)且要(yao)選擇活(huo)塞(sai)型原(yuan)理結(jie)構的。

4、流體(ti)狀態：大至有(you)氣態，液態或(huo)混合狀態，特(te)別(bie)是口徑大于25時一定要區分開(kai)來，因(yin)它(ta)與導孔參數有(you)關。

5、流體粘度：通常在50cSt以(yi)下可任意選擇，若超過此(ci)值，則(ze)需選用高(gao)粘度電磁(ci)閥。

6、流體清潔度：介質(zhi)(zhi)含(han)有(you)雜質(zhi)(zhi)時(shi)在電磁閥前安裝過濾器任選其它結構。

三、根據壓(ya)力(li)等級選擇電磁(ci)閥的：原理結構類型

1、當電磁閥需要長時間(jian)的(de)啟動，并且持續開啟的(de)時間(jian)大大超過(guo)關閉的(de)時間(jian)，宜選用常開型。

2、要是開和關(guan)頻繁(fan)切換或開啟的(de)時(shi)間短或開、關(guan)的(de)時(shi)間差不多時(shi)，則選常(chang)閉型。

3、但是有(you)些(xie)用(yong)于安(an)(an)全保護的工況，如爐窯火焰監測、燃氣(qi)泄露(lu)報(bao)警、消(xiao)防安(an)(an)全聯動系統，則應該選擇緊(jin)急切斷(duan)電(dian)磁(ci)閥(fa)，而(er)不宜選長期(qi)通(tong)電(dian)型(xing)(長期(qi)通(tong)電(dian)只(zhi)是一個相對概念)，更不能選常(chang)開式。

4、自(zi)保持式電(dian)磁閥(也(ye)稱：雙穩態)是(shi)一(yi)種新(xin)型技術，它主(zhu)要用于需要節約(yue)能(neng)源或低電(dian)壓(ya)驅動的場合。

四、電(dian)源(yuan)電(dian)壓選(xuan)擇：盡(jin)量優先選(xuan)擇常用的(de)AC220V，DC24V較為方便。

五(wu)、根據(ju)工作時間長短或(huo)特殊需要來選擇控制方(fang)式(shi)(shi)(shi)：常閉式(shi)(shi)(shi)、常開(kai)式(shi)(shi)(shi)、自保持、緊急切(qie)斷式(shi)(shi)(shi)(手動復位)

1、公稱壓(ya)力：這(zhe)個參數與其它(ta)通(tong)用(yong)閥門(men)的含義是一樣的，是根據管道公稱壓(ya)力或使(shi)用(yong)壓(ya)力的1.5倍來定。

2、工作壓差：是指電磁閥處于關閉或開啟狀態時，閥前端管路壓力減去閥后端管路壓力得到的數值;當無壓差、低壓差、真空時，必須選用直動式或分布直動式原理;當具備一定壓差以上時各種原理結構形式均可選用AS32061A型WANDFLUH電磁換向閥公司圖片：
