美國PARKER派克二位二通直動式電磁閥技術規(guī)范: 派克電磁閥適用介質:冷凍凍設備電磁閥經專門設計,能承受低于-320攝氏度的惡劣溫度,用于控制冷凍液。由于現有的密封材料用于如此低的溫度,克提供專門設計的用于氣密封截斷電磁閥。 PARKER直動式電磁閥電壓:DC-6,12,24,120,125(可按需求提供電壓);AC-24/60,110/120-50/60,220/240-50/60,440/480-50/60 線圈:標準F級,H級可選。 其它:額定溫度 AC交流:zui大-320-150°F DC交流:zui大-320-150°F 環(huán)境:32-77°F(標準) 安裝:重要:閥下游管道的內徑不得大于電磁閥標稱直徑,防止CO2膨脹導致閥結冰。電磁閥帶托架,便于直接安裝,另配一個NPT1/8接口,用于間接安裝。
PARKER電磁閥作為過程控制系統(tǒng)的執(zhí)行元件之一,其安全性和可靠性早已為廣大客戶所*,為更好地服務于這一領域的石油開采,煉油,天然氣,石化電廠,水處理等行業(yè)應用的多樣性和更可靠性的要求,及方便用戶和設計院的選型。 派克電磁閥其特點和性能如下:模塊化結構:PARKER電磁閥是用來控制流體的方向的自動化基礎元件,屬于執(zhí)行器;通常用于機械控制和工業(yè)閥門上面,對介質方向進行控制,從而達到對閥門開關的控制。 PARKER電磁閥從原理上分為三大類: 派克直動式電磁閥 原理:通電時,電磁線圈產生電磁力把關閉件從閥座上提起,閥門打開;斷電時,電磁力消失,彈簧把關閉件壓在閥座上,閥門關閉。 特點:在真空、負壓、零壓時能正常工作,但通徑一般不超過25mm。
派克分步直動式電磁閥 原理:它是一種直動和先導式相結合的原理,當入口與出口沒有壓差時,通電后,電磁力直接把先導小閥和主閥關閉件依次向上提起,閥門打開。當入口與出口達到啟動壓差時,通電后,電磁力先導小閥,主閥下腔壓力上升,上腔壓力下降,從而利用壓差把主閥向上推開;斷電時,先導閥利用彈簧力或介質壓力推動關閉件,向下移動,使閥門關閉。 特點:在零壓差或真空、高壓時亦能可*動作,但功率較大,要求必須水平安裝。
PARKER先導式電磁閥 原理:通電時,電磁力把先導孔打開,上腔室壓力迅速下降,在關 閉件周圍形成上低下高的壓差,流體壓力推動關閉件向上移動,閥門打開;斷電時,彈簧力把先導孔關閉,入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差,流體壓力推動關閉件向下移動,關閉閥門。 特點:流體壓力范圍上限較高,可任意安裝(需定制)但必須滿足流體壓差條件。
