FESTO電(dian)磁閥在管道(dao)(dao)出現負(fu)(fu)壓的時候(hou)能(neng)快速(su)地吸進空氣，避免管道(dao)(dao)內由于負(fu)(fu)壓過(guo)大而失穩(wen)遭到破壞，而且復(fu)合式(shi)高(gao)(gao)(gao)速(su)排(pai)(pai)(pai)氣閥能(neng)減(jian)小降低管道(dao)(dao)漏水(shui)處吸入污(wu)水(shui)對(dui)管道(dao)(dao)的污(wu)染。大多的復(fu)合式(shi)高(gao)(gao)(gao)速(su)排(pai)(pai)(pai)氣閥的吸氣能(neng)力是排(pai)(pai)(pai)氣能(neng)力85%，為了保護(hu)管道(dao)(dao)的安全，避免管道(dao)(dao)失穩(wen)推(tui)薦用吸氣量(liang)為進氣量(liang)的80%計算使用復(fu)合式(shi)高(gao)(gao)(gao)速(su)排(pai)(pai)(pai)氣閥，需(xu)要(yao)注意的是管道(dao)(dao)的zui大負(fu)(fu)壓值一般不能(neng)超過(guo)0.035MPa，選擇復(fu)合式(shi)高(gao)(gao)(gao)速(su)排(pai)(pai)(pai)氣閥口徑時應該(gai)充分考(kao)慮。
FESTO電磁閥(fa)(fa)(fa)的(de)zui大(da)(da)好(hao)處優點是在任何高(gao)的(de)壓(ya)差的(de)情況下進排(pai)(pai)(pai)氣(qi)閥(fa)(fa)(fa)都不會(hui)自(zi)動關(guan)閉。當空管(guan)運行注水時，大(da)(da)量壓(ya)力水汽從(cong)復(fu)合式高(gao)速排(pai)(pai)(pai)氣(qi)閥(fa)(fa)(fa)排(pai)(pai)(pai)氣(qi)孔迅速排(pai)(pai)(pai)出，無論排(pai)(pai)(pai)氣(qi)時的(de)氣(qi)壓(ya)差多大(da)(da)，不排(pai)(pai)(pai)干凈空氣(qi)復(fu)合式高(gao)速排(pai)(pai)(pai)氣(qi)閥(fa)(fa)(fa)不會(hui)自(zi)動關(guan)閉。當管(guan)內空氣(qi)排(pai)(pai)(pai)干排(pai)(pai)(pai)完(wan)后，管(guan)道中的(de)水自(zi)FESTO電磁閥(fa)(fa)(fa)下部進入(ru)其(qi)閥(fa)(fa)(fa)內部，浮體罩內的(de)浮球上(shang)(shang)浮，直到將上(shang)(shang)升(sheng)到罩頂到閥(fa)(fa)(fa)口處，從(cong)而(er)進排(pai)(pai)(pai)氣(qi)閥(fa)(fa)(fa)就會(hui)自(zi)動關(guan)閉停止排(pai)(pai)(pai)氣(qi)不排(pai)(pai)(pai)水了。
FESTO電磁閥可靠性：
1、工作壽(shou)命，此項(xiang)不列入出(chu)廠試(shi)驗(yan)項(xiang)目，屬于型式(shi)試(shi)驗(yan)項(xiang)目。為(wei)確(que)保質量應選正規廠家的(de)名pai產品。
2、工作(zuo)制式：分長期工作(zuo)制，反復短時工作(zuo)制和短時工作(zuo)制三種。對于(yu)長時間閥門開(kai)通只(zhi)有短時關閉的情(qing)況，則宜選用(yong)常開(kai)電磁閥。
3、工(gong)作頻率：動作頻率要求(qiu)高(gao)時，結構應優(you)選(xuan)直動式(shi)電磁閥(fa)，電源(yuan)聽(ting)優(you)選(xuan)交流(liu)。
4、動作可靠性(xing)
嚴格地來說此項試(shi)驗尚未正(zheng)式列入中國電磁閥專(zhuan)業標準，為確保質量(liang)應選正(zheng)規廠家的名pai產品。有些(xie)場合動作(zuo)次數并不多(duo)，但對可靠性要求卻很高，如消防、緊急(ji)保(bao)護等 ，切不可掉以(yi)輕心。特別重要的，還應(ying)采取兩(liang)只連(lian)用雙保(bao)險。
