鋼制無(wu)閥過(guo)濾(lv)(lv)(lv)器(qi)應用(yong)(yong)于(yu)地(di)表水(shui)凈化(hua)，循環水(shui)旁流過(guo)濾(lv)(lv)(lv)，生(sheng)產廢水(shui)除懸(xuan)浮(fu)(fu)雜質，有機(ji)污水(shui)經(jing)生(sheng)化(hua)和二沉處(chu)理后的(de)過(guo)濾(lv)(lv)(lv)。鋼制無(wu)閥過(guo)濾(lv)(lv)(lv)器(qi)主(zhu)要利用(yong)(yong)虹(hong)(hong)吸(xi)(xi)原理進(jin)行定期反沖(chong)(chong)洗，過(guo)濾(lv)(lv)(lv)器(qi)進(jin)水(shui)出水(shui)、沖(chong)(chong)洗及排水(shui)均不用(yong)(yong)閥門(men)，靠(kao)水(shui)力作用(yong)(yong)自(zi)動運行。原水(shui)經(jing)過(guo)水(shui)管(guan)進(jin)入濾(lv)(lv)(lv)池(chi)通過(guo)濾(lv)(lv)(lv)層(ceng)自(zi)上(shang)而下的(de)過(guo)濾(lv)(lv)(lv)，后進(jin)入存水(shui)箱，充滿(man)后通過(guo)出水(shui)管(guan)入清水(shui)池(chi)。濾(lv)(lv)(lv)層(ceng)不斷留懸(xuan)浮(fu)(fu)物，造成阻力增加(jia)，而促使虹(hong)(hong)吸(xi)(xi)管(guan)內的(de)水(shui)位不斷升高，當(dang)水(shui)位達到虹(hong)(hong)吸(xi)(xi)輔助管(guan)管(guan)口時(shi)，水(shui)自(zi)該管(guan)落下，通過(guo)抽氣(qi)(qi)管(guan)借以帶(dai)走虹(hong)(hong)吸(xi)(xi)下降(jiang)的(de)空氣(qi)(qi)，當(dang)真空度達到一(yi)定值時(shi)，便發生(sheng)虹(hong)(hong)吸(xi)(xi)作用(yong)(yong)而使水(shui)自(zi)下而上(shang)通過(guo)濾(lv)(lv)(lv)層(ceng)對(dui)濾(lv)(lv)(lv)料進(jin)行反沖(chong)(chong)洗。當(dang)沖(chong)(chong)洗水(shui)箱水(shui)面(mian)下降(jiang)至虹(hong)(hong)吸(xi)(xi)破(po)壞管(guan)時(shi)，空氣(qi)(qi)進(jin)入虹(hong)(hong)吸(xi)(xi)管(guan)，破(po)壞虹(hong)(hong)吸(xi)(xi)作用(yong)(yong)，反沖(chong)(chong)洗結束，過(guo)濾(lv)(lv)(lv)重新開(kai)始。

　　鋼制無閥(fa)過(guo)(guo)(guo)濾器(qi)應用于地表水(shui)(shui)(shui)凈化，循環水(shui)(shui)(shui)旁流(liu)過(guo)(guo)(guo)濾，生產廢水(shui)(shui)(shui)除懸浮(fu)雜質，有機污水(shui)(shui)(shui)經(jing)生化和二沉處理(li)后(hou)的(de)過(guo)(guo)(guo)濾。鋼制無閥(fa)過(guo)(guo)(guo)濾器(qi)主要利用虹(hong)吸(xi)原理(li)進(jin)行(xing)定(ding)(ding)期(qi)反(fan)沖洗(xi)，過(guo)(guo)(guo)濾器(qi)進(jin)水(shui)(shui)(shui)出水(shui)(shui)(shui)、沖洗(xi)及排水(shui)(shui)(shui)均不(bu)(bu)(bu)用閥(fa)門(men)，靠水(shui)(shui)(shui)力(li)作用自動運行(xing)。原水(shui)(shui)(shui)經(jing)過(guo)(guo)(guo)水(shui)(shui)(shui)管(guan)進(jin)入濾池通過(guo)(guo)(guo)濾層自上(shang)而下(xia)的(de)過(guo)(guo)(guo)濾，后(hou)進(jin)入存水(shui)(shui)(shui)箱(xiang)，充滿后(hou)通過(guo)(guo)(guo)出水(shui)(shui)(shui)管(guan)入清水(shui)(shui)(shui)池。濾層不(bu)(bu)(bu)斷留懸浮(fu)物，造成阻力(li)增加，而促(cu)使虹(hong)吸(xi)管(guan)內的(de)水(shui)(shui)(shui)位不(bu)(bu)(bu)斷升(sheng)高，當水(shui)(shui)(shui)位達到(dao)虹(hong)吸(xi)輔(fu)助管(guan)管(guan)口時，水(shui)(shui)(shui)自該(gai)管(guan)落下(xia)，通過(guo)(guo)(guo)抽氣(qi)管(guan)借以(yi)帶(dai)走虹(hong)吸(xi)下(xia)降的(de)空氣(qi)，當真空度(du)達到(dao)一定(ding)(ding)值時，便發生虹(hong)吸(xi)作用而使水(shui)(shui)(shui)自下(xia)而上(shang)通過(guo)(guo)(guo)濾層對濾料進(jin)行(xing)反(fan)沖洗(xi)。當沖洗(xi)水(shui)(shui)(shui)箱(xiang)水(shui)(shui)(shui)面下(xia)降至虹(hong)吸(xi)破(po)(po)壞管(guan)時，空氣(qi)進(jin)入虹(hong)吸(xi)管(guan)，破(po)(po)壞虹(hong)吸(xi)作用，反(fan)沖洗(xi)結(jie)束，過(guo)(guo)(guo)濾重(zhong)新(xin)開始。
