FESTO過(guò)濾減壓閥

FESTO減壓閥是氣動(dòng)調(diào)節(jié)閥的一個(gè)*配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個(gè)定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動(dòng)力用于調(diào)節(jié)控制。 按結(jié)構(gòu)形式可分為薄膜式、彈簧薄膜式、活塞式、杠桿式和波紋管式；按閥座數(shù)目可分為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式。

FESTO比例式減壓閥的安裝位置。高層內(nèi)減壓閥設(shè)計(jì)安裝的位置不妥，會(huì)出現(xiàn)減壓閥閥后壓力忽高忽低，管網(wǎng)壓力嚴(yán)重偏離允許范圍，伴隨毀壞淋浴器，水管爆裂和損壞用戶(hù)水表等事故發(fā)生；有時(shí)也會(huì)水流不暢，分區(qū)內(nèi)出現(xiàn)無(wú)規(guī)律的斷水現(xiàn)象，影響用戶(hù)用水。出現(xiàn)類(lèi)似事故，檢查整個(gè)減壓閥減壓分區(qū)給水系統(tǒng)，無(wú)疑點(diǎn)可找；拆卸減壓閥過(guò)濾器等元件并無(wú)異常；有些物業(yè)管理單位甚至懷疑減壓閥的技術(shù)性能，多次調(diào)換新的減壓閥，也不能解決問(wèn)題。這時(shí)可從檢查比例減壓閥設(shè)計(jì)安裝位置是否合理著手，認(rèn)真檢查管網(wǎng)系統(tǒng)是否存在等位倒虹管現(xiàn)象，即分區(qū)的輸出管路標(biāo)高相近。此類(lèi)情況在主、副樓同一屋頂水箱，下給水供水系統(tǒng)中很容易出現(xiàn)。發(fā)現(xiàn)這些問(wèn)題，可以考慮把比例減壓閥安裝位置提高一個(gè)層面(不能提得太高，必須顧全分區(qū)內(nèi)用水設(shè)備的承壓規(guī)范要求)；也可在主、副樓內(nèi)，分設(shè)兩組獨(dú)立的比例減壓閥給水系統(tǒng)。  192613 LFR-1/4-D-5M-O-MIDI G1/4 1600 l/min 0.5 ... 12 bar 5 µm

費(fèi)斯托減壓閥保障系統(tǒng)的管理巡視，要注意觀察減壓閥本身的工作動(dòng)態(tài)。閥前、閥后壓力數(shù)值接近，表明減壓閥本身已存在故障。即活塞式減壓閥的閥芯與閥體間的平面密封橡膠件損壞；薄膜式可調(diào)型減壓閥主閥膜片有裂痕和O型圈損壞，及導(dǎo)閥連通管堵塞，造成減壓閥減壓作用削弱或者失效。這對(duì)分區(qū)管網(wǎng)危害極大，特別是許多用水設(shè)備可能因超壓力而出現(xiàn)爆管，必須及時(shí)修復(fù)。比例式(活塞型)減壓閥閥體上的透吸氣小孔如出現(xiàn)滴漏不止，表明閥芯上幾檔O型密封圈已經(jīng)磨損，要更換密封件。但在修理拆裝減壓元件時(shí)，要謹(jǐn)慎細(xì)心，調(diào)換內(nèi)密封件；清理雜物時(shí)，應(yīng)因勢(shì)利導(dǎo)，不要用金屬棒、硬梗撬閥的活動(dòng)部位，使用木榔頭和木柄敲擊震動(dòng)，慢慢拆卸閥內(nèi)部件。修理完畢后重新安裝時(shí)，一定要和閥門(mén)上的流向指示保持*。  159584 LFR-1/2-D-MIDI G1/2 3400 l/min 0.5 ... 12 bar 40 µm

 德國(guó)ESTO減壓閥的減壓保障系統(tǒng)。無(wú)論選用比例式還是可調(diào)式減壓閥，其減壓比P1∶P2不宜選擇過(guò)大，一般應(yīng)控制在5∶1之內(nèi)。超過(guò)這個(gè)范圍易產(chǎn)生氣蝕現(xiàn)象，損壞閥件，產(chǎn)生嘯叫噪音。有些活塞式減壓閥，制造廠(chǎng)在其閥體上加工一個(gè)直徑1.5mm左右的小孔，其功能是讓閥芯運(yùn)動(dòng)時(shí)起到透吸氣作用，維護(hù)管理時(shí)應(yīng)注意千萬(wàn)不要將小孔塞住，否則影響減壓閥的正常運(yùn)行。192383 LFR-1-D-5M-O-DI-MAXI G1 6000 l/min 0.5 ... 12 bar 5 µm

費(fèi)斯托減壓閥在管道中起到一定的止回作用，為了防止水錘的危害，也可安裝小的膨脹水箱，防止損壞管道和閥門(mén)，過(guò)濾器必須安裝在減壓閥的進(jìn)水管前，而膨脹水箱必須安裝在減壓閥出水管后！
