詳細介紹
FESTO減壓閥是氣動調節閥的一個*配件，主要作用是將氣源的壓力減壓并穩定到一個定值，以便于調節閥能夠獲得穩定的氣源動力用于調節控制。 按結構形式可分為薄膜式、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。 526273 LFR-M5-D-7-5M-MICRO M5 110 l/min 0.5 ... 7 bar 5 µm

FESTO比例式減壓閥的安裝位置。高層內減壓閥設計安裝的位置不妥，會出現減壓閥閥后壓力忽高忽低，管網壓力嚴重偏離允許范圍，伴隨毀壞淋浴器，水管爆裂和損壞用戶水表等事故發生；有時也會水流不暢，分區內出現無規律的斷水現象，影響用戶用水。出現類似事故，檢查整個減壓閥減壓分區給水系統，無疑點可找；拆卸減壓閥過濾器等元件并無異常；有些物業管理單位甚至懷疑減壓閥的技術性能，多次調換新的減壓閥，也不能解決問題。這時可從檢查比例減壓閥設計安裝位置是否合理著手，認真檢查管網系統是否存在等位倒虹管現象，即分區的輸出管路標高相近。此類情況在主、副樓同一屋頂水箱，下給水供水系統中很容易出現。發現這些問題，可以考慮把比例減壓閥安裝位置提高一個層面(不能提得太高，必須顧全分區內用水設備的承壓規范要求)；也可在主、副樓內，分設兩組獨立的比例減壓閥給水系統。 192613 LFR-1/4-D-5M-O-MIDI G1/4 1600 l/min 0.5 ... 12 bar 5 µm

費斯托減壓閥保障系統的管理巡視，要注意觀察減壓閥本身的工作動態。閥前、閥后壓力數值接近，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；薄膜式可調型減壓閥主閥膜片有裂痕和O型圈損壞，及導閥連通管堵塞，造成減壓閥減壓作用削弱或者失效。這對分區管網危害極大，特別是許多用水設備可能因超壓力而出現爆管，必須及時修復。比例式(活塞型)減壓閥閥體上的透吸氣小孔如出現滴漏不止，表明閥芯上幾檔O型密封圈已經磨損，要更換密封件。但在修理拆裝減壓元件時，要謹慎細心，調換內密封件；清理雜物時，應因勢利導，不要用金屬棒、硬梗撬閥的活動部位，使用木榔頭和木柄敲擊震動，慢慢拆卸閥內部件。修理完畢后重新安裝時，一定要和閥門上的流向指示保持*。 159584 LFR-1/2-D-MIDI G1/2 3400 l/min 0.5 ... 12 bar 40 µm

德國ESTO減壓閥的減壓保障系統。無論選用比例式還是可調式減壓閥，其減壓比P1∶P2不宜選擇過大，一般應控制在5∶1之內。超過這個范圍易產生氣蝕現象，損壞閥件，產生嘯叫噪音。有些活塞式減壓閥，制造廠在其閥體上加工一個直徑1.5mm左右的小孔，其功能是讓閥芯運動時起到透吸氣作用，維護管理時應注意千萬不要將小孔塞住，否則影響減壓閥的正常運行。192383 LFR-1-D-5M-O-DI-MAXI G1 6000 l/min 0.5 ... 12 bar 5 µm

費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，過濾器必須安裝在減壓閥的進水管前，而膨脹水箱必須安裝在減壓閥出水管后！
