rexroth疊加式雙單向節(jié)流閥設計安裝的位置不妥，會出現(xiàn)減壓閥閥后壓力忽高忽低，管網(wǎng)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(fā)生；有時也會水流不暢，分區(qū)內(nèi)出現(xiàn)無規(guī)律的斷水現(xiàn)象，影響用戶用水。

Rexroth力士樂疊加式雙單向節(jié)流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(qū)管網(wǎng)危害極大，特別是許多用水設備可能因超壓力而出現(xiàn)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(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，要謹慎細心，調換內(nèi)密封件；清理雜物時，應因勢利導，不要用金屬棒、硬梗撬閥  減壓閥的活動部位，使用木榔頭和木柄敲擊震動，慢慢拆卸閥內(nèi)部件。
