style="text-indent:25px">先導(dǎo)式減壓閥當(dāng)減壓閥的輸出壓力較高或通徑較大時(shí)，用調(diào)壓彈簧直接調(diào)壓，則彈簧剛度必然過大，流量變化時(shí)，輸出壓力波動(dòng)較大，閥的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點(diǎn)，可采用先導(dǎo)式減壓閥。先導(dǎo)式減壓閥的工作原理與直動(dòng)式的基本相同。先導(dǎo)式減壓閥所用的調(diào)壓氣體，是由小型的直動(dòng)式減壓閥供給的。若把小型直動(dòng)式減壓閥裝在閥體內(nèi)部，則稱為內(nèi)部先導(dǎo)式減壓閥；若將小型直動(dòng)式減壓閥裝在主閥體外部，則稱為外部先導(dǎo)式減壓閥。與直動(dòng)式減壓閥相比，增加了由噴嘴、擋板、固定節(jié)流孔及氣室所組成的噴嘴擋板放大環(huán)節(jié)。當(dāng)噴嘴與擋板之間的距離發(fā)生微小變化時(shí)，就會(huì)使壓力發(fā)生根明顯的變化，從而引起膜片有較大的位移，去控制閥芯的上下移動(dòng)，使進(jìn)氣閥口開大或關(guān)小、提高了對(duì)閥芯控制的靈敏度，即提高了穩(wěn)壓精度。</p><p style="text-indent:25px">加強(qiáng)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。蝶閥在完全開啟時(shí)，具有較小的流阻。當(dāng)開啟在大約15°~70°之間時(shí)。</p><div
