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，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，輸出壓力波動較大，閥的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點，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，是由小型的直動式減壓閥供給的。若把小型直動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，就會使壓力發(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，使進氣閥口開大或關(guān)小、提高了對閥芯控制的靈敏度，即提高了穩(wěn)壓精度。鋁合金手動蝶閥制造商哪家好減壓閥的每一檔彈簧只在一定的出口壓力范圍內(nèi)適用，超出范圍應(yīng)更換彈簧；</p><div

style="text-indent:25px">減壓閥在修理拆裝減壓元件時，要謹(jǐn)慎細(xì)心，調(diào)換內(nèi)密封件；清理雜物時，應(yīng)因勢利導(dǎo)，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(nèi)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一致。如果需要將減壓閥安裝在熱水系統(tǒng)時，您必須在減壓閥和膨脹水箱之間安裝止回閥。這樣既可以讓膨脹水箱吸收由于熱膨脹而增加的水的體積，又可以防止熱水回流或壓力波動對減壓閥的影響，確保減壓閥長期正常工作。金屬密封蝶閥產(chǎn)品不適合裝置于管路結(jié)尾。燃?xì)鉁p壓閥定制費用</p><p
