style="text-indent:25px">先導式液壓快速接頭當液壓快速接頭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，接頭的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點，可采用先導式液壓快速接頭。先導式液壓快速接頭的工作原理與直動式的基本相同。先導式液壓快速接頭所用的調(diào)壓氣體，是由小型的直動式液壓快速接頭供給的。若把小型直動式液壓快速接頭裝在接頭體內(nèi)部，則稱為內(nèi)部先導式液壓快速接頭；若將小型直動式液壓快速接頭裝在主接頭體外部，則稱為外部先導式液壓快速接頭。與直動式液壓快速接頭相比，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，去控制接頭芯的上下移動，使進氣接頭口開大或關(guān)小、提高了對接頭芯控制的靈敏度，即提高了穩(wěn)壓精度。浙江電纜卷筒液壓工具</p></p><br
