當減壓閥的輸出壓力較高或流量較大時，用調(diào)壓彈簧直接調(diào)壓，則彈簧剛度必然大，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。為克服這些缺點可采用先導(dǎo)式減壓閥。圖3—33所示為先導(dǎo)式減壓閥的結(jié)構(gòu)和工作原理圖，圖中1、14是主閥的閥芯和彈簧。6、8足先導(dǎo)閥閥芯和彈簧，圖示主閥芯與閥套沉割槽之間形成的減壓口處于全開狀態(tài)。軸承保持器的損壞現(xiàn)象不是很明顯，在通常情況下并不容易判斷。軸承的震動，速度超出設(shè)計要求，磨損，異物卡死與歪斜等都是保持器損壞的主要原因。就以上所說的情況來分析分析：震動當軸承處于震動的狀況下，軸承內(nèi)部的力量可能導(dǎo)致保持器的出現(xiàn)疲勞裂痕。漸漸的，此裂痕會使保持器破裂。為預(yù)防此現(xiàn)象，可采用配備特殊的保持器的軸承。速度超出設(shè)計要求若軸承是以超出保持材料所能承受的速度運轉(zhuǎn)，慣性力會導(dǎo)致保持器破裂。
