style="text-indent:25px">液壓閥的閥芯主要有滑閥和錐閥兩種。具有圓柱狀軸肩的閥芯，沿軸向移動(dòng)以接通或斷開油路的圓柱滑閥通常指滑閥。通過閥口開度的變化，其流量也隨之變化，使流量得到調(diào)節(jié)。通過改變錐閥閥芯與閥座之間的縫隙，以接通或斷開油路的閥，稱為錐閥。錐閥能完全切斷油路，對(duì)油液中雜質(zhì)污染的敏感性小，結(jié)構(gòu)簡單，制造容易。所以錐閥與滑閥為液壓閥的主要結(jié)構(gòu)之一。因?yàn)閮煞N結(jié)構(gòu)不同，因此加工的方法既有相同點(diǎn)，也有不同點(diǎn)。一般都是由專業(yè)生產(chǎn)廠家制造。江蘇閥芯加工閥芯是一個(gè)**質(zhì)量評(píng)價(jià)的重要依據(jù)，閥芯的質(zhì)量甚至可以說是影響**使用壽命的決定性因素。</p><div
