style="text-indent:25px">按閥芯來分，可分為橡膠芯、陶瓷閥芯和不銹鋼閥芯、軸滾式閥芯等幾種。使用橡膠芯的水**多為螺旋式開啟的鑄鐵水**，現(xiàn)在已經(jīng)基本被淘汰；陶瓷閥芯水**是近幾年出現(xiàn)的，質(zhì)量較好，現(xiàn)在比較普遍；不銹鋼閥芯是近期才出現(xiàn)的，更適合水質(zhì)差的地區(qū)。陶瓷片閥芯的優(yōu)點(diǎn)是價(jià)格低，對水質(zhì)污染較小，但陶瓷質(zhì)地較脆，容易破裂。不銹鋼球閥是有較高科技含量的一種**閥芯，特別適合水質(zhì)不良的地區(qū)。因?yàn)樗皇芩镫s質(zhì)的影響，不會因此而縮短使用壽命，而且鋼球閥芯的把手在調(diào)節(jié)水溫的區(qū)域內(nèi)有較大的角度，可以準(zhǔn)確地控制水溫，確保熱水迅速準(zhǔn)確地流出，起到節(jié)約能源的功效。</p><p 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。閥芯閥板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)的閥芯可用于帶懸浮固體顆粒的介質(zhì)。</p><div
