（1）截?cái)囝?lèi)：如閘閥、截止閥、旋塞閥、球閥、蝶閥、針型閥、隔膜閥等。截?cái)囝?lèi)閥門(mén)又稱(chēng)閉路閥，截止閥，其作用是接通或截?cái)喙苈分械慕橘|(zhì)。 </p> <p> (2) 止回類(lèi)：如止回閥，止回閥又稱(chēng)單向閥或逆止閥，止回閥屬于一種自動(dòng)閥門(mén)，其作用是防止管路中的介質(zhì)倒流、防止泵及驅(qū)動(dòng)電機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄漏。水泵吸水關(guān)的底閥也屬于止回閥類(lèi)。 </p> <p> (3) 安全類(lèi)：如安全閥、防爆閥等。安全閥的作用是防止管路或裝置中的介質(zhì)壓力超過(guò)規(guī)定數(shù)值，從而達(dá)到安全保護(hù)的目的。 </p> <p> (4) 調(diào)節(jié)類(lèi)：如調(diào)節(jié)閥、節(jié)流閥和減壓閥，其作用是調(diào)節(jié)介質(zhì)的壓力、流量等參數(shù)。 </p> <p> (5) 分流類(lèi)：如分配閥、三通閥、疏水閥。其作用是分配、分離或混合管路中的介質(zhì)。 </p> <p> (6）特殊用途類(lèi)：如清管閥、放空閥、排污閥、排氣閥、過(guò)濾器等。排氣閥是管道系統(tǒng)中必不可少的輔助元件，廣泛應(yīng)用于鍋爐、空調(diào)、石油天然氣、給排水管道中。往往安裝在制高點(diǎn)或彎頭等處，排除管道中多余氣體、提高管道路使用效率及降低能耗。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東軟密封閘閥門(mén)零售" src="http://tyunfile.71360.com/UpLoadFile/sdkgfm/2019/11/637087462913012624/6370874629130126246683944.jpg"></div><p> 既按原理、作用又按結(jié)構(gòu)劃分，是目前國(guó)際、國(guó)內(nèi)**常用的分類(lèi)方法。一般分閘閥、截止閥、節(jié)流閥、儀表閥、柱塞閥、隔膜閥、旋塞閥、球閥、蝶閥、止回閥、減壓閥安全閥、疏水閥、調(diào)節(jié)閥、底閥、過(guò)濾器、排污閥等。 </p> <p> 由于閥門(mén)的用途是非常廣的，因此它起的作用也是很大的。例如：在發(fā)電廠中閥門(mén)能夠控制鍋爐和汽輪機(jī)的運(yùn)轉(zhuǎn)；在石油、化工生產(chǎn)中，閥門(mén)同樣也起著控制全部生產(chǎn)設(shè)備和工藝流程的正常運(yùn)轉(zhuǎn)。在其它部門(mén)也是這樣。盡管如此，閥門(mén)同其它產(chǎn)品比較往往被人們忽視。例如：在安裝機(jī)器設(shè)備時(shí)，人們往往把重點(diǎn)放在主要機(jī)器設(shè)備方面，卻忽視了閥門(mén)。這樣會(huì)使整個(gè)生產(chǎn)效率降低或停產(chǎn)、或造成種種其它事件發(fā)生。因此，對(duì)閥門(mén)的選用、安裝、使用等都必須進(jìn)行認(rèn)真負(fù)責(zé)的工作。
