一 閥門的定義：
“閥”的定義是在流體系統(tǒng)中，用來控制流體的方向、壓力、流量的裝置。閥門是使配管和設(shè)備內(nèi)的介質(zhì)（液體、氣體、粉末）流動(dòng)或停止、并能控制其流量的裝置。
二 根據(jù)啟閉閥門的作用不同，閥門的分類方法很多，這里介紹下列幾種。
1. 按作用和用途分類
（1） 截?cái)嚅y：截?cái)嚅y又稱閉路閥，其作用是接通或截?cái)喙苈分械慕橘|(zhì)。截?cái)嚅y類包括閘閥、截止閥、旋塞閥、球閥、蝶閥和隔膜等。
（2） 止回閥：止回閥又稱單向閥或逆止閥，其作用是防止管路中的介質(zhì)倒流。水泵吸水關(guān)的底閥也屬于止回閥類。
（3） 安全閥：安全閥類的作用是防止管路或裝置中的介質(zhì)壓力超過規(guī)定數(shù)值，從而達(dá)到安全保護(hù)的目的。
（4） 調(diào)節(jié)閥：調(diào)節(jié)閥類包括調(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、流量等叁數(shù)。
（5） 分流閥：分流閥類包括各種分配閥和疏水閥等，其作用是分配、分離或混合管路中的介質(zhì)。
2. 按公稱壓力分類
（1） 真空閥：指工作壓力低于標(biāo)準(zhǔn)大氣壓的閥門。
（2） 低壓閥：指公稱壓力PN ≤1.6Mpa 的閥門。
（3） 中壓閥：指公稱壓力PN 為2.5、4.0、6.4Mpa的閥門。
（4） 高壓閥：指工稱壓力PN 為10～80Mpa的閥門。
（5） 超高壓閥：指公稱壓力 PN≥100Mpa的閥門。
3. 按工作溫度分類
（1） 超低溫閥：用于介質(zhì)工作溫度 t<－100℃的閥門。
（2） 低溫閥：用于介質(zhì)工作溫度－100℃≤t≤－40℃的閥門。
（3） 常溫閥：用于介質(zhì)工作溫度－40℃≤t≤120℃的閥門。
（4） 中溫閥：用于介質(zhì)工作溫度120℃
（5） 高溫閥：用于介質(zhì)工作溫度t>450℃的閥門。
4. 按驅(qū)動(dòng)方式分類
（1） 自動(dòng)閥是指不需要外力驅(qū)動(dòng)，而是依靠介質(zhì)自身的能量來使閥門動(dòng)作的閥門。如安全閥、減壓閥、疏水閥、止回閥、自動(dòng)調(diào)節(jié)閥等。
（2） 動(dòng)力驅(qū)動(dòng)閥：動(dòng)力驅(qū)動(dòng)閥可以利用各種動(dòng)力源進(jìn)行驅(qū)動(dòng)。
電動(dòng)閥：借助電力驅(qū)動(dòng)的閥門。
氣動(dòng)閥：借助壓縮空氣驅(qū)動(dòng)的閥門。
液動(dòng)閥：借助油等液體壓力驅(qū)動(dòng)的閥門。
此外還有以上幾種驅(qū)動(dòng)方式的組合，如氣-電動(dòng)閥等。
（3） 手動(dòng)閥：手動(dòng)閥借助手輪、手柄、杠桿、鏈輪，由人力來操縱閥門動(dòng)作。當(dāng)閥門啟閉力矩較大時(shí)，可在手輪和閥桿之間設(shè)置此輪或蝸輪減速器。必要時(shí)，也可以利用萬向接頭及傳動(dòng)軸進(jìn)行遠(yuǎn)距離操作。
綜上所述，閥門分類方法是很多的，但主要是按其在管路中所起的作用進(jìn)行分類。工業(yè)和民用工程中的通用閥門可分成11類，即閘閥、截止閥、旋塞閥、球閥、蝶閥、 隔 膜閥、止回閥、節(jié)流閥、安全閥、減壓閥和疏水閥。其他特殊閥門，如儀表用閥、液壓控制管路系統(tǒng)用閥，各種化工機(jī)械設(shè)備本體用閥等，均不在本書介紹范圍以內(nèi)。
5. 按公稱通徑分類
（1）小通徑閥門：公稱通徑DN≤40mm的閥門。
（2）中通徑閥門：公稱通徑DN為50～300mm的閥門。
（3）大通徑閥門：公稱閥門DN為350～1200mm的閥門。
（4）特大通徑閥門：公稱通徑DN≥1400mm的閥門。
6. 按結(jié)構(gòu)特征分類
（1）截門形：啟閉件（閥瓣）由閥桿帶動(dòng)沿著閥座中心線作升降運(yùn)動(dòng)；
（2）旋塞形：啟閉件（閘閥）由閥桿帶動(dòng)沿著垂直于閥座中心線作升降運(yùn)動(dòng)；
（3）旋塞閥：啟閉件（錐塞或球） 圍繞自身中心線旋轉(zhuǎn)；
（4）旋啟閥：啟閉件（閥瓣） 圍繞座外的軸旋轉(zhuǎn)；
（5）蝶行：啟閉件（圓盤） 圍繞閥座內(nèi)的固定軸旋轉(zhuǎn)；
（6）滑閥行：啟閉件在垂直于通道的方向滑動(dòng)。
7. 按連接方法分類
（1）螺紋連接閥門：閥體帶有內(nèi)螺紋或外螺紋，與管道螺紋連接。
（2）法蘭連接閥門：閥體帶有法蘭，與管道法蘭連接。
（3）焊接連接閥門：閥體帶有焊接坡口，與管道焊接連接。
（4）卡箍連接閥門：閥體帶有夾口，與管道夾箍連接。
（5）卡套連接閥門：與管道采用卡套連接。
（6）對夾連接閥門：用螺栓直接將閥門及兩頭管道穿夾在一起的連接形式。
8. 按閥體材料分類
（1）金屬材料閥門：其閥體等零件由金屬材料制成。如鑄鐵閥、碳鋼閥、合金鋼閥、銅合金閥、鋁合金閥、鉛合金閥、鈦合金閥、蒙乃爾合金閥等。
（2）非金屬材料閥門：其閥體等零件由非金屬材料制成。如塑料閥、陶 閥、搪 閥、玻璃鋼閥等。
（3）金屬閥體襯里閥門：閥體外形為金屬，內(nèi)部凡與介質(zhì)接觸的主要表面均為襯里，如襯膠閥、 襯塑料閥、襯陶閥等。
