一、根據(jù)流量特性選用閥門閥門啟閉件及閥門流道的形狀使閥門具備一定的流量特性。在選擇閥門時，必須考慮到這一點。1.截斷和接通介質(zhì)用閥門通常選擇流阻較小、流道為直通式的閥門。這類閥門有閘閥、截止閥、柱塞閥。向下閉合式閥門，由于流道曲折，流阻比其它閥門高，故較少選用。但是，在允許有較高流阻的場合，也可選用閉合式閥門。2.控制流量用的閥門通常選擇易于調(diào)節(jié)流量的閥門。如調(diào)節(jié)閥、節(jié)流閥、柱塞閥，因為它的閥座尺寸與啟閉件的行程之間成正比例關(guān)系。旋轉(zhuǎn)式（如旋塞閥、球閥、蝶閥）和撓曲閥體式（夾管閥、隔膜閥）閥門也可用于節(jié)流控制，但通常*在有限的閥門口徑范圍內(nèi)適用。在多數(shù)情況下，人們通常采用改變截止閥的閥瓣形狀后作節(jié)流用。應(yīng)該指出，用改變閘閥或截止閥的開啟高度來實現(xiàn)節(jié)流作用是極不合理的。因為，管路中介質(zhì)在節(jié)流狀態(tài)***速很高，密封面容易被沖刷磨損，失去切斷密封作用，同理，用節(jié)流閥作為切斷裝置也是不合理的。3，烏魯木齊進口閥門的價格.換向分流用閥門根據(jù)換向分流需要，這種閥可有三個或者更多的通道，適宜于選用旋塞閥和球閥。大部分換向分流用的閥門都選用這類閥門。在某些情況下，烏魯木齊進口閥門的價格，其它類型的閥門，烏魯木齊進口閥門的價格，用兩只或更多只適當(dāng)?shù)叵嗷ミB接起來。新疆黃銅絲扣截止閥批發(fā)。烏魯木齊進口閥門的價格</p><div

宜在波紋管減壓閥前加過濾器。在選用減壓閥時，應(yīng)注意不得超過減壓閥的減壓范圍。并保證在合理情況下使用。杠桿式減壓閥是采用重物或重力杠桿作敏感元件來帶動閥瓣運動的減壓閥。這種形式結(jié)構(gòu)簡單、耐用，但不精確。目前較少采用。⑵先導(dǎo)式先導(dǎo)式減壓閥是由主閥和導(dǎo)閥組成，出口壓力的變化通過導(dǎo)閥放大控制主閥動作的減壓閥。在此類閥中，導(dǎo)閥的作用是輔助控制主閥或者完全控制主閥。導(dǎo)閥本身可以是一個小型的直接作用式減壓閥。此類閥門精確的控制方式取決于它的特定結(jié)構(gòu)。而實質(zhì)上。導(dǎo)閥工作的目的是以維持預(yù)定壓力下的流量的方法來調(diào)節(jié)主閥的開啟量。先導(dǎo)式減壓閥的壓力控制精度非常精確，且結(jié)構(gòu)緊湊，對于功能相同的減壓閥來說，通常先導(dǎo)式比直接作用式結(jié)構(gòu)小得多。在這種形式中，導(dǎo)閥和主閥可以是整體的，也可以是適用于遠距離壓力信號控制的單獨的裝置，它還能作遠距離開關(guān)控制，也就是由控制中心控制的成套系統(tǒng)中的部件。另外，通過安裝適當(dāng)型式的導(dǎo)閥能夠獲得由溫度直接控制的設(shè)備。由于先導(dǎo)式減壓閥結(jié)構(gòu)復(fù)雜，因此需要經(jīng)常保養(yǎng)及清潔的工作條件。清潔工作條件常在閥入口處裝過濾器。</p><p> 同時與閥門的壓力、溫度及介質(zhì)的濃度等諸因素有著一定內(nèi)在聯(lián)系。閥門的流道面積與流速、流量有著直接關(guān)系，而流速與流量是相互依存的兩個量。當(dāng)流量一定時，流速大，流道面積便可小些；流速小，流道面積就可以大些。反之，流道面積大，其流速?。涣鞯烂娣e小，其流速大。介質(zhì)的流速大，閥門通徑可以小些，但阻力損失較大，閥門易損壞。流速大，對易燃易爆介質(zhì)會產(chǎn)生靜電效應(yīng)，造成危險；流速太小，效率低，不經(jīng)濟。對粘度大和易爆的介質(zhì)，應(yīng)取較小的流速。油及粘度大的液體隨粘度大小選擇流速，一般取～2m/s。一般情況***量是已知的，流速可由經(jīng)驗確定。各種介質(zhì)常用流速見表2-2。通過流速和流量可以計算閥門的公稱通徑。閥門通徑相同，其結(jié)構(gòu)型式不同，流體的阻力也不一樣。在相同條件下，閥門的阻力系數(shù)越大，流體通過閥門的流速、流量下降越多；閥門阻力系數(shù)越小，流體通過閥門的流速、流量下降越少。常見介質(zhì)的流速見表2-2。表2-2各種介質(zhì)常用的流速表液體名稱使用條件流速（m/s）液體名稱使用條件流速（m/s）飽和蒸汽DN＞200DN=200～100DN＜10030～4025～3515～30乙炔氣ρ＜（表壓）ρ＜（表壓）ρ＜。阿克蘇暗桿軟密封閘閥的價格。</p><div
