一、根據(jù)流量特性選用閥門(mén)閥門(mén)啟閉件及閥門(mén)流道的形狀使閥門(mén)具備一定的流量特性。在選擇閥門(mén)時(shí)，必須考慮到這一點(diǎn)。1.截?cái)嗪徒油ń橘|(zhì)用閥門(mén)通常選擇流阻較小、流道為直通式的閥門(mén)。這類(lèi)閥門(mén)有閘閥、截止閥、柱塞閥。向下閉合式閥門(mén)，由于流道曲折，流阻比其它閥門(mén)高，故較少選用。但是，在允許有較高流阻的場(chǎng)合，也可選用閉合式閥門(mén)。2.控制流量用的閥門(mén)通常選擇易于調(diào)節(jié)流量的閥門(mén)。如調(diào)節(jié)閥、節(jié)流閥、柱塞閥，因?yàn)樗拈y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(mén)也可用于節(jié)流控制，但通常*在有限的閥門(mén)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(kāi)啟高度來(lái)實(shí)現(xiàn)節(jié)流作用是極不合理的。因?yàn)椋苈分薪橘|(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.換向分流用閥門(mén)根據(jù)換向分流需要，這種閥可有三個(gè)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(mén)都選用這類(lèi)閥門(mén)。在某些情況下，其它類(lèi)型的閥門(mén)，用兩只或更多只適當(dāng)?shù)叵嗷ミB接起來(lái)。</p><p>
