style="text-indent:25px;font-size:14px;">要選擇管道系統(tǒng)適合安裝的閥門產(chǎn)品，首先應(yīng)了解閥門的特性；其次應(yīng)掌握選擇閥門的步驟和依據(jù)；再者應(yīng)遵循選擇閥門的原則。關(guān)斷閥：這類閥門是起開閉作用的。常設(shè)于冷、熱源進(jìn)、出口，設(shè)備進(jìn)、出口，管路分支線（包括立管）上，也可用作放水閥和放氣閥。常見的關(guān)斷閥有閘閥、截止閥、球閥和蝶閥等。流道為直通式的閥門，其流阻較小，通常選擇作為截止和開放介質(zhì)用的閥門。向下閉合式閥門（截止閥、柱塞閥）由于其流道曲折，流阻比其他閥門高，故較少選用。在允許有較高流阻的場合，可選用閉合式閥門。</p><p

style="text-indent:25px;font-size:14px;">閘閥是作為截止介質(zhì)使用，在全開時(shí)整個(gè)流通直通，此時(shí)介質(zhì)運(yùn)行的壓力損失小。閘閥通常適用于不需要經(jīng)常啟閉，而且保持閘板全開或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。閥門是在流體系統(tǒng)中，用來控制流體的方向、壓力、流量的裝置，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。閥門在出廠前應(yīng)進(jìn)行以下的檢測：①閥門在開啟狀況下，閥體應(yīng)承受閥門工壓值二倍的內(nèi)壓檢測；②閥門在關(guān)閉狀況下，兩側(cè)分別承受11倍閥門工壓值，無滲漏；但金屬密封的蝶閥，滲漏值亦不大于相關(guān)要求。</p><p
