密封面易損傷啟閉時閘板與閥座相接觸的兩密封而之間有相對摩擦，易損傷，影響密封件能與使用壽命，維修比較困難。 2 啟閉時間長，高度大由于閘閥啟閉時須全開或全關(guān)，閘板行程大，開啟用要一定的空間，外形尺寸高，安裝所需空間較大。 3 結(jié)構(gòu)復(fù)雜閘閥一般都有兩個密封面，給加工、研磨和維修增加一些，困難零件較多，制造與維修較困難，成本比截止閥高。</p><p

楔式閘板式閘閥又可分為:單閘極式、雙閘板式和彈性閘板式;平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。鉻鉬鋼閘閥的密封面采用不銹鋼和硬質(zhì)合金，使用壽命長。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
