      不銹鋼閘閥的特點(diǎn)是當(dāng)閥門全開時(shí),流體具有平滑勻稱通道,并沒(méi)有可以積累固體或沉積物的溝槽或裂縫。它們是平行閘閥的衍生,但是具備了其他的為更苛刻工況應(yīng)用的特點(diǎn)。由于流道的全通口平滑,流體摩擦損失都非常低,因此CV值高。這種平滑全通徑的閥門不能進(jìn)行流量調(diào)節(jié),不能形成很高的速度。管道閘閥不推薦用于流量調(diào)節(jié)或節(jié)流。但適合固體介質(zhì)的輸送。這些閥門可以機(jī)械清理及“清管”。管道不銹鋼閘閥也被稱作“通孔閘閥”、“管線閥”。
      不銹鋼閘閥的啟閉件是閘板,閘板的運(yùn)動(dòng)方向與流體方向相垂直,閘閥只能作全開和全關(guān) , 不能作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面 , 最常用的模式閘板閥的兩個(gè)密封面形成楔形、楔形角隨閥門參數(shù)而異 , 通常為 50, 介質(zhì)溫度不高時(shí)為 2°52‘ 。楔式閘閥的閘板可以做成一個(gè)整 體,叫做剛性閘板;也可以做成能產(chǎn)生微量變形的閘板 , 以改善其工藝性 , 彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差 , 這種閘板叫做彈性閘板。不銹鋼閘閥材質(zhì)分為304不銹鋼閘閥,316不銹鋼閘閥,321不銹鋼閘閥。表示方法為:Z41W-16P。
