2、啟閉時較省力。是與截止閥相比而言，因為無論是開或閉，閘板運動方向均與介質(zhì)流動方向相垂直。 3、高度大，啟閉時間長。閘板的啟閉行程較大，升降是通過螺桿進行的。 4、水錘現(xiàn)象不易產(chǎn)生。原因是關(guān)閉時間長。 5、介質(zhì)可向兩側(cè)任意方向流動，易于安裝。閘閥通道兩側(cè)是對稱的。 6、結(jié)構(gòu)長度(系殼體兩連接端面之間的距離)較小。 7、形體簡單，結(jié)構(gòu)長度短，制造工藝性好，適用范圍廣。 8、結(jié)構(gòu)緊湊，閥門剛性好，通道流暢，流阻數(shù)小，密封面采用不銹鋼和硬質(zhì)合金，使用壽命長，采用PTFE填料，密封可靠，操作輕便靈活。烏魯木齊市高壓油田閥門供應(yīng)商。新疆烏市阻火器閥公司推薦</p><p

第四、閥門注脂時，常忽略注脂效果問題。注脂操作中壓力、注脂量、開關(guān)位都正常。但為確保閥門注脂效果，有時需開啟或關(guān)閉閥門，對潤滑效果進行檢查，確認閥門閥球或閘板表面潤滑均勻。第五、注脂時，要注意閥體排污和絲堵泄壓問題。閥門打壓試驗后，密封腔閥腔內(nèi)氣體和水分因環(huán)境溫度升高而升壓，注脂時要先進行排污泄壓，以利于注脂工作的順利進行。注脂后密封腔內(nèi)的空氣和水分被充分置換出來。及時泄掉閥腔壓力，也保障了閥門使用安全。注脂結(jié)束后，一定要擰緊排污和泄壓絲堵，以防意外發(fā)生。第六、注脂時，要注意出脂均勻的問題。正常注脂時，距離注脂口**近的出脂孔先出脂，然后到低點，***是高點，逐次出脂。如果不按規(guī)律或不出脂，證明存在堵塞，及時進行清通處理。新疆烏市針型閥代理</p><p
