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(jìn)行檢查，確認(rèn)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(jìn)行排污泄壓，以利于注脂工作的順利進(jìn)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(jìn)行清通處理。新疆烏市閘閥直銷烏魯木齊市液化氣閥門廠家推薦。</p><div

蝴蝶閥(Butterfly valve)——由閥殼和閥體構(gòu)成。具有可旋轉(zhuǎn)的圓盤形或雙平板形的活門，用以截斷水流的閥門，其轉(zhuǎn)動軸線與水流方向垂直，當(dāng)閥體平面處于與水流方向垂直狀態(tài)時，閥門關(guān)閉。 </p> <p> 1)閥體：作用是過水通道的一部分，水流由其中通過，支撐活門重量，承受操作力和力矩，傳遞水壓力。2)活門：作用是關(guān)閉時截斷水流，要求有足夠的強(qiáng)度，開啟時在水流中心水力損失小，有良好的水力特性。3)軸及軸承：支持活門的重量。4)鎖錠：蝶閥的活門在全關(guān)或全開時需要鎖錠。5)旁通閥、旁通管：主閥開啟時減少力矩，消除在動水下的振動。6)空氣閥：關(guān)閉時向蝶閥后補(bǔ)氣，防止鋼管因產(chǎn)生真空而遭致破壞，開啟前向閥后充水時排氣。該閥有一個空心浮筒懸掛在導(dǎo)向活塞之下，空心浮筒在蝸殼或管中的水面上。此外，通氣孔于大氣相通，以便對蝸殼和管道進(jìn)行補(bǔ)氣或排氣。當(dāng)管道和蝸殼充滿水時，浮筒上浮至極限位置，蝸殼和管道于大氣隔絕，以防止水流外溢。烏魯木齊市高壓油田閥門公司推薦。</p><div
