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行補氣或排氣。當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。烏魯木齊市水利控制閥廠家推薦。新疆烏市排氣閥哪家好</p><p
