style="text-indent:25px">安裝前應空試蝶閥，啟閉應靈活，啟閉位置與指針指示位置相符合。手動操作順時針為關，逆時針為開，指針指示到位后不準再加力啟閉閥門。閥門做壓力試驗時，不準用單法蘭進行安裝試壓，必須采用雙法蘭安裝試壓。其試驗壓力應符合GB/T13927-92標準規(guī)定。緊固螺栓時應對稱交替進行緊固，不準依次單獨緊固。限位螺釘出廠前，已經調好，不準輕易調整。若配置驅動裝置為電動、氣動請閱配套驅動裝置說明書。電動蝶閥出廠時已將控制機構的啟閉行程調好。為防止電源接通時方向搞錯，用戶在一次接通電源前要先手動開啟至半開位置，再按點動開關，檢查指示盤方向與閥門開啟方向一致即可。</p><p style="text-indent:25px">蝶閥是一種自動降低管路工作壓力的專門裝置，它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質主要是水。蝶閥普遍用于高層建筑、城市給水管網水壓過高的區(qū)域、礦井及其他場合，以保證給水系統(tǒng)中各用水點獲得適當?shù)姆账畨汉土髁?。鑒于水的漏失率和浪費程度幾乎同給水系統(tǒng)的水壓大小成正比，因此蝶閥具有改善系統(tǒng)運行工況和潛在節(jié)水作用，據(jù)統(tǒng)計其節(jié)水效果約為30%。蝶閥的構造類型很多，以往常見的有薄膜式、內彈簧活塞式等。蝶閥的基本作用原理是靠閥內流道對水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側的進出口水壓差自動調節(jié)。蝶閥在低壓下，可以實現(xiàn)良好的密封。</p><div
