不銹鋼拍門工作原理
拍門由閥座(閥體)、閥板、密封圈、鉸鏈四部分構成。僅用于單向水流的圓形和方形出水口,結構嚴密,工作可靠,無需人力操作啟閉力來自水源壓力,當拍門內的水壓大于拍門外側壓力則開啟;反之則關閉。
適用介質:水,河水,江水,海水,生活,工業污水
適用范圍 :適用于水利系統、市政污水、城市防洪排澇、污水處理廠、自來水廠等。
拍門的結構特點:
不銹鋼拍門具有流道正向單向開啟和反向關閉的作用。鑄鐵拍門的閥蓋借助于自身配重的平衡作用,在水流的作用下使門頁自動開啟或關閉,或稍加外力作用使門頁開啟或關閉;不銹鋼拍門廠家蓋上設有拉環,拉動拉環此蓋的開啟角度應大于60度,無卡阻現象,開關應自由靈活,當鑄鐵拍門部分泡在水中,管道內部壓力較大,反向壓力較小時,不銹鋼鑄鐵拍門廠家允許部分泄漏量,當河道水壓增大時,鑄鐵拍門將自動關閉密封。
