拍門的安裝使用及注意事項：

1、拍門安裝可與法蘭連接，可與預埋板焊接，或二次澆注；

2、浮箱拍門在使用過程中，可通過向門頁密封腔體內(nèi)注水或放水的方法改變門頁的比重，以達到_開啟效果。

Installation, use, and precautions of flap gate: 1. The flap gate can be installed by connecting it to a flange, welding it to an embedded plate, or casting it in a secondary pouring process; 2. During the use of the buoyancy tank flap gate, the specific gravity of the gate leaf can be changed by injecting or draining water into the sealing chamber of the gate leaf, in order to achieve the opening effect.

3、拍門安裝后，門座與門頁間有3mm左右的間隙屬正常現(xiàn)象，當門頁承受_的反向壓力時，間隙會減少以致消失。

3. After the flap valve is installed, it is normal to have a gap of about 3mm between the valve seat and the valve leaf. When the valve leaf is subjected to a reverse pressure, the gap will decrease or even disappear.

4、拍門在使用過程中應保持其流道、密封圈不被石塊、樹枝等雜物卡堵，從而影響密封效果。

4. During use, the flapper valve should be kept free from blockage by debris such as stones and branches in its flow passage and sealing ring, which could affect the sealing effect.

5、經(jīng)常清理拍門下方沉砂池內(nèi)的積物，保持拍門支耳孔、鉸軸潤滑良好，開啟靈活。

5. Regularly clean the sediment in the sand basin below the flap valve to ensure that the support ear holes and hinge shafts of the flap valve are well lubricated and can be opened flexibly.
