拍門的安裝使用及注意事項：
Installation, use, and precautions for tapping doors:
1、拍門安裝可與法蘭連接，可與預埋板焊接，或二次澆注；
1. The installation of the door can be connected to the flange, welded to the embedded plate, or poured twice;
2、浮箱拍門在使用過程中，可通過向門頁密封腔體內注水或放水的方法改變門頁的比重，以達到_開啟效果。
2. During the use of the floating box flap door, the specific gravity of the door leaf can be changed by injecting or draining water into the sealing chamber of the door leaf 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象，當門頁承受_的反向壓力時，間隙會減少以致消失。
3. After installing the door, it is normal for there to be a gap of about 3mm between the door seat and the door leaf. When the door leaf is subjected to reverse pressure, the gap will decrease and 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 door should keep its flow channel and sealing ring unobstructed by debris such as stones and branches, which may affect the sealing effect.
5、經常清理拍門下方沉砂池內的積物，保持拍門支耳孔、鉸軸潤滑良好，開啟靈活。
5. Regularly clean the sediment in the sedimentation tank below the door, keep the ear holes and hinge shafts of the door well lubricated, and ensure flexible opening.
