拍門工作原理很簡單，主要是為了攔截潮水，防止潮水過多帶來的負面影響。水位上升超過警戒線時，拍門會自動關閉來阻止潮水的流動，防止潮水的倒灌。水位低于水位警戒時，拍門會自動打開達到向外排水的目的，保持水位的一個平衡，所以拍門的工作原理主要分為兩個部分：關閉和打開。
The working principle of the flap door is very simple, mainly to intercept the tide and prevent the negative impact caused by excessive tide. When the water level rises above the warning line, the flap door will automatically close to prevent the flow of tide and prevent it from flowing back. When the water level is below the water level warning, the flap door will automatically open to achieve external drainage and maintain a balance of the water level. Therefore, the working principle of the flap door is mainly divided into two parts: closing and opening.
拍門關閉時:拍門的工作機制是，在沒家莊電動伸縮門 保定桌椅  保定水處理設備 河北機械加工  保定養老院  保定防水有外力作用的情況下，拍門的閥蓋處于一種平衡的狀態，當出現水流過多以至于沖擊壓力大時，拍門的閥門會發揮作用，以此來控制水流的進出。當排水的水位要高于規定的警戒線的時候，在出水口管道的拍門開始發揮作用，會自動進行關閉密封，防止潮水過高導致倒灌的現象發生。
When the flap door is closed: The working mechanism of the flap door is that, without external force, the valve cover of the flap door is in a balanced state. When there is too much water flow and the impact pressure is high, the valve of the flap door will play a role to control the inflow and outflow of water. When the water level of the drainage is above the specified warning line, the flap door of the water outlet pipeline will automatically close and seal to prevent the phenomenon of backflow caused by high tide.
拍門打開時：當潮水低于水位，拍門會自動打開，向外排水，以此來保持水位的一個平衡。通過拍門控制開關來控制這個水位的平衡和水流的穩定。
When the flap door is opened: When the tide is below the water level, the flap door will automatically open and drain outward to maintain a balance of the water level. Control the balance of the water level and the stability of the water flow through the flap door control switch.
