| 拍门工作原理 Working principle of flap door 拍门由阀座(阀体)、阀板、密封圈、铰链四部分构成。仅用于单向水流的圆形和方形出水口，结构严密，工作可靠，无需人力操作启闭力来自水源压力，当拍门内的水压大于拍门外侧压力则开启；反之则关闭。 The flap door consists of valve seat (valve body), valve plate, sealing ring and hinge. Circular and square water outlets are only used for one-way flow. They are compact in structure and reliable in operation. The opening and closing force comes from the water source pressure. When the water pressure inside the flap door is greater than the pressure outside the flap door, it will open; otherwise, it will be closed. 适用介质：水，河水，江水，海水，生活，工业污水 Applicable media: water, river water, river water, sea water, domestic and industrial sewage 适用范围 ：适用于水利系统、市政污水、城市防洪排涝、污水处理厂、自来水厂等。 Scope of application: suitable for water conservancy system, municipal sewage, urban flood control and drainage, sewage treatment plant, water plant, etc. |
