principle Duckbill valve made of elastic neoprene and artificial fiber with a special processing, shaped like a duckbill, called duckbill valve. In internal pressure, the duckbill exports in itself under the action of elasticity closure; increased gradually with the internal pressure, duckbill exports gradually increased, the liquid to discharge at high flow rates. standard The earliest design duckbill valve, to matched with the national standards, the provisions of the 800 the following caliber duckbill valve flange standard reference GB 1.0MPa bolt hole center distance and diameter of flange, pipe diameter of more than 800 (inclusive), according to GB 0.6MPa bolt hole center distance and diameter of flange. effect Editor Rubber duckbill valve can prevent floods and sewage intrusion into the sewers and streets in the basement, to avoid heavy losses and prevent the rise of the water level and flood intrusion into the sewage treatment plant, drainage pumping station; to prevent sewage or there is the smell of the odor of fluid diffusion, and be ready for the drainage; in the rainy season, to prevent urban river flood from the sewer and pour into the streets; quality is better than the door, overcome the shoot, such as door is not tightly closed and some defects.
principle
鴨嘴閥由彈性氯丁橡膠加人造纖維經特殊加工而成，形狀類似鴨嘴，故稱鴨嘴閥。在內(nei) 部無壓力情況下，鴨嘴出口在本身彈性作用下合攏；隨內(nei) 部壓力逐漸增加，鴨嘴出口逐漸增大，保持液體(ti) 能在高流速下排出。

最早設計出鴨嘴閥時，為(wei) 了與(yu) 國家標準相配合，規定了800以下口徑鴨嘴閥的法蘭(lan) 標準參照國標1.0Mpa螺栓孔中心距和法蘭(lan) 外徑，800以上管徑(含)，參照國標0.6Mpa螺栓孔中心距和法蘭(lan) 外徑。
The earliest design duckbill valve, to matched with the national standards, the provisions of the 800 the following caliber duckbill valve flange standard reference GB 1.0MPa bolt hole center distance and diameter of flange, pipe diameter of more than 800 (inclusive), according to GB 0.6MPa bolt hole center distance and diameter of flange.
