Description

Technical Field

[0001] The utility model belongs to the technical field of duckbill valve processing, in particular to a duckbill valve bent mouth shaping device. Background Art

[0002] Duckbill valves are made of specially processed elastic neoprene and synthetic fibers, shaped like a duckbill, hence the name. When pressure is low, the duckbill's outlet closes due to its own elasticity. As internal pressure increases, the outlet gradually expands, allowing liquid to be discharged at a high flow rate.

[0003] In order to prevent liquid reflux, some duckbill valves are bent and shaped at the duckbill outlet to form a curved mouth structure. When bending and shaping the duckbill valve, the shape and density of the curved mouth need to be considered. This results in a complex structure of the duckbill valve bending mouth shaping device in the existing technology, and the process of placing the curved mouth valve in the shaping device is cumbersome and inconvenient to operate.
