The difference between
Duckbill Valves with built-in clamps and external clamps is mainly reflected in the installation position and structural design.
1. Installation position:
Duckbill Valve with built-in clamps: usually placed inside the drainage pipe. When installing, place it parallel to the inside of the pipe and tighten the clamp nut. This type of duckbill
Valve is generally placed inside the drainage pipe. You can choose products suitable for your working conditions according to the connection needs of the pipe.
Duckbill valve with external clamps: placed outside the drainage pipe, the sealing end face is usually much larger than the pipe diameter. This type of duckbill valve is installed outside the pipe and connected to the pipe through a clamp.
2. Structural design:
Duckbill Check Valve with built-in clamps: a metal cavity is added on the basis of the
Flange-type flexible check valve, with flanges on both ends, which can replace the traditional pipeline check valve. This design makes the
Built-in Duckbill Valve have high reliability and maintenance-free characteristics.
Duckbill valve with external clamps: usually adopts a sleeve design, which is inserted into the matching connecting pipe. The pipe and the inner wall of the sleeve can be coated with hydraulic glue for sealing, and fixed with a metal clamp.
3. Application scenarios:
Internal clamp duckbill valve: suitable for occasions where it needs to be installed inside the pipeline, it can be better integrated into the pipeline system and reduce the impact on the pipeline appearance.
External clamp duckbill valve: suitable for occasions where it needs to be installed outside the pipeline, which is convenient for maintenance and inspection.
Internal clamp duckbill valve and external clamp duckbill valve have obvious differences in installation position, structural design and application scenarios. The type of duckbill valve to be selected should be determined according to specific working conditions and needs.
