Duckbill valve application scenarios
1.Sewage treatment and drainage systems: Flanged rubber duckbill valves can effectively prevent sewage backflow and protect treatment facilities from contamination at inlets and outlets, pipe intersections and outlets of sewage treatment plants. Its excellent sealing performance ensures no leakage in the closed state, thus maintaining the normal operation of the wastewater treatment system.
2. Water conservancy engineering: In reservoirs, canals, embankments and other places, flanged rubber duckbill valves can be used to control the direction of water flow and prevent water flow from backfilling or leakage. Its corrosion resistance and wear resistance make it able to operate stably for a long time in harsh water conservancy environment, providing a strong guarantee for the safe operation of water conservancy projects.
3. Marine engineering: In marine engineering, such as coastal protection, port terminals, submarine pipelines and other places, flanged rubber duckbill valves can be used to prevent seawater backflow or pollutants from entering inland waters. Its special duckbill shape design allows the valve to fit snugly to the inner wall of the pipe when closed, forming an effective sealing barrier and protecting the ecological environment of inland waters.
4. Environmental protection engineering: In landfills, leachate treatment systems and other places, flanged rubber duckbill valves can be used to control the discharge of leachate or wastewater. Its good sealing performance and corrosion resistance make it able to operate stably for a long time in these harsh environments, preventing contaminant leakage and polluting the environment.
5. Industrial field: In the chemical, petroleum, pharmaceutical and other industrial fields, flanged rubber duckbill valves can be used to control the flow of various corrosive media. Its all-rubber construction allows the valve to withstand a wide range of chemicals, ensuring the safe and stable operation of the piping system.
