Duckbill Valve
Describe
Square duckbill valve
The square duckbill valve is effective in preventing seawater and sediment intrusion. There is a certain density difference between seawater and discharged sewage. When the discharge of sewage is small, the conventional discharge diffuser will reduce the jet velocity of the nozzle. This density difference will cause seawater to invade the diffuser and bring the sediment in the seabed into the diffusion. Device. The outlet of the square duckbill valve changes with the change of the flow rate, the discharge is closed at zero, and the high jet velocity can be maintained in the case of low emissions, thus preventing the invasion of seawater and environmental sediment.

Square rubber duckbill valve products are mainly used in waterproof systems, exhaust systems, pump outlets, lift pump stations and submerged aeration systems. The main features of the product: the rubber square and the valve body are integrated into one, and the installation is extremely convenient. The valve body is designed with full rubber, which does not cause siltation and jamming, which reduces maintenance costs and allows solid particles to pass smoothly.
