Introduction of duckbill valve;
First, the main use of duckbill valve
Duckbill valve is widely used in coastal, beach, wharf, reservoir, municipal flood discharge and sewage discharge. It can be described as an environmentally-friendly green valve, which replaces the check valve of flapper door and thoroughly solves the problem that flapper door is easily blocked by silt, mud, rocks, vegetation and marine life. Duckbill valve products are mainly used in waterproof system, drainage system, water pump outlet, lifting pump station and submerged aeration system.
Second, the working principle of duckbill valve
Duckbill valve is made of elastic chloroprene rubber and artificial fiber by special processing, and its shape is similar to duckbill, so it is called duckbill valve, which is an all-rubber structure. Under the condition of no internal pressure, the duckbill outlet closes under the elastic action of itself; With the gradual increase of internal pressure, the duckbill outlet gradually increases, keeping the liquid discharged at high flow rate, preventing backflow and backflow. Small-diameter duckbill valves need to focus on how to reduce resistance and head loss, while large-diameter duckbill valves need to consider how to prevent reverse backwater.
Silicone Umbrella Valves, known as Mushroom Valves or Umbrella Check Valves. Rubber Umbrella Valves have round diaphragm seals & seat for air or water pressure relief and backflow controls. The stem and hooks of umbrella valve is for fixing. Umbrella valves are generally made from medical grade or food garde silicone or LSR materials. Other rubber materials like EPDM, NBR etc. are available in our company.
Duckbill Vallve, as a elastomeric fluid-flow control components, seals or nozzles, is one type of rubber one way valves. The duckbill design aim to automatically prevent air or fluid backflow and allow forward flow.
