Energy-saving flap valve

Energy-saving flap gate is a new type of hydraulic equipment that reduces energy consumption and enhances pump station operational efficiency through optimized design. Below are its core features:
Design Principle
It adopts a design with the vertical gate axially inclined at a certain angle, utilizing the component force of the gate's self-weight to achieve automatic opening and closing, with an opening angle of over 80°. This structure reduces the opening force to only 1/5 of the gate's weight in non-submerged conditions, significantly minimizing water flow resistance.
Technical Advantages
Energy-saving effect: Saves 22.5% more electricity compared to traditional flap gates, reducing energy consumption by minimizing water hammer effects and outlet vortices.
Reliability: The main body is made of carbon steel, with sealing surfaces combining cast steel and rubber, offering strong corrosion resistance and a service life of up to 30 years.
Easy maintenance: Stainless steel valve shafts and copper alloy pin seat designs reduce rust risks, featuring a simple structure for easy upkeep.
Application Scenarios
Primarily used in hydraulic engineering projects such as flood control and drainage, agricultural irrigation, urban water supply and drainage, and inter-basin water transfer. It is particularly suitable for renovation projects in medium and low-lift pump stations.
This equipment has been tested and certified by the Ministry of Water Resources, featuring reliable self-closing functionality and high operational efficiency, and can be adapted for circular or rectangular gate designs.
