Steel flap gates are hydraulic control devices constructed from steel, primarily used in reservoirs, rivers, urban flood control, and irrigation systems. They achieve automatic water level regulation through the balance of hydraulic pressure and self-weight.
Structural Features
The main structure employs a steel gate design, with components such as panels, piers, and legs made of steel, offering strong corrosion resistance and structural durability. Some models use stainless steel materials to adapt to corrosive environments like sewage, ensuring excellent sealing performance that can be maintained by replacing sealing devices.
Function and Principle
Operation relies on the moment balance principle between water pressure and gate gravity for automatic opening and closing. When upstream water levels rise, hydraulic pressure pushes the gate open to release flow; as water levels drop, the gate closes to retain water, maintaining the set water level range. For example, the roller linkage mechanism reduces vibration through dual pivot links and optimizes flow control with a pre-tilt angle design.
Application Scenarios
Suitable for urban water supply and drainage, hydraulic flood prevention, sewage treatment, and other applications, offering advantages such as low investment costs and convenient maintenance.
