A fixed-wheel steel gate is a type of steel gate that opens and closes by sliding fixed wheels along tracks. It is primarily used in hydraulic engineering to regulate water levels, control water flow, and provide flood prevention. Its structure consists of the gate leaf, embedded parts, hoisting equipment, and accessories, featuring excellent sealing, wear resistance, and corrosion resistance.
Structural Features
Gate Leaf Structure: Welded from low-carbon steel plates, it provides sufficient strength and stiffness, equipped with sealing devices to ensure water tightness.
Embedded Parts: Including sills and side rails, embedded in concrete to provide a stable operating track for the gate.
Hoisting Equipment: Typically uses winch-type or screw-type hoists to perform the lifting and lowering operations of the gate.
Sealing Design: Utilizes rubber sealing devices, with gaps controlled within 0.1mm when fully closed and a leakage rate of ≤0.72L/(min·m).
Application Areas
Suitable for river regulation, hydropower station water diversion, urban flood control, and other projects. It can withstand high water head pressure and has no restrictions on external dimensions.
Anti-Corrosion Process
Surface treatment involves sandblasting for rust removal followed by a hot-dip galvanizing process, effectively extending its service life.
