Bi-directional Water-Stop Cast Iron Gate with Bronze Inlay

The bidirectional water-stop cast iron copper-inlaid gate is a key equipment used in water supply and drainage, flood control, sewage treatment, and other engineering projects. It features bidirectional pressure-bearing and bidirectional water-stop functions, preventing media backflow. Its core structure includes a gate frame, gate plate, sealing strip, guide rail, and adjustment mechanism, made of cast iron to ensure strength and corrosion resistance.
Structural Features
Material: The main body uses gray cast iron or ductile iron, with copper or rubber inlaid on the sealing surface. The outer arc design enhances uniform stress distribution.
Sealing Performance: The sealing gap is adjusted to ≤0.1mm via a wedge device, with forward leakage ≤0.7L/m·min and reverse leakage ≤1.25L/m·min.
Installation: Supports embedded steel plate or bolt fixation, compatible with manual/electric/hydraulic hoists.
Performance Parameters
Pressure-Bearing Capacity: Maximum forward/reverse head of 10 meters, nominal pressure ≤0.1MPa.
Operating Temperature: -20℃ to 120℃, suitable for various media such as sewage and seawater.
Opening/Closing Speed: 0.2-1.5 meters per minute, supports remote control.
Application Scenarios
Primarily used in municipal water supply and drainage, river cutoff, sewage treatment, industrial water treatment, and other scenarios requiring bidirectional water-stop to avoid sewage backflow risks.
