Assembled cast iron gates are hydraulic engineering equipment made from cast iron, featuring a split structure for on-site assembly and installation, suitable for small to medium-sized hydraulic projects.
Structural Features
Split Design: The gate body is divided into multiple detachable components, fixed with anchor bolts or embedded parts, facilitating transportation and on-site installation.
Material: The main body is made of HT250 gray cast iron or ductile cast iron, complying with CJ/T3006-92 and DL/T5018-2004 standards.
Sealing System: Utilizes copper alloy facings or rubber sealing strips, achieving bidirectional water stoppage through wedge mechanisms, with leakage controlled between 0.03-0.07 L/m·s.
Applications
Primarily used in hydraulic projects such as reservoirs, rivers, and hydropower stations, driven by hoists to regulate water levels and intercept flow. Their assembled design reduces transportation challenges, making them especially suitable for projects with limited access or constrained construction conditions.
Installation Requirements
Requires overall hoisting into the slot followed by secondary concrete pouring, adjusting sealing surface gaps to within 0.1mm, and regular lubrication and anti-corrosion maintenance.
