Agricultural irrigation channel cast iron gates are key equipment in hydraulic engineering used to regulate water levels and control flow, primarily employed in scenarios such as farmland irrigation, flood control, and drought resistance. Below are their core features and technical parameters:
Structural Features
?Main Material?: Made of gray cast iron or ductile iron, offering corrosion resistance and high strength. ?
Sealing Design?: Utilizes copper alloy or rubber sealing strips, achieving bidirectional water stoppage through a wedge block device, with gaps controllable within 0.1 mm. The leakage standard is ≤0.7 L/m·min in the forward direction. ?
Installation Method?: Supports embedded steel plates or bolt fixation, compatible with manual, electric, or hydraulic hoists. ?
Performance Parameters
?Pressure Resistance?: Forward pressure resistance can reach up to 10 meters of water head. ?
Operating Temperature?: Capable of stable operation in environments ranging from -20°C to 120°C. ?
Specification Range?: Common models include the open-stem ZMF series, with gate sizes covering DN200 to DN2500 mm.
