A hydraulic steel gate is a hydraulic engineering device driven by a hydraulic system, primarily used for water retention, flood discharge, and water level regulation. It features a stable structure and flexible operation. Below is a summary of its core information:
1. Product Types and Structure
?Hydraulic Steel Dam Gate?
Constructed from low-carbon alloy steel or reinforced concrete with steel plates, when discharging floods, the dam surface lies flat and rises only 20 cm above the base platform, achieving a near dam-free flood discharge effect.
The hydraulic system is equipped with imported sealing rings, supports automatic lowering without external power, and is suitable for landscape projects (such as waterfalls and water curtain corridors).
?Hydraulic Flat Steel Gate?
Composed of hydraulic cylinders, pump stations, and gate leaves, with a water retention height of ≤5 meters and a single leaf width of ≤12 meters. It is suitable for river management, hydropower stations, and other applications.
The dual-speed hydraulic system enables rapid closure (within 5 seconds) and is equipped with electromagnetic ball valves and hydraulic check valves for remote control.
?Hydraulic Flap Gate?
Driven by oil cylinders to operate the flap structure, it supports manual/hydraulic operation, offers strong resistance to flood impact, and has a service life of over 50 years.
2. Key Performance Parameters
?Material?: Carbon steel (zinc-sprayed for corrosion resistance) or stainless steel (304/316L), with a 30% improvement in corrosion resistance.
?Sealing?: Imported sealing rings combined with rubber-plastic waterstop devices, ensuring no corrosion during long-term underwater operation.
?Hoisting Capacity?: Electrically driven large gates can achieve a hoisting force of up to 1200 kN.
