Product Description: The hydraulic flip gate is a facility that automatically regulates water levels through the balance of hydraulic force and self-weight, primarily used in reservoirs, rivers, and other locations to block or discharge water flow. Its core principle involves lever balance and rotation mechanisms, with structural components including panels, legs, and piers. ‌Core FunctionsThe flip gate automatically opens or closes through hydraulic action: it discharges flow when upstream water levels rise and closes to retain water when levels drop, maintaining a set water level range. For example, the roller-link gate reduces vibration through a dual-pivot structure and employs a trapezoidal practical weir to enhance the flow coefficient. ‌Technological DevelopmentChina began developing this technology in the 1960s, with optimizations across four generations:First Generation‌: Horizontal-axis dual-pivot hinge type‌Second Generation‌: Multi-pivot hinge type‌Third Generation‌ (1982): Roller-link type (vibration reduction)‌Fourth Generation‌ (post-1990): Slider type (performance optimization) ‌Application ScenariosSuitable for small to medium-sized hydraulic engineering projects, including flood control, irrigation, and landscaping, characterized by simple structure and low cost.
