Product Description: A stoplog gate is a planar water-retaining structure composed of multiple independent stoplog planks stacked horizontally, primarily used for temporary water retention or equipment maintenance in hydraulic engineering. The following are its key points:Structural FeaturesA stoplog gate consists of multiple stoplog planks, each equipped with protrusions, grooves, and rubber water seals, enabling opening and closing functions via gate slots. Traditional structures rely on the self-weight of the planks and rubber water seals for sealing, resulting in poor integrity and significant leakage (approximately 1.5-5 L/(min·m)). An improved design with pre-tightening devices reduces misalignment through slide positioning and close-contact mechanisms, lowering leakage to 0.3-1.5 L/(min·m). ‌Materials and Applications‌Materials‌: Stainless steel (corrosion-resistant), carbon steel (versatile), and aluminum alloy (lightweight) are the main choices. ‌Applications‌:Temporary water retention: Such as during hydraulic maintenance periods or channel blocking in wastewater treatment plants.Permanent water retention: In 2024, patented technology enabled the permanent application of double-layer stoplog structures in reservoir hubs, eliminating the need for pumping and drainage during construction. ‌ more>

Product Description: A flap gate is a hydraulic facility that achieves automatic water level regulation 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, support legs, and piers, enabling automatic opening and closing to maintain a set water level range. ‌Core PrincipleThe flap gate operates based on the moment balance principle between water pressure and gate weight: when the upstream water level rises, water pressure pushes the gate to rotate around the pivot point, opening to release flow; as the water level drops, the gate automatically closes to retain water, keeping the level within the set range. For instance, the roller-link mechanism utilizes dual-pivot linkages to achieve automatic regulation, avoiding vibration and slamming issues common in traditional gate operations. ‌ more>
