Product Description: The inclined pull-type cast iron gate is a flow control device used in water conservancy projects such as reservoirs, rivers, and hydropower stations. It regulates water levels and intercepts flow by driving the gate plate to lift or lower via a hoist. Its structural features are as follows:Structural CompositionIt mainly consists of a gate frame, gate plate, lifting seat, tight inclined iron, and rod system. The gate frame serves as the supporting component, fixed to the gate pier and secondary concrete of the gate base with anchor bolts, transferring water pressure to the main structure. The gate plate is the water-retaining component directly bearing water pressure, made of cast iron (such as HT250 gray cast iron or ductile iron), complying with industry standards CJ/T3006-92 and DL/T5018-2004.Sealing DesignThe sealing structure uses bronze or copper alloy facings, combined with a wedge block device and water pressure to achieve bidirectional water stoppage. Water seepage can be controlled within 0.03-0.07 L/m·s. The gate plate closely fits the slide track of the gate frame to ensure smooth operation.Installation RequirementsDuring installation, it must be hoisted into the slot as a whole, and the sealing surface gap adjusted to within 0.1 mm through secondary concrete pouring. A matching hoist, such as a manual screw hoist or winch-type hoist, is required to meet different water head pressure needs (e.g., 15-50 m water head).Applicable ScenariosSuitable for water conservancy projects like reservoirs, rivers, and hydropower stations, it offers strong corrosion resistance and can adapt to environments such as sewage and seawater. Its inclined pull-type design optimizes water stoppage effectiveness, reduces sealing surface wear, and simplifies maintenance. more>

Product Description: Hydraulic self-regulating flap gates are facilities that utilize the balance between hydraulic force and self-weight to automatically regulate water levels. They are widely used in water conservancy projects such as reservoirs, rivers, and irrigation systems, featuring simple structure and reliable operation. Core PrincipleEmploying a lever balance and rotation mechanism, the gate's tilt angle is controlled by changes in the moment of water pressure and gate gravity. When the upstream water level rises, the dynamic water pressure increases, causing the gate to open automatically for discharge; when the water level drops, it closes on its own to maintain the set water level range. Structural ComponentsMainly includes panels, legs, piers, rollers, connecting rods, and other components. Taking the roller connecting rod type as an example, the double-pivot structure reduces vibration and optimizes flow control through pre-tilt angle design and trapezoidal practical weirs. Development HistoryChina began research and development in the 1960s, undergoing four generations of technological iterations:First Generation: Horizontal-axis double-pivot hinge typeSecond Generation: Multi-pivot hinge typeThird Generation (1982): Roller connecting rod type, addressing the issue of minor opening slappingFourth Generation (after 1990): Slider-type optimization, improving the flow coefficient Main FunctionsAutomatically regulate water levels to prevent flooding or drought-induced water shortagesOptimize water resource utilization to meet irrigation, power generation, flood control, and other needsEco-friendly, reducing environmental impact Advantages and FeaturesAutomation: No manual operation required, reducing operational costsDurability: Made of steel or composite materials, capable of withstanding immense water pressure and wave impactApplicability: Suitable for small to medium-sized water conservancy projects, with low civil engineering and maintenance costs more>

Product Description: The fixed-wheel gate is a type of flat gate equipped with fixed wheels on its end beams as support and traveling components. It is primarily used in hydropower projects, municipal construction, and agricultural irrigation. The gate consists of a leaf frame, fixed-wheel support devices, rubber waterstop seats, and adjustable wedge-shaped pressing blocks. The entire structure adopts a welded steel plate design, with the end beams featuring a double-web form. The main beams are inserted into the webs of the end beams to form a highly restrained welded connection, with specifications reaching up to 10×10 meters.The fixed wheels of this gate are made of ZG35CrMo material and undergo quenching and tempering treatment, with a tread hardness of 390-420 HBS. The height difference between treads on the same side is controlled to ≤0.5 mm. During manufacturing, CO₂ gas shielded welding and submerged arc automatic welding processes are employed. The fixed-wheel supports are assembled after processing, and an 18-meter planer milling machine is used to finish the waterstop seat surface, ensuring flatness ≤0.5 mm. The surface undergoes sandblasting for rust removal and hot-dip zinc anti-corrosion treatment, with a spraying distance of 100-200 mm and pressure ≥0.4 MPa, providing a service life of up to 30 years.The leakage rate of the gate does not exceed 0.03 liters/second·meter. When subjected to high water heads, groove pulleys can be added to reduce frictional resistance. During installation, the flatness of the gate slot embedded parts must be controlled to ≤2 mm, and the main wheel tracks are fixed with secondary concrete. The sealing performance can be adjusted and restored using wedge-shaped pressing blocks. more>

Product Description: The arc gate hoist is a type of hoisting equipment used to operate radial gates, primarily employed in hydraulic and hydroelectric engineering for gate control. It features a compact structure, high hoisting capacity, and flexible travel. Structural CompositionIt mainly consists of components such as the motor, reducer, drum, steel wire rope, pulley block, and frame. Through the reducer and pulley block, torque amplification is achieved, making it suitable for operating large-sized gates. Functional FeaturesHigh Hoisting Capacity: By combining the reducer and pulley block, a significant gate-opening force can be obtained, making it suitable for large openings or high-head gates. Flexible Travel: The direction of force on the steel wire rope can be adjusted, and with the use of deflection pulleys, it can adapt to gate opening requirements at different angles. Synchronized Control: The double-lifting point design ensures synchronous operation on both sides, guaranteeing smooth opening and closing of the radial gate. Safety Configurations: Equipped with a speed-limiting device (speed ≤ 5 m/min when approaching the sill) and a braking system to prevent gate falling or collision. Application ScenariosPrimarily used for controlling radial gates in hydraulic and hydroelectric engineering, such as emergency gates or inspection gates in reservoirs and hydropower stations. It also features rapid closing functionality to respond to emergencies. Maintenance ConsiderationsRegular inspections of the steel wire rope arrangement, braking system, and lubrication are necessary to avoid failures caused by rust or jamming. more>
