Product Description: Steel flap gates are hydraulic control devices constructed from steel, primarily used in reservoirs, rivers, urban flood control, and irrigation systems. They achieve automatic water level regulation through the balance of hydraulic pressure and self-weight. Structural FeaturesThe main structure employs a steel gate design, with components such as panels, piers, and legs made of steel, offering strong corrosion resistance and structural durability. Some models use stainless steel materials to adapt to corrosive environments like sewage, ensuring excellent sealing performance that can be maintained by replacing sealing devices. Function and PrincipleOperation relies on the moment balance principle between water pressure and gate gravity for automatic opening and closing. When upstream water levels rise, hydraulic pressure pushes the gate open to release flow; as water levels drop, the gate closes to retain water, maintaining the set water level range. For example, the roller linkage mechanism reduces vibration through dual pivot links and optimizes flow control with a pre-tilt angle design. Application ScenariosSuitable for urban water supply and drainage, hydraulic flood prevention, sewage treatment, and other applications, offering advantages such as low investment costs and convenient maintenance. more>

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>

Gate valves are relatively easy to open and close. 3. The flow direction of the medium in gate valves is not restricted, without disturbing the flow or reducing pressure. 4. Gate valves have a simple shape, short structural length, good manufacturability, and a wide range of applications. The disadvantages of gate valves are as follows: 1. The sealing surfaces of gate valves are prone to erosion and wear, making maintenance relatively difficult. 2. Gate valves have large external dimensions, require certain space for opening, and have long opening and closing times. more>
