FRP flap gate

FRP flap gates, made of fiberglass, are lightweight and corrosion-resistant. They have multiple features, diverse specs, and wide use in water-related projects and various systems for efficient flow control.

Position:

FRP flap gates are efficient, economical, and safe hydraulic valves used in various water supply, drainage, and sewage treatment projects. They are mainly made of fiberglass-reinforced plastic, which has excellent corrosion resistance and can withstand environmental factors such as acidity, alkalinity, saltwater, and climate. The main body consists of four parts: the valve body, valve plate, sealing ring, and chain, with simple operation and the ability to achieve full automation. Additionally, when operated under normal conditions, flap gates can contribute to energy savings.

Performance Characteristics:

1. Lightweight: Fiberglass is a composite material that is much lighter than traditional materials like cast iron flap gates for the same volume, making it easier to install and maintain.

2. Corrosion Resistance and Aging Resistance: Fiberglass has excellent corrosion resistance against environmental factors such as acidity, alkalinity, saltwater, and climate. It also exhibits aging resistance, ensuring long-term use without damage.

3. Good Theft Prevention: Since fiberglass flap gates have no recyclable value, they are an effective anti-theft option.

4. Low Opening and Closing Force: Designed with a larger opening angle, fiberglass flap gates significantly reduce the force required for opening and closing, making operation more convenient.

5. Superior Mechanical Properties: Fiberglass flap gates have excellent mechanical properties, including high strength and good toughness, enabling them to operate stably in various environments.

6. Strong Design Flexibility: Fiberglass flap gates come in flexible and diverse designs, allowing for customization based on specific project requirements to meet certain functional and aesthetic demands.

7. Increased Efficiency of Pumping Devices: Fiberglass flap gates effectively prevent water backflow, significantly improving the efficiency of pumping devices.

8. Bright Appearance, Diverse Colors: Compared to cast iron flap gates, fiberglass flap gates have a brighter appearance and offer a wider range of color choices, making them better suited to blend into various environments and architectural styles.

Parameter Specifications:

Caliber Specifications: The diameter range for circular flap gates is DN200-2600mm, and for square flap gates, it is 300-3000mm.

Applicable Media: Suitable for industrial, domestic sewage, seawater, etc., with acidic and alkaline properties.

Operating Temperature: Generally, the operating temperature does not exceed 60 degrees Celsius. Depending on the requirements, flap gates can be designed to withstand temperatures of up to 100 degrees Celsius.

Operating Pressure: Varies from atmospheric pressure to 0.25MPa.

Sealing Ring Form: Includes lip seal and hollow circular tube seal.

Flap Gate Opening Angle: Greater than 60 degrees.

Barcol Hardness: Between 30-40.

Fiberglass flap gates come in various specifications and can be selected according to specific application needs and environmental conditions.

Application Areas:

Water Supply, Drainage, and Sewage Treatment Projects: Fiberglass flap gates are used for overflow and check purposes in various pipelines and channels, especially at the outlets of unidirectional water flow.

Water Conservancy Systems: Including urban sewage drainage, sewage treatment plant drainage, water conservancy projects, and urban flood control and flood prevention. Fiberglass flap gates prevent external water from flowing back into pipelines and are mainly installed at the end of drainage pipelines.

Drainage Pipe Outlets along Riverbanks: As a one-way valve, fiberglass flap gates automatically open and close, providing good water sealing and backflow prevention properties, making them suitable for drainage pipe outlets along riverbanks.

Municipal Sewage Systems: Fiberglass flap gates are also suitable for municipal sewage systems to prevent external water from backflowing.

Specific Environmental Applications: For example, when flap gates are installed at the outlet of a riverbank drainage pipe, the flap gate automatically closes when the tide level of the river is higher than the outlet and the pressure is greater than the pressure inside the pipe, preventing the tide from entering the drainage pipe.
