River Gate Valve

I. Rich Product Types

Plane Gates

Composed of door leaves, door frames, opening and closing equipment, etc., the door leaves have a plane structure, and realize the functions of water retaining and water discharge through close cooperation with the door frames. According to the material, they can be divided into steel plane gates, cast iron plane gates, reinforced concrete plane gates, etc.

They feature a simple structure, convenient manufacturing and installation, and low cost. They can withstand large water pressure and have good water-stopping performance. Suitable for channels, culverts, small reservoirs and other small and medium-sized water conservancy projects, they can be used to control water levels and regulate water flow.

The operation mode is flexible, and various opening and closing methods such as manual, electric, and hydraulic can be adopted to meet the needs of different working conditions.

Arc Gates

The door leaves are arc-shaped, and the water pressure they bear is transmitted to the hinges through the arc panels, with good stress conditions and a compact structure. The commonly used material is steel, which has high strength and rigidity.

They have small opening and closing force, stable operation, good water-stopping effect, and can adapt to large spans and water heads. Widely used in spillways, ship locks, hydropower stations and other large and medium-sized water conservancy projects, they play an important role in releasing floods, regulating water levels, and ensuring navigation.

They are easy to maintain, have a long service life, and can work stably under complex hydrological conditions.

Miter Gates

Composed of two door leaves, they form a "human" shape when closed, and rely on water pressure to press the door leaves tightly on the gate seat to form a sealed water stop. They mainly consist of door leaves, hinge seats, water stop devices, hoists, etc.

They have the advantages of large span, labor-saving opening and closing, and reliable water stopping. They can bear bidirectional water pressure and are suitable for projects that need bidirectional water retaining such as ship locks and check gates.

During operation, the door leaves can be folded without occupying the navigation clear space, having little impact on navigation, so they are a common type of gate in large ship locks.

Flap Gates

They use water power to automatically control the opening and closing of the gate without additional opening and closing equipment. When the upstream water level exceeds the set value, the gate automatically flips open to discharge water under the action of water pressure; after the water level drops, the gate closes to retain water under its own weight.

With a simple structure, low cost, and convenient management, they are suitable for small reservoirs, ponds, irrigation channels and other projects, and can realize the function of automatically regulating water levels.

They can be designed into different forms such as single-hinged flap gates and double-hinged flap gates according to needs to meet different flood discharge and water retaining requirements.

II. Excellent Product Performance

High Strength and Corrosion Resistance:

Gates are made of high-quality steel, cast iron and other raw materials, and undergo strict processing technology and anti-corrosion treatment, so they have high strength and good corrosion resistance. They can maintain structural stability under long-term immersion in water, scouring by water flow and abrasion by sediment, thus extending their service life.

Reliable Water-stopping Performance:

Through the reasonable design of water stop devices, such as rubber water stop strips and metal water stop sheets, the water-stopping effect when the gate is closed is ensured. It can effectively prevent water leakage, reduce water waste, and ensure the normal operation of the project.

Flexible Opening and Closing Performance:

Equipped with advanced opening and closing equipment, such as winch hoists, hydraulic hoists, screw hoists, etc., the gate can be opened and closed flexibly, stably and accurately. Remote control and automatic operation can be realized according to engineering needs, improving the efficiency of project management.

Good Adaptability:

It can adapt to different hydrological, geological conditions and engineering requirements. Whether it is a water conservancy project with high water head and large flow, or a small irrigation channel, suitable gate products can be found. At the same time, customized design and manufacturing can be carried out according to the actual situation of the project.

III. Wide Application Scenarios

Water Conservancy Projects:

In water conservancy facilities such as reservoirs, dams, hydropower stations, and irrigation channels, gates are used to control water levels, regulate water flow, and discharge floods, ensuring the safe operation of water conservancy projects and the rational use of water resources. For example, the spillway gates of reservoirs can discharge floods in time during the flood season to prevent the dam from overtopping; the gates of irrigation channels can regulate the amount of water to meet the needs of farmland irrigation.

Municipal Engineering:

In municipal projects such as urban water supply, drainage, and sewage treatment, gates are used to control the transportation and regulation of water flow. For example, the gates of sewage treatment plants can control the flow direction and flow of sewage to ensure the smooth progress of the sewage treatment process; the gates of urban drainage systems can discharge rainwater in time during heavy rains to prevent urban waterlogging.

Navigation Engineering:

In navigation facilities such as ship locks and waterways, gates are used to regulate water levels so that ships can pass through the lock chamber smoothly. Miter gates and arc gates are widely used in ship locks to ensure the safe navigation of ships.

Industrial Engineering:

In industrial production such as metallurgy, chemical industry, and electric power, gates are used to control the flow and pressure of industrial water, and discharge industrial wastewater. For example, in the cooling water system of thermal power plants, gates can regulate the flow of cooling water to ensure the normal operation of generator sets.
