Why Is Steel Penstock Gate a Key Link in Water Conservancy Projects?

Steel Penstock Gate is a common hydraulic gate, mainly made of steel, and generally includes gate leaf structure, embedded components, hoist mechanical transmission parts and other parts. The gate leaf structure is its main body, which plays a key role such as water blocking. The embedded components are used to fix the gate at the corresponding gate hole, and the hoist controls the opening and closing operation of the gate.

The advantages of Steel Penstock Gate come from its material and structural design. Steel has high strength and hardness, can withstand large water pressure, water flow impact and other external forces, and is suitable for various complex water conservancy project environments. After anti-corrosion treatment, steel has good corrosion resistance, can maintain good performance in long-term underwater environments, and has a long service life. Steel is easy to process and manufacture, and can be made into gates of various shapes and sizes according to different engineering requirements to meet diverse design requirements.

Through reasonable sealing design, such as installing sealing materials such as rubber waterstops, water leakage can be effectively prevented to ensure the normal operation of water conservancy projects. It can be used with various opening and closing devices to realize flexible opening and closing of the gate, which is easy to operate and can meet the use requirements under different working conditions.

Steel Penstock Gate is divided into working gates (used for regular adjustment of water level, flow control, etc., such as steel gates of regulating gates on irrigation channels), maintenance gates (used to block water when repairing hydraulic structures or other gates, such as the maintenance steel gates installed at the water inlet of hydropower station units during maintenance), and emergency gates (when emergencies occur, such as water pipeline ruptures, etc., they are quickly closed to cut off the water flow, such as the emergency steel gates equipped at some important water tunnels).

According to the structural form of the gate: Common ones include flat steel gates (relatively flat in appearance, relatively simple in structure, and widely used, such as many small river sluices commonly use flat steel gates), curved steel gates (arc-shaped, more reasonable in force when opening and closing, often used in large-span gate holes, such as some large ship locks that use curved steel gates), etc.

Steel Penstock Gate is widely used in various water conservancy projects, such as reservoirs, dams, rivers, channels, etc. In reservoirs, steel gates are used to control the storage and release of reservoirs and adjust water levels; on dams, they are used to intercept water flow and control flow; in rivers and channels, they are used to adjust water flow and prevent floods. In addition, it can also be used in some industrial fields, such as sewage treatment plants, chemical plants, etc., to control the flow of sewage or chemical media.

Steel Penstock Gate anti-corrosion requires sufficient effort. Cleaning the surface, removing rust and decontamination are basic, and anti-rust primer and high-performance topcoat must be applied, and regular inspections and repairs must be carried out to ensure that the gate is long-lasting and durable.
