Chapter 1: Basics and Evolution of Hydraulic Electric Gate Valves
1.1 Basic Functions of Hydraulic Electric Gate Valves
In hydropower systems, gate valves play a critical role in controlling the flow rate and water pressure. They precisely regulate the direction, flow, and water level to ensure the stable and efficient operation of the hydropower generator units. Hydropower facilities require varying amounts of water flow and pressure at different operational stages, and it is the gate valve's responsibility to ensure these requirements are met accurately. The basic functions of gate valves include:

Regulating Water Flow: The gate valve adjusts the opening degree to control the flow of water into the hydropower generator unit, ensuring that the generator operates at optimal performance.
Controlling Water Pressure: The gate valve can regulate the flow rate to control water pressure, preventing equipment damage caused by excessive or insufficient water pressure.
Protecting Equipment Safety: In emergencies, such as equipment failures or abnormal water flows, the gate valve automatically shuts off the water flow, preventing damage to the equipment.
1.2 Technological Evolution of Hydraulic Electric Gate Valves
Hydraulic electric gate valves have evolved from manual control systems to electric control and now to smart, automated control systems. Early hydraulic electric gate valves were primarily manually operated, which was cumbersome and inefficient. With the advancement of electric control technology, gate valves gradually transitioned to being driven by electric actuators, offering faster and more precise adjustments. However, these electric valves still faced limitations such as inadequate real-time data acquisition and lack of remote monitoring capabilities.

In recent years, with the rapid development of IoT, AI, and big data technologies, smart hydraulic electric gate valves have emerged. These smart valves can not only automatically regulate water flow, but also provide real-time monitoring of water pressure, flow rate, and other critical data. They use integrated control systems to make intelligent adjustments and can issue alerts in case of faults, ensuring the safety and stability of equipment.
