[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, agricultural water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and tidal flat reclamation projects. Water conservancy projects that can serve multiple goals such as flood control, water supply, irrigation, and power generation are called comprehensive water conservancy projects. Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems.
