Scope

Scope: Water Conservancy and Irrigation Projects: Small water gates in farmland irrigation systems are used to control the flow and water level of channel water and provide adequate irrigation water for farmland, such as diversion gates on irrigation canals and farm ditches. City Water Supply and Drainage Projects: In urban drainage systems, small water gates can be used for rainwater discharge and wastewater interception, such as the inlet and outlet gates of drainage pump stations, which are used to control the direction and flow of water and prevent river water from flooding back. In urban water supply systems, small water gates can be used to regulate and control the flow of water at water sources, water treatment plants, and distribution pipe networks. Flood Control and Drainage Projects: In small and medium-sized rivers, around lakes, and in low-lying urban areas, small water gates can be used as flood control and drainage gates, such as at the entrances of tributaries of rivers and at key nodes for urban flood prevention. Landscape Water Systems Projects: In urban parks, squares, residential areas, and other landscape water systems, small water gates are used to control the water level and flow of water features and create different water effects, such as inlet and outlet gates of landscape lakes and check gates of artificial streams. Industrial and Other Special Fields: In some industrial enterprises with special water needs, such as paper mills and dyeing factories, small water gates are used to control and regulate water flow. Additionally, in aquaculture ponds and wastewater treatment plants, small water gates are also used for water flow control and management.
