Integrated cast iron gate with machine闸

Gates are control devices used to close and open water discharge channels. An essential component of hydraulic structures, they can be used to block water flow, control water levels, regulate flow rates, and discharge silt and floating debris, among other functions.

The gate is mainly composed of three parts:
① The main activity section, used for closing or opening apertures, commonly known as a gate, also referred to as a gate leaf.
② Grouted section
③ Shut-off equipment.
The activity section includes weighing structures such as panel beams, support and walking components, guiding and sealing devices, and lifting lugs. The embedded section includes main tracks, guide tracks, hinge seats, lintels, sill plates, and sealing seats, which are embedded around the orifices and securely connected to the concrete of hydraulic structures with anchor rods. They form supports and sealing surfaces on the door leaves, facilitating the transfer of water pressure and other loads on the door leaf structure to the hydraulic structures, and achieving excellent gate sealing performance. The opening and closing machinery is connected to the lifting lugs of the door leaves to control the position of the activity section, but some gates also operate automatically with hydraulic control.
