The important role of steel gate in hydraulic engineering

We generally set up control cast iron steel gates on the water delivery pipelines of some water intake and water supply projects, which are used to control the flow according to the needs; in the pump station inlet and some tunnels, culverts, inverted siphons, etc., the inlet and outlet are generally set Overhaul steel gates to provide conditions for overhauling hydraulic buildings and pumping equipment; generally, there are flood discharge working steel gates on reservoir overflow dams or spillways, which are used to control the water level of the reservoir and the flow of flood discharged downstream, to the greatest extent Give full play to the functional benefits of reservoirs. The steel gate is the control device used to close and open the water discharge (discharge) channel. An important part of hydraulic structures can be used to intercept water flow, control water level, dispatch flow, discharge sediment and float, etc.

In water conservancy projects, steel gates are one of the important components of hydraulic buildings. They can close the orifices of the building according to needs, and can also open all or part of the orifices for scheduling the upper and lower water levels and flows, thereby Obtaining benefits such as flood control, irrigation, water supply, power generation, navigation, and rafting, can also be used to remove floating objects, sediment, ice, etc., and may provide necessary conditions for the maintenance of related buildings and equipment. Cast iron steel gates are generally installed in the main throats of water intake and water delivery buildings, and they can be flexibly and reliably opened and closed through steel gates to exert their functions and benefits and maintain the safety of the building.

Cast iron steel gate generally consists of three parts: movable part (also called door leaf), buried part and opening and closing machinery. The door leaf includes: load-bearing structure, walking support, support arm, support hinge, water-stop equipment, lifting lugs, etc. Buried parts include: track, hinge seat, water stop, corner protector, etc.
