The gate plays an important role in hydraulic engineering

We usually set restraint cast iron gates on the water delivery pipelines of some water intake and water supply projects to adjust and control the flow according to the needs; the inlet and outlet of the pump station and some tunnels, culverts, inverted siphons, etc. are generally set up with maintenance Gates provide conditions for overhauling hydraulic structures and pumping equipment; flood discharge gates are generally set up on reservoir overflow dams or spillways to control the water level of the reservoir and the flow of floods discharged downstream to maximize the performance of the reservoir. Functional benefits. The gate is the control facility 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, adjust flow, discharge sediment and float, etc.

In water conservancy projects, the gate is one of the important components of hydraulic structures. It can close the orifices of the building according to the needs, or open the orifices in whole or in part to adjust the upstream and downstream water level and flow to obtain The benefits of flood control, irrigation, water supply, power generation, navigation, and rafting can also be used to remove floating objects, sand, ice, etc., or to provide necessary conditions for the maintenance of related buildings and equipment. Cast iron gates are usually set in the main throats of water intake and delivery buildings, and they can be opened and closed flexibly and reliably to exert their functions and benefits and maintain the safety of the building.

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