We usually set up control cast iron gate in some water supply pipeline, which is used to adjust and control the flow according to the need. Access gates are generally installed at the inlet and outlet of the pumping station and some tunnels, culverts and inverted siphon to provide conditions for the maintenance of hydraulic structures and pump equipment; The spillway or spillway of a reservoir is usually equipped with a sluice gate to control the water level of the reservoir and the flood flow to the downstream, so as to give full play to the functions and benefits of the reservoir. A gate is a control device used to close and open a discharge (discharge) passage. An important part of a hydraulic structure that can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating matter.
In water conservancy engineering, the gate is one of the important part of hydraulic structures, it can be closed the structure of the orifice according to the need, also can open the orifice, whole or partial is used to adjust the upstream and downstream water level and flow, for flood control, irrigation, water supply, power generation, navigation, wooden raft of benefits, can also be used to eliminate floater, mud, ice, etc., or for related building and equipment maintenance provides necessary conditions. Cast iron gate is usually installed in the intake and outlet of water intake and conveyance building, which can be opened and closed flexibly and reliably to play their functions and benefits and maintain the safety of the building.
Cast iron gate is usually composed of movable part (also known as the gate blade), embedded solid part and lifting and closing machinery. Leaf includes: bearing structure, walking support, arm, hinge, stop water device, lifting lug, etc. Embedded solid part includes: track, hinge seat, water stop seat, Angle protection, etc.
