 我们通常在一些取水供水工程的输水管道上一般设置节制铸铁闸门,用于根据需要调节控制流量;在泵站进水口和一些隧道、涵管、倒虹管等的进、出水口一般设置有检修闸门,为检修水工建筑物和泵组设备提供条件;在水库溢流坝或溢洪道上一般设置有泄洪工作闸门,用于控制水库的水位和泄往下游的洪水流量,最大限度地发挥水库的功能效益。闸门就是用于关闭和开放泄(放)水通道的控制设施。水工建筑物的重要组成部分,可用以拦截水流,控制水位、调节流量、排放泥沙和飘浮物等。 

 

在水利工程中,闸门是水工建筑物的重要组成部分之一,它可以根据需要来封闭建筑物的孔口,也可全部或局部开启孔口,用于调节上下游水位和流量,从而获得防洪、灌溉、供水、发电、通航、过木过筏等效益,还可用于排除漂浮物、泥沙、冰块等,或者为相关建筑物和设备的检修提供了必要条件。铸铁闸门通常设置在取水输水建筑物的进、出水口等咽喉要道,通过闸门灵活可靠地启闭来发挥它们的功能与效益及维护建筑物的安全。 

 

铸铁闸门通常我们是由活动部分(也称门叶)、埋固部分和启闭机械3部分组成。门叶包括:承重结构、行走支承、支臂、支铰、止水装置、吊耳等。埋固部分包括:轨道、铰座、止水座、护角等

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.
