 弧形铸铁闸门 铸铁闸门是一种小型平板闸门，广泛使用于取水输水、市政建设，给水排水、农田灌溉等工程中，通常设置在渠道、涵管的进水口，用作工作闸门调节流量、控制水位，或用作检修闸门关闭孔口挡水。 

Arc cast iron gate iron gate is a small flat gate, widely used in water conveyance, municipal construction, water supply and drainage and irrigation projects, usually set in inlet channel, culvert, adjust the flow and water level control gate used, or used as a water retaining gate closed orifice.  

铸铁闸门有方形、圆形两种。铸铁闸门一般由门叶和门框两部分组成，门体和门框的材料为铸铁，一般整体铸造、整体加工。 

The cast iron gate has two kinds of square and circular. The iron gate is generally composed of two parts of the door leaf and the door frame. The material of the door and the door frame is cast iron, which is generally cast and processed as a whole.  

门体一般采用面板与加强肋的结构，面板可做平面或拱形。门体一般整体铸造和机加工，但尺寸较大的可采用分块组成式。门体上一般采用整体式金属止水，兼作支承滑块，金属止水用同材料制作的沉头螺钉紧固在门体上，螺钉头部与止水工作面一起精加工，一些尺寸较大的也可“P”形橡皮止水。 

The door body generally adopts the structure of the panel and the stiffening rib, and the panel can be made of plane or arch. The door body is generally cast and machined as a whole, but the larger size can be used as a block composition. Generally, the door body is made of holistic metal water stop. It is also used as a supporting slide block. The metal sealing water is fastened to the door body with the countersunk screws made of the same material. The head of the screw is fined together with the water stopping working surface, and some larger sizes can also be made of "P" shape rubber seal.  

门框为铸铁闸门与基础之间的连接构件，相当于平面钢闸门的埋高部分。门框包括下部门框和上部导轨两部分。下部门框一般整体铸造加工，导轨可用螺栓（螺钉）与门框相接，或与下部门框整体铸造，在门体开启到最高位置时，导轨的顶端应高于门体的水平中心线。 

The door frame is a connecting member between the cast iron gate and the foundation, which is equivalent to the buried part of the flat steel gate. The door frame consists of two parts of the lower doorframe and the upper guide. The lower door frame is generally cast in the whole process. The guide rail can be connected with the door frame or the lower door frame as a whole, and the top of the guide rail should be higher than the horizontal central line of the door body when the door body is opened to the highest position.  

特点： 

Features:

铸铁闸门一般设置有可调节的楔紧装置，楔紧副（如楔块与楔块、楔块与偏心销等）分别设在门体和门框上。调节楔紧装置，可使得闸门关闭时门体紧贴门框，达到止水要求。 

The iron gate is usually set with adjustable wedge, and the wedge (such as wedges and wedges, wedges and eccentric pins) are located on the door and door frame, respectively. The adjustment of the wedge can make the door close to the door frame when the gate is closed, so as to meet the requirements of water stop.  

铸铁闸门通常配置手动或电动螺杆式启闭机，用于操作闸门的启闭。 

The iron gate is usually equipped with manual or electric screw hoist, which is used to operate the gate opening and closing.  

铸铁闸门有以下特点： 

Iron gate has the following characteristics:

布置简单，结构紧凑，节省空间；运行维护简单，减少运行费用，但铸铁闸门的造价比钢闸门略高一些。 

Simple arrangement, compact structure, space saving, simple operation and maintenance, reduce operation cost, but the cost of cast iron gate is slightly higher than that of steel gate.  

耐腐蚀性强。门体和门框的材料采用铸铁，止水面镶铜合金或不锈钢等耐腐蚀材料，防腐能力强，特别适用于污水或海水环境中。有特殊要求的地方还可以采用镍铬合金铸铁等耐腐蚀性更强的材料。

Strong corrosion resistance. The material of door body and door frame is made of cast iron, water resisting copper alloy or stainless steel and so on. It has strong anticorrosive ability. It is especially suitable for sewage or seawater environment. In places with special requirements, nickel - chromium alloy cast iron and other materials with more corrosion resistance can also be used.
