铸铁闸门的门体和门框上分别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)，可使得闸门关闭时门板紧贴门框，达到止水要求。方形铸铁铸铁通常配置手动或电动螺杆式启闭机，用于操作闸门的门体启闭。铸铁闸门由门叶和门框两部分组成，门体和门框的材为铸铁，一般整体铸造、整体加工。

The gate body and frame of the cast iron gate are respectively provided with adjustable wedging devices, and the wedging pairs (such as wedges and wedges, wedges and eccentric pins, etc.) can make the gate plate close to the gate frame when the gate is closed, so as to meet the water stop requirements. Square cast iron is usually equipped with manual or electric screw hoist, which is used to operate the gate body. Cast iron gate is composed of gate leaf and gate frame. The gate body and gate frame are made of cast iron and 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，而一些尺寸较大的闸门也可采用“P”形橡皮止水。

The door body generally adopts the structure of panel and reinforcing rib, and the panel can be plane or arch.
