拍门由阀座(阀体)、阀板、密封圈、铰链四部分构成。仅用于单向水流的圆形和方形出水口，结构严密，工作可靠，无需人力操作启闭力来自水源压力，当拍门内的水压大于拍门外侧压力则开启；反之则关闭。 适用介质：水，河水，江水，海水，生活，工业污水 适用范围 ：适用于水利系统、市政污水、城市防洪排涝、污水处理厂、自来水厂等。
The door is composed of four parts: the valve seat (valve body), the valve plate, the seal ring and the hinge. Only for round and square outlet of one-way flow, the structure is rigorous and reliable. No manpower operation is needed. The opening and closing force comes from the water pressure. When the water pressure in the flap door is larger than that at the outside side of the flap, it opens. Otherwise, it closes. Applicable medium: water, river water, river water, seawater, life and industrial sewage. It is suitable for water system, municipal sewage, urban flood control and drainage, sewage treatment plant, water works, etc.

启闭机安装注意事项：
Attention to the installation of open and close machine:
一、QL螺杆式启闭机：
One, QL screw type hoist:
1、安装时底座地基应牢固平整，留有底脚螺丝的位置，启闭机到位后，找平浇灌成型。
1, the installation base foundation should be firm and smooth, left foot screw position, hoist in place after leveling casting and moulding.
2、启闭机的丝杆必须平行于闸门研磨轨道表面，同时垂直于吊耳轴，双吊点式两个机座必须在同一平面上，两个丝杆平行，同时垂直于吊耳轴，手摇或带电启闭机，先手摇上下启动几次，达到规范后方可带电使用；带电操作时，设有下降深度控制器，但操作人员不得擅自离开场地，以防因电路等故障，造成碰撞事故的发生。
2, open and close machine screw must be parallel to the gate rail surface grinding, and perpendicular to the lug shaft, double hanging point type two base must be in the same plane, two screw rods are parallel and perpendicular to the lug shaft, hand or charged hoist, the upper hand shake to start a few times to meet the standard, before it can be charged to use; charged operation, a drop depth controller, but the operator is not allowed to leave the site, so as to prevent circuit fault caused by collision accidents.
二、QPQ/QPK卷扬式启闭机：
Two, QPQ/QPK hoist type hoist:
1、安装时底座地基应牢固平整，留有底脚螺丝的位置，启闭机到位后，找平浇灌成型。
1, the installation base foundation should be firm and smooth, left foot screw position, hoist in place after leveling casting and moulding.
2、先将钢丝绳绕在平衡轮上，绳长两边均分，通过动滑轮组把钢丝绳绕上去，同时把两端固定在卷筒端部。
2. First, the wire rope is wound on the balance wheel. The two sides of the rope are equally divided, and the wire rope is wound around by the moving pulley group. At the same time, the ends are fixed at the end of the drum.
闸门安装注意事项
Precautions for gate installation
1、在闸门安装前，首先检查各连接部位的螺栓是否因运输装卸中造成的松动，如有松动应加以紧固。
1. Before the installation of the gate, first check the loosening of the bolts in the connecting parts due to the loading and unloading. If the bolt is loose, it should be fastened.
2、检查主立框与横框连结上的止水面是否有错位，如有错位则松动连接螺栓将止水面调整在同一平面内。
2, check whether the surface of the water surface of the main frame and the cross frame is misplaced. If there is a dislocation, the loosening of the connecting bolt will adjust the water to the same plane.
3、闸门安装时应采用整体就位安装，禁止闸框、闸板分体安装，防止闸框变形。
3, when the gate is installed, it should be installed as a whole, and the installation of the gate frame and gate should be prohibited, and the deformation of the gate frame should be prevented.
4、二期浇筑前将闸门整体吊装就位后找好前后、左右的正确位置，然后调整螺栓与工程配钢筋焊牢固。
Before the 4, two phases of the construction of the gate before the overall hoisting to find the right position before and after, and then adjust the bolt and the engineering steel bar welding firmly.
5、闸门出厂前，为了使闸板、闸框贴合的更紧，安装后减少间隙，2米以上的闸门在上下横框上安装了压板卡铁，立框的斜铁上增加了顶丝。注意在间隙调整后将卡铁和斜铁上的顶丝拆除，以使闸门启闭。
5, before the gate goes out, in order to make the gate and brake box fit more tightly, the clearance is reduced after installation. The gate above 2 meters is installed on the upper and lower horizontal frame, and the top wire is added on the inclined iron of the frame. Pay attention to dismantling the top wire on the iron and oblique iron after the clearance adjustment to make the gate open and close.
6、在浇筑混凝土时，流进闸板、闸框、斜铁、挡板间隙中的灰浆应清除，防止灰浆凝固影响启闭
6. In the pouring of concrete, the grout flowing into the sluice, the sluice frame, the slanted iron and the gap between the baffles should be removed to prevent the solidification of the mortar from affecting the opening and closing.
