拍门的安装使用 

Installation and use of clapping doors

1、拍门安装可与法兰连接，可预埋，也可永插； 

1. The installation of the clapping door can be connected with the flange, which can be buried or inserted permanently.

2、配重拍门使用时，如果正向水力不足，不能开启门页，可根据安装位置需要设置不等重量的配重装置； 

2. When the counterweight clap door is used, if the forward hydraulic force is insufficient and the door page cannot be opened, the counterweight device of different weight can be set according to the installation location.

3、  浮箱 拍门 在使用过程中，可通过向门页密封腔体内注水或放水的方法改变门页的比重，以达到最佳开启效果。 

3. During the use of the floating box door, the proportion of the door pages can be changed by injecting or releasing water into the sealing chamber of the door pages to achieve the best opening effect.  

4、  多台拍门安装时，如因起吊条件限制需分号安装，应注意标注标记，因每台拍门的门座和门页连接属偶配，不能互换。 

4. When installing several flapping doors, if the semicolon installation is required due to the limitation of lifting conditions, attention should be paid to labeling, because the connection between the door seat and the door page of each flapping door is a spouse and cannot be interchanged.  

5、穿墙管安装轴线与水平方向的夹角a应大于或等于零度 

5. The angle a between the installation axis and the horizontal direction of the wall-piercing pipe shall be greater than or equal to zero degrees.

6、拍门安装后，门座与门页间有3mm左右的间隙属正常现象，当门页承受一定的反向压力时，间隙会减少以致消失。

6. After the door is installed, the gap between the door seat and the door page is about 3 mm, which is normal. When the door page bears a certain reverse pressure, the gap will be reduced or disappeared.

 

 

主要技术特点：

Main technical features:

1、无需任何启闭装置，能自动启闭。与悬挂式拍门相比最显著的特点是：将阀体铰轴竖向布置，并设计了一个最佳倾斜角度，利用门重分力作闭门的动力，不管大、中、小通径拍门，均无需任何启闭装置。

1. It can automatically start and close without any lifting and closing devices. Compared with the suspended clapping door, the most remarkable feature is that the hinge shaft of the valve body is vertically arranged, and an optimum inclination angle is designed. The power of closing the door is based on the weight component of the door, and no hoisting device is needed for large, medium and small diameter clapping doors.

2。安全稳定，节能高效。拍门运行时阻力小，开启角度大，闭门时撞击力小，消除了水锤和出水时产生的漩涡；无需手、电、气、液控制，不要人工操作，节省大量人力物力，提高泵站运行可靠性和装置效率，降低运行维护成本，降低泵站能耗。在实际运行中经国家水利部检测测试中心测试，比悬挂式拍门节约电能22.5%。

2. Safety and stability, energy saving and high efficiency. Small resistance, large opening angle, small impact force when closing the door, eliminating the whirlpool generated by water hammer and water outlet; no hand, electricity, gas and liquid control, no manual operation, saving a lot of manpower and material resources, improving the operation reliability and equipment efficiency of the pumping station, reducing operation and maintenance costs, and reducing energy consumption of the pumping station. In actual operation, it saves 22.5% electric energy than the suspended clapping door by testing and testing center of the Ministry of Water Resources.

3。维护方便，使用寿命长。拍门的阀轴为不锈钢材料，轴销座为铜合金石墨润滑轴承，不会锈蚀，密封可靠，门座为碳钢材料；产品结构简单合理，运行轨迹独特，使用寿命可达30年以上，且维护方便。

3. Easy maintenance and long service life. The valve shaft of flapping door is made of stainless steel, and the pin seat is copper alloy graphite lubricated bearing, which is corrosion-free, reliable in sealing and carbon steel material. The structure of the product is simple and reasonable, the running track is unique, the service life can reach more than 30 years, and the maintenance is convenient.
