拍门的安装使用 

The installation of the door is used.

1、拍门安装可与法兰连接，可预埋，也可永插； 

1. The flap door installation can be connected to 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 door is used, if the forward hydraulic pressure is insufficient, the door leaf can not be opened, and the counterweight device with unequal weight can be set according to the installation position.

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, the proportion of the door page can be changed by water injection or water release to the door of the door, so as to achieve the best opening effect. It

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 a number of Pat doors are installed, mark marks should be marked, as the door and door pages of each door are connected to each other and cannot be interchanged. It

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 between the installation axis and horizontal direction of the wall tube should be a greater than or equal to zero.

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 and the door has a normal phenomenon of about 3mm. When the door is subjected to a certain reverse pressure, the gap will be reduced so as to disappear.

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. Without any opening and closing device, it can be automatically opened and closed. Compared with the hanging type, the most significant feature is that the valve reaming shaft is arranged vertically, and a best angle of tilt is designed, and the door weight is used as the power to close the door. No open and close devices are needed, regardless of the size of the large, medium and small diameter.

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. Safe and stable, energy saving and high efficiency. It has small resistance, large angle of opening, small impact force when closing the door, eliminating the whirlpool of water hammer and water, without hand, electricity, gas and liquid control, not manual operation, saving a lot of manpower and material power, improving the operation reliability and efficiency of pumping station, reducing the cost of operation and maintenance, and reducing the energy consumption of the pumping station. In actual operation, the test of the testing center of the Ministry of water resources has saved 22.5% of energy compared with the hanging flap door.

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. The maintenance is convenient and the service life is long. The valve shaft of the door is stainless steel, the pin seat is copper alloy graphite lubrication bearing, it will not rust, the seal is reliable, the door seat is carbon steel material; the product structure is simple and reasonable, the running track is unique, the service life can be over 30 years, and the maintenance is convenient.
