Meanwhile, the flap valve can be used to adjust weight, spring tension and the bottom outlet valve flap valve opening size to determine the pressure and open and close time.
同时，可以利用调整阀瓣的自重、弹簧的弹力以及阀瓣的底孔大小来确定阀门的开启压力和启闭时间。
When the pressure difference changes with time, a phase shift will occur between the transient pressure difference and displace of valve flap, which could cause leakage and even reverse flow.
当阀片两侧的压差随时间变化时，阀片的启闭与压差的变化之间存在一定的相位差，有可能引起泄漏甚至反向流动。
This valve is normally automatic work, in a direction of flow of fluid under pressure, open the flap valve;
通常这种阀门是自动工作的，在一个方向流动的流体压力作用下，阀瓣打开；
When the relative gap height (the ratio of flap height to gap width) is in the range of 0 8-2 0, the mean pressure will reduced 30% if the flap height is smaller than the thickness of boundary layer.
底部相对间隙在08～ 2 0之间时，扰流片高度小于边界层厚度时的壁面平均压力比扰流片高度大于边界层厚度时小30 %左右。
Conclusion Trabeculectomy with modified sclera flap may decrease the occurrence of postoperative shallow anterior chamber and control intraocular pressure effectively.
