弧形闸门一般由于没有门槽,从而减少了造成气蚀破坏的危险性,同时启闭力小、操作方便,所以广泛地运用于高压泄水道上做为调节流量的工作闸门。然而,要保证孔口全关时止水严密和在任意开度下泄流不致产生对闸门有害的振动,这在一定程度上取决于沿上游曲线形边界上的止水是否有效与可靠;同时,当闸门启闭时还希望摆脱过大的水封摩阻力,以及伴随而来的对水封本身的严重磨损。所有这些使得大容 Arc gate is generally no gate slot, thereby reducing the risk of cavitation damage, while the opening and closing force is small, easy to operate, it is widely used in high-pressure drain as a work flow regulating gate. However, to ensure that the orifice is fully closed, the tight water stop and the discharge at any opening will not result in detrimental vibrations of the gate, depending to some extent on the effectiveness and reliability of stoppage of water along the curved curve at the upstream end. At the same time, When the gate opening and closing also hope to get rid of excessive water seal friction, and the ensuing serious water seal itself wear. All of this makes great content
