A flap valve comprises a civil engineering foundation, a telescopic driving device is hinged to the top of the civil engineering foundation, a vertical pull rod is fixed to a telescopic part of the telescopic driving device and stretches into the civil engineering foundation from a top channel of the civil engineering foundation, and a supporting seat is fixed to the interior of the civil engineering foundation and rotationally connected with a rotating shaft. The ends of the connecting rod and the transition rod are fixed to the rotating shaft, and the other end of the transition rod is hinged to one end of the transverse pull rod. Compared with the prior art, the gate has the technical effects that the gate is provided with the transverse pull rod, and when the gate is closed, the axis of the transverse pull rod is vertical to the gate, so that the force of the transverse pull rod can completely act on the gate, the gate is sealed more tightly, and water leakage is avoided. 一种翻板阀，包括土建基础，土建基础的顶部铰接伸缩驱动装置，伸缩驱动
