Phi-shaped water gate

The Phi-shaped water gate is suitable for various water channels. Rotating the middle shaft to rotate the gate plate by 90 deg opens the gate and the upper gate frame is made to close to channel side while the gate plate is made to close to the channel side. The gate plate closing to the channel side is parallel to the water flow. By utilizing natural force in several places, the gate controls water flow simply with less force. 一种中字闸门，适用于多种水渠。将中轴转动带动门板旋转90度角使闸门开启，将门板靠到渠边的同时可将上门框一同靠到渠边，在门板从渠中央靠到渠边的过程中，门板始终与水流平行。该闸门多处利用自然力，达到疏导和控制水流的目的，使开关闸门十分简单和省力。
