Application scenarios：
The internal reflux rotary gate is mainly used in water supply, drainage, and sewage treatment engineering to regulate flow rates and alter flow directions, among other functions.
Structure&Principle：
The gate adopts a planar reinforced design with built-in installation. It is operated by a hoist that drives the rotation of the transmission shaft. Under the action of the transmission shaft and connecting rod, the gate body rotates 0–90° along the axis, thereby achieving the purpose of intercepting or altering the direction of water flow.
Main Features：
1. The gate can be made of carbon steel or stainless steel.
2. During installation, the gate must be aligned vertically and on the same axis as the ground, with a permissible deviation of less than 1/1000 mm.
3. This gate can be equipped with a manual or dual manual-electric drive mechanism, using a partial rotation design. When operated manually, the required force is less than 150 N.
