Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy equipment, in particular to a hydraulic power torque arm. Background Art

[0002] The gate is a control facility used to close and open the water discharge (release) channel. It is an important part of hydraulic structures and can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. The gate includes a revolving gate and a vertical gate.
