The stepped low-pressurized water diversion system is a new type of gravity water supply system, which is simple in structure and water conservation weir is the pivotal structure.
The utility model has simple structure, and adopts gravity flow type cooling medium, thus having small power consumption, high heat transfer efficiency and cycle use.
