Non-negative-pressure tank-type pressure-superposed partitioned water supply equipment

The utility model discloses non-negative pressure tank type pressure-superposed partition water supply equipment, which belongs to the technical field of water supply equipment and comprises a base, a fixing frame, a filter frame, a water inlet A, a water outlet, a valve, a non-negative pressure tank, a vacuum suppressor, a water inlet, a check valve A, a water pump A, a low-pressure water pump B, a water inlet B, a high-pressure water pump C and a water inlet C. The top of the outer wall of the base is fixedly provided with the fixing frame. A non-negative-pressure tank is fixedly installed in the middle of the top of the outer wall of the base. Impurities and the like doped in water resources are blocked by the filter screen rack A, and the filter screen rack A is prevented from being blocked by continuously swinging left and right, and meanwhile, the filtered water resources fall to the bottom of the filter rack; the valve and the water pump A are opened, a large amount of water resources are guided into t
