AUTOMATIC WATER-LEVEL POTENTIAL-ENERGY WATER LIFTING DEVICE

摘要

An automatic water-level potential-energy water lifting device is provided. A water discharging opening (12) of the main body (10) is provided with a water discharging valve (20). A water supply opening (13) of the main body is provided with a gravity-actuated ball-headed shaft (30). The water supply opening is connected with a pressure tank (40). When the water flows from the body to the pressure tank, the weight of the gravity-actuated ball-headed shaft and a gravity-actuated pin (24) of the water discharging valve enables the water to be subjected to the pressure of the water in the main body and the air in the pressure tank. Instantaneous high pressure pushes the water to a higher position, thus electric energy is not needed. The simple structure of the gravity-actuated ball-headed shaft presents the advantages of low cost, convenience of assembly, and avoids high failure rates resulting from the complex components in the device.
