Electric self-generating self-controlling watermeter valves

The utility model provides an electric self-generating self-controlling watermeter valve which belongs to water control equipment field. The utility model adopts a paddle-wheel superminiature self-generating system (7) together with the kinetic energy arising from the flow of consumption water to generate electricity. An electric self-controlling valve (1) has a switch mechanism (6) controlled by a micromotor (5) and a radio remote control switch system (8), moreover, the power supply is provided by the self-generating system (7); the utility model has the advantages that: the electric self-controlling valve (1) is supplied with the power supply and the valve can control the switches remotely, thereby, providing the preconditions for the measures of automatic metering and remote control; the valve is safe with no need to check meters indoors, thereby solving the problems that the administration department fail to control the users who refuse to pay for water or exceed the standard, contributing to education and compulsion of the users to observe water rules and regulations and to save water self-consciously, strengthening and standardizing the water management, saves manpower and material resources, and is advantageous to the country and the people.
