動弁開閉装置を提供することを目的とする。In conventional electric valve opening and closing devices, an AC motor is used instead of a DC motor as the means for opening and closing the valve device. However, this device uses an AC motor instead of a DC motor. Since it is a power source, three electric wires are required for power supply.
·Ta. For this reason, when this electric valve opening/closing device is used for field irrigation, the distance from the power source to the device is long and three electric wires are required, making it uneconomical. In addition, in the event of a power outage, the motor-operated valve will maintain the opening position it had before the power outage and will lose its opening/closing function, so depending on the application it is necessary to prepare an emergency power source, had the problem that the equipment cost was high and it was uneconomical.In order to solve this problem, a patent application was filed on February 30, 1989!;
) has proposed a "method for opening and closing electric valves, etc." using a DC motor as the electric motor, but the present invention further improves the limit switch and provides an economically advantageous electric valve opening and closing device with a simplified structure. The purpose is to provide
