The device has the advantages that the operation is simple and convenient, the reliability is high, the power consumption and cost are low and the maintenance and management are facilitated; the device is suitable for the automatic control of large-scale drip irrigation and independent control.

Description

technical field [0001] The invention relates to an electric valve device equipped with a double-axis motor for a manual internal lift cut-off valve. Background technique [0002] Due to the scarcity of water resources and the prominent contradiction between water and soil, the promotion of water-saving irrigation technology has become a top priority. At present, the following phenomena exist in the use of artificial drip irrigation: [0003] 1. The area of ​​the irrigated land is too large and too wide. The use of manual drip irrigation management is time-consuming and laborious, and the efficiency is very low. If the management is not in place, the irrigation time cannot be managed according to the specified time, especially at night, hot weather, and other unforeseen reasons. Mastering the irrigation time cannot meet the needs of scientific irrigation; [0004] 2. It is impossible to further improve the modern management level of the existing water-saving irrigation agri...

AI Technical Summary

Problems solved by technology

[0003] 1. The area of ​​the irrigated land is too large and too wide. The use of manual drip irrigation management is time-consuming and laborious, and the efficiency is very low. If the management is not in place, the irrigation time cannot be managed according to the specified time, especially at night, hot weather, and other unforeseen reasons. Mastering the irrigation time cannot meet the needs of scientific irrigation;

[0004] 2. It is impossible to further improve the modern management level of the existing water-saving irrigation agriculture;

[0005] 3. It is impossible to quickly and conveniently obtain the emergencies of on-site equipment and irrigation;

[0006] 4. Due to the lack of water resources and other issues, manual irrigation management is used, and water-saving measures cannot be implemented accurately and efficiently

Disadvantages: There is a control intermediate station, the valve cannot be opened when the water pressure is low, the power consumption of the two-way radio for sending and receiving is high, resulting in high application prices, and most valves cannot work in the next irrigation period; 2. The computer is wired to control the national standard electric valve, using a computer communication network control

Disadvantages: the cost of network cables in the field is high and difficult to maintain, the power consumption of electric valves is large, and the cost is high, resulting in a corresponding increase in the cost of batteries and solar energy

[0009] The price of the traditional Φ90~Φ100mm electric valve is relatively high, the price is about 3,000 yuan. Due to the complex structure, the maintenance cost is high, and it is not conducive to maintenance. Most of them cannot work normally in the second irrigation period.
