Irrigation system winter maintenance--maintenance of valves, filtration systems, fertilization systems, pumps
Valve maintenance
In the winter maintenance of the irrigation system, after draining the water in the pipeline, pay attention to the maintenance of various valves in the system. Because of the structure, especially the structure of the solenoid valve is relatively complicated, the water stored therein is not easy to be completely drained, and it is easy to cause the valve to freeze and crack when placed in the open air without the insulation measures. After the system is drained, the ball valve, gate valve and other valves should be kept open to prevent the local water from freezing and cracking the valve. Valves placed in the open air should be wrapped with antifreeze materials. In the area where the frost damage is serious, if there is no insulation measures, it is necessary to remove the upper valve body of the solenoid valve after the pipeline is drained, and wipe the water inside the solenoid valve with a clean towel....
