Water Solenoid Valve for Garden Irrigation
Garden landscape can beautify the environment and adjust the ecological balance. Currently, it is playing a more and more important role in urban construction. Maintenance of garden landscape requires a complete set of greening and irrigation system. Various water-saving design measures should be adopted for the garden greening and irrigation design. The following part mainly introduces the water-saving garden greening and irrigation design measures.
A good irrigation system, without a complete set of control system, can hardly achieve the water-saving effect. Generally, the irrigation system relies on the advanced control system to save its water. In the control design, the water systems can be divided into different control units according to different regions and devices, such as the lawn spray irrigation, shrub drip irrigation area, shrub spray irrigation area. The same irrigation area is controlled by one solenoid valve. The solenoid valve usually ranges from DN25 to DN50. Then, the solenoid valve is divided into several irrigation groups according to the water supply capacity of the main supply water pipe. Irrigation by turns can be adopted to reduce the main pipe diameter and reduce the pipeline investment cost.
The opening and closing of the solenoid valve are controlled by the irrigation controller. The 220V low-voltage power source (or the alkaline dry cell: 12V DC or 24V DC) provides the electricity for the irrigation controller and is equipped with the independent operation program itself. Every program can set up four starting time points. The management personnel can set different starting time and irrigation postponement time according to different control regions and plant irrigation demands. The end lead of the irrigation controller is connected with a rain sensor. In terms of spray irrigation, when it rains and the precipitation reaches certain level, signals are transmitted to the irrigation controller. The irrigation controller can send out instructions to automatically turn off the irrigation system, and put off the next irrigation. This can effectively avoid further irrigation by the rain water and achieve the purpose of saving water resources.
