Water magnetizing device for farmland pipe irrigation

The utility model relates to equipment for farmland irrigation, and particularly relates to a water magnetizing device for farmland pipe irrigation. The water magnetizing device comprises a shell, a magnetizing device and fixing bolts, wherein the shell is composed of a pair of reducer unions; the magnetizing device is composed of two blocks of parallel magnetic materials which are respectively fixed at two sides inside the shell through the fixing bolts and parallel to the axis of the shell. The magnetizing device disclosed by the utility model is composed of two blocks of parallel magnetic materials which are respectively fixed at two sides inside the shell through the fixing bolts, the direction of a magnetic line is vertical to the direction of water flow; ordered orientation arrangement is carried out on a hydrone structure when irrigation water passes through the magnetizing device, so that a hydrogen chain is snapped, a chain angle deforms, the association degree of water is reduced, the polarity is enhanced, and a water cluster is reduced and easily penetrates through a semitransparent film of a cell. Thus, transportation and utilization of nutrient substances are improved, and growth of crops is facilitated. The water magnetizing device is simple in structure, reasonable in design, economic and practical, and applicable to pressure pipe irrigation of an agricultural field.
