Constant current control method
The invention relates to a constant flow control method. The constant flow control method comprises the steps that water flow is output from one of a plurality of output sections of a waterway; in at least one output section, the water flow passes through a balance damping hole before passing through a spray hole of the output section, and the sum of water resistance values of the spray hole and the balance damping hole is within a preset water resistance range; and the pressure drop value of the water flow passing through each output section is within a preset pressure drop range. Although different spraying holes have different water resistance values, the balance damping holes are formed in the output sections, and the sum of the water resistance values of the spraying holes and the water resistance values of the balance damping holes is within the preset water resistance range, so that the different output sections have similar water resistance values. And the pressure drop value of the water flow passing through each output section is within the preset pressure drop range, so that the water flow can generate water columns with different shapes when passing through different output sections, and meanwhile, the consistent flow can be kept when passing through different output sections.
本发明涉及一种恒流控制方法，恒流控制方法包括步骤：水流从水路的多个输出段的其中一个输出；在至少一个所述输出段中，所述水流通过所述输出段的喷孔前还通过平衡阻尼孔，所述喷孔与所述平衡阻尼孔的水阻值之和均处于预定水阻范围内；所述水流在经过各个所述输出段时的压降值均处于预定压降范围内。尽管不同的喷孔具有不同的水阻值，但通过在输出段内设置平衡阻尼孔，且喷孔的水阻值与平衡阻尼孔的水阻值之和处于预定水阻范围内，能让不同的输出段内具有相接近的水阻值大小。又由于水流在经过各个输出段时的压降值均处于预定压降范围内，从而能让水流在通过不同的输出段产生不同形状的水柱，同时经过不同的输出段时能保持一致的流量。
