Rural water supply system adopts the non-tower pressure-charged water supply device, and drawback of this water control device is that the control contact of electric connecting pressure gauge is easy to ablate,thus thepressure will get out of control.This example describes the agricultural non-tower pressure-charged water feeder,and the control circuit adopts l2V DC voltage power supply, and the current through control contact of electric connecting pressure gauge is small,thus can avoid the control contact erosion.The circuit is stable and reliable,and production costs is low. 　　The principle of circuit　　This agricultural non-tower pressure-charged water feeder circuit is formed by the power circuit and the detection control circuit,which is shown in figure 4-152.
