Accompanying drawing explanation
Fig. 1 is the structural representation of the differential control switch of current provided by the invention;
Fig. 2 is the mounting structure schematic diagram of the differential control switch of current provided by the invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, the differential control switch of current provided by the invention comprises housing 1, housing 1 comprises the upper and lower casing 11,12 of arranging up and down, housing 1 is provided with upper and lower opening 13,14, upper shed 13 is communicated with the water inlet pipe of watering equipment, under shed 14 is communicated with the outlet pipe of watering equipment, and the watering equipment in the present invention is water heater.
In housing 1, be provided with the diaphragm 2 of level, the centre of diaphragm 2 is disc-shaped, outside is crooked flexible face 21, the material of diaphragm 2 is rubber, the edge of flexible face 21 is fixed on the medial surface of housing 1, diaphragm 2 is upper and lower two parts by the spatial separation in housing 1, and two parts completely cut off relatively, and diaphragm 2 can move down under hydraulic pressure pressure reduction.
The below of diaphragm 2 is provided with the moving plate 3 of a downward opening round cap shape, and moving plate 3 can move up and down, and diaphragm 2 is resisted against on the end face of moving plate 3, in moving plate 3, is provided with magnet 4, and magnet 4 bottoms are against there being compression spring 5.The inner shield sheet 8 that is fixed with shielded magnet 4 magnetic fields on the lateral surface of moving plate 3, inner shield sheet 8 is annulus sheet and concordant with the bottom surface of magnet 4.
Magnet 4 belows are provided with the riveted circle 6 in its magnetic field of shielding, riveted circle 6 is fixed on housing 1 and top is cylindric, bottom is annulus sheet, riveted circle 6 is fixed as one with upper and lower casing 11,12, riveted circle 6 belows are provided with the magnetic switch 7 of controlling watering equipment folding, magnetic switch 7 is fixed on housing 1, and magnet 4 moves down through acting on magnetic switch 7 after riveted circle 6.
