Description of drawings
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 made detailed explanation.
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 among the present invention is water heater.
Be provided with the diaphragm 2 of level in the housing 1, the centre of diaphragm 2 is disc-shaped, the 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 with the spatial separation in the housing 1 be about two parts, two parts completely cut off relatively, 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, is provided with magnet 4 in the moving plate 3, and magnet 4 bottoms are against compression spring 5 is arranged.Be fixed with the inner shield sheet 8 in 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 the housing 1 and top is cylindric, the bottom is the 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 control watering equipment folding, magnetic switch 7 is fixed on the housing 1, and magnet 4 acts on magnetic switch 7 after moving down and passing riveted circle 6.
