149 can push magnet sleeve 144 to be moved to the left according to suffered hydraulic coupling.
Specifically, diaphragm 149 lateral surface induction it is hydraulic when be divided into two kinds of situations, the first is, when diaphragm 149 by
When external hydraulic active force is greater than magnetic force (suction between permanent magnet 145 and adjustment ring 147), diaphragm 149 is to 150 indent of cavity
It falls into；It is for second, when diaphragm 149 is less than or equal to magneticaction by external hydraulic active force, 149 outwardly convex of diaphragm.
So, implementation principle of the invention is:
As depicted in figs. 1 and 2, when the water abundance in pond or water tank, outside liquid is flowed by diaphragm lid strainer 152
Enter in diaphragm lid 151, a hydraulic coupling can be applied to diaphragm 149, diaphragm 149 incudes the height of the hydraulic size namely liquid level
It is low that (according to the calculation of pressure formula of water in container: hydraulic pressure=water density gravity acceleration x high, the density value and gravity of water add
Velocity amplitude is fixed, then liquid is higher, then hydraulic pressure is bigger), then pressure is passed into diaphragm axis 148,148 stress of diaphragm axis can push away
Dynamic magnet sleeve 144 is mobile toward the left side, at this point, due to having magnetic between the permanent magnet 145 in magnet sleeve 144 and adjusting ring 147
Gravitational attraction effect, adjusting ring 147, which can turn right magnet sleeve 144, to be retracted, so, can magnet sleeve 144 be moved to the left, and just take
Certainly the suction size of magnet sleeve 144 compared with ring 147 is adjusted in the hydraulic thrust size that diaphragm 149 transmits, such as Fig. 1 institute
Show, when external liquid level is higher, diaphragm 149 is adjusted by biggish hydraulic thrust so that the thrust for being subject to magnet sleeve 144 is greater than
When saving the suction between ring 147 and permanent magnet 145,144 envelope bobbin 148 of magnet sleeve is pushed into left end, before magnet sleeve 144
The permanent magnet 145 at end blocks leader channel 107, at this moment, arrival end further through magnetic force drive pilot valve 108 to left end
Water in 101 can be flowed into first guide cavity 105 by one-way sealing seal 106, increase the liquid in first guide cavity 105, and pressure is reinforced,
Under the pressure of liquid pushes jointly in the thrust of pilot valve 108 and first guide cavity 105, piston body 104 is pushed to left end, and
Seal valve seat 112 is withstood, sealing pair is formed, thus the interface channel of arrival end 101 and outlet end 102 in closed valve 100,
Control valve is in close state, and the water of arrival end 101 cannot flow into pond or water tank.
When water tank or the liquid level in pond decline, as shown in Fig. 2, be subject to hydraulic smaller of diaphragm 149 or not having
When, diaphragm axis 148 is transmitted to the thrust of magnet sleeve 144, less than permanent magnet 145 and adjusts the suction between ring 147, magnet set
Cylinder 144 will be pulled, meanwhile, under the magnetic force, permanent magnet 145 will drive pilot valve 108 to move right, to open elder generation
Conduit logical 107, when the unlatching of leader channel 107, then, the liquid in first guide cavity 105 will be flowed out from leader channel 107, and be passed through
