Specific embodiment
Specific embodiment of the present utility model is described with reference to the accompanying drawing.
As shown in Figure 1, dual control liquid-level switch, including cylinder 1, floating ball 2 and guide rod 3；Along cylinder there are two being set in cylinder 1
1 inductor being axially distributed, 1 lower end of cylinder are connect with mounting flange 4,3 lower end of guide rod be arranged with floating ball 2, upper end be equipped with can
The touch control component 6 of inductor is triggered, touch control component 6 is located in cylinder 1 and 6 lower end of touch control component passes through balancing spring 5 and installation
Flange 4 is fixedly connected, and floating ball 2 drives guide rod 3 and touch control component 6 to move back and forth along 1 axially reciprocating of cylinder.
Touch control component 6 is magnetic slider, and two inductors are upper inductor 7 and lower inductor 8, and upper inductor 7 includes upper
Rocker arm body 9 and upper limit microswitch 10,9 upper end of upper rocker arm mechanism and upper limit microswitch 10 connect, upper rocker arm
9 lower end of mechanism is equipped with magnet 11 and is fixedly connected by tension spring 12 with cylinder 1, and lower inductor 8 includes lower shake-changing arm mechanism 13 under
Position limited inching switch 14,13 lower end of lower shake-changing arm mechanism and lower limit microswitch 14 connect, and 13 upper end of lower shake-changing arm mechanism is set
There is magnet 11 and is fixedly connected by tension spring 12 with cylinder 1.Magnetic force transmission is eliminated to be transmitted by mechanical device bending motion
Bring fatigue damage, prolongs the service life.
3 lower end of guide rod is fixed with upper limit position block 15 and lower position block 16 by limited screw, and floating ball 2 is located at upper limit
Between block 15, lower position block 16.The position of setting two position can be facilitated, need to only unclamp upper limit position block 15 and lower position block 16
Block screw is limited, corresponding position is moved on to and tightens limit block screw again.
Working principle of the utility model is: magnetic slider is fixedly connected with guide rod 3, floating ball 2 can be as guide rod 3 be in cylinder
It is slided up and down in body 1.When liquid level is at middle position, 2 free floating of floating ball does not contact upper limit position block 15 and lower position block 16,
Magnetic slider and guide rod 3 are maintained at middle position under the elastic force effect of balancing spring 5.Upper rocker arm mechanism 9, lower shake-changing arm machine
Structure 13 is detached under 12 pulling force effect of tension spring with upper limit microswitch 10, lower limit microswitch 14, upper limit microswitch
10, lower limit microswitch 14 disconnects, no signal.
When liquid level drops to lower position block 16, floating ball 2 is contacted with lower position block 16, and the gravity of floating ball 2 is greater than equilibrium bomb
The elastic force of spring 5 pushes guide rod 3 that magnetic slider is driven to move down.When being moved to lower 8 position of inductor, magnetic slider attracts
Magnet 11 in lower shake-changing arm mechanism 13, lower limit microswitch 14 act, and issue liquid level low signal.
When liquid level rises to upper limit position block 15, floating ball 2 is contacted with upper limit position block 15, and the buoyancy of floating ball 2 is greater than equilibrium bomb
The elastic force of spring 5 pushes guide rod 3 that magnetic slider is driven to move up.When being moved to 7 position of inductor, magnetic slider attracts
Magnet 11 in upper rocker arm mechanism 9, upper limit microswitch 10 act, and issue liquid level high RST.
