It turns round in rotary motion trace, the aperture of through-hole is greater than the spring silk outer diameter of torsional spring.
The principles of the present invention are, when liquid level rising reaches warning liquid level, and the sliding of the first floating ball is unsmooth, by the
Two floating balls float the button of pressing microswitch, and then alerted by the external circuit for microswitch contact of ining succession outside (such as
The switching value that microswitch is inputted as PLC).In order to be suitable for the liquid of different densities, using passing through bending on torsional spring
Cooperate from different through-holes to adjust the mode of torsional spring, without making this liquid-level switch more by the way of adjusting the second floating ball weight
It is flexibly practical.
Further, the tail end of the connecting rod is connected with the pressing plate of outer convex.The structure ensures reliably to press fine motion
The button of switch.
Further, the first end of the torsional spring is fixed in connecting rod.
Further, between the rotation axis of the connecting rod and the second floating ball partially include casing and extension rod, extension rod
