[embodiment]
Below in conjunction with accompanying drawing technical solutions of the utility model are elaborated.
As depicted in figs. 1 and 2, the utility model float-type liquid-level switch comprises liquid-level switch module 1, mounting panel 2, guide pin bushing 3 and floating drum 4, mounting panel 2 has one and goes up perforate and a following perforate, last perforate is relative with following perforate and lay respectively at the top and the bottom of mounting panel 2, liquid-level switch module 1 is inserted in the mounting panel 2 by last perforate, liquid-level switch module 1 is positioned on same the center line with floating drum 4, floating drum 4 is slidingly connected with guide pin bushing 3, floating drum 4 can be up and down along guide pin bushing 3, and guide pin bushing 3 is fixed on down in the perforate.
In optimal technical scheme of the present utility model, the utility model float-type liquid-level switch is installed on the PVC (polyvinyl chloride) or polypropylene cell body of horizontal production line.
In optimal technical scheme of the present utility model, as shown in Figure 3, liquid-level switch module 1 comprises liquid-level switch main body 11 and magnetic level transducer 12, and magnetic level transducer 12 is fixed on the below of liquid-level switch main body 11.Liquid-level switch module 1 also comprises thrust 13, and thrust 13 is fixed on the liquid-level switch main body 11, and the external diameter of thrust 13 prevents like this that greater than the internal diameter of last perforate liquid-level switch module 1 from dropping in mounting panel 2.Liquid-level switch module 1 adopts common liquid-level switch, and the magnetic level transducer is used for the induction level height.
