By the screw-driven between nut 4 and push rod 6, the O RunddichtringO in push rod 6 upper end flange is pressed into sleeve 3, then by ring
Shape Magnet is embedded in float by the slot on float, then the two is inserted in from push rod 6 lower end, by dovetail hook and pushing away
The external screw thread lower surface of bar limits the stroke up and down of float, the wherein center of the tongue tube 9 within push rod 6, the distance outer spiral shell of push rod 6
The height of stricture of vagina lower surface is equal with the half of float 10 axial height.
Nut is made often to rotate 60 degree to push rod by the projection 19 of nut and three spacing preiections 14 of push rod outer surface
Highly it is adjusted 0.5mm, thus can realize the accurate adjustment reported to the police highly, and by the screw thread of nut bottom and push rod
Threaded engagement forms height latch functions.
Use middle push rod 6 the most fixing, liquid level detected to moving up and down along push rod shaft by float 10:
When float 10 falls, its internal annular magnet 11 is not in tongue tube 9 center so that tongue tube 9 place
Liquid level circuit unit open circuit, wiring harness interface 16 outfan for disconnect so that the warning of inventive sensor external connection
Circuit is reported to the police.
When float 10 rises to tongue tube 9 center under liquid level effect, as shown in Figure 3 and Figure 4, tongue tube 9 place
Liquid level circuit unit conducting, wiring harness interface 16 outfan for conducting so that the warning of inventive sensor external connection
Circuit is not reported to the police.
Thus, the present invention can mate multiple series fluid reservoir, it is possible to decrease product development cycle and cost, and has structure
Design uniqueness, length in service life, the dependable performance advantage such as stably.
