Specific implementation mode
Technical scheme of the present invention is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of cartridge type liquid level magnetic sensor of the present invention, including float tube 1 and floating ball 11, floating ball 11
It is interior to be equipped with permanent magnet 12, it is packaged with the magnetic switch 13 coordinated with permanent magnet 12 in float tube 1；During 1 upper end of the float tube is connected with
Empty anti-wave cylinder 2, floating ball 11 can be arranged in up and downly in anti-wave cylinder 2, are offered on the side wall of anti-wave cylinder 2 and several are engraved hole
21, several holes 21 of engraving are spaced and be evenly distributed in the movement locus section of floating ball 11；The anti-wave cylinder 2 surrounds floating ball
11 pairs its constitute the blocking of lateral ripples dynamic stress, avoid floating ball 11 from being caused partially to float tube 1 by more lateral impact loadings
Oblique stress, water level pass in and out from anti-2 lower port of wave cylinder and generate buoyancy to floating ball 11, and the permanent magnet 12 in it is made to move up and down to trigger
Magnetic switch 14；And after the transverse load that anti-wave cylinder 2 is born is transmitted to 1 upper end of float tube, lateral torsion is degraded to reduce
Influence to float tube 1 and apparatus connecting unit improves the bonding strength of float tube 1 to improve the job stability of sensor；We
Preferably with 21 array of hole is engraved, engrave 21 array of hole allows flow to pass in and out and generates to wash away swashing for floating ball 11 anti-2 side wall of wave cylinder case
Stream, these make floating ball 11 generate vibration by engraving the guiding flow in hole 21, and avoiding it from being blocked with anti-wave cylinder 2 or float tube 1 causes to pass
Sensor fails.
