The column float-type water level sensor comprises a column 1, a reed switch 2, floats 3 and magnets 4, and is characterized in that the reed switch 2 is fixedly installed inside the column 1, and the installation height of the reed switch 2 is a corresponding water level height; every float 3 is a hollow float with a central through hole 11; every magnet 4 is arranged at the hollow part 12 of every float 3; and the column 1 penetrates through the central through holes 11 of the floats 3. The water level sensor solves the large size problem of stainless steel floats and foamed plastic floats, the corrosion problem of aluminum alloy floats in water, and the clamping stagnation problem of the floats caused by water film tension; the structure is simple; the technology is mature; the reliability is high; and the sensor is already applicable to airplanes, and has a great application value.
Description
Technical field
The utility model relates to filtered water tank level measuring field.
Background technology
Civilian water level fields of measurement is used more column float type water level sensor, and its float is generally stainless steel float or floater of foam.The general volume of stainless steel float and floater of foam is larger, can take this nervous water tank capacity.Measure the column float type liquid level sensor of liquid level on the existing aircraft, its float is the rust-preventing aluminum alloy float, after in water, soaking for a long time, and can electrochemical corrosion.In addition, moisture film tension force can make float be adsorbed on the column, thereby affects the motion of aluminium alloy bob.Therefore, the magnetic induction liquid level sensor of rust-preventing aluminum alloy float is not suitable for the level measuring of filtered water tank.
Summary of the invention
The purpose of this utility model is: solve the larger problem of stainless steel float, floater of foam volume and aluminium alloy bob etching problem and the moisture film tension force problem that causes the float clamping stagnation in water.
The technical solution of the utility model is: the utility model comprises column 1, tongue tube 2, float 3, magnet 4, it is characterized in that: tongue tube 2 is fixedly mounted on column 1 inside, the setting height(from bottom) of tongue tube 2 is the equivalent water level height, float 3 is the hollow float with central through hole 11, magnet 4 is installed in float 3 hollow parts 12, and column 1 passes the central through hole 5 of float 3.Float 3 is hollow housings that got up by lower house 8 and upper cover plate 7 welded seals, and the center pit of float 3 all is welded with lining 9 in both sides up and down.The quantity of float 3 is 3～8.Column 1 is the metal tube of hollow, column 1 one end mounting flanges, and the other end is installed plug 5 and is inserted in the water.
The beneficial effects of the utility model are: simple in structure, and technology maturation, reliability is high, is applied aboard, has larger practical value.

Embodiment
Please refer to Fig. 1, the utility model comprises column 1, tongue tube 2, float 3, magnet 4, wherein tongue tube 2 is fixedly mounted on column 1 inside, the setting height(from bottom) of tongue tube 2 is the equivalent water level height, float 3 is the hollow float with central through hole 11, magnet 4 is installed in float 3 hollow parts 12, and column 1 passes the central through hole 5 of float 3.Tongue tube 2 is installed in column 1 inner equivalent water level height, and is glued.Float 3 is hollow nonmetal float, and magnet 4 sticks with glue the float hollow parts 12 that is connected on float 3.Float 3 passes column 1 by central through hole 11 and can move up and down with water level.When float 3 moved near the tongue tube 2, the magnetic attraction tongue tube 2 of magnet 4, this height of water level signal were converted into electric signal and are delivered to back-end circuit and process and show.
Please refer to Fig. 2, column 1 and plug 5 all adopt stainless steel or aluminium alloy to make, and both carry out vacuum argon arc welding welding and guarantee sealing, stop water to enter column 1 inside.After 5 welding of column 1 and plug, answer polishing welding seams, surface spraying coating 6 outside then, coating material is teflon coating.At last, tongue tube 2 is placed on column 1 inner equivalent water level place, and filler is fixed.
Please refer to Fig. 3, float 3 comprises magnet 4, upper cover plate 7, lower house 8, lining 9 and coating 10.Upper cover plate 7 and lower house 8 and lining 9 all adopt the PPS(polyphenylene sulfide) material.At first, lining 9 and lower house 8 are connected together by supersonic welding, the cross section of lining 9 is trapezoidal.Magnet 4 usefulness high-temperature plastics are bonded in lower house 8 inside.Upper cover plate 7 and lower house 8 are connected together by supersonic welding, and guarantee sealing.After welding was finished, surface spraying coating 10 outside, and coating material is teflon coating.
Because the outside surface at column 1 and float 3 all has teflon coating, teflon coating has hydrophobic nature, non-viscosity, mar proof and corrosion resistance, so this level sensor has possessed decay resistance.Simultaneously, because there is lining 9 float 3 inboards, make float 3 and column 1 Gap-Ratios larger, can't form moisture film.The position that lining 9 contacts with column 1 just may form moisture film, but the tension force of this moisture film is enough to make float 3 to stick on the column 1 far from.Therefore, solved the problem of float 3 generation clamping stagnations.
