Abstract
The utility model relates to a float liquid level indicator. A hollow float inner core is fixed in a hollow float, and a moving and a fixed contacts are arranged in the float inner core. When the moving and the fixed contacts contact each other, two core wires leading a lead out are communicated with each other, and when the moving and the fixed contacts disengage from each other, the two core wires leading a lead out break, so whether the liquid level is in place is reflected. The utility model has the advantages of simple structure, low production cost, convenient installation and operation, long service life, etc., and is especially suitable for liquid level indication of special places.
Description
The utility model relates to a kind of float type liquid level indicator, particularly is characterised in that the liquid level indicator of float structure.
Liquid level indication (sensing) device in the market has tuning-fork type, kinds such as ferromagnetic adhesive hook switch formula, float-ball type, the not only cost that manufacture craft that they have requires high (as tuning-fork type), have higher and also use in to increase the trouble (as magnet adhesive hook switch formula) of cleaning, the volume that has is big, installation complicated (as float-ball type), and improved necessity is all arranged.
The purpose of this utility model is to design that a kind of structure is simple relatively, cost of manufacture is cheap and use float type liquid level indicator very easily.
The utility model contains the hollow floating body 1 with definite geometric configuration, and also attached wall is installed with the hollow floating body kernel 2 that tool is determined geometric configuration in described hollow floating body 1; In the cavity of described hollow floating body kernel 2, be provided with the moving contact of making by optimum conductive material 4 and decide contact 5; Also be provided with twin-core and draw lead 7 in described hollow floating body kernel 2, the exit that described twin-core is drawn lead 7 is fixed on the suitable location of described hollow floating body 1 outer liquid container liquid level top; When described hollow floating body 1 floated on the liquid level, the center of gravity of its contained hollow floating body kernel 2 should be below section among the described hollow floating body 1.
In the specific implementation, described moving contact 4 is the copper billets that can be free to slide vertically in the chamber within above-mentioned hollow floating body kernel 2, and described to decide contact 5 be to be fixedly arranged on a pair of contour of moving contact 4 outsides but the little copper sheet of mutually insulated, and two built-in heart yearn highland barleys ends that described twin-core is drawn lead 7 then are fixed in respectively on the described a pair of little copper sheet.
For make described moving, decide to paste tightlyer when contact is in contact with one another, the utility model can also adopt slightly complicated structure: in the inner chamber of described hollow floating body kernel 2, deviate from described moving contact 4 that a described side of deciding contact 5 is folded establishes a magnet that can be free to slide vertically 3, and decide side outside the contact 5 described, fix a pair of contour and non-touching ferromagnetic material (6) again.
In order to adapt to the violent situation of liquid fluctuating, of the present utility model moving, decide contact and can design more sensitivelyer.Most realistic a kind of scheme is as follows: can think moving contact 4 around the flat copper of fixedly pole 8 rotations in one of magnet 3 outsides hinge joint that can be free to slide vertically in the chamber within hollow floating body kernel 2, and make to decide contact 5 with the flat copper piece that is installed in said fixing pole 8 outsides, two heart yearns of at this moment drawing lead 7 are then realized being electrically connected with above-mentioned flat copper, flat copper piece respectively, simultaneously above-mentioned calmly, side also is installed with at least one block of ferromagnetic material 6 outside the moving contact.
When the utility model floats on the liquid level, because gravitational effect will occur with the attitude shown in the accompanying drawing 1.This moment is moving, decide contact closely contacts, and two heart yearns of drawing lead will be in connected state; After liquid level is backed off, if the space is enough, upset will take place and occur with the attitude shown in the accompanying drawing 3 in the utility model, then moving, decide contact and break away from mutually, draw between two heart yearns of lead and promptly be in off-state.That is to say, draw heart yearn in the lead surperficial liquid level that communicates and floated the utility model, otherwise the explanation liquid level does not put in place.
With existing liquid level indicator relatively, cost of the present utility model is lower, and install and use also quite convenient; In addition, moving because of it, decide contact and all be sealed among the hollow floating body kernel, so need not regular cleaning, mission life is also longer, and the liquid level that is specially adapted to acid, aqueous slkali and the explosion-proof occasion of need is indicated.
Accompanying drawing 1 is the structural representation of a kind of embodiment of the utility model.
Accompanying drawing 2 is A-A cut-open views of accompanying drawing 1.
Synoptic diagram when accompanying drawing 3 is the utility model generation upset.
Accompanying drawing 4 is structural representations of the another kind of embodiment of the utility model.
Among the figure, 1, hollow floating body, 2, the hollow floating body kernel, 3, magnet, 4, moving contact, 5, decide contact, 6, ferromagnetic material, 7, draw lead, 8, fixing pole.
