Abstract

The utility model provides a new fluid level gauge, comprising a liquid level barrel, a magnetic floating ball, a dial, a barrel cover, etc. The utility model is characterized in that the inner of the dial is provided with a guide slot, an indicating needle, and a signal transducer. When the liquid level changes, the magnetic floating in the liquid level barrel ball is followed to change. Under the action of a magnetic force, the indicating needle of the dial is caused to change in the guide slot, and an actual liquid level state is indicated. A signal transducer can transmit the liquid level signal to a voice circuit to inform the liquid level state; when the liquid level is high or is low, the attention of liquid level is high or liquid level is low is informed through the voice circuit to remind operators to notice. The utility model has the advantages of novel structure, easy assembly, good using effect, avoidance of wrong indication, voice function of informing liquid level state in time, and service life extending.

Description

New fluid level gauge

The utility model relates to a kind of liquid level gauge.

Existing a kind of liquid level gauge, mainly by fluid level tube, magnetic floating drum, the double-colored bead of magnetic, and liquid level indicating graduation plate is formed.When the liquid level change in the fluid level tube, the magnetic floating drum changes, owing to utilized the two magnetic bodies principle of " same sex is repelled each other, and there is a natural attraction between the sexes ", made that the double-colored bead of magnetic overturns one by one under magneticaction, indicate liquid level, if but in use assemble improperly, and or be subjected to the influence of its environment to make magnetic force weaken, bead can not overturn, can not correctly indicate actual liquid level, cause the mistake indication.

Be the shortcoming of avoiding above-mentioned original technology to exist, the utility model provide a kind of novel structure, result of use good, can correctly indicate actual liquid level, have voice informing actual liquid level state and high and low level alarm function simultaneously, the novel liquid level meter of long service life.

The purpose of this utility model is achieved in that by fluid level tube, ball float, magnet, cover, O-ring seal, signal transducer, gathering sill, pointer, indicating graduation plate forms liquid level gauge.Of the present utility model being characterised in that has gathering sill, pointer, signal transducer and indicating graduation plate.When liquid level change, the fluid level tube inner float ball changes thereupon, owing in the ball float magnet is housed, pointer under magneticaction in the indicating graduation plate also and then changes in gathering sill, can correctly reflect actual liquid level, simultaneously, signal transducer is sent to sound circuit by telling present fluid level condition by button with liquid level signal, when liquid level reaches high or low, can tell " noting the liquid level height " or " noticing that liquid level is low " to remind operating personnel to note in time.

Description of drawings is as follows:

Fig. 1 is the structural representation of novel liquid level meter;

Fig. 2 is an indicating graduation dish structural representation;

Fig. 3 is voice, warning circuit block diagram.

Below in conjunction with accompanying drawing the utility model is further described: referring to Fig. 1, Fig. 2, liquid level gauge is made up of fluid level tube (1), ball float (2), magnet (3), index dial (4), cover (5), O-ring seal (6), gathering sill (8), scaleplate (9), pointer (10), signal transducer (11).Feature of the present utility model is to be provided with gathering sill (8) in index dial (4) inside, pointer (10), signal transducer (11), during assembling, with magnet (3) ball float (2) inner sealing of packing into, ball float (2) is put into fluid level tube (1), putting O-ring seal (6) seals fluid level tube (1) with cover (5), put into pointer (10) in the gathering sill (8) with index dial (4), load onto signal transducer (11), with indicating graduation plate (9) good seal index dial (4), at last, index dial (4) is fixed to fluid level tube (1) outside, thereby constitutes liquid level gauge.

The utility model compared with prior art has the following advantages: novel structure, result of use be good, avoid the mistake indication, with phonetic function, in time informs fluid level condition, increases the service life.

Claims
