A communicating valve is arranged on the tubular liquid level meter, and simultaneously, a seal pipe floater is arranged in the tubular liquid level meter; a magnet is arranged in the seal pipe floater; the seal pipe floater can slide in the tubular liquid level meter; and reed pipes are arranged at the exterior of two ends of the tubular liquid level meter and are connected with a liquid level status indicating circuit simultaneously. The novel liquid level detector does not pollute liquid, is high in detection accuracy, wide in the range of applicable temperature, high in safety, strong in corrosion resistance and low in cost, and is simple to manufacture, easy to popularize and simple and convenient to install.
Description
Technical field
The utility model relates to the level gauging field, especially a kind of novel liquid level pick-up unit.
Background technology
The liquid level detection device of widespread use in the market mainly contains two kinds of float-ball type pick-up unit and electric pole type pick-up units, and wherein mainly there is following problem in the float-ball type pick-up unit:
1, low precision.Floating-ball level switch depends on the position of ball float and since liquid rock ball float running orbit poor repeatability; Low precision.
2, Applicable temperature is low.Present megathermal float-ball type pick-up unit mostly is water shutoff silver in the stainless steel casing greatly, loses efficacy because the mercury expanded by heating easily causes detecting;
3, easily twine.Because float-ball type pick-up unit afterbody has cable, easy and other object twines.Mainly there is following problem in the electric pole type pick-up unit:
1, contaminated liquid.Owing to have electric current to pass through in the testing liquid, the electrolyte in the testing liquid can producing electrolysis between electrode effect, influences the composition of testing liquid, causes the testing liquid pollution.
2, low precision.The electric pole type pick-up unit detects two resistance between electrode, and liquid component has determined the conductance of liquid, in actual the use because the change of liquid component, two interelectrode resistance dynamic changes, and switching threshold is fixed, so low precision.
Electric leakage takes place and causes peril, so all there is the problem of poor stability because all charged and be positioned at liquid internal in above-mentioned two kinds of pick-up units easily; Owing to the influence of fouling and galvanic corrosion, the electrode of the shell of float-ball type pick-up unit and electric pole type pick-up unit is corroded easily simultaneously, and serviceable life is short.
The utility model content
The utility model technical assignment is at not enough in the above-mentioned technology, and the novel liquid level pick-up unit is provided.
The utility model technical solution technical scheme that problem adopts is: the novel liquid level pick-up unit, comprise the tubular type liquid level gauge, on described tubular type liquid level gauge, be provided with communicating valve, in described tubular type liquid level gauge, be provided with the sealed tube float, be provided with magnet in the described sealed tube float, and all be provided with tongue tube in outside, tubular type liquid level gauge two ends, described tongue tube is connected with the liquid level indicating circuit simultaneously.
Described sealed tube float can slide in the tubular type liquid level gauge, and described sealed tube float is a sealed glass tube, and described tubular type liquid level gauge is a glass-tube liquid level meter.
Described magnet is a magnet steel.
Described liquid level indicating circuit is the series circuit that power supply, tongue tube, slide rheostat and pilot lamp constitute.
The beneficial effect that the utility model can bring is:
1, precision height.The sealed tube float leads through the tubular type liquid level gauge, the position good reproducibility, and the magnet steel that plays detection effect does not contact with liquid, and the composition of liquid does not influence testing result, therefore has very high precision.
2, broad application temperature range: the lowest temperature that can survey, by the solidifying point decision of liquid, by selecting different magnet steel, the highest survey to about 900 ℃.
3, simple installation, safe.The utility model is installed in external container, and installation process is simple, and the sealed tube float that contacts with liquid is a passive element, can be used on deep-etching or has in the harsh measurement environment of requirement of explosion proof.
4, resistance to corrosion is strong, and is pollution-free to liquid.Because the sealed tube float material that contact with liquid is a glass, except with minority chemical reaction such as hydrofluorite not with other chemical reaction, so can not impact liquid component to be measured.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As depicted in figs. 1 and 2, the utility model provides a kind of novel liquid level pick-up unit, comprises tubular type liquid level gauge 1, is provided with communicating valve 2 on described tubular type liquid level gauge 1, is connected with testing liquid 3 place containers.In described tubular type liquid level gauge 1, be provided with sealed tube float 4, sealing pipe float 4 is sealed glass tubes, the sealed tube of this material except with minority chemical reaction such as hydrofluorite not with other chemical reaction, therefore can not impact testing liquid 3 compositions.
Described sealed tube float 4 can slide in tubular type liquid level gauge 1, described, described tubular type liquid level gauge 1 is a glass-tube liquid level meter, be provided with magnet 5 in the described sealed tube float 4, magnet 5 positions are liquid level line, described magnet 5 is magnet steel or other kicker magnets, the selection of concrete magnet 5 materials, needs according to testing liquid 3 temperature, make the Curie point of magnet 5 be higher than the liquid maximum temperature of surveying, magnet 5 plays magnetization tongue tube 6, and all is provided with tongue tube 6 in outside, tubular type liquid level gauge 1 two ends, and described tongue tube 6 is connected with by power supply 9 simultaneously, tongue tube 6, the liquid level indicating circuit that slide rheostat 7 and pilot lamp 8 series connection constitute.
During concrete the use, too high when liquid level, sealed tube float 4 is magnetized it just near upper end tongue tube 6, script normal open switch closure, and the pilot lamp 8 on the tongue tube 6 liquid level indicating circuits of living in brightens by often going out accordingly, plays the too high indicative function of liquid level.In like manner, cross when low when liquid level, the tongue tube 6 and the liquid level indicating circuit of lower end also can play same effect.Below tubular type liquid level gauge 1, also be provided with blowoff valve 10.
The utility model precision height, broad application temperature range, simple installation, safe, resistance to corrosion is strong, and is pollution-free to liquid, makes easily, with low cost, promotes easily.
