Abstract
The utility model relates to a spiral line type steel tape liquid level meter, which is characterized in that a cylindrical tape reel is coiled up with a steel tape, the medial axial line of the steel tape is formed into a spiral line, and a float is directly suspended at the lower end of the steel tape. The utility model can obtain the projected length of the steel tape and the height of the liquid level by measuring the rotation angle of the steel tape reel, the diameter of the steel tape reel, and the thickness of the steel tape according to an angle sensor of the spiral line type steel tape liquid level meter. The utility model can normally operate without the influences of liquid level intensity and instrument impact. The utility model has the advantages of simple structure and strong reliability. The height of the liquid level is calculated accurately and conveniently.
Description
Technical field: the utility model relates to level gauging instrument technical field, belongs to a kind of device of the steel band measuring liquid level of helical type specifically.
Background technology: the liquid level that existing market provided is in respect of a lot of forms, wherein level gauge of steel band is with perforated steel ribbon and stirs the corner of counting ratchet as principle of work measuring liquid level height, as shown in Figure 1, perforated steel ribbon S length is worn an aperture, on counting ratchet 3 circle diagrams several sour jujube pins 2 are arranged, perforated steel ribbon moves S * n length is rotated a week for the counting ratchet length, thereby but measurement count ratchet rotational angle can be calculated steel band and emitted length, it is the height of liquid level, above-mentioned liquid level Calculation Method obtains liquid level, the key request under any circumstance aperture on the steel band should accurately pierce into sour jujube pin 2, this not only increases the resistance of motion descends the sensitivity of instrument, if aperture is worn to advance the main hidden danger that sour jujube pin 2 will cause instrument fault, when liquid level gauge big ups and downs or instrument withstand shocks, aperture and sour jujube pin 2 more are difficult for piercing into, and make the instrument can not reliability service.
The purpose of this utility model provides and a kind ofly produces big ups and downs or instrument is subjected under the bigger impact condition when liquid level, all can make the instrument reliability service, simple in structure and the hidden danger of all faults can not occur, improve a kind of helical steel band of model liquid level gauge of fiduciary level greatly.
For finishing the technical scheme that above-mentioned purpose is taked: coil steel band on the above-mentioned cylindrical machine reel, the axis of steel band forms a helical, and the steel band lower end is directly suspended float in midair.
Perforation and counting ratchet on the utility model cancellation steel band custom steel band, simplify instrument structure, eliminate instrument and cause fault, improve the fiduciary level of instrument because of liquid level big ups and downs or instrument withstand shocks, the counting of helical length is finished by gauge internal monolithic movement simultaneously, the convenient and high feature of precision.
Description of drawings:
Fig. 1 is a correlation technique structural drawing of the present utility model;
Fig. 2 is the utility model structural drawing.
Embodiment: the utility model is further described according to Fig. 2, above-mentioned axle 8 two ends connect machine reel 7 and constant force spring 4, the setting of constant force spring is played and is tightened up the tension effect of steel band 5 when stretching out or shrink, and makes constant force spring produce an equilibrium of forces effect to steel band.Coiling steel band 5 on the cylindrical machine reel 7,
Invar band 5 has a thickness, and the axis of steel band 5 forms a helical, and steel band 5 lower ends are directly outstanding
Hang float 6, remove habitual counting ratchet between steel band suspention float 6.
The liquid level of above-mentioned liquid level gauge can be according to the following manner gained:
If the extension elongation of steel band 5 is that the starting point of L, liquid level is A to the height of machine reel axle point, then liquid level H=A-L.
If during L=0, steel belt disk corner=0, then helical length is BO, when steel band 5 extension elongations are L, the steel belt disk corner is Q, then helical length is BL.
The angular transducer of liquid level gauge is measured the thickness T of steel belt disk corner Q, steel belt disk 7 diameter D, steel band 5, draws BO, BL, then draws the height H of steel band 5 extension elongation L and liquid level.
