Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Like Fig. 1, Fig. 2 and shown in Figure 3, the structure of the utility model three fly rod density measurement float comprises annular fly rod support 3, and the ball float 5 of hollow is installed in the endoporus of fly rod support 3, and fly rod support 3 is positioned at the medium position of ball float 5; Be provided with the installation sleeve 12 of tubular in the ball float 5, the sidewall at installation sleeve 12 two ends is connected with the outer wall at ball float 5 two ends respectively, installation sleeve 12 and ball float 5 coaxial settings; Form chamber 13 between installation sleeve 12 and the ball float 5; The magnet ring cover 11 of annular is installed on the sidewall of installation sleeve 12; Be connected with the magnet ring 10 of annular on the magnet ring cover 11; Magnet ring cover 11 all is positioned at chamber 13 with magnet ring 10, magnet ring 10 and installation sleeve 12 coaxial settings, and the axial centre of magnet ring 10 overlaps with the radial center of ball float 5; The sidewall of ball float 5 one ends is provided with the filling sand mouth 8 that communicates with chamber 13, and the mouth mouth of irritating sand mouth 8 is provided with rubber blanket 6 and shutoff screw 7; Ball float support 3 deviates from the end face of irritating sand mouth 8 and is evenly equipped with three fly rods 2, and the axis of the axis of fly rod 2 and ball float support 3 parallels, and an end of fly rod 2 is connected with ball float support 3 through bolt 4, and the other end of fly rod 2 is a free end.
Fly rod 2 employing external diameters are that the hollow aluminum pipe of 5mm is processed, and its length is 1.1m.Fly rod support 3 adopts light material to process, like aluminum or aluminum alloy.Ball float 5 is a spheroid.
When needing the density measure scope of adjustment density float, can accomplish through the overall weight of adjusting this density measurement float.Concrete grammar is: open shutoff screw 7, an amount of plumbous sand 9 is added in the chamber 13 through irritating sand mouth 8, after plumbous sand 9 adds completion, irritate sand mouth 8 with 7 sealings of shutoff screw.The weight that adds the plumbous sand in the chamber 13 can be accomplished through in the sample liquid of known density, repeatedly testing: this density measurement float is placed sample liquid; If it just in time is 1/2nd of fly rod 2 length that fly rod 2 stretches out the length of liquid level; The overall weight adjusted that this density measurement float then is described is good, and its measurement range will depart from 0.05g/cm up and down with the sample liquid density value
3
When measuring canned liquid density, magnetostriction liquidometer sounding rod 1 is penetrated installation sleeve 12, make three fly rods 2 upwards, filling sand mouth 8 is downward; Magnetostriction liquidometer sounding rod 1 and this density measurement float are together put into testing liquid; The liquid level float that magnetostriction liquidometer carries swims on the liquid level; Ball float 5 is immersed in the testing liquid, and is positioned at the below of liquid level float, and a height difference H is arranged between liquid level float and the ball float 5.Because liquid level float sectional area is big, its variation that is immersed in the height in the liquid is very little during liquid density variation; And this density measurement float is in liquid level position is the very little fly rod of sectional area 2, and the variation of fluid density brings the bigger floating displacement of falling can for ball float 5.When fluid density became big, ball float 5 had been with fly rod 2 come-ups, and height difference H reduces; When fluid density diminished, ball float 5 had been with fly rod 2 to sink, and height difference H increases.Ball float 5 drives in fly rod 2 come-ups or the sinking process, and these three float rod type density measurement float move up and down along the axis direction of magnetostriction liquidometer sounding rod 1.Read the H value through magnetostriction liquidometer, background computer software promptly capable of using obtains the correct density of current liquid according to density calculation formula and density correction formula.
The same with traditional density appearance, the utility model density measurement float also is only the liquid in a certain specific density scope to be measured that (for example the density measure scope is 0.69～0.79 g/cm
3), through regulating the weight of this density measurement float, can so that in the upper limit of density measure scope (like 0.79 g/cm
3) time, ball float 5 as close as possible liquid levels and height difference H are as far as possible little; And at the lower limit of density measure scope (like 0.69 g/cm
3) time, ball float 5 is big as far as possible away from liquid level and height difference H as far as possible, and the precision of the big more density measure of height difference H under two kinds of situation is just high more.The length of fly rod 2 is 1.1 meters, and its maximum displacement difference can reach 1 meter, because the displacement resolution of magneto strictive sensor can reach 0.1mm in the magnetostriction liquidometer, so for 0.1 g/cm
3Variable density, can obtain 10000 different readings, at this moment, the minimum resolution of density appearance can reach 0.00001 g/cm
3, and the precision of traditional density appearance is 0.0005g/cm
3When the liquid level of testing liquid changes; But following liquid level one according to the liquid level float that density measure principle knowledge capital density measurement float and magnetostriction liquidometer carry changes; But the height difference H between liquid level float and the ball float 5 does not change, so measuring accuracy does not receive the influence of liquid level change.
The utility model density measurement float is with low cost, simple in structure, measurement range is big, measuring accuracy is high and precision do not receive liquid level change influence, can measure the advantages such as liquid level, density and quality of pot liquid simultaneously.
