Abstract
A micro-scale meter for measuring standard volume is composed of a measuring box 1, absorbent powder 2, a measuring cup 3, a measuring tube 4, an aqueous solution 7 and a measuring ruler 9. It features that the lower part of the measuring box 1 has a layer of water-absorbing powder 2, the measuring tube 4 is a glass product with one thick end and one thin end, and the liquid used by the measuring device is aqueous solution, so that it can not be poisoned by working personnel when measuring standard volume, and the measured volume of the measured device is accurate, and its measuring speed is quick, and the whole measuring process is simple and convenient to operate, so that it is an ideal micro-scale meter.
Description
The measurement standard volume is all used liquid mercury both at home and abroad at present, because the volatilization of mercury enters human body by respiratory tract, scientific research shows that air-borne mercury concentration is higher than 0.25mg/M
3Just have 56.7% staff to poison, the annual whole nation has the tens of thousands of people to poison, and is very harmful to the person, is built in this has developed a kind of measurement standard volume because of the inventor microflowmeter measuring device.
The purpose of this utility model is to design does not a kind ofly poison when the measurement standard volume, and to make metering liquid phase biconditional operation convenient and simple with mercury in metering speed and accurately, replaces the microflowmeter measuring device of mercury measurement standard volume with aqueous solution.
The utility model is achieved in that metering box made of plastic, profile is a rectangle or square, in the metering box a plurality of circular troughs are arranged, trench bottom promptly measures the box bottom one deck absorbing water powder, this absorbing water powder can blot gauge line and tested measurement instrument, jigger is housed in the circular trough, this jigger can be plastics or glassware, dress metering aqueous solution or measurement instrument in the jigger, gauge line is the device that splashes into aqueous solution in tested measurement instrument, and it is a glassware, one pluckings one thin, thick head end is equipped with rubber capsule, adorn a resistance piece in the gauge line, pipe is marked with scale, and the time spent can not place on the metering box when gauge line, also need a measuring stick when the measurement standard volume, measuring stick can be plastic products.
The utility model compared with prior art its maximum characteristics is: eliminated the mercury operation when the measurement standard volume, the staff can not poison, it is avirulence, next is each absorbing water powder of aqueous solution by special liquid and powder so that tested utensil is surveyed volume is accurate, and the fast whole measuring process of metering speed is easy to operate simply.
Be elaborated below in conjunction with accompanying drawing:
Fig. 1 is the front view of microflowmeter measuring device
Fig. 2 is the vertical view of microflowmeter measuring device
Fig. 3 is the side view of microflowmeter measuring device
1 is the metering box among the figure, its profile is rectangular, in the metering box 6 circular troughs are arranged, one deck absorbing water powder 2 is arranged at the bottom of metering box, and a jigger 3 is all arranged in each circular trough, can put into aqueous solution 7 or measurement instrument 8 in the jigger 3, it is glassware for a gauge line 4, one pluckings one thin, thick head end is equipped with rubber pocket 6, adorn a resistance piece 5 in the pipe, pipe is marked with scale, and measuring stick 9 is the plastic products of a standard, when measuring a standard volume, at first tested utensil is put into jigger 3, take out institute's survey utensil then, the aqueous solution 7 in the gauge line 4 splashes into tested utensil, measure liquid height with measuring stick 9 at last, promptly draw the volume of tested utensil.
Claims (4)
1, a kind of microflowmeter measuring device of measurement standard volume, it is made of in the metering box 1 metering box 1, jigger 3, gauge line 4, aqueous solution 7 and measuring stick 9 a plurality of circular troughs, adorn a jigger 3 in the groove, can put into aqueous solution 7 or measurement instrument 8 in the jigger 3, it is characterized in that one deck absorbing water powder 2 is arranged at the bottom of measuring box, gauge line 4 is a glassware, it one pluckings one thin, thick head end is equipped with rubber capsule 6.
