Description
Technical field
The utility model relates to a kind of liquid metering device, belongs to the liquid measure technical field.
Background technology
In industrial and agricultural production and research work, often need implement the metering operation to liquid, need to select for use suitable gauging instrument could guarantee to measure the accurate of result at work.In the prior art, general liquid meter instrument exists that measuring accuracy is low, the shortcoming of bad adaptability, and the gauging instrument complex structure of senior precision, costs an arm and a leg, and is not suitable for using in common lab and daily monitoring.Chinese patent 01204162.9 discloses a kind of adjustable weir meter measuring device, and the cavity volume of this instrument can be adjusted, and measurement result can reach certain precision.But find that in real work this instrument also has certain shortcoming, should further improve as measuring accuracy; Hour there is bubble to be difficult for discharging in cavity volume, influences measurement accuracy; Can cause waste etc. during the excess liquid overflow.Therefore, above-mentioned gauging instrument being improved, is the problem of pendulum in face of scientific research personnel and technician.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of metering liquid volume precision height, rational in infrastructure, the corrosion resistant light-operated gauge line that is applicable to number of chemical reagent.
The technical scheme that solves the problems of the technologies described above is:
A kind of light-operated gauge line, it is made up of gauge line, two-bit triplet solenoid valve, photoelectric detection system, feed tube, discharging tube, feed tube and discharging tube are connected with the inlet and the leakage fluid dram of two-bit triplet solenoid valve respectively, the lower end of gauge line is connected with the indirect mouth of two-bit triplet solenoid valve, the upper end of gauge line is connected with the gas outlet of blower pump, and photoelectric detection system is installed on the excircle of middle and upper part of gauge line.
Above-mentioned light-operated gauge line, described photoelectric detection system are the grooved optocouplers.
The light-operated gauge line of this structure adopts the accurately volume of First Astronautic Research Institute for Measurement and Test's liquid that will detect of photoelectric detection system, measuring accuracy can reach 0.01mL, and has a good repeatability, metered volume can be finely tuned simultaneously, the utility model also has corrosion-resistant characteristic, measurable various chemical reagent.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: feed tube 1, two-bit triplet solenoid valve 2, discharging tube 3, gauge line 4, grooved optocoupler 5, blower pump 6
Embodiment
As seen from the figure, the utility model is made up of glass gauge line 4, two-bit triplet solenoid valve 2, grooved optocoupler 5.Inlet and leakage fluid dram place at two-bit triplet solenoid valve 2 are connected with feed tube 1 and discharging tube 3 respectively, the upper and lower end of gauge line 4 is connected with the gas outlet of blower pump 6 and the indirect mouth of two-bit triplet solenoid valve 2 respectively, and grooved optocoupler 5 is positioned on the excircle of middle and upper part of gauge line.Grooved optocoupler 5 models that an embodiment of the present utility model selects for use are MOC70T4.
In surveying work, its principle of work is: when metering liquid not, gauge line 4 communicates with discharging tube 3, and two-bit triplet solenoid valve 2 cuts out, and fluid to be measured is cut off.When the needs metering liquid, two-bit triplet solenoid valve 2 starts, and fluid to be measured can enter gauge line 4 by feed tube 1, the path blockade of gauge line 4 and discharging tube 3, measured liquid just slowly rises along gauge line 4, when liquid level arrived the position of grooved optocoupler 5, two-bit triplet solenoid valve 2 cut out automatically, and gauge line 4 is connected with the path of discharging tube 3, the liquid that is measured is discharged from discharging tube 3, after treating the liquid emptying, blower pump 6 starts, residual blowing out in will managing.In the utility model, the startup of two-bit triplet solenoid valve 2 and close and adopt relay control, the relay coil of relay J is connected with grooved optocoupler 5, the normally closed interlock of relay coil J is connected in the conducting loop of two-bit triplet solenoid valve 2, along with the conducting of grooved optocoupler 5 with end, the normally closed interlock of relay disconnects or is closed, makes two-bit triplet solenoid valve 2 close or start.This control circuit also has multiple design, all belongs to proven technique, repeats no more.
