Abstract
The utility model discloses a liquid volume controlling device which comprises a container and a container cover mated therewith for use. The container cover is provided with a first guide tube and a third guide tube in a penetrating manner, wherein the third guide tube is connected with a first gas pressure adjusting mechanism. After the first guide tube and a first storage container are connected and when negative pressure is output by the first gas pressure adjusting mechanism, a sample solution flows from the first storage container to the container along the first guide tube, and then the inserting depth of the first guide tube is adjusted and the first gas pressure adjusting mechanism is adjusted for inputting positive pressure. Therefore, the superfluous sample solution above the inserting end of the first guide tube can be pressed back to the first storage container, such that the volume of liquid that flows into the container is accurately controlled.

Summary of the invention
The utility model technical matters to be solved is, a kind of convenient and practical, a kind of liquid volume control device that accuracy is high is provided.
For solving above technical matters, the technical scheme of the utility model is: a kind of liquid volume control device, comprise container and the container cover that is used with said container, and run through on the said container cover that first mozzle and the 3rd mozzle being installed.Wherein, said the 3rd mozzle is connected with the first gaseous tension governor motion.
As the improvement of the utility model, run through also on the said container cover that second mozzle being installed.
Wherein, said second mozzle communicates with second storage container, and said second storage container connects with the second gaseous tension governor motion.
Preferred embodiment as the utility model: said second mozzle communicates with said second storage container through the second switch valve, and said second switch valve is a T-valve; The inlet end of said T-valve (21) is connected with said second mozzle, and first endpiece (23) of said T-valve is connected with pump, and second endpiece (22) of said T-valve is connected with second storage container.
Wherein, said first and second gaseous tension governor motion (10,12) is blower fan.
Preferential embodiment as the utility model: on said first mozzle first controlled valve is installed; Said first mozzle is connected with first storage container, said first mozzle, and with first storage container, the input end of the connecting pipe that is connected is provided with filtration unit.
Through implement the utility model desirable following beneficial technical effects: container cover and container are used; Run through on the container cover first mozzle, second mozzle and the 3rd mozzle are installed; First controlled valve is installed on first mozzle; The second switch valve is installed on second mozzle, and the insertion depth of first mozzle and/or second mozzle can be regulated, and the 3rd mozzle is connected with the gas pressure regulating device.Be connected with first storage container at first mozzle, during second switch valve closing and gaseous tension governor motion output negative pressure; Sample solution will enter in the container along first mozzle from first storage container; Insertion depth and the adjustment gaseous tension governor motion of adjusting first mozzle this moment make its input malleation, reach the purpose that accurate control flow into the liquid volume in the container thereby so just can push back the unnecessary sample solution more than the first mozzle insertion end first storage container; When second mozzle and pump connection; Can in container, add sample solution through pump; After question response was accomplished, the path of closing second mozzle and pump was also opened the path of second mozzle and second storage container simultaneously, and regulating the second mozzle insertion depth and making second storage container interior is negative pressure state; So just can let the above liquid of the second mozzle insertion end flow in second storage container, promptly can accurately control the volume of this part liquid.
Obviously, the utility model can accurately be controlled the liquid volume that joins in the container efficiently and the volume of the liquid that takes out in the container through implementing.
Description of drawings
Below in conjunction with Figure of description the utility model is done further detailed explanation, wherein:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model duty one synoptic diagram;
Fig. 3 is the utility model duty two synoptic diagram.
Embodiment
As shown in Figure 1, a kind of liquid volume control device comprises container 6 and the container cover 3 that is used with said container 6, runs through on the said container cover 3 that first, second and third mozzle 7,8,9 being installed.Said the 3rd mozzle 9 is connected with the first gaseous tension governor motion 10.Said second mozzle 8 communicates with second storage container 11, and said second storage container 11 connects with the second gaseous tension governor motion 12.Wherein, Said second mozzle 8 communicates with said second storage container 11 through second switch valve 2; Said second switch valve 2 is a T-valve; The inlet end 21 of said T-valve is connected with said second mozzle 8, and first endpiece 23 of said T-valve is connected with pump 1, and second endpiece 22 of said T-valve is connected with second storage container 11.
Wherein, said first and second gaseous tension governor motion 10,12 is blower fan.In addition, on said first mozzle 7 first controlled valve 4 is installed, said first mozzle 7 is connected with first storage container 5.
As shown in Figure 2, be that extraction container vacuumizes through the first gaseous tension governor motion, 10 blower fans with container 6, second switch valve 2 is closed, and fluid sample gets into container 6.Treat that liquid level reach a certain height when as shown in Figure 2; Through the first gaseous tension governor motion, 10 blower fans container 6 is pressurizeed; Part liquid is discharged from container 6 and turns back in first storage container 5, when treating that liquid level reaches state as shown in Figure 3, because the influence of the tension force of liquid; Liquid level behind the constant volume can be lower than first mozzle 7 slightly, can reach the purpose of accurate constant volume different volumes through the length of adjusting first mozzle 7.During extraction through regulate second switch valve 2 utilize can accurate measurement micro pump 1 inject organic solvents to aequum to container 6.After extraction finishes, on WS upper strata, can vacuumize second storage container 11, the organic solvent in the container 6 is fetched in second storage container 11, can carry out post-treatment operations through the second gaseous tension governor motion, 12 blower fans for organic solvent layer.
