Abstract
The utility model discloses a kind of liquid-transfering device, described liquid-transfering device comprises: liquid reserve tank, upper water check valve, floater controlled valve, pipette body, lower water check valve, graduation mark, screw connector and liquid injection port, there is liquid injection port on this liquid reserve tank top, liquid reserve tank and being tightly connected by screw connector with the pipette body of graduation mark, liquid reserve tank bottom and pipette body lower part are respectively equipped with water check valve and lower water check valve, and pipette body upper part is provided with floater controlled valve.The utility model advantage: control to move liquid process by upper and lower water check valve, a people can control multiple device simultaneously, by floater controlled valve automatic controlling liquid level height, improve and move liquid efficiency and precision, different size pipette body can be changed according to different situations simultaneously, reduce costs.
Description
Technical field
The utility model relates to a kind of chemical experiment measuring instrument, particularly relates to a kind of liquid-transfering device.
Background technology
At present, the pipette of experiment is all the glass tube of up/down perforation mostly, mouth of pipe imbitition is inserted by ear washing bulb during use, when the intraluminal fluid scale of construction is enough, remove ear washing bulb and block the glass mouth of pipe with finger, moveable finger or rotate glass tube and slowly reduce liquid level to the position needed, then move in the container that adds of needs.In this process, adopt the adjusted many liquid of mode of moveable finger or rotation glass tube, be difficult to control, sometimes need repeatedly to draw the uptake that repeatedly just can obtain needs, its process complexity is loaded down with trivial details, imbibition and the more difficult assurance of tapping operation, very easily occur inhaling many or put many after need the problem that repeats, higher to operator's technical requirement.In addition, during general experiment, some liquid drug (as distilled water etc.) can repeatedly be used, and laboratory technician frequently carries out the pipetting waste plenty of time.For overcoming above-mentioned technical deficiency, need the liquid-transfering device designing a kind of not only practicality and high efficiency but also can ensure to measure precision.
Utility model content
Content of the present utility model is to overcome the deficiencies in the prior art, provides a kind of simple to operate, liquid-transfering device that accuracy is high.
The utility model is achieved through the following technical solutions: a kind of liquid-transfering device, comprise liquid reserve tank, upper water check valve, floater controlled valve, pipette body, lower water check valve, graduation mark, screw connector and liquid injection port, this liquid reserve tank top is provided with liquid injection port, liquid reserve tank and being tightly connected by screw connector with the pipette body of graduation mark, liquid reserve tank bottom and pipette body lower part are respectively equipped with water check valve and lower water check valve, and pipette body upper part is provided with floater controlled valve.
As the preferred embodiment of technique scheme, this floater controlled valve is horn-like for being inverted, and bottom has graticule mesh to seal, and top and pipette body are tightly connected and leave pore.
As the preferred embodiment of technique scheme, the floating ball diameter in this floater controlled valve is between horn-like floater controlled valve 3 osculum and large mouth.
The utility model advantage: control to move liquid process by upper and lower, water check valve, a people can control multiple device simultaneously, by floater controlled valve automatic controlling liquid level height, improve and move liquid efficiency and precision, different size pipette body can be changed according to different situations simultaneously, reduce costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of floater controlled valve in the utility model.
Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
See Fig. 1, a kind of liquid-transfering device, comprise liquid reserve tank 1, upper water check valve 2, floater controlled valve 3, pipette body 4, lower water check valve 5, graduation mark 6, screw connector 7 and liquid injection port 8, this liquid reserve tank 1 top is provided with liquid injection port 8, liquid reserve tank 1 and being tightly connected by screw connector 7 with the pipette body 4 of graduation mark 6, liquid reserve tank 1 bottom and pipette body 4 bottom are respectively equipped with water check valve 2 and lower water check valve 5, and pipette body 4 top is provided with floater controlled valve 3.
Optimize, floater controlled valve 3 is horn-like for being inverted, and bottom has graticule mesh 32 to seal, and top and pipette body 4 are tightly connected and leave pore 31.
Optimize, ball float 33 diameter in floater controlled valve 3 is between horn-like floater controlled valve 3 osculum and large mouth.
Operation principle of the present utility model is as follows: need according to difference the pipette body 4 choosing different size, by screw connector 7, pipette body 4 is connected to liquid reserve tank 1.When needing to measure solution, close lower water check valve 5, open water check valve 2, solution in liquid reserve tank 1 can enter in pipette body 4, when liquid level rises to graticule mesh 32 and continues to rise, ball float 33 can rise with solution, and final ball float 33 rises to the top of floater controlled valve 3 and clogs outlet, due to atmospheric pressure effect, liquid level can stop rising, and just reaches the height of graduation mark 6.When needing to use solution, first close and close water check valve 2, then open lower water check valve 5, solution can export out from pipette, and the ball float 33 in floater controlled valve 3 is fallen in graticule mesh 32 again, moves liquid and terminates water check valve 5 under rear closedown and complete and move liquid process.The utility model controls to move liquid process by upper and lower, water check valve, a people can control multiple device simultaneously, by floater controlled valve automatic controlling liquid level height, improve and move liquid efficiency and precision, different size pipette body can be changed according to different situations simultaneously, reduce costs.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
