Abstract
The invention provides a quantifying liquid-discharging structure with a middle exhaust pipe, which ensures the constant volume of discharging liquid each time, i.e. is capable of stably discharging liquid in a quantifying way. The quantifying liquid-discharging structure comprises a solution tank, a quantifying tank as well as a fluid-discharge pipe and an air inlet pipe below the quantifying tank. The quantifying liquid-discharging structure is characterized in that the bottom of the solution tank is communicated with the top of the quantifying tank below the solution tank through the two middle liquid pipelines, middle electromagnetic valves are respectively installed in the two middle liquid pipelines, the fluid-discharge pipe and the air inlet pipe are respectively installed at the bottom of the quantifying tank, lower electromagnetic valves are respectively installed in the fluid-discharge pipe and the air inlet pipe, one end of the middle exhaust pipe is communicated with one of the two middle liquid pipelines, the other end of the middle exhaust pipe is communicated with the upper part of the solution tank, the middle electromagnetic valves are opened and closed at the same time, the lower electromagnetic valves are opened and closed at the same time, and the middle electromagnetic valves and the lower electromagnetic valves are opened and closed at different times.
Description
Technical field
The present invention relates to quantitatively to descend the technical field of the structure of liquid, be specially the quantitatively lower liquid structure with intermediate exhaust pipe.
Background technology
In some chemical reaction, need interimly to provide for reactor the reaction liquid of given volume, but this relatively more difficult realization in practical operation; In addition, in the liquid process, conventional two-tube lower liquid method can not be discharged the gas in the bottom container under reaction liquid, and this can cause up and down and have pressure differential between container, namely can't stablize lower liquid.
Summary of the invention
For the problems referred to above, the invention provides the quantitatively lower liquid structure with intermediate exhaust pipe, it guarantees the constant volume of each lower liquid, can stably quantitatively descend liquid.
Quantitatively lower liquid structure with intermediate exhaust pipe, its technical scheme is such: it comprises NaOH solution tank NaOH, quantitative pot, quantitatively fill with discharging tube and the air inlet pipe of below, it is characterized in that: the bottom of described NaOH solution tank NaOH is by the top of the described quantitative filling of its below of two intermediate liquid pipeline communications, magnetic valve in the middle of two described intermediate liquid pipelines all are equipped with, the bottom of described quantitative filling is separately installed with described discharging tube, air inlet pipe, described discharging tube, air inlet pipe all is equipped with the bottom magnetic valve, one end of intermediate exhaust pipe is communicated with wherein of two described intermediate liquid pipelines, the other end is communicated with the top of described NaOH solution tank NaOH, magnetic valve all opens and closes simultaneously in the middle of described, described bottom magnetic valve all opens and closes simultaneously, described middle magnetic valve, the bottom magnetic valve is not opened simultaneously.
It is further characterized in that: an end of described intermediate exhaust pipe magnetic valve and describedly decide between the flow container in the middle of corresponding described of intermediate liquid pipeline.
After adopting structure of the present invention, when middle magnetic valve is opened simultaneously, the bottom magnetic valve all cuts out, liquid in the NaOH solution tank NaOH flows in the quantitative pot by deadweight, gas in the quantitative pot is discharged to the space on NaOH solution tank NaOH top by intermediate exhaust pipe, so just formed the loop between liquid and the gas, guarantee the stability of lower liquid, and make quantitative pot can be full of the liquid of certain volume; When the bottom magnetic valve is opened simultaneously, middle magnetic valve all cuts out, extraneous gas enters quantitative pot by air inlet pipe, the dependence deadweight in the quantitative pot discharges from discharging tube, it guarantees the constant volume of each lower liquid, can stably quantitatively descend liquid.
