Detailed description of the invention
Fig. 1 is the structure chart that a kind of high-precision of the utility model takes liquid case.
Specific embodiment
As shown in fig.1, a kind of high-precision takes liquid case, including cabinet 1, liquid storage chamber 2, liquid outlet 3, piston 4, small-sized pneumatics
Machine 5, water inlet 6, solenoid valve 7, button 8 and controller 9, the liquid storage chamber 2 are set in cabinet 1, and the liquid outlet 3 is set to cabinet
1 lower end is connect with liquid storage chamber 2；The piston 4 is set in liquid storage chamber 2, and liquid storage chamber 2 is divided into two chambers；The small size air
Press 5 is set to 1 top of cabinet, is connected to by tracheae with the top of liquid storage chamber 2, and the top of the liquid storage chamber 2 is equipped with pressure regulator valve 21；
The water inlet 6 is connect with the lower part of liquid storage chamber 2, and the solenoid valve 7 is set to liquid outlet 3 and water inlet, the button 8 and electricity
Magnet valve 7 connects；The controller 9 is set on cabinet 1, and the small-sized air compressor 5, solenoid valve 7 and pressure regulator valve 21 and controller 9 connect
It connects.
The top of the liquid storage chamber 2 is equipped with pressure release electromagnetic valve 22, and the pressure release electromagnetic valve 22 is connect with controller 9.
The controller 9 is single-chip microcontroller, and single-chip microcontroller realizes that water yield is gentle by controlling the opening time of each solenoid valve
The control of pressure.
The liquid outlet 3 is equipped with button 8, is labeled with single liquid-taken amount on button 8, liquid-taken amount be equipped with 1ml, 2ml, 5ml,
10ml、50ml。
1 surface of cabinet is equipped with start button 11.
In use, connecting power supply, water inlet is connect with distilled water outlet pipe, sets upper piston area by pressure regulator valve
Air pressure.Pipeline and power supply are connected, started by press button, the solenoid valve of single-chip microcontroller control water inlet is opened to be infused into liquid storage chamber
Water, pressure release electromagnetic valve are opened, piston upwards, are injected a certain amount of or are closed each solenoid valve after filling water.Experimentation takes liquid
When, the button for needing to measure amount of liquid is pressed, as can not be disposably obtained, can repeatedly be added measurement, by lower button, is accordingly gone out
The solenoid valve of liquid mouth is opened the corresponding time, and water inlet solenoid valve opens fluid infusion, and according to the pressure value that pressure regulator valve is set, pressure is excessive
