Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
High-precision intelligent liquid level as shown in Figure 1 exports instrument, including linker 1, lead screw 2, drive system, control system,
Perfusion tube I 8, perfusion tube II 10, sealing container 9 and gas dynamic mode group, 1 upper end opening of linker connect with atmosphere, 1 bottom of linker
Side is connected to liquidometer 14, and lead screw 2 is arranged in linker 1, and 2 lower end of lead screw passes through linker 1 and is connected with drive system, is driven
Dynamic system is stepper motor or servo motor 3, and stepper motor or servo motor 3 are connect with lead screw 2 by shaft coupling 4, control system
System includes control panel 5, and control panel 5 connects controller 6, and controller 6 is connected with stepper motor or servo motor 3, perfusion tube I
8 one end is connected with sealing container 9, and sealing container 9 is provided with liquid medium 15, and one end of perfusion tube I 8 is located at sealing container 9
Bottom, that is, liquid level is hereinafter, the other end is connected with the feed screw nut 7 being arranged on lead screw 2, II 10 one end of perfusion tube and sealing container 9
It is connected, and is located at the liquid level of sealing container 9 or more, the other end is connected with gas dynamic mode group, and gas dynamic mode group includes gas source 12, vacuum hair
Raw device 13 and solenoid directional control valve 11, solenoid directional control valve 11 are 3-position-3-way solenoid directional control valve, one end of perfusion tube II 10 and electromagnetism
The oil outlet of reversal valve 11 connects, and gas source 12 is connect with an oil inlet of solenoid directional control valve 11, gas source 12 and solenoid directional control valve
