Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of chemical reagent charger of the present invention, as shown in figure 1, including the liquid bottle 2 on platform balance 1, the bottleneck of liquid bottle 2
It is embedded to be cased with being matched therewith rubber stopper 3, glass tube 4 is provided with rubber stopper 3, the one end of glass tube 4 extends inside feed liquor bottle 2,
The other end of glass tube 4 connects needle tubing 5, has on needle tubing 5 and promotion plug 6 is provided with volume markings, needle tubing 5, and 2 bottle mouth positions of liquid bottle are also
Lid 7 is coated with, plug unit is provided with lid 7；When needing with weight as unit adding liquid, carried out using platform balance 1
Metering；When it is unit adding liquid to need to use volume, measured using needle tubing 5.
The one end of lid 7 is connected through a screw thread with the bottleneck outer wall of liquid bottle 2, and fixed lid 7 and liquid bottle 2 are difficult to separate；Stopper 7
The other end set through hole 8, and through hole 8 pass through rubber stopper 3.
As shown in Fig. 2 plug unit includes the rotating piston 9 being threadedly coupled with through hole 8, the one end of rotating piston 9 connects handle 10,
The other end of rotating piston 9 is uniformly distributed circumferentially some supporting plates 11, and spring 12 is passed through between the adjacent supporting plate 11 of each two
Connection, spring 12 in through hole 8 is in compressive state, and when through hole 8 is passed, spring 12 is opened, supporting plate 11 and rubber stopper 3
Bottom connection is touched, and by rotary handle 10, extracts rubber stopper 3.
Vacuum valve 13 is provided with liquid bottle 2, liquid-resistant valve 14 is provided with glass tube 4.
Platform balance 1 is sequentially connected vacuum valve 13 by wire 15 and liquid-resistant valve 14 forms closed-loop path.
The course of work of charger of the invention：
