Abstract
The utility model discloses a quantitative sampling device for liquid. The device is characterized in that a liquid inlet end of a quantitative tube is connected with an interface of a three-way magnetic valve; the other two interfaces of the valve are respectively connected with a liquid storage bottle and an air pump; the liquid storage bottle is further connected with the other air pump; a liquid outlet end of the quantitative tube is connected with an interface of the other three-way magnetic valve; and other two interfaces of the valve are respectively connected with a liquid taking bottle and a liquid spilling bottle. The liquid storage bottle and the liquid spilling bottle are respectively closed and opened and respectively sit at the bottom and the top of the device. The quantitative sampling device is used for sampling for an automatic analytic instrument, and liquid in the liquid storage bottle can be forced into the liquid taking bottle in certain quantity under the control of the quantitative tube through the transformation by the air pumps and the magnetic valves, thereby realizing quantitative sampling. The device is simple and applicable and has accurate sampling, high reliability and favorable repeatability.
Description
Technical field
The utility model relates to a kind of liquid quantitative sampler that is used for the automated analysis instrument.
Background technology
The sampling of the liquid quantitative in the automated analysis instrument is at present adopted mostly by stepper motor and is added peristaltic pump that gearing forms as sampler, has three big shortcomings with the peristaltic pump sampling: the one, and the easy step-out of stepper motor and make to take a sample and forbidden; The 2nd, the yielding influence sampling of the pump line of peristaltic pump; The 3rd, pump head must compress pump line, tube wall is sticked together and can't take a sample.
The utility model content
The technical problems to be solved in the utility model is the weak point that overcomes existing peristaltic pump sampler, and a kind of simple and reliable, liquid quantitative sampler accurate, good reproducibility of taking a sample is provided.
The technical solution of the utility model is: the liquid quantitative sampler, mainly form by quantity tube, two three-way solenoid valves, two air pumps and liquid storage bottle, liquid taking bottle, discharge bottle, the liquid feeding end of described quantity tube links to each other with an interface of a solenoid valve, two other interface of this solenoid valve links to each other with an air pump with liquid storage bottle respectively, liquid storage bottle also links to each other with the another air pump, the outlet end of quantity tube links to each other with an interface of another solenoid valve, and two other interface of this solenoid valve links to each other with the discharge bottle with liquid taking bottle respectively.
Further scheme is: described liquid storage bottle inner chamber is airtight, and discharge bottle inner chamber opens wide; Described liquid storage bottle and discharge bottle place the minimum position and the high-order bit of this device respectively.
The utility model adopts existing suitable parts and corrosion resistant flexible pipe to assemble, and makes easily simple being suitable for.Earlier liquid is full of quantity tube during work by an air pump, by the another air pump liquid in the quantity tube all is pressed into liquid taking bottle again, getting liquid measure is controlled by quantity tube, accurately and reliably, but one or many is got liquid, good reproducibility can effectively overcome the defective of the inaccurate and poor reliability of the sampling of peristaltic pump sampling.
Description of drawings
Accompanying drawing is that the utility model is formed structural representation.
Embodiment
Further specify the composition structure of the present utility model and the course of work below by embodiment.
Referring to accompanying drawing, the liquid feeding end of quantity tube 4 links to each other with the interface a of three-way solenoid valve 3, two other interface b, the c of solenoid valve 3 links to each other with air pump 5 with liquid storage bottle 1 respectively, liquid storage bottle 1 also links to each other with air pump 2, the outlet end of quantity tube 4 links to each other with the interface d of three-way solenoid valve 7, two other interface e, the f of solenoid valve 7 links to each other with discharge bottle 8 with liquid taking bottle 6 respectively, and the ageing-resistant plastic cement pipe of corrosion resistant is adopted in each junction.Above-mentioned liquid storage bottle 1 inner chamber is airtight, and discharge bottle 8 inner chambers open wide, and liquid taking bottle 6 inner chambers also open wide.Liquid storage bottle 1 and discharge bottle 8 lay respectively at this and install minimum position and high-order bit.During work, open air pump 2 earlier and a of T-valve 3, b are communicated, liquid in the liquid storage bottle 1 is full of quantity tube 4, this moment, d, the f of T-valve 7 communicated, and unnecessary liquid enters discharge bottle 8, closes air pump 2 again, open air pump 5, a, the c of T-valve 3 are communicated, and d, the e of T-valve 7 communicate, and the liquid in the quantity tube 4 all is pressed into liquid taking bottle 6, finish primary sample, can in kind repeatedly take a sample, accurately control the liquid measure of getting in the liquid taking bottle, accurately, reliable, good reproducibility by quantity tube.After sampling is finished, the overflowing liquid in the discharge bottle 8 is flowed back in the liquid storage bottle 1 under action of gravity.
Claims (3)
1. liquid quantitative sampler, it is characterized in that mainly forming by quantity tube, two three-way solenoid valves, two air pumps and liquid storage bottle, liquid taking bottle, discharge bottle, the liquid feeding end of described quantity tube links to each other with an interface of a solenoid valve, two other interface of this solenoid valve links to each other with an air pump with liquid storage bottle respectively, liquid storage bottle also links to each other with the another air pump, the outlet end of quantity tube links to each other with an interface of another solenoid valve, and two other interface of this solenoid valve links to each other with the discharge bottle with liquid taking bottle respectively.
2. by the described liquid quantitative sampler of claim 1, it is characterized in that described liquid storage bottle inner chamber is airtight, discharge bottle inner chamber opens wide.
