Abstract
The utility model discloses a chemical reagent liquid extracting and mixing device. The device comprises a connecting plug connected with a bottleneck of a reagent bottle, wherein a liquid inlet pipe with a bottom arranged in the reagent bottle is arranged on the connecting plug; the top end of the liquid inlet pipe extends out of the top of the reagent bottle and is communicated with a liquid suction hole at the lower part of a three-way valve; an L-shaped liquid outlet pipe is communicated at a liquid outlet in one side of the three-way valve; a liquid storage cylinder with graduations is communicated at a liquid inlet at the top of the three-way valve via a pipeline; a piston is arranged in the liquid storage cylinder; a piston rod of the piston is connected with a press handle; a one-way air inlet valve is arranged on the connecting plug. The device has the advantages that the device has a simple structure, is convenient to use, measures the extracted and mixed liquid more accurately and conveniently and prevents smelly reagents from being volatilized into the air and harming human bodies in a liquid extraction process, thus improving the operating safety.
Description
Technical field
The utility model relates to chemical experimental instrument, especially relates to a kind of chemical reagent and gets liquid, liquid dispensing device.
Background technology
When at present people do experiment in laboratory, get liquid and the dosing process need be opened required reagent bottle usually, then the liquid in it is taken out.Get liquid and dosing process not only comparatively complicated, be difficult for taking out quantitative reagent, and reagent can evaporate in air due to the unlatching of reagent bottle, smell is comparatively unpleasant pungent, can certain harm be arranged to human body simultaneously.
Summary of the invention
The chemical reagent that the utility model purpose is to provide a kind of can seal, quantitative is joined reagent is got liquid, liquid dispensing device.
For achieving the above object, the utility model can be taked following technical proposals:
Chemical reagent described in the utility model is got liquid, liquid dispensing device, comprises the connection plug be connected with the reagent bottle bottleneck, is provided with bottom and is placed in the feed tube in reagent bottle on described connection plug; Described reagent bottle top is extended on described feed tube top, and be connected with the liquid sucting port of triple valve bottom, the liquid outlet connection of described triple valve one side is provided with L shaped drain pipe, and the inlet at described triple valve top is provided with and is with graduated liquid storage cylinder by pipeline communication; Be provided with piston in described liquid storage cylinder, the piston rod of described piston is connected with presses handle.
Be provided with breather cheek valve on described connection plug.
The utility model advantage is simple in structure, easy to use.Make that to get measuring of liquid and dosing more accurate, convenient; And get the liquid process and avoided being with reagent odorous to evaporate in air human body is damaged, improved the security of operation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, chemical reagent described in the utility model is got liquid, liquid dispensing device, comprises the connection plug 2 be connected with reagent bottle 1 bottleneck, is provided with bottom and is placed in the feed tube 3 in reagent bottle 1 on described connection plug 2; Described reagent bottle 1 top is extended on described feed tube 3 tops, and be connected with the liquid sucting port of triple valve 4 bottoms, the liquid outlet connection of described triple valve 4 one sides is provided with L shaped drain pipe 5, and the inlet at described triple valve 4 tops is communicated with to be provided with by pipeline 6 is with graduated liquid storage cylinder 7; Be provided with piston 8 in described liquid storage cylinder 7, the piston rod 9 of described piston 8 is connected with presses handle 10; Be provided with breather cheek valve 11 on described connection plug 2.
Its operation principle is: feed tube 3 is inserted in reagent bottle 1, and connection plug 2 is connected with bottleneck.In the time of need to getting liquid, extruding is pressed handle 10 reagent is drawn in liquid storage cylinder 7, when being evacuated to required scale, adjust triple valve 4, pipeline 6 is connected with L shaped drain pipe 5, the reagent inflow is got in liquid container and get final product, flow is accurate, easy and simple to handle, without opening bottle cap, can operate, avoided the volatilization of reagent; When needs during by other diluent liquid of the interior injection of reagent bottle 1, L shaped drain pipe 5 bottoms are inserted in liquid, on pull the liquid of pressing handle 10 suction aequums, triple valve 4 is adjusted to the state that pipeline 6 is connected with feed tube 3, liquid is injected in reagent bottle 1 and gets final product.
