Abstract
The utility model discloses a constant volume liquor filling device with a volumetric flask, comprising a supporting bracket with a base plate, a post; a clip ring with a bayonet with sliding cooperation with the post and a shelf for volumetric flask and a container. Such bayonet and the volumetric flask are fixed with the post respectively with help of the screws on the post head. A T-pipe rests under the container, and a piping is laid in the bayonet, the two liquor outlet pipings are set with pistons with radial through opening respectively, the outlet aperture of such two liquor outlet piping are different, and the adjustment of radial through hole location of the piston is able to control the liquor in the container to flow into the volumetric flask with bulky flow or tiny flow. Such structure of constant volume liquor filling device with a volumetric flask is simple and convenient to enhance work efficiency of operators for accuracy of the constant volume. The utility model cuts down error of the constant volume and waste of samples, especially for large number of volumetric flask in need of constant volume, getting rid of failure constant volume due to fatigue and carelessness in the traditional constant volume method.
Description
Technical field
The utility model relates to a kind of volumetric flask constant volume liquid-adding device.
Background technology
At present, the constant volume of volumetric flask all is earlier solution to be added to nearly volumetric flask graduation mark, and hand-held then volumetric flask keeps volumetric flask graduation mark and eyes on same plane, uses dropper or suction pipe liquid feeding again instead to scale.Shortcoming with this method constant volume is: keep volumetric flask graduation mark and eyes on same plane with " hand ", under the situation of constant volume continuously in enormous quantities, because tired or paralysis usually can cause and look up or overlook constant volume, cause the constant volume failure; In addition, to scale, often owing to dropper or suction pipe characteristic are held inaccurate, very easily liquid feeding surpasses scale, can cause the constant volume failure equally with dropper or suction pipe liquid feeding.
Summary of the invention
The purpose of this utility model provides a kind of volumetric flask constant volume liquid-adding device, to simplify the operation, improves the accuracy of work efficiency and raising volumetric flask constant volume.
The technical scheme that its technical problem that solves the utility model adopts is: volumetric flask constant volume liquid-adding device comprises by base plate, the bracing frame that vertical rod constitutes, the snap ring with bayonet and volumetric flask shelf and the container that are slidingly matched with vertical rod, snap ring and volumetric flask shelf are fixed by injection head screw and vertical rod respectively, there is three-way pipe the below of container, one of them pipeline places snap ring, be respectively arranged with the first piston and second piston on two fluid pipelines in addition, the outlet aperture of these two fluid pipelines is inequality, and the first piston and second piston have radial direction through hole respectively.
During use, volumetric flask is placed on the shelf and adjusts the volumetric flask position, and its eyes and volumetric flask graduation mark were on same plane when the experimenter was seated.Adjust the position of snap ring in vertical rod, make two fluid mouths of pipe be positioned at the top of volumetric flask, by regulating piston radial direction through hole position, the solution that can control in the container flows into volumetric flask with thick stream or thread mode, beginning uses during liquid feeding thick stream can improve the speed of constant volume, the degree of accuracy of using thread can improve constant volume when near the volumetric flask graduation mark.
The beneficial effects of the utility model are: volumetric flask constant volume liquid-adding device is simple in structure, and is easy to use, can effectively improve experimenter's operating efficiency, improves the accuracy of constant volume, reduces the waste of constant volume sum of errors to sample.Especially need under the situation of constant volume at volumetric flask in enormous quantities, overcome traditional constant volume method because drawback tired or that paralysis easily causes constant volume to fail.
Description of drawings
Fig. 1 is a volumetric flask constant volume liquid-adding device schematic diagram;
The specific embodiment
With reference to Fig. 1, volumetric flask constant volume liquid-adding device comprises by base plate 1, the bracing frame that vertical rod 3 constitutes, snap ring 4 with bayonet, volumetric flask shelf 5 and container 8, the installing handle of snap ring 4 and volumetric flask shelf 5 is enclosed within respectively in the vertical rod 3, be with vertical rod 3 and be slidingly matched, and fixing by injection head screw 2 respectively with vertical rod 3.Snap ring 4 is positioned at the top of volumetric flask shelf 5, there is three-way pipe the below of container 8, one of them pipeline places snap ring 4 through bayonet socket, be used to make container to be installed in bracing frame, be respectively arranged with the first piston 7 and second piston 9 on two fluid pipelines in addition, the outlet aperture of these two fluid pipelines is inequality, forming one is thick flow export 6, another is thread outlet 10, and the first piston 7 and second piston 9 have radial direction through hole respectively, and rotary-piston can be controlled liquid stream and open and close, when the radial direction through hole of piston communicates with pipeline, liquid is smooth logical, otherwise, for closing.
