Abstract
The utility model relates to a liquid preparation bottle for a liquid chromatograph, which is characterized by comprising a columnar bottle and a bottle plug capable of moving up and down, wherein the bottle plug is provided with a liquid inlet and a liquid outlet; by adopting the scheme, the gas can be prevented from being introduced into the liquid distribution bottle to pollute the liquid in the liquid distribution bottle to cause measurement errors.
Description
Technical Field
The utility model relates to a chromatograph field, concretely relates to liquid chromatograph is with joining in marriage liquid bottle.
background
A liquid dispensing bottle for a liquid chromatograph is characterized in that a bottle opening of a traditional liquid dispensing bottle for the liquid chromatograph is usually exposed in the air in the using process, so that the phenomenon that the liquid in the liquid dispensing bottle is polluted by the air easily occurs, and the detection accuracy is influenced. In view of this, the inventor of the present application has devised a liquid dispensing bottle capable of preventing the liquid in the liquid dispensing bottle from being contaminated.
SUMMERY OF THE UTILITY MODEL
For solving the above problem, the utility model discloses a following technical scheme realizes:
The liquid preparation bottle for the liquid chromatograph is characterized by comprising a columnar bottle and a bottle plug capable of moving up and down, wherein a liquid inlet and a liquid outlet are formed in the bottle plug, the liquid inlet is provided with a liquid inlet pipeline in a matching mode, a first check valve is arranged below the liquid inlet, a sealing cover is arranged above the liquid inlet, and the liquid outlet is provided with a liquid outlet pipeline in a matching mode.
Further, the bottle stopper is provided with an air hole, and a second check valve for preventing air from flowing inwards is arranged on the air hole.
Further, inlet lower extreme week is along being equipped with the mounting groove, check valve week edge be equipped with mounting groove assorted spliced pole, the spliced pole pass through the spring with mounting groove fixed connection, the inlet conduit lower extreme is equipped with a plurality of breachs.
further, the liquid inlet pipeline is connected with the liquid inlet through threads.
Furthermore, an elastic sealing plug is arranged between the liquid outlet pipeline and the liquid outlet.
furthermore, the upper end and the lower end of the sealing plug are provided with annular limiting blocks.
Has the advantages that:
Adopt this scheme, can not circulate to the bottle in using the air of pump suction sample in, the bottle completely isolates with the air and can not produce the pollution influence test result.

FIG. 2 is a schematic top view of the present invention;
Fig. 3 is a schematic view of the structure of the bottle stopper of the present invention.
The reference numbers are as follows:
1. A cylindrical bottle; 2. a bottle stopper; 21. mounting grooves; 22. a spring; 3. a liquid inlet; 31. a first check valve; 311. connecting columns; 32. a sealing cover; 33. a liquid inlet pipeline; 4. a liquid outlet; 41. a liquid outlet pipeline; 42. an elastic sealing plug; 421. a limiting block; 5. air holes; 51. a second check valve.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples, it being understood that the structure of the invention is not limited to the following examples:
As shown in fig. 1-3, a liquid dispensing bottle for a liquid chromatograph is characterized by comprising a cylindrical bottle 1 and a bottle stopper 2 capable of moving up and down, wherein the bottle stopper 2 is provided with a liquid inlet 3 and a liquid outlet 4, the liquid inlet 3 is provided with a liquid inlet pipeline 33, a first check valve 31 is arranged below the liquid inlet 3, a sealing cover 32 is arranged above the liquid inlet 3, and the liquid outlet 4 is provided with a liquid outlet pipeline 41. When the liquid dispensing bottle is tested, the liquid in the liquid dispensing bottle is reduced by pumping the liquid through the high-pressure pump, negative pressure is formed in the bottle, and the movable bottle stopper 2 moves downwards to replace inward circulation of air, so that the liquid in the liquid dispensing bottle is completely isolated from the air.
Further, the bottle stopper 2 is provided with an air hole 5, and a second check valve 51 for preventing the air from flowing inward is disposed on the air hole 5. The air hole 5 is provided for exhausting the liquid preparation bottle, nitrogen is firstly introduced into the bottle through the liquid inlet 3 before liquid is filled in, the gas is discharged from the air hole 5, the internal gas is ventilated, and then the liquid is introduced. The second check valve 51 prevents the gas from sucking back the contaminated liquid
Further, 3 lower extreme week edges of inlet are equipped with mounting groove 21, check valve week edges be equipped with 21 assorted spliced pole 311 of mounting groove, spliced pole 311 pass through spring 22 with 21 fixed connection of mounting groove, the 33 lower extremes of inlet conduit is equipped with a plurality of breachs. Adopt this scheme, in letting in liquid the time back-open check valve through inlet channel 33, liquid flows into in the bottle from the breach of below.
Further, the liquid inlet pipe 33 is connected with the liquid inlet 3 through a thread. The screw connection can achieve a complete sealing effect, and the sealing cover 32 can also be sealed in a threaded manner.
Further, an elastic sealing plug 42 is arranged between the liquid outlet pipe 41 and the liquid outlet 4. The elastic sealing ring can achieve good air tightness.
Further, the upper and lower ends of the sealing plug are provided with an annular limiting block 421. The limiting block 421 can fix the elastic sealing ring, i.e. fix the liquid outlet pipe 41, and only needs to ensure that the liquid outlet pipe 41 touches the liquid.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
