Abstract
The utility model discloses a liquid-chromatogram solvent bottle cover which has a simple structure, is convenient to assemble, is reliable to seal, does not influence the analyzing effect, is applicable to various volatile liquids, is provided with an outer cover (1) matched with the outside diameter of a bottle opening, and is characterized in that: an upper cover of the outer cover (1) is connected with an inner plug (2) matched with the inside diameter of the bottle opening, a hole (3) for closely inserting an infusion-pump pipeline is arranged on the inner plug (2), a through hole (4) is also arranged on the inner plug (2), and a pneumatic one-way valve (5) is placed in the through hole (4).
Description
Technical field:
The utility model relates to a kind of bottle cap that is used for the liquid chromatography solvents bottle, especially a kind of simple in structure, be convenient to assemble, seal reliably and not impact analysis effect, be applicable to the phase chromatography-use solvent bottle cap of various volatile liquids.
Background technology:
High-efficient liquid phase chromatogram technology is the high efficient separation technology that grew up in 20th century, has been widely used in fields such as Pharmaceutical Analysis, environmental monitoring, food security at present.Flowing phase from early stage mono-solvent relatively, has developed into organic solvents, particularly some deletrious, volatile organic solvents such as methyl alcohol, acetonitrile, chloroform as the indispensable important component part of liquid chromatogram (LC).Traditional solvent bottle only can be stored solvent, and bottle cap can not connect the entrance pipe of liquid chromatogram (LC) infusion pump.Infusion pipeline directly can only be inserted in the uncovered solvent bottle during installation, volatile organic solvent (flowing phase) will evaporate from bottleneck, and not only contaminated environment damages operating personal, but also the waste solvent.In recent years, along with the development of liquid chromatogram (LC) corollary equipment, famous consumptive material company of several in the world families has released brand-new solvent bottle, has promptly designed general-duty 1/8 on bottle cap " hydraulic pipe jointing; solved sealing problem to a certain extent, but but exist following contradiction.If seal the solvent bottleneck fully, though can thoroughly prevent the volatile liquid volatilization, can, cause the solvent cutout because of infusion pump suction is not enough, impact analysis effect greatly in case solvent output just causes a bottle interior negative pressure easily.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, provide a kind of simple in structure, be convenient to assemble, seal reliably and not impact analysis effect, be applicable to the phase chromatography-use solvent bottle cap of various volatile liquids.
Technical solution of the present utility model is: a kind of phase chromatography-use solvent bottle cap, the enclosing cover that is complementary with the bottleneck external diameter is arranged, be connected to the interior plug that is complementary with internal diameter of the bottleneck with the loam cake of enclosing cover, interior the tight patchhole of infusion pump pipeline arranged beyond the Great Wall, at the interior through hole that also is provided with beyond the Great Wall, through hole is built-in with the Pneumatic unidirectional valve.
Described Pneumatic unidirectional valve is provided with the housing screw that has centre hole, is with stage clip in the housing screw upper end, and the stage clip upper end joins with gas is stifled.
The upper end of plug is provided with and the inboard contacted packing ring of the loam cake of enclosing cover in described.
The lower end of plug is provided with outstanding seal ring in described.
The utility model is simple in structure, easy for installation, and set enclosing cover, interior plug, the tight patchhole of infusion pump pipeline and pneumatic stopping valve can guarantee convenience, safety storing solvent, can finish again with the chromatographic grade infusion pump to be connected; When bottle external pressure during greater than pressure of the inside of a bottle, air enters in the bottle by the Pneumatic unidirectional valve, avoid since in the bottle negative pressure cause the flowing phase cutout, guarantee analytical effect; When pressure of the inside of a bottle, starts check valve and ends during greater than the bottle external pressure because of solvent evaporates, guarantee sealing, prevent that solvent evaporates to bottle, can avoid the wasting phenomenon of hazardous solvent contaminated environment and solvent.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: have and solvent bottleneck outer-diameter threads bonded assembly enclosing cover 1, on enclosing cover 1, cover and be connected to the interior plug 2 that is complementary with internal diameter of the bottleneck, interior plug 2 can be made with polytetrafluoroethylene, the tight patchhole 3 of infusion pump pipeline is arranged on interior plug 2, be that the aperture is slightly less than the infusion pump pipeline, closely cooperate with assurance and infusion pump pipeline, also be provided with through hole 4 on interior plug 2, through hole 4 is built-in with the Pneumatic unidirectional valve 5 of ecto-entad.Pneumatic unidirectional valve 5 can outsourcing, but structure preferably shown in Figure 1, and is simple in structure, cost is low, promptly is provided with the housing screw 7 that has centre hole 6, is with stage clip 8 in housing screw 7 upper ends, and stage clip 8 upper ends and gas stifled 9 joins.For better sealing, be provided with and the inboard contacted packing ring 10 of the loam cake of enclosing cover 1 in the upper end of interior plug 2, the lower end of interior plug 2 is provided with outstanding seal ring 11.
During use, enclosing cover 1 spiral is connected outside the solvent bottleneck, 2 of interior plugs place in the bottleneck, and packing ring 10 contacts with the loam cake inner seal of enclosing cover 1, and seal ring 11 contacts with the bottleneck inner seal, and the infusion pump pipeline inserts from the tight patchhole 3 of infusion pump pipeline.When bottle external pressure during greater than pressure of the inside of a bottle, drive the stifled 9 inside micros of gas behind stage clip 8 pressurizeds, air then enters in the bottle along through hole 4, centre hole 6, avoid since in the bottle formation negative pressure cause flowing phase to stop.As pressure of the inside of a bottle because of solvent evaporates greater than the bottle external pressure, drive gas stifled 9 behind stage clip 8 pressurizeds and outwards stretch, stifled 9 of gas is blocked through hole 4, guarantees sealing, prevents that solvent evaporates is to bottle.
