Description
Technical field
The present invention relates to a kind of liquid self-sealing sampling bottles.
Background technique
Currently, the requirement to atmosphere pollution, safety and environmental protection increases and sampling as oil refining, the industrialization of chemical industry increase
Pernicious gas enhances the injury of sample collector in the process, enclosed sampling system occurs, can obtain liquid under air-tight state
Sample.But some sampling bottles, using the method that gasket, pin hole are inserted into, its service life is short, loss is big, and there are the times
Difference, damage time are not fixed, and certain harm is brought to worker.
Summary of the invention
Goal of the invention: the purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of liquid self-sealing
Sampling bottle.
Technical solution: the technical scheme adopted by the invention is that a kind of such, liquid self-sealing sampling bottle, including bottle body
And bottle cap, the bottle cap are hollow chamber, the lower cavity wall of the chamber is connect with bottle sealing, the chamber side cavity wall
On be provided with gas outlet, be provided with hollow sealing bar in the chamber, the hollow sealing bar upper and lower end stretches out chamber
Outside, it stretches out on the outer hollow sealing bar upper end roof of chamber and is provided with inlet, stretch out on the outer hollow sealing bar bottom bar wall of chamber
It is provided with liquid outlet, along the multiple ventholes of hollow sealing bar circumference uniform distribution in lower cavity wall, stretches out under the outer hollow sealing bar of chamber
End end is connected with gasket, the gasket sealing for realizing inlet opening corresponding with outlet hole site, positioned at chamber
Sealing bar top is provided with upper limit platform, is provided with spring between the upper limit platform and lower cavity wall.
Preferably, the gas outlet is connected by conduit with adsorbent equipment.
Preferably, the bottle body bottom is arranged with scalding-prevention cover.
Preferably, the gasket uses rubber material or polyurethane material.
Preferably, the venthole is 2-5.
The utility model has the advantages that the present invention uses mechanical sealing, opened using the characteristic of spring with the insertion of sampling syringe needle
Sampling bottle inner sealing system, pulls out sampling bottle, bottle sealing system is restored to seal automatically, and zero leakage has been ensured and sampled
The injury of Cheng Zhongjie confrontation worker.
Detailed description of the invention
Structural schematic diagram when Fig. 1 is present invention sampling.
Fig. 2 is structural schematic diagram after present invention sampling.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
Referring to Fig. 1, a kind of liquid self-sealing sampling bottle, including bottle body 1 and bottle cap 2, the bottle cap 2 are hollow chamber
The lower cavity wall of room, the chamber is connect with bottle sealing, and gas outlet 3, the outlet are provided in the chamber side cavity wall
Mouth is connected by conduit with adsorbent equipment 4；It is provided with hollow sealing bar 6 in the chamber, on the hollow sealing bar 6,
Lower end is stretched out outside chamber, is stretched out on the outer hollow sealing bar upper end roof of chamber and is provided with inlet 7, stretches out hollow close outside chamber
It seals on bar bottom bar wall and is provided with liquid outlet 8, along the multiple ventholes 9 of hollow sealing bar circumference uniform distribution in lower cavity wall, it is preferable that
The venthole is 2-5, stretches out the outer hollow sealing bar lower end of chamber and is connected with gasket 10, the gasket 10 and
The corresponding sealing for realizing inlet opening in 9 position of venthole, is provided with upper limit platform 11 positioned at the sealing bar top of chamber, described
Spring 12 is provided between upper limit platform and lower cavity wall.
Preferably, the bottle body bottom is arranged with scalding-prevention cover (not illustrating in attached drawing).
Preferably, the gasket uses rubber material or polyurethane material.
When sampling, in sampling syringe needle insertion inlet, the liquid of acquisition enters in hollow sealing bar 6, in the liquid of acquisition
Under the action of weight power, hollow sealing bar 6 is moved down, and liquid outlet 8 is displaced downwardly in bottle body therewith, and the liquid of acquisition is by liquid outlet
8 go out to enter in bottle body, while gasket 10 leaves cavity wall under chamber, and the sealing of venthole 9 is automatically dismissed, the liquid institute of sampling
The gas of volatilization is entered in cavity by venthole, is gone out by gas outlet, is absorbed through adsorbent equipment, sampling is realized, when sampling terminates
Afterwards, the event resolves of the liquid gravity of acquisition, as shown in Fig. 2, compressed spring resets, hollow sealing bar 6 resets upwards, gasket
10 offset with cavity wall under chamber, and then realize the sealing of venthole 9 in cavity wall under chamber, to realize self-sealing, zero leakage is protected
The injury of sampling process intermediary confrontation worker is hindered.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
