Description

Sampling bottle

Technical Field

The utility model relates to the technical field of sample collection equipment, in particular to a sampling bottle.

Background

Because of the various environments near the spring and the groundwater wellhead, the hot spring water/gas and the groundwater/gas are very difficult in the collection process, especially, the sample is extremely easy to be polluted by air in the collection process, and the analysis result of rare gas isotopes is influenced.

At present, geologist's multi-purpose brine bottle or dual valve glass bottle gathers hot spring water/gas and groundwater/gas sample: the brine bottle is used for collecting the gas sample, a large funnel is used for collecting bubbles, and if no water poise exists around the spring eyes, the hot spring gas sample is almost impossible to collect; when a salt water bottle collects a water sample, if the water sample fills up the bottle body, the rubber plug can not plug the bottle mouth, so that air bubbles are always mixed in the collected water sample to influence the analysis result of rare gas; the double-valve glass bottle is suitable for collecting water samples, but the water pumping and pumping equipment is required to collect gas samples, repeated water drainage and pumping are required, and time and labor are consumed.

Disclosure of Invention

In order to solve the technical problems, the sampling bottle provided by the utility model can realize the collection of gas samples or water samples through natural gas and water separation in the hot spring water/gas and underground water/gas sample collection process, is time-saving and labor-saving, has two purposes, and can avoid the generation of air pollution.

The utility model provides a sampling bottle, comprising:

the top of the bottle body is provided with an opening;

the pipe body is fixedly arranged in the bottle body, the first port of the pipe body is positioned at the inner bottom of the bottle body, and the second port of the pipe body extends to the outside of the bottle body;

the first valve is arranged at the second port of the pipe body;

the second valve is arranged at the opening of the bottle body.

Preferably, the tube body is vertically arranged, and the upper end of the tube body and the opening of the bottle body are positioned on the same side.

Preferably, the first valve is arranged at a height lower than that of the second valve.

Preferably, both the bottle and the tube are made of transparent material.

Preferably, the method comprises the steps of, the first valve and the second valve are vacuum valves.

Compared with the prior art, the sampling bottle provided by the utility model has the beneficial effects that:

according to the utility model, through reasonable collocation of the inlet and the outlet of the sampling bottle, natural separation of gas and water in a sample is realized, so that the sampling bottle can selectively collect a gas sample or a water sample, the whole collection process is isolated from air, air pollution is avoided, the operation is simple, repeated water discharge and inflation are not needed, and time and labor are saved.

Detailed Description

Specific embodiments of the present utility model will be described in detail below with reference to fig. 1 to 3, but it should be understood that the scope of the present utility model is not limited by the specific embodiments.

As shown in fig. 1, the sampling bottle provided in this embodiment includes a bottle body 1, a tube body 2, a first valve 3, and a second valve 4, where an opening is provided at the top of the bottle body 1, and the second valve 4 is provided at the opening; the pipe body 2 is fixedly arranged in the bottle body 1, a first port of the pipe body is positioned at the inner bottom of the bottle body 1, a second port extends to the outside of the bottle body 1, and a first valve 3 is arranged at the second port.

In order to further avoid air pollution, the pipe body 2 is vertically arranged in the bottle body 1, the upper end of the pipe body 2 and the opening of the bottle body 1 are positioned on the same side, the first valve 3 is arranged at a height lower than that of the second valve 4, and the first valve 3 and the second valve 4 are high-vacuum glass valves.

To facilitate the observation of the amount of sample entered, both the bottle 1 and the tube 2 are made of transparent material.

Application method and principle

The utility model provides a sampling bottle, when collecting water sample, such asIn FIG. 2, the bottle 1 is placed in a normal position, spring water or groundwater is introduced into the inlet of the bottle 1 from the pipe 2, and V is opened _{Into (I)} A first valve 3 is arranged, the water sample enters the bottom of the bottle body 1, after the water sample rises to the ground surface from the ground, dissolved gas therein is desolventized to generate bubbles, and the gas can be converged at V _{Out of} Position, open V _{Out of} The second valve 4 at the position discharges the gas until the water sample is discharged from V _{Out of} After flowing out and keeping water flow flowing out for 5 minutes, the first valve 3 and the second valve 4 are closed, and water samples are collected for standby.

When collecting gas sample, as shown in FIG. 3, the bottle 1 is filled with spring water/groundwater, then the bottle 1 is turned upside down, and V is opened _{Into (I)} A first valve 3 for allowing spring water or groundwater containing bubbles to enter the bottle 1 from the inlet via the inlet pipe 2, and increasing the water pressure in the bottle 1 to open V _{Out of} And the second valve 4 is arranged, original spring water/underground water in the bottle body 1 is discharged through the second valve 4, gas in bubbles is gathered above the bottle body, and after enough gas is collected, the first valve 3 and the second valve 4 are closed to obtain a collected gas sample.

The foregoing disclosure is merely illustrative of preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto, and any variations within the scope of the present utility model will be apparent to those skilled in the art.
