Abstract
The utility model discloses a negative pressure liquid sampling device. The technical problem that a sample is usually contaminated in the sampling process of the conventional liquid sampling device is solved. The negative pressure liquid sampling device comprises a liquid storage tank (2), a sampling bottle (5) and a vacuumized container (4). Liquid (1) is contained in the liquid storage tank (2). One end of a U-shaped sampling tube (3) is positioned below the liquid level of the liquid (1) in the liquid storage tank (2), and the other end of the U-shaped sampling tube (3) penetrates through the vacuumized container (4), and then is positioned in the sampling bottle (5). A sealing nut (6) is arranged at an inlet of the vacuumized container (4). An outlet of the vacuumized container (4) is in sealed connection with a bottleneck of the sampling bottle (5). An exhaust tube (7) is arranged on the sidewall of the vacuumized container (4). The negative pressure liquid sampling device has the effects of time saving and labor saving, and the consistency between a sample and an original is ensured.
Description
Technical field
The utility model relates to a kind of fluid sampling device, particularly a kind of device that utilizes negative pressure to carry out liquid sampling.
Background technology
The particle contamination analysis generally is that extract appearance begins from the work system device; For example to the analysis of power plant with oil; When extracting the sample of fluid; Usually can artificial pollutions such as dust, impurity, aqueous vapor be brought in the fluid sample of extraction, have influence on the accurate analysis of fluid sample and follow-up work subsequently.
Summary of the invention
The utility model provides a kind of liquid negative pressure sampling apparatus, has solved the normal contaminated technical matters of sample in sampling process that existing fluid sampling device exists.
The utility model overcomes the above problems through following scheme:
A kind of liquid negative pressure sampling apparatus; Comprise liquid reserve tank, sampling jar, vacuum-pumping container, in liquid reserve tank, be provided with liquid, an end of U-shaped liquid flowing tube is arranged on the liquid level below of the liquid in the liquid reserve tank; The other end of U-shaped liquid flowing tube is arranged in the sampling jar after passing vacuum-pumping container; The porch of vacuum-pumping container is provided with sealing nut, and the outlet of vacuum-pumping container and the bottleneck of sampling jar are tightly connected together, and the sidewall of vacuum-pumping container is provided with pump bowl.
Be arranged on the liquid level below 10-15 centimeters that hydraulic fluid port is positioned at liquid of getting of U-shaped liquid flowing tube in the liquid reserve tank.
The utlity model has save time, the labour-saving effect, guaranteed to be removed the consistance of sample and original.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
A kind of liquid negative pressure sampling apparatus; Comprise liquid reserve tank 2, sampling jar 5, vacuum-pumping container 4, in liquid reserve tank 2, be provided with liquid 1, an end of U-shaped liquid flowing tube 3 is arranged on the liquid level below of the liquid 1 in the liquid reserve tank 2; The other end of U-shaped liquid flowing tube 3 is arranged in the sampling jar 5 after passing vacuum-pumping container 4; The porch of vacuum-pumping container 4 is provided with sealing nut 6, and the bottleneck of the outlet of vacuum-pumping container 4 and sampling jar 5 is tightly connected together, and the sidewall of vacuum-pumping container 4 is provided with pump bowl 7.
The liquid taking port that is arranged on the U-shaped liquid flowing tube 3 in the liquid reserve tank 2 is positioned at the liquid level below 10-15 centimeters of liquid 1.
The utility model can be used for sampling occasions such as hydraulic pressure components and parts, hydraulic system, Hydraulic Station, transformer, Steam Turbine, engine, refrigeratory, well heater, oil pipe, pipe adapter, fuel tank, packoff.
Utilizing the utility model to carry out negative pressure, to get liquid appearance process following:
Step 2, lock the sealing nut 6 at the top of vacuum-pumping container 4 clockwise, make that liquid flowing tube is inner to form a kind of closed environment with sampling jar 5 is inner;
The sidewall of step 3, reciprocating sliding vacuum-pumping container 4 is provided with pump bowl 7, only needs back and forth for several times, is lower than the atmospheric pressure subenvironment because of the bottle chamber forms, and then liquid appearance is full of bottle very soon;
Above-mentioned sampling process, because of being that negative pressure is got liquid, and liquid flowing tube, liquid taking bottle do purified treatment in advance, and get in the liquid process, and liquid flowing tube, liquid taking bottle almost do not expose atmosphere, make airborne dust seldom sneak into liquid appearance, and liquid appearance contamination index is measured more near actual value.
Claims (2)
1. liquid negative pressure sampling apparatus; Comprise liquid reserve tank (2), sampling jar (5), vacuum-pumping container (4); In liquid reserve tank (2), be provided with liquid (1), it is characterized in that, an end of U-shaped liquid flowing tube (3) is arranged on the liquid level below of the liquid (1) in the liquid reserve tank (2); The other end of U-shaped liquid flowing tube (3) is arranged in the sampling jar (5) after passing vacuum-pumping container (4); The porch of vacuum-pumping container (4) is provided with sealing nut (6), and the bottleneck of the outlet of vacuum-pumping container (4) and sampling jar (5) is tightly connected together, and the sidewall of vacuum-pumping container (4) is provided with pump bowl (7).
2. a kind of liquid negative pressure sampling apparatus according to claim 1 is characterized in that, is arranged on the liquid level below 10-15 centimeters that hydraulic fluid port is positioned at liquid (1) of getting of U-shaped liquid flowing tube (3) in the liquid reserve tank (2).
