Abstract
The utility model relates to a sampling device for chemical analysis, in particular to a sealed sampling device which comprises a sampling bottle and a bottle cap capable of sealing the mouth of the sampling bottle. The sampling device is characterized in that a sampling tube and an exhaust tube are respectively mounted on the bottle cap; the outer walls of the two tubes are hermetically connected with the bottle cap and communicated with the inner part of the sampling bottle; a three-way valve is mounted on the sampling tube; and an exhaust valve is mounted on the exhaust tube. The utility model adopting the technical scheme has the following characteristics: firstly, the influence of a sampling environment on the sampling is basically avoided, and particularly, the sampling device is suitable for provinces in the west where sand blowing frequently occurs and four seasons are distinct; secondly, the intermediate link and the manual operation are reduced, the influence on the sampling caused by human actions is avoided, and the use is convenient; and thirdly, the technology of detecting the granularity of insulating oil reaches to higher test levels.
Description
Affiliated technical field
The utility model relates to the sampler in the chemical analysis, particularly seals sampler.
Background technology
The authenticity of sample is the prerequisite of chemical analysis accuracy.At present power industry to oil system in the electric equipment of transformer ' s type and steam turbine, the hydraulic turbine and oil tank in the granularity testing process of insulating oil, lubricating oil, sampling process is fairly simple, be with above-mentioned oils without any the protection situation under, put into sampling jar, the sample of being got will be subjected to surrounding environment and get air, dust pollution like this, thereby has influence on the accuracy of detection.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of not affected by environment, sealing sampler that can truly reflect the sample situation is provided.
For achieving the above object, the technical solution of the utility model is: a kind of sealing sampler, comprise sampling jar and the bottle cap that the sampling bottleneck can be sealed, it is characterized in that on bottle cap, being separately installed with stopple coupon and gas outlet, the outer wall of above-mentioned two pipes is connected with bottle cap is airtight, and communicate in the two pipe sampling jars, T-valve is installed on stopple coupon, vent valve is installed on gas outlet.
On above-mentioned bottle cap, pressure-indication means is installed.
Technical solutions of the utility model have following characteristics: 1, avoided the influence of sampling environment to sampling substantially, particularly many at western strong wind dust and sand weather, the province that makes a clear distinction between the four seasons is especially suitable; 2, reduced intermediate link and manual operations, avoided artificially influence taking a sample, easy to use; 3, the granularity detection technique of insulating oil has been mentioned a higher test level.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, this sampling jar be made up of sampling jar 8 and the bottle cap 1 that the sampling bottleneck can be sealed, on bottle cap, be separately installed with stopple coupon 4 and gas outlet 5 with the sampling jar intracavity inter-connection, T-valve 2 is installed on stopple coupon, vent valve 6 is installed on gas outlet.Before using sampling jar is cleaned, after the oven dry, the bottle cap of will taking a sample covers completely, simultaneously with T-valve, exhaust valve closure, makes to be in air-tight state in the sampling jar.During sampling, now with the stopple coupon on sampled equipment oil system or the oil tank with after stopple coupon 4 on the sampling jar is connected, T-valve is opened to the position that the stopple coupon on equipment oil system or the oil tank communicates with bypass 3 on the T-valve, liquid in the sampled equipment can not enter in the sampling jar at this moment, discharge by bypass 3, by the liquid of emitting earlier the stopple coupon on the sampled equipment is cleaned up like this, and then the open site of change T-valve, the liquid that flows out in the stopple coupon on the sampled equipment is flowed in the sampling jar, open vent valve 6 simultaneously.The pressure-indication means of installing on the bottle cap 7 is to use when cleaning sampling jar, is used to show the pressure in the sampling jar.
Claims (2)
1. sealing sampler, comprise sampling jar and the bottle cap that the sampling bottleneck can be sealed, it is characterized in that on bottle cap (1), being separately installed with stopple coupon (4) and gas outlet (5), the outer wall of above-mentioned two pipes is connected with bottle cap is airtight, and communicate in the two pipe sampling jars (8), T-valve (2) is installed on stopple coupon (4), vent valve (6) is installed on gas outlet (5).
2. sealing sampler according to claim 1 is characterized in that being equipped with pressure-indication means (7) on above-mentioned bottle cap (1).
