Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a sampling bottle device. Background Art

[0002] Each thermal power plant and nuclear power plant needs to monitor the water vapor quality 24 hours a day, including online chemical analysis and manual sampling analysis. Among them, manual sampling analysis is a daily necessary operation item, which involves manual sampling devices. At present, most domestic sampling bottle devices are relatively simple, and there are many problems such as easy breakage, inconvenient operation, and inconvenient transportation during use.

[0003] The existing sampling bottle devices are of the following types:

[0004] 1. Open glass cup. This type of sampling device is easy to break and leak when transported to the laboratory. 2. Stainless steel sampling bottle. This type of sampling bottle has no exhaust. When the sample water enters the stainless steel sampling bottle, due to the difference in air pressure inside and outside, the sample water cannot flow smoothly into the sampling bottle, causing splashing. In daily operation, it is equivalent to an open glass cup, but the material is different.

[0005] The traditional sampling bottle device is affected by the glass material, resulting in low strength, easy breakage, and an unsmooth sampling process. At the same time, it is inconvenient to disassemble and assemble the pipeline before and after sampling, which affects the sampling efficiency. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling bottle device, comprising a stainless steel sampling bottle, the stainless steel sampling bottle is a sealed cylindrical can, one end of the stainless steel sampling bottle is equipped with a quick connector, the end of the stainless steel sampling bottle away from the quick connector is equipped with a needle valve, and the end of the stainless steel sampling bottle away from the needle valve is equipped with an exhaust valve.

[0008] Preferably, a handle is provided on the side of the stainless steel sampling bottle, and two sets of clamps are sleeved on the outer side of the stainless steel sampling bottle, and the handle is inserted into the inner side of the clamp.

[0009] Preferably, both ends of the stainless steel sampling bottle are connected with connecting pipes, the outer side of the connecting pipes is provided with threads, and the quick connector and the needle valve are respectively sleeved on the outer side of the connecting pipes and threadedly connected to the connecting pipes through the threads.

[0010] Preferably, a screw hole is provided at the end of the stainless steel sampling bottle, and one end of the exhaust valve passes through the screw hole, extends to the inner cavity of the stainless steel sampling bottle, and is threadedly connected to the screw hole.

[0011] Preferably, a limiting groove is provided on the outer side of the quick connector, and a sealing ring is embedded in the inner cavity of the limiting groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model can improve the strength of the sampling device through the stainless steel sampling bottle, and avoid the sampling bottle from bursting when sampling high-temperature sample water. At the same time, the stainless steel sampling bottle can be quickly connected to the sampling pipeline by using the quick connector. Since the quick connector and the sampling bottle are installed in a threaded connection manner, the size of the quick connector can be quickly changed according to the size of the sampling pipeline. Then, the exhaust valve can ensure the balance of the air pressure inside and outside the stainless steel sampling bottle when the quick connector is connected to the sampling pipeline, so that the sample water can quickly enter the stainless steel sampling bottle. At the same time, when the sample water is released, it also plays a role in balancing the air pressure inside and outside the stainless steel sampling bottle. The needle valve is used in combination with the exhaust valve to quickly discharge the sample water in the stainless steel sampling bottle. The structure is simple and easy to operate, and the sampling efficiency of the sampling bottle can be improved.
