Description
Technical Field

[0002] A sampler is a sampling device used for heat exchange of steam and water tests and samplings in boiler rooms or power plants, that is, for heat exchange of media such as liquids and gases with relatively high temperatures. Most of the water in boilers and thermal systems has relatively high temperatures, and high water temperatures are not convenient for sampling and determination of tests. Therefore, cooling should be carried out during sampling, that is, the sample at the sampling point is introduced into a sampling cooler for cooling. Generally, it is required to ensure that when the flow rate is 500 - 700 mL / min, the sample can be cooled to below 30 - 40 degrees, meeting the standard of DL / T 457-91 in the electric power industry of the People's Republic of China.
[0003] However, when the existing sampler is used for downhole sampling, due to the uneven downhole ground, it is rather troublesome for the drill bit to reach the ground for sampling during sampling. Moreover, due to the unclear downhole conditions, it is very easy to encounter stones and other situations during sampling. However, when some samplers encounter stones during sampling, it is very easy to cause damage to the sampler, resulting in certain losses.
