[0002] In order to ensure the safe operation of the boiler and monitor the changes in the boiler water in real time, it is necessary to sample the boiler water regularly. The normal sampling interval is four to eight hours, and some precision boilers require sampling every two hours.

[0003] At present, the boiler water sampling process is carried out manually by holding a sampling bottle at the boiler water delivery pipe to take the sample. To ensure the representativeness of the sampling, the sampling valve is required to be opened before sampling, and the water is allowed to flow at a rate of 5L / min to 6L / min for 3 minutes before sampling. At the same time, the sampling bottle is washed 3-4 times with the sampled water before sampling. The temperature of boiler water is higher than that of ordinary boiling water due to high temperature and high pressure. Operators are easily scalded when washing the sampling bottle and taking samples, and the operation safety is low. Summary of the invention
