Abstract
A sample tube of a sampling valve is moved up and down by a cylinder. When the sample tube is moved downward, a sample inlet opposes a stored sample, and the sample can be extracted. When the sample tube is moved upward, the sample inlet opposes a cleaning liquid path. Thus, cleaning liquid is fed into the cleaning liquid path from a cleaning liquid supply port of a cleaning pipe. The cleaning liquid flows within the sample tube from the sample inlet, and flows out from a sample discharge port. Thus, an entire interior of the sample tube can be cleaned. In a sample extracting device using the sampling valve, a state in which no air or impurities are mixed in the sample can always be maintained, such that stable extraction can be carried out.
