摘要： A liquid-sampling structure located at the bottom of a vessel which contains the liquid from which samples are to be taken. A valve is located at the bottom end of the vessel and has a closed position closing the vessel and an open position providing a passage through which a sample of the liquid in the vessel can flow, a suitable supporting structure being located beneath the valve for supporting a test tube which receives the sample. A valve actuator is operatively connected with the valve to displace between its closed and open positions. A structure is operatively connected with the valve to form a fluid passage through which a cleaning fluid can be directed through the valve when it is in its closed position so as to clean the valve with a cleaning fluid while the valve is in its closed position. An additional fluid passage is provided for providing a path for a cleaning fluid in order to clean the interior of the structure which supports a test tube beneath the valve.
