Abstract
The utility model relates to a liquid sampling system which is characterized by comprising a sampling pipeline, a sampler and a time relay, a liquid inlet of the sampling pipeline is suitable for liquid to flow in, the sampler is arranged on the sampling pipeline, and a liquid inlet and a liquid outlet of the sampler are communicated with the sampling pipeline; the sampling pipeline is further provided with a first filter, a flow meter and a pump machine, and the first filter, the pump machine, the sampler and the flow meter are sequentially arranged in the flowing direction of liquid in the sampling pipeline; and the time relay is electrically connected with the control end of the sampler through the first safety barrier and the second safety barrier in sequence and is suitable for controlling the sampler to sample according to set time. The time relay has an accurate timing function, the action of the sampler can be controlled according to a preset time interval, the timing precision is high, the timing error of the time relay can be controlled at a millisecond level or even smaller in application, and the accuracy of sampling time can be ensured.
