Sampling device

Abstract

The utility model provides a sampling device, the sampling device is used for sampling a liquid sample in a sample pool, the sampling device comprises a drainage pipeline, a sampling assembly, a flushing pipeline and a control valve group, the drainage pipeline is used for communicating with the sample pool; the sampling assembly comprises a sampling pipeline and a sampling bottle, and the sampling pipeline can be communicated with the drainage pipeline, so that a liquid sample flows into the sampling bottle; the flushing pipeline is used for draining the flushing liquid, and the flushing pipeline can be communicated with the drainage pipeline, so that the flushing liquid flushes the sampling assembly; the control valve group has a sampling state and a flushing state, and the control valve group can be switched between the sampling state and the flushing state, so that the sampling pipeline is switched between communication with the drainage pipeline and communication with the flushing pipeline. The problem that in the prior art, a sampling device is low in efficiency is solved.
