The invention discloses a sealed liquid sampler, relates to the industries of chemical production, pharmaceutical manufacturing and the like, and aims to extract samples in a reaction vessel when a user wants to determine whether a product is qualified or not by stirring and mixing in the reaction vessel during manufacturing of pharmaceuticals and chemical products. The air inlet of an air compressor is connected to an upper interface of an extraction bucket through an air compressor pipe; and a lower interface of the extraction bucket is connected to an extraction interface of the reaction kettle through an air compressor pipe. The air outlet of the air compressor is connected to the air inlet of the reaction kettle through an air compressor pipe, and meanwhile air in the extraction bucket is pumped out by the air compressor (negative pressure exists in the extraction bucket) and delivered into the reaction kettle (positive pressure exists in the reaction kettle), and liquid medicinein the reaction kettle fl
