Zusammenfassung:The utility model discloses an integrated closed sampling and feeding device and a high-pressure reaction kettle. The integrated closed sampling and feeding device comprises a tank body, a quick-opening seal head arranged at the top of the tank body, a connecting pipeline, an inflating pipeline, an emptying pipeline, a sampling pipeline and a pressure gauge, the connecting pipeline is connected with the high-pressure reaction kettle; one end of the tank body is provided with a gas phase interface, and the emptying pipeline and the inflating pipeline are both communicated with the gas phase interface; a sampling opening is formed in one end of the tank body; the sampling pipeline is communicated with the tank body through the sampling opening; and a pressure gauge port is formed in the quick-opening seal head and is communicated with a pressure gauge. According to the technical scheme, inert gas replacement is carried out through the gas filling pipeline before sampling so as to ensure that no air exists in th
