Closed liquid ammonia sampling protector

The utility model relates to the technical field of liquid ammonia sampling devices, in particular to a closed liquid ammonia sampling protector which comprises a transparent sealing box, an upper layer plate and a lower layer plate, an upper top plate and a lower bottom plate which are movable in a drawing mode are arranged on the top and the lower portion of the sealing box respectively, and the upper layer plate and the lower layer plate are fixedly arranged in the sealing box from top to bottom at intervals. A plurality of first clamping holes and second clamping holes are respectively formed in the upper-layer plate and the lower-layer plate. The sealing box is made of a transparent material, so that a worker can observe the liquid level condition of liquid ammonia in real time without being close to a Lysenko bottle opening in the sampling and analysis process, and reading can be realized without taking out a Lysenko bottle from a stainless steel protective sleeve in the prior art, and the safety and co
