Liquid ammonia sampling device

The invention relates to a liquid ammonia sampling device, and relates to the field of liquid ammonia. The liquid ammonia sampling device comprises a base, a steel cylinder sampling tank and a liquid ammonia temporary storage tank are arranged above the base, four pulleys are fixedly connected to the lower surface of the base, a sealing cover is arranged above the steel cylinder sampling tank, a liquid outlet valve and a liquid inlet valve are arranged on the upper surface of the sealing cover, and one end of the liquid inlet valve is connected with a liquid nitrogen transfer seat. According to the liquid ammonia sampling device, under the action of the shielding liquid limiting assembly, when appropriate liquid ammonia is stored in the steel cylinder sampling tank and redundant liquid ammonia enters the liquid ammonia temporary storage tank, the situation that the steel cylinder sampling tank is unstable due to excessive filling of liquid ammonia, and consequently danger is generated is avoided, and under th
