Refrigerant processing gas leakage detection device

The invention discloses a refrigerant processing gas leakage detection device, and belongs to the field of refrigerant processing. The refrigerant processing gas leakage detection device comprises a sealing shell, a detection separation ring, a pressure part, a prompt part and a pair of positioning parts, a cylindrical detection cavity is formed in the sealing shell, an axial opening is formed in the detection cavity, and the detection separation ring is fixed to the inner wall of the detection cavity in the radial direction of the detection cavity; the pressure part is arranged along the outer circumference of the detection cavity; when the output port of the tank body leaks, the detection block is driven to operate through the air pressure difference value, after a pressure block on the driving block is impacted by air in a straight face, the limiting assembly is triggered to act, the detection block stops moving, the direction of the detection block is the leakage position of the output port of the tank bo
