ス缶安全装置。A cylindrical space is formed in the opening/closing device attached to the service can, and the device is provided with a first flow path that communicates with the inside of the service can and an outlet side flow path that communicates with this. The other end of the first channel passes through the upper surface of the cylindrical space, and another second channel passes through the outer peripheral surface of the cylindrical space and is connected to the first channel. The cylindrical space communicates with each other, and further a through hole is formed from the opposing cylindrical space on an extension of the second flow path to the outside of the switchgear,
On the other hand, a safety valve is fitted in the cylindrical space, the safety valve having a through hole that allows communication between the second flow path and a through hole penetrating from the outer peripheral surface of the cylindrical space to the outside of the switchgear. A spring is compressed between the lower side of the cylindrical space and the lower surface of the safety valve so that the safety valve can reciprocate in the axial direction of the cylindrical space, and the elasticity of the spring The safety valve can normally be maintained elevated in a position where its through hole does not communicate with the second flow path and the through hole on the lower side of the cylindrical space, and the cylindrical space has no other flow path than the first flow path. Set to an elasticity value that allows the safety valve to be lowered to a position where the through hole of the safety valve can communicate with the second flow path and the through hole on the outer peripheral surface of the cylindrical space when a fluid pressure of a certain value or more is applied from the end. A refrigerant service can safety device characterized by:
