Description

Technical Field

[0001] This utility model relates to the field of sodium pressure transmitter technology, and specifically to a packaging device for packaging sodium pressure transmitters. Background Technology

[0002] In the nuclear power field, the fourth-generation sodium-cooled fast reactor is a fast neutron reactor that uses sodium as a coolant. Liquid sodium absorbs and transfers the heat generated in the nuclear reactor, transferring this heat to a heat exchanger, ultimately converting the heat into electrical energy. The liquid sodium in the reactor's sodium pool loop is typically a sodium-potassium alloy. Sodium pressure transmitters are mainly used for pressure detection in the liquid sodium loop, featuring high temperature resistance, corrosion resistance, and high measurement accuracy. Sodium pressure transmitters generally employ a remote-type pressure transmitter with a capillary tube. The cavity formed by the measuring diaphragm and capillary tube is filled with a high-temperature resistant pressure-conducting fluid. During pressure measurement, to prevent diaphragm rupture leading to leakage of the high-temperature pressure-conducting fluid, which could contaminate the sodium loop and pose safety hazards, the sodium pressure transmitter is filled with a sodium-potassium alloy. Sodium-potassium alloy is liquid at room temperature and reacts violently with air and water. Even a single gram of sodium-potassium alloy can cause a fire or even an explosion. Therefore, addressing the safety concerns of sodium pressure transmitters in the event of damage, leakage, combustion, or explosion during transportation and storage is extremely important. Furthermore, the measuring diaphragm of sodium pressure transmitters is also susceptible to impact damage due to its thinness. Clearly, conventional packaging materials and methods are insufficient to meet the transportation and storage requirements of sodium pressure transmitters.

[0003] Therefore, how to safely package, transport, and store sodium pressure transmitters has become an urgent problem to be solved in this field. Utility Model Content
