冷却液自動積込回収装置。 In the loading piping for loading coolant from the coolant tank to a cryogenic liquid carrier, a bypass pipe is installed in the coolant feed valve installed downstream of the tank main valve of the coolant tank, and a restriction orifice and a coolant are installed in this bypass pipe. A down valve is provided, and a temperature control valve with one end open and the other end of the pressure control valve are connected to the upstream side of the arm cutoff valve at the tip of the loading pipe.
During cool-down, an open signal is output to the cool-down valve, and a control signal is output to send liquid from the coolant tank to the loading pipe at a predetermined rate via the restriction orifice of the bypass pipe for cooling. When loading, a close signal is output to the temperature control valve and pressure control valve at a predetermined temperature, and an open signal is output to the arm cutoff valve and coolant supply valve. After loading is completed, the coolant is stopped by the close signal of the arm cutoff valve. 1. An automatic cooling liquid loading and recovery device for a cryogenic liquid carrier, characterized in that it is provided with a control device that outputs a control signal to open an atmosphere release valve of the tank and recover the cooling liquid in the loading pipe under reduced pressure in the cooling liquid tank.
