Description

Technical Field

[0001] The utility model relates to the technical field of liquid outlet pipes, in particular to a liquid outlet pipe with good anti-corrosion performance. Background Art

[0002] A cryogenic storage tank is a vertical or horizontal double-layer vacuum insulated storage tank for storing liquid oxygen, nitrogen, argon, carbon dioxide, gasoline and other media. Currently, there is no anti-vortex flow device on the liquid outlet of the cryogenic storage tank on the market. When the liquid in the cryogenic storage tank is discharged, a vortex will be formed. The vortex will change the direction of the liquid flow rate, causing the flow rate to pulsate, resulting in pressure loss, and causing the liquid flow rate to drop rapidly; when the cryogenic storage tank discharges liquid, it is usually discharged through a liquid outlet pipe. Patent No. CN202223532692.3 provides a liquid outlet pipe structure for a cryogenic storage tank, and an adjustable anti-vortex flow device is provided on the liquid outlet pipe to adjust the liquid outlet flow rate of the liquid outlet pipe.

[0003] The above disclosed liquid storage tank has some shortcomings in its structural design. For example, the temperature of the fluid cannot be detected and the corrosion resistance of the pipeline itself cannot be guaranteed. Therefore, we design a liquid outlet pipe with good corrosion resistance. Utility Model Content
