Description

Technical Field

[0001] This utility model relates to the field of nitrogen pressure testing technology, specifically a nitrogen pressure testing skid. Background Technology

[0002] Currently, a nitrogen pressure test skid is a support device for nitrogen testing. When liquid nitrogen is used, it is necessary to test whether its pressure meets the standard. After meeting the standard, it is discharged after being vaporized by a vaporizer. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of nitrogen pressure test skids.

[0003] The authorization announcement number "CN219776974U" describes "a nitrogen pressure testing skid, including a base, on which a vaporizer, a first cryogenic liquid pump, a second cryogenic liquid pump, and a valve group are positioned and installed. The valve group connects the positions of the first and second cryogenic liquid pumps. Both the first and second cryogenic liquid pumps are connected to inlet pipes, and hydraulic instruments are installed on the inlet pipes. A first connecting pipe connects the first cryogenic liquid pump to the vaporizer, and a second connecting pipe connects the second cryogenic liquid pump to the vaporizer. A mounting base is positioned at the bottom of the vaporizer. The nitrogen pressure testing skid of this utility model is equipped with two sets of liquid pumps, and the two sets of liquid pumps can be switched between each other. When one set of liquid pumps malfunctions, it can switch to the other set of liquid pumps to continue working, improving work efficiency and better performing pressure testing and vaporization operations on liquid nitrogen."

[0004] The aforementioned patent allows for switching between two sets of liquid pumps. When one set of liquid pumps malfunctions, the other set can be switched to continue working, improving efficiency and enabling better pressure testing and vaporization of liquid nitrogen. However, in practice, when the vaporizer vaporizes nitrogen, the high-pressure nitrogen will suddenly depressurize, resulting in a momentary low temperature due to the Joule-Thomson effect. If this low temperature is not utilized, it will cause unnecessary waste. Utility Model Content
