Description

Technical Field

[0001] The utility model relates to the technical field of liquid nitrogen vaporization and voltage stabilization, and more specifically, to a liquid nitrogen vaporization and voltage stabilization device. Background Art

[0002] In the existing technology, it is often difficult to achieve effective pressure stability during the operation of the liquid nitrogen vaporization device, which affects the transportation and use safety of liquid nitrogen to a certain extent.

[0003] First, during the vaporization process of liquid nitrogen, due to the phase change characteristics of liquid nitrogen, its vaporization process is often accompanied by fluctuations in temperature and pressure. Existing liquid nitrogen vaporization devices may have design defects, such as the lack of an effective pressure regulation mechanism, delayed response of the pressure control system, or a limited regulation range. These problems may cause large pressure fluctuations during the vaporization of liquid nitrogen, thereby affecting the normal operation of the delivery pipeline and equipment. In addition, pressure fluctuations may also cause leakage of liquid nitrogen, increasing operational risks.

[0004] Secondly, the pressure fluctuations during the vaporization of liquid nitrogen also have a certain impact on the safety of transportation and use. During the transportation process, the pressure fluctuations of liquid nitrogen may cause water hammer in the pipeline, thereby damaging the pipeline and equipment. At the same time, during use, the pressure fluctuations of liquid nitrogen may cause unstable operation of the equipment, affecting the performance and life of the equipment. In addition, pressure fluctuations may also affect the purity and quality of liquid nitrogen, thereby affecting the effect of downstream applications. Utility Model Content

A pressure stabilizing mechanism is arranged on the tank body 1, and the pressure stabilizing mechanism comprises a pressure stabilizing tube 2, an external tube 3, a sealing sleeve 4, a pull rod 5, a rotating disk 6, a spring 7, a one-way mechanism, a rotating mechanism, an extending plate 8 and an inserting rod 9. The pressure stabilizing tube 2 is connected and mounted on the tank body 1, the sealing sleeve 4 is mounted on the pressure stabilizing tube 2, the pull rod 5 is slidably connected in the sealing sleeve 4, the rotating disk 6 is mounted on the pull rod 5, the two ends of the spring 7 are respectively connected to the rotating disk 6 and the pressure stabilizing tube 2, one end of the external tube 3 is connected to the external device, and the other end of the external tube 3 is connected to the pressure stabilizing tube 2, the one-way mechanism and the rotating mechanism are mounted on the pull rod 5, the extending plate 8 is mounted on the rotating mechanism, the inserting rod 9 is mounted on the extending plate 8, a plurality of the inserting rods 9 are arranged, and the lengths of the plurality of the inserting rods 9 increase successively, and each inserting rod 9 is provided with a round head 10, the rotating mechanism It includes a hexagonal section 11 and a control plate 12. The two ends of the hexagonal section 11 are respectively connected to the pull rod 5 and the extension plate 8. The control plate 12 is provided with a hexagonal groove 13. The hexagonal section 11 is stuck in the hexagonal groove 13. The control plate 12 is provided with a threaded sleeve 14. The threaded sleeve 14 is threadedly connected in the one-way tube. The control plate 12 is provided with a plurality of insertion holes 15. The insertion rod 9 is slidably connected in the insertion hole 15. The one-way mechanism includes a receiving sleeve 16 and a pressing plate 17. A socket sleeve 16 is installed in the voltage-stabilizing tube 2, a pressure plate 17 is installed on the pull rod 5, the pressure plate 17 and the socket sleeve 16 are coaxially arranged, a groove 18 is opened on the pressure plate 17, and the groove 18 is pressed in the socket sleeve 16, a guide plate 19 is provided in the voltage-stabilizing tube 2, a guide rod 20 is provided on the extension plate 8, the guide rod 20 and the pull rod 5 are coaxially arranged, the guide rod 20 is slidably connected to the guide plate 19, and a plurality of legs 21 are provided at the upper and lower ends of the tank body 1.

[0032] In this embodiment, when the liquid nitrogen in the tank body 1 vaporizes, the pressure plate 17 on the pull rod 5 is pressed against the receiving sleeve 16 due to the tension of the spring 7. Therefore, the seal between the receiving sleeve 16 and the pressure plate 17 can be released only when the pressure exceeds the elastic force of the spring 7. As the pull rod 5 moves upward, the insertion rod 9 also moves upward. When the pressure exceeds the elastic force of the spring 7, the longest insertion rod 9 is inserted into the insertion hole 15, and then only the other insertion holes 15 can flow. The greater the pressure, the more the pressure plate 17 moves upward, and the more the pressure plate 17 moves upward, the more insertion rods 9 will be inserted into the insertion hole 15. When the pressure exceeds this range, multiple insertion plates will be inserted into the insertion hole 15 at the same time, so it will be closed, avoiding pressure fluctuations. Therefore, the generation of ripples can be prevented in response to pressure fluctuations, so that the pressure returns to a steady state.

[0033] More specifically, when it is necessary to adjust the steady-state range of pressure, it is only necessary to control the relative positions of the control plate 12 and the multiple insertion rods 9. Since the hexagonal segment 11 is slidably connected in the hexagonal groove 13, the rotation of the rotating disk 6 can drive the threaded sleeve 14 to rotate along the voltage-stabilizing tube 2, thereby adjusting the position and completing the adjustment of the voltage-stabilizing range.

[0034] In summary, when the overall equipment is in use or running: when the liquid nitrogen in the tank body 1 vaporizes, the tension of the spring 7 drives the pressure plate 17 on the pull rod 5 to press on the receiving sleeve 16. Therefore, the seal between the receiving sleeve 16 and the pressure plate 17 can be released only when the pressure exceeds the elastic force of the spring 7, and as the pull rod 5 moves upward, the insertion rod 9 also moves upward. When the pressure exceeds the elastic force of the spring 7, the longest insertion rod 9 is inserted into the insertion hole 15, and then only the other insertion holes 15 can flow. The greater the pressure, the more the pressure plate 17 moves upward, and the more the pressure plate 17 moves upward, the more insertion rods 9 will be inserted into the insertion hole 15. When the pressure exceeds this range, multiple insertion plates will be inserted into the insertion hole 15 at the same time, so it will be closed, avoiding pressure fluctuations. Therefore, the generation of ripples can be prevented in response to pressure fluctuations, so that the pressure returns to a steady state.

[0035] When it is necessary to adjust the steady-state range of pressure, it is only necessary to control the relative positions of the control plate 12 and the plurality of insertion rods 9. Since the hexagonal section 11 is slidably connected in the hexagonal groove 13, the rotation of the rotating disk 6 can drive the threaded sleeve 14 to rotate along the voltage-stabilizing tube 2, thereby adjusting the position and completing the adjustment of the voltage-stabilizing range.

[0036] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
