[0002] An ambient air vaporizer (also known as an ambient air vaporizer) is a device that uses natural convection air in the atmosphere as a heat source to heat and vaporize low-temperature liquid gases (such as liquefied natural gas LNG, liquid oxygen LOX, liquid nitrogen LIN, liquid argon LAR, etc.) into room temperature gases.

[0003] The prior art discloses a mobile air-temperature vaporizer with publication number CN219346220U, which includes an air-temperature vaporizer body and a support frame. The air-temperature vaporizer body includes a fixed frame, finned tubes, connecting pipes, a liquid inlet pipe, and an air outlet pipe. The support frame is located at the bottom of the fixed frame, and the bottom of the support frame is equipped with casters. Fixed frames are provided on both sides of the fixed frame. The liquid inlet pipe and the air outlet pipe are respectively located at both ends of the finned tubes. In the process of using the air-temperature vaporizer, it is convenient to move or fix the device according to needs, which facilitates intelligent use, simplifies the operation process, and meets actual needs.

[0004] The aforementioned liquid inlet pipe and gas outlet pipe are respectively located at both ends of the finned tube. When the liquid inlet pipe and gas outlet pipe are connected to the pipeline, gas or liquid may leak from the connection point, requiring a lot of time for maintenance. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: The inlet and outlet joints of the ambient air vaporizer with a double-sealed structure include an ambient air vaporizer 1 and a protective frame 2. A limit cover 3 is installed on the top of the protective frame 2, and a support base 4 is installed on the bottom of the protective frame 2. The ambient air vaporizer 1 is installed on the inner wall surface of the protective frame 2.

[0020] The ambient air vaporization device 1 includes an ambient air vaporizer body 11, a connecting pipe 12, and a connecting assembly 13. The connecting pipe 12 is fixedly connected to the left end inlet and outlet of the ambient air vaporizer body 11. The ambient air vaporizer body 11 is installed on the inner wall surface of the protective frame 2. The second limiting cover 3 is installed on the top of the ambient air vaporizer body 11, and the second support base 4 is installed on the bottom of the ambient air vaporizer body 11. The protective frame 2, the second limiting cover 3, and the second support base 4 can clamp and fix the ambient air vaporizer body 11, and can keep the ambient air vaporizer body 11 stable. The connecting assembly 13 is threadedly connected to the left side surface of the connecting pipe 12.

[0021] The connecting assembly 13 includes a first sealing pipe 131, a threaded rod 132, a second sealing pipe 133, a helical spring 134, a limiting block 135, a sealing ring 136, a first limiting cover plate 137, a first support base 138, and a fastening threaded rod 139. The threaded rod 132 is fixedly connected to the left and right ends of the first sealing pipe 131. The sealing rings 136 are installed at the left and right ends of the first sealing pipe 131. There are four sealing rings 136, with two sealing rings 136 forming a group. The two groups of sealing rings 136 are distributed at the left and right ends of the first sealing pipe 131, with two sealing rings on the same side. The root sealing ring 136 comes in two sizes. The small sealing ring 136 is located on the inward side of the large sealing ring 136. The four sealing rings 136 can provide a double seal for the connection between sealing pipe one 131 and sealing pipe two 133. Sealing pipe two 133 is threaded to the right side of sealing pipe one 131. The helical spring 134 is installed on the left side of the limiting block 135. The limiting block 135 is threaded to the left end of the connecting pipe 12. Sealing pipe two 133 is threaded to the left side of the connecting pipe 12. The connecting pipe 12 and the limiting block 134 are connected to the left side of the connecting pipe 12. A sealing ring is installed at the connection of the insert 135 to seal the connection between the limiting insert 135 and the connecting pipe 12. The limiting insert 135 is slidably connected to the right side of the second sealing pipe 133. The second sealing pipe 133 is movably connected to the right side surface of the sealing ring 136 and to the threaded surface of the threaded rod 132. The second sealing pipe 133 and the first sealing pipe 131 are sealed by the sealing ring 136. The first limiting cover 137 is movably connected to the middle position of the first sealing pipe 131. The support base 138 is movably connected to the top of the support base 138. The support base 138 is installed on the right side of the support base 2 4. The support base 138 is movably connected to the middle position of the sealing pipe 131. The sealing pipe 131 is threadedly connected to the top of the fastening threaded rod 139. The support base 138 and the limiting cover 137 are locked and fixed by the fastening threaded rod 139, so as to clamp and fix the sealing pipe 131 and prevent the sealing pipe 131 from shaking. The fastening threaded rod 139 is fixedly connected to the front and rear ends of the support base 138.

[0022] When in use, rotating the nut causes it to rotate on the left side surface of the limiting plug 135, causing the limiting plug 135 to disengage from the connecting pipe 12, loosening the connection between the sealing pipe 133 and the connecting pipe 12.

[0023] Then rotate the nut, and the nut rotates on the surface of the fastening threaded rod 139, which loosens the connection between the limit cover plate 137 and the support base 138, and pulls the limit cover plate 137 to move upward.

[0024] The limiting cover plate 137 moves up and down along the surface of the fastening threaded rod 139 and the support base 138, so that the limiting cover plate 137 can be separated from the sealing pipe 131, thereby facilitating the disassembly and replacement of the sealing pipe 131.

[0025] Rotate the nut, and the nut will rotate on the surface of the threaded rod 132, causing the connection between the sealing pipe 133 and the threaded rod 132 to loosen.

[0026] Push the limiting plug 135 to move to the left, and the limiting plug 135 slides on the surface of the sealing pipe 2 133, so that the spiral spring 134 can be compressed between the sealing pipe 2 133 and the limiting plug 135, and at the same time the limiting plug 135 can be disengaged from the connecting pipe 12.

[0027] Pulling the sealing pipe 131 upwards causes the sealing pipe 131 to move the sealing pipe 2 133 upwards via the threaded rod 132, thereby detaching the sealing pipe 131 from the support base 138 and facilitating the disassembly and replacement of the sealing pipe 131 and the sealing pipe 2 133.

[0028] Next, pull the second sealing pipe 133 to the right. The second sealing pipe 133 slides along the right side surface of the first sealing pipe 131, so that the second sealing pipe 133 is separated from the first sealing pipe 131. This allows the sealing ring 136 between the first sealing pipe 131 and the second sealing pipe 133 to be disassembled and replaced. Repairing the sealing ring 136 can increase the service life of the second sealing pipe 133 and the first sealing pipe 131.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
