Description

Technical Field

[0001] The utility model relates to the technical field of air-temperature vaporizers, and particularly relates to a bridge connecting element for an air-temperature vaporizer. Background Technique

[0002] An air-temperature liquid nitrogen vaporizer is a device used to convert liquid nitrogen into gaseous nitrogen. When injecting or spraying liquid nitrogen onto the vaporizer, it utilizes the heat of the environment to rapidly evaporate and vaporize the liquid nitrogen, thereby generating nitrogen. Currently, when connecting pipes of an air-temperature liquid nitrogen vaporizer, most connections are directly between pipes, lacking a connection structure for the pipes, resulting in an insecure connection between the pipes and inconvenient use. The utility model patent with the application number CN202322698261.2 proposes a pipeline connection structure for an air-temperature liquid nitrogen vaporizer, including: a liquid nitrogen vaporizer body, with a pipeline body arranged on one side of the liquid nitrogen vaporizer body; a connecting pipeline... to form a second seal; since the first threaded rod is threadedly connected to the through groove, the fixed arc plate can be driven to move downward to form clamping and fixation, avoiding displacement. In the above patent, multiple threaded rods are used for the installation of the connection part inside the device, with general stability. Moreover, the user needs to screw the threaded rods multiple times, which is time-consuming and laborious, and cannot well connect the first sealing ring and the second sealing ring, easily causing gas leakage from the connection between the pipeline body and the connecting pipeline, reducing the practicality of the device. Therefore, a bridge connecting element for an air-temperature vaporizer is provided to solve the above problems. Summary of the Utility Model

[0027] Please refer to Figures 1 to 4 , the present utility model provides a bridge connection element for an ambient temperature vaporizer, including the body 1 of the ambient temperature liquid nitrogen vaporizer. A pipeline body 2 is fixedly connected to the outside of the body 1 of the ambient temperature liquid nitrogen vaporizer.
