Abstract

The invention discloses a filling joint with easy sealing and a nondisclosure sealing surface. The filling joint comprises a liquid filled pipe. Sealing threads and an installation seat are respectively arranged at both ends of the liquid filled pipe, and a connecting body is arranged at the middle part of the liquid filled pipe. In the invention, a threaded sealing mode is adopted, and therefore, sealing is simple and reliable; in addition, the sealing surface is not exposed outsides, thereby enabling the sealing surface not to be easy to corrode.

Description

Technical field [0001] The invention relates to a filling joint for filling low-temperature liquefied gas such as liquid oxygen, liquid argon, and liquid nitrogen. Background technique [0002] At present, the traditional filling joints have a claw-shaped structure, which is not easy to seal. Moreover, the used seal is a hard seal, and the sealing surface is exposed to the outside for a long time. It is easy for dirt to adhere to the sealing surface and cause leakage; moreover, the filling joint The mounting holes are all fixed holes, which are not easy to adjust and inconvenient to install. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a filling joint which is very easy to seal and the sealing surface is not exposed. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a filling joint, comprising: a filling pipe, the two ends of the filling pipe are respect...
