[0002] A pressure vessel is a sealed container that can withstand pressure. Pressure vessels are widely used. They play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. They are most commonly used in the chemical industry and petrochemical industry. When using them, conversion joints are required to connect pressure gauges.

[0003] For example, the Chinese authorized patent with announcement number CN208953195U (a special conversion joint for pressure gauge): it includes a right-angle joint body, a joint channel is provided in the joint body, one end of the joint body is provided with an end A that is sealed and abutted with the pressure gauge, and the other end is provided with an end B that is sealed and abutted with the transition joint, the transition joint is sealed and connected to the detected part, one end of the joint body corresponding to the end A is movably provided with a locking nut A that cooperates with the end A to seal and fasten the joint body to the pressure gauge, and one end of the joint body corresponding to the end B is movably provided with a locking nut B that cooperates with the end B to seal and fasten the joint body to the transition joint, a damping channel is provided between the two ends of the joint channel, and the diameter of the damping channel is smaller than the diameter of the joint channels at the two ends. By adopting a right-angle structure and a movable locking nut connection and fastening form, convenient installation and free rotation adjustment of the installation angle are achieved, which is very practical; by designing a damping channel in the joint channel, it can effectively play a damping effect, that is, reduce and reduce the oil pressure impact, thereby reducing the impact on the pressure gauge and extending the service life.

[0004] However, the pressure gauge conversion joint in the above-mentioned prior art has a relatively simple interface structure and only has two connections for the container and the pressure gauge, which affects its practicality; therefore, it does not meet the existing needs. We have proposed a conversion joint suitable for installing a pressure vessel pressure gauge. Utility Model Content
