Abstract

The application relates to the technical field of flange pipe detection, in particular to a flange pipe detection joint for high-temperature medium pressure detection, which comprises a joint body, a pressure leading part and a pressure detection main body. A circulating bin and an external circulating pipe are arranged in the joint body, and the joint body is filled with cooling medium. The bottom of the joint body is provided with a butt joint part and a rotating part formed by rotatingly connecting an impeller. When the joint is connected with the flange pipe, the high-temperature medium flowing in the pipe drives the impeller to rotate, the convex part on the impeller periodically pushes the movable plate in the circulating bin, the movable plate reciprocates, and the cooling medium is driven to form a circulating flow between the circulating bin and the circulating pipe. The circulating pipe is arranged in the heat dissipation fins outside the joint, the special buffer part of the circulating pipe periodically expands due to the medium pressure fluctuation, the elastic fins are excited to high-frequency micro-vibration, the heat dissipation efficiency is effectively improved, and the measurement accuracy and reliability of the pressure detection main body under high-temperature working conditions are remarkably improved.
