High-temperature and high-pressure torque testing device

A high-temperature and high-pressure torque testing device provided by the present invention comprises a high-temperature and high-pressure sealing shell, a heating device, a positioning body, a torsion linkage structure and a torquemeter, the outer side of the high-temperature and high-pressure sealing shell is covered with the heating device, an inner cavity is arranged in the high-temperature and high-pressure sealing shell, and the positioning body is fixedly connected with the inner cavity. A torsion linkage structure is arranged on an inner cavity at the bottom end of the positioning body, one end of the torsion linkage structure is rotatably connected with the inner cavity, and the other end penetrates through the high-temperature and high-pressure sealing shell to be fixedly connected with a torquemeter. The device has the beneficial effects that a simulated underground high-temperature and high-pressure working environment can be formed, and the performance of communication, control, torque output an
