The invention relates to the field of rotary joints, in particular to a rotary joint for conveying high-pressure abrasive water mixed liquid, which comprises a main shaft arranged in a shell, a filter section is connected to an inlet of the main shaft, and the filter section comprises an axial channel for the water mixed liquid to pass through and a radial channel for filtering abrasive in the water mixed liquid. A sealing supporting sleeve and a high-pressure sealing assembly are coaxially arranged outside the main shaft, the sealing supporting sleeve and the high-pressure sealing assembly are matched with the shell, and a shell cavity is divided into a first sealing cavity used for installing a bearing, a second sealing cavity used for installing a bearing and a third sealing cavity used for containing filtered water mixed liquid. The rotary joint can be suitable for conveying abrasive jet, and the service life of the rotary joint is greatly prolonged. 本发明涉及旋转接头领域，具体是一种输送高压磨料水混液的旋转接头，包括布置在壳体内的主轴，主轴入口处连接有过滤段
