The utility model provides a rotary connecting sealing device, comprising a sealing connecting body and a rotary joint, wherein the sealing connecting body comprises a first through hole, a first joint part and an end face part; the first hole end of the first through hole is positioned on the first joint part; the second hole end of the first through hole is positioned on the end face part; the sealing connecting body is connected with rotating equipment through the end face part; the rotary joint comprises a second joint part; the first hole end comprises internal threads; the second joint part comprises external threads; the first joint part is connected with the second joint part in a sealing manner through the internal threads and the external threads. According to the rotary connecting sealing device, the threaded connection is employed, so that a sealing effect is realized through the threaded structure; the threads are in circumferential rotating connection, so that the rotary joint cannot be separated from the sealing connecting body when the internal pressure is larger; two components, which are connected with each other in a threaded manner, have the same center axis, the coaxiality can be guaranteed when the two components are installed directly, and regulation is unnecessary.
