<p>A rotary compensating device used in a pipe under high pressure comprises an inner pipe (1), a sealing gland (3), a sealing seat (5) and a connecting pipe (7). One end of the inner pipe (1) is inserted into the connecting pipe (7), and the connecting pipe (7) fixedly connects with one end of the sealing seat (5) and installs on the outer surface of the inner pipe (1). The inner pipe (1) is provided with an annular outer boss (8), and the sealing seat (5) is provided with an annular inner boss (9). The sealing gland (3) is installed on the outer surface of the inner pipe (1) and inserted into the other end of the sealing seat (5) to abut against the torus sealing member (4). The sealing gland (3) connects with the sealing seat (5) via a connecting member (2). A sealing cavity is formed between the sealing seat (5) and inner pipe (1), and an end face sealing member (6) is installed in the sealing cavity. The rotary compensating device solves the leakage problem exists in the high temperature and high pressure media pipe and widens the application range of the rotary compensating device.</p> |
