Beschreibung
Zusammenfassung:	The invention provides a dynamic sealing device for connecting pipelines. The dynamic sealing device comprises a fixed sleeve, an inner sealing plate, a left baffle, a right baffle, an outer sealing plate, a rotating sleeve, and lubricating oil; the inner and outer sealing plates comprise sealing devices and metal plates; the sealing devices with labyrinth holes are fixed on two sides of the metalplates, and are coated with lubricating oil; the inner edge of the inner sealing plate is integrally and fixedly connected with the rotating sleeve, and the outer edge of the outer sealing plate is integrally and fixedly connected with the fixed sleeve; and the inner sealing plate 2 and the outer sealing plate 6 are fixedly installed on the rotating sleeve 8 and the fixed sleeve 1 in sequence. According to the dynamic sealing device for connecting the pipelines, the technologies of the seal between the sealing devices between the inner sealing plate and the outer sealing plate, the seal performance generated due to t
