Abstract
The utility model discloses a kind of sealing structure and high temperature high pressure swivel joint based on double-spring sealing for high temperature high pressure swivel joint. Among them, swivel joint includes seat body, with the fixed cover of seat body, outer tube is rotationally arranged in the seat body by bearing, dynamic seal ring is fixed in the outer tube by keyway, and static seal ring is supported in the cover, dynamic seal ring and static seal ring are sealed by adhering, dynamic seal ring is supported in the outer tube by first spring, static seal ring is supported in the cover by second spring, dynamic seal ring is supported by the support force of first spring and static seal ring is supported by the support force of second spring parallel and relative. Dynamic seal ring and static seal ring in the sealing structure of the utility model are supported by spring respectively, and double-spring realizes 2 sides bidirectional simultaneous pressurization to sealing mechanism, so that the adhering pressure between dynamic seal ring and static seal ring is greater, and the sealing effect is improved. Because pressure is greater, dynamic seal ring and / or static seal ring recommend to select the material of harder and more wear-resistant texture, to reduce abrasion, prolong service life.
