Abstract

The invention relates to a rotary joint, in particular to a connecting sealing member for conveying a fluid medium from a static pipeline to a swinging or rotating device, and belongs to the technical field of sealing devices. According to the technical scheme, the rotary joint with a temperature difference zone structure comprises a shell, a cylindrical spring mounted at the inner bottom of the shell and an outer tube positioned in the shell. A cylindrical ring is embedded on the end surface of the cylindrical spring; the outer tube is mounted in the inner hole of the cylindrical ring; and an O-shaped sealing ring is arranged in an inner hole at the tail part of the outer tube. The invention has the advantages of artistic and smooth outer appearance, stable rotation of the outer tube, temperature difference zone structure, reliable compensation on seal abrasion, good sealing performance and long service life.

Description

Technical field [0001] The invention relates to a rotary joint, in particular to a connecting sealing component used for fluid medium input from a stationary pipeline to a rotating equipment, and belongs to the technical field of mechanical seals. Background technique [0002] Rotary joints are connecting sealing parts that input fluid media (liquid, gas, etc.) from stationary pipelines to rotating equipment. It is a sealing device that solves running, emitting, dripping, and leaking, saves energy, protects the environment, and improves working conditions. The rotary joint produced by the prior art has the shortcomings of rough shape, crude shape, poor rotation stability of the outer tube, etc., resulting in uneven wear; and because there is no temperature difference zone, it is easy to produce spring deformation or fracture accidents, resulting in failure of the sealing of the input medium. Run, leak, drip, and leak, and even cause serious pollution accidents to the production e...
