Problems solved by technology

The pipeline universal joints used in the prior art usually use sealing oil to realize the sealing compensation when the joint rotates, and the problem of sealing oil leakage is prone to occur during use, resulting in the contamination of the circulating medium in the pipeline. Moreover, in the prior art The materials usually used in pipeline universal joints have poor high temperature resistance, and it is difficult to meet the environmental requirements of plateau areas.

Embodiment 1

[0032] A pipeline universal self-sealing joint, comprising a ball joint body 1, a nut 2, a joint body 8 and a sealing assembly; wherein the ball joint body 1, the nut 2 and the joint body 8 form a sealed space, and the sealed space A sealing assembly is installed inside, the nut 2 and the joint body 8 are connected by threads, and a bevel is set between the nut 2 and the ball joint body 1 so that the ball joint body 1 can tilt and swing in the axial direction; the seal assembly runs along the ball joint to the joint The body direction includes in turn: adjusting ring 1 3, adjusting ring 2 4, sealing ring 1 5, lining ring 1 9, lining ring 2 6, sealing ring 2, and adjusting ring 3 7.

[0033] Preferably, the side of the adjusting ring 1 3 and the adjusting ring 2 4 close to the ball joint body 1 has the same inclination angle as the bevel, and the inclination angle is 15-20°, preferably 15.5°.

[0034] Preferably, the adjusting ring one 3 and the adjusting ring two 4 are respect...

Abstract

The invention discloses a universal self-sealing joint for a pipeline. The universal self-sealing joint comprises a spherical joint body, a nut, a joint main body and a sealing assembly. According to the universal self-sealing joint for the pipeline, the spherical joint body, the nut, the joint main body and the sealing assembly are adopted to compensate the expansion and contraction quantity of a heat collecting pipe, the universal self-sealing joint has high temperature resistance and pressure resistance, and meanwhile it is guaranteed that leakage is avoided in the joint rotating process.

Description

technical field [0001] The invention relates to the field of pipeline sealing, in particular to a pipeline universal self-sealing joint. Background technique [0002] The pipeline universal self-sealing joint involved in this application is applied to the solar rotary flap in the solar concentrated solar thermal power generation (CSP) equipment, specifically for the sealing and connection of pipeline joints, and the equipment is set in a place with abundant solar energy resources. Delingha City, Delingha City is an important transportation hub and commodity distribution center in the west of Qinghai. It is a transportation hub connecting Tibet in the south, Gansu in the north, Xinjiang in the west, and the provincial capital in the east. However, the environment in the plateau area is harsh. The local altitude is about 3000m-3100m, and the natural slope is about 3-4%. The main meteorological disasters in Delingha City include drought, snow disaster, hail, mountain torrent, l...
