Embodiment

[0013] The internal pressure rubber self-sealing flange connection pipe universal joint includes an outer sleeve and an inner sleeve. One end of the inner sleeve is sleeved on one end of the outer sleeve. The socket end of the inner sleeve is provided with a spherical tube part. The two ends of the outer spherical surface are respectively matched with the spherical surfaces on the inner wall of the outer casing and the inner wall of the compression flange, and the compression flange is connected with the outer casing by bolts to fix the spherical tube part and allow the spherical tube part to rotate freely at a certain angle , to achieve universal compensation, the compression flange, the inner wall of the outer casing and the middle part of the outer spherical surface of the spherical tube form a closed cavity, a sealing ring is set in the cavity, and an axial section is set on the inner ring surface of the sealing ring It is a dovetail-shaped or T-shaped annular internal pres...

Abstract

An internal compression type rubber self-sealing flange connection pipeline universal joint comprises an outer sleeve and an inner sleeve. One end of the inner sleeve is sleeved with one end of the outer sleeve, and a sealing device is arranged on the sleeving portion. The universal joint is characterized in that the sleeved end of the inner sleeve is provided with a sphere pipe part; the two ends of the outer spherical surface of the sphere pipe part are matched with a spherical surface on the inner wall of the outer sleeve and a spherical surface arranged on the inner wall of a pressing flange respectively; the pressing flange is connected with the outer sleeve through a bolt to fix the sphere pipe part; the sphere pipe part can freely rotate by a certain angle to achieve universal compensation; the pressing flange, the inner wall of the outer sleeve and the middle of the outer spherical surface of the sphere pipe part form a closed cavity; a sealing ring is arranged in the cavity; an annular inner pressing cavity with the axial section being in a swallow-tail shape or a T shape is formed in the inner ring face of the sealing ring; the outer surface of the sealing ring makes contact with the pressing flange, the inner wall of the outer sleeve and the outer surface of the sphere pipe part; a certain number of inner pressing through holes are formed in the pipe wall, opposite to the opening of the annular inner pressing cavity, of the sphere pipe part, so that the annular inner pressing cavity is communicated with the inner cavity of the inner sleeve.

Description

technical field [0001] The invention relates to a pipeline compensator, in particular to an internal pressure rubber self-sealing flange connecting pipeline universal joint. Background technique [0002] The pipeline compensator is an indispensable equipment in the laying of the national pipeline network. For a long time, in the compensation connection of the pipeline system, the sleeve type compensator (also known as the sleeve type expansion joint) has been widely used. According to the specific structure Some sleeve-type compensators can realize axial thermal expansion and contraction compensation, and some spherical sleeve-type compensators can realize angle compensation. Generally speaking, sleeve-type compensators have a jacket with flanges at both ends tube and an inner sleeve inserted into the outer sleeve. There is a packing chamber between one end of the outer casing and the inner casing, and the sealing material is filled in the packing chamber, and the sealing m...
