Problems solved by technology

Although in most cases, the existing pipe joints can be used to splice various required piping systems according to the needs, in reality, there are still some places that require parallel piping systems, such as solar panel collectors and heating pieces, it is difficult to splice multi-branch parallel piping systems with existing pipe joints
When splicing a multi-branch parallel pipeline system, it is inconvenient to connect multiple branch pipes between two main pipes, and it is also inconvenient to solve the length change of each branch pipe due to thermal expansion and contraction

Embodiment 1

[0020] Figure 4 Among them, the parallel pipeline system is composed of two multi-way pipe expansion joints with inner wire extruded cover rings and 7 stainless steel pipes. The multi-way pipe expansion joints with inner wire extruded cover rings are provided with 7 branch pipes. The two ends of the pipe pass through the inner wire extruded cover ring 5 and the sealing ring 4 in sequence respectively, and are inserted into the outer wire expansion joint body 3, and the inner wire extruded cover ring 5 is tightened, and the inner wire extruded cover ring 5 and the outer The extrusion of the wire expansion joint body 3 makes the sealing ring 4 closely connected with the outer wire expansion joint body 3 .

Embodiment 2

[0022] Figure 7 Among them, a parallel pipeline system is composed of two multi-way pipe expansion joints extruded by outer wires and 8 stainless steel pipes. The inner wire expansion joint body 9 is provided with 8 branch pipes, and the two ends of the stainless steel pipes are in turn Correspondingly pass through the outer wire extrusion cover ring 11 and the sealing ring 10, and insert it into the inner wire expansion joint body 9, tighten the outer wire extrusion cover ring 11, and pass the outer wire extrusion cover ring 11 and the inner wire expansion joint body 9 Squeeze, so that the sealing ring 10 is closely connected with the inner wire expansion joint body 9 .

Abstract

The invention discloses an expansion joint of a multi-way pipeline. By adoption of the expansion joint of the multi-way pipeline, multiple branches of a parallel-connection pipeline system can be conveniently jointed and the length variation can be automatically compensated and absorbed. The multi-way pipeline body is composed of a straight-through main pipe, a main pipe connector A, a main pipe connector B and more than two branch pipes. Each branch pipe is provided with expansion joints. The expansion joint of the multi-way pipeline is mainly used for jointing various parallel-connection pipeline systems.

Description

technical field [0001] The invention relates to a pipe joint, in particular to a multi-way pipe joint. Background technique [0002] Piping systems are widely used in daily life and industry, in which various pipe joints play a very important role. Although in most cases, the existing pipe joints can be used to splice various required piping systems according to the needs, in reality, there are still some places that require parallel piping systems, such as solar panel collectors and heating It is difficult to splice multi-branch parallel piping systems with existing pipe joints. When splicing multi-branch parallel pipeline systems, it is inconvenient to connect multiple branch pipes between two main pipes, and it is also inconvenient to solve the length change of each branch pipe due to thermal expansion and contraction. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and provides a multi-way pipe expansion joint, which can ...
