Description

The present invention relates to a fluid pipeline assembly, and more particularly to a fluid pipeline assembly that can prevent overflow.

A pipeline system for transporting a fluid is a component used in large quantities in the industrial field, and it is common to connect a plurality of pipelines to each other by a pipe or a device, if desired, with a joint. Depending on the type of fluid being transported, the connection method generally includes welding, screw connection.

Welded connections are applied to high pressure fluids due to their high connection strength, and screwed connections are applied to low pressure fluids due to their relatively weak connection strength. However, at the interface between welding and screw connection, corrosion, oxidation, rust, etc. are likely to occur due to long-term exposure or contact with the external environment. To solve this problem, heat shrink tubing, industrial tape or coating layers are generally coated and protected at the interface to avoid direct contact of the interface with the external environment.

Structural compatibility between the coating layer and the tubing must be considered and therefore fillers are generally applied to address the incompatibility between the coating layer and the tubing. However, when filling the filler, it is difficult to observe how much the filling is performed, and if it is overfilled, a phenomenon of outflow occurs. If the filling is insufficient, the filling cannot be completed, which affects the adhesion.

As shown in FIGS. 1A and 1B, the present invention provides a fluid pipeline assembly capable of preventing overflow. The fluid pipeline assembly includes a first pipeline 10, a second pipeline 20, connecting parts 30, and a filler 40. The first line 10 has a first outer wall 11, the second line 20 has a second outer wall 21, the second line 20 is connected to one end of the first line 10, and the connecting component 30 is a first. The first line 10 and the second line 20 are connected. In this embodiment, the first pipe line 10 and the second pipe line 20 are both round pipes and have different diameters. In another embodiment, the first line 10 and the second line 20 are pipe bodies having different cross sections and may have the same or different diameter lengths.

The connecting component 30 includes a casing 31 and a collar 32, the casing 31 includes a first connecting section 311 and a second connecting section 312, and the first connecting section 311 is on the first outer wall 11 of the first pipeline 10. It is fitted and the second connected section 312 is used for fitting the second pipeline 20. In this embodiment, the inner diameter of the casing 31 is larger than the outer diameters of the first pipe line 10 and the second pipe line 20, and the first connecting section 311 of the casing 31 and the first outer wall 11 of the first pipe line 10 are closed. Therefore, it may be arranged by an intermediate fit or a clearance fit, and an annular space 50 is formed between the second connecting section 312 of the casing 31 and the second outer wall 21 of the second pipeline 20. In this embodiment, the casing 31 further includes at least one filler hole 313 provided between the first connected section 311 and the second connected section 312. The annular space 50 has a filling end 51 and an open end 52, the filling end 51 is adjacent to the filler hole 313, and the open end 52 is separated from the filling end 51.

The collar 32 includes a connecting portion 321 and a stop plate 322, the connecting portion 321 includes a protruding portion 3211 and a stretched section 3212, and the protruding portion 3211 extends outward in the radial direction, whereby the second connecting portion 321 is formed. Leaning on the end 3122 of the section 312, the stretched section 3212 extends axially and is connected to the inner wall surface 3121 of the second connected section 312. In this embodiment, the second connecting section 312 includes a threaded structure 3123 because it is provided on the inner wall surface 3121, and includes a male threaded structure 3213 screwed into the extension section 3212 female thread structure 3123. The stop plate 322 extends from the connecting portion 321 and is inserted into the annular space 50, and a recessed portion 3221 is formed between the stop plate 322 and the extension section 3212.
