Background

Piping systems for transporting fluids are widely used in industry, and it is usually necessary to connect a plurality of pipes with each other by joints according to different piping or equipment requirements. Common bonding methods include welding and thread bonding, depending on the type of fluid to be transported.

The weld joint is suitable for use with high pressure fluids due to its high joint strength, while the thread joint is suitable for use with low pressure fluids due to its low joint strength. However, the interface between the welding and the thread joint is exposed to the external environment for a long time, and is prone to corrosion, oxidation or rusting. To improve this problem, heat shrinkable sleeves, industrial tapes or coatings are usually further coated and protected at the interface to avoid direct contact between the interface and the external environment.

Structural matching between the coating and the tube is a concern, and a filler is usually added to compensate for the mismatch between the coating and the tube. However, when the filler is filled, since it is difficult to observe the filling degree, if the filler is excessively filled, an overflow phenomenon occurs; if the filling amount is too small, the filling is not complete, which affects the degree of adhesion.

Detailed Description

The detailed description and technical contents of the present invention will now be described with reference to the accompanying drawings as follows:

referring to fig. 1A and 1B, the present invention relates to an anti-overflow fluid pipeline assembly, including a first pipeline 10, a second pipeline 20, a connecting element 30 and a filling material 40, wherein the first pipeline 10 has a first outer wall 11, the second pipeline 20 has a second outer wall 21, the second pipeline 20 is connected to an end of the first pipeline 10, and the connecting element 30 connects the first pipeline 10 and the second pipeline 20. In the present embodiment, the first pipeline 10 and the second pipeline 20 are both circular pipes and have different diameters, and in other embodiments, the first pipeline 10 and the second pipeline 20 may be pipes with other cross sections and have the same or different diameters.

The connecting element 30 includes a sleeve 31 and a sleeve ring 32, the sleeve 31 includes a first connecting section 311 and a second connecting section 312, the first connecting section 311 is sleeved on the first outer wall 11 of the first pipeline 10, and the second connecting section 312 is sleeved on the second pipeline 20. In this embodiment, the inner diameter of the sleeve 31 is larger than the outer diameters of the first pipeline 10 and the second pipeline 20, the first connecting section 311 of the sleeve 31 and the first outer wall 11 of the first pipeline 10 may adopt an interference fit, a transition fit or a clearance fit, an annular space 50 is formed between the second connecting section 312 of the sleeve 31 and the second outer wall 21 of the second pipeline 20, and in this embodiment, the sleeve 31 further includes at least one filler hole 313 disposed between the first connecting section 311 and the second connecting section 312. The annular space 50 has a filling end 51 and an open end 52, the filling end 51 is adjacent to the filling hole 313, and the open end 52 is far from the filling end 51.

The collar 32 includes a connecting portion 321 and a blocking plate 322, the connecting portion 321 includes a protruding portion 3211 and an extending portion 3212, the protruding portion 3211 extends radially outward to abut against an end portion 3122 of the second connecting portion 312, and the extending portion 3212 extends axially and is connected to an inner wall surface 3121 of the second connecting portion 312. In this embodiment, the second connecting section 312 includes an internal thread structure 3123 disposed on the inner wall surface 3121, and the extending section 3212 includes an external thread structure 3213 screwed with the internal thread structure 3123. The baffle 322 extends from the connecting portion 321 to be inserted into the annular space 50, and a recess 3221 is formed between the baffle 322 and the extending portion 3212, further, the annular space 50 has an outer side 53 close to the second connecting portion 312 and an inner side 54 close to the second outer wall 21, the baffle 322 extends from the outer side 53 to the inner side 54 in an inclined radial direction R, in addition, the baffle 322 has a thickness gradually thinner along the inclined radial direction R, in other words, the baffle 322 is in a thin sheet shape gradually tapering toward a tip end; in other embodiments, the baffle 322 may have a uniform thickness and be in the shape of a thin plate with a uniform thickness.
