[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] The following is a further detailed description of the embodiments of the present application in conjunction with the attached Figures 1-4 drawings.

[0027] Embodiment 1

[0028] Please refer to Figures 1-4 and this embodiment provides a technical solution: A pipeline assembly of a valve test bench with a reflux function, including: a pipeline main body 1, a connecting flange 2 and a reflux mechanism 3

[0029] Two sets of holes are provided on the outer wall of the pipeline main body 1, which can play a role in stably fixing between structures inside the opened holes. Connecting flange plates 2 are welded at both ends of the pipeline main body 1. The connecting flange plates 2 are in the shape of a circular ring, and the circular connecting flange plates 2 can be sleeved on the outer wall of the pipeline main body 1, so as to maintain effective adhesion during the welding connection process. And a sealing ring is clamped at one end of the outer wall of the connecting flange plate 2, which can play an effective sealing role during the fitting process between structures.

[0030] The reflux mechanism 3 is arranged on the outer wall of the pipeline main body 1. The reflux mechanism 3 can enable the liquid in the pipeline main body 1 to flow stably. The reflux mechanism 3 includes a first reflux pipe 301 welded in one set of holes of the pipeline main body 1. The first reflux pipe 301 can play a role in transporting the liquid in the pipeline main body 1. A second reflux pipe 302 welded in the other set of holes of the pipeline main body 1 can transport the subsequent liquid back into the pipeline main body 1 through the second reflux pipe 302. A fixed box body 303 fixed at the other ends of the first reflux pipe 301 and the second reflux pipe 302 can enable the liquid to be transported into the first reflux pipe 301 through the second reflux pipe 302, so as to carry out the subsequent liquid circulation effect. A round hole is provided inside the fixed box body 303, which can provide a through connection for the internal structure. And a bearing is welded at the round hole of the fixed box body 303, which can play a role in fixing the internal structure and keep the internal fixed structure rotating stably during the fixing process.

[0031] A connecting rotating shaft 308 fixed inside the bearing of the fixed box body 303 can rotate stably inside the bearing of the fixed box body 303, so as to drive the structures on the shaft to rotate synchronously. A rotating blade 309 clamped and fixed on the connecting rotating shaft 308, and the rotating blade 309 is arranged inside the fixed box body 303. The rotating blade 309 can drive the liquid inside the fixed box body 303 to carry out stirring and transporting work during the synchronous rotation process. A driving motor 307 fixed on the outer wall of the fixed box body 303, and the output end of the driving motor 307 is connected to the connecting rotating shaft 308. The driving motor 307 can enable the connecting rotating shaft 308 connected to the output end to carry out stable continuous rotation work.

[0032] Both ends of the pipeline main body 1 are connected to the structures on both sides through the connecting flange plates 2, so as to carry out subsequent detection work. The liquid in the pipeline main body 1 flows through the second return pipe 302 into the interior of the fixed box body 303, and the liquid in the fixed box body 303 flows through the first return pipe 301 into the interior of the pipeline main body 1, thus realizing the effect of reflux. When the liquid flows into the interior of the fixed box body 303, by starting the driving motor 307, the driving motor 307 will drive the connecting rotating shaft 308 connected to the output end to rotate. During the rotation of the connecting rotating shaft 308, the rotating blades 309 inside the fixed box body 303 will be driven to rotate. At this time, the rotating blades 309 will drive the liquid to achieve rapid circulation.

[0033] Embodiment 2

[0034] Please refer to Figures 1-4 , this embodiment provides a technical solution: a pipeline assembly of a valve test bench with a reflux function, including: a rectangular hole 304, a transparent toughened glass cover 305, a clamping block 306 and a positioning block 310;

[0035] The rectangular hole 304 is opened directly above the fixed box body 303. The rectangular hole 304 can facilitate the operator to observe the state inside the fixed box body 303 from the outside, and the size of the rectangular hole 304 is adapted to the size of the rotating blades 309, which can facilitate the subsequent disassembly and removal of the rotating blades 309 through the rectangular hole 304 when they are damaged. The transparent toughened glass cover 305 is attached directly above the rectangular hole 304. The transparent toughened glass cover 305 can facilitate the operator to observe the state inside the fixed box body 303 from the outside, and can prevent foreign impurities from entering the interior of the fixed box body 303. The outer wall of the transparent toughened glass cover 305 is provided with a metal frame, which can improve the rigidity of the overall structure of the transparent toughened glass cover 305, and sealing strips are bonded around the metal frame of the transparent toughened glass cover 305, which can effectively seal the connection when it is fitted and fixed to the fixed box body 303.

[0036] The clamping blocks 306 are welded on both sides of the metal frame of the transparent toughened glass cover 305, and the cross-sectional shape of the clamping blocks 306 is "L". The clamping blocks 306 can play a role in stably fixing and connecting the structures. The positioning blocks 310 are welded on the outer wall of the fixed box body 303, and the positioning blocks 310 are engaged with the clamping blocks 306 directly above. The positioning blocks 310 can be engaged and fixed with the clamping blocks 306, so as to stably fix the transparent toughened glass cover 305 on the outer wall of the fixed box body 303.

[0037] When the liquid in the fixed box body 303 flows, the state inside the fixed box body 303 can be observed through the transparent toughened glass cover 305 in the rectangular hole 304. If the connecting rotating shaft 308 or the rotating blade 309 is damaged, the deformation of the clamping block 306 will no longer be engaged on the positioning block 310, so that the transparent toughened glass cover 305 connected to the clamping block 306 can be disassembled, and then the structure inside the fixed box body 303 can be operated through the rectangular hole 304.

[0038] The implementation principle of a pipeline assembly of a valve test bench with a reflux function in this application is as follows:

[0039] First, both ends of the pipeline main body 1 are connected to the structures on both sides through the connecting flange plates 2 for subsequent detection work. The liquid in the pipeline main body 1 flows through the second reflux pipe 302 into the interior of the fixed box body 303, and the liquid inside the fixed box body 303 flows through the first reflux pipe 301 into the interior of the pipeline main body 1, thus achieving the reflux effect.

[0040] Second, when the liquid flows into the interior of the fixed box body 303, by starting the driving motor 307, the driving motor 307 will drive the connecting rotating shaft 308 connected to the output end to rotate. During the rotation of the connecting rotating shaft 308, the rotating blade 309 inside the fixed box body 303 will be driven to rotate. At this time, the rotating blade 309 will drive the liquid to flow quickly.

[0041] Finally, when the liquid in the fixed box body 303 flows, the state inside the fixed box body 303 can be observed through the transparent toughened glass cover 305 in the rectangular hole 304. If the connecting rotating shaft 308 or the rotating blade 309 is damaged, the deformation of the clamping block 306 will no longer be engaged on the positioning block 310, so that the transparent toughened glass cover 305 connected to the clamping block 306 can be disassembled, and then the structure inside the fixed box body 303 can be operated through the rectangular hole 304.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
