The other end of the pipe body is connected with a detachable rubber joint. The rubber joint includes a connecting head which is sleeved inside the pipe body. An over-flow hole adapted to the aperture of the pump body pipeline is machined inside the connecting head. A sealing part is connected to the end of the connecting head. A connecting flange II is provided on the outer side of the other end of the pipe body, and flange connecting holes II are machined around the connecting flange II. The flange connecting holes II are waist-shaped holes.

[0006] Further, the pipe body includes a seamless steel pipe and a reducing pipe, and the seamless steel pipe and the reducing pipe are welded to form the pipe body.

[0007] Further, the connecting flange I is arranged on the reducing pipe, the rubber joint and the connecting flange II are arranged on the seamless steel pipe, and an annular baffle is connected to the end face of the seamless steel pipe to support the sealing part of the rubber joint.

[0008] Further, the connecting head adopts a conical structure.

[0009] Compared with the existing technology, the quick-change joint for a test bench pipeline of the utility model has the following beneficial effects:

[0010] 1. By adopting the quick-change joint, the time for replacing the rubber flexible joint is saved, the test efficiency is improved, and the production capacity is increased;

[0011] 2. It is convenient for installation, disassembly, replacement and maintenance, reduces the use cost, improves the convenience of work, and reduces the labor intensity of workers;

[0012] 3. Long service life, only the rubber joint needs to be replaced, reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.

[0020] As Figures 1 to 4 shown, a quick-change joint for a test bench pipeline includes a pipe body 1. On the outer side of one end of the pipe body 1, a first connecting flange 2 is provided. Flange connection holes 3 are machined around the first flange connection hole 2. At the other end of the pipe body 1, a detachable rubber joint 4 is connected. The rubber joint 4 includes a connector 411. The connector 411 is sleeved in the pipe body 1. An over-flow hole adapted to the aperture of the pump body pipeline is machined in the connector 411. The connector 411 adopts a conical structure, which on the one hand clamps it in the pipe body 1, and on the other hand plays a role in guiding the flow. The end of the connector 411 is connected with a sealing part 412. The sealing part 412 plays a role in sealing with the pump body pipeline. On the outer side of the other end of the pipe body 1, a second connecting flange 5 is provided. Flange connection holes 6 are machined around the second connecting flange 5. The flange connection holes 6 are waist-shaped holes to adapt to the connection with water pumps of different models.

[0021] In this embodiment, the pipe body 1 includes a seamless steel pipe 111 and a reducing pipe 112. The seamless steel pipe 111 and the reducing pipe 112 are welded to form the pipe body. The first connecting flange 2 is provided on the reducing pipe. The rubber joint 4 and the second connecting flange 5 are provided on the seamless steel pipe 111. The connecting head 411 of the rubber joint 4 is sleeved on the seamless steel pipe 111. An annular baffle 7 is connected to the end face of the seamless steel pipe 111, and the annular baffle 7 supports the sealing portion 412 of the rubber joint 4.

[0022] As Figure 5 shown, the quick-change joint is connected between the pump body pipeline 8 and the test bench pipeline 9. Among them, the first connecting flange 2 is fixedly connected to the flange on the test bench pipeline 9 through the first flange connection hole 3. Select a suitable rubber joint 4 according to the caliber of the water pump to be tested. Since only the rubber joint 4 needs to be replaced and the entire quick-change joint does not need to be disassembled, a large amount of time can be saved. During use, insert the rubber joint into the pipe body 1, cooperate with the end face of the annular baffle 7, and then connect the flange on the pump body pipeline 8 to the second flange connection hole 6 on the second connecting flange 5 through hexagon head bolts. After the bolts are firmly fixed, the water pump can operate normally for testing.

[0023] The present invention is not limited to the described embodiments. Those skilled in the art can still make some modifications or changes without departing from the spirit of the present invention, that is, within the scope of disclosure. Therefore, the scope of the protection of the present invention is subject to the scope defined by the claims.
