[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional test pipes, the thermal insulation capacity of the conveyed materials is weaker. When conveying materials that require thermal insulation, the temperature of the materials will change, which will affect the results of mechanical equipment testing and mislead testers. This device increases the thermal insulation capacity of the test pipe by adding an insulation structure to the test pipe, reduces the temperature change of the conveyed materials, and ensures the consistency of test results with actual use.

[0014] 2. When the material pipe is in use, the material flows in the pipe body. The insulation layer is the first insulation link. The insulation layer made of insulation material is used to insulate the pipe body. As the second insulation link, two layers of insulation are arranged at intervals. The heightening pad supports and isolates the two layers of insulation so that there is an air layer between the two layers of insulation. Air is a poor conductor of heat. The air layer is used to perform secondary insulation on the material pipe. The sealing rings are located at both ends of the insulation layer. The pressure of the connecting plate is used to make the two layers of insulation and the sealing rings fit tightly to achieve the effect of sealing the air layer space. The setting of two insulation links realizes the insulation effect of the pipe body, so as to solve the problem that most test machine material pipe devices have weak insulation ability for conveying materials, which easily causes the temperature of the material to change, thereby affecting the accuracy of the test results.

[0015] 3. When connecting the pipeline, the pipe body is connected to the connecting external threaded pipe through the conveying thread. The waterproof rubber layer is located on the pipe body and the connecting external threaded pipe to enhance the sealing. After the protective layer is placed on the inner side of the connecting plate, the bolts and nuts are threaded together. Turn the bolts to drive the connecting seats closer to each other, so that the diameter of the metal ring is reduced, and the connecting plate is pressed against the protective layer. The friction between the connecting plate and the protective layer is used to connect and fix the material pipe and the connecting internal threaded pipe. Finally, connect the connecting threaded pipe to the connecting internal threaded pipe, and connect the access threaded pipe to the inlet of the mechanical equipment to complete the installation and connection of the test machine material pipe.
