[0001] The invention relates to the technical field of hydrogenation regulating system testing, in particular to a testing device for a hydrogenation regulating system. Background Art

[0002] During the hydrogenation process, a hydrogenation regulating system is required to control the amount of hydrogenation. After the design of the hydrogenation regulating system is completed, a test device is needed to test the system to observe whether the system can operate normally and prevent a faulty system from being directly introduced into the hydrogenation and affecting the hydrogenation station.

[0003] When the existing testing device is working, gas passes through the inside of the equipment. When the gas collides with the obstruction in the front direction, gas backflow will occur, so that the backflow gas affects the forward flowing gas and causes interference, causing the equipment to detect the gas flow rate incorrectly, resulting in the equipment's detection of the hydrogenation regulation system incorrectly.

[0004] Therefore, it is necessary to design a test device for the hydrogenation regulation system to address the above problems. Summary of the invention

[0045] 1. The present invention enables the gas to flow in one direction through a one-way valve, thereby preventing the gas passing through the middle pipe from knocking over the canvas board and forming a backflow, causing the backflow gas to affect the gas flowing forward inside the middle pipe, thereby affecting the rotation speed of the fan blades, resulting in an error in the gas flow rate detected by the equipment, and causing errors in the equipment's test of the hydrogenation regulation system.

The canvas board can be buffered by the elastic structure formed by the damping rod and the pressure sensor. At the same time, the pressure sensor can also detect the pressure of the gas on the canvas board, so that the wind speed generated by the gas flow can be calculated, and the gas flow inside the equipment can be calculated, so that the equipment has a dual flow detection function, thereby improving the accuracy of the equipment flow detection.

[0047] 3. The present invention can be connected to other pipes through the threads inside the connecting block, and then the inside of the sealing airbag is inflated so that the sealing airbag tightly wraps the other pipes, thereby preventing air leakage at the connection between the connecting block and other pipes, which affects the connection effect of the equipment and easily causes errors in the detection data of the equipment.

[0048] 4. The inner ring of the hemispherical ring of the present invention is connected to a flexible pipe. Pulling the connecting plate will pull the hemispherical ring out of the right pipe, so that the flexible pipe is fully unfolded and extended. Similarly, pushing the hemispherical ring into the right pipe will cause the flexible pipe to wrinkle together, thereby controlling the flexible pipe to shrink, making it easier for the equipment to be connected to other pipes.
