[0002] With the development and application of new energy technologies, the closely related thermal management systems are increasingly used in new energy. Thermal management systems are also gradually tending towards integration and simplification, that is, using fewer components to complete more functions. Therefore, the role of multi-way valves in thermal management systems is becoming more and more important. Existing multi-way valves require a lot of verification work during the research and development, verification and production process. The multi-way valves need to be tested for performance, durability, leakage and other performance. At this time, how to quickly and effectively verify their performance is particularly important.

[0003] At present, the performance test devices for multi-way valves mostly use multiple tools to test different flow paths respectively, which increases the production cost of the tools. At the same time, during the test process, when testing different channels, it is necessary to replace the tools that match the channel for testing, resulting in low test efficiency of the multi-way valve; at the same time, due to frequent disassembly of the tools, the connection between the multi-way valve and the tools becomes loose, which easily leads to test deviation.

[0012] Preferably, a protrusion is provided on the side wall of the position-limiting pressing block facing the sample to be tested, and a groove for the protrusion to be inserted into is provided on the sample to be tested.

In the embodiment of the present application, a plurality of connecting tubes 4 are sequentially arranged on the side wall of the test seat 1.

[0021] Reference Figure 1 and Figure 2 In order to improve the sealing between the test sample 10 and the test seat 1, a sealing ring 5 is installed on the test seat 1. A mounting groove 6 is provided on the side of the test seat 1 facing the test sample 10, and the sealing ring 5 is embedded in the mounting groove 6. In order to improve the stability of the sealing ring 5 in the mounting groove 6 and improve the sealing effect of the sealing ring 5, a plurality of protrusions are provided on the side wall of the sealing ring 5. The protrusions are in close contact with the groove wall of the mounting groove 6, thereby improving the connection strength between the sealing ring 5 and the test seat 1 and reducing the possibility of the sealing ring 5 loosening.

[0022] Reference Figure 1 and Figure 2 The positioning assembly 2 is used to position the sample 10 to be tested. The positioning assembly 2 includes a positioning block 21 installed on the test seat 1 and sleeved on the sample 10 to be tested, and a limiting block 22 installed on the positioning block 21. The positioning block 21 is provided with a positioning groove 7 on the bottom surface facing the test seat 1, and the limiting block 22 is embedded in the positioning groove 7. In order to improve the positioning effect of the positioning block 21 on the sample 10 to be tested, a positioning piece is provided on the positioning block 21, and the positioning piece is used to connect the sample 10 to be tested and the positioning block 21. In the embodiment of the present application, the positioning piece uses a bolt, and the bolt fixes the sample 10 to be tested and the positioning block 21 together. The positioning block 21 is provided with a plurality of bolt holes, and the test seat 1 is provided with threaded holes corresponding to the bolt holes, so that the bolts can fix the positioning block 21 on the test seat 1, thereby improving the stability of the positioning block 21 on the test seat 1, and further improving the stability of the sample 10 to be tested on the positioning block 21.

The positioning pressure block 21 is used to control the distance between the test sample 10 and the test seat 1, ensure the compression rate of the sealing ring 5 between the test sample 10 and the test seat 1, and improve the sealing between the test seat 1 and the test sample 10.

[0024] Reference Figure 1 and Figure 2 In order to improve the stability of the limiting pressure block 22 on the positioning pressure block 21, a plurality of bolt holes are provided on the limiting pressure block 22, and threaded holes for tightening bolts are provided on the positioning pressure block 21. The limiting pressure block 22 is fixed to the positioning pressure block 21 by bolts.

[0025] Reference Figure 1 , Figure 2 and Figure 3 In the embodiment of the present application, the test piece to be tested uses an eight-way valve, and the test seat 1 adopts an octagonal symmetrical structure corresponding to the eight-way valve. In the specific implementation process, the test seat 1 of different shapes can be set according to the number of passages of the test piece. The test seat 1 of this embodiment adopts an octagonal symmetrical structure, which is used to balance each passage and improve the test stability. Each side wall of the test seat 1 is provided with two groups of symmetrically arranged threaded holes, and the connecting pipe 4 is installed in the threaded holes. The connecting pipe 4 is symmetrically arranged to ensure the integration of the test and the versatility of the installation angle, saving the tooling production cost. The test seat 1 is connected to the connecting pipe 4 by threads, which is convenient for the installation or disassembly of the connecting pipe 4 and has strong versatility. The positioning assembly 2 positions the eight-way valve, the limiting pressure block 22 positions the circumference of the eight-way valve, and the positioning pressure block 21 is used for axial positioning to prevent the eight-way valve from sliding during the test process, ensuring that the axial force of the eight-way valve is more balanced, and the test is more accurate and reliable.

[0026] The implementation principle of a multi-way valve performance test tool in the embodiment of the present application is as follows: first, place the limit pressure block 22 into the positioning groove 7, and then fix the limit pressure block 22 to the positioning pressure block 21 by bolts. The protrusion 8 on the limit pressure block 22 is embedded in the groove 9 of the sample to be tested 10, which plays a role in fixing the sample to be tested 10 and preventing the sample to be tested 10 from circumferential rotation during the test. After the groove 9 of the sample to be tested 10 is matched with the protrusion 8, the sample to be tested 10 is fixed together with the positioning pressure block 21 by bolts. The pressure between the sample to be tested 10 and the sealing ring 5 is adjusted by controlling the torque of the bolt.

[0027] After installation, the tooling of the present application can be used according to different passage detection modes. The pipelines in the test bench can be connected to the test system through quick connectors, and then different channel 3 modes can be controlled by controlling the rotation of the valve core inside the sample 10 to be tested.
