Description

Technical Field

[0001] The utility model relates to the technical field of three-way valve performance testing, and more particularly to a three-way valve performance testing system. Background Art

[0002] In circulating water cooling systems for power, electronics, wind power, and other applications, three-way valves are critical components, and their performance can significantly impact the overall performance of the system. Therefore, it's crucial to test various performance indicators of three-way valves. These include flow resistance, internal leakage, shutoff differential pressure, load, and lifespan reliability. These tests help ensure the reliability and stability of the three-way valves, thereby ensuring the proper operation of the entire system.

[0003] In existing technologies, the performance of three-way valves is primarily determined through theoretical engineering calculations. While this approach is simple, the results are often inaccurate. Furthermore, existing testing methods are fragmented and lack comprehensive performance testing. This can result in some performance indicators not being fully tested, increasing operational risks.

[0004] The existing three-way valve performance testing method has the following problems:

[0005] First, due to the inaccurate testing method, directly using this data may bring greater risks. Once a problem occurs, the consequences may be very serious, resulting in huge economic losses;
