Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of valve performance testing and evaluation, and particularly relates to a working performance evaluation method and device for an integrated valve assembly. BACKGROUND

[0002] The working performance of an integrated valve under combined vibration, high temperature and impact conditions is directly related to the safety and reliability of the operation of key equipment. The current evaluation method has significant limitations: the traditional device can only simulate a single environmental stress (such as pure vibration or static high temperature) independently, and it is difficult to truly simulate the multi-stress synergistic effect in actual service; at the same time, due to the lack of adjustable fixing mechanism to flexibly adjust the installation state, the influence of the fixed position difference on the performance is difficult to quantify; in addition, the sensors are usually arranged only at the valve inlet or a single outlet, and the asymmetric response of the integrated valve branch flow / pressure cannot be captured, resulting in incomplete performance monitoring coverage.

[0003] The existing evaluation process generally relies on subjective experience judgment or single parameter threshold setting, and lacks quantitative computer mechanism based on multi-channel real-time data dynamic comparison (such as reference environment data and interference environment data). For example, a valve high temperature sealing test device (CN222895873U) explicitly limits the test environment to static high temperature, which cannot simulate vibration-impact combined load, nor capture the asymmetric response of multiple branches, making it difficult to evaluate the performance degradation of the valve under real combined working conditions.

[0004] Therefore, it is urgent to develop an integrated evaluation scheme that supports vibration-high temperature-impact combined loading, multi-outlet synchronous monitoring and variable installation position. SUMMARY

[0005] Therefore, the present application provides a working performance evaluation device and method for an integrated valve assembly, which can objectively evaluate the working performance of the integrated valve, improve the test efficiency, and solve the problem of difficult performance evaluation of the integrated valve assembly under combined working conditions.

[0011] Further, the vibration device includes a base, a spring telescopic column, a vibration platform, and a vibration motor; the spring telescopic column is welded on the base, the vibration platform is supported on the spring telescopic column, the vibration motor is arranged below the vibration platform, and the vibration motor drives the vibration platform to vibrate, thereby providing a vibration environment for the integrated valve assembly on the vibration platform.

[0012] Further, the composite environment loading component further includes a central controller, which is connected to the vibration motor, the temperature control cabin temperature control unit, the high-pressure air gun, the three-way valve, and the terminal valve through electrical signals respectively.
