Embodiment 1

[0033] In order to solve the current situation of the lack of perfect and efficient air working environment simulation system control valve selection analysis methods and tools for the construction of aero-engine high-altitude test rigs in my country. The invention proposes a whole-process type selection method for a regulating valve, and develops a set of automatic type selection tool software for regulating valves based on the EN standard based on the Labview environment. Contains the following steps:

[0034] Step 1: According to the characteristics of the main test objects and the test subjects of the high-altitude platform, analyze and summarize the limit boundaries of the pressure, temperature and air flow required to simulate the intake and exhaust systems in the aerial working environment, as the basis for subsequent selection analysis.

[0042] The specific process of this implementation case is as follows: analyze the typical test points of the main test objects of a high-altitude simulation test bench to obtain the limit boundaries of the required pressure, temperature and flow regulation of the air inlet and exhaust simulation requirements of the aerial working environment. According to the principle of aerodynamic layout of the high-altitude test bench, the working boundary of the control valve on the pneumatic branch is calculated and analyzed to meet the requirements of the limit test point as the convergence condition, and the characteristic values ​​such as limit temperature, pressure and flow range are extracted. Based on the feature extraction value, in the selection software developed by the present invention, the key indicators such as the material, PN grade, wall thickness, flange and its parameters of the control valve are selected and analyzed based on the EN series standards.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to an automatic type selection method for a regulating valve of an aero-engine high-altitude simulation test bed. Background technique [0002] As the front-end adjustment device of the aerial working environment simulation system of the aero-engine high-altitude simulation test bench, the reliability of the regulating valve not only directly determines the operation safety of the engine and the high-altitude test equipment, but also indirectly affects the development and test progress of the aero-engine. The effect is self-evident. The same high-altitude test bench often has to adapt to multiple different test objects and many complex test subjects, and different test subjects need to simulate a working environment with wide and severe changes in air flow, pressure, and temperature, and long duration, etc. Harsh features. It is not only required that the regulating ability of the regu...
