Liquid rocket engine valve test measurement and control system

Abstract

The invention provides a liquid rocket engine valve test measurement and control system which comprises a high-low temperature environment subsystem, an explosion-proof box system, a helium detectionsubsystem, a data acquisition subsystem and an industrial personal computer. The high-low temperature environment subsystem is used for providing a temperature and humidity environment required by gaspath high-temperature, normal-temperature and low-temperature tests for the tested valve; the explosion-proof box system is used for providing a test environment for the tested valve to complete a sealing test and a service life test under a normal temperature condition; the helium detection subsystem is used for providing a sealing test environment for the tested valve meeting the preliminary sealing requirement; the data acquisition subsystem is used for acquiring pressure, temperature, humidity, leakage amount and current parameters; and the industrial personal computer is used for dynamically adjusting parameters required by the test provided for the tested valve by the high and low temperature environment subsystem, the explosion-proof box system and the helium detection subsystem according to the parameters acquired by the data acquisition subsystem. The safety, the stability and the accuracy of the test can be improved, so that the time and the labor cost are saved.

Description

technical field [0001] The application belongs to the technical field of measurement and control, and in particular relates to a liquid rocket engine valve test measurement and control system. Background technique [0002] At present, the domestic liquid rocket engine valve test is an important process in the valve production, inspection and maintenance process. The test results can directly reflect the relevant performance indicators of the valve. At present, the test process of liquid rocket engine valves is mostly purely manual operation, and the high and low temperature environments required for the test are simulated by soaking in high and low temperature media respectively, and the measuring equipment is mechanical instruments. Accuracy is greatly affected by the operator's experience. In addition, during the test, improper operation of personnel may damage the tested product and cause certain personal safety hazards. SUMMARY OF THE INVENTION [0003] In order to o...
